Description

Odor reduction type livestock waste recycling device {Organic fertilizer production system using the manure odor removal}

The present invention relates to a resource conversion device that reduces bad odor from livestock manure and uses it to produce compost and liquid fertilizer.

In general, the amount of livestock waste discharged from livestock farms such as pigs is approximately 7 million tons per year, some of which is used as natural by-product compost, but most livestock waste cannot be composted or converted into general resources, and is generated during the production of milk products and beverage products. The by-products are reduced to sediment (sludge) by coagulants such as caustic soda, and about 10 million tons of waste and sludge, including harmful substances generated from papermaking and dyeing agents such as chemical dyes, are dumped in the ocean and on land every year. It has been the main cause of soil pollution and environmental sanitation. For several years now, the government has invested a huge amount of budget to install hundreds of thousands of livestock manure storage tanks across the country to liquefy livestock manure. However, most of the livestock manure storage tanks are stored as livestock manure. The idea was to ferment the manure by adding a fermenting agent or adding microorganisms to remove the foul odor from the manure and then make liquid fertilizer or compost to turn it into a resource.

However, in the livestock waste storage tank, nitrogen (N or NOX, etc.) contained in livestock waste, odorous gases such as ammonia gas, methane gas, and all kinds of bacteria increase, polluting the surrounding environment and causing discomfort to residents, causing environmental health and sanitation pollution. Some farms are attempting to turn sludge (red mud) or EM into compost for the purpose of removing odors using microorganisms, but they are dumped in the soil without fundamentally sterilizing bacteria, creating another waste. As environmental pollution occurs, in fact, most livestock waste storage tanks are not used and are left unused in rice fields, fields, orchards, etc., remaining as ugly waste due to corrosion such as oxidation. This causes the problem of wasting hundreds of billions of won in government budget. there is.

On the other hand, with the conventional technology regarding the excrement odor removal device, Korean Patent Publication No. 10-1023649 does not have an alternative to bacterial sterilization, which is the source of the odor, and all excrement stored in the excrement storage tank is removed from the excrement circulation unit (blower). ), it generates odorous gas and removes the gas (there is no alternative to bacteria), so it costs a lot and takes a long time to remove the odor. As a result, side effects such as causing the proliferation of bacteria occur, odor removal, toxic odor, etc. There is no alternative to the harmful effects on the human body due to forced exhaust of gas and the oxidation (corrosion) of products due to the toxicity of gas. This expensive mechanical device to be installed in livestock farms cannot be used for more than one year. Entry into the market is becoming extremely difficult due to existing problems.

As another conventional technology, in Korean Patent Publication No. 10-1820228, all of these mechanical devices and filters are modularized for efficient use of the multi-filtering and bacterial removal device for adsorption of odorous gases and bacteria. ) is proposed, but the installation cost of the device itself is very expensive and there is a limit in terms of odor removal efficiency, so in terms of a method of recycling livestock waste, there is a need for an economical and efficient method of removing odor and recycling it. It's getting bigger.

Korean Patent Publication No. 10-1820228 Korean Patent Publication No. 10-1023649

Figures 1 and 2 show a block diagram showing the configuration of an odor reduction type livestock waste recycling device (hereinafter referred to as 'the present invention') according to an embodiment of the present invention. FIG. 3 shows a structural plan conceptual diagram of the present invention of FIG. 2.

Referring to Figures 1 to 3, the present invention accommodates incoming waste in the raw water tank 110, separates and processes the received waste through a primary separation device (A) and a secondary separation device (B) to produce compost. and a waste treatment module (100) that supplies liquid fertilizer, and the solidified material separated through the dehydration process in the waste treatment module (100) is introduced and received, and mixed with microorganisms supplied from the liquid fertilizer (300). A composting module 200 that composts through a stirring process, a plurality of liquid fertilizer tanks 310, 320, 330 that receive organic polluted water formed during the dehydration process in the excrement treatment module 100 and perform liquefaction through gas supply. , 340) are arranged in a structure in which they communicate with each other, separating non-decomposable pollutants from the organic polluted water formed during the dehydration treatment in the excrement treatment module 100 through the discrimination and separation unit 135, A communication unit (a1, a2, It may be configured to include a deodorization module 500 that sucks the odorous gas in the internal space into an intake device via a3, a4, a5, and a6) and sends it to the deodorization tower (T).

