摘　　要：为解决污水脱氮中碳源缺乏,投加碳源易造成二次污染等问题,业界将目光投向自养反硝化脱氮技术。综述了常见的自养反硝化技术,特别是铁自养反硝化技术的发展。分析了铁基自养反硝化原理以及pH值、温度、Fe/Fe^(2+)浓度及存在形态、碳源等因素对反应过程的影响,阐述了铁自养反硝化技术及其耦合工艺的研究进展,并对铁基自养反硝化技术在应用过程中可能遇到的问题与技术发展方向进行了探讨。For insufficient organic matter in wastewater for denitrification and secondary pollution caused by adding carbon source,autotrophic denitrification technology is concerned by the industry.The development of current autotrophic denitrification technologies,especially by Fe-dependent,were summerized.Firstly this paper explained the concept and principle of Fe-dependent autotrophic denitrification,and analyzed the important influence factors on nitrogen removal of pH,temperature,Fe/Fe^(2+)concentration and form,and carbon source.Then different application ways and coupling process of Fe-dependent autotrophic denitrification technology was overviewed.Finally,the possible problems that maybe occurred in the future were discussed as well as the development direction of Fe-dependent autotrophic denitrification.
