Background

Aeration means artificially introducing air into the biochemical aeration tank through proper equipment to achieve the expected purpose. The aeration not only makes the liquid in the pool contact with the air for oxygenation, but also accelerates the transfer of oxygen in the air to the liquid due to the stirring of the liquid, thereby completing the purpose of oxygenation; in addition, the aeration also can prevent the suspension body in the tank from sinking and strengthen the contact between the organic matters in the tank and the microorganisms and the dissolved oxygen, thereby ensuring the oxidative decomposition of the microorganisms in the tank on the organic matters in the sewage under the condition of sufficient dissolved oxygen. The quality of the aeration device not only affects the biochemical treatment effect of sewage, but also directly affects the land occupation, investment and operation cost of a treatment field.