The waste treatment module 100 includes a raw water tank 110 that receives and accommodates livestock waste (pork manure, livestock manure, chicken manure, etc.) flowing in from the outside, and a primary treatment system disposed adjacent to the raw water tank 110. It is comprised of a water tank 120 and a flow rate adjustment tank 130 disposed adjacent to the primary treatment water tank 120.

In particular, the waste treatment module 100 receives the waste (X) contained in the raw water tank 110, performs dehydration and deodorization, and sends the dehydrated primary contaminated water to the primary treatment water tank 120. , a primary separation device (A) for sending the dehydrated solid pollen to the mixing tank 210, and receiving the primary contaminated water from the primary treatment water tank 120, and centrifuging it to separate the secondary liquid component. It further includes a secondary separation device (B) that separates contaminated water and secondary solid pollutants, flows the secondary polluted water into the flow rate adjustment tank (130), and flows the secondary solid pollutants into the mixing tank (210). Allow it to be configured.

The operation of the excrement treatment module 100 is that, as shown in FIGS. 2 and 3, the excrement contained in the raw water tank 110 is stored in the raw water tank 110, and the excrement contained in the raw water tank 110 is separated from the primary separation device (A). Through this, dehydration and separation of solid pots and liquid components are performed, and the solid pots are sequentially moved to the mixing tank 210 of the composting module 200 and the agitated composting facility 220 to be implemented as compost resources. In this case, in the mixing tank 210, the solid pots and the compressed material obtained by compressing the microorganisms formed in the concentration tank of the present invention described later are supplied to the mixing tank and mixed, and stirred in the agitated composting facility 220 equipped with a stirring facility. Through this process, solid pollen can be converted into resources through fermentation and decomposition and odor removal can be achieved.

The primary separation device (A) performs the task of separating the excrement flowing in from the raw water tank 110 into solid pollen and primary contaminated water through a dehydration process.

Figure 4 is a cross-sectional conceptual diagram showing the structure of this primary separation device (A).

As shown in Figure 4, the primary separation device (A) receives the excrement flowing in from the raw water tank, separates foreign substances mixed with the excrement through stirring, and finely forms the particle density to maintain a certain viscosity. It lowers and allows dehydration and solid pollen separation to be performed in a colloidal state with high viscosity. This operation performs physical mixing at the screw member group inside the primary separation device (A), and at the same time, micro-vibration is applied to colloidal waste from a vibration applicator that applies ultrasonic waves to remove non-decomposable material that is unnecessary for the formation of liquid manure and compost. Perform work to separate and discharge foreign substances.

Specifically, referring to FIG. 4, the primary separation device (A) has a receiving space therein, and is disposed in a housing (H) that accommodates incoming waste (X) and the receiving space, and is disposed in the receiving space, A plurality of screw members that are implemented to rotate the screws (y1, y2) in the direction of the adjacent surface (Y) of a pair of adjacent screws to perform agitation of the manure (X) and at the same time implement forward and backward movement of the manure Groups (C1, C2, C3), vibration application parts (10A, 10B, 10C) disposed on the upper part of the housing (H) and irradiating ultrasonic waves to the surface of the excrement in the receiving space, on the upper part of the housing (H) Light irradiation parts (20A, 20B) are disposed and implement a deodorizing effect by reacting with the photocatalyst material part formed on the inner wall of the housing (H), and a discharge part (50) provided on the lower surface of the housing (H). A mooring unit 60 in which excrement mixed with deodorization and stirring is moored. It is disposed at the lower part of the mooring unit 60, so that contaminated water is moved to the lower part, solid pollen is stacked on the surface, and pollutants moored in the upper part. A filter unit (70) including a cylinder unit (60A) that presses in one direction and presses it along the surface of the filter unit, and a solid discharge unit (60B) that discharges the solid pollen remaining after being pressed to the outside, the filter unit. It may be configured to include a rotary separator 90 that receives contaminated water and fine solid pollen via (70) and separates the dehydrated and solid pollen through rotation.

