[0002] Sedimentation tank is a kind of structure that is used to remove suspended solids in water by sedimentation. It is widely used in wastewater treatment. There are many types of sedimentation tanks, which can be divided into horizontal flow, vertical flow and radial flow according to the direction of water flow in the tank. In the process of water treatment in the sedimentation tank, sodium hypochlorite is usually added. As a chlorine-containing disinfectant, sodium hypochlorite can effectively kill pathogenic microorganisms in water. The bleaching and decolorizing effect of sodium hypochlorite mainly depends on its oxidation performance. In the sedimentation tank, sodium hypochlorite can oxidize the colored substances in the water, such as oxidizing divalent iron to trivalent iron, and then precipitating trivalent iron by coagulation and sedimentation, thereby completing the decolorization of water body.
