Description

The present invention is, for example, a drainage process for treating drainage discharged from kitchens of various facilities such as lunch centers, restaurants, hotels, food processing shops, supermarkets, department stores, hospitals, and other kitchens (discharge sources). The present invention relates to a method and a drainage treatment apparatus .

  Kitchens such as lunch centers, hotels, food processing shops, supermarkets, department stores, hospitals, restaurants, etc. include cooking oil, food waste, food left over, chopsticks, toothpicks, paper scraps, plastic scraps, other garbage, etc. A liquid etc. (hereinafter referred to as “drainage”) accompanying the occurrence of the liquid is routinely generated. In Japan, it is prohibited to drain wastewater that does not conform to the “Emission Standards for Water Pollution Control Law” directly into the sewer pipe and drain pipe, so the liquid storage currently installed in the kitchen (or outside the kitchen) The actual situation is that drainage is stored in a tank (grease wrap) and the effluent in the grease wrap is periodically cleaned by a cleaning company, for example, once a week or once a month. It is.

  However, since the wastewater is not sufficiently purified by cleaning by the cleaning company, in addition to cleaning, the wastewater is neutralized with a neutralizing agent to meet the discharge allowable limit (discharge standard value), and then the sewer is removed from the grease trap. And discharged into the septic tank. Accordingly, secondary costs and labor are required and the cost is increased accordingly. In addition, the grease trap fills up until the next regular cleaning day, and the drainage may flow untreated into the drainage and sewage pipes, causing environmental pollution and odors in the kitchen. It was the cause.

  In small restaurants and convenience stores, there may be cases where sufficient space for installing the grease strap cannot be secured, and only a small (small) grease strap may be installed. In this case, the frequency of the cleaning or neutralization treatment increases, and each time, labor and cost are required. For this reason, there is a demand for development of a drainage treatment means that does not require frequent drainage treatment even if it is small.

  The inventor of the present application has previously developed a grease trap drainage treatment apparatus for treating the grease trap drainage disclosed in Patent Document 1. While pumping up the drainage liquid from the grease wrap, supplying the soap solution to the drainage liquid, mixing and stirring to make the soap solution (saponification), and returning the soap solution (saponification solution) into the grease strap ( (Or to the outside).

  According to the grease trap drainage processing apparatus of Patent Document 1, since the drained liquid sucked from the grease strap is saponified and returned to the grease trap, there is no problem of environmental pollution due to oils and fats and detergents. There is an advantage that it is cleaned.

[Embodiment of drainage treatment method]
An example of an embodiment of the drainage treatment method of the present invention will be described with reference to FIG. The drainage treatment method of the present invention is a “place where drainage is generated” (hereinafter referred to as “a place where drainage occurs”) such as kitchens of various facilities such as lunch centers, restaurants, hotels, food processing plants, supermarkets, department stores, and hospitals. This is a method for treating the drainage from the discharge source. In the conventional method, the drainage treatment is performed after the drainage is once accumulated in the grease trap. In this case, the drainage treatment is performed directly to meet the discharge allowable limit (discharge standard value) before (or without) collecting.

  FIG. 1 is an overall view showing a state in which the drainage treatment apparatus 1 of the present invention is arranged. A drain pipe T is connected to a sink R installed at a discharge source, and the drain pipe T is connected to the drain pipe T of the present invention. The liquid processing apparatus 1 is connected, and a grease trap A is installed at the tip of the drainage processing apparatus 1. As can be seen from this figure, the drainage B from the discharge source, that is, the drainage B flowing out from the sink R is sucked into the agitation processing device 2, and at the same time, the processing agent stored in the processing agent container 3 is also stirred. Inhaled. In this way, the waste liquid B and the treatment agent are sucked together, whereby the waste liquid B and the treatment agent are agitated in the agitation processing apparatus 2, and as a result, a mixed liquid of the agitated waste liquid B and the treatment agent. (Hereinafter, referred to as “stir-treated drainage B” for convenience) is discharged to the grease strap A. Of course, it is also possible to discharge to the outside such as a sewer pipe without discharging to the grease wrap A.

  A typical agent used as a treating agent is a saponifying agent (saponifying solution), and this saponifying agent is used to make the oil and fat of the drainage B in particular a soap liquid (to make a soaping solution). Liquid, gel, powder, and other saponifying agents can be used. As an example of the saponifying agent, the applicant's product (trade name “Clean Ecoflow”) can be used, and the main components contained in the “Clean Ecoflow” are fatty acid sodium, fatty acid potassium, palm fatty acid jetanol. Amides, some inorganics, purified water, etc. The treating agent is not limited to a saponifying agent as long as the drainage B can be modified to be environmentally friendly, and a surfactant, a deodorant, a neutralizing agent, or a mixture of two or more of these may be used. it can.

  The drainage treatment apparatus 1 shown in FIG. 1 is an example, and the drainage treatment apparatus 1 can employ various forms described later. In short, before discharging the drainage B from the discharge source to the grease wrap (or the outside such as a sewer pipe), a treatment agent is added to the drainage B, and the drainage B and the treatment agent are agitated and stirred. If the discharged liquid B can be discharged, various means can be adopted as the discharged liquid processing method of the present invention.

[First Embodiment of Drainage Treatment Apparatus]
A first embodiment of the drainage treatment apparatus of the present invention will be described with reference to FIG. FIG. 1 is an overall perspective view showing a state in which the drainage treatment apparatus 1 according to the first embodiment is arranged. The drainage treatment apparatus 1 according to the present embodiment includes a stirring treatment device 2 and a treatment agent container 3, and directly stirs the drainage B from the discharge source (before discharging it to the grease trap).

