Description

Organic Matter Composting System

The present invention provides an invention for producing food waste and various organic matter with high quality compost to prevent environmental pollution by various organic and to increase farm household income by producing organic products, as well as to prevent acidification of farmland. In particular, in the urban food waste treatment facility, residents are opposed to the construction of the food waste treatment plant itself, and the area of the facility is large to solve the problem that the construction site selection is not easy. In addition, to solve the problems that occur in the existing technology to provide a safe and efficient system.

The inventors of the present invention invented treatment system patents 215585 and 0258431 for composting food waste and manure. The above invention was applied to the 100 ton-scale processing facility technology contest conducted by Siheung, Gyeonggi-do in 1997, and was selected as the best technology and designed and constructed. The facility was constructed in accordance with the government's food waste composting policy, creating the first history registered in the fertilizer industry under the Fertilizer Control Act.

As a result of these efforts, the technology won the President's Prize in the 2001 Patent Technology Competition. In 2002, the Ministry of Government Administration and Home Affairs surveyed and evaluated the food waste recycling facilities built and operated by local governments nationwide. Siheung City, which received the award, received a prize of 60 million won on March 15, 2002. Currently, there are many composting facilities operated by local municipalities, but until now, only facilities registered under the Fertilizer Management Act have been constructed by applying the above patented technology.

The inventor has designed and constructed this facility and has been in charge of management operation since the completion. The present inventors had a lot of problems that could not be known without operating the facility for a considerable period of time. Especially, it is the problem caused by seasonal climate change and the quality change of food waste collected seasonally. The present invention is an invention for solving all these problems.

-The problem of storage hopper which is the first process of existing treatment system

In the first process of all food waste or organic resource recycling facilities, there is a hopper that has a function to input and store raw materials and a fixed quantity feeding device to send stored raw materials to the next process. The reason for storing a large amount of raw materials in the hopper is to solve the problem of waiting a long time for the collection vehicle and to provide a stable and continuous quantitative supply to the subsequent process. For example, the hopper storage scale, which handles 50 tons of food waste per day, operates two 25-ton storage capacity. However, in reality, even a single ton truck (3 tons) cannot be poured freely.

Looking at the actual situation, the collection vehicle enters the hopper slot, opens the loading door, and injects food waste according to the supply capacity of the quantitative supply device. In the case of a collection vehicle that collects 3 tons of food waste, the manager spends more than 20 minutes watching. This is because there is a problem with the collection of food waste. Unimaginable foreign substances (pork head, old pumpkin, hammer, paint can, clothes, tools, etc.) are secretly hidden in food wastes, which causes various problems in the metering device.

The design capacity of the food waste treatment plant hopper in Siheung City is designed and constructed with 25 tons of storage capacity, but it is impossible to store only 3 tons in 2 seasons. The reason for this is that Kimjang garbage, which occurs a lot in autumn, is injected and deposited at the bottom of the hopper to form a roof on a fixed quantity supply device.

At this time, the only way to solve this problem is to lift all 25 tons of hopper into the hopper.

Another problem in the use of the hopper, if the 25 tons stored in the hopper, regardless of the season, if the foreign matters are wrapped in a plastic bag, there is no problem, such as failure or inoperability in the metering device.

When explaining the structure of the hopper in detail, as shown in the model shown in Fig. 1, when the size of the upper inlet is 3m in width and width, it becomes narrower gradually as it goes to the bottom, so the specification of the bottommost part is narrowed to 1m in width and 1m in size. The metering device is installed. The hoppers that temporarily store organic materials and then link them to post-treatment are all designed and operated in this structure.

Looking at the problems in the use of such a structure, as described above, if foreign matters that cannot be supplied in a quantitative manner should be mobilized and scooped out of the fork lane. If garbage is collected and put in kimchi, it is a problem even if pig head is not put in. They freeze and squeeze each other under the hopper to form a dense, roofed roof over the metering unit. At this time, even if pressure is applied to the fork-lane from the top of the hopper, the common vegetables that do not disturb the roof is a problem that can not be easily understood. This phenomenon occurs frequently regardless of the season. Due to the two problems described above, the hopper is not using only 10% of the original design capacity.

