Advances in the Application of the Low Temperature Plasma Technology in Wastewater Treatment
The low-temperature plasma 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 research status and development trend of high-voltage pulsed discharge, dielectric barrier discharge, glow discharge for organic wastewater treatment at home and abroad are summarized. The current main existing problems include single treatment object oriented. 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.Key words: Low temperature plasma technology; High-voltage pulsed discharge; Glow discharge; Dielectric barrier discharge; Wastewater