(Treatment agent container and treatment agent)
The processing agent container 3 includes a container main body 3a and an inflow path 3b using a tube, a tube, and the like. The container main body 3a stores the processing agent, and the inflow path 3b is a processing agent in the container main body 3a. Is a passage for moving to the stirring processing device 2. A typical agent used as a treatment agent is a saponifying agent, and this saponifying agent is particularly used to make the oil and fat content of the drained liquid B into a soap liquid (soap liquid). Powdered or other saponifying agents can be used. As an example of the saponifying agent, the applicant's product (trade name “Clean Ecoflow”) can be used, and the main components contained in the “Clean Ecoflow” are fatty acid sodium, fatty acid potassium, palm fatty acid jetanol. Amides, some inorganics, purified water, etc. The treating agent is not limited to a saponifying agent as long as the drainage B can be modified to be environmentally friendly, and a surfactant, a deodorant, a neutralizing agent, or a mixture of two or more of these may be used. it can.

  The ratio of the saponifying agent supplied to the effluent B is preferably about 5: 1 from the effluent B: saponifying agent considering the soaping efficiency and cost, but this ratio should be changed depending on the degree of contamination of the effluent B. For example, the ratio of the saponifying agent can be increased when the dirt is remarkable, and the ratio of the saponifying agent can be decreased when the dirt is small.

  The container main body 3a of the processing agent container 3 is provided with an inlet (not shown) through which a processing agent can be introduced, and the processing agent introduced from the inlet is accommodated in the container main body 3a. The processing agent is supplied to the agitation processing apparatus 2 through the inflow path 3b.

(Agitation processing equipment)
The agitation processing apparatus 2 is provided with suction means, and the suction means sucks the drained liquid B from the discharge source (here, the sink R) into the agitation processing apparatus 2. The suction means includes a built-in pressure device (not shown) such as a vacuum pump and an inflow port 2a. As shown in FIG. 1, the inflow pipe S connected to the drain pipe T of the sink R joins the inflow path 3b in the middle. For this reason, when the drainage B is sucked into the stirring processing device 2 by the suction means, the processing agent in the container body 3 a is also sucked into the stirring processing device 2 at the same time. In FIG. 1, a joint U (T-shaped tube) is used as a joining means between the inflow pipe S and the inlet / outlet path 3b. However, various means conventionally used (for example, the inflow pipe) are used for this joining means. It is also possible to adopt a means for directly penetrating the delivery path 3b into S.

  The drainage B and the treatment agent sucked into the stirring treatment device 2 by the suction means are mixed in the stirring treatment device 2 and stirred by the suction force of the pressure device. The drainage liquid B to which a treatment agent such as a saponifying agent is added is converted into a soap liquefaction. By stirring in this way, the liquefaction of the drainage liquid B is remarkably promoted.

  The waste liquid B added with the treatment agent and stirred (hereinafter, a series of these treatments is referred to as “stirring treatment”) is discharged by a discharge means provided in the stirring treatment device 2. This discharge means is composed of a built-in pressure device such as a vacuum pump (not shown) and a discharge port 2b, and the drainage B stirred by this pressure device is pumped from the discharge port 2b. Note that the pressure device of the discharge means can be omitted, and in this case, for example, the drained liquid B that has been stirred can be freely dropped from the discharge port 2b. Further, the pressure device of the discharge means can also be used as the pressure device of the suction means.

  The drainage B can be discharged to the grease strap A through the external discharge pipe 4 connected to the discharge port 2b, or can be discharged to the outside such as a sewer pipe. On the other hand, in Japan, according to the provisions of the Sewerage Law (Article 12), it is obliged to discharge the effluent discharged from commercial kitchens after being treated with a septic tank interceptor (such as grease trap). In addition, the structure of this interceptor conforms to the standard related to the interceptor among SHASE-S established by the Air Conditioning and Sanitary Engineering Association, or the sewer business manager is equivalent to the standard of SHASE-S. It must be recognized as the above performance. Therefore, the drainage treatment apparatus 1 of the present invention is made to have a performance equivalent to or better than the grease strap, that is, a performance that conforms to the standard related to the interceptor of SHASE-S, or a performance equivalent to or better than this standard. For example, it can be discharged to the outside such as a sewer pipe without providing the grease strap A. This also applies to Embodiments 2 to 3 described later.

  The agitation processing apparatus 2 that can be used here only needs to include the above-described suction means and discharge means, and may be newly created as a dedicated product of the drainage processing apparatus 1 of the present invention, or a commercially available vane pump. (For example, a rubber vane pump manufactured by Ebara Corporation) may be used.

[Second Embodiment of Drainage Treatment Apparatus]
A second embodiment of the drainage treatment apparatus of the present invention will be described with reference to FIG. The drainage treatment apparatus 1 of this embodiment is provided with a storage tank 5 in addition to the agitation processing apparatus 2 and the treatment agent container 3, and the structure and operation of those except the storage tank 5 are the same as those of the first embodiment. The contents not described in the present embodiment are the same as those in the first embodiment.

  FIG. 2 is an overall view showing a state in which the drainage treatment apparatus 1 according to the second embodiment is arranged. In this embodiment, the drainage B from the discharge source (here, the sink R) flows directly into the storage tank 5 to be stored, and flows into the agitation processing device 2 through the inflow pipe S, and the agitation processing device 2 and the processing agent. The container 3 is stirred. Further, the drainage B subjected to the agitation process is discharged to the grease lap A (or outside the sewer pipe without passing through the grease lap A) by the discharging means of the agitation treatment device 2. The structures and operations of the stirring treatment device 2 and the processing agent container 3 in the present embodiment are the same as those in the first embodiment. However, while the waste liquid B sucked by the suction means of the agitation processing apparatus 2 in the present embodiment is in the storage tank 5, the drain liquid B sucked by the suction means in the first embodiment is a source of discharge (a sink). R) is different.

