人工湿地技术在住宅小区雨水回用工程中的应用

Application of Constructed Wetland Technology in a Residential District Rainwater Utilization Project

为实现源头雨水的径流总量控制、径流峰值控制、径流污染控制,南京某住宅小区雨水回用工程采用垂直潜流人工湿地将住宅屋面和道路雨水转化为产品水,用于绿化浇灌和道路浇洒。采用人工湿地处理处理雨水,运行处理成本约0.5~1元/t,具有良好的节水效能和环境生态效益,可为类似工程设计提供借鉴和参考。

To control the volume of runoff, the peak value of runoff and the pollution of runoff, the vertical subsurface flow constructed wetland technology is used to treat roof and road rainwater in a residential district rainwater utilization project in Nanjing. The treatment rainwater is used to irrigate green land, flush road. The cost of rainwater treatment is about 0.5~1 Yuan/t by using the technology. Constructed wetland technology has good water-saving and environmental ecological efficiency, which can provide references for the similar projects.