-High concentration SS problem of wastewater from existing treatment system

There is another problem with food waste composting facilities. SS is being introduced into the sewage treatment plant in the dewatered wastewater. The water quality of the treated water of Siheung-si sewage treatment plant is low, but the COD is very high because it is a plant area, and the organic BOD is insufficient. Therefore, it is considered to be effective in wastewater treatment. . However, there is a problem that SS must be removed more than 95% in order to improve the general use of this technology.

-Problems of Composting Fermentation Field of Existing System

In addition, the problem of the compost fermentation field, which is the final task of the system, is indeed serious.

Taking Siheung as an example, the building is 20m wide by 40m high and 3m above ground and 2m underground. Looking at the available area of the compost fermentation in this compost fermentation site consists of a 10m horizontal 40m depth 2m. However, the depth of the compost layer is only 1.5m. Therefore, the actual available area is only 10m wide 40m long 1.5m. Therefore, the actual available area is less than 1/8 of the building. Especially, in the winter season, the fermentation surface during fermentation is so wide that the fermentation temperature is sharply deprived. However, such a building structure was inevitable because the stirrer is operating.

The present invention is to solve the above three problems to produce high quality compost at low cost.

Referring to the configuration of the present invention to solve the problems with the existing hopper described above Looking at the configuration of the first processing hopper (1) in the primary processing device (A), the crusher (2) is installed in the inlet, One side of the installed was configured to spray the water required for salt removal by fractionation.

Looking at the application of the crusher in the existing system, it is installed in the rear end of the metering supply device (5) to crush large foods such as bones, potatoes, radishes, apples and plastic bags, and at the same time discharge the food waste contained in the plastic bags to the outside It has been used to make. By the way, the purpose of the upper end of the hopper is a means for preventing the above problems caused in the quantitative supply device by crushing various large foreign substances such as pig head as described above. In addition, because the vegetable waste as described above can not be frozen and crushed to create a roof.

When the crusher is present in the rear end of the metering device as in the prior art, only the processed material that is metered in can be crushed, but when it is installed in the first stage as in the present invention, the pig head and the old bone pumpkin which are not accommodated by the metering device are crushed. It is possible to crush it and store it in the suit hopper.

In the existing hopper structure, the control device is configured to shut down the metering device when a chain is attached, such as a hammer or a tool, so that the breakdown of the metering device can be prevented, but it is necessary to lift all the raw materials stored in the hopper. Should be. However, in the hopper structure of the present invention, a crusher for shredding and breaking food waste at a high speed is located at the top of the hopper and is a process of discharging garbage from the car, so the person who gets off checks or stops the operation with the eyes. It can be easily removed immediately.

Looking at the practical effect of such a configuration, it is possible to shorten the time required to put more than 15 minutes in the existing three-ton collection vehicle in two to three minutes, and to put food waste using 100% of the hopper capacity and the lid (3) It has the advantage of being able to work safely and securely, and it is very easy to remove even if foreign materials such as a hammer are placed at easy distance and location for easy removal.

For example, it is possible to store 25 tons of hopper storage capacity of food waste treatment plant in Siheung-si, and it solves the inconvenience that people have to watch, and also solves problems such as autumn or vegetable waste and large food waste.

The deposition prevention device 4 is formed in the lower part of the hopper 1 which is the first process of the primary treatment device A of the present invention. The reason why the deposition preventing device is configured is an invention useful for an existing hopper that does not have a crusher on the hopper as in the present invention.

