Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an aeration device for sewage treatment. Background Art

[0002] People need to use a lot of water resources in their daily production and life, which produces a lot of sewage. Some sewage contains more harmful substances and cannot be discharged directly. In order to alleviate the shortage of water resources on the earth and protect the ecological environment, sewage needs to be treated before discharge. The pollutants in the sewage need to be decomposed and removed during the sewage treatment process. A large amount of dissolved oxygen is required when removing pollutants in the sewage, so aeration is required. Aeration refers to the process of forcing oxygen in the air to transfer to the liquid.

[0003] An existing aeration device for sewage treatment usually uses a stirring device to mix the oxygen sprayed from the aeration head with the sewage to decompose and remove pollutants in the sewage. However, the aeration nozzle is exposed to sewage for a long time and is inevitably blocked by impurities in the sewage, requiring frequent maintenance, increasing the workload of workers and being inconvenient to use. In addition, the ordinary stirring device does not make the mixing effect of sewage and oxygen good enough. Therefore, it is necessary to propose an aeration device for sewage treatment to solve the above-mentioned problems. Utility Model Content
