The main pollutant components of the urban sewage are basically substances which are easily decomposed by microorganisms, and in the urban sewage treatment process, the method of decomposing organic pollutants by using aeration, oxygenation and microorganism culture is the most common method. Aeration and oxygenation are the most important technical guarantee means in the operation of the urban sewage treatment process, so that the improvement of the efficiency of an aeration system has important significance on biological treatment effect and energy saving and emission reduction. The traditional activated sludge method and the processes of A/0, A2/0, AB, SBR and the like mostly adopt blast microporous aeration technology. The corundum aerator has better mechanical strength and long service life, is not easy to break under the action of external force, can ensure the aeration system to operate normally and stably all the time, can also be used in the environment with complex media, and is continuously favored by the industry through years of practice contrast. Corundum aerators were first developed starting with the uk import disc, but the disc has its own inherent disadvantages: there is an aeration dead zone (e.g. the entire tray floor) where mud is deposited directly on the surface of the tray when aeration is stopped and re-start will re-agitate the mud, which is more energy intensive than a tubular type and also prone to clogging. In addition, the aeration efficiency of the rubber diaphragm aerator, the polyethylene plastic or polypropylene fiber aerator and the brown corundum disc aerator is not as good as that of a pipe type, and the pipe type is the best choice under the condition that the tank capacity is limited and the required air quantity is large. Therefore, in recent years, the use of microporous corundum aeration pipes is increasing.

The existing aeration equipment comprises an air supplementing pump and an aeration pipe. The air supplementing pump fills air into the aeration pipe to make the aeration pipe aerate to the periphery. When the air supply is stopped, the sewage flows back to the pipeline of the aeration system and the air supplement pump through the aerator, so that the equipment is damaged.
