The main steps of wastewater treatment include pretreatment, filtration, disinfection, and chemical treatment. Firstly, in the pretreatment stage, impurities such as suspended solids, oils, and particles are removed through processes like sedimentation, clarification, or filtration. Then, filters are used to further remove fine suspended matter and particles. Disinfection is carried out to kill bacteria and microorganisms, with common methods including chlorination, ultraviolet radiation, and ozone oxidation. Finally, chemical treatment is applied to adjust the water's pH, control water hardness, and prevent corrosion and scale formation.