In this case, as shown in FIG. 5, the plurality of screw groups (S) include at least three screw member groups (C1, C2, C3) in which a pair of screws (42, 44) are adjacent to each other. As provided above, each unit screw is implemented so that the screw rotates (y1, y2) in the direction of the adjacent surface of a pair of screws adjacent to each other, and has the function of performing agitation of manure and at the same time implementing forward and backward transfer operation. Perform.

Taking the central screw (C2) as an example, the rotation direction of the unit screw (42) on the left rotates clockwise (y1), and the unit screw (44) on the right rotates counterclockwise (y2). This will come true. That is, the pair of screws rotates in the direction of adjacent boundaries, pulverizing the manure and performing agitation. At the same time, as the screw rotates, the excrement moves back and forth inside, increasing agitation efficiency.

The arrangement and rotation structure of the unit screw of the present invention allows for continuous agitation while pulverizing excrement lumped by contaminants, thereby carrying out a physical purification process that maximizes the contact area with ultrasonic waves, which will be described later. enable it to be performed.

In the purification process, where livestock waste ranging from as few as hundreds of kg to as many as tens of tons of livestock is continuously introduced, the efficiency of removing pollutants is extremely low by simply adding microwaves and moisture.

Like oil pollution, this is mostly a situation where other pollutants (feathers, plastics, metals, etc.) other than excrement are aggregated. Maximize the direct contact area and contact time of the microwave to separate the pollutants from moisture and solid pollutants of excrement. A method is needed to do this, and at the same time as purification, moisture and harmful volatile gases are desorbed due to the thermal desorption effect, which is a characteristic of microwaves, and it is easy to remove bad odors caused by volatile gases in advance.

Odor gases such as volatile gases are disposed on the upper part of the housing (H) and react with the photocatalyst material portion formed on the inner wall of the housing (H) by the light irradiation portions (20A, 20B) to achieve a deodorizing effect. Make it possible to implement it.

The light irradiation units 20A, 20B can be arranged by combining various light sources such as UV light source, LED light source, and infrared light source. In a preferred example of the present invention, odor gas contained within the housing is sterilized through ultraviolet sterilization. Allows for deodorization and sterilization. For ultraviolet sterilization, a wavelength of 265 nm can be applied.

In particular, it is preferable to form a light coating material layer 30 on the inner wall of the housing H so that odor removal can be more efficient through reaction with the irradiated light of the light irradiation unit. This reacts with the photocatalyst material and the reflected light emitted from the light irradiation units 20A and 20B to achieve a strong deodorizing and sterilizing effect. This photocatalytic coating layer allows the filter member to be coated with either zinc oxide (ZnO), cadmium sulfide (CdS), tungsten oxide (WO ₃ ), or titanium dioxide (TiO ₂ ). In this case, ultraviolet rays are irradiated due to the lighting of the ultraviolet lamp or LED lamp, which is the light source constituting the light irradiation unit (20A, 20B) of the present invention, and the ultraviolet rays reflect or diffuse the excitation light on the inner wall of the housing or the surface of the excrement. It reacts with the photocatalyst coating layer and generates hydroxyl radicals. In this case, the hydroxyl radicals achieve a deodorizing effect on odorous substances generated internally through agitation of excrement and at the same time implement a sterilizing effect.

In the case of this deodorizing and sterilizing _action , ultraviolet rays are irradiated on _the photocatalyst layer (for example, TiO ₂ layer) and ozone (O ₂ ) and hydroxyl radicals (hydroxyl radicals, OH radicals, By generating hydroxy radicals, the hydroxyl radicals achieve excellent sterilization and odor removal effects.

