摘要
以南通城区文峰水系水环境治理工程为案例,介绍了从整体水系考虑的水体流动性提升策略,并创新采用了拓扑导流墙技术实现水系内部断头河的原位连通,最终达到"濠河—文峰水系—八窑河"的有序流动。监测数据表明,自2019年4月工程投入使用以来,河道水质已稳定提升至Ⅲ类水质标准,河道流速从原先的滞留状态达到现在的6 cm/s以上,市民与河道的互动从零恢复到了正常水平。
Based on the project of water environment treatment in Wenfeng river system of Nantong, this paper introduced an systematic treatment strategy to increase the river flow rate, where topological diversion walls were innovatively designed to realize the in-situconnectionsof dead-ended rivers. The continuous water flow of "Haohe River-Wenfeng River-Bayao River" has been realized. After the implementation of the project, the monitoring data indicate that the water qualities of Wenfeng River Systemhave metthe Class III water quality standards, and the flow velocities of the rivershave increased to 6 cm/s and above. The interaction between citizens and the rivers has returned to normal level.
