[0002] Industrial wastewater refers to wastewater and waste liquid discharged during the production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with the water. It is an important cause of environmental pollution, especially water pollution. Therefore, industrial wastewater needs to be treated.

[0003] At present, when industrial sewage is treated, it is necessary to perform aeration treatment on the industrial sewage to promote the degradation of organic matter and the oxidation of ammonia nitrogen in the sewage, thereby improving the water quality. When aeration treatment is performed on the industrial sewage, aeration is generally achieved by compressing air through a centrifugal blower and passing the air through a pipeline to an aeration device in the sewage treatment system. However, when the sewage is aerated by a centrifugal blower, the air generated by the centrifugal blower sprays bubbles through the aerator, but the size and distribution of the bubbles are often uneven, resulting in better aeration effects in some areas and poorer effects in other areas, thereby affecting the redox process in the sewage.