The excrement mixture, which has been stirred and odor-removed through the light irradiation units (20A, 20B), screw, and ultrasonic vibration, is discharged to the mooring unit 60 disposed at the bottom through the discharge unit 50 operated by the operation of the opening/closing valve. It moves, and a mixture of liquid and solid components is held in the holding portion 60 for a certain period of time.

At the lower part of the mooring part 60, a filter part 70 having the structure shown in FIG. 6 is disposed, and the filter part 70 is a plate having a plurality of through holes 72 and a spacer member 74. With a shaped structure (P), solids of a certain size are filtered and contaminated water is passed through the bottom. In this case, a certain amount of solid content remains in the upper part of the filter unit 70, and this residual solid content crosses the mooring unit from one side to the other through the cylinder unit 60A disposed on one side of the mooring tube 60, The remaining solids are pushed toward the pressurizing part (60B), and through this operation, the contaminated water in the remaining solids is dehydrated once again and moves to the bottom. Thereafter, the pressurized portion 60B is opened and closed to discharge the pressurized solid content to the outside, and the discharged solid content is transferred to the mixing tank 210 described above in FIG. 3 .

Contaminated water (hereinafter referred to as primary contaminated water) that has passed through the filter unit 60 is input into the rotating separator 90 disposed at the bottom and undergoes a dehydration process once again. Although this is not shown, when the primary contaminated water moving to the lower part of the filter unit 60 is collected and flows into the inlet 98 of the rotary separator 90 of FIG. 7, there is a transfer screw (not shown) inside. It rotates through a cylindrical rotating part 92 provided with and undergoes a dehydration process at high speed. In this case, contaminated water (hereinafter referred to as 'primary contaminated water') is dehydrated and released through the plurality of through holes 91, and this primary contaminated water is transferred to the primary treatment water tank 120 described above in FIG. 3. The solid content (first solid container) inside the cylindrical rotating part 92 is transferred through the operation of the transfer screw and discharged through the discharge hole 93a. The first solid pollen discharged in this way is connected to a transfer pipe through the transfer hole 96a and is transferred to the mixing tank 210 in FIG. 3.

The primary contaminated water transferred to the primary treatment water tank 120 flows into the secondary separation device (B) and undergoes a high-speed centrifugation process to once again separate it into solid pollen and contaminated water.

Figure 7 is a conceptual diagram showing the configuration of this secondary separation device (B).

The secondary separation device (B) separates solid pollen and contaminated water according to the operation of the control lever (R) that receives primary contaminated water (Wa) and flows it into the centrifuge and the high-speed rotating screw (S) inside the centrifuge. The contaminated water is separated into light-liquid contaminated water (w1), medium-liquid contaminated water (w2), and solid pollen (w3) according to its specific gravity and discharged to the outside. This centrifugal rotation is implemented by the rotation of the drive motor (m) and the movement of the chain (C). This secondary separation device (B) can perform separation by applying various commercially available devices in addition to those shown in FIG. 7.

Hereinafter, light and heavy liquid contaminated water (hereinafter referred to as 'secondary contaminated water') via the secondary separation device (B) flows into the flow rate adjustment tank 130, and the process of liquefying or purifying this secondary contaminated water is performed. The configuration of the present invention will be described in detail with reference to FIGS. 2 and 3. (In FIG. 3, the notation 'M' denotes a motor, and 'P' denotes a pump driven by a motor.)

As shown in Figures 2 and 3, some of the secondary contaminated water flowing into the flow rate adjustment tank 130 flows into the liquefaction module 300, and the remaining portion flows into the purification discharge module 400. ) to allow purification and discharge.