In addition, as described above to solve the problem that the roof is not made by making a roof in the fall season is to configure the deposition prevention device (4) on the upper portion of the fixed-quantity supply (5). Referring to the configuration of the deposition prevention device on the basis of the preferred embodiment shown in Figure 2, the prevention plate 42 constituted on the railway tracks consisting of two or more rails 41 integral with the hopper lower hopper body It is configured so as not to be separated from the silver rail, the surface of the prevention plate constitutes a needle bar 43, such as irregularities or candlesticks, the prevention plate back and forth reciprocating movement inside the hopper by the power transmitted from the oil pressure 44 from the outside of the hopper to the inside of the hopper. Or rotatable.

Looking at the practical effect of the above-described configuration constitute a flexible preventive plate in the rail 41 which is integrally formed with the hopper body so that the preventive plate is not separated from the track and the preventive plate is applied to the power transmission by the inlet 44 or rotation It can be reciprocated back and forth. In describing the practical effect of the above configuration, the organic material stored in the hopper prevents the deposition and pushes it to the bottom, so that the roof by the deposition cannot be formed.

Food waste is the main cause of sedimentation on slopes because food waste is entangled and supported. The present inventors anticipate that the above problems will occur when designing the Gyeonggi-do city facilities, and the problem can be solved by intermittently injecting high-pressure compressed air into a location where deposition may occur as a method to solve the problem. The idea was that the compressed air was designed to explode a large amount at a time. But it was not the same as the theory and failed. The reason for the failure was that a large amount of high-pressure air reacted to the food waste and the roof would be disturbed as the food waste was infested, but failed because the compressed air escaped to the wrong place such as a metering device.

In the hopper configured with the deposition preventing device 4 of the present invention, food waste or vegetable waste contained in the hopper cannot be formed because the roof cannot be deposited.

In addition, the fountain formed at the top of the hopper is sprayed for the deodorizing odor generated during the desalination and food waste input process. At this time, the amount of water used is 30% compared to the throughput, but the water quality can be used for sewage treatment plant wastewater, effluent and river water. In the above configuration, the food waste and water quantitatively supplied through the quantitative supply device 5 are dewatered by the dehydration device 6 installed after the quantitative supply device.

If food waste is produced in communal feeding centers such as restaurants without plastic bags, stones, ken, etc., which are not diluted, compost or feed, it can be linked to the process of dehydration and drying or fermentation in the dehydration apparatus of the above process. . However, the organic matter to be separated from the contaminants such as plastic bags was to remove the contaminants through the vinyl removal device, drum screen and sediment removal device that is a subsequent process of the present invention.

The dewatering device 6 of the present invention is configured to reduce the installation cost by applying a screw dehydrator and the wastewater generated during the dehydration process of the dewatering device 6 is to be treated by laying a conventional pressurized flotation separator 18. Configured. The dehydrated organic material is dehydrated in the dewatering device 6 after the quantitatively supplied organic matter is crushed by the crushing device. The waterproofing comb 9 corresponding to the secondary treatment device B is carried out by the transfer device 7. Is transferred to. The waterproof comb is set to be inclined to be driven by power and the vinyl removing device has a plurality of hooks on a rotating belt and has a fountain built in to easily separate the plastic bags caught on the hooks.

Looking at the practical aspect of the above configuration is that the hook of the vinyl removal device is rotated at the top of the waterproof comb, the plastic bag to be transported to the waterproof comb is caught by the hook and can only be rotated to the top. The hooked vinyl is separated from the hook by the hydraulic pressure of the fountain or a separate hook separator.

Determination of the amount of water supplied from the fountain configured in the vinyl removal device should be a capacity that can precipitate the precipitate in the deposit removal device. In addition, when the dewatering device 17 uses a high-speed rotational centrifugal dehydrator, the fluid should be pumped at least 200% of the throughput according to various experiments with the amount of water of the moisture content that can be pumped by the pump. The salinity of the mature compost was found to be less than 0.07% when 200% of the water was used. In addition, when the dewatering device 17 is designed by adopting the screen dewatering method, only 100% of the diluted water can be dehydrated. The residual salinity of fermented compost was found to be 0.3%.

