摘　　要：水体中的氨氮含量过高,会导致水体富营养化,影响和破坏水体生态平衡。氨氮污染控制消减技术成为了水环境污染控制日益紧迫的重要课题,迫切需要开发经济高效的废水脱氮技术来治理被污染的水环境。本文讨论了传统生物脱氮的机理及存在的问题,介绍了短程硝化反硝化工艺的机理及优越性。The high ammonia nitrogen content in water could lead to eutrophication of water body, affect and destroy the water ecological balance. Ammonia reduction technology became an increasingly urgent and important issue in the control of water environment pollution. It was urgent to develop an economical and efficient technology for wastewater denitrification to control the polluted water environment. In this paper, the mechanism and problems of traditional biological denitrification were discussed, and the mechanism and superiority of shortcut nitrification and denitrification were introduced.
