人工湿地是人为设计建造用于处理污水的工程设施，存在着系统水力负荷偏小、占地面积大、系统供氧不足、氮磷的去除效率偏低、易堵塞等弱点。人工快速渗滤污水处理系统（CRI）是污水土地处理法中的一种类型，系统基本的处理机理是有控制地将污水投放于特定渗滤介质的表面，使其在向下渗透的过程中达到净化污水的过程。实验研究了将CRI作为人工湿地系统的前置处理单元改善人工湿地易堵塞的问题，并对改善原因作了分析，得出利用人工快速滤与人工湿地处理系统组合后，可以有效地改善堵塞状况，同时较一般未设预处理设施的人工湿地可以较长时间运行的结论。

Constructed wetlands is a man-made works for wastewater treatment facilities.The disadvanta-ges of the system include small hydraulic load,large area,insufficient oxygen supply system,low remov-al efficiency of nitrogen,phosphorus and easy to plug etc.Constructed rapid infiltration wastewater trea-ting system (CRI)is a type of wastewater land treatment.The basic processing mechanism is sewage into specific surface of percolation medium to purify the wastewater.Experiment studied the CRI as pre-pro-cessing unit of artificial wetland system to improve the effect of artificial wetland easily blocked,and the improving reason was analyzed.It is concluded that use of CRI +artificial wetland treatment system, can effectively improve the congestion.Compare to constructed wetland without preprocessing facilities, the composite system can run for a long time.
