摘　　要：在总结潜流人工湿地相关试验研究和工程实践经验的基础上,从湿地植物、基质填料、微生物、溶解氧、水力学条件以及温度等影响因子出发,综合概述了潜流人工湿地对氮磷、有机和悬浮污染物等的去除机理,总结并探讨了影响因子的去污原理和效应,同时提出了需要进一步研究和探讨的问题,为潜流人工湿地系统的设计、运行以及最大化的处理污水提供了参考依据。Experimental research and practical experiences related to subsurface artificial wetlands are summarized. Decontamination mechanisms of subsurface artificial wetlands to nitrogen and phosphorus, organic and suspended pollutants are briefly introduced, from the angle of influential factors such as flora of wetlands, matrix packing, microorganisms, dissolved oxygen, hydraulic condition and temperature and so on. Decontamination mechanism and effectiveness of the influential factors are summarized and discussed. Meanwhile, issues that need further studies and discussion are raised that provide a reference base for the design and operation of wetland system and a way of maximizing wastewater treatment.
