摘要
重污染河流上的闸坝过量蓄水是导致污染团集中下泄造成水污染事件的主要诱因之一。针对这一问题,本文提出和定义了防污限制水位的概念,并以兴利和防污为目标,构建了重污染河流闸坝防污限制水位模型,以研究预防因污染团集中下泄造成水污染事件的闸坝防污限制水位,规范重污染河流闸坝的蓄水量。将该方法应用到淮河流域沙颍河的多个闸坝,计算结果表明,该模型能够有效地求解重污染河流的闸坝防污限制水位,具有一定的实用性。这对重污染河流开展闸坝防污调度研究提供重要的技术支撑。
The excess water stored by sluices and dams on heavily polluted rivers is a main causation of sudden pollution incident caused by the concentrated discharge of pollution regiment. Focusing on this problem, a concept of limited water level for the pol- lution control is proposed and defined herein. Furthermore, a model of limited water level for pollution control of sluices and dams on heavily polluted rivers is built by taking benefit promotion and pollution control as the target, so as to study the limited water level for preventing the sudden pollution incident caused by the concentrated discharge of pollution regiment and standardize the storage volumes of sluices and dams on heavily polluted rivers. As a case study, this method is applied to several sluices and dams on Shayinghe River; from which the results show that the limited water level for pollution control can be effectively obtained by the model, and then it has certain practicability. The study mentioned herein provides an important technological support for the research made on the operation of pollution control of sluice and dam on heavily polluted river.
