Description

  The present invention relates to a cocoon processing system for processing cocoons, and in particular, a large amount of cocoons are present in comparison with an apartment building such as a restaurant building or a complex building in which accommodation facilities such as hotels and a large number of restaurants occupy. The present invention relates to a soot processing system installed in a building where it occurs.

  Conventionally, in accommodation facilities such as hotels, there are often multiple banquet halls and restaurants in the facility, and it is common to have commercial kitchens that cook according to the number of banquet halls and restaurants. is there. In addition, from such commercial kitchens, a large amount of so-called rice cakes such as scraps of vegetables, meat, seafood, etc. are generated during cooking, and leftover food is disposed of after cleaning. The soot generated in this case is collected by employees in the commercial kitchen and the cleaning staff who pack the bags in the commercial kitchen and transport them to the firewood collection site in the building, from which they are regularly transported by the carrier. It is transported to the treatment plant by car and processed. In restaurants buildings and complex buildings where a large number of restaurants are occupying, a large amount of soot is generated from each restaurant and is treated in the same manner as in the case of accommodation facilities.

  In addition to the kitchen, these commercial kitchens generate kitchen wastewater with high concentrations of BOD, SS, and n-Hex by using water when cooking, cooking utensils, and washing dishes. In the case of the accommodation facility described above, the kitchen wastewater in each kitchen has a large scale per each commercial kitchen, and a plurality of kitchen wastewaters are provided, so that a large amount of kitchen wastewater is generated. In the case of restaurant buildings, complex buildings, etc., even if the size of the commercial kitchen at each store is not large, many stores coexist, so a large amount of kitchen drainage is the same as in the case of accommodation facilities. Will occur. If there are many buildings that generate such a large amount of kitchen wastewater within the treatment area of the same sewage treatment plant, a treatment load exceeding the treatment capacity of the sewage treatment plant will be applied, and the treatment of water quality below a predetermined value will occur. There is a risk that water cannot be maintained. In order to prevent such a situation, it is a wastewater treatment device that purifies the kitchen wastewater to a quality below the discharge standard value in the building for buildings where the daily amount of kitchen wastewater exceeds a predetermined value by law. Installation of abatement facilities is obligatory. That is, the kitchen wastewater of each commercial kitchen in the building is collected by a kitchen drainage pipe, sent to a wastewater treatment device, where it is purified and then discharged into the sewer.

  On the other hand, even in collective housing, the amount of emissions itself is small, but soot is generated in each household (unit). In the past, each resident packed their own trash and transported it to a shared garbage collection facility or public trash collection facility, and a garbage truck collected the trash bags from the trash collection site to a garbage disposal site. And was incinerated there. However, since garbage collection by garbage trucks is not performed every day, the occurrence of odors and insect damage due to soot collected at the garbage collection site has been a problem. Therefore, in recent years, a soot processing apparatus has been developed in which a pulverizer capable of pulverizing solids such as soot is installed between a sink sink drain and an instrument drain pipe. Residents poured the culm into a sink and pulverized the culm with a pulverizer, and discharged it out of the house along with the water for cleaning the pulverizer and other domestic wastewater.

  However, the mixed waste water of the pulverized soot and washing water etc. is higher than BOD, SS, and n-Hex compared to normal domestic waste water. If there were many apartment houses with this dredging device installed in the same sewage treatment plant treatment area, there was a risk of exceeding the limit of the treatment load of the sewage treatment plant. Also, in order to reduce the processing load at the sewage treatment plant, even if you try to purify the wastewater treatment equipment by combining the mixed wastewater and groundwater discharged from each dwelling unit and washing water into one, Since the amount of drainage becomes large, the wastewater treatment device becomes large-scale, and the cost burden of the resident of the apartment house becomes great. In many cases, a biological treatment device that uses a purification action of microorganisms with low running cost is applied to a wastewater treatment device of a cocoon treatment device. The biological treatment apparatus has a large purification treatment capacity due to the contact time between the microorganisms and the wastewater to be treated. When the amount of treated water increases, the volume of the treated water tank inevitably increases. For this reason, the sink sink drainage where the soot treatment device is installed (crushed soot when using the soot treatment device and water for washing the grinder, drainage when using a normal sink) and others While other domestic wastewater (toilet, bathroom, washroom, etc.) is a separate drainage system, the other domestic wastewater system is allowed to be discharged directly into the sewer system without wastewater treatment as before. The drainage of sink sinks equipped with dredging treatment equipment is stipulated by laws and regulations, etc. so that it is combined into a single system and purified to within the discharge standard value by the wastewater treatment equipment before being discharged into the sewer. .

  In the case of apartment houses, a crusher is installed at the drain outlet of the sink sink of each dwelling unit, the drainage of each dwelling unit is collected with a drain pipe, and the wastewater treatment system purifies mixed wastewater containing dredging by a wastewater treatment system. It was able to solve the problems of odor and insect damage caused by moths, and had a good effect. So far, the inventions described in Patent Document 1 to Patent Document 3 below have been proposed for the soot processing system.

  Patent Document 1 discloses a bag processing system for an apartment house. This soot processing system is mainly composed of a crushing device, a branch pipe, a main pipe and a separator. In this cocoon treatment system, first, a crushing device is provided adjacent to the kitchen sink in each household, and the crusher is pulverized by the crushing device and is flowed to a branch pipe together with water. The mixture of water and water from each branch pipe is merged into the main pipe and separated into solid water and liquid water by a separator installed on the lowest floor of the building and connected to the main pipe. The The separated soot is carried out of the building by a transport vehicle, and the liquid water is discharged into the sewage.

  Patent Document 2 describes a soot processing apparatus mainly composed of a pulverizing apparatus, a dehydrating apparatus, a biological processing apparatus, and an incineration apparatus. In this dredging device, the dredger is pulverized with a pulverizer with a pulverizer to form a slurry, solid-liquid separated into a solid content and a desorbed liquid by a dehydrator, and the desorbed liquid is purified by a biological treatment apparatus, Can be incinerated with an incinerator to reduce the volume of waste generated.

  Patent Document 3 describes a wastewater treatment system composed of a pulverization part, a drainage pipe part, a separation part, a solid matter treatment part, a biological treatment part, a sedimentation part, and a storage part. In this wastewater treatment system, first, the slag is pulverized together with the washing water supplied from the water supply unit in the pulverization unit, and is conveyed to the separation unit in the drainage piping unit. In the separation section, solid liquid is separated into solid waste and wastewater, and the wastewater is purified by microorganisms in the biological treatment section, surplus microorganism-derived sludge is separated in the sedimentation section, and the supernatant treated water is separated into sewers and combined treatment septic tanks. To be released. On the other hand, the sludge separated in the sedimentation part is returned to the separation part, and transferred to the solids treatment part with a screw conveyor together with the soot solids, and the solids treatment part is reduced in volume by decomposition treatment with microorganisms. It has become.

JP-A-62-240203 (first embodiment, FIG. 1) Japanese Patent Laid-Open No. 7-19436 (paragraph numbers [0007 to 0012], FIG. 1) JP 2002-282899 A (paragraph number [0029-0037], FIG. 2)

  Most of the conventional dredging treatment systems are for apartment buildings. In addition to the mixed drainage of pulverized dredging and washing water, living wastewater from the sink (drainage during cooking, dishwashing drainage, etc.) is also biologically treated. System. The amount of dredging generated in apartment buildings is very small compared to the amount generated in commercial kitchens, and domestic wastewater from sink sinks is not so high in BOD compared to kitchen wastewater discharged in commercial kitchens. Since n-Hex is also low, BOD, SS and n-Hex in the mixed waste water of pulverized slag and domestic wastewater are not so high. For this reason, the soot treatment system for apartment buildings uses a simple treatment system biological treatment device to simultaneously treat pulverized soot and domestic wastewater from the sink sink, and still satisfy the emission standards set by law. It was done.

  However, the kitchen wastewater generated from commercial kitchens has a high concentration of BOD, SS and n-Hex and a large amount of wrinkles. Therefore, the mixed waste water of kitchen waste water and pulverized waste water has very high values for BOD, SS, and n-Hex. For this reason, in the soot processing system for apartment houses, it is not possible to process the biological processing apparatus to below the emission standard value. In order to be able to purify to the emission standard values stipulated by laws and regulations, a biological treatment device with a complicated and large multi-stage treatment flow is essential, the installation space for the biological treatment device is large, the initial cost and the running cost are large, Since it becomes an uneconomical system, a method of pulverizing cocoons and purifying them together with kitchen wastewater using a biological treatment apparatus has been hardly adopted.

  Even if a cocoon treatment system is used that sends the crushed soot to a biological treatment device without separating it into solid-liquid separation and performs biochemical treatment there, the crushed soot and the organic matter in the wastewater are aerobic microorganisms. Or it decomposes | disassembles by anaerobic microorganisms and a lot of sludge remains as a solid substance. The remaining sludge is biological sludge that is aerobic microorganisms or anaerobic microorganisms that decompose organic matter in the soot to extract energy and grow based on that energy, so it has very low energy compared to the original soot. It will not be left. For this reason, sludge can be used only for very limited uses such as compost, incineration and use as a raw material for construction materials, and as a raw material for cement. It was also a problem.

  In the housing treatment system for an apartment house shown in Patent Document 1, in the case of an apartment house, the distance between the kitchen where the crushing device (pulverizer) for crushing the straw is installed and the main pipe (drainage stack) is The length of the branch pipe (drainage horizontal branch pipe) is relatively short. In order to transport the crushed soot to the separator, it is necessary to flow down the branch pipe together with an amount of water that can be transported from the crushing device to the main pipe, but the length of the branch pipe is short, The crushed soot can be transported with a relatively small amount of water.

  However, in the case of a kitchen such as an accommodation facility, the distance of the drainage side branch pipe from the pulverizer to the drainage stack is often long. For this reason, when it is going to apply the dredging processing system for apartment buildings shown in patent documents 1 to the dredging processing system in kitchens, such as an accommodation facility, it is necessary to increase the amount of water supplied to a crusher, and usually a building Since a plurality of pulverizers are installed in the interior, the amount of water supply used increases, which is a problem.

  In the soot processing apparatus shown in Patent Document 2, solids (ground solids) are separated from the wastes made into a slurry by a pulverizer (pulverizer) with a dehydrator (solid-liquid separator), and further an incinerator The incineration process can reduce the solid content to about 1/20. However, incineration of the solid content consumes energy derived from organic matter that the soot has, and the remaining ash leaves almost no energy, which is extremely high enough to be used as a raw material for construction materials. However, it can only be used for limited purposes.

  In the soot treating apparatus shown in Patent Document 3, the volume of the soot solid and sludge mixture transferred to the solids treating unit is reduced by decomposition treatment with microorganisms or the like. Since the microorganisms consume energy derived from organic substances during decomposition, very little energy is left in the solids after volume reduction, and they are used as compost. As a raw material for cement, it can be used only for very limited purposes, and it has been a problem.

  Moreover, even if it was taken out of the system without being decomposed by microorganisms in the solid matter processing part, the solid matter of the potato that has a lot of organic matter-derived energy and the energy derived from the organic matter were consumed. Since it is stored in a mixed state with the sludge derived from the surplus microorganisms later, the share of energy derived from organic matter in the total weight (total capacity) decreases, and this is effectively used in bioplants, etc. When trying to do so, it was inefficient and problematic.

  The present invention has been made to solve the above-described problems. While reducing the volume of the soot, it suppresses the loss of energy derived from the organic matter contained in the soot as much as possible, and has an extremely high effective utilization. An object of the present invention is to provide a soot processing system that can take out the food.