After the plastic bag is sorted by the vinyl removal device, various foreign materials such as yakult bottles are impossible to separate from the drum screen or the vibration screen. The food waste, in which the foreign matter is sorted, is introduced into the sediment removing apparatus 11 together with the hydrolyzed water.

The sediment removal device 11 has a configuration in which the stirring blade rotates in the cylindrical body, and the ups and downs of the specific gravity are determined by the stirring blade rotation speed. When sediment that is not chainable or recyclable is precipitated, it is automatically separated by a sediment conveying device (12) consisting of a screw conveyor and configured to be transferred to a container, such as vinyl and glass fragments and chained shellfish that have already been separated.

The food waste from which the sediment is separated in the sediment removal device is introduced into the crusher 15 and the grinder 16 through a chute configured at the upper end of the sediment removal device, and the introduced food waste is pulverized into fine particles. The particles and water pulverized in this way are introduced into the dehydration apparatus 17 to be dehydrated.

The wastewater generated in the dehydration apparatus is a wastewater rich in organic matter, which is beneficial to the sewage treatment plant when the wastewater is introduced into the sewage treatment plant. The reason for this is that the BOD concentration of the influent flowing into most sewage treatment plants is far shorter than the sewage treatment design standard (150ppm to 200ppm) (investigated at an average of 70 to 80ppm), which causes problems in COD wastewater purification. It was confirmed that there is. BOD, which is a food for microorganisms, is low and COD is difficult to digest.

In order to activate aerobic microorganisms, BOD, which is a good oxygen supply and microbial prey, should be brought close to the influent design standard. The wastewater dehydrated in the aerobic pretreatment process, as well as the present inventor's research, has been confirmed by the users and researchers to be effective in the sewage treatment plant. However, the case of wastewater from anaerobic digesters is different. Wastewater from an anaerobic digester is due to the complete decomposition of organic matter by anaerobic microorganisms in the digester. The wastewater generated here is total nitrogen (T / N), which is the biggest problem for sewage treatment, which cannot be treated without advanced treatment facilities.

However, even in the wastewater generated in the aerobic composting facility, if a high concentration of SS is introduced into the sewage treatment plant, it is inevitable that the existing sewage treatment cannot be handled. Looking at the configuration of the present invention for solving such a problem it was configured to be dewatered wastewater flows into the pressure floatation separator (18). The configuration of the above-mentioned pressure injury separation apparatus adopts a conventional pressure injury separation method in which finely decomposed air particles float and float on a floating material. The sludge separated in the above configuration was mixed or dried with sawdust to produce an organic substance having a moisture content suitable for the fermentation environment, and then transported to a multi-food compost fermentation apparatus.

Wastewater from which SS is separated in the air pressure flotation device is introduced into the reservoir 19. The storage tank is configured in such a way that the wastewater generated during the working hours of the day may be stored and flowed into the sewage treatment plant uniformly for 24 hours. In most cases, the working time is 8 hours, so if it is introduced into the sewage treatment plant without a storage tank, it should be introduced during the working time, so it may be a problem depending on the size of the sewage treatment plant and the environment of the sewage treatment plant.

When explaining the process of dewatered cake in the above dehydration device, the dehydration rate of the dehydrated cake is about 75% depending on the performance and method of the dewatering device, but about 75% for most centrifugal dehydrators and about 80% for screw dehydrators. It became. However, the compost fermentation conditions for all organic matters must maintain a moisture content of 65% in summer and 10% oxygen at a moisture content of 60% ± 2 in other climates. If you continuously supply 60% water content and 10% oxygen to the throughput, fermentation will be the best, and it will be matured with high quality compost and there is no concern about odor. Therefore, the present invention allows to mix the dry or sawdust in a way to meet the fermentation conditions. However, depending on the dehydrating performance of the dehydrator can be changed as much. For example, if you apply a dehydrator with a dehydration rate of 60%, you do not need to use drying or sawdust.

The dehydrated cake 17 was dehydrated or dried by sawdust in the fine organic matter (SS) separated from the flotation separated by the flotation apparatus 18 to provide fermentation conditions suitable for fermentation.

