Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a sewage treatment aerator. Background Art

[0002] During the sewage treatment process, certain methods and equipment are used to force air into the sewage, so that the sewage in the pool comes into contact with the air and is oxygenated, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, preventing suspended objects in the pool from sinking, and strengthening the contact between organic matter in the pool and microorganisms and dissolved oxygen, thereby oxidizing and decomposing the organic matter in the sewage. This process of forcing oxygen into the sewage is called aeration.

[0003] The utility model with publication number CN215516806U discloses an aeration mechanism with uniform aeration for sewage treatment, including a sewage tank body, an exhaust pipe is arranged at the bottom end of the inner cavity of the sewage tank body, a connecting block is arranged at the upper end of the exhaust pipe, a fixed block is arranged at the upper end of the connecting block, a stirring rod is arranged at the top of the connecting block, threaded rods are arranged on both side walls of the inner cavity of the sewage tank body, a motor is arranged on one side of the threaded rod, and a blower is arranged at the bottom end of one side of the motor. In the above application document, the motor is turned on to drive the threaded rod to rotate, thereby driving the slide to move relatively, and the connecting block fixedly connected to the slide moves left and right, so that the brush cleans the surface of the aeration head on the aeration disk. The threaded rod is easily corroded by sewage when it is inside the sewage tank body, and sludge, impurities, etc. in the sewage are easily stuck in the threads of the threaded rod, resulting in unstable movement of the slide, which needs to be improved.
