[0002] Aeration tanks are biochemical reactors designed according to the characteristics of microorganisms. The degree of degradation of organic pollutants mainly depends on the aeration reaction conditions designed by people. Aeration tanks use the activated sludge method to treat sewage. The aeration tank provides a certain sewage retention time in the tank to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between sewage and activated sludge.

[0003] The aeration tank is mainly composed of three parts: the tank body, the aeration system and the water inlet and outlet. The design rationality of the aeration distribution structure will directly affect the sewage aeration treatment efficiency and treatment effect of the aeration system.

[0004] The existing technology has the following problems:

[0006] To this end, we proposed an air distribution structure for sewage aeration tanks to solve the above-mentioned drawbacks. Utility Model Content
