摘要
针对现阶段桃浦河主干河道日常“大引大排”的引调水模式造成的感观度较差等问题,通过1 D水动力与物质输移模型模拟分析,对桃浦河上游泵闸调度模式进行优化研究。多工况模拟结果表明,旱天时,木渎港泵闸引水流量5 m^(3)/s,引水时长8 h工况下,桃浦河沿程流速达到0.05 m/s,流速适中;全河道引水5.44 d,可达到地表水Ⅳ类标准,水质改善效果好,并能兼顾经济性。研究结果可为桃浦河水环境治理与木渎港泵闸优化调度提供有效数据支撑。
In response to the poor visibility caused by the daily large diversion&discharge water diversion mode in the main channel of the Taopu River at present,an optimization study is conducted on the upstream pump gate scheduling mode of the Taopu River through simulation analysis of 1D hydrodynamic&material transport models.The simulation results of multiple working conditions show that during dry days,the water diversion flow rate of the Mudu Port pump gate is 5 m^(3)/s,and the water diversion duration is 8 hours.Under the working condition,the flow velocity along the Taopu River reaches 0.05 m/s,which is moderate.The entire river channel diverts water for 5.44 days,which can meet the Class IV standard for surface water.The water quality improvement effect is good,and it can also consider economic benefits.The research results can provide effective data support for the environmental treatment of Taopu River and the optimization scheduling of Mudu Port pump gates.
