[0002] Sewage treatment refers to the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. In the existing sewage treatment process, it is often necessary to send sewage into the interior of the reaction tank, and the reactants are put into the interior of the reaction tank to achieve sewage purification. However, during the use of the existing reaction tank, a stirring structure is often set to accelerate the reaction efficiency of the reaction tank. However, after the reaction is completed, the reaction tank often produces a large amount of flocs, and the setting of the stirring structure usually stirs the generated flocs again from the sediment, so that they spread throughout the water body, which leads to a decrease in the efficiency of the clear liquid extraction of the entire reaction tank.
