Description

Technical Field

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

[0002] Aerator is one of the important equipment in sewage treatment. It injects microbubbles directly into untreated sewage.

[0003] For example, a Chinese patent with publication number CN213060388U proposes an aerator for sewage treatment. The patent drives the rotating device through a waterproof motor, which can make the main aeration pipe rotate while revolving. By using the branch aeration pipe and the main aeration pipe, the water body can be effectively mixed and stirred, and the mixing of gas and water is promoted to improve the aeration effect. The main aeration pipe can continuously input gas during the rotation process through the connecting sleeve, and the revolution and rotation of the main aeration pipe and the branch aeration pipe can be coordinated to fully aerate the water body within the regional range, thereby improving the aeration area and efficiency. However, in this solution, since the sewage may contain a large amount of floating matter when the aerator is in use, a large amount of foam and floating matter may be mixed on the surface of the sewage when the sewage is aerated.