  In order to solve the above-described problems, a dredging treatment system according to the present invention includes a kitchen drain pipe installed in a building, a crusher installed in a plurality of locations, and crushing the fridge, and water supply for supplying water to the crusher A solid-liquid separator for solid-liquid separation of the pulverized soot and water mixed waste water into pulverized solids and a separated liquid, and a separated liquid transfer for transferring the separated liquid from the solid-liquid separator to the kitchen drain pipe It consists of a tube.

  According to a second aspect of the present invention, there is provided a biological treatment apparatus for receiving and purifying a mixed liquid of kitchen wastewater and separated liquid from a kitchen drainage pipe.

  The straw processing system according to claim 3 of the present invention is a kitchen drain pipe installed in a building, a pulverizer that is installed at a plurality of locations and pulverizes the cocoon, a water feeder that supplies water to the pulverizer, A cocoon transfer pipe that transfers pulverized slag and water mixed effluent to a kitchen drain pipe, and a solid-liquid separator that receives the kitchen sewage and mixed effluent from the kitchen sewage pipe and separates them into crushed solids and separated liquids. And a biological treatment apparatus for receiving and purifying the separated liquid.

  According to a fourth aspect of the present invention, there is provided a soot processing system including a dryer for drying the pulverized solid matter.

  According to a fifth aspect of the present invention, there is provided a soot treatment system comprising a solubilizing device for solubilizing a ground solid.

  According to the soot processing system according to the present invention, the soot can be pulverized by a pulverizer, the separated liquid can be drained into a kitchen drain pipe by a solid-liquid separator, and the pulverized solid can be separated and taken out. As a result, compared to the original pestle, the crushed solids can remove some moisture and reduce the weight, and by pulverizing the pestle, the gaps when the individual caskets are stacked become smaller, so The overall volume of the bag can be reduced. It is possible to significantly reduce the transportation work load caused by manpower from the place where the cocoon is generated to the temporary storage place of the cocoon in the facility. In addition, the transportation cost from the temporary storage location of the soot to the processing site of the soot can be reduced, and furthermore, the fuel consumption of the transport vehicle can be reduced, which can contribute to reducing the environmental load.

  According to the soot processing system according to the present invention, the soot is crushed, the mixed waste water of the crushed soot and water is subjected to solid-liquid separation, and the ground solid after the solid-liquid separation is treated with aerobic microorganisms or anaerobic microorganisms. By carrying it out without performing the incineration process, it is possible to take out the pulverized solid with less moisture while maintaining the energy held by the organic matter in the soot almost as it is. This pulverized solid has a wider application than sludge.For example, methane can be taken out by methane fermentation treatment, hydrogen can be taken out by hydrogen fermentation treatment, or biogas can be taken out at a so-called bioplant. There is an effect that the energy possessed by firewood can be used effectively.

  When performing methane fermentation treatment or hydrogen fermentation treatment using koji as a raw material, it is necessary to put a large amount of koji into a large-capacity fermenter for processing in order to carry out stable treatment. It is necessary to maintain a high temperature within a certain range. Even in an accommodation facility where a lot of soot is generated per day, the amount of soot generated from one building is insufficient to perform a stable fermentation process such as methane. The installation of a bioplant that performs a fermentation process such as methane on one building is not very cost-effective considering the initial cost and running cost. It is realistic to install a bioplant at another location and collect firewood from multiple buildings. In addition, when the koji is added to the fermenter, the temperature in the vessel is temporarily lowered due to the influence of moisture contained in the koji. In order to perform a more stable fermentation process such as methane, the rate of decrease in the tank temperature decreases as the amount of water contained in the straw decreases, and more efficient processing becomes possible.

  In the cocoon treatment system according to the present invention, a pulverizer for pulverizing the cocoon is installed at a predetermined place such as a kitchen in a building, and a cocoon with a small amount of water can be obtained simply by installing a solid-liquid separator for separating pulverized solids. Since it can be taken out, it is easy to transport the straw from each building to the bioplant, and there is an effect that a fermentation process such as methane can be realized at a lower cost. Moreover, since the koji with a small water content can be taken out, there is an effect that a more efficient fermentation process such as methane can be performed.

  In the case of the soot processing system according to the first aspect of the present invention, the soot is pulverized by the pulverizer and then the pulverized solid matter is removed by the solid-liquid separator, and only the separated liquid is drained to the separated liquid transfer pipe. The pulverized solid does not flow into the separated liquid transfer pipe or the kitchen drain pipe. For this reason, in the horizontal piping part of the kitchen drainage pipe, even when the drainage flow rate of the kitchen drainage is small and the transport capacity of the solid matter is reduced, there is an effect that the crushed solid matter does not stay at the bottom of the horizontal piping. is there.

  In the case of the soot treatment system according to the invention described in claim 2, the separation liquid obtained by separating the mixed waste water of pulverized soot and water by the solid-liquid separator is purified by the biological treatment device together with the kitchen waste water. In addition, in the case of the soot treatment system according to each of the inventions according to claims 3 to 5, the ground waste water and the mixed waste water are combined with the kitchen waste water, and the solid matter is removed by the solid-liquid separator. Since the separation liquid after separation is purified by the biological treatment apparatus, the following effects are obtained.

  In the case of a building where a kitchen is installed in a building such as a hotel, restaurant building, complex building, etc., and the amount of water discharged in the kitchen is greater than the amount stipulated by law, the quality of the kitchen wastewater is below the discharge standard value. It is obligated by law to install a detoxification facility that cleans up. In new buildings that require the installation of abatement equipment, the mixed wastewater from crushed firewood and water is purified with a biological treatment device along with kitchen wastewater without solid-liquid separation for the purpose of sharing with the harmony equipment. When installing a treatment system, it is necessary to purify the mixed wastewater with a very high concentration and the kitchen wastewater with a relatively high concentration at the same time. Don't be. For this reason, both the initial cost and the running cost for installing the soot processing system become significantly high. In addition, in existing buildings that are obligated to install abatement equipment, the space in which biological treatment equipment can be installed is limited, and this dredging system cannot be introduced, and only normal kitchen drainage is available. In many cases, only a biological treatment device for purification treatment is installed and used only as a detoxification facility.

  On the other hand, in the cocoon treatment system according to each of the inventions according to claims 2 to 5, since the pulverized solid matter is separated by the solid-liquid separator, the objects to be treated by the biological treatment apparatus are the kitchen wastewater and The mixed waste water is separated from the pulverized solids with a slightly higher concentration but a small amount of the separated liquid compared to the kitchen waste water, and the mixed waste water has a slightly higher concentration than the normal kitchen waste water. For this reason, if the waste treatment system according to claims 2 to 5 is installed with the same or slightly improved performance as a conventional biological treatment device that treats only kitchen wastewater, It can meet the effluent standards set forth, can greatly reduce the initial cost and running cost for installing the sewage treatment system, and has the great effect that the installation space of the biological treatment equipment is almost the same as when treating only kitchen effluent. There is.

  In addition, even if an existing building is equipped with a biochemical treatment system as a kitchen drainage abatement equipment, if the treatment capacity is not sufficient, solidified crushed solids can be used. It is difficult to process in biological treatment equipment at the same time without liquid separation, and there is a limit to enhancing the treatment capacity of biological treatment equipment, and mixed wastewater containing pulverized solids and kitchen wastewater are treated simultaneously. It is difficult to do. In the soot treatment system according to each of the inventions according to claims 2 to 5, when there is a concern that the existing biological treatment apparatus or the treatment capacity is insufficient, some of the biological treatment apparatus is used to improve the treatment capacity. By adding work to carry out augmentation work, this will be used as a biological treatment device for the dredging system, and a grinder will be installed in the kitchen, and a water supply, solid-liquid separator, and separation liquid transfer pipe will be installed at low cost. There is an effect that a processing system can be realized.

  In general, kitchen drainage pipes are combined with water drainage when washing utensils and dishes in addition to drainage of water used for cooking such as food washing, and the amount of drainage is higher than drainage pipes of other systems. Many. In large-scale buildings, the tendency is particularly strong, and when the amount of drainage flowing down the kitchen drainage pipe is large, the ground solids are accumulated in the kitchen drainage pipe even if the crushed straw is merged into the kitchen drainage pipe as it is. It is unlikely that In the soot treatment system according to the invention described in claim 3, the pulverized crushed soot is joined as it is to the kitchen drain pipe by the soot transfer pipe, and a solid-liquid separator is installed at the end where each kitchen drain pipe joins one. Thus, since the pulverized solid is separated into solid and liquid, there is an effect that the pulverized solid in the entire building can be taken out only by performing the operation of taking out the pulverized solid with one solid-liquid separator. . When the cleaning staff of the building facility performs the clogging work of the pulverized solid, the workload of the cleaning staff is greatly reduced.

  According to the soot treatment system according to the fourth aspect of the present invention, since the pulverized solid separated by the solid-liquid separator can be dried by the dryer, the weight and volume of the pulverized solid are further reduced. It is possible to reduce the transportation work by human power, the cost of the transport vehicle, and the environmental load. In addition, even when pulverized solids are used as raw materials for fermentation treatment such as methane in a bio plant using pulverized solids as raw materials, the water-to-water ratio is greatly reduced by the drying process using a dryer. The temperature drop in the fermenter can be suppressed with smaller fluctuations, and there is also an effect that more efficient processing can be performed.

  In a fermentation process such as methane in a bio plant, the input straw is first liquefied in a fermenter and then methane-fermented with a methane-producing fungus to produce methane. According to the koji processing system according to the invention of claim 5, since the pulverized solid separated by the solid-liquid separator can be solubilized by the solubilizer, the pulverized solid is contained in the fermenter. Since there is no need to liquefy, methane can be efficiently produced in a shorter time, that is, there is an effect that a soot that can be easily used in a bioplant can be provided.

Embodiment 1 FIG.
FIG. 1 is a flowchart of the soot processing system in the first embodiment. The soot treatment system according to the first embodiment includes a kitchen drain pipe 1 installed in a building, pulverizers 2A and 2B installed in a plurality of locations in the building and pulverizing the introduced soot, and the pulverizer 2A. , 2B for supplying water to the water feeders 3A, 3B, and the solid-liquid separator 4A for introducing the mixed waste water pulverized by the pulverizers 2A, 2B into a pulverized solid and a separated liquid. , 4B and separated liquid transfer pipes 5A, 5B for transferring the separated liquid from the solid-liquid separators 4A, 4B to the kitchen drain pipe 1 of the respective systems. FIG. 1 shows a bag processing system for processing bags generated from two commercial kitchens at a distance in a building.

  The kitchen drainage pipe 1 joins the kitchen drainage pipes 1A and 1B to which the kitchen drainage generated in each commercial kitchen merges, and the kitchen drainage from each kitchen drainage pipe 1A and 1B to drain outside the building such as sewers. It comprises a kitchen drain pipe 1F. Usually, one commercial kitchen is provided with a plurality of sink sinks. The sink sink is equipped with a faucet and hot water tap, so that employees working in the kitchen can wash water and hot water when washing ingredients, throwing away the broth, and washing utensils and dishes. Drainage occurs as a result of using. Drainage generated from each sink in the commercial kitchen is joined to the kitchen drainage pipes 1A and 1B that are responsible for drainage of each commercial kitchen from the sink sink drain via the appliance drainage pipe. The waste water flowing through the kitchen drain pipes 1A and 1B is generally called kitchen waste water.

