| 摘 要： | 针对中国多闸坝重污染河流的典型代表——淮河中游河网,为提高其流域水环境预警及应急响应能力,依据水文-水动力-水质耦合数学模型DHQM(Hydrology, Hydrodynamics, and Water Quality Model )的理论框架,构建了由淮河干流、沙颍河和涡河3个一维模块和鲁台子、蚌埠闸2个二维模块组成的淮河中游河网水文-水动力-水质耦合数学模型.采用经过验证的模型针对一个虚拟的水污染事故情景,分析了不同调度方案与淮河干流来水组合下污染团下泄对下游水质的影响;并以保障淮河干流蚌埠市饮用水源地的取水水质安全和减轻事故对下游水质的影响程度为目标,优选出分期小流量慢速下泄污染水体为最佳的水量水质联合应急调度方案.

| Abstract: | In order to improve the ability of water environment pre-warning and emergency response on the Huaihe River basin, the Hydrology, Hydrodynamics, and Water Quality Model (DHQM) is developed for the Huaihe Middle River network. The Huaihe DHQM comprises three 1-D parts (Huaihe River stem, Shaying River, and Guohe River) and two 2-D parts (Lutaizi Reach and Bengbuzha Reach). The water quantity and quality series during 2004 and 2008 were used to calibrate and validate the model, respectively. A typical virtual accident scenario was assumed based on the pollution characteristics of the Huaihe River basin. The Huaihe DHQM was applied to analyze the effects of pollution mass on downstream across different combinations of regulation scheme and flow from the Huaihe River stem. After comparing the modeling results of different regulation schemes, the slow release of water from several installments under a low discharge was identified as the optimal emergency scheme that could secure the water quality of Bengbu and minimize the influence of pollution mass on downstream. |
