It can be divided into a purification and discharge unit 30 that receives some of the manure from which the sediment is removed from the generating unit 20 and discharges it after purification.

First, the liquid manure generating unit 20 consists of a manure sedimentation unit, a liquid manure conversion unit, a liquid manure circulation unit, and a liquid manure storage unit according to the processing order.

The manure sedimentation section consists of a livestock circulation settling tank and a livestock circulation collection tank. The livestock circulation sedimentation tank receives livestock manure from the livestock house, removes the sediment in the livestock manure, and separates the raw water to be treated. The livestock circulation water collecting tank receives and stores raw water from the livestock circulation settling tank, and controls the amount of raw water supplied to the liquid fertilizer unit.

The liquid fertilizer unit receives raw water from the livestock circulation collection tank, removes organic matter, and removes odors to generate liquid fertilizer.

Specifically, as illustrated in FIGS. 2 to 6 , the liquid-encryption unit includes a liquid-encryption body 110 , a washing water tank 120 , and a washing water tank 130 .

The liquid fertilizer body 110 receives and stores raw water from the livestock circulation water collecting tank. And, as shown in FIGS. 2 to 3 , a jet pipe 111 from which air and raw water are jetted is installed to purify waste water on the inner floor of the liquid fertilizer body 110 . This spout pipe 111 is connected to the air supply pipe 112 installed outside the liquid liquefaction body 110, and the air supply pipe 112 is connected to the blower 113 to supply air into the liquid liquefaction body 110. do. And the raw water inlet pipe 114 is connected to the air supply pipe 112, so that raw water and air can be supplied together into the liquefied water body 110 through the jet pipe 111. And a treated water discharge pipe 115 through which purified raw water treated water is discharged is installed on the upper portion of the liquid fertilizer body 110 . In addition, a gas delivery pipe 116 connected to the washing water tank 120 is installed on the upper portion of the liquid-encrypting body 110 to deliver the gas generated inside the liquid-encrypted body 110 to the cleaning water tank 120 .

And in the interior of the liquid fertilizer body 110, a plurality of stage water prevention plate 101 that prevents the rise of air is installed up and down. A plurality of air holes 102 through which air can pass are formed in the single water prevention plate 101 . In addition, an air trap 103 for trapping the rising air is formed in the lower portion of the water stage prevention plate 101 . As such, a plurality of single water prevention plates 101 are installed inside the liquid fertilization body 110 so that the internal space of the liquid fertilization body 110 is divided into a plurality of spaces, and raw water and air move to the upper space through the air hole 102 . will do At this time, the air trap 103 formed on the barrier plate 101 of each stage can temporarily accommodate the rising air to increase the residence time, thereby enhancing the degree of activation of microorganisms.

In the liquid fertilization body 110 as described above, carbon and energy necessary for cell synthesis are obtained from dissolved organic materials, and raw water and air are supplied together and the raw water is liquefied using the metabolism of aerobic dependent bacteria using oxygen.

The washing water tank 120 and the washing water tank 130 are mounted on the upper part of the liquid fertilizer body 110 as a deodorizing device.

As shown in Figure 4 (a), the washing water tank 120 has a gas inlet 121 is formed on the side, a gas outlet 122 for discharging the deodorized gas is formed in the upper portion. The gas inlet 121 is connected to the gas delivery pipe 116 . A gas discharge pipe 123 is installed in the gas discharge port 122 to discharge the deodorizing gas to the outside.

And a partition wall 124 is installed inside the washing water tank 120, and the inlet space 125 in which the gas inlet 121 is formed and the gas outlet 122 in the inner space of the washing water tank 120 are formed. It is separated by a space 126 . The partition wall 124 is installed in an upper part of the washing water tank 120, and the washing water is filled in the lower part. The water level of the washing water tank 120 accommodated in the washing water tank 120 is preferably such that the surface coincides with the height of the lower end of the partition wall 124 so that the inlet space 125 and the discharge space 126 are blocked by the washing water. do.

