Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an aeration device used for water treatment. Background Art

[0002] The aeration device uses a blower or mechanical device to send air into the water. Through the diffusion and stirring of bubbles, the oxygen in the air is quickly transferred to the sewage. At the same time, it prevents the suspended matter in the pool from sinking and strengthens the contact between the organic matter and microorganisms and dissolved oxygen in the pool, thereby ensuring that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen.

[0003] During the sewage treatment process, an aeration device is placed in the sewage to provide the necessary oxygen supply. However, since sewage inevitably contains large particles of impurities, suspended matter and other pollutants, these substances tend to gather at the outlet of the aeration device, causing blockage problems, which in turn hinders the normal operation and efficiency of the aeration device. The traditional practice is to install a filter at the outlet of the aeration device to filter out these impurities and ensure smooth gas flow, but the filter and the device are often integrated. After long-term use, scale and other sediments will gradually accumulate on the surface of the filter, thereby reducing the filtration efficiency of the filter or even completely clogging it, which has an adverse effect on the aeration effect.

[0004] Therefore, an aeration device for water treatment is proposed. Utility Model Content