(Reservoir)
The storage tank 5 shown in FIG. 2 includes a tank body 5a that stores the drainage B, a support leg 5b that supports the tank body 5a, and a discharge port 5c that discharges the drainage B in the tank body 5a. In addition, an inflow pipe S is connected to the discharge port 5c through an on-off valve 6. The storage tank 5 is disposed immediately below the sink R and directly receives the drainage B flowing down from the sink R. Therefore, the tank body 5a is partially opened (or entirely) in the upper part. The tank body 5a has a space in which the drainage B can be stored. FIG. 2 shows a rectangular parallelepiped shape, but if the drainage B can be stored, The shape is not limited to an arbitrary shape such as an oval shape or a polygonal shape in plan view.

  In order to measure the amount of the drainage B stored in the storage tank 5, a drainage amount measuring means such as a float 7 can be provided. If the opening / closing operation of the on-off valve 6 is performed based on the measurement result (drainage amount), the drainage treatment work becomes efficient. Furthermore, it is preferable to install a control means (not shown) and automate the opening / closing operation of the on-off valve 6 based on the measurement result, because the drainage processing work becomes more efficient.

  The storage tank 5 is not limited to that shown in FIG. 2, but may be divided into two tanks as shown in FIG. FIG. 3 is an overall view when the storage tank 5 of the drainage treatment apparatus 1 in the second embodiment is two tanks. The storage tank 5 shown in this figure overflows from the first storage tank 51 and the first storage tank 51 storing the drainage B flowing down directly from the sink R by providing the partition wall 53 in the tank body 5a. It is divided into a second storage tank 52 for storing the drainage B. The partition wall 53 is lower than the side wall constituting the tank body 5a of the storage tank 5. When the storage capacity of the first storage tank 51 is exceeded, the drainage B overflows (overflows) over the partition wall 53. ) It flows into the second storage tank 52 and is stored in the second storage tank 52. Of the moisture and fats and oils in the drainage B, the fats and oils float on the liquid surface due to the difference in specific gravity, so the oil and fat in the drainage B mainly flows from the first storage tank 51 to the second storage tank 52. It is. That is, since most of the fat and oil to be processed in the drainage B is stored in the second storage tank 52, the drainage treatment of the drainage B in the second storage tank 52 is efficient. In addition, in order to make the waste liquid B in the 2nd storage tank 52 flow in into the stirring processing apparatus 2, as shown in FIG. 3, the inflow pipe S is inserted from the upper direction of the 2nd storage tank 52, and the stirring processing apparatus 2 The drainage B in the second storage tank 52 may be sucked by the suction means, and the agitation processing device through the on-off valve 6 and the inflow pipe S from the discharge port 5c provided in the second storage tank 52 as in FIG. 2 may be allowed to flow. As shown in the figure, the first storage tank 51 and the second storage tank 52 are provided with a discharge port (drain) and an on-off valve 6 for discharging the drainage B therein (for example, during maintenance). You can also.

  Also in this case, in order to measure the amount of the drainage B stored in the second storage tank 52, a drainage amount measuring means such as the float 7 can be provided, or a control means is installed and based on the measurement result. The suction operation (by the suction means of the stirring processing device 2) can be automated.

  The storage tank 5 can be supported by the support legs 5b shown in FIG. 2, but as shown in FIG. 3, the storage tank 5 can also be a mobile type in which casters J are installed at the bottom. In this case, the storage tank 5 can be easily moved, which is preferable. Of course, the caster J can be rotatable or can be provided with a stopper.

  The storage tank 5 can also be disposed adjacent to the sink R as shown in FIG. FIG. 4 is an overall view when the storage tank 5 of the drainage treatment apparatus 1 according to the second embodiment is disposed adjacent to the side of the sink R. As shown in this figure, a pump P is provided in the discharge pipe W connected to the drain pipe T of the sink R in order to allow the drainage B from the sink R to flow into the first storage tank 51. Due to the lift of the pump P, the drainage B from the sink R is pumped up to above the first storage tank 51 and flows down into the first storage tank 51. In FIG. 4, the storage tank 5 is divided into two tanks as in FIG. 3, but it may be one tank as shown in FIG. In addition, the installation of the float 7 (including automatic operation) and the selection of the support method (support leg 5b or caster J) of the storage tank 5 are the same as those described with reference to FIGS.

  As described above, when the treatment agent is supplied to the waste liquid B and stirred, the oil and fat content in the waste liquid B becomes a soap liquid, but the action of liquefying the oil and fat is generally the temperature of the waste liquid B. Affected. It is known that when the temperature of the drainage B is extremely low, such as in a cold region, it is difficult to liquefy soap with oil. Therefore, it is preferable to install the heating means 8 that raises the temperature of the drainage B stored in the storage tank 5 to an appropriate temperature because the liquefaction of oil and fat is promoted. In FIG. 4, a heater is installed on the side surface of the storage tank 2 as the heating means 8, but a conventionally used heating technique can be used, and the installation position can be designed as appropriate. In addition, it is possible to install a temperature sensor and operate the heating means 8 only when the temperature of the drainage B is outside the predetermined temperature range. This heating means 8 is not limited to the case of FIG. 4, but can be naturally installed in FIGS.

[Third embodiment of the drainage treatment apparatus]

At this time, as shown in FIG. 5, if necessary, a pump P can be arranged in the discharge pipe W, and the drainage B can be pumped up to an opening provided in the upper part of the storage tank 10. The treatment liquid is supplied from the treatment agent device 9 to the waste liquid B that is directly charged into the storage tank 10 and stored, and the mixed liquid of the waste liquid B and the treatment agent is stirred by the stirring device 11 to be drained. Is done. The drainage B thus drained is discharged from the outlet 12.

