在经过校核验证后的某流域排水系统旱季水质水量模型的基础上,利用雨天关键节点水量水质同步监测数据对雨天水质模型进行校核,建立了较为精确的流域排水系统雨天水质模型。利用构建完成的水质模型对研究片区的污染物排放总量进行了核算,并对河道水质状况进行了情景预测;最后,利用模型对现有排水设施的运行策略进行了优化探讨。 Based on the dry-season water quality model of a drainage system in a watershed after verification and verification, the rainy day water quality model was checked by using the simultaneous monitoring data of the water quality of the key nodes at the rainy season, and a more precise rainwater quality model of the drainage system was established. The constructed water quality model was used to calculate the total discharge of pollutants in the study area and the situation of the water quality of the river was forecasted. Finally, the operation strategy of the existing drainage facilities was optimized by using the model.
