摘要
为进一步研究通过太浦河调水改善下游水源地水质的调度方式,综合分析了黄浦江上游水文水质历年同步调查数据和太浦河大流量原型试验资料,建立了黄浦江水系水量水质数学模型。选用平水年和枯水年两种年型,以及太浦闸泵联合调度控制的4种不同下泄流量,研究不同年型和下泄流量组合对黄浦江上游水源地水质的影响关系。计算结果表明,在太浦闸流量相对较大的情况下,黄浦江上游水源地水量明显增加,约5～6 d水质明显改善;但当大流量停止且恢复到常规流量时,约2～3 d水质即就恢复到原状。
In order to optimize the water division mode from Taihu River to its downstream, which is designed for improving the quality of water source, the historical investigation data of hydrology and water quality in the upstream of Huangpu River and data of large - discharge prototype experiment of Taipu River are analyzed comprehensively, and the mathematical model of discharge and water quality for water system of Huangpu River is established. In the light of normal year, dry year and 4 different dischar- ges from Taipu Sluice, the influence on water quality of upstream water sources area of Huangfu River are analyzed. The results show that under larger discharge of Taipu Sluice, the water amount in upstream source area of Huangpu River increases and its water quality improves after 5 to 6 days; however, when the discharge returns to normal, the water quality returns to its original state after 2 to 3 days.
