基于人工湿地的水环境治理和优化技术在太湖流域的应用

水质优化技术在太湖流域水污染治理中起到了重要的作用。介绍了几类常用的基于人工湿地的水质优化技术,包括农村生活污水治理技术、城镇生活污水厂水质优化技术、河道治理技术及雨水治理技术。阐述了人工湿地在太湖流域水系统优化中的应用,包括阳澄湖莲花岛生态湿地对农村生活污水的治理和常熟新材料产业园生态湿地对工业尾水的治理,2个项目水处理效果良好,达到了相应的水质要求。探讨了基于人工湿地的水质优化技术在太湖流域水环境治理和优化的前景,该技术可在海绵城市建设、城镇污水处理厂提标、黑臭河道整治等领域推广和应用。

Application of Constructed-wetland Based Water Treatment and Optimization Technologies in Taihu Lake Basin

Water quality improvement technology plays an important role in Taihu Lake basin water pollution treatment. In this paper, several water quality improvement technology based on Constructed Wetlands (CWs) are introduced, including rural domestic wastewater treatment, water quality optimization for urban domestic wastewater treatment plant, waterway treatment and rainwater treatment. The application of CWs in water quality improvement in Taihu Lake basin were presented, including treatment of rural domestic wastewater with CWs at Lotus Island in Yangcheng Lake and treatment of industrial wastewater with CWs at Changshu Advance Material Industrial Park (AMIP). By these two projects, the treatment has resulted in improvement of water quality which meets corresponding standards. The prospect of applying the CW based water quality improvement technology in Taihu Lake basin was also discussed. This technology can be promoted and applied in construction of Sponge City, upgrading urban wastewater treatment plant and treatment of polluted waterways.
