南湖水库水源地保护人工湿地系统工程设计

Design of Constructed Wetland System for Water Source Protection of Nanhu Reservoir

面源污染逐渐成为我国地表水体的主要污染源,采取工程措施对其进行控制,有利于保护湖库水质及防止富营养化。随着人工湿地技术的兴起,将其运用于面源污染控制与湖库生态修复的研究和应用日益受到关注。结合重庆市南湖水库水源地保护工程的设计,介绍了人工湿地的水质与水量确定、工艺流程及主要构筑物的设计参数和特点,并对其运行费用和环境效益进行了分析,以期为类似水源地保护工程设计提供参考。

Non-point source pollution is an emerging major source for surface water in China. It is significant for reservoir water quality protection and eutrophication prevention to take engineering meas- ures for controlling non-point source pollution. It is a growing concern that constructed wetlands are ap- plied in non-point source pollution control and ecological restoration of lakes and reservoirs. Combined with the design of the water source protection project of Nanhu Reservoir in Chongqing, an engineering example was introduced, including the determination of water quantity and quality, process flow, design parameters and characteristics of main structures. The operating cost and environmental benefit were ana- lyzed. The purpose is to provide technical reference for the design of similar water source protection pro- jects.
