Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an aeration device for sewage treatment. 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 existing Chinese patent "A Sewage Treatment Aeration Device" with a publication number of CN220283816U can drive the fixed frame to move horizontally inside the aeration tank by driving the transverse screw to rotate through a servo motor. During the horizontal movement, the air in the external gas tank is transported to the aeration head through the vertical pipe and the horizontal pipe, and then the air floats up to achieve the purpose of aerating the sewage. At the same time, during the horizontal movement of the fixed frame, the waterproof motor drives the roller brush to rotate, which can stir the bottom of the aeration tank, enhance the fluidity of the sewage at the bottom of the aeration tank, eliminate the dead corners of aeration treatment, and prevent impurities from settling at the bottom of the aeration tank, thereby ensuring the effect of sewage treatment.

[0004] However, in actual use, the applicant found that the bubbles generated by aeration would quickly rise to the liquid surface of the sewage and the contact time with the sewage was very short, which resulted in certain deficiencies in use. Therefore, we proposed an aeration device for sewage treatment. Utility Model Content