  In each commercial kitchen, pulverizers 2A and 2B for pulverizing the pestle, water supply units 3A and 3B for supplying water to the pulverizer, and the mixed waste water of the pulverized culm and water are separated into solid and separated liquids. Solid-liquid separators 4A and 4B and separation liquid transfer pipes 5A and 5B for transferring the separation liquid to the kitchen drain pipe are provided as a set for each commercial kitchen. Since the concentration of the separation liquid transferred from the solid-liquid separators 4A and 4B by the separation liquid transfer pipes 5A and 5B is high, the appliance drain pipe of the sink sink is connected upstream, and the kitchen in the kitchen drain pipes 1A and 1B. It is desirable to join the separated liquid at a position where the amount of drainage water increases. That is, it is desirable to connect the separation liquid transfer pipes 5A and 5B to the downstream side of the kitchen drain pipes 1A and 1B as much as possible.

  The pulverizers 2A and 2B can be a pulverizer that is normally used in a cocoon treatment system for apartment houses, but basically may have any structure as long as the pulverizer can be finely pulverized. . In the pulverization method of the pulverizers 2A and 2B, a disk in which protrusions made of stainless steel or the like are attached to a surface near the circumference in a cylindrical pulverization chamber is rotated at high speed by the power of an electric motor or the like, so that In addition to the hammer mill method for pulverizing the introduced soot, the cutter mill method in which the pulverizing blade rotates at high speed in the pulverization chamber to smash the soot, there is a chain mill method. The pulverizers 2A and 2B are connected so that the inlet at the upper side of the pulverization chamber is directly connected to the drain outlet of the sink sink, the drainage port through which the mixed slag and water are discharged from the pulverization chamber, and the solid-liquid separators 4A and 4B. It arrange | positions so that it may connect with the inlet of this by piping. However, the present invention is not limited to installing in the sink sink, and it may be configured such that a charging port is provided at the bottom of a cone or pyramid-shaped tank dedicated to dredging and the charging ports of the crushers 2A and 2B are directly connected thereto. Good.

  The operation method of the pulverizers 2A and 2B includes, for example, a method in which a hand switch or a foot switch is pressed and operated, or after the pestle is input from the input port of the pulverizers 2A and 2B, the input port is covered with an upper lid. There is a type in which the switches of the pulverizers 2A and 2B are automatically turned on, but any system may be used. As for water supply to the pulverizers 2A and 2B, which is necessary for washing the pulverization chamber or flowing the pulverized slag to the solid-liquid separators 4A and 4B, for example, drinking, food and tableware provided in the sink sink -Water supply pipes connected to the pulverization chambers of the crushers 2A and 2B by manually opening a water faucet (a kind of water supply 3A, 3B) used mainly for cleaning kitchen appliances, etc. There is a method of automatically supplying water with the operation of the pulverizers 2A and 2B by an automatic opening / closing valve such as a solenoid valve assembled in the pipe.

  Solid-liquid separators 4A and 4B are equipped with a flat screen, introduced mixed waste water of slag and water crushed from above the flat screen, and are separated from the flat screen by gravity to separate the solid and liquid, rotating A type in which the mixed waste water is allowed to flow into a cylindrical container and the separated liquid is centrifuged is applicable.

  Further, the solid-liquid separators 4A and 4B are solid-liquid separators comprising a rotating container having a cylindrical shape and a slit-shaped screen on the outer periphery, and an outer container covering the rotating container. It is also possible to apply a solid-liquid separator that introduces the mixed waste water and passes the separated water from the slit-shaped screen to the inside of the rotating container. In this type of solid-liquid separator, a protrusion is provided on the outer periphery of the rotating container to scrape the pulverized solid that accumulates on the inner wall of the outer container. The protrusion causes the pulverized solid to be above the mixing drainage surface in the outer container. Is discharged to the outside of the solid-liquid separator. And the discharge port is connected with the storage container by the pipe line etc., and the crushing solid substance discharged | emitted from the discharge port is stored by the storage container.

Next, the operation of the soot processing system of Embodiment 1 will be described.
The soot to be treated is introduced from the inlets of the pulverizers 2A and 2B installed in the commercial kitchen, and the pulverizers 2A and 2B into which the soot is introduced are operated. During the operation, water is supplied from the water supply units 3A and 3B into the pulverization chambers of the pulverizers 2A and 2B. At this time, the pulverized soot and water are mixed in the pulverizing chambers of the pulverizers 2A and 2B, and the mixed waste water is forced to the solid-liquid separators 4A and 4B by the rotational force in the pulverizing chambers of the pulverizers 2A and 2B. Is sent to. In the solid-liquid separators 4A and 4B, the mixed waste water from the pulverizers 2A and 2B is subjected to solid-liquid separation into a pulverized solid matter and a separated liquid which are solid contents in the soot. The pulverized solid after the solid-liquid separation is stored in the solid-liquid separators 4A and 4B, or transferred to and stored in a storage container installed closest to the solid-liquid separators 4A and 4B. The stored pulverized solid matter is periodically carried out of the storage container by an employee of a commercial kitchen or a cleaning staff of a building facility.

  The separated liquid separated from the pulverized solids by the solid-liquid separators 4A and 4B is transferred to the nearest kitchen drain pipes 1A and 1B through the separated liquid transfer pipes 5A and 5B. In these kitchen drain pipes 1A and 1B, the kitchen drainage from the sink sink of the commercial kitchen that the kitchen drain pipes 1A and 1B are responsible for flows, and the separated liquid joins the kitchen drainage. The kitchen drainage pipes 1A and 1B are joined together by the kitchen water distribution pipe 1F, transferred to the lowest floor of the building, and discharged outside the building such as a sewer.

  In the basket processing system of the first embodiment, as shown in FIG. 1, an example of application in two commercial kitchens separated from each other in the building has been shown. Of course, it can be applied to a building in a remote location. In that case, since the kitchen drain pipe is always arranged in each commercial kitchen, in addition to that, the crusher, the water feeder, the solid-liquid separator, and the separated liquid transfer pipe are arranged as in the case of FIG. Good. Also, in commercial buildings where the distance between commercial kitchens is close, there are many cases where a kitchen drainage pipe is also used, so a set of crusher, water supply, solid-liquid separator, and separated liquid transfer pipe is also installed. It may be shared in both commercial kitchens.

As described above, according to the soot processing system of the first embodiment, the following numerous effects can be obtained.
(1) The separation liquid is discharged into the kitchen drain pipes 1A and 1B by the separation liquid transfer pipes 5A and 5B, so that the separation liquid can be used even in a building that has an existing commercial kitchen and is provided with the kitchen drain pipe. There is no need to install a new pipe for discharging the wastewater outside the system, and the installation cost of the soot treatment system can be reduced.
(2) The slag is pulverized by the pulverizers 2A and 2B, and the mixed waste water of the pulverized slag and water is solid-liquid separated into the pulverized solids and the separated liquid by the solid-liquid separators 4A and 4B. The crushed solid matter can be taken out by discharging to the drain pipes 1A and 1B. As a result, compared to the original cocoon, the pulverized solids can remove some moisture and reduce the weight, and by pulverizing the cocoons, the gaps when individual cocoons are collected are reduced and packed. The overall volume of the bag can be reduced.
(3) It is possible to significantly reduce the transportation work load due to human power from the location where the cocoon occurs such as a kitchen to the temporary storage location in the facility. In addition, the transportation cost from the temporary storage place to the waste disposal site can be reduced, and further, the amount of fuel used by the transport vehicle can be reduced, thereby contributing to the reduction of environmental burden.
(4) Since the mixed waste water of pulverized soot and water is solid-liquid separated, the pulverized solid after the solid-liquid separation can be carried out without being treated with aerobic microorganisms or anaerobic microorganisms or incineration. In the state where the energy held by the organic matter in the basket is maintained almost as it is, the pulverized solid matter with less moisture can be taken out.
(5) This pulverized solid has a wider application than sludge. For example, methane can be extracted by methane fermentation treatment, hydrogen can be extracted by hydrogen fermentation treatment, or biogas can be extracted by so-called bioplants. Therefore, the energy possessed by the bag can be used effectively.
(6) Since the pulverized solids carried out from the solid-liquid separators 4A and 4B have a small amount of water, the rate of decrease in temperature in the fermenter during the fermentation process such as methane is reduced, and a more stable fermentation process such as methane is performed. It becomes possible to carry out efficiently at low cost.
(7) The soot is pulverized by the pulverizers 2A and 2B, the pulverized solid is removed by the solid-liquid separators 4A and 4B, and only the separated liquid is drained from the separated liquid transfer pipes 5A and 5B to the kitchen drain pipes 1A and 1B. Therefore, the pulverized solid does not flow into the separated liquid transfer pipes 5A and 5B and the kitchen drain pipes 1A and 1B. For this reason, in the horizontal piping part of the kitchen drain pipes 1A and 1B, even when the drainage flow rate of the kitchen drainage is small and the solid material transport capacity is reduced, the pulverized solid matter may stay at the bottom of the horizontal piping part. There is no.
(8) When the worker of the building facility collects the pulverized solid from the solid-liquid separator 4, from the viewpoint of reducing the load on the worker, the kitchen drainage combined with the kitchen drainage pipes 1A and 1B. The configuration in which one large solid-liquid separator is installed in the pipe 1F is more efficient in recovering the pulverized solid matter. Usually, the labor cost of a worker of a building facility must be borne by each business operator operating a store (such as a restaurant) having a commercial kitchen in the building. Currently, installation of a dredging treatment system is not obligated by laws and regulations. In particular, in the case of buildings where many businesses that have commercial kitchens such as restaurant buildings and complex buildings are operating in the building, businesses that want to select a convenience and adopt a coffee processing system It is anticipated that there will be a mix of operators and operators who think that the dredging system is unnecessary because of the cost increase, so install a large solid-liquid separator and let the building facility workers perform maintenance. It is difficult to realize a form in which each operator bears installation costs and maintenance costs. In the soot processing system according to the first embodiment, each operator can select whether or not to use the soot processing system, and it is possible for an employee to carry out the pulverized solid matter and to reduce the running cost. .

Embodiment 2. FIG.
FIG. 2 is a flowchart of the cocoon processing system according to the second embodiment. The same parts as those in FIG. In the second embodiment, the biological treatment device 12 is provided on the downstream side of the kitchen drain pipe 1F where the kitchen drain pipes 1A and 1B of the commercial kitchens in the first embodiment are combined. This is greatly different from the first form.

  FIG. 3 shows an example of the biological treatment apparatus 12 that can be applied to the cocoon treatment system according to the second embodiment. This biological treatment apparatus 12 purifies the mixed wastewater from the storage tank 13 which stores the kitchen wastewater from each commercial kitchen to be treated and the mixed wastewater of the separated liquid flowing into the kitchen drainage pipe 1F and stores them. An aeration tank 14 is provided, and a settling tank 150 for precipitating the mixed waste water from the aeration tank 14 is provided. The mixed waste water in the storage tank 13 is transferred to the aeration tank 14 by the transfer means 16. The mixed waste water in the aeration tank 14 is transferred to the sedimentation tank 150 by the transfer pipe 17. Then, wastewater containing a large amount of sludge that settles at the bottom of the sedimentation tank 150 (hereinafter, such wastewater containing a large amount of sludge is referred to as sludge drainage) is returned to the aeration tank 14 by the sludge return means 18. is there.

  That is, in the soot treatment system according to the second embodiment, a conventional activated sludge method using aerobic microorganisms is applied to the biological treatment apparatus 12, and in particular, sludge wastewater that has been subjected to precipitation treatment in the settling tank 150 is returned to the sludge return means 18. Therefore, the standard activated sludge method for returning to the aeration tank 14 is applied.

