Background

The sewage treatment method commonly used at the present stage is an activated sludge method, specifically, activated sludge with active microorganisms is discharged into a sewage tank, then aeration is performed by using an aerator arranged in the sewage tank, so that the activity of the microorganisms is maintained (necessary oxygen is provided for the microorganisms), and pollutants in the sewage are degraded by using the active microorganisms.

Common aerators in the prior art include microporous aerators, jet aerators and rotary-mixing aerators. Among them, the microporous aerator is most widely used because it is characterized by easy installation and the best aeration effect, but the microporous aerator is easily clogged. The main cause of this blockage is: when the fan is started or stopped, negative pressure is generated in the pipe, the aerator is enabled to suck backwards, soil particles in the sewage tank are clamped into micropores of the aerator by the negative pressure, and the device is blocked.

There are also many aerators with anti-blocking function in the prior art, for example, CN202220861212.9, entitled anti-blocking aerator for water treatment, which discloses an anti-blocking aerator for separating impurities in sewage by a filter screen, and then driving a deflector to rotate by using a fluid (air flow) to be conveyed, wherein the rotating deflector scrapes the impurities attached to the filter screen. However, during normal use, the baffle will only clean some light impurities, such as algae, attached to the filter screen, but the baffle will not function due to the hard particles stuck in the filter pores under the influence of the negative pressure. Therefore, the problem of negative pressure can only be solved from the source.
