Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to an aeration tank for industrial wastewater treatment. Background Art

[0002] An aerobic tank is a sewage purification tank that has both anaerobic and aerobic microorganisms. Usually, an aerobic tank requires a large amount of mixed liquid and has a certain adaptability to changes in water quality and water quantity. The aerobic tank in the same city requires a certain amount of oxygen. An aerator is installed at the bottom. The aerator forces the oxygen in the air to be transferred to the liquid to obtain sufficient dissolved oxygen. Due to the large range of the aerobic tank, the aeration effect of the aerator may be uneven, resulting in slower treatment of pollutants in the sewage and reduced sewage sedimentation.
