Breeding wastewater treatment method

The invention relates to the technical field of sewage treatment, in particular to a breeding wastewater treatment method with high treatment efficiency, comprising three stages of pretreatment, biochemical treatment and advanced treatment, wherein the pretreatment stage comprises slag removal through a grid, adjustment of primary sedimentation and flocculation sedimentation; the biochemical treatment stage includes anaerobic treatment, and multi-stage biological contact oxidation treatment; and the advanced treatment stage includes decolorization treatment and membrane bioreactor treatment. The breeding wastewater treatment method of the invention has the beneficial effects of low comprehensive energy consumption, strong system impact resistance, small floor space and low cost, and the breeding wastewater treatment method can ensure smooth stable treatment of livestock and poultry wastewater, can alleviate the economic burden of farmers, and solves a pollution problem at the same time. 本发明涉及污水处理技术领域，具体地说是种处理
