Abstract: The high voltage discharge can produce low-temperature plasma and induce both physical and chemical processes. The processing technology has the comprehensive action of high-energy electron，ultraviolet light，ozone etc. The technology that integrates light，electronic and chemical oxidation into one process has a good development prospect in wastewater treatment. In this paper，the degradation processes and mechanism of organic wastewater by low temperature plasma technology are introduced. The research status and development trend of pulsed corona discharge，dielectric barrier discharge，glow discharge and gliding arc discharge plasma for organic wastewater treatment at home and abroad are summarized. The current main existing problems include single treatment object orientedand high processing cost. In the future，the study about this technique should be focused on the optimization process，the reduction of the processing cost and energy consumption，so that this technology can be applied to practical wastewater treatment as soon as possible.
