摘　　要：同步硝化反硝化工艺同传统的生物脱氮工艺相比,可以节约氧和碳源的耗量,大大降低生产运行费用,具有很大的发展前途。结合国内外研究成果,从微环境理论、宏观环境理论和微生物学理论方面对同步硝化反硝化的产生机理进行了综述,并分析了同步硝化反硝化的实现条件和影响因素。同时,结合同步硝化反硝化技术在实际中的最新应用情况,对该技术需解决的问题及应用前景作了探讨。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 operating cost. According to the latest research findings on SND inboth domestic and abroad, the mechanism for SND was reviewed and analyzed in various aspects including macroenvironment and microenvironment theory as well as biology theory. Realization conditions and influencing factors of SND technology were analyzed in the paper. According to the latest applications of SND technology, some unsolved problems arid its prospects were also clarified.
