[0003] In Chinese utility model CN211141672U, an aeration device for sewage treatment is disclosed. The aeration device for sewage treatment has a stirring assembly for stirring the water body connected to a power assembly of a driving machine at the top of the stirring assembly. More gas is released by stirring, and the sewage is stirred by the stirring assembly to make the sewage and the bubbles mix more fully, thereby improving the aeration efficiency. At the same time, the gas is sucked in by the suction fan and then released to the bottom of the water through the aeration port, so that the sewage and the bubbles mix more fully. However, the aeration device for sewage treatment still has the following problems in use:

[0004] The aeration device for sewage treatment achieves aeration through a stirring device that is deeply embedded in the water body. However, the stirring device is deeply embedded in the water, causing the water flow to stir inside the water body, but it is difficult to stir up waves, and the water surface fluctuates less, resulting in poor contact between the water body and the air. In addition, the position of the gas pipeline is fixed, resulting in the gas not being evenly dispersed, affecting the aeration effect. Utility Model Content

[0008] Preferably, from any of the above schemes, the plurality of water-repelling blades on the outer walls of the plurality of rotating air pipes are arranged in an interlaced manner, and the plurality of water-repelling blades are arranged in a radial annular array around the center of the rotating air pipe.

[0009] The technical effect achieved by adopting the above scheme is: a plurality of water-displacing blades can strike alternately to prevent the whole from being pushed and moved due to the same stirring direction, while improving the uniformity of water surface fluctuations.

[0010] Preferably, any of the above schemes has the plurality of rotating air pipes and water-displacing blades whose distribution lengths and widths are matched with the length and width of the inner wall of the fixed frame, and the rotating air pipes are located below the waterline of the floating block.
