[0002] The purpose of sewage treatment is to make sewage meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment can be divided into three types according to its function: physical method, biological method and chemical method. In sewage treatment, the addition of chemicals is a very important link. Chemicals can improve sewage treatment efficiency, reduce treatment time, and reduce treatment costs. At the same time, they can protect treatment equipment and extend equipment life. However, when adding chemicals to existing sewage treatment devices, the position where the chemicals fall into the sewage is fixed, and the sewage and the chemicals cannot react fully and quickly. Therefore, a stirring mechanism is required to increase the fluidity of the chemicals and sewage. In order to ensure the reaction effect, long-term stirring is required, which increases the consumption of electricity and does not meet the requirements of energy saving. Utility Model Content