(Processing agent equipment)
The treatment agent device 9 includes a treatment agent container 9a capable of containing the treatment agent and a treatment agent supply means for supplying the treatment agent into the storage tank 10, and the treatment agent supply means is provided with the treatment agent container 9a. And a discharge pipe 9b that communicates with the storage tank 10 and a pressure feeding means for feeding the treatment agent from the treatment agent container 9a to the discharge pipe 9b. A typical example of the treating agent used is a saponifying agent, and this saponifying agent is used to make the fat and oil in the drained liquid B into a soap liquid (soaping liquid). , Powders and other saponifying agents can be used. As an example of the saponifying agent, the applicant's product (trade name “Clean Ecoflow”) can be used, and the main components contained in the “Clean Ecoflow” are fatty acid sodium, fatty acid potassium, palm fatty acid jetanol. Amides, some inorganics, purified water, etc. The treating agent is not limited to a saponifying agent as long as the drainage B can be modified to be environmentally friendly, and a surfactant, a deodorant, a neutralizing agent, or a mixture of two or more of these may be used. it can.

  The ratio of the saponifying agent supplied to the effluent B is preferably about 5: 1 from the effluent B: saponifying agent considering the soaping efficiency and cost, but this ratio should be changed depending on the degree of contamination of the effluent B. For example, the ratio of the saponifying agent can be increased when the dirt is remarkable, and the ratio of the saponifying agent can be decreased when the dirt is small.

  The processing agent container 9a is provided with an input port (not shown) through which the processing agent can be input, and the processing agent input from this input port is accommodated in the processing agent container 9a. The processing agent in the processing agent container 9a is supplied into the storage tank 10 by the processing agent supply means. Among the processing agent supply means, various techniques conventionally used can be employed as the pressure feeding means. For example, the motor M shown in FIG. 5 can be used as a driving source to pressurize the processing agent in the processing agent container 9a, or a pump can be installed in the discharge pipe 9b to suck the processing agent. You can also Further, the processing agent container 9a is installed at a position higher than the storage tank 10, and an opening / closing valve is provided in the discharge pipe 9b, and the processing agent is dropped into the storage tank 10 by the operation of the opening / closing valve. Can be omitted.

  As shown in FIG. 5, when two storage tanks 10 are provided, the processing agent is supplied into the second storage tank 10b that receives the overflowed drainage B, and only the drainage B in the second storage tank 10b is processed. Alternatively, all the drainage B can be processed by supplying a treatment agent to both the first storage tank 10a and the second storage tank 10b.

(Reservoir tank for agitation processing equipment)
The storage tank 10 includes a space in which the drainage B can be stored, and can receive the drainage B directly from an opening provided above the storage tank 10. The storage tank 10 in FIG. 5 is a rectangular parallelepiped, and has a structure in which four of the six surfaces and the bottom surface are closed and only the top surface is opened, but the drainage B can be directly received. As long as the drainage B can be stored in the inside, the shape is not limited to this, and any shape such as an oval shape or a polygonal shape can be used in a plan view. The upper surface portion can be configured to block other portions (other than the opening portion) as long as it can secure the opening that can allow the drainage B to flow in and can supply the treatment agent from the treatment agent device 9.

  The storage tank 10 shown in FIG. 5 is divided into two tanks, a first storage tank 10a and a second storage tank 10b, by a partition wall 10c provided inside. As shown in this figure, the first storage tank 10a stores the drainage B flowing directly from the sink R, and the second storage tank 10b discharges the drainage B overflowing from the first storage tank 10a. Is to be stored. The partition wall 10c is lower than the side wall constituting the storage tank 10, and when the storage capacity of the first storage tank 10a is exceeded, the drainage B overflows (overflows) over the partition wall 10c. It flows into 10b and is stored in the 2nd storage tank 10b. Of the moisture and fats and oils in the drainage B, the fats and oils rise from the specific gravity, and the oil and fat in the drainage B mainly flows from the first storage tank 10a to the second storage tank 10b. Minutes. That is, since most of the fat and oil to be processed in the drainage B is stored in the second storage tank 10b, it is efficient to drain the drainage B in the second storage tank 10b. Therefore, the processing agent may be supplied to the drainage liquid B in the second storage tank 10b, and the drainage B and the processing agent in the second storage tank 10b may be stirred. Of course, it is also possible to stir all the drainage B in the storage tank 10 as a single tank without partitioning the storage tank 10, and the storage tank corresponding to the most downstream (overflowing end) divided into three or more layers. It can also be set as the structure which stir-processes focusing on the drainage B of this.

(Agitator of agitation equipment)
The drainage liquid B to which a treatment agent such as a saponifying agent is added is liquefied with soap, but further stirring further promotes the liquefaction of the drainage B with soap. Therefore, the storage tank 10 of the drainage treatment apparatus 1 of the present embodiment is provided with a stirring device 11 that stirs the drainage B supplied with the treatment agent. The stirring device 11 can have an arbitrary structure such as a screw method or a vane method as long as the treatment agent and the drainage B can be effectively stirred. As an example, as shown in FIG. 5, a screw type stirring device 11 having a rotating shaft and blades can be provided. By rotating the rotating shaft, the blades stir the treating agent and the drainage B, and the liquefaction of the drainage B is significantly promoted. The rotation shaft rotates with the motor M shown in FIG. 5 as a drive source, and the rotation speed and rotation time (that is, the stirring time) can be arbitrarily designed depending on the degree of contamination of the drainage B. The motor M that rotates the rotating shaft can be used also as the motor M that is used when pressure-feeding the processing agent in the processing agent container 9a of the processing agent device 9, or a separate motor M is prepared for each. You can also In addition, when the storage tank 10 is made into 2 tanks as shown in FIG. 5, the stirring apparatus 11 is installed in the 2nd storage tank 10b which receives the overflowed waste liquid B, and only the drainage B in the 2nd storage tank 10b. Can be stirred, or all the drainage B can be stirred by installing the stirring device 11 in both the first storage tank 10a and the second storage tank 10b.

