摘　　要：人工湿地技术由于其显著减少了能源需求、经济成本和环境污染,已被全球采用作为绿色生态水处理技术之一。人工湿地污水处理技术具有相当高的污染物去除效率和生态效益。然而,人工湿地污水处理技术仍然面临诸多问题和挑战。首先综述了人工湿地污水生态处理技术的研究现状,重点从基质选择、植物优化以及水力调控等角度概括了目前相关技术的研究进展和存在的不足;同时,探讨了人工湿地功能强化技术的研究和发展重点;最后,结合我国“十四五”生态环境保护规划和我国乡村振兴战略所提出的目标和要求,探讨并展望了人工湿地污水处理技术在未来我国城乡水环境、水生态和水资源统筹协调发展中将发挥的重要作用以及未来科技攻关的方向。Constructed wetlands(CWS)technology has been adopted as one of the green ecological water treatment technologies in the world due to its significant reduction of energy demand,economic cost and environmental pollu-tion.Constructed wetland wastewater treatment technology has high pollutant removal efficiency and ecological bene-fits.However,constructed wetland wastewater treatment technology still faces many problems and challenges.This paper first summarized the research status of constructed wetland wastewater ecological treatment technology,focus-ing on matrix selection,plant optimization and hydraulic control,summarized the current research progress and exis-ting problems of related technologies.At the same time,the research and development focus of constructed wetland function enhancement technology were discussed.Finally,combined with the goals and requirements of the ecological environment protection plan of the fourteenth five year plan and the rural vitalization strategy of China,the impor-tant role of constructed wetland wastewater treatment technology in the coordinated development of urban and rural water environment,water ecology and water resources in the future and the direction of future scientific and techno-logical research were discussed and prospected.
