A kind of breeding wastewater treatment process

Abstract

The invention relates to a breeding wastewater treatment process, which specifically includes the following process: S1. The breeding wastewater is collected into a sediment tank through a sewage pipe, and the solid feces residue is removed through a solid-liquid separator, and the liquid enters a black film biogas tank; S2. The water flow well measures the influent water entering the black film biogas digester, and distributes the water to the black film biogas digester to remove organic matter in the water; S3, the biogas slurry generated by the black film biogas digester is distributed to the algae purification tank through the lift pump, and put into the immobilized algae The reaction group removes nitrogen, phosphorus nutrients, heavy metals and refractory organic matter in the water body; S4, the effluent from the algae purification tank enters the intermediate sedimentation tank, realizes the separation of algae and water according to the action of gravity, and the sediment flows back to the algae purification tank; S5, the intermediate sedimentation tank The effluent water enters the aerated biological tank, and a microbial generator is installed in the tank to rapidly degrade the organic matter and biochemical sludge in the water through the generated microbial flora; S6, the clarified water from the aerated biological tank enters the storage tank.

Description

technical field [0001] The invention relates to a breeding wastewater treatment process, which belongs to the technical field of livestock and poultry breeding wastewater treatment. Background technique [0002] With the rapid development of my country's livestock and poultry breeding industry, my country's poultry meat, pork, and egg production continue to increase. Large-scale farms can reduce farm costs and increase economic income, but large-scale farms also cause excessive concentration of manure and urine , so that the surrounding environment of the farm is under tremendous pressure. Breeding wastewater has the characteristics of large displacement, high concentration of organic matter, and high content of nitrogen and phosphorus nutrients. The wastewater is often accompanied by pollutants such as disinfectant water, heavy metals, residual veterinary drugs, and various zoonotic pathogens, making it difficult to treat. The situation of farm wastewater pollution is very ...
