人工湿地类型的选择及案例分析

Type Selection of Constructed Wetlands and Related Design Case Analysis

人工湿地技术在我国污(废)水处理、黑臭水体修复、海绵城市建设、水源地保护等领域的应用日益广泛。确定人工湿地类型是人工湿地工程设计的首要步骤,不但关系到工程占地和相关污染物去除,还直接对工程造价、运行管理费用、生态景观效应等产生影响。总结了近年来国内工程实践中人工湿地的主要类型,分析了因地制宜进行人工湿地类型选择的要点及其对工程设计各方面的影响,并结合重庆市某水源地保护湿地实际工程设计,探讨了人工湿地类型选择中方案比选的思路,以期为我国人工湿地相关工程设计提供一定的借鉴。

The constructed wetland technology has been widely used in the fields of sewage/wastewater treatment,black and odorous water restoration,sponge city construction,and water source protection.Choosing the type of constructed wetland according to local conditions is the first step in the design of constructed wetland,which not only affects the land occupation and related pollutant removal,but also directly affects the project cost,operating cost and ecological landscape effect.This paper summarized the main types of constructed wetlands in recent years,analyzed the selection principles of constructed wetland types and the influence on engineering design.Combined with the engineering design of a water source protection wetland in Chongqing,the idea of comparison and selection of constructed wetland type design schemes was introduced,which could provide some reference for the design of constructed wetland related projects in China.
