摘要:
位于长江口的青草沙原水系统承担着上海市中心城区60%以上的原水供应任务。受2022年8月以来长江流域持续干旱和台风的接连影响，青草沙水库遭受咸潮入侵，取水受限。在此背景下，黄浦江上游原水应急支援青草沙原水系统，松浦大桥泵站在原水切换支援青草沙系统过程中，在最大设计供水流量下通过水泵调速提高供水效率。总结了应急供水期间的设备保障和运行管理措施，黄浦江的水质变化以及通过投加粉末活性炭优化供水水质的做法。
Abstract:
The Qingcaosha raw water system, located in the Yangtze River estuary, is responsible for more than 60% of raw water supply in downtown Shanghai. However, the Qingcaosha reservoir has been invaded by saline tides and limited water intake, due to continuous drought and successive impacts of typhoons in the Yangtze River basin since August 2022. In response, the upstream Huangpu River has provided emergency support to the Qingcaosha raw water system. Songpu Bridge pumping station enhances water supply efficiency by adjusting pump speeds under the maximum design water supply flow rate when raw water is switched to support the Qingcaosha system. The equipment guarantee and operation management measures, the water quality changes of Huangpu River, and the practice of optimizing water quality by adding powdered activated carbon during the emergency water supply period are summarized.
