Integrated efficient precipitation sewage treatment technology

The invention discloses an integrated efficient precipitation sewage treatment technology for high-concentration domestic sewage. The integrated efficient precipitation sewage treatment technology comprises the steps of making sewage flow into a regulating pond after the sewage passes through a course rack and a fine rack, then making the sewage flow into an anoxic pond and using an agitator to stir the sewage so as to prevent the sewage from precipitation, and making microorganisms in the pond subjected to denitrification and denitrification; using a lift pump located at the bottom of the anoxic pond to lift water in the anoxic pond to integrated efficient precipitation equipment which carries a power-free sludge return-flow system, an efficient biochemical system, and an efficient precipitation system. The integrated efficient precipitation sewage treatment technology has the advantages that degradation efficiency of pollutants is high, cost is low, operation is easy, the discharge amount of organic sludge