In addition, a washing water nozzle 127 is installed in the upper portion of the inlet space 125 of the washing water tank 120 to spray the washing water into the washing water tank 120 . At this time, as shown in FIG. 4( b ), the washing water spreads in a planar shape by the washing water nozzle 127 and falls to an area larger than the area of the gas inlet 121 . Accordingly, the gas flowing into the washing water tank 120 through the gas inlet 121 passes through the washing water falling from the washing water nozzle 127 for the first time, and hydrophilic substances causing odor are removed. And the inlet space 125 and the outlet space 126 blocked by the washing water are blocked by the washing water falling from the washing water nozzle 127 causing waves to be generated on the surface of the washing water accommodated inside the washing water tank 120. The gas may move to the discharge space 126 by being temporarily connected according to the fluctuation of the washing water. Accordingly, the inlet space 125 and the outlet space 126 are repeatedly blocked and connected according to the fluctuation of the washing water. Since the gas cannot move to the discharge space 126 and is trapped in the inlet space 125 , an effective deodorization action can be achieved by increasing the stagnation time of the gas and the contact time with the washing water. In addition, in the inlet space 125 , as the washing water is sprayed through the washing water nozzle 127 , it collides with the washing water already accommodated therein, and the washing water becomes small particles and floats in the inflow space 125 , thereby deodorizing the gas. can increase

And as shown in FIG. 5 , a water level regulator 200 is installed in the washing water tank 120 . As shown in FIG. 6 , the water level regulator 200 includes a flange part 210 , a position control part 220 , a washing water supply valve 230 , and a ball top 240 . The flange portion 210 has a through hole 212 formed therein and is attached to the outer wall of the washing water tank 20 . That is, the flange portion 210 is coupled to the flange coupling portion 211 protruding to the outside of the washing water tank 20 . The positioning unit 220 is coupled to the flange unit 210 to block the through hole 212 . And the washing water supply valve 230 is mounted in the center of the position adjusting unit 220 to supply the washing water to the washing water tank 120 through the through hole 212 , and the ball top 240 is the washing water tank 120 . The washing water supply valve 230 is opened and closed according to the water level.

In the position control unit 220 , a long hole 221 is formed in the upper and lower portions with the washing water supply valve 230 as the center. And the position adjusting unit 220 and the flange unit 210 are coupled to each other by the coupling member 222 is inserted into the long hole (221). The coupling member 222 is a bolt protruding from the flange portion 210 and a butterfly nut coupled to the bolt. That is, the bolt protruding from the flange portion 210 is inserted into the long hole 221 , and the vertical position of the positioning unit 220 can be adjusted in a state in which the coupling between the bolt and the butterfly nut is loosened. The position adjusting unit 220 is limited in left and right movement by the bolt and can only move up and down. The operator may adjust the height of the ball top 240 by adjusting the vertical position of the position adjusting unit 220 . Accordingly, when the washing water is consumed at a fast rate due to evaporation of washing water, etc., the ball top 240 is raised to supply more washing water above a certain water level in the washing water tank 120, and in the opposite case, the ball top 240 is lowered. This can cause the supply of washing water to be cut off at a lower water level. As described above, the height of the washing water accommodated in the washing water tank 120 is preferably adjusted to the lower end of the partition wall 124, and when the water level of the washing water is higher, the residence time of the gas in the inlet space 125 is increased. The frequency and discharge amount of gas moving to the discharge space 126 is reduced, and when the water level of the washing water is lowered, the residence time of the gas in the inlet space 125 is reduced and the frequency and discharge amount of the gas moving to the discharge space 126 . this will increase

And a demister 128 is installed in the discharge space 126 to remove moisture from the deodorizing gas discharged. In addition, a connection pipe 129 connected to the treated water discharge pipe 115 is installed in the washing water tank 120 to discharge the washing water above a certain level to the treated water discharge pipe 115 .

As shown in FIG. 5 , the washing water tank 130 stores washing water and supplies the washing water to the washing water nozzle 127 . In addition, the washing water tank 130 may be connected to the washing water tank 120 by the recovery pipe 131 to recover and circulate the washing water contained in the washing water tank 120 .