Specifically, referring to FIGS. 2 and 3, the liquefaction module 300 separates the secondary contaminated water stored in the flow rate adjustment tank 130 and sequentially receives the first to fourth liquefaction tanks ( 310, 320, 330, 340) are arranged sequentially adjacent to each other, and adjacent to the fourth liquid fertilizer tank 340, a high-concentration liquid fertilizer storage tank 350, a low-concentration liquid fertilizer storage tank 360, and a thickening tank 370 are sequentially arranged. It is implemented in a structure that

In particular, in this case, the first to fourth liquid tanks (310, 320, 330, 340) have communication parts (a1, a2, a3, a4, a5) that form a passage through which odorous gas moves in adjacent areas. , a6), the odorous gases can be formed to communicate with each other. As shown in Figure 9, the first to fourth liquid tanks (310, 320, 330, 340) are implemented in a structure in the form of a rectangular parallelepiped or cube in which the entire concrete material is sealed, and are adjacent to each other. It is arranged so that a communication part (a1, a2, a3, a4, a5, a6) that communicates with the adjacent liquid tank is formed on one side of each adjacent part.

Through the communication part, the above-described secondary contaminated water for forming the liquid fertilizer flows in, and at the same time, through the first to fourth liquid fertilizer tanks (310, 320, 330, 340), the odor generated from the secondary contaminated water It is implemented in a structure that allows mutual movement of gases. In other words, the liquid is located separately at the bottom of the liquid tank and the odorous gas is located separately at the top of the liquid tank, so when a certain amount of contaminated water is filled for liquefaction, the upper part is empty and filled with odorous gas.

The existence of such a communication part allows free movement of odorous gas filling the internal space between each liquid fertilizer tank and the liquid fertilizer storage tank and concentration tank.

In particular, in the present invention, although not shown, an aeration device that supplies oxygen to contaminated water containing a large amount of organic components can be disposed, making it possible to perform a liquefaction process for organic substances. This aeration device can supply air to the manure containing organic components, allowing microorganisms to be cultured in the manure.

Elements contained in manure include carbon (C), nitrogen (N), and phosphorus (P), but among them, carbon (C) has the lowest content, and because of this, microbial reactions may not occur smoothly. Therefore, by supplementing the carbon (C) that is lacking in livestock manure and adjusting the C/N ratio (carbon/nitrogen ratio) to an appropriate ratio, microbial reactions can occur smoothly. 50% of the liquid fertilizer content is carbon (C). By supplying phosphorus microalgae to the four liquid fertilizer tanks of the present invention, microbial reactions can be ensured to occur smoothly. The microalgae include blue-green algae Micricystis, green algae Chlorella sp., and Euglena gracilis.

Four liquid fertilizer tanks containing such aeration devices are arranged in series to sequentially allow cultivation and decomposition of microorganisms, and the contaminated water passing through the fourth liquid fertilizer tank is converted into low-concentration liquid fertilizer through the decomposition process of microorganisms. , the concentration is sequentially increased and converted into a high-concentration liquid fertilizer. The liquid fertilizer can be stored by dividing it into a high-concentration liquid fertilizer storage tank (350) and a low-concentration liquid fertilizer storage tank (360) according to concentration. In the case of the above-mentioned microorganisms, gases such as carbon dioxide gas and ammonia gas are generated due to the activities of the microorganisms, and odorous gases such as ammonia are dissolved back into the liquid fertilizer to some extent through the communication part, thereby realizing the effect. Additionally, the enrichment tank 170 allows microorganisms cultured in the liquid fertilizer to be separated and concentrated.

The separated microorganisms are transferred to the drug-free microorganism feeder 305, provided in the form of a microbial cake to the mixing tank 210 or the agitated composting module 220, and mixed with solid pots, causing bad smell through fermentation of the microorganisms. Significant additional removal of gas is possible.

In particular, in the present invention, through an odor communication line (P) connected to at least one of the fourth liquid fertilizer tank 340, the high-concentration liquid fertilizer storage tank 350, the low-concentration liquid fertilizer storage tank 360, and the concentration tank 370, The odorous gas inside the first to fourth liquid tanks (310, 320, 330, 340) is sucked in and transferred to the deodorization module (500). In the deodorizing module 500, the primary odor is removed through the primary separation device (A) of the present invention, and the liquid fertilizer tanks and liquid fertilizer storage tanks are arranged in communication with each other, so that the exhaust gas circulates and dissolves in the liquid fertilizer. This reduces the odor gas, and at the same time, the odor gas is sucked in at once through the communication line (P) through one intake pump and removed from the odor removal tower, so there is no need to install a separate duct line in each storage tank or treatment tank. Costs are significantly reduced, and the load on equipment can also be reduced.

