[0002] In cities, it is also called a sewage treatment plant or sewage plant. A treatment station is often located in a factory. When the effluent is placed in the city drainage pipe, the treatment station is actually a pre-treatment facility. A wastewater treatment plant is a complex system composed of multiple unit processes. The cost and efficiency of each unit process are interconnected and affect each other, and ultimately determine the cost and efficiency of the entire system.

[0003] Aeration device refers to the equipment that supplies oxygen to the aeration tank during the wastewater activated sludge process. There are two main types of aeration methods: mechanical aeration and blast aeration.

[0004] In the dosing and mixing tank of the sewage treatment plant, liquid medicine is usually added to treat the wastewater. Aeration is a means of making air and water contact strongly, and its purpose is to dissolve oxygen in the air into the water, or to expel unnecessary gases and volatile substances in the water into the air. The pool provides a certain sewage retention time to meet the oxygen required by aerobic microorganisms and the mixing conditions for the sewage and activated sludge to fully contact. The existing technology has the following problems:

[0005] In the actual use of existing sewage treatment plant dosing mixing tanks, the dosing process in the tank is often done manually, which is laborious. At the same time, the sewage and the chemicals in the tank are not mixed thoroughly, so the chemicals cannot play their full role.
