Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an aeration tank for municipal sewage treatment. Background technique [0002] At present, the random discharge of sewage will have a great negative impact on the environment. People often use aeration tanks to treat sewage. The aeration tank is a structure that uses activated sludge method for sewage treatment. The system and the water inlet and outlet are composed of three parts. The pool body is generally built with reinforced concrete, and its planar shape is rectangular, square and circular; aeration is a means to make air and water come into strong contact, and its purpose is to dissolve oxygen in the air in water. The aeration structure of the aeration device is single, and the mixing of sewage and air is not sufficient, resulting in low aeration efficiency, and it is difficult to meet people's growing sewage treatment needs. Contents of the invention [0003] The t...