  More specifically, the kitchen drain pipe 1F is provided with a screen 20 for circulating mixed waste water from each commercial kitchen. This screen 20 is provided for pretreatment to remove relatively large and different suspended substances, ie, foreign substances, contained in the mixed wastewater (mainly kitchen wastewater). The structure of the screen 20 is not limited, and any structure can be applied as long as impurities in the mixed waste water can be removed. However, when the amount of contaminants in the mixed waste water is such that it can be decomposed by the biological treatment device 12, it is not necessary to install the screen 20.

  The storage tank 13 temporarily stores the mixed waste water that flows in from the kitchen drain pipe 1F, and the storage tank 13 is provided with an air diffuser 210 that discharges coarse bubbles into the mixed waste water. The air diffuser 210 includes an air diffuser 220 disposed on the bottom surface on one side wall in the storage tank 13, a blower 23 disposed outside the reservoir 13, and an air supply pipe 24 connecting the air diffuser 220 and the blower 23. It is constituted by. Then, coarse bubbles are discharged into the mixed waste water from the diffuser tube 220 on the bottom surface on one side wall in the storage tank 13, and the buoyancy of the coarse bubbles is given to the mixed waste water above the diffuser tube 220 to generate an upward flow. In addition, a stirring flow is generated in the mixed waste water in the storage tank 13 by generating a downward flow in the mixed waste water on the other side wall side where the diffuser tube 220 is not provided. This prevents the mixed wastewater stored in the storage tank 13 from becoming anaerobic.

  The aeration tank 14 purifies the mixed waste water by aerobic treatment, that is, the organic matter in the sewage transferred from the storage tank 13 by the transfer means 16 is returned from the mixed waste water or the precipitation tank 150 in the aeration tank 14. It is supposed to be decomposed by aerobic microorganisms contained in sludge wastewater. The aeration tank 14 is provided with an air diffuser 25 for ejecting fine bubbles from the entire bottom surface of the tank into the mixed waste water. The air diffuser 25 includes an air diffuser pipe 26 disposed on the entire bottom surface of the aeration tank 14, a blower 27 disposed outside the aeration tank 14, and an air supply pipe 28 connecting the air diffuser pipe 26 and the blower 27. It is.

  In addition, since the coarse bubbles have a characteristic that they are difficult to dissolve in the mixed wastewater, and when the coarse bubbles rise in the mixed wastewater, they have a characteristic of imparting buoyancy to the surrounding mixed wastewater. It is particularly suitable when it is necessary to generate an upward flow in the mixed waste water. On the other hand, the fine bubbles have the property of being easily dissolved in the mixed wastewater, but the bubbles are dissolved and disappeared while rising in the mixed wastewater, so it is difficult to give a large buoyancy to the surrounding mixed wastewater. For this reason, it is particularly suitable when it is necessary to provide oxygen to the aerobic microorganisms by dissolving the air in the mixed waste water as in the aeration tank 14.

  Since the storage tank 13 and the aeration tank 14 are constantly diffused by the diffuser 210 and the diffuser 25, respectively, the diffused air is generated in the storage tank 13 and the aeration tank 14 in each tank. Exhaust means (not shown) is provided for reducing the odor of the gas to be discharged out of the system. The exhaust means includes an exhaust branch pipe that is started up from the storage tank 13 and the aeration tank 14, a single exhaust main pipe that joins the exhaust branch pipes, and the exhaust main pipe in order. The mist separator, the exhaust fan, and the deodorizing tower are provided.

  The sedimentation tank 150 is a water tank having a hopper-like bottom surface, and separates the mixed wastewater flowing from the aeration tank 14 into upper supernatant water and lower layer sludge drainage. Contains aerobic microorganisms. An overflow weir 29 is provided at a predetermined position on the side of the settling tank 150 opposite to the side to which the transfer pipe 17 is connected. Further, on the outside of the sedimentation tank 150, a supernatant water transfer pipe 30 for discharging the supernatant water overflowed from the overflow weir 29 to the outside of the system is disposed. In such a sedimentation tank 150, the level of the supernatant water rises every time mixed wastewater flows from the transfer pipe 17, and the supernatant water flows over the overflow weir 29 and flows into the supernatant water transfer pipe 30. If necessary, a discharge water tank (not shown) may be installed at the end of the supernatant water transfer pipe 30 and the supernatant water may be temporarily stored in the discharge water tank. This configuration will transfer the supernatant water stored in the discharge water tank out of the system by a pump and a transfer pipe, but it is suitable when the amount of discharged water is regulated when the supernatant water is discharged to a public sewer, for example. .

  The storage tank 13, the aeration tank 14, and the sedimentation tank 150 can be a body water tank that uses an underfloor pit in a building or an on-floor installation type water tank that uses a space above the floor. In the case of a body water tank, it is preferable because the space on the floor can be utilized for other purposes, but it is necessary to form a waterproof layer by lining such as epoxy resin on the inner surface of the water tank. In the case of a floor-mounted water tank, the storage tank 13 can be formed of a synthetic resin such as FRP or polypropylene, a metal such as a steel plate or stainless steel, or concrete.

  The transfer means 16 for transferring the mixed waste water in the storage tank 13 to the aeration tank 14 includes a transfer pump 160 installed in the mixed waste water in the storage tank 13 and one end connected to the transfer pump 160 and the other end to the aeration tank. 14, a transfer pipe 161 opened to 14, and a measuring tank 162 disposed in the middle of the transfer pipe 161. The measuring tank 162 has a structure in which the transfer amount of the mixed waste water is controlled to be quantitative by a weir provided therein. And the excess mixed waste_water | drain which flowed out from the weir in the measurement tank 162 is made to return to the storage tank 13 via the return pipe which is not shown in figure.

  Such a transfer means 16 is not limited to the above configuration. For example, although the transfer pump 160 is a submersible pump, a configuration in which a foot valve is provided instead of the submersible pump by disposing it on the transfer pipe 161 on the primary side of the metering tank 162 as an onshore pump. Further, instead of providing the measuring tank 162 in the transfer pipe 161, a bypass pipe connecting the middle of the transfer pipe 161 and the storage tank 13 is provided, and a flow meter is provided in the transfer pipe 161. In addition, a control valve such as an electric valve, a pneumatic valve, or a hydraulic valve may be provided to control the control valve so that the measurement value of the flow meter maintains a predetermined flow rate.

  The transfer pipe 17 is configured such that the aeration tank 14 and the sedimentation tank 150 communicate with each other through a pipe. However, the structure of the transfer pipe 17 is not limited as long as the mixed waste water in the aeration tank 14 can be reliably transferred to the settling tank 150. For example, the transfer pipe 17 has a structure that allows mixed wastewater to naturally flow out from the aeration tank 14 to the sedimentation tank 150 by a weir, and a structure that allows mixed wastewater to naturally flow out from the aeration tank 14 to the sedimentation tank 150 through an opening. Can do. In addition, the mixed waste water in the aeration tank 14 can be forcibly pumped to the sedimentation tank 150 by a pump and a transfer pipe. Thus, it is necessary to be able to control the transfer amount by turning the pump ON / OFF. Furthermore, especially when the mixed wastewater is pumped to the sedimentation tank 150 by a pump, or when the flow rate of the mixed wastewater flowing into the sedimentation tank 150 is large even in a structure that naturally flows out, the mixed wastewater that flows into the lower layer in the precipitation tank 150 A part of the sludge drainage is rolled up to the upper supernatant water and stirred, which may cause a problem in the precipitation process. In this case, it is preferable to install a baffle or a center well having a role of attenuating the flow rate of the mixed wastewater flowing into the opening on the settling tank 150 side of the transfer pipe 17.

  The sludge return means 18 for returning the sludge drainage in the settling tank 150 to the aeration tank 14 is connected to the return pump 180 disposed at the bottom of the settling tank 150, one end connected to the return pump 180, and the other end to the aeration tank 14. The sludge return pipe 181 is opened, and the measuring tank 182 is provided in the middle of the sludge return pipe 181. As in the case of the transfer means 16, the measuring tank 182 controls the transfer amount by a weir provided therein, and excess sludge drainage flowing out from the weir in the measuring tank 182 is sent to the sedimentation tank 150 via a return pipe (not shown). As a structure to return. The sludge return means 18 is not limited to this configuration, and sludge wastewater may be returned to the aeration tank 14 by an air lift instead of the return pump 180.

  The diffuser pipe 26 of the aeration tank 14 can be formed, for example, in a cylindrical shape or a plate shape from a material obtained by solidifying granular resin so that a gap remains. However, the material and structure of these air diffusers 26 are not limited as long as they can discharge relatively fine bubbles into the mixed waste water. For example, the diffuser pipe 26 has a structure in which a rubber having a large number of small holes is wound around the outer periphery of a pipe having a large number of relatively large holes, or a structure having a circular disk shape and a large number of small holes in the circumferential portion. Disc diffuser. The air diffuser 26 may be a bag-like air diffuser, a saran-wrapped air diffuser, a box aerator, a shear fuser, or the like.

  The storage tank 13 has a substantially flat bottom surface, and a concave pump pot (not shown) is provided on a part of the bottom, and the transfer pump 160 of the transfer means 16 is disposed in the pump pot. is doing. The bottom surface of the storage tank 13 is given a predetermined gradient that decreases toward the pump kettle so that the solid matter in the mixed waste water does not stay on the bottom surface of the storage tank 13. The predetermined gradient of the bottom surface of the storage tank 13 is preferably about 10 to 15 degrees.

  The settling tank 150 side of the transfer pipe 17 is opened at a predetermined height position. The overflow weir 29 is provided on the side surface opposite to the side surface where the transfer pipe 17 opens at a height position where the supernatant water overflows at the set water level, and the supernatant water transfer pipe 30 is the height of the overflow weir 29. It is provided corresponding to the position. A concave pump pot (not shown) is provided at the corner of the bottom of the settling tank 15, and the return pump 180 of the return means 18 is disposed in the pump pot.

Next, the operation of the biological treatment apparatus 12 in the second embodiment will be described. In addition, since the operation | movement of the cocoon treatment system except the biological treatment apparatus 12 in Embodiment 2 is performed similarly to the said Embodiment 1, the operation | movement description is abbreviate | omitted.
The kitchen wastewater from each commercial kitchen and the separated liquid from the solid-liquid separators 4A and 4B merge at the kitchen drainage pipe 1F, and the mixed wastewater flows into the storage tank 13, while the screen 20 is pretreated. Remove impurities in the mixed waste water. The mixed waste water that has passed through the screen 20 flows into the storage tank 13 and is temporarily stored. In the storage tank 13, the air diffuser 210 ejects air from the air diffuser tube 220 into the sewage, whereby the mixed waste water is agitated to prevent anaerobic formation.

  The mixed waste water in the storage tank 13 is transferred from the transfer pipe 161 to the aeration tank 14 by operating the transfer pump 160 of the transfer means 16. At this time, the mixed waste water is adjusted in flow rate by the measuring tank 162 of the transfer means 16 and transferred to the aeration tank 14 as a fixed amount. At the same time, sludge drainage is returned to the aeration tank 14 through the sludge return pipe 181 from the settling tank 150 and mixed with the mixed wastewater in the aeration tank 14. Also at this time, the sludge returning means 18 adjusts the flow rate of the sludge drainage by the measuring tank 182 and returns it to the aeration tank 14 in a fixed amount. Sludge drainage contains a large amount of aerobic microorganisms, but the activity of the aerobic microorganisms is reduced and the adsorption / decomposition ability of organic matter is greatly reduced. However, in the aeration tank 14, the air diffuser 25 constantly spouts air from the diffuser pipe 26 into the mixed wastewater (mixed wastewater from the storage tank 13 and sludge wastewater from the settling tank 15). The aerobic microorganisms are reactivated and become capable of adsorbing and decomposing organic matter, and decomposing the organic matter already adsorbed by itself. Next, the aerobic microorganisms adsorb organic substances in the mixed waste water, and further start decomposition to perform aerobic treatment.

