摘要
介绍了湿地生态系统,以及其概念、类型、分布、功能和构建,分析了我国城市污水回用的方式及存在的问题,阐述了人工湿地生态系统的机理及在污水回用中具有的高效率、低投资、低运转费、低维持技术、处理量灵活、低能耗、处理效果好等优点,说明人工湿地生态系统在城市污水回用中是可行的。
The concept, types, distribution, functions and construction of wetland ecosystem are introduced, and the methods and existing problems of urban sewage recycling in China are analyzed. The mechanism of artificial wetlands and merits of sewage recycling, such as high efficiency, low investment, low operation fees, low maintenance technology, flexible disposal amount, low energy consumption and good treatment effect, etc. are elaborated. It shows that urban sewage recycling technology of artificial wetlands is feasible.
