摘　　要：针对淮河干流污染团事件应急处置的需求,对污染团事件的水质水量联合调度措施进行研究。构建淮河干流中游段的水动力水质模型,分析加大蚌埠闸流量、加大引江济淮流量、两者同时加大、背景调度(无引江济淮工程)和常规调度(有引江济淮工程,但不加大流量)5种调度方式对淮河干流污染团的应急处置效果。结果表明:从污染团离开研究区域时间、峰值长度、峰值质量浓度等角度看,不同调度方式对污染团的处置效果有所不同;加大蚌埠闸流量、加大引江济淮流量和两者同时加大对污染团的处置效果均比背景调度和常规调度更优。研究结果可为淮河干流突发水污染事件应急处置提供参考。The water transfer project from the upper reaches of the lower reaches of the Yangtze River to the middle reaches of the Huaihe River is a large-scale inter-basin water transfer project,which is mainly based on urban and rural water supply and the development of Jianghuai shipping,combined with irrigation water replenishment and improvement of Chaohu and Huaihe River water ecological environment.The main stream of the Huaihe River is a storage area for the water transfer project from the Yangtze River to the Huaihe River,and there are many tributaries around it.Once a sudden water pollution incident occurs and improperly handled,it will seriously affect the water supply safety of the main stream and the water transfer section.The joint operation of water quality and quantity is a key measure to deal with sudden water pollution incidents and an important part of improving the water ecology of rivers and lakes.A HEC-RAS one-dimensional hydrodynamic-water quality model of the middle reaches of the Huaihe River was constructed for the event of the Huaihe River pollution group caused by the discharge of sewage from the Shaying River.The emergency response effects of five scheduling methods on the Huaihe River pollution group were analyzed,including increasing the flow of Bengbu sluice,increasing the flow of water transfer from the Yangtze River to the Huaihe River,increasing both at the same time,background scheduling(no water transfer from the Yangtze River to the Huaihe River)and conventional scheduling(water transfer from the Yangtze River to the Huaihe River,but not increasing the flow).The results show that:for the background scheduling,the peak concentration of the pollution mass is the highest,the exceeding time is the longest,the peak length of the pollution mass is the shortest,and the latest to leave Bengbu gate;for conventional scheduling,the peak concentration of the pollution group is high,and the exceeding time is long.For the optimization of Bengbu gate scheduling,the peak concentration of pollution gro