  The mixed waste water aerobically treated in the aeration tank 14 flows through the transfer pipe 17 and overflows to the settling tank 150. The flow rate of the mixed waste water flowing into the sedimentation tank 150 is the same as the flow rate of the mixed waste water flowing into the aeration tank 14 from the storage tank 13. In the settling tank 150, the mixed waste water is allowed to stand, and is separated into the upper supernatant water and the lower sludge waste water. The supernatant water overflows the overflow weir 29 and is discharged out of the building such as a sewer as treated water through the supernatant water transfer pipe 30. The amount of the supernatant water flowing out through the supernatant water transfer pipe 30 is returned from the precipitation tank 150 to the aeration tank 14 from the amount of mixed waste water flowing from the aeration tank 14 through the transfer pipe 17 into the precipitation tank 150. The amount of sludge drainage is subtracted.

  In addition, although the biological treatment apparatus 12 in this Embodiment 2 applied the waste water treatment system by the activated sludge method, it is not necessarily limited to this, The waste water treatment by the contact aeration method using the same aerobic microorganism, An aerobic filter method and a long-time aeration method are also applicable. Also, anaerobic treatment with anaerobic microorganisms can be applied, and multi-stage treatment combining the aerobic treatment and anaerobic treatment is also applicable. Furthermore, the mixed waste water of the kitchen waste water and the separated liquid may be further purified by performing filtration treatment or the like on the treated water purified by these treatments, and may be reused for toilet flushing water or water spraying.

  As described above, in the soot treatment system according to Embodiment 2, the separation liquid after separating the pulverized solids by the solid-liquid separators 4A and 4B is purified by the biological treatment device 12 together with the kitchen waste water. Thus, in addition to the effects shown in the first embodiment, the following effects can be obtained.

  In the case of a cocoon treatment system in which the biological treatment device 12 purifies the mixed wastewater of pulverized wastewater and water together with the kitchen wastewater without solid-liquid separation, the biological treatment device 12 has a mixed wastewater with a very high concentration and a relatively high amount. Because it is necessary to purify the concentration of kitchen wastewater at the same time, it is purified to a water quality that meets the emission standard values stipulated by laws and regulations in a relatively simple purification process such as the standard activated sludge method shown in FIG. It is difficult to do.

  In contrast, in the koji processing system according to the second embodiment, pulverized solids are separated by the solid-liquid separators 4A and 4B. Since it is a mixed wastewater with a slightly higher concentration separated by solid-liquid separation but a small amount compared to kitchen wastewater, it is a mixed wastewater with a slightly higher concentration than normal kitchen wastewater, so standard activated sludge method etc. Even with this relatively simple purification treatment, there is a great effect that it is possible to sufficiently purify the water quality to meet the emission standard value stipulated by laws and regulations.

  Further, in the soot treatment system in the second embodiment, since a relatively simple purification method can be applied to the biological treatment apparatus 12, the initial cost and running cost for installing the soot treatment system can be greatly reduced, The installation space of the processing device 12 has a great effect that it is almost the same as when only the kitchen wastewater is processed.

  In addition, even if an existing building has already been installed with a biochemical treatment system as a kitchen drainage abatement facility, ground solids should be used if there is not enough capacity. It is difficult to process in biological treatment equipment at the same time without solid-liquid separation, and there is a limit in enhancing the treatment capacity of biological treatment equipment, and mixed wastewater containing pulverized solids and kitchen wastewater are simultaneously used. It was difficult to process.

  On the other hand, in the dredging treatment system according to the second embodiment, when there is a concern that the existing biological treatment apparatus or the processing capacity will be insufficient, a slight enhancement work of the biological treatment apparatus is performed to improve the processing capacity. The work to be performed is added, and this is used as the biological treatment device 12 of the dredging system, and further, the crushers 2A and 2B are installed in the kitchen, the water feeders 3A and 3B, the solid-liquid separators 4A and 4B, and the separated liquid transfer pipe 5A. , 5B can be provided at a low cost.

Embodiment 3 FIG.
FIG. 4 is a flowchart relating to the biological treatment apparatus in the cocoon treatment system according to the third embodiment. The same or corresponding parts as in FIG. The biological treatment apparatus 12 of the third embodiment is applied to the cocoon treatment system of the second embodiment. In the third embodiment, the biological treatment apparatus 12 of the second embodiment (FIG. 3) stores the diffusion tube 22 in the storage tank 13 so that the entire surface can be aerated, and stores the bottom surface of the sedimentation tank 15. The point which made it the same planar shape as the tank 13 and the aeration tank 14, the point which returned the sludge drainage in the settling tank 15 to the storage tank 13, and spouts bubbles to the bottom face in the settling tank 15. This is largely different from the biological treatment apparatus 12 of the second embodiment in that a diffusion tube 52 capable of performing the above is provided.

  In the third embodiment, the plurality of air diffusers 22 in the air diffuser 21 of the storage tank 13 have the same structure as the air diffuser pipe 26 of the aeration tank 14 and can discharge relatively fine bubbles. Yes. The air diffuser 22 is arranged at regular intervals over the entire bottom surface except for the pump kettle so that the kitchen waste water in the storage tank 13 and the mixed waste water of the separation liquid can be aerated. The air supply pipe 24 of the air diffuser 21 is connected to each air diffuser 22 by being lowered from the blower 23 to the center of the row of air diffusers 22. These air diffusers 22 are arranged at a predetermined height so that the water pressure applied to each air diffuser 22 is approximately the same, and bubbles are ejected from each air diffuser 22 evenly. The arrangement position of the diffuser pipe 22 in the storage tank 13 and the piping method of the air supply pipe 24 may be any configuration as long as air can be supplied from the entire bottom surface of the storage tank 13, that is, the entire surface can be aerated. May be.

  The bottom surface of the sedimentation tank 15 is provided with a predetermined gradient that decreases from each side surface toward the pump kettle so that sludge in the drainage does not stay on the bottom surface. The predetermined gradient is preferably about 10 to 15 degrees as in the case of the storage tank 13. When it is set as a body water tank like the storage tank 13 etc., the direction which makes the bottom face shape of a water tank flat can suppress the height of a water tank lower than making it a hopper shape, and since it is a square, a water tank There is merit that it is easy to take large bottom area and is easy to build. However, since the bottom surface shape of the sedimentation tank 15 is a flat surface, there is a problem that the sludge drainage tends to stay on the bottom surface when the inflowing mixed wastewater is settled. The sludge drainage of the portion that has become difficult to be returned to the storage tank 13 by the return pump 180 due to being deviated and accumulated becomes anaerobic and generates septic gas and the like inside. Sludge in the sludge drainage, which has a lighter specific gravity than water, floats on the supernatant water surface and changes to scum.

  As a countermeasure for preventing this problem, a diffuser pipe 52 is disposed in the sedimentation tank 15 so that bubbles are ejected toward the bottom surface, and an air supply pipe 53 branched from the air supply pipe 28 is connected to the diffuser pipe 52. Thus, it is possible to agitate the supernatant water and sludge drainage in the sedimentation tank 15. That is, during normal times (such as a time zone in which the amount of mixed wastewater flowing into the storage tank 13 is large), the open / close valve 54 provided in the air supply pipe 53 is closed, and bubbles are not ejected from the air diffusion pipe 52. The biological treatment apparatus 12 performs biological treatment of the mixed waste water. Then, at a time when the amount of mixed wastewater flowing into the storage tank 13 is small, such as at night, the transfer pump 160 is stopped to stop the mixed wastewater from flowing into the aeration tank 14, and the return pump 180 is activated to cause precipitation. After the supernatant water level in the tank 15 is lowered and air bubbles are ejected in the sedimentation tank 15, the mixed water of the supernatant water and sludge drainage does not overflow from the overflow weir 29 before opening and closing. The valve 54 is opened and air bubbles are ejected from the diffuser tube 52 toward the bottom surface to stir the supernatant water and the sludge drainage. In addition, if there is room in installation conditions, it is possible to apply a hopper-shaped water tank in place of the sedimentation tank 15 whose bottom surface is generally flat.

  On the other hand, the other end of the sludge return pipe 181 whose one end is connected to the sludge transfer pump 180 at the bottom of the settling tank 15 is opened in the storage tank 13 instead of the aeration tank 14. The lower layer sludge drainage is returned to the storage tank 13.

  Next, the operation of the biological treatment apparatus 12 in the third embodiment will be described. At the same time as the mixed waste water of the kitchen waste water and the separated liquid flows into the storage tank 13 from the kitchen drain pipe 1F through the screen 20, the sludge waste water in the settling tank 15 is operated in the sludge return pump 180 in the storage tank 13. Thus, it flows in through the sludge return pipe 181 and mixes with the mixed waste water stored in the storage tank 13. At this time, the sludge return means 18 adjusts the flow rate of the sludge drainage returned by the measuring tank 182 and returns it to the storage tank 13 in a fixed amount. Sludge drainage contains a large amount of aerobic microorganisms, but its activity is reduced, and the ability to adsorb and decompose organic substances is greatly reduced. However, in the storage tank 13, air is dissolved in the mixed wastewater by constantly ejecting fine bubbles from the diffuser pipe 22 of the diffuser 21 into the mixed wastewater. Aerobic microorganisms take in oxygen from the dissolved air, reactivate it, and become capable of adsorbing and decomposing organic matter, and decomposing the organic matter already adsorbed by itself. Next, the aerobic microorganisms adsorb organic substances in the mixed waste water, and further start decomposition to perform aerobic treatment.

  Thus, the mixed waste water aerobically treated in the storage tank 13 is transferred from the transfer pipe 161 to the aeration tank 14 by the operation of the transfer pump 160 of the transfer means 16. Also at this time, the transfer means 16 adjusts the flow rate of the mixed waste water by the measuring tank 162 and sequentially flows it to the aeration tank 14 as a fixed amount. In the aeration tank 14, the air diffuser 25 ejects fine bubbles from the air diffuser pipe 26 into the mixed waste water, and the aerobic microorganisms in the sludge of the mixed waste water decompose the adsorbed organic matter and continue the aerobic treatment. . Thereafter, the aerobically treated mixed waste water flows into the settling tank 15 through the transfer pipe 17. The flow rate of the mixed waste water flowing into the settling tank 15 is the same as the flow rate of the mixed waste water flowing into the aeration tank 14 from the storage tank 13.

  In the settling tank 15, the mixed waste water is allowed to stand and is separated into upper supernatant water and lower sludge waste water. The supernatant water overflows the overflow weir 29 and flows out of the system through the supernatant water transfer pipe 30. The amount of the supernatant water flowing out through the supernatant water transfer pipe 30 is returned from the precipitation tank 15 to the storage tank 13 from the amount of the mixed waste water flowing from the aeration tank 14 through the transfer pipe 17 into the precipitation tank 15. This is the amount after subtracting the return of sludge wastewater. The biological treatment apparatus 12 in the third embodiment performs the aerobic treatment by the processing flow as described above.

  As described above, in the dredging treatment system according to the third embodiment, the wastewater mixed with the separated liquid and the kitchen wastewater separated by the solid-liquid separators 4A and 4B is purified by the biological treatment apparatus 12 shown in FIG. By adopting such a configuration, in addition to the effects shown in the first and second embodiments, the following effects can be obtained.