(Discharge means of the stirring treatment device)
The drainage B (the drainage B subjected to the drainage treatment) that has been supplied and stirred in the storage tank 10 is discharged out of the storage tank 10 by the discharge means. The discharge means includes a discharge port 12 provided on the bottom surface of the storage tank 10 and a pressure feeding means for pressure-feeding the drainage B to the outside. Conventionally used submersible pumps can also be adopted as the pumping means constituting the discharging means, but this pumping means is omitted as a structure for allowing the drainage B in the storage tank 10 to fall freely from the discharge port 12. You can also.

  As shown in FIG. 5, when two storage tanks 10 are provided, a discharge port 12 is provided on the bottom surface of the second storage tank 10b that receives the overflowed drainage B, and only the drainage B in the second storage tank 10b is provided. Can be discharged. Or all the drainage B can also be discharged by providing the discharge port 12 in the bottom face part of both the 1st storage tank 10a and the 2nd storage tank 10b. The drainage B can be discharged to the grease strap A through the external discharge pipe 4 connected to the discharge port 12, or can be discharged to the outside such as a sewer pipe. If the drainage treatment device 1 has a performance equivalent to or better than the grease strap, that is, a performance conforming to the standard related to the interceptor of SHASE-S, or a performance equivalent to or better than this standard, the grease strap A is used. It is the same as that of Embodiment 1 in that it can be discharged outside such as a sewer pipe without being provided.

(Drainage measurement means)
The draining process of supplying and stirring the treatment agent to the drainage B can be started at an arbitrary timing, but it is more efficient to carry out when the drainage B has accumulated to some extent in the storage tank 10. . For example, the drainage process can be started when a person monitors the inside of the storage tank 10 and confirms that the drainage B has reached a predetermined amount. In this case, the amount (reserved amount) of the drainage B stored in the storage tank 10 can be confirmed by visual observation. However, if a drainage amount measuring means 13 (FIG. 5) such as a water level gauge or a float is installed, it is more accurate. In addition, the storage amount of the drainage B can be confirmed.

  The effect of installing the drainage amount measuring means 13 is not limited to the case where the drainage processing operation is performed based on human judgment, and the drainage processing operation can be automatically performed. For example, a water level sensor is installed as the drainage amount measuring means 13, and the water level data acquired by the water level sensor is transmitted to an electronic computer (hereinafter referred to as "PC"), and the water level determined in advance by the personal computer. It is determined whether or not the drainage operation is performed in comparison with the threshold value. When the personal computer determines that the drainage processing operation is to be performed, a signal to that effect is sent to a control device (not shown), and the processing device 9 and the stirring device 11 are automatically operated by this control device. After that, when the drainage process elapses for a predetermined time, the drainage B is discharged from the discharge port 12 to the outside of the storage tank 10, the water level of the drainage B is also below the threshold, and this water level data is transmitted from the water level sensor to the personal computer. The personal computer instructs the control device to stop the operation of the treatment agent device 9 and the stirring device 11. Of course, the operation of the treatment agent device 9 and the stirring device 11 can be automatically stopped when the drainage process has passed for a predetermined time.

  Alternatively, a water quality measuring device (not shown) is provided to measure the water quality of the drainage B, and if the water quality satisfies a predetermined reference value, the operation of the treatment agent device 9 and the stirring device 11 is automatically stopped. You can also In this case, the water quality measurement, the display means for the measurement results, the determination of whether or not the reference value is satisfied, and the like may be the same as those described in “Embodiments 1 to 5 of grease trap drainage treatment apparatus” described later. it can. When measuring water quality, there are various measurement items. For example, in the “Water Pollution Control Act (Ministerial Ordinance for Establishing Wastewater Standards)”, the wastewater discharge standards are divided into pollution status due to harmful substances and pollution status due to non-toxic substances. Further, in the state of contamination by harmful substances, 27 measurement items such as the contents of cadmium and its compounds, cyanide compounds and hexavalent chromium compounds are listed, and in the state of contamination by substances other than harmful substances, 15 items are listed. Table 1 shows the measurement items and their reference values for measuring the pollution status of substances other than hazardous substances, as stipulated in the “Water Pollution Control Act (Ministerial Ordinance for Establishing Wastewater Standards)”.

  As the drainage amount measuring means 13, a contact type sensor can be used. Installed so that the detection part of the contact sensor is at a predetermined height, and when the liquid level of the drainage B rises and contacts the detection part of the contact sensor, the signal is transmitted to the control device and automatic operation is started ( (Or stop). Alternatively, a float can be installed as the drainage amount measuring means 13. In this case, the operation of the treatment agent device 9 and the agitation device 11 can be controlled by mechanically turning the switch on / off by the up and down of the float accompanying the up and down of the liquid level of the drainage B. In addition, a conventionally used technique can be used as the drainage amount measuring means 13.

(Heating means)
As described above, when the treatment agent is supplied to the waste liquid B and stirred, the fats and oils in the waste liquid B become a soap liquid, as described above. Affected by. It is known that when the temperature of the drainage B is extremely low, such as in a cold region, it is difficult to liquefy soaps and oils. Therefore, it is preferable to install the heating means 8 that raises the temperature of the drainage B stored in the storage tank 10 to an appropriate temperature because the soap liquefaction of oil and fat is promoted. In FIG. 5, a heater is installed on the side surface of the storage tank 10 as the heating means 8, but other conventional heating techniques can be used, and the installation position can also be designed as appropriate. In addition, it is possible to install a temperature sensor and operate the heating means 8 only when the temperature of the drainage B is outside the predetermined temperature range.

(caster)
The agitation processing apparatus 2 can be a fixed type, but can also be a movable type in which casters J are installed at the bottom as shown in FIG. In this case, the movement of the drainage treatment apparatus 1 is facilitated, which is preferable. Of course, the caster J can be rotatable or can be provided with a stopper.

