[0002] In the process of sewage biochemical treatment, the role of aeration is to provide dissolved oxygen required for biochemical reactions to the microorganisms in the reactor, and to maintain sufficient mixing of the microorganisms, substrates and dissolved oxygen in the reactor, providing aerobic biochemical reaction conditions for microbial degradation. The quality of aeration not only affects the biochemical treatment effect of industrial sewage, but also directly determines the operating costs of the sewage treatment plant.

During use, the utility model can prevent excessive sewage containing sediment from entering the aeration pipe whenever the aeration pump is running, indirectly reducing the frequency of cleaning the inner wall of the aeration pipe.

[0004] Although the above scheme can prevent too much sewage containing sediment from entering the aeration pipe when the aeration pump is running, and indirectly reduce the frequency of cleaning the inner wall of the aeration pipe, during the aeration process, the bubbles generated will only flow upward from the aeration holes, so that the sewage in other places in the pool cannot contact the bubbles, resulting in uneven mixing of bubbles in the pool, resulting in reduced aeration efficiency; for this reason, we provide an aerated A / O integrated sewage treatment device to solve the above problems.

The rotation of the bevel gear 3 207 drives the bevel gear 2 206 and the bevel gear 1 203 to rotate relative to each other, thereby driving the rotating rod 201 and the rotating drum 204 to rotate relative to each other.
