Description

AO biochemical treatment pond of treatment sewage Technical Field The utility model relates to the technical field of sewage treatment, in particular to an AO biochemical treatment tank for treating sewage. Background The traditional AO biochemical treatment pond water distribution system design is crude, often causes sewage to flow into anaerobic pond and good oxygen pond evenly. The method has the advantages that the concentration of the sewage in the local area is too high or too low, the microorganism load in the high concentration area is too large, the treatment effect is poor, the microorganism activity in the low concentration area is restrained, the resource waste is serious, and the overall treatment efficiency is greatly reduced. In the aeration link, the unreasonable layout and aeration mode of the aeration device lead to uneven distribution of dissolved oxygen in the aerobic tank, insufficient dissolved oxygen in partial areas, affected metabolism of aerobic microorganisms, excessive dissolved oxygen in partial areas, and energy waste. Meanwhile, the aeration equipment is easy to block, difficult to maintain and high in operation cost due to frequent maintenance. When the treatment tank is operated, the sludge and impurities are easy to adhere to the wall of the aerobic tank, and over time, the dirt continuously accumulates, so that not only is the effective space in the tank occupied, but also harmful microorganisms can be bred to influence the water quality, and the manual cleaning difficulty is high, the cost is high, and the safety risk exists. Disclosure of utility model The utility model aims to provide an AO biochemical treatment tank for treating sewage, which solves the technical problems of uneven water distribution, poor aeration effect, easy accumulation of sludge on the tank wall and the like of the traditional AO biochemical treatment tank, and achieves the purposes of uniform water distribution, effective aeration and automatic cleaning of the sludge on the tank wall. The AO biochemical treatment tank for treating sewage comprises a treatment tank body, a water distribution aeration part and a stirring inner wall cleaning part, wherein an anaerobic tank and an aerobic tank are respectively arranged in the treatment tank body, the water distribution aeration part is respectively arranged in the anaerobic tank and the aerobic tank, and the stirring inner wall cleaning part is respectively arranged at the top and the inside of the aerobic tank. Preferably, the water distribution aeration part specifically comprises a fixed support frame fixedly arranged on the top outer wall of the treatment tank body, an anaerobic water level sensor arranged on the outer wall of the treatment tank body, an aerobic water level sensor arranged on the outer wall of the treatment tank body, a first supporting and fixing plate fixedly arranged on the outer wall of the treatment tank body, an electromagnetic valve drainage bent pipe communicated with the outer wall of the treatment tank body, and an electromagnetic drainage valve pipe communicated with the outer wall of the treatment tank body. Preferably, the sensing ends of the anaerobic water level sensor and the aerobic water level sensor are movably penetrated through the outer wall of the treatment tank body and respectively extend to the inside of the anaerobic tank and the inside of the aerobic tank, the bottom outer wall of the fixed support frame is provided with the communicating blocks at equal intervals, and the inside of the communicating blocks is provided with the communicating cavity. The anaerobic water level sensor and the aerobic water level sensor are arranged to monitor the water level conditions in the anaerobic tank and the aerobic tank in real time. When the water level reaches the upper limit, signals can be fed back in time, and the water inlet assembly (such as a water inlet connecting pipe and a water distribution pipe) is controlled to stop water inlet, so that the sewage is prevented from overflowing the tank body, and environmental pollution is avoided. When the water level is reduced to the lower limit, the water level sensor and the water distribution component (such as a communicating block, a water inlet connecting pipe and a water distribution pipe) work cooperatively, so that sewage can be reasonably distributed according to the water level condition in the tank, when the water level is lower, the water distribution speed and the flow rate can be properly increased, so that the sewage is uniformly distributed in the tank, and when the water level is close to the upper limit, water distribution is reduced, and the local water level is prevented from being too high. Thus, the contact area of the sewage and the microorganism can be increased, and the treatment effect is enhanced. Preferably, the top symmetry intercommunication of intercommunication piece is provided with into water pipe, the bottom outer wall equidistan
