Description

Technical Field

[0002] Aeration device refers to the equipment that supplies oxygen to the aeration tank during the activated sludge method of wastewater treatment. Aeration not only allows the liquid in the tank to 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, strengthening the contact between organic matter and microorganisms in the tank and dissolved oxygen, and oxidizing and decomposing organic matter in the sewage, thereby purifying the water quality.

A main ventilation pipe is vertically arranged in the aeration tank, and the air inlet end of the primary aeration component and the air inlet end of the secondary aeration component are connected to the main ventilation pipe respectively.
