【Abstract】 This paper introduces the basic principle of two electromembrane processes: electrodialysis(ED) and electrodeionization(EDI), and summarizes the research on the removal of ammonia nitrogen and nitrate nitrogen from ED by studying the conventional operation, process comparison,variant technology and process integration. The research on the denitrification of water by EDI technology is discussed, and the prospect of denitrification by electrodialysis is discussed.更多还原
