摘要
市政泵站雨天放江污染已成为影响上海市中心城区河道水质持续稳定改善的主要因素之一。为推进河道水质持续稳定改善提供技术支撑,同时为泵闸联合调度精细化管理提供精准化决策,以上海市某重点河道及其服务范围内市政泵站为研究对象,建立区域排水系统泵闸联调一体化模型,根据区域防汛安全保障和河道水环境保护的需求,基于多种降雨工况下,模拟河流监测断面水动力和水质结果,分析市政泵站放江对受纳水体的水质影响情况,提出市政泵站和河道泵闸在各种降雨类型中联动运行优化调度的建议,为上海市中心城区其他河道水环境质量持续改善提供引领示范,同时为国内其他城市内涝和河道泵闸优化调控提供参考和借鉴。
The pollution from municipal pumping station in rainy days has become one of the main factors affecting the continuous and stable improvement of river water quality in the central urban area of Shanghai.In order to provide technical support for the continuous and stable improvement of river water quality,and provide precise decision-making for the fine management of joint pump and sluice joint operation,the integrated model of dynamic coupling of regional drainage pipe network and river network was established with the key river channels in Shanghai and the municipal pump stations within their service scope as the research object.According to requirements of regional flood control security and river water environment protection,the model simulates the hydrodynamic and water quality results of river monitoring section under various rainfall conditions.Based on the forecast results,this study puts forward suggestions for the linkage operation and optimal scheduling of municipal pumping stations and river pump gates in various rainfall types,providing a leading demonstration for the continuous improvement of water environment quality of other river channels in downtown Shanghai.At the same time,it provides reference for the optimization control of waterlogging and river pump sluice in other cities in China.
