[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model. EMBODIMENT

[0018] Please refer to Figs. 1-3In this embodiment, an aeration assembly for sewage treatment includes a pipe structure 8 arranged in a sewage tank. A mounting pipe 3 is vertically connected to the pipe structure 8. A rotating pipe 7 is rotatably connected to the mounting pipe 3 through a sealed bearing. The rotating pipe 7 is connected to the pipe structure 8. The top of the rotating pipe 7 passes through and extends into the sewage tank. An aeration head 4 is fixed to the top of the rotating pipe 7. A fan unit 6 is fixed inside the rotating pipe 7. A plurality of blades 5 are fixed to the outer periphery of the rotating pipe 7 near its top. The pipe structure 8 is used to transmit input gas, and the input gas passes through the pipe structure 8, the mounting pipe 3, the rotating pipe 7 and the aeration head 4 in sequence.

[0019] During application, after the input gas enters the pipeline structure 8, the input gas will also enter the rotating tube 7 through the mounting tube 3, and pass through the aeration head 4 to form bubbles and be input into the sewage in the sewage pool. After the gas is input, the gas will act on the fan blade unit 6, and the circulating gas will drive the fan blade unit 6 to rotate, and the rotating tube 7 will also rotate accordingly. After the rotating tube 7 rotates, the blade 5 will also rotate. When the blade 5 rotates, the blade 5 will stir the sewage in the sewage pool and make the sewage circulate. The circulating sewage can make the bubbles generated by the gas transmission evenly distributed in the sewage, so as to improve the sewage treatment effect. Example
