It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering.

[0003] 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, prevent suspended objects in the pool from sinking, strengthen the contact between organic matter in the pool and microorganisms and dissolved oxygen, and oxidize and decompose the organic matter in the sewage. This process of forced oxygenation in the sewage is called aeration.

[0004] Most existing aeration devices have the air outlet located at the bottom of the sewage treatment plant. However, when the air outlet is blocked or requires maintenance, the sewage must be drained before operation can be performed, which is cumbersome and inconvenient and has certain limitations.