  In the biological treatment apparatus 12 according to the third embodiment, an air diffuser 21 that ejects fine bubbles into the mixed waste water in the storage tank 13 is disposed in the storage tank 13, and sludge in which many aerobic microorganisms are present. Since the waste water is returned from the settling tank 15 to the storage tank 13 by the sludge return means 18, sludge that has an anaerobic tendency in the settling tank 15 can be reactivated in the storage tank 13. Therefore, the aerobic microorganisms in the reactivated sludge can adsorb and decompose the organic matter in the mixed wastewater in the storage tank 13, and there is a great effect that the aerobic treatment can be performed in the storage tank 13.

  Moreover, in the biological treatment apparatus 12 of this Embodiment 3, while mixing wastewater and sludge wastewater are made to contact in the storage tank 13, those mixed wastewater is diffused by the aeration apparatus 21, Therefore, Aerobic microorganisms in sludge are contained. Adsorption time for adsorbing organic matter in the mixed waste water can be secured. Moreover, since the adsorbed organic matter can be decomposed, part of the decomposition time can be secured. Further, in the aeration tank 14, the mixed wastewater has only to be retained for a minimum decomposition time until the aerobic microorganisms decompose all the organic substances, so that the capacity of the aeration tank 14 can be greatly reduced. is there. On the other hand, if the capacity of the aeration tank 14 is made the same as the conventional one, there is a great effect that the processing capacity for decomposing organic substances can be greatly improved.

  Furthermore, since the biological treatment apparatus 12 of this Embodiment 3 performs aerobic treatment in the storage tank 13, generation | occurrence | production of septic gas, such as hydrogen sulfide, when the mixed waste_water | drain in the storage tank 13 becomes anaerobic is large. There is a great effect that it can be reduced and the problem of odor caused by it can be solved. In addition, since the generation of spoilage gas can be greatly reduced, it is possible to greatly suppress deterioration of the lining in the storage tank 13 and deterioration of the transfer pump 160 due to this, and the frequency of repair of the lining and replacement of the transfer pump 160 can be reduced. There is a great effect that it can be greatly reduced and the labor and cost of repair and replacement can be greatly reduced. In addition, the normal lining material can be used instead of septic gas, and the transfer pump 160 can be a general specification with low corrosion resistance, so that the initial cost of system construction can be greatly reduced. effective. And since the generation of septic gas can be greatly reduced, the odor of the exhaust gas flowing out from the system is reduced, so there is an effect that the deodorizing device such as a deodorizing tower can be made smaller than before and the initial cost can be reduced. . In addition, since the amount of activated carbon, deodorizing bacteria, etc. that need to be replaced periodically is reduced, there is a great effect that the running cost can be greatly reduced.

  And in the biological treatment apparatus 12 of this Embodiment 3, since it carries out the aerobic process of mixed waste water in the storage tank 13, it becomes possible to adsorb | suck the oil component in mixed waste water to an aerobic microorganism, and oil content is a storage tank. Adhering to the 13 side surfaces can be greatly reduced. As a result, the number of cleanings of the storage tank 13 is greatly reduced, and the labor cost for cleaning and the cost of disposing of the deposits as industrial waste are greatly reduced. In addition, since the mixed waste water is subjected to aerobic treatment in the storage tank 13, it is reactivated in order to reactivate the aerobic microorganisms in the sludge waste water returned from the precipitation tank 15 like a biological treatment apparatus equipped with a conventional precipitation tank. Even if an aerobic tank is not provided and aerobic treatment is not performed, the purification ability of the entire biological treatment apparatus can be made equivalent to that of a conventional biological treatment apparatus, and the installation area of the biological treatment apparatus can be reduced. .

Embodiment 4 FIG.
FIG. 5 is a flowchart regarding the biological treatment apparatus of the cocoon treatment system according to the fourth embodiment. The same or corresponding parts as those in FIG. The biological treatment apparatus 12 according to the fourth embodiment is applied to the cocoon treatment system according to the second embodiment. In the fourth embodiment, a re-aeration tank 31 is added to the biological treatment apparatus 12 of FIG. 3 that can be applied to the soot treatment system in the second embodiment, and further, a sedimentation tank is added to the re-aeration tank 31. The point which returned sludge waste water from 15 differs greatly from the biological treatment apparatus 12 in the said Embodiment 2. FIG.
The biological treatment apparatus 12 in the fourth embodiment sends the sludge drainage in the lower layer in the sedimentation tank 15 to the re-aeration tank 31 to reactivate the aerobic microorganisms in the sludge and further to a starvation state. The biosorption method returned to 13 is applied.

  The re-aeration tank 31 can have substantially the same structure and material as the aeration tank 14. The re-aeration tank 31 is provided with an aeration device 32 that ejects fine bubbles into the sludge drainage, similar to the aeration device 25 of the aeration tank 14. The air diffuser 32 includes a plurality of air diffusers 33 disposed at the bottom of the re-aeration tank 31, blowers 34 disposed outside the re-aeration tank 31, and air connected between the blower 34 and the air diffuser 33. A supply pipe 35 is used. The air diffusion pipe 33 is disposed on the entire bottom surface of the re-aeration tank 31 so that the entire sludge drainage in the re-aeration tank 31 is always aerated.

  Therefore, in the re-aeration tank 31, the aerobic microorganisms are reactivated by being diffused into the sludge drainage by the aeration device 32, and the organic matter in the sludge drainage is adsorbed and decomposed completely. Microorganisms become starved. In addition, since the aerobic microorganisms self-grow when decomposing organic matter in the aeration tank 14 and the re-aeration tank 31, the amount of sludge continues to increase as it is, and is periodically transported out as extra sludge. However, if further aeration is continued with respect to the aerobic microorganisms in the state of starvation, autooxidation (cannibalism) proceeds, so that the number of aerobic organic substances that have increased in the sludge drainage decreases. In this way, the sludge wastewater containing the starved aerobic microorganisms is returned through the return pipe 36 to the aeration tank 14 storing the mixed wastewater rich in organic matter and air. As a result, the organic matter in the aeration tank 14 is adsorbed and decomposed to promote the purification of the mixed waste water. During this time, according to the amount of the mixed wastewater transferred from the storage tank 13 to the aeration tank 14 by the transfer means 16, the supernatant water is discharged out of the system in the sedimentation tank 15, and a continuous purification process is performed.

  As described above, in the dredging treatment system in the fourth embodiment, the mixed waste water of the separated liquid and the kitchen waste water separated by the solid-liquid separators 4A and 4B is purified by the biological treatment apparatus 12 shown in FIG. By adopting such a configuration, in addition to the effects shown in the first and second embodiments, the following effects can be obtained. In the biological treatment apparatus 12 of the fourth embodiment, the sludge drainage in the sedimentation tank 15 is sent to the re-aeration tank 31 and the aerobic microorganisms in the sludge are starved and returned to the aeration tank 14. There is an effect that the organic matter in the tank 14 is adsorbed and decomposed to promote the purification of the mixed waste water.

Embodiment 5. FIG.
FIG. 6 is a flowchart regarding the biological treatment apparatus in the cocoon treatment system according to the fifth embodiment. The same or corresponding parts as those in FIG. The biological treatment apparatus 12 of the fifth embodiment is applied to the cocoon treatment system of the second embodiment. The biological treatment apparatus 12 of the fifth embodiment is different from the biological treatment apparatus 12 of FIG. 4 shown in the third embodiment in that the re-aeration tank 31 shown in the fourth embodiment is added. The sludge drainage in the lower layer is returned to the re-aeration tank 31, and the sludge drainage in which the aerobic microorganisms are starved in the re-aeration tank 31 is returned to the storage tank 13 by the return pipe 37. The point is very different.

  Next, the operation of the biological treatment apparatus 12 in the fifth embodiment will be described. The mixed waste water of kitchen waste water and separated liquid flows into the storage tank 13 from the kitchen drain pipe 1F, and the mixed waste water staying in the storage tank 13 and subjected to aerobic treatment is transferred into the aeration tank 14 by the transfer means 16. The mixed waste water aerobically treated in the aeration tank 14 flows into the settling tank 15, and the supernatant water overflows the overflow weir 29 in the settling tank 15 and is discharged out of the system from the supernatant water transfer pipe 30. This is the same as the biological treatment apparatus 12 in the third embodiment.

  In the biological treatment apparatus 12 in the fifth embodiment, the sludge drainage in the sedimentation tank 15 is returned to the re-aeration tank 31 in a fixed amount from the sludge return pipe 181 of the sludge return means 18. In the re-aeration tank 31, the aerobic microorganisms contained in the sludge are activated by the aeration device 32 and are in a starved state. After that, the sludge drainage in the re-aeration tank 31 is pushed out in the form of overflowing the return pipe 37 by the inflow of the sludge drainage returned later and flows into the storage tank 13. In the storage tank 13, the mixed waste water from the kitchen drain pipe 1F and the sludge waste water from the re-aeration tank 31 are mixed. Since the aerobic microorganisms are already activated in the re-aeration tank 31, the sludge in the storage tank 13 immediately adsorbs organic matter in the mixed waste water in the storage tank 13, and further diffuses the air diffuser 21. Microbubble air discharged from the trachea 22 is obtained, organic substances in the mixed waste water are decomposed, and aerobic treatment is performed.

  The mixed waste water subjected to the aerobic treatment in the storage tank 13 sequentially flows to the aeration tank 14 through the transfer pipe 161 by the operation of the transfer pump 160 of the transfer means 16. In the aeration tank 14, air is discharged from the air diffuser 26 of the air diffuser 25, and the aerobic microorganisms in the sludge decompose organic matter and continue the aerobic treatment. During this time, the mixed waste water aerobically treated in the aeration tank 14 flows over the transfer pipe 17 and flows to the settling tank 15, and the amount thereof is the same as the amount of the mixed waste water flowing into the aeration tank 14 from the storage tank 13. Become.

  In the sedimentation tank 15, the mixed waste water is allowed to stand and a precipitation treatment is performed to separate the upper supernatant water and the lower sludge waste water. The upper supernatant water overflows the overflow weir 29 and flows out of the system through the supernatant water transfer pipe 30. Also in this case, the amount of the supernatant water that overflows the overflow weir 29 is the amount of the sludge drainage that is returned from the sedimentation tank 15 to the re-aeration tank 31 from the amount of mixed drainage that flows from the aeration tank 14 into the sedimentation tank 15. It is the amount after subtracting the amount of water. The sludge drainage in the settling tank 15 flows into the re-aeration tank 31 through the return pipe 181 and the measuring tank 182 from the pump pot by the operation of the return pump 180 of the return means 18.

  In the re-aeration tank 31, air is discharged from the air diffusion pipe 33 of the air diffusion device 32 to aerate the sludge drainage that tends to be anaerobic. As a result, the aerobic microorganisms in the sludge are reactivated and recovered to a state where the organic matter can be adsorbed and decomposed, and the organic matter already adsorbed by itself and the organic matter in the waste water are adsorbed and decomposed. In addition, aerobic microorganisms self-grow when the organic matter is decomposed in the aeration tank 14 and the re-aeration tank 31, and thus the amount of sludge increases. However, the aerobic microorganism decomposes all the organic substances in the re-aeration tank 31. After that, the aerobic microorganisms start auto-oxidation (cannibalism) after that, so that the aerobic microorganisms in the sludge wastewater that has increased excessively decreases, and the amount of sludge becomes appropriate. And the sludge drainage in which aerobic microorganisms decreased flows through the return pipe 37 to the storage tank 13. The biological treatment apparatus 12 in the fifth embodiment performs the aerobic treatment of the mixed waste water by the above flow.