Next will be described an invention that solves the problem with the above-mentioned compost fermentation device.

Looking at the configuration of the multi-stage compost fermentation system of the present invention that can be composted by high-speed fermentation of a large amount of organic matter, the fermentation chamber is formed in a vertical multi-layer and the composition of the wall of the fermentation chamber is completely sealed to the outside so that the external temperature does not affect It was. In the interior and the enclosed interior space, the compost fermentation chamber was composed of multiple layers, and the bottom of each fermentation chamber was configured with a dropping device 26. The quantity dropping device is composed of a plurality of rotatable shafts and at least four rotary blades 26b are formed on the outer circumference of the shaft. The rotary blades were formed in a structure in which compost drops downward in a certain amount at a predetermined time.

In addition, the one side of the shaft configured with the rotary blades was configured to rotate the metering device by the power transmitted to the shaft. In addition, the air supply unit 30 is formed on one side of the shaft so that oxygen can be supplied into the fermentation chamber through a vent formed in the shaft in a blower operated outside the compost fermentation plant.

Another configuration of the air supply device is to form an air supply device in the lower portion of the metering drop device and the air supply valve configured an air control valve for adjusting the air inflow amount.

When explaining the practical effect of the above configuration, in the supply of oxygen through the air control valve 30, the compressed air installed in the outside was to be the appropriate amount of oxygen supply for fermentation. The compost fermented in the first fermentation chamber 25 for a predetermined time by the air supply is dropped into the lower portion of the second fermentation chamber 27 by the operation of the fixed amount dropping device.

The multi-stage compost fermentation apparatus of the present invention will be described in more detail. The first fermentation chamber 25 is configured at the upper portion, and the height of the fermentation chamber is configured to be designed within a range in which oxygen supply is not a problem. The device 24 was configured. The configuration of the above-mentioned dispersing device constituted a plurality of pushers on a rotating body such as a belt or a chain. The above dispersion apparatus can be applied in various ways. For example, food waste is transferred to the top of the rotating belt, and a dropping device is arranged at regular intervals. When the dispersing device having such a configuration is rotated at the upper end, the food waste dropped to a predetermined position is evenly distributed and accumulated at the upper end of the first fermentation chamber and the fixed quantity dropping device 26. The food waste dispersed in the dispersing device is configured to allow high-speed fermentation to proceed by oxygen introduced in an appropriate amount through an air control valve configured in the air supply device of the air supply device configured at the bottom of the dropping device 26.

However, fermentation is impossible when the input compost is high in moisture content, so it is necessary to dry it at an appropriate moisture content. At this time, the drying device is configured separately, or as shown in FIG. 1, the hot air balloon is formed in the lower portion of the first fermentation chamber quantitative dropping device 27 to form a hot air device 31 for blowing heated hot air or a porous pipe such as a pipe. Compressed air was supplied by vertically or horizontally in the bottom of the dropping device and by heating wires at the inner circumference of the pipe.

The practical effect of the hot air device is that when forced air is blown from the outside, hot air is produced by the hot wire, and the hot air is distributed to the lower portion of the first fermentation chamber through the porous air outlet formed in the pipe and composted to the first fermentation chamber. The organics are dried while passing through the layers.

The configuration of the hot air device 31 will be described once again by the method of blowing hot air from the outside of the wall through the hot air device configured on the wall and the heating device inside the compost fermentation plant and blowing the compressed air from the outside. Looking at the practical effect of the above-described hot air device blows the heated hot air to the lower end of the quantitative dropping device 27, so that the energy efficiency is effective because it passes through the compost raw material accumulated in the first fermentation chamber.

In particular, food waste brought into the winter is frozen and brought in, so that the water content is very high even if crushed, crushed and dehydrated. If it is not dried, problems with fermentation will occur. Therefore, drying is very important in compost fermentation.

