Embodiment 1

[0048] Water quality of wastewater from a pig farm in Guangxi: COD Cr : 4000±20mg / L, BOD 5 : 2500±20mg / L, SS: 2000±20mg / L, PH: 7;

[0049] Design the pig manure wastewater treatment process. The specific process is as follows. The pig wastewater first passes through the sump through the solid-liquid separation machine, and the separated wastewater enters the air flotation sedimentation tank for secondary deep solid-liquid separation. The scum on the water surface is scraped The machine scraped slag enters the sludge tank, and the sludge at the bottom of the settlement is discharged into the sludge tank through the sludge pump. The supernatant wastewater enters the regulating acidification tank, and is sent to the UMIC anaerobic reactor by the UMIC feed pump for anaerobic treatment. The biogas enters the biogas collection tank, the anaerobic effluent enters the air flotation device, the separated wastewater enters the ammoniation tank for ammonification, and then enters the pr...

Abstract

The invention discloses a system and a method for harmless treatment of livestock and poultry breeding wastewater. The system comprises a wastewater treatment system and a sludge treatment system, wherein the wastewater treatment system comprises a water collecting pool, a solid-liquid separator pool, an air flotation precipitation pool, an acidification pool, a UMIC anaerobic reactor, a circulation tower, an air floater, an ammoniation pool, a first precipitation pool, a nitrification pool, a second precipitation pool, an aeration pool, a third precipitation pool and a storage pool, wherein the water collecting pool, the solid-liquid separator pool, the air flotation precipitation pool, the acidification pool, the UMIC anaerobic reactor, the circulation tower, the air floater, the ammoniation pool, the first precipitation pool, the nitrification pool, the second precipitation pool, the aeration pool, the third precipitation pool and the storage pool are sequentially communicated. According to the present invention, with the method, livestock and poultry breeding wastewater is subjected to harmless treatment by using the UMIC dual internal circulation anaerobic reactor as the coretreatment component through the physicochemical and biochemical combined method, such that the concentration of the water pollutants after the treatment can reach the requirements of the Discharge Standard Of Pollutants For livestock And Poultry Breeding (GB18956-2001), the treated water can be directly discharged so as to be used for the irrigation of surrounding crops after the treatment standard is achieved, and a certain economic benefit is provided for the surrounding farmers.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a system and method for harmless treatment of livestock and poultry breeding wastewater. Background technique [0002] The centralized feeding method of factory production is conducive to improving the breeding technology, epidemic prevention ability and management level of livestock and poultry. Compared with the traditional method, that is, farmers' scattered feeding, it greatly improves production efficiency and feed conversion rate, reduces the production cost of livestock and poultry and improves the economy. However, this production method has caused excessive concentration of livestock manure and barn flushing wastewater, and has the characteristics of large wastewater volume, high concentration of nitrogen, phosphorus, and organic pollutants in wastewater, large changes in water quality, and complex components, which are extremely difficult to treat. If the o...
