| 摘 要： | 以太湖为研究对象,采用Delft3D模型建立了太湖湖区的二维水动力模型,利用2007年太湖污水团事件有关数据进行了验证计算.在SE向3 m·s-1风况下,运用此模型,对太湖湖区不同的调水方案进行了模拟,对比分析了各方案对贡湖取水口处污染物扩散的影响.结果表明:在SE向3m.s-1风况下,望虞河枢纽进水流量越大,对污染物的应急去除效果越好,而增加太浦闸出水流量的效果甚微;贡湖水厂新取水口相比旧取水口,在地理位置、补给水源等方面占优.

| Abstract: | Based on Delft3D model, a two-dimensional hydrodynamic model was established and validated against data of polluted water cluster in 2007 for Taihu Lake. Then hydrodynamic diffusion numerical experiments were performed to compare and analyze the diffusion of polluted water cluster under SE 3 m·s-1 wind condition with different water diversion measures. The simulated results show that the larger drawing flow from Wangyu River, the better effect on pollution diluted near Gonghu Waterworks in northern Taihu Lake, however larger draining flow to Taipu River has little influence there.As for geographic location and recharged water source, new water intake of Gonghu Waterworks is better than the old one. |
