摘　　要：从人工湿地的组成——基质、植物、水流方式,阐述人工湿地的去污机理,并综合国内外人工湿地的设计方法,对其关键因素进行分析,探讨人工湿地结构组成因素的选择及确定方法。综述结果表明,人工湿地的出现和发展为净化污水提供了一种生态思路,是未来水处理领域发展的一种趋势,但目前人工湿地的设计理论尚不完善,存在较大的改进空间。如何进一步改进人工湿地结构组成成分、优化设计方案依然是未来人工湿地设计需要解决的问题。Water environment pollution by human activities is one of the major factors leading to today＇s water crisis.Compared with traditional wastewater treatment technologies,constructed wetlands have expanded more rapidly due to various advantages that they have,such as low cost,simple maintenance,aesthetic and environmental friendly nature.Despite their rapidly increasing applications,the design of constructed wetlands needs significantly improvement towards more scientific,model-based approach,which is now an important issue of research and development.This paper investigates the mechanisms of pollutant removal in constructed wetlands that are directly affected by substrates,vegetations and water flow patterns.New,conceptual design methods are proposed,based on domestic and overseas experiences,and the impacts of several key design factors are discussed,to improve constructed wetland design.
