While the industry is over developed, various fresh water resources such as rivers, lakes, underground water, wetland fresh water and the like are polluted, and the problems of shortage of the fresh water resources and pollution to human beings are increasingly serious. The capacitive deionization technology is a promising desalination technology, and utilizes the surface of a charged electrode to adsorb ions and charged particles in water, so that salts and other charged substances dissolved in the water are enriched and concentrated on the surface of the electrode, thereby realizing water purification. The capacitive deionization technology is widely applied to the desalination of brackish water or sewage at present due to good treatment effect, simple operation, low energy consumption and no secondary pollution.

The brackish water or sewage treated by the capacitive deionization technology has complex essential characteristics, and contains various pollutants such as microorganisms and organic matters besides inorganic ions, which means that the disinfection operation of the water body is also very important. When microorganisms and macromolecular organic pollutants exist in water, the circulation stability of the capacitive deionization electrode is affected, and the desalting capacity and the charge efficiency are reduced. In actual operation, a combined desalting and disinfecting treatment process is often needed to ensure efficient treatment of sewage, but the combined desalting and disinfecting treatment process results in a longer treatment process and larger equipment investment, and the sewage treatment work has a longer period and higher cost.