The compost raw material dried by the drying apparatus 23 or the hot air apparatus 31 starts fermentation in the first fermentation chamber 25. The raw material dried or fermented in the first fermentation chamber 25 is piled up again and fermented in the second fermentation chamber 27 by repetitive rotation of the dropping device 26. In this way, it is dropped to the third fermentation chamber 28 by the dropping device. Compost which passed through the 3rd fermentation chamber falls to 4th-6th fermentation chamber, and post-fermentation fermentation progresses. The compost fermented in this way falls to the composting discharge chamber 29 and waits for carrying out. In the composting fermentation chamber, each of the compost fermentation chambers was configured to measure humidity and temperature, and when the humidity was insufficient, a sprinkler was formed at the upper end of each compost fermentation chamber to sprinkle an appropriate amount to promote fermentation.

In addition, when looking at the oxygen supply amount of the compost fermentation chamber, the oxygen is consumed in the case of the first and second fermentation chambers 27 which are rich in organic matter and have a proper water content. However, in the case of the fourth and fifth fermented soybeans, when the oxygen supply is large, it is rather dry, which causes the fermentation. Therefore, the oxygen supply amount of the multi-stage compost fermentation apparatus of the present invention is different depending on each fermentation chamber. Each oxygen supply is calculated according to the composting fermentation method, but more accurate oxygen supply can be calculated by operating the facility to find the appropriate oxygen demand while checking the fermentation status according to the fermentation environment such as moisture content, temperature and humidity of the fermentation product. The air supply device 30 was configured to be easily supplied. Fermentation conditions for fermenting the organic matter is expected to be very easy to use the configuration of the air supply valve, the air supply device that can be adjusted according to the change as the fermentation environment changes with the season.

In addition, each of the fermentation chambers can be configured a stirrable stirrer and the configuration of the stirrer is to adopt the forward and backward stirring or vertical stirring method.

The multi-stage compost fermentation apparatus of the present invention produces a pilot plant and continuously feeds food waste while dropping it into the quantitative dropping device as a raw material accumulates in the first fermentation chamber by continuously supplying food waste. Otherwise, the ripe fermentation period is only 15 days.

In most cases, the compost raw material is put into operation for 8 hours, and the compost raw material accumulates in the first fermentation chamber, and the operating time of the dropping device is also operated for 8 hours. As a result of dropping by the device, there was more than 20 times the practical practical effect compared to the existing compost fermentation plant facility area. In addition, the multi-stage compost fermentation device also has the advantage that the agglomeration of the compost raw materials according to the general compost agitation does not occur, it was confirmed that the fermentation time is reduced by more than 50% compared to the conventional method.

In this manner, after the semi-completed or mature compost was discharged from the fermentation chamber by the discharge device 32 installed at the lower end, the fine contaminants were removed from the sorting device 33, and then configured to be packaged or unpacked according to the use.

If it is to be taken out to the farmers by unpacking, the discharge device 32 enters the lower part of the multi-stage fermentation device, and the car is opened at the lower part of the loading box. It was intended for convenience.

In addition, as a method for solving the odor generated in the fermentation room and the drying apparatus described above to form a odor suction line in each of the devices to transfer to a deodorizer such as wet deodorization method or soil deodorization method to solve the odor.

By explaining the practical effect of the above configuration, it is possible to completely solve the problem of complaint about odor by completely enclosing, to solve the fermentation obstacles caused by the outside temperature in winter, and 8 times more available than the available area of the construction area of your compost. Efficiency can be obtained.

For example, if you build an existing fermentation facility that composts 50 tons of food waste per day, you need a building 20m wide by 40m high and 5m high. However, the multi-stage compost fermentation apparatus of the present invention is sufficient to be 4m wide by 8m high and 15m high. Therefore, the construction site area can be drastically reduced.

As described above, if the moisture content of the organic matter is maintained at about 60% and evenly supplied with 10% oxygen relative to the throughput, the fermentation proceeds at a high speed so that organic matter such as food enters the ripening stage where no artificial oxygen supply is required within 7 to 10 days. do.

