Technical Field

[0001] The utility model relates to an aeration treatment device, in particular to a sewage treatment aeration treatment device, belonging to the technical field of aeration treatment devices. Background Art

[0002] Sewage usually refers to the discharged water from life and production that is polluted to a certain extent. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. In the sewage treatment process, people must use aeration treatment equipment to force air into the sewage, so that the sewage in the pool contacts with the air for oxygenation, and stir the liquid to accelerate the transfer of oxygen in the air to the liquid, prevent the suspended matter in the pool from sinking, and strengthen the contact between organic matter in the pool and microorganisms and dissolved oxygen.

[0003] Since the dust or particles contained in the air may clog the micropores in the aeration device, thereby reducing the aeration efficiency, people will install a filter plate at the air inlet of the blower. However, in real life, we know that there are often leaves or plastic garbage floating in the air. If they fall on the surface of the filter plate, if they are not cleaned in time, not only will the air intake efficiency of the aeration device be reduced, but also the normal operation of the aeration device will be affected. At the same time, in the prior art, the filter plate is mostly fixed and installed with screws. This will result in the filter plate being unable to be quickly disassembled and unblocked when it is severely blocked, thereby reducing the work efficiency of the staff. Utility Model Content
