The aeration tank is mainly composed of three parts: tank body, aeration system and water inlet and outlet. The tank body is usually made of reinforced concrete, and the planar shape is rectangular, square or circular. Aeration pipe, also known as compressed air aeration, is a new type of aeration facility, mainly used for injecting air or oxygen into water during sewage treatment process to promote biological treatment reaction and improve dissolved oxygen (DO) content. The existing aeration pipe does not have cleaning effect during use, which leads to blockage of the aeration pipe during long-term use, thereby affecting the aeration effect.
