[0002] Aeration refers to the process of transferring oxygen in air to liquid forcibly, and the purpose is to obtain sufficient dissolved oxygen. In addition, aeration also prevents the sinking of suspended bodies in the pool and strengthens the contact between organic matter and microorganisms and dissolved oxygen in the pool, so as to ensure that the microorganisms in the pool oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen.

[0003] The current sewage treatment aeration mechanism has a single structure, and generally only blows air into the sewage through the aeration holes on the aeration pipe, which leads to insufficient mixing of the organic matter and microorganisms in the sewage with dissolved oxygen, resulting in poor aeration efficiency.
