不同类型人工湿地研究进展及应用现状

Research Progress and Application Status of Different Types of Constructed Wetlands

近年来,水环境污染问题的日益严峻使得全球水资源短缺问题更加突出,人工湿地因其低成本、生态化、景观化、建设便利等优势被广泛应用于污水处理中。本文总结了目前人工湿地的四种主要类型,分别为自由水表面流人工湿地、地下流人工湿地、混合流人工湿地和生态浮床,阐述了各类型湿地系统的优势、研究现状及实践应用,以期为污水生态化处理的应用推广提供理论支撑。

In recent years, the increasingly serious water environment pollution problem has made the global water shortage problem more prominent. Constructed wetlands have been widely used in sewage treatment due to their low cost, ecological, landscaping, and convenient construction advantages. This article summarizes the four main types of constructed wetlands at present, namely, free water surface flow constructed wetlands, underground flow constructed wetlands, mixed flow constructed wetlands and ecological floating beds, and expounds on the advantages, research status and practical applications of each type of wetland system. Provide theoretical support for the application and promotion of ecological sewage treatment.
