Description

[0001] The utility model belongs to the technical field of sewage filtration, and specifically relates to a sewage circulation filtration device. Background Art

[0002] Wastewater treatment refers to the process of removing or reducing pollutants in wastewater so that it meets water quality standards for safe discharge or reuse. The goal of wastewater treatment is to protect the environment, reduce water pollution, protect human health, and achieve sustainable use of water resources.

[0003] Common sewage treatment includes the following processes: primary treatment: removing large particles and suspended solids by physical methods; secondary treatment: removing organic pollutants in sewage by biochemical reactions; disinfection treatment: in order to kill or remove residual pathogenic microorganisms, different impurities in sewage need to be separated and removed from sewage using different steps;

[0004] In the sewage treatment process, liquid chemical agents such as flocculants, disinfectants, and regulators need to be added to the sewage treatment device. Flocculants can cause tiny suspended matter and particles to aggregate, and then use ultraviolet sterilization after filtration. However, after adding the agent to the sewage treatment device, it is not convenient to stir the water in the subsequent sterilization area during the mixing of the agent and sewage, so that the bubbles or suspended matter in the water cannot be destroyed. At the same time, the microorganisms in the water may not be exposed to the irradiation area of ​​the ultraviolet lamp more evenly, thereby reducing the irradiation effect of the ultraviolet lamp;
