| 摘 要： | 基于浙江省东苕溪干流水文特性,结合流域水质与污染物情况,应用MIKE11模型构建了流域水动力和水质耦合模型。率定河道糙率为0.018–0.022,氨氮降解系数为0.07–0.10/d,总磷降解系数为0.07;验证模型计算值与实际测定值吻合程度较高。模拟上游水污染突发事件发生后污染物到达东苕溪水源地取水口的时间,以此进行水质预警。计算水源地取水口发生水污染事件后不同水期条件和不同污染物的情况下需要的上游自净稀释水量,以保障饮水安全。

| Abstract: | Based on the hydrological characteristics of Dong Tiaoxi main stream in Zhejiang Province,the basin hydrodynamic and water quality coupled model is built by applying the MIKE11,which combined with the river water quality and pollutant.Calibration of roughness is 0.018-0.022,degradation coefficient is 0.07-0.t0/d.The validation of the model calculation value and actual measuring results are satisfactory.The arrival time from upstream to water source intake in Dong Tiaoxi River is simulated,in order to carry out the water quality early warning,when pollution emergencies occurred.When in water source upstream water pollution incidents occurred,self purification dilution water quantity of need for different water conditions and different pollutants in the circumstances has been calculated,to protect the safety of drinking water. |
