Description

technical field [0001] The invention relates to an aeration device for sewage treatment, which belongs to the field of sewage treatment equipment. Background technique [0002] With the intensification of our industrialization and urbanization, in recent years, my country's water pollution has become more and more serious. If these polluted water sources are directly discharged into rivers, they will directly cause serious pollution to rivers. . Therefore, under normal circumstances, it is concentrated and drained to the sewage treatment plant through pipelines, and can only be discharged into rivers after treatment. In the prior art, aeration is generally used to increase the oxygen content in sewage to reduce the content of anaerobic bacteria in sewage. The aerator head is the head-end part of the aerator. It is generally combined with the air supply pipeline connected to form a complete aerator. The aerator head is generally installed in the sewage tank, and the compress...
