[0037] The working principle and technical effect of the embodiment are as follows:
[0038] The pig manure sewage generated in the pig house is all flowed into the adjusting pool 1, and the pig manure sewage is collected in the early stage through the adjusting pool 1. Because the flow of the pig manure sewage is large or small, the pig manure sewage can be distributed through the adjusting pool 1. The pig manure sewage is flowed into the first pool 9 through the first connecting pipe 7. The bacteria liquid for fermentation is also sent into the first connecting pipe 7, and the pig manure sewage and the bacteria liquid are mixed and flowed into the first pool 9 through the flow in the first connecting pipe 7. Then, the oxygen is increased in the first pool 9 through the second oxygen increasing machine 8, and the fermentation is carried out. The oxygen increasing process is continuously carried out for 3.5 days, so that the odor of the pig manure sewage is reduced. Then, the oxygen is punched into the first pool 9 for 2-3 hours every day for about 20 days, so that the final water fertilizer is obtained. Then, the water fertilizer is sent into the dilution area of the second pool 13 through the third connecting pipe 10. Then, the water in the water collecting area on the left side of the second pool 13 is sent into the dilution area according to the amount of the water fertilizer, so that the water fertilizer is diluted. Then, the water fertilizer is discharged through the first discharge pipe 12. The water fertilizer can be sprayed through the pipe outside the first discharge pipe 12 or collected by the collector and manually sprayed. When the amount of the water fertilizer is enough, the pig manure sewage in the adjusting pool 1 is sent into the solid-liquid separator 24 through the second connecting pipe 25, so that the pig manure and other solid matters are separated. The sewage is flowed into the septic tank 21 through the branch pipe 23, so that the sewage is subjected to anaerobic treatment. The medicine can be added into the septic tank 21, so that the suspended matters in the sewage are flocculated. Then, the suspended matters are cleaned out through the air floatation machine 22. The sewage is treated in the septic tank 21, and then the treated sewage is sent into the third pool 16 through the fourth connecting pipe 20, so that the treated sewage is subjected to anaerobic, anoxic and aerobic treatments. The treated sewage is discharged from the second discharge pipe 15, so that the treated sewage is subjected to disinfection and other treatments, and then the treated sewage can be used for irrigation and other purposes. The solid matters separated through the solid-liquid separator 24 can be used as the fertilizer or some culture medium.
