【Abstract】 Simultaneous Nitrification and Denitrification(SND) biodenitrification technology has a lot of advantages compared with the traditional one in such aspects as saving carbon sources, decreasing upper aerating and realizing single stage bioden/trification, therefore there has been a great concern over the SND technology in the recent years. A survey is made on the current research status of SND in wastewater treatment both home and abroad, and the principles, characteristics, realization conditions and influencing factors of SND technology are illustrated. After analyzing the latest applications of SND technology, some unsolved problems and its prospects are also clarified.更多还原