  As described above, in the dredging system according to the fifth embodiment, the mixed waste water of the separated liquid and the kitchen waste water separated by the solid-liquid separators 4A and 4B is purified by the biological treatment apparatus 12 shown in FIG. By adopting the configuration, in addition to the effects shown in the first to fourth embodiments, the following effects can be obtained. In the biological treatment apparatus 12 according to the fifth embodiment, since the aerobic treatment is performed in the three tanks of the storage tank 13, the aeration tank 14, and the re-aeration tank 31, the biological treatment apparatus shown in the conventional fourth embodiment. Even with the same installation area, the overall purification capacity can be greatly increased as compared with the prior art. Moreover, when processing with the same purification ability as before, it becomes possible to further promote the autooxidation of aerobic microorganisms in the sludge, and there is an effect that the discharge amount of the excess sludge can be greatly suppressed. Therefore, there is an effect that labor costs necessary for carrying out excess sludge and costs for treating it as industrial waste can be greatly reduced.

Embodiment 6 FIG.
FIG. 7 is a flowchart of the cocoon processing system according to the sixth embodiment. The same parts as those in FIG. The soot treatment system according to the sixth embodiment is greatly different from the second embodiment in that the dryers 6A and 6B are provided for drying the pulverized solid after the solid-liquid separation by the solid-liquid separators 4A and 4B. Different.

  The dryers 6A and 6B have a type in which the residual moisture of the pulverized solid is evaporated by an electric heater, a type in which the residual moisture is evaporated from the outside of the storage container for the pulverized solid by combustion heat from gas fuel, and the storage of the pulverized solid There is a type that forms a steam chamber that covers the outside of the container and causes high-temperature steam to flow through the steam chamber to evaporate the residual moisture of the pulverized solid, but the residual moisture can be reduced by drying the pulverized solid. Any configuration is possible if possible. However, if the pulverized solid is evaporated until it is carbonized, the energy derived from the organic matter in the pulverized solid is lost, so in the soot treatment system of this Embodiment 6, such a drier is used. Unsuitable. In addition, also in the cocoon processing system of this Embodiment 6, each processing flow shown in Embodiment 2 to Embodiment 5 is applicable as the biological treatment apparatus 12. In addition, in the case where the purification capacity of the sewage treatment plant responsible for the wastewater treatment of the building has a sufficient margin, the biological treatment device 12 is not particularly installed in the building, and after solid-liquid separation of the pulverized solid from the pulverized culm The mixed waste water of the separated liquid and kitchen waste water may be discharged to the sewer without being purified.

As described above, the bag processing system according to the sixth embodiment has the following effects in addition to the effects described in the first to fifth embodiments. In the soot treatment system according to the sixth embodiment, the dryers 6A and 6B for drying the crushed solids after the solid-liquid separation by the solid-liquid separators 4A and 4B in the second embodiment are provided. The pulverized solids can be dried by 6A and 6B to reduce the residual moisture in the pulverized solids, so that the amount of pulverized solids can be reduced and the work labor at the time of carrying out can be reduced. Further, as described above, the residual moisture in the pulverized solid is reduced, so that the activity of microorganisms such as bacteria can be suppressed, and the decay rate of the pulverized solid can be reduced. Therefore, even if the frequency of carrying out the pulverized solids is reduced (even if the storage days of the pulverized solids is increased), there is an effect that problems such as odor due to decay are less likely to occur. Furthermore, even when pulverized solids are fed into a fermenter as raw materials for fermentation treatment such as methane in a bioplant, the water-to-water ratio is greatly reduced by the drying treatment by the dryers 6A and 6B. Therefore, there is a great effect that the temperature drop in the fermenter can be suppressed with smaller fluctuations, and more efficient processing can be performed.

Embodiment 7 FIG.
FIG. 8 is a flowchart of the cocoon processing system according to the seventh embodiment. The same parts as those in FIG. The soot processing system according to the seventh embodiment is provided with solubilizing devices 7A and 7B for liquefying the pulverized solid material after the solid-liquid separation by the solid-liquid separators 4A and 4B. 2 is very different.

The solubilizers 7A and 7B include, for example, a method of liquefying the pulverized solid by oscillating the pulverized solid with an ultrasonic oscillator, bacteria that dissolve the cell wall of the pulverized solid in a storage container for the pulverized solid, A method of solubilizing by adding a drug is applicable. In addition, also in the cocoon processing system of this Embodiment 7, each processing flow shown in Embodiment 2 to Embodiment 5 is applicable as the biological treatment apparatus 12. In addition, in the case where the purification capacity of the sewage treatment plant responsible for the wastewater treatment of the building has a sufficient margin, the biological treatment device 12 is not particularly installed in the building, and after solid-liquid separation of the pulverized solid from the pulverized culm The mixed waste water of the separated liquid and kitchen waste water may be discharged to the sewer without being purified.

  As described above, the bag processing system according to the seventh embodiment has the following effects in addition to the effects described in the first to fifth embodiments. In the soot processing system according to the seventh embodiment, the crushed solids separated by the solid-liquid separators 4A and 4B can be liquefied by the solubilizers 7A and 7B. When used for biogas generation in a plant, the ground solids are already liquefied before being put into the bioplant, so that it is possible to suppress primary degradation of the biogas plant's primary processing capacity when pouring waste. There is a big effect. In addition, there is a great effect that the number of processing days until biogas generation can be shortened.

Embodiment 8 FIG.
FIG. 9 is a flowchart of the cocoon processing system according to the eighth embodiment. The same parts as those in FIG. In the soot treatment system according to the eighth embodiment, a solid-liquid separator such as a screen type that can be continuously processed as a solid-liquid separator 4A, 4B but has a relatively low dewatering efficiency, such as a screen type, is selected. The point which provided dehydrator 8A, 8B for performing the dehydration process which reduces a moisture content about the solid substance after solid-liquid separation by solid-liquid separator 4A, 4B differs greatly from the said Embodiment 2. .

  In the dehydrators 8A and 8B, the separated water generated when the pulverized solid is dehydrated is discharged to the kitchen drain pipes 1A and 1B through the separated water transfer pipes 9A and 9B. Therefore, the kitchen drainage from each commercial kitchen, the separation liquid from the screen type solid-liquid separators 4A and 4B, and the separation water from the dehydrators 8A and 8B flow into the kitchen drain pipes 1A and 1B, They are joined by a single kitchen drain pipe 1F and flow into the biological treatment apparatus 12. A centrifugal dehydrator, a screw press, a belt press, or the like can be applied to the dehydrators 8A and 8B.

  During the pulverization process in the pulverizers 2A and 2B, the mixed waste water and pulverized wastewater continuously flow into the solid-liquid separators 4A and 4B. In the case of the screen-type solid-liquid separator, the separation liquid is continuously supplied from the screen. Since the crushed solid matter remaining on the screen can be easily removed from the screen to the storage container etc. with a scraper or the like, it can be used in a single kitchen such as a large commercial kitchen. Even when the amount of generation is very large, continuous processing is possible. On the other hand, however, the screen-type solid-liquid separator has a demerit that the water removal rate in the pulverized solid is lower than that of other types of solid-liquid separators. In the soot treatment system according to the eighth embodiment, the mixed waste water from the pulverizers 2A and 2B is continuously solid-liquid separated by the solid-liquid separators 4A and 4B capable of continuous processing such as a screen type. Then, the crushed solid matter having a high water content remaining on the screen is put into the dehydrators 8A and 8B in an intermittent process (batch process) and dehydrated, and the separated water is separated into the kitchen drain pipe 1A and the separated water transfer pipes 9A and 9B. By transferring to 1B, a pulverized solid with a low water content can be obtained. In addition, also in the sputum processing system of this Embodiment 8, each processing flow shown in Embodiment 2 to Embodiment 5 is applicable as the biological treatment apparatus 12. In addition, in the case where the purification capacity of the sewage treatment plant responsible for the wastewater treatment of the building has a sufficient margin, the biological treatment device 12 is not particularly installed in the building, and after solid-liquid separation of the pulverized solid from the pulverized culm The separated waste water, the separated water, and the mixed waste water of the kitchen waste water may be discharged into the sewer without being purified.

  As described above, the wrinkle processing system according to the eighth embodiment has the following effects in addition to the effects described in the first to fifth embodiments. In the dredging treatment system according to the eighth embodiment, continuous processing such as a screen type is performed as a solid-liquid separator that separates the pulverized solids pulverized by the pulverizers 2A and 2B supplied from the water feeders 3A and 3B into solid and liquid. Since the possible solid-liquid separation 4A, 4B is applied, even when a large amount of soot is generated, the crushed solid matter from the pulverizers 2A, 2B can be continuously flowed into the solid-liquid separators 4A, 4B for processing. There is an effect that can be done. Moreover, since the pulverized solid separated by the solid-liquid separators 4A and 4B is further dehydrated by the dehydrators 8A and 8B, the moisture content of the pulverized solid can be greatly reduced, and its weight and volume. Can be further reduced, and it has a great effect on further reduction of transportation work by human power, cost reduction of the transport vehicle, and reduction of environmental load. In addition, even when pulverized solids are introduced into a fermenter as a raw material for fermentation treatment such as methane in a bio plant, the water content is greatly reduced by the dehydrators 8A and 8B. There is a great effect that it can be suppressed with smaller fluctuations and more efficient processing can be performed.

Embodiment 9 FIG.
FIG. 10 is a flowchart of the cocoon processing system according to the ninth embodiment. The same parts as those in FIG. The basket processing system in the ninth embodiment is greatly different from the second embodiment in that the oil / fat separators 10A and 10B are provided in the kitchen drain pipes 1A and 1B of each commercial kitchen. In the soot processing system according to the ninth embodiment, the oil separators 10A and 10B are provided on the downstream side of the connecting portions of the kitchen drain pipes 1A and 1B with the separation liquid transfer pipes 5A and 5B, and these oil separators 10A are provided. , 10B, the mixed waste water of the separation liquid from which the fats and oils have been separated and removed and the kitchen waste water are joined together by a single kitchen drain pipe 1 and flowed into the biological treatment apparatus 12. Examples of the oil separators 10A and 10B include a grease interceptor, a system that removes by adsorption with a fibrous, cloth, or solid adsorbent, a system that solidifies and removes oil and fat with a chemical, and the like. Although applicable, any configuration may be used as long as the oil and fat content in the mixed waste water can be removed.

  Note that the soot processing system including the oil separators 10A and 10B according to the ninth embodiment can be applied to each of the soot processing systems shown in the first and third to eighth embodiments. In addition, in the case where the purification capacity of the sewage treatment plant responsible for the wastewater treatment of the building has a sufficient margin, the biological treatment device 12 is not particularly installed in the building, and after solid-liquid separation of the pulverized solid from the pulverized culm The mixed waste water of the separated liquid and kitchen waste water may be discharged to the sewer without being purified.

  As described above, the bag processing system according to the ninth embodiment has the following effects in addition to the effects described in the first to fifth embodiments. In the cocoon processing system according to the ninth embodiment, in particular, when the kitchen wastewater from the commercial kitchen contains a large amount of fat and oil, or when the pulverizers 2A and 2B contain a large amount of fat and oil. In many cases, fats and oils can be removed from the mixed waste water of the kitchen waste water and the separated liquid by the fat separators 10A and 10B, and thus the temperature of the mixed waste water while flowing down the kitchen drain pipe 1 naturally. Decreases and oil deposits on the inner wall of the pipe, the mixed waste water containing a large amount of oil and fat flows into the biological treatment device 12, the purification treatment load increases, the storage tank 13 of the biological treatment device 12, etc. It is possible to prevent the oil and fat from adhering to the inner wall surface and the pipe. In addition, the number of cleanings of the kitchen drain pipe 1 and the number of cleanings of the storage tank of the biological treatment apparatus 12 can be greatly reduced, and labor costs for cleaning can be reduced.

