【 摘 要 】

Water pollution is a serious problem in the development of society of China. The plasma technology is one of the advanced oxidation technologies which is an efficient method in wastewater treatment. In this paper the degradation mechanism of organic pollutants in water by plasma is suggested, which is the main chemical reactions and physical effects, the different types of discharge and the corresponding reactors have been mentioned, including pulsed discharge plasma reactor, gliding arc discharge reactor and contact glow discharge electrolysis plasma reactor, especially the reactions in dielectric barrier discharge plasma. The plasma combined with another oxidation reaction processes also are reviewed, including catalyst, Ultraviolet radiation and Fenton reaction combined with plasma reactor.
