Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to an electric filtration catalytic persulfate brine treatment equipment and a method for treating water by using the same. Background technique [0002] With the development of industrial and agricultural economy and the improvement of people's living standards, the problem of environmental pollution has become increasingly prominent. Water pollution control is crucial to the ecological security of the water environment and human health. Existing water treatment technologies and facilities can remove and degrade conventional pollutants in source water and wastewater to meet certain water supply and drainage requirements. However, for some refractory pollutants and new pollutants, the traditional water treatment process cannot effectively remove them, and the remaining pollutants in the treated water may pose a potential threat to the safety of the water environment and hum...
