Abstract

The invention discloses electric filtration catalytic persulfate water treatment equipment which comprises a liquid storage device, a persulfate adding device and an electrochemical filtering device.An anode and a cathode which are parallel to each other are arranged in the electrochemical filtering device, the internal space of the electrochemical filtering device is divided into a lower chamberlocated below the cathode, an upper chamber located above the anode and a middle chamber located between the two electrodes, and the edges of the two electrodes and an inner wall of the electrochemical filtering device are in a sealed state. The liquid storage device is communicated with the upper chamber of the electrochemical filtering device to form a circulating passage, and the persulfate adding device is connected with a liquid inlet passage of the upper chamber. A water outlet is formed in the bottom of the lower chamber of the electrochemical filtering device. The invention also provides a method for treating water by using the equipment. The water treatment equipment is ingenious in design, mass transfer of a reaction system can be effectively promoted, the water treatment methodis simple in process and high in treatment efficiency, and water treatment can be effectively, economically and environmentally friendly.

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...
