重污染河流闸坝作用分析及调控策略研究

摘要

The water pollution incident in middle reaches of Huaihe River is frequent. For this reason taking the dams of Shaying River(in Huaihe River watershed)as a research case,this paper established one dimensional hydrodynamic-water quality model for multiple dams based on HD and AD modules in the Mike11 software. Researching on multi-scene simulation in dams of Shaying River,effects of regulation on river water quality were analyzed to correctly understanding of the relationship between dam operation and water quality change. Furthermore regulation strategies of heavily polluted rivers were proposed. The research of this paper could provide technical support for joint regulating of water quantity&quality and mitigating the negative impact on river environment.%针对淮河中游频发的水污染事件，以淮河流域重污染河流沙颍河上的闸坝群为研究对象，分析了闸坝对水环境的影响，提出重污染河流闸坝调控策略。基于MIKE11软件的HD和AD模块，构建了多闸坝河流一维水动力水质模型。通过多场景模拟，分析了沙颍河上的闸坝群调控对河流水质的影响，以便于正确认识闸坝调控和河流水质变化之间的关系，进一步提出重污染河流闸坝的调控策略。
