构筑生态湿地改善桐乡市西部水源水质探讨

Discussion on improvement of water source quality in western Tongxiang City by constructing the ecological wetland

分析了嘉兴市石臼漾湿地、贯泾港湿地、海宁市长水塘湿地、泰山港湿地等水源生态湿地和盐城市区饮用水源盐龙湖工程的工艺流程和净化效果。结合现状环境条件,认为建设桐乡市西部饮用水源生态湿地切实可行,且可参照嘉兴地区的水源生态湿地模式。实施桐乡市西部饮用水源生态湿地工程能够满足规划取水规模的目标,较显著地改善原水水质,达到集中式饮用水源水质的标准要求。建议在生态湿地设计中,充分考虑现状,对可能出现的问题做好防范,保证湿地的稳定运行,确保水质达标,保障供水安全。

As the samples,the technological process and purification effect of water source ecological wetland were analyzed,including Shijiuyang wetland and Guanjinggang wetland in Jiaxing City,Changshuitang wetland and Taishangang wetland in Haining City,and Yanlonghu water source protection project in Yancheng City. According to the present environment conditions,it was considered that it was feasible to construct ecological wetland for drinking water source in western Tongxiang City,referring to the ecological wetland model of the Jiaxing area. The implementation of the ecological wetland project for drinking water source in western Tongxiang could meet the goal of planned water intake,significantly improve quality of the raw water and meet the standard requirements of the centralized drinking water source. It was suggested that full consideration of the present situation and prevention of possible issues should be taken in the design of ecological wetland,so as to ensure the stable operation of the wetland,guarantee the water quality and water supply safety.
