摘　　要：人工湿地脱氮与其类型有着重要联系。不同类型人工湿地的构造、运行方式及复氧能力存在差异,因而脱氮效率有所不同。复合人工湿地的脱氮效率明显优于单一湿地系统。为了克服湿地脱氮中存在的不足,近年来涌现一批新型人工湿地,通过人工增氧、固定化微生物、电化学等新技术优化湿地构造、强化湿地脱氮过程。在总结不同类型人工湿地脱氮特性的基础上,重点分析各类型人工湿地脱氮效率的差异,并对今后的相关研究方向进行展望。Nitrogen removal in constructed wetlands(CWs) is closely related to its type. There remain some differences in construction,running mode and reoxygenation capacity of various CWs,thus nitrogen removal efficiency of various CWs is different. Nitrogen removal efficiency of hybrid CWs was obviously higher than that of single CW. In order to overcome the deficiency of nitrogen removal in CWs,new CWs sprang up recently and novel technology(aeration,immobilized microorganism,electrochemical,et al) was utilized to optimize the structure of CWs and strengthen the nitrogen removal process of CWs. On the basis of summarizing the nitrogen removal characteristics of various CWs, the differences among the nitrogen removal efficiency of various CWs were analyzed emphatically. In addition,the relevant research direction in future was prospected.
