为研究生态调水对清潩河水质变化的影响并评估生态调水效果,建立适合清潩河的水动力水质模型。以1 m3/s、2 m3/s、3 m3/s不同工况模拟清潩河水动力水质变化规律并分析排污口附近流场和浓度场变化。在分别采取未截污和截污措施,调水流量为3 m3/s时,各断面COD浓度和N H3‐N浓度分别达到V类和Ⅳ类水质标准;生态调水对排污口附近水质改善效果显著;未考虑截污情况下一旦停止调水,污水排入将直接威胁到清潩河水质。通过研究,论证本文理论与方法的可行性和有效性,对该地区的水污染控制与水资源调控方略和可持续发展战略具有现实的指导意义和应用前景。
為研究生態調水對清潩河水質變化的影響併評估生態調水效果,建立適閤清潩河的水動力水質模型。以1 m3/s、2 m3/s、3 m3/s不同工況模擬清潩河水動力水質變化規律併分析排汙口附近流場和濃度場變化。在分彆採取未截汙和截汙措施,調水流量為3 m3/s時,各斷麵COD濃度和N H3‐N濃度分彆達到V類和Ⅳ類水質標準;生態調水對排汙口附近水質改善效果顯著;未攷慮截汙情況下一旦停止調水,汙水排入將直接威脅到清潩河水質。通過研究,論證本文理論與方法的可行性和有效性,對該地區的水汙染控製與水資源調控方略和可持續髮展戰略具有現實的指導意義和應用前景。

In order to study the influences of ecological water diversion upon the water quality change of the Qingyi River and to evaluate the effect of ecological water diversion .Hydrodynamic water quality changing laws of Qingyi River under different working conditions are simulated with 1m3/s ,2m3/s and 3m3/s respectively and the impact on ecological water diversion to the flow and concentration field near the sewage outlet is analyzed .With the adaptation of non‐intercepting and intercepting pollution measures ,the COD and NH3‐N concentrations at each section reach grade V and grade IV when water diversion flow is 3 m3/s ;Ecological water diversion has had an apparent effect upon water quality improvement near the sewage discharge outlet ;Without con‐sidering the intercepting pollution conditions in stopping water diversion ,sewage drainage will di‐rectly threats the water quality in Qingyi River .The feasibility and effectiveness of the theory and method in this paper through studies and tests are of the realistic guiding significance and ap‐plication future for water pollution control and the planning of water resources regulation and control as well as sustainable development strategy in the region .
