Abstract: The min-review gives a brief introduction to contact glow-discharge electrolysis, a novel technique for wastewater treatment. The literatures concerning the basic principle are cited rather than the all, emphasizing on the degradation of organic pollutants in water. Now, the application is only limited in a small amount of water sample, the larger scale test has not been made. However, as a new method for purification of water, at least, the discussion is beneficial to the treatment of decentralized water or cellar water.