(Disposition of drainage treatment equipment)
The drainage treatment apparatus 1 (including the stirring treatment apparatus 2 and the treatment agent apparatus 9) according to the present embodiment can be disposed at an arbitrary place. However, as shown in FIG. If it arrange | positions adjacent to A, the external discharge pipe 4 connected with the discharge port 12 can be shortened, and it is suitable. Alternatively, when the drainage treatment apparatus 1 is disposed directly below the sink R, the drain pipe W connected to the drain pipe T of the sink R and the pump P installed in the drain pipe T are not necessary, and the work space such as the kitchen is not narrowed. Therefore, it is preferable. In addition, various arrangements of the drainage treatment apparatus 1 can be selected.

[Embodiment of sink with drainage treatment device]
An example of the embodiment of the sink with the drainage treatment apparatus of the present invention will be described with reference to FIG. FIG. 6 is an overall view for explaining the sink 14 with the drainage treatment apparatus of the present invention.

  The sink 14 with the drainage treatment apparatus is obtained by attaching the drainage treatment apparatus 1 of the present invention to a sink that has been conventionally used. The sink may be an existing one or a newly created one, and is provided with a water tank 15 and a drain port 16 provided at the bottom of the water tank 15, and is connected to the drain port 16 as shown in FIG. It is also possible to provide a drain pipe 17 to be used. In FIG. 6, the water tank 15 is divided into two tanks, and accordingly, there are two drain ports 16 and two drain pipes 17, but the water tank 15 may be one tank or divided into three or more layers. According to this, one or more drain outlets 16 and drain pipes 17 can be provided.

  The drainage treatment apparatus 1 provided in the sink 14 with the drainage treatment apparatus is any of those described in the above-mentioned “first embodiment of the drainage treatment apparatus” to “third embodiment of the drainage treatment apparatus”. In FIG. 6, in FIG. 6, the agitation processing device 2 (including the discharge port 2 a), the processing agent container 3 (the container main body 3 a, the delivery path 3 b), the storage tank 5 (the first storage tank 51 and the second storage tank 52). , Partition wall 53), and float 7. In addition, the heating means 8 can be provided, or the treatment agent device 9 can be provided instead of the treatment agent container 3. 6, as in FIG. 3, the storage tank 5 is divided into two tanks, a first storage tank 51 and a second storage tank 52, by a partition wall 53, but is not limited to this, and one tank may be three or more layers. It can also be.

  The components constituting the drainage treatment apparatus 1 provided in the sink 14 with the drainage treatment apparatus may be integrated with each other, such as being housed in the same case. For example, only the treatment agent container 3 may be separately provided. Can also have an integral structure. In addition, as shown in FIG. 6, the drainage treatment apparatus 1 can be arranged directly below the water tank 15 to allow the drainage B from the water tank 15 to flow directly into the storage tank 5, or the drainage treatment apparatus. 1 may be disposed adjacent to the water tank 15, and the drainage B from the water tank 15 may be pumped up to the storage tank 5 by a pump or the like.

  The drainage B is discharged to the grease strap A through the external discharge pipe 4 connected to the discharge port 2b of the discharge means provided in the stirring processing device 2 (or the discharge port 5c of the storage tank 5 constituting the stirring processing device 2). It can also be discharged to the outside, such as a sewer pipe. On the other hand, in Japan, according to the provisions of the Sewerage Law (Article 12), it is obliged to discharge the effluent discharged from commercial kitchens after being treated with a septic tank interceptor (such as grease trap). In addition, the structure of this interceptor conforms to the standard related to the interceptor among SHASE-S established by the Air Conditioning and Sanitary Engineering Association, or the sewer business manager is equivalent to the standard of SHASE-S. It must be recognized as the above performance. Therefore, the drainage treatment apparatus 1 provided in the sink 14 with the drainage treatment apparatus of the present invention is equivalent to or better than the grease trap, that is, the performance conforming to the standard related to the interceptor in SHASE-S, or equivalent to this standard. If it has the above performance, it can discharge outside, such as a sewer pipe, without providing the grease strap A.

(Example of use)
Based on FIG. 6, the usage example of the sink 14 with a drainage processing apparatus is demonstrated. In the water tank 15, waste water B mixed with water from which dishes are washed, dust, oils and fats, etc. is collected and discharged from the drain pipe 17 through the drain port 16. As shown in FIG. 6, the two drain ports 16 are directed above the first storage tank 51 (left side in the figure) of the storage tank 5, and all the drainage B from the water tank 15 is the first storage tank 51. It flows down and is stored. When the storage capacity of the first storage tank 51 is exceeded, the drainage B overflows (overflows) over the partition wall 53 and flows into the second storage tank 52 and is gradually stored in the second storage tank 52. When the drainage amount measuring means 13 installed in the second storage tank 52 detects that a predetermined threshold water level has been exceeded, this signal is transmitted to the control means (not shown), and the stirring processing device 2 The suction operation by the suction means is started, and the drainage B in the second storage tank 52 is gradually sucked into the stirring processing device 2. At the same time, the processing agent in the container main body 3a of the processing agent container 3 is sucked into the agitation processing apparatus 2 through the inlet path 3b. In this way, the drainage B is agitated with the treatment agent added in the agitation treatment apparatus 2. Note that, based on the temperature of the drainage B measured by the temperature sensor, the drainage B can be heated to an appropriate temperature in advance by the heating means 8 (not shown in FIG. 6). When a predetermined time has elapsed from the start of the drainage process, the suction operation by the suction means of the agitation processing device 2 is stopped, and when a predetermined time has passed, the liquid is discharged through the external discharge pipe 4 connected to the discharge port 2b of the discharge means. B is discharged to grease strap A (or to the outside of drainage treatment apparatus 1 without passing grease strap A). If necessary, the on-off valve 6 provided at the bottom of the first storage tank 51 can be opened, and the drainage B (a state in which there is almost no oil or fat) can be discharged from the first storage tank 51.

