Sewage treatment plays an irreplaceable role in maintaining the ecological environment of the earth and the survival and development of human beings. In the current sewage treatment process, an aeration device is used to decompose sewage to remove harmful gases such as odor and carbon dioxide in the sewage.

The aeration device is arranged on the support frame. The utility model belongs to the technical field of sewage treatment, and specifically refers to an aeration device for sewage treatment with uniform mixing that can mix air and activated sludge evenly and has a good aeration effect, solving the problems that the aeration effect of the existing aerator is poor, and it is difficult for the air sent by the aerator to be fully mixed with the activated sludge. Therefore, the sewage treatment effect is also poor.

[0004] In the process of treating sewage with the aid of an aeration device, there is an existing aeration device as described above. In order to make the mixing more uniform, it adopts the cooperation of a frustum of a cone and a spiral plate to realize the rotation and up-and-down displacement of the stirring structure. Since the installation position of the frustum of a cone is fixed at a specified position, when the frustum of a cone rotates, due to the poor linkage effect between the frustum of a cone and the spiral plate, the stirring structure of the equipment is prone to jamming during operation, and the transmission efficiency that the frustum of a cone can achieve is poor, resulting in a low driving conversion utilization rate of the equipment and limiting the stirring speed of the equipment.
