Technical Field

The invention relates to the technical field of pig farm environment treatment, in particular to a circulating treatment method for excrement and foul air of a pig farm water-soaking excrement ditch.

Background

Referring to fig. 1 and 2 for the structure of the present pig farm, the two sides of the pig farm are provided with slotted floors 2, a bubble excrement ditch a3 and a bubble excrement ditch b5 are arranged under the slotted floors 2, the middle part is a personnel passage 6, and a plurality of pumping fans 1 are arranged on the wall of the pig farm, so that the following technical problems exist: air purification in the pig farm is mainly based on air exhaust, and in order to achieve a good purification effect, a high-power exhaust fan needs to be configured, so that the energy consumption is too high in winter and summer. 2, the foul air exhausted by the exhaust fan mainly comprises hydrogen sulfide and ammonia gas, so that the foul air is heavy in odor, pollutes the environment and causes sound loading channel complaints by surrounding residents. 3, the water-soaking manure ditch needs to change water frequently for avoiding odor, the amount of sewage is overlarge, and the investment of treatment sites and equipment is large. In addition, sewage in the water-soaking manure ditches needs to be discharged to a sewage treatment plant for treatment after 2-5 months, and the sewage treatment plant needs to be provided with a water-fertilizer integrated treatment pool or a methane treatment device with the area and the capacity proportional to a large number of water-soaking manure ditches, so that the required site and the construction cost are huge.

At present, aerobic microorganisms are used for treating the water-soaked manure ditch, but an oxygen increasing pipeline and equipment are required to be arranged in the water-soaked manure ditch, so that the investment is large, the maintenance is difficult, and in addition, when the water-soaked manure ditch is used for increasing oxygen, noise and odor can be generated to influence the growth of pigs.

CN10787428A discloses an environment-friendly pig farm sewage treatment system and a using method and application thereof, sewage is treated by microorganisms, but the patent application has the following problems: 1, the sewage is treated after being smelly through the back-end treatment. 2, the equipment investment is increased, and the sewage treatment is carried out in a specific facility.

Disclosure of Invention

The invention aims to provide a method for circularly treating excrement of a water-soaked excrement ditch of a pig farm and dirty air, which mainly solves the technical problems that the excrement of the water-soaked excrement ditch of the pig farm and the dirty air need to be treated at the back end and the investment is overlarge.

The technical scheme of the invention is as follows: a method for circularly treating excrement of a water-soaked manure pit of a pig farm and foul air comprises the following steps of 1), designing the water-soaked manure pit a and the water-soaked manure pit b into inclined grooves; 2) two ends of the water-soaked manure ditch a and the water-soaked manure ditch b are provided with a transverse ditch and a treatment water pool, and the transverse ditch is an inclined groove; 3) partition walls are arranged in the treatment water pool and the pig raising area, and a plurality of roots blowers are arranged on the partition walls and are communicated below the liquid level of the treatment water pool through pipelines; 4) the treatment water tank is provided with a delivery pump connected with the water-soaking manure ditch a, and aerobic microbial bacteria are added into the treatment water tank.

Wherein the heights of the water-soaking manure ditch a, the transverse ditch, the water-soaking manure ditch b and the treatment water pool are sequentially reduced; and when the depth of the A end of the water-soaking excrement ditch a is 55cm, the depth of the B end is 60cm, the depth of the C end is 65cm, the depth of the D end is 70cm, and the depth of the E position is 120 cm.

The beneficial technical effects of the invention are as follows: the water-soaking manure pit of the existing pig farm is slightly modified to form a circulating flow, and sewage in the water-soaking manure pit statically flows from A to E and flows down. And aerobic microbial bacteria in the water flow decompose the excrement and urine at any time, grow and reproduce in the fresh excrement and urine, and treat the excrement and urine in real time, so that the excrement and urine of the pigs are discharged into water without chance to become smelly along with the whole growth process of the pigs, and the ambient atmosphere around a pig farm is improved. Dirty air in the pig farm is not discharged outwards, but is introduced below the liquid level of the treatment water pool through the Roots blower through a pipeline, so that the oxygen content and the temperature in the treatment water pool can be increased, aerobic microbial bacteria can propagate and grow, anaerobic bacteria can be eliminated, meanwhile, the dirty air is not discharged outwards, and the ambient atmosphere around the pig farm is further improved. The partition wall is arranged between the treatment pool and the pig raising area, and the interference of noise and peculiar smell to pigs can be reduced. Therefore, the odor source of the pig farm can be reduced by about 80%, the air exhaust amount of the exhaust fan can be about 50%, and the energy is saved. The water changing period of the water soaking manure pit can be reduced, the water changing period is prolonged to about 5 months, and the water consumption is saved. And the modification cost or the new construction cost is much lower than that of CN 10787428A.

Detailed Description

Referring to fig. 3, a method for circularly treating excrement of a water-soaked manure pit and foul air in a pig farm includes the steps of, 1), designing both the water-soaked manure pit a1 and the water-soaked manure pit b5 as inclined grooves; 2) two ends of the water-soaking manure ditch a1 and the water-soaking manure ditch b5 are provided with a transverse ditch 7 and a treatment water tank 4, and the transverse ditch 7 is an inclined groove; 3) partition walls are arranged in the treatment water tank 4 and the pig raising area, and a plurality of roots blowers 8 are arranged on the partition walls and are communicated below the liquid level of the treatment water tank through pipelines; 4) the treatment water tank 4 is provided with a delivery pump 9 connected with a water-soaking manure ditch a1, and aerobic microbial bacteria (purchased in the market) are added into the treatment water tank.

Wherein the heights of the water-soaking manure ditch a1, the transverse ditch 7, the water-soaking manure ditch b5 and the treatment water tank 4 are sequentially reduced; and when the depth of the A end of the water-soaking excrement ditch a is 55cm, the depth of the B end is 60cm, the depth of the C end is 65cm, the depth of the D end is 70cm, and the depth of the E position is 120 cm. After the device is put into use, water liquid with aerobic microorganisms is pumped into the water bubble excrement ditch a1 from the treatment water tank 4, and sewage in the water bubble excrement ditch flows downwards in an inclined way from the end A to the end B, from the end C and from the end D to the position E and statically flows. And aerobic microbial bacteria in the water flow decompose the excrement and urine at any time, grow and reproduce in the fresh excrement and urine, and treat the excrement and urine in real time, so that the excrement and urine of the pigs are discharged into water without chance to become smelly along with the whole growth process of the pigs, and the ambient atmosphere around a pig farm is improved. Dirty air in the pig farm is not discharged outwards, but is introduced below the liquid level of the treatment water tank through the Roots blower 8 through a pipeline, so that the oxygen content and the temperature in the treatment water tank 4 can be increased, aerobic microbial bacteria can propagate and grow, anaerobic bacteria can be eliminated, meanwhile, the dirty air is not discharged outwards, and the ambient atmosphere around the pig farm is further improved.