[Combined use with grease trap drainage treatment equipment]
The drainage processing apparatus and the sink with the drainage processing apparatus of the present invention are capable of directly processing the drainage from the kitchen or the like, and when draining the treated drainage to the grease trap, No further processing is required. However, it is of course possible to further process the waste liquid in the grease wrap, and a waste treatment apparatus that performs this treatment (hereinafter referred to as the “gretrap effluent treatment apparatus” to distinguish it from the waste treatment apparatus of the present invention). Will be described below.

(Drainage treatment with conventional grease trap)
First, a normal draining process in the grease strap A will be described with reference to FIG. When the drainage B (usually containing dust) generated in the kitchen or the like is discharged into the grease trap A, the dust contained in the drainage B is collected in the basket C in the grease strap A. Several partitions D are provided in the grease strap A, and the flow rate of the drainage B is thereby reduced. Therefore, the fat and oil E, in which glycerin and fatty acid are combined due to the difference in specific gravity, has a moisture F (usually sludge). Are separated downward. The separated water F is gradually discharged to the sewer and septic tank through the trap G.

  As described above, in the conventional draining process using the grease wrap, only the moisture F is discharged to the outside and the oil and fat E is separately processed. It is processed and discharged to the outside. More specifically, fat and oil E and water F are changed to fatty acids by chemical reaction (separated from glycerin). By using fats and oils as fatty acids, biodegradability is much higher than the fats and oils E itself.

(Example 1 of grease trap drainage treatment apparatus)
Hereinafter, a first embodiment of the grease trap drainage processing apparatus will be described with reference to FIG. In this embodiment, a saponifying agent is directly introduced into grease strap A, and waste liquid B is processed by grease strap waste treatment apparatus 100 shown in FIG. As shown in FIG. 8, the grease trap drainage processing apparatus 1 includes a pumping pump 102, a discharge pump 103, a dust remover 104, and a motor M housed in one case 105. The case 105 may be movable by attaching wheels 106 and a handle 107 to the bottom surface.

(Processing agent supply process)
A saponifying agent, which is a treatment agent, is charged directly into the drainage B in the grease trap A. The mixing ratio of the drainage B and the saponifying agent is preferably about 5: 1 from the viewpoint of soaping efficiency, cost, etc., but this ratio is changed depending on the degree of soiling of the draining liquid B. When the ratio is large and the amount of dirt is small, the ratio of the saponifying agent can be decreased.

  The saponifying agent used here is one that can make waste liquid B, in particular, fat and oil E in waste liquid B into a soap liquid (soap liquid), liquid, gel, powder, other For example, the product of the applicant (trade name “Clean Eco Flow”) or the like can be used. The main components contained in “CLEAN ECO FLOW” are fatty acid sodium, fatty acid potassium, coconut fatty acid jetanol amide, several inorganic substances, purified water, and the like. In addition, if the drainage B can be modified and is environmentally friendly, a surfactant, deodorant, neutralizing agent, or a mixture of two or more of these can be used in addition to the saponifying agent. .

(Mixing and stirring process)
As shown in FIG. 8, a connecting pipe 102a is connected to the pumping pump 102, and a pumping pipe or hose (hereinafter referred to as “pumping hose 108”) is connected to the tip of the connecting pipe 102a. The tip of 108 is inserted into the drainage B in the grease strap A. The pump M is driven by driving the motor M, and the waste liquid B supplied with the saponifying agent is sucked through the pump hose 108 and stored in the pump pump 102. The pumping pump 102 needs the ability to suck the drained liquid B in the grease strap A, and a vacuum capable of sucking and discharging the liquid, a submersible pump, a land pump, and any other electric pump can be used. Further, the pumping hose 108 is suitably flexible.

  The drainage liquid B stored in the pumping pump 102 is mixed and stirred with a saponifier by a mixing stirrer (not shown) provided in the pumping pump 102 to become a soaped liquid. When the mixing and stirring process is completed, the soaped liquid waste B is discharged into the dust remover 104 through a transfer pipe or hose (hereinafter referred to as “transfer hose 109”). As this transfer hose 109, a flexible one similar to the pumping hose 108 is suitable. The discharged waste liquid B in the soaped liquid state passes through the through hole 110 of the dust remover 104 and flows into the tray 111 and further flows down to the hose 112 connected to the lower portion of the tray 111. At this time, the dust that could not pass through the through hole 110 remains in the dust remover 104 and is later removed and collected.

  The soaped liquid drainage B flowing down the hose 112 is stored in the discharge pump 103. Thereafter, in a “discharge process” to be described later, the oil is discharged into the grease strap A through a discharge pipe or a hose (hereinafter referred to as “discharge hose 113”) connected to the connection pipe 103a of the discharge pump 103. As the discharge hose 113, a flexible one similar to the pumping hose 108 is suitable. When the waste liquid B in the soap liquid state is further mixed and stirred while being stored in the discharge pump 103, the soap liquid can be more reliably obtained.

  By providing the hose 112 with a filter H and allowing the filter H to flow down, the waste liquid B in the soaped liquid state can be filtered, decolored, and deodorized. As the filter H, a device that generates nanobubbles or micro / nanobubbles having an effect of removing dirt in water can be used. In particular, the nanobubbles and micro / nanobubbles generated by ozone have a very strong bactericidal and disinfecting effect, and their bactericidal ability is about 10 times that of chlorinated bactericides, and do not generate harmful substances such as trihalomethanes. There is also an effect. The arrangement location of the filter H is not limited to the hose 112 and can be appropriately selected so that the efficiency of filtration, decolorization, and deodorization is improved, and the number of arrangements can be selected as appropriate.

