Description

technical field

[0001] The invention relates to an aeration device. Background technique

[0002] In order to ensure the activity of the activated sludge in the sewage treatment tank, it is necessary to use an aeration device to supply oxygen or air to the aeration tank during the sewage treatment process. Aeration not only makes the liquid in the pool contact with air or oxygen to oxygenate, but also accelerates the transfer of oxygen in the air to the liquid due to the agitation of the liquid, so as to complete the purpose of oxygenation. In addition, aeration also has the purpose of preventing the suspension of the tank from sinking and strengthening the contact between the organic matter in the pool and the microorganisms and dissolved oxygen, so as to ensure that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. However, the function of the aeration device in the prior art is si...
