摘　　要： 由于渗滤湿地污水处理系统具有很高的净化效率和相对较低的基建投资和处理成本 ,目前正渐渐在许多国家得到较为广泛的应用 .本文简要论述了渗滤湿地的构造与渗滤介质、N和P的去除过程与净化机理、技术性能、现行的设计方法、运行与调控机制、土壤堵塞问题与解决途径、垂直流与水平流人工湿地处理系统的组合及其在不同类型废水处理中的应用等 .最后 ,探讨了这一技术的研究发展方向 . As their high purification efficiency and relatively low capital investment and treatment cost, infiltration wetland wastewater treatment systems have been popular,and are being increasingly applied in many countries. In this paper, the bed structure and filtering media, nitrogen and phosphorus removal processes and purification mechanisms, performance, current design criteria, operation and regulation mechanisms, soil clogging problem and solutions, and combination of vertical-horizontal flow wetlands treatment system and its use in different types of wastewater treatment were introduced and summarized. Finally, the future research directions of this technique were also discussed.
