摘　　要：为了提高脱氮效率,强化废水脱氮处理效果。在研究大量文献的基础上,深入探讨了人工湿地中主要的氮去除机理——硝化反硝化脱氮,分析了影响人工湿地脱氮效率的主要因素,如溶解氧、pH、温度、微生物、基质等,综述了人工湿地脱氮的现状,并提出了人工湿地脱氮的研究进展以及研究方向的主要方向:提高溶解氧含量,控制优化pH、温度等参数,增加微生物数量,研发新型高效的基质等。研究不足在于对近几年发展起来的其他脱氮技术,如短程硝化反硝化,同时硝化反硝化等未进行综述讨论,对脱氮反应动力学模型也缺少讨论,还需通过总结大量文献以及实验论证其他的脱氮技术,提出脱氮反应动力学模型。In order to improve nitrogen removal efficiency, strengthen the denitrification treatment effect of waste water, based on extensive literature, the author concluded indepth exploration of the major wetland nitrogen removal mechanism-nitrification nitrogen, analyzed the impacts of wetland removal efficiency of the main factors, summarized the status of wetland nitrogen, and proposed wetland denitrification research and research directions： improving dissolved oxygen, the optimum parameters such as temperature, pH and so on, increasing the number of microorganisms, development of efficient matrix, etc. The shortage was lack of discussing the other nitrogen technology, such as shortcut nitrification and denitrification, simultaneous nitrification and denitrification, also lack of discussion of nitrogen response model, still needed a large number of documents through the summary and the experiment which demonstrated the other nitrogen technology, proposed the nitrogen reaction model.