(Water quality measurement display process)
The effluent B in the soaped liquid state after the mixing and stirring step is subjected to water quality measurement by the water quality measuring instrument 114 shown in FIG. When measuring water quality, there are various measurement items. For example, the “Water Pollution Control Act (Ministerial Ordinance for Establishing Drainage Standards)” divides wastewater discharge standards into pollution status due to hazardous substances and pollution status other than hazardous substances. In the state of contamination by substances, 27 measurement items such as the contents of cadmium and its compounds, cyanide compounds and hexavalent chromium compounds are listed, and in the state of contamination by substances other than harmful substances, 15 items are listed. Table 1 lists the measurement items and the standard values for measuring the pollution status of substances other than hazardous substances, as stipulated in the “Water Pollution Control Law (Ministerial Ordinance for Establishing Wastewater Standards)”.

  The water quality measuring instrument 114 may be equipped with instruments that can measure all measurement items, but the water quality standards for wastewater vary depending on the municipality supervising, and depending on the discharge destination, water quality standards are arbitrarily set. In some cases, it is also possible to provide an instrument that can measure one or more measurement items. In addition, the water quality measuring instrument 114 can be installed in the middle of the discharge hose 113, in the grease trap A, in the discharge pump 103, and the like, and can be installed in one place or two places or more. Moreover, as shown in FIG. 8, it can be set as the structure which can be attached or detached easily to the discharge hose 113, such as making the water quality measuring instrument 114 into the attachment structure with a short pipe | tube and a flange with an attachment bolt. In this way, the water quality measuring device 114 can be easily attached and detached separately from the main body of the grease trap drainage treatment apparatus 100, or the water quality measurement device 114 is incorporated in the main body of the grease trap drainage treatment apparatus 100 in advance. It can also be a structure. The water quality measuring device 114 can be integrated with the filter H to reduce the size of the entire apparatus.

  Measurement values measured by the water quality measuring instrument 114 or measurement results by litmus paper (hereinafter collectively referred to as “measured water quality”) are transmitted to the monitor 115 by an information transmission means (not shown) and displayed. In addition, a reference value for each target measurement item or a judgment standard based on litmus paper (hereinafter collectively referred to as “reference water quality”) is input and stored in an information storage means such as a personal computer. Reference water quality information can also be displayed. That is, the measured water quality measured by the water quality measuring instrument 114 is transmitted to a personal computer, information is organized by combining the already stored measurement items and the reference water quality, and the result is transmitted to the monitor 115, so that the measurement item-measurement. Display the water quality-standard water quality. As described above, when the measurement water quality and the reference water quality are displayed in correspondence with each measurement item, the treatment state (contamination state) of the drainage B can be easily confirmed. If the monitor 115 includes information storage means, a personal computer is not necessarily required.

  The monitor 115 can display pass / fail judgment for each item instead of or in addition to the combination of the measurement item, the measurement water quality, and the reference water quality. This pass / fail judgment is calculated by a personal computer based on the reference water quality stored in advance and the measured water quality transmitted from the water quality measuring instrument 114, and the calculation result is transmitted to the monitor 115 for display. For example, if the measured water quality of the hydrogen ion concentration is within the standard water quality range, the display content will be blue (meaning OK) for the hydrogen ion concentration, and the suspended matter amount is the standard. When the water quality exceeds about 5%, it can be displayed in yellow (others, cautions, etc.), and when it exceeds the reference water quality extremely, it can be displayed in red (others, NG, etc.). In addition, it is possible to display pass / fail judgment by comprehensively judging from each measurement item.

  When a printer is connected to a personal computer or a monitor 115 having information storage means, the contents displayed on the monitor 115 can be printed. Printing and filing along with date, time, temperature, humidity, etc. will be useful for various analyzes and predictions, such as analysis of the optimum amount of saponifying agent according to the surrounding environment.

  The monitor 115 can be incorporated in the case 105 or the like so as to be integrated with the main body, or can be easily attached to or detached from the case 105 as a separate body from the main body.

(Discharge process)
The soap B drainage B that has passed through the water quality measuring instrument 114 is driven back by the motor M to the drain pump 103 and returned to the grease strap A through the drain hose 113 or the exterior of the grease strap A. Discharge into sewers and septic tanks. When the water quality measuring device 114 is installed in the middle of the discharge hose 113 or in the discharge pump 103, two or more discharge destinations of the discharge hose 113 can be provided, and the discharge destination of the drainage B can be switched according to the measured water quality. . That is, when it is determined that it matches the reference water quality, the discharge destination of the discharge pump 103 is switched to the sewer or septic tank, and when it is determined that it does not match the reference water quality, the discharge destination is switched to the grease trap A. This switching can be performed manually or an automatic control method can be adopted by providing a control device.

  If the water quality measuring device 114a for the grease strap A is installed in the grease strap A, the treatment state (contamination state) of the drainage B in the grease strap A can be grasped. The measured water quality measured by the water quality measuring instrument 114a is transmitted to a personal computer (or a monitor 115 equipped with information storage means), and the monitor 115 combines the measured water quality with the measurement items already stored in the personal computer and the reference water quality. Communicate to and display. If the drainage B in the grease trap A does not reach the target water quality, a series of drainage processes such as the treatment agent supply process, the mixing and stirring process, the water quality measurement display process, and the discharge process are performed again and displayed on the monitor 115 If the measured water quality of the measured water quality measuring instrument 114a has reached the target value, the drainage process is terminated. Whether or not to repeatedly perform this series of drainage treatment can be determined and operated by a person, but based on the reference water quality stored in advance and the measured water quality transmitted from the water quality measuring instrument 114a, It is also possible to perform automatic calculation by the control device based on the calculation result.