The composting stage of the compost can be fermented without oxygen supply and is independent of the outside temperature, so that the compost can be transferred to a field or paddy field to be used without having to use a compost fermentation plant and managed to avoid obesity with vinyl. The compost cooked by the smooth oxygen supply takes only a little time for fermentation without artificial oxygen supply in the ripening stage, but it does not produce bad smell or leachate.

In the multi-stage fermentation apparatus of the present invention, it is possible to provide all conditions necessary for fermentation, such as perfect oxygen supply and drying, so that it is possible to solve all complaints and problems caused by unfermentation.

In addition, when explaining the configuration of another invention in the configuration not shown in the drawings, the crushing of food waste at high speed and at the same time to separate the crushing and contaminant separation unit of the integrated crushing and contaminant separating apparatus formed on the top of the hopper and vinyl and A separation process to remove the contaminants was configured at the top of the hopper.

At the bottom of the hopper, a fixed-quantity supply device is configured, and a primary dehydration device is configured at the rear of the fixed-quantity supply device, and a magnet screening device is selected to select a chain glue on the upper portion of the transfer device for transferring the dehydrated cake from the primary dewatering device. It was. It is composed of a process of crushing and crushing the food waste passed through the transfer device to dehydrate and ferment the dehydrated cake.

If you introduce the system of the above system in order,

Crushing and debris separator → Storage hopper → Weighing device → Primary dewatering device → Feeding device equipped with magnetic separator → Wave, grinder → Secondary dewatering device → Fermentation device → Fine material removal device → Export

Looking at the practical effect of the above configuration, the various problems of the hopper can be completely solved by crushing and separating foreign matters before various organic materials are put into the storage hopper, and the amount of water due to sedimentation can be reduced by separating the chain paste by magnets. You can do it. Therefore, there is an advantage that can significantly reduce the amount of wastewater generated compared to the present invention shown in FIG. Therefore, the present invention can be usefully used in the construction environment of local governments that should minimize the generation of waste water.

In order to prevent the odor generated in the above-described configuration of the present invention, all the structures are configured to be sealed to the outside and the odor generated in the process of injecting the collection vehicle and food waste into the hopper, and the drying device and the fasting fermentation plant The odor was configured to be deodorized in the deodorizer (E) through the odor suction line.

It will be described another invention in solving the odor not presented in the drawings. The organic material treatment apparatus of the present invention generates a large amount of wastewater as a technique for washing salt using water. Therefore, the most efficient place as an installation site is located near the sanitary treatment plant installed in the sewage treatment plant. If the organic material treatment system is installed in the vicinity of the sewage treatment plant, deodorization lines are installed in the first and second treatment facilities and composting ridges, and a blower is formed at one side of the deodorization line, and the blower pipe is connected to the sewage treatment tank aeration tank again. .

Explaining the practical effect of the above-described configuration, by dissolving odor in the sewage treatment plant wastewater and supplying dissolved oxygen to the wastewater, it is possible to obtain the effect of one stone two tanks.

The main purpose of the organic and food waste recycling facility is to solve environmental problems caused by organic and food waste and to produce high quality compost. The government has banned landfilling since 2005 to solve the food waste environment problem. According to this policy, many local governments have constructed food waste recycling facilities. However, most facilities except Siheung City are actually aggravating soil pollution due to air pollution caused by odor, water pollution caused by leachate, desolation of farmland due to poor compost that has not solved salt, and landfilling due to excessive impurities. .

The present invention described above is a groundbreaking construction area by providing a multi-step compost fermentation device as well as solving the problems caused by large foreign matters, gluing inflow in the hopper and organic matter treatment system including food waste treatment facilities and SS contained in a large amount of waste water. To save.

In addition, the multi-stage compost fermentation apparatus of the present invention is expected to contribute to the production of organic products by preventing the problem of odors in a completely sealed and high-quality compost production.

Especially, it is an innovative invention to solve environmental problems of food waste in the city.