The liquid manure circulation unit receives the liquid manure deodorized from the liquid manure conversion unit. And the liquid manure circulation unit sends the liquid manure back to the barn to circulate the liquid manure. According to this liquid manure circulation process, liquid manure is stored in the barn, and when the stored liquid manure exceeds a certain amount, it overflows and is transferred back to the barn circulation settling tank. And the liquid manure circulation unit sends unused liquid manure to the liquid manure storage unit.

The liquid fertilizer storage unit consists of a plurality of liquid fertilizer storage tanks, and receives and stores the liquid fertilizer from the liquid fertilizer circulation unit. During the off-season of liquefied fertilizer, liquid fertilizer is rarely used, so liquid fertilizer is stored in the liquid fertilizer storage unit, and liquid fertilizer is taken out and used when necessary.

The waste collection tank receives and provides raw water from the livestock circulation settling tank, and delivers raw water from which contaminants have been removed to the primary flow control tank. Alternatively, liquid fertilizer stored in the livestock house may be directly transferred to the waste collection tank by opening and closing a valve installed in the livestock house. The primary flow control tank delivers raw water from which fine particles have been removed to the secondary flow control tank. The primary flow control tank and the secondary flow control tank control the flow rate of the supplied raw water according to the purification and discharge conditions of the wastewater, and the secondary flow control tank supplies the raw water to the anaerobic tank. The anaerobic tank receives raw water from the secondary flow control tank. And the anoxic tank uses denitrifying bacteria in the anoxic tank and organic matter in the incoming raw water to convert nitrate nitrogen into nitrogen gas and reduce it to denitrify. As such, the anaerobic tank removes nitrogen from the raw water and then delivers it to the wastewater treatment unit 32 .

The wastewater treatment unit 32 includes a high-speed fermenter, a primary aeration tank and a secondary aeration tank. The high-speed fermenter is the same as the liquid fertilizer main body 10 of the liquid fertilizer. That is, the high-speed fermenter is the same as the liquid-encryption unit except for the configuration of the washing water tank and the washing water tank among the components of the liquid-encryption unit. The treated water purified in the high-speed fermenter is sequentially delivered to the primary aeration tank and the secondary aeration tank. In the primary aeration tank and the secondary aeration tank, the treated water is sequentially oxidized and decomposed by the action of aerobic bacteria by the air injected through the blower inside, and then the treated water is delivered to the organic matter removal unit 33 .

The organic matter removal unit 33 is composed of an after anoxic tank, a post aeration tank, and a primary settling tank. The post-anoxic tank receives treated water from the secondary aeration tank, removes nitrogen, and then delivers it to the post-aeration tank. The post-aeration tank removes organic matter that is not treated in the post aeration tank and then delivers the treated water to the first settling tank. In the primary sedimentation tank, the solid content in the treated water is precipitated and separated, and the treated water from which the solid content is separated is transferred to the primary chromaticity unit 34 .

The primary chromaticity unit 34 is composed of an iron chloride reaction tank, a neutralization tank, and a secondary precipitation tank. The iron chloride reactor receives treated water from the primary settling tank. In the iron chloride reactor, ferric chloride as a coagulant is added to react with the color material, so that the color material sinks in the form of sludge, and the treated water is discolored from dark brown to colorless. Thereafter, the treated water treated with color is transferred to the neutralization tank. In the neutralization tank, an alkali agent is added to neutralize the treated water. The secondary sedimentation tank receives the treated water from the neutralization tank, and separates and removes sludge and other fine particles remaining in the treated water. And the secondary settling tank delivers the treated water to the secondary chromaticity unit 35 .

The secondary chromaticity unit 35 is composed of an activated carbon reaction tank, a coagulation tank, and an activated carbon precipitation tank. The activated elastic reactor receives the treated water from the secondary sedimentation tank, and injects powdered activated carbon to adsorb fine suspended matter and color-causing substances in the treated water. The coagulation tank receives treated water from the activated carbon reactor, and aggregates the powdered activated carbon by introducing a coagulant. The activated carbon settling tank separates and removes the sludge generated by the agglomeration of powdered activated carbon, and then delivers the treated water to the filtration tank. In the filtered water tank, the treated water is delivered to the anti-leaking tank after removing the fine particles (SS).