In addition, referring to FIGS. 2 and 3, the purification discharge module 400 of the present invention receives secondary contaminated water flowing from the flow rate adjustment tank 130 and performs a process of rectification.

In particular, in this case, as shown in FIG. 3, the purification discharge module 400 separates the secondary contaminated water stored in the flow adjustment tank 130 and sequentially receives it into an anoxic tank 410, and the anoxic tank. Units 1 to 3 units (420, 430, 440) arranged sequentially adjacent to (310), a sedimentation tank (450) that receives contaminated water via the unit 3 unit (440) and performs sedimentation treatment; A first treatment tank 460 receives contaminated water via the settling tank 450 and performs purification treatment through a separation membrane, and receives contaminated water via the first treatment tank 460 and performs an R/O filter. It may be configured to include a second treatment tank 470 that performs purification treatment, and a reuse tank 480 that receives the contaminated water contained in the second treatment tank 470, stores it, and transfers it to a discharge or reuse facility. Let it happen.

In the anoxic tank 310, denitrification reaction and organic matter decomposition are mainly performed, and anaerobic microorganisms are allowed to perform the decomposition process by adding photosynthetic bacteria, recycled water, and EMBC malt.

In the first to third unit tanks 420, 430, and 440 adjacent to the anoxic tank 310, organic components contained in the contaminated water are decomposed through aerobic microorganisms. Aerobic microorganisms that liquefy these organic substances are microorganisms that require oxygen for growth, and yeast, mold, lactic acid bacteria, and actinomycetes can be used.

In particular, in the present invention, the first to third tank tanks 420, 430, 440 and the sedimentation tank 450 are provided with communication parts b1, b2, b3, and b4 that communicate with each other. That is, the odorous gas in the internal space of the unit 3 tank and the sedimentation tank 450 is circulated and supplied to the unit 1 tank 410, so that some of the odorous gas is removed by contacting the contaminated water, and at the same time, the odor gas is partially removed from the unit 3 tank 440 and the sedimentation tank 450. The odor gas in the inner space of the sedimentation tank 450 is transferred to the inner space of the enrichment tank 370 through an intake pump, and the odor gas is moved from the enrichment tank 370 to the deodorization module 500, thereby increasing the efficiency of odor removal. so that it can be increased.

In the sedimentation tank 450, the contaminated water that passed through the No. 3 tank is settled, suspended matter is removed, and the contaminated water is sent to the adjacent first treatment tank 460, where the solid pollen and the contaminated water are separated again through a separation membrane in the treatment tank. Let it be done. The separated solid pollen is sent back to the mixing tank, and the separated liquid material is sent to the adjacent second treatment tank 470. In the second treatment tank 470, the liquid material in the case of the separation membrane is stored in the low-concentration liquid fertilizer storage 360 as described above. The liquid material is transferred to and at the same time, some of it is purified through a reverse osmosis system (R/O: Reverse Osmosis Systems) so that it can be discharged or reused as washing water.

In the present invention, the liquefaction process of contaminated water and the purification process can be operated simultaneously, so that the purified contaminated water can be reused as washing water, etc. to increase resource efficiency.

In addition, during the purification process, contaminated water can be used as a low-concentration liquid fertilizer through a separation membrane, and in the entire process of the liquid fertilizer process module and purification module, the gas in the space communicating with each other is not installed without constructing a separate exhaust facility (duct facility). can be dissolved in liquid to increase the efficiency of odor removal.

As described above, the technical idea of the present invention has been described in detail in the preferred embodiments, but the preferred embodiments described above are for explanation and not limitation. As such, a person skilled in the art will understand that various embodiments are possible through combination of embodiments of the present invention within the scope of the technical idea of the present invention.
