摘　　要：统计分析表明,我国尾水湿地的应用发展迅速,尤其是近4年受国家和各省市发布的相关水环境治理政策的影响,尾水湿地数量呈爆发式增长。我国260座尾水湿地主要是由一种以上类型的人工湿地组合而成的复合湿地,以垂直潜流为主的尾水湿地对COD、氨氮、总磷的处理效果均较好且稳定,采用曝气、生物填料等强化措施的预处理系统,能大幅削减进入主体湿地的COD、氨氮污染负荷。为提高尾水湿地的处理效果,将其他强化脱氮除磷技术与人工湿地耦合联用已成为近年来的研究热点,多种强化净化技术已成功用于尾水湿地工程。According to the survey,the applications of constructed wetlands(CWs)used to treat effluent from wastewater treatment plants in China has increased rapidly,and it has exploded in the past four years,which may be due to the impact of relevant water environment governance policies issued by the country and various provinces and cities.Most of the 260 CWs were hybrid systems consisting of more than one type of CWs.The vertical subsurface flow system is very effective in the removal of chemical oxygen demand(COD),ammonia nitrogen and total phosphorous(TP),and it is more reliable than the other two systems.Pretreatment systems with enhanced measures,such as aeration and biofilm packing,can effectively remove COD and ammonia nitrogen.In order to achieve better nitrogen and phosphorus removal,integrating intensified nitrogen and phosphorus removal technologies with CWs has been drawing more and more attention and has been successfully applied in many engineering projects.
