摘　　要：人工湿地污水处理是由相互关联的基质、植物和微生物通过物理、化学、生物过程的协同作用完成的,它只需要投入极少的人力和能源,就可以去除有机污染物、营养物质、固体悬浮物、重金属物质,实现对生活污水、面源污染径流、农田废水、二级污水处理厂出水、河道末端水进行长期稳定的净化处理。目前,该工艺在郑州和成都得到了应用,均取得了很好的效果,然而人工湿地在城市水污染治理中还存在有机质积累、占地面积大、受季节影响等问题。人工湿地是耐用而高效的系统,不断完善人工湿地的设计、性能、操作及维护,将能够更有效地改善水质。The constructed wetlands for wastewater treatment system typically consist of soil matrix,plants and microorganisms,and through sedimentation,chemical precipitation,adsorption,and microbial interaction,it can significantly reduce trace organics,biochemical oxygen demand,suspended solids,nitrogen,phosphorus,as well as metals,while consuming little human labor and resources.And the primary purpose of constructed wetland treatment systems is to treat various kinds of wastewater including municipal,industrial,agricultural and stormwater.The paper analyses the application of constructed wetland treatment systems in Zhengzhou and Chengdu City for municipal wastewater treatment,points out the existing problems of the soil matrix accumulation,large working area and the affection of season change.With constant efforts dedicated to the design feature and operating process,we can achieve a bright outlook of alternative technology for wastewater treatment.
