Description

technical field [0001] The invention relates to a water treatment system and a method for treating water, in particular to a water treatment system for ozone-enhanced electric filtration and a method for treating water, and belongs to the field of water treatment systems and methods. Background technique [0002] Water pollution threatens aquatic ecological security and human health, and the development of efficient water treatment technologies and devices is of great significance. In recent years, ozonation and electrochemical water treatment technologies have been favored by people because of their simple operation and high efficiency. When the two are coupled, especially when carbon-based electrodes are used, the electro-ozonation reaction can be triggered, and a synergistic treatment effect can be achieved by generating highly active hydroxyl radicals. [0003] At present, in the ozone-based advanced oxidation water treatment, a big defect is that the ozone dissolved in...