Embodiment 10 FIG.
FIG. 11 is a flowchart of the cocoon processing system according to the tenth embodiment. The same parts as those in FIG. In the kitchen processing system according to the tenth embodiment, the mixed waste water pulverized by the pulverizers 2A and 2B of each commercial kitchen is directly flowed into the kitchen drain pipes 1A and 1B and joined to the kitchen drain pipe 1F. The point that the solid-liquid separation is performed by one solid-liquid separator 4 is greatly different from the soot treatment system of the second embodiment.

  In the soot treatment system according to the tenth embodiment, the grinders 2A and 2B in each commercial kitchen use the soot and water mixed waste water crushed by these grinders 2A and 2B through the soot transfer pipes 11A and 11B, respectively. It is made to flow into the kitchen drain pipes 1A and 1B of the system. And it is the kitchen drain pipe 1F where each kitchen drain pipe 1A, 1B joins, and also arrange | positions one solid-liquid separator 4 in the upstream of the biological treatment apparatus 12, and it carries out solid-liquid separation processing collectively. It has become. Therefore, in the soot processing system of the tenth embodiment, unlike the soot processing systems of the first to ninth embodiments, the pulverized soot flows into the kitchen drain pipes 1A, 1B, 1F. .

  FIG. 12 is a piping system diagram showing an example in which the bag processing system of the tenth embodiment is applied to an accommodation facility having a plurality of commercial kitchens in a building. FIG. 13 is a diagram for a conventional apartment house. The piping system diagram of a dredging processing system is shown. However, in FIGS. 12 and 13, only the drainage pipes directly related to the present invention are shown, and the ventilation pipes necessary for the actual drainage equipment are omitted. There are restrictions such as different owners of apartments in each dwelling unit. For example, in the case of water supply piping, when water is supplied from a water supply standpipe in a common area to each unit on the same floor, a water supply side branch pipe that supplies water to a certain unit Is not placed under the floor or ceiling of other dwelling units. In the case of water supply pipes, a water supply stand pipe is provided in a shaft room shared by two adjacent units on the same floor provided in a common section, and each of the two units is supplied with two supply side branch pipes. ing. On the other hand, with regard to drainage pipes, when drainage generated in each dwelling unit on the same floor is merged with a drainage stack, drainage side branch pipes that transport the wastewater generated in one dwelling unit to the drainage stack are placed under and under the floor of another dwelling unit. It is not placed behind the ceiling of the floor dwelling unit. There is a case where a drainage standpipe is provided in the shaft room of the common part and the wastewater for two units is merged. Usually, a drainage standpipe is set up with a shaft space in each unit, and the drainage in the unit Often, a piping system is used to join the drainage horizontal branch pipe.

  In the case of the dredging transport pipe in the dredging treatment system for a conventional apartment house shown in FIG. 13, the dwelling unit nearest to the sink sink 50M in which the crusher 2M and the water feeder 3M are installed is the same as other drainage pipes. A shaft space is provided in the inside, and a culvert conveying standpipe 102M is installed, and the mixed waste water of the culm and water crushed by the pulverizer 2M is passed from the culm transport tube 11M to the culm transport side branch pipe 101M to the coral transport standpipe 102M. It is designed to merge. Furthermore, each dredging conveyance standpipe 102M joins and is connected to the dredging conveyance horizontal main pipe 103M under the lowest floor (the first floor in the case of FIG. 13), conveys mixed wastewater to the biological treatment device 12M, and is purified and processed there. It is to be released outside.

  On the other hand, as shown in FIG. 12, in the case where there are a plurality of commercial kitchens in a building such as an accommodation facility, there is no restriction as in a housing complex, so a kitchen drainage stand pipe is provided for each commercial kitchen. The kitchen drain pipes are arranged so that the number of standing pipes is as small as possible without being inefficient. In the case of FIG. 12, commercial kitchens are disposed at two locations on the n-th floor, and a sink sink 50 and a faucet 51 (water faucet, hot water faucet, hot water mixed water) are disposed in each commercial kitchen. Kitchen drainage from the sink sink 50 of each commercial kitchen is joined to the kitchen drainage pipes (horizontal branch pipes) 1A and 1B by the appliance drainage pipe 110, respectively. It joins the kitchen drain pipe (stand pipe). Similarly, with regard to kitchen wastewater generated in the commercial kitchen on the third floor, the kitchen wastewater joins from the kitchen drainage pipe (horizontal branch pipe) 1C to the kitchen drainage pipe (stand pipe) 1F.

  In the example shown in FIG. 12, crushers 2A, 2B, 2C and water feeders 3A, 3B, 3C are provided at one drain outlet of a plurality of sink sinks 50 in each commercial kitchen. The mixed drainage of water and water is joined to the nearest kitchen drainage pipe (horizontal branch pipe) 1A, 1B, 1C by the kitchen transfer pipes 11A, 11B, 11C, and joined to the kitchen drainage pipe (stand pipe) 1F, B1 floor The solid-liquid separator 4 separates the pulverized solids in the mixed wastewater of culm, water and kitchen wastewater, purifies the separated liquid with the biological treatment device 12, and discharges it to the sewer etc. outside the building. It has become.

  Note that each treatment flow shown in the second to fifth embodiments can be applied as the biological treatment apparatus 12 also in the cocoon treatment system of the tenth embodiment. In addition, when there is sufficient margin in the purification capacity of the sewage treatment plant responsible for the wastewater treatment of the building, the biological treatment device 12 is not particularly installed in the building, and the mixed wastewater of pulverized wastewater, water and kitchen wastewater is used. The mixed waste water after solid-liquid separation of the pulverized solid may be discharged into the sewer without purification.

As described above, in the soot processing system according to the tenth embodiment, in addition to the effects shown in (1) to (6) in the first embodiment and the effects shown in the second to fifth embodiments. There are the following effects.
(1) As shown in FIG. 13, in the case of the soot processing system for apartment houses, the soot conveying standpipe 102M is provided on the same floor near the crusher 2M of each dwelling unit. For this reason, the mixed drainage of pulverized culm and water can be joined to the culm transport standpipe 102M through a short horizontal transport path, and the amount of pulverized culm generated from one dwelling unit is small. There is almost no risk of pulverized solids remaining in the tube. On the other hand, as shown in FIG. 12, when a grinder is transported by a pipe dedicated for firewood transportation in a building having a plurality of commercial kitchens, a large amount of grinders are generated from one commercial kitchen. Unlike the case of constrained apartments, the number of kitchen transport standpipe can be reduced as much as possible (see kitchen drainpipe 1F), so the horizontal distance from the crusher 2B to the kitchen transport standpipe is long (kitchen drainpipe) 1B), in the case of a mixed waste water amount of only pulverized slag and water for washing the pulverizer, pulverized solids are likely to stay during the horizontal transfer (only the slag transfer pipe 11B is connected to the kitchen drain pipe 1B. Because of the situation, the flow rate of the mixed waste water flowing down the pipe is small.) In a normal building, the floor layout in the floor may differ greatly between the upper and lower floors (for example, the second floor and the first floor) (for example, in the case of an accommodation facility, the top floor is the observation restaurant. In many cases, the plane position of the pipe shaft, which is the accommodation room for the middle class and the banquet room for the lower class, and the storage space for the standing pipes, changes greatly between the upper and lower floors. In this case, under the upper floor, it is necessary to use a so-called unfolded pipe that is extended horizontally to the pipe shaft of the lower floor (see the horizontal kitchen drain pipe 1F below the second floor). In the same way, the vertical pipe in the pipe shaft on the upper floor is changed to a horizontally expanded pipe, and the vertical pipe is changed again on the pipe shaft on the lower floor. This expanded piping section also has a long horizontal distance, and the pulverized solid matter tends to stay during the conveyance of the pulverized slag in the horizontal direction. On the other hand, in the case of the soot treatment system according to the tenth embodiment, the waste water mixed with the soot and water crushed by the pulverizers 2A, 2B, and 2C is joined to the kitchen drain pipes (lateral branch pipes) 1A, 1B, and 1C. Because the kitchen drainage pipe has a large amount of water flowing in the kitchen drain pipe, the pulverized solid can be easily transported even when the horizontal transport distance is long. There is no risk of things staying at the bottom of the pipe. Further, since the pulverized solid material is transported together with the kitchen drainage from the plurality of kitchens in the development piping section, there is no possibility of staying at the bottom of the piping.
(2) When there is a single business operator that has a commercial kitchen in the building, such as an accommodation facility, or the single business operator has another commercial kitchen as a tenant. In the case of a business form in which a business operator performing a store is opened, it is easy to use the basket processing system in all commercial kitchens in the building. Further, in this case, the kitchen drain pipes 1A and 1B can easily take a form in which one large solid-liquid separator 4 is installed in the kitchen drain pipe 1F and maintained by a worker of the building facility. Both initial cost and running cost can be significantly reduced as compared with the soot processing system described in the ninth aspect.

Embodiment 11 FIG.

The soot treatment system according to the eleventh embodiment is the same as that of the tenth embodiment in the drying machine similar to that shown in the sixth embodiment for drying the pulverized solid after the solid-liquid separation by the solid-liquid separator 4. 6 is greatly different.

  As described above, in the soot processing system according to the eleventh embodiment, in addition to the effects shown in the tenth embodiment, the effects shown in the sixth embodiment can be obtained at the same time. Further, since the pulverized solid is dried at one place, the processing efficiency is improved as compared with the case where the pulverized solid is individually dried as in the sixth embodiment, and electricity, gas, steam The amount of use can be significantly reduced.

Embodiment 12 FIG.
FIG. 15 is a flowchart of the cocoon processing system according to the twelfth embodiment. The same parts as those in FIGS. The soot treatment system in this twelfth embodiment is the same as that of the tenth embodiment in the same manner as that shown in the seventh embodiment in which the pulverized solid material after solid-liquid separation by the solid-liquid separator 4 is liquefied. The point which provided the solubilizer 7 differs greatly.

  As described above, the wrinkle treatment system according to the twelfth embodiment has the effect of simultaneously obtaining the effects shown in the seventh embodiment in addition to the effects shown in the tenth embodiment. Further, since the pulverized solid is solubilized at one place, the processing efficiency is improved as compared with the case where the pulverized solid is solubilized individually as in the seventh embodiment. The amount used can be greatly reduced.

Embodiment 13 FIG.
FIG. 16 is a flowchart of the cocoon processing system according to the thirteenth embodiment. The same parts as those in FIGS. The soot treatment system according to the thirteenth embodiment is different from the tenth embodiment in the screen-type solid-liquid separation that is easy to perform the continuous processing shown in the eighth embodiment as the solid-liquid separator 4 but has a relatively low dehydration efficiency. The point which provided the dehydrator 8 for performing the dehydration process which lowers | hangs the moisture content about the pulverized solid substance after selecting the machine and solid-liquid-separating with the solid-liquid separator 4 differs greatly. The separated water generated when the pulverized solid is dehydrated by the dehydrator 8 is transferred to the kitchen drain pipe 1F downstream of the solid-liquid separator 4 and upstream of the biological treatment apparatus 12 by the separated water transfer pipe 9. It is supposed to be discharged.

  As described above, in the wrinkle processing system according to the thirteenth embodiment, in addition to the effects shown in the tenth embodiment, the effects shown in the eighth embodiment can be obtained at the same time. Further, since the dehydrated processing of the pulverized solid is performed at one place, the processing efficiency is improved as compared with the case where the dehydrated processing of the pulverized solid is individually performed as in the eighth embodiment, and the usage amount of electricity, etc. There is an effect that can be greatly reduced.
