芜湖江南集中供水区应急水源工程设计与运维

Design and operation maintenance of emergency water source project of south of the Yangtze River concentrated water supply area in Wuhu

为解决对长江水源过度依赖问题,芜湖市建设了相应的应急水源工程,应急水源地为漳河,取水规模为17.8万m^3/d。根据工程规划建设条件,对取水口选址、原水管道选线进行了比选论证,介绍了取水头部、自流引水管、取水泵站、原水管道设计方案。针对应急水源工程长期闲置不用的特点,制订了运营维护方案。最后提出一些思考,为其他应急水源工程的设计和运维提供一些参考。

In order to solve the problem of relying on water source from the Yangtze River excessively,the corresponding emergency water source project was built in Wuhu.The emergency water source of this project is the Zhanghe River,and the water intake scale is 178000 m^3/d.According to the project planning and construction conditions,the selection of water intake location and raw water pipeline route were demonstrated,and the design scheme of water intake,artesian diversion pipe,water intake pumping station as well as raw water pipeline were introduced.In view of the long-term idle characteristics of emergency water source project,an operation maintenance plan was made.At last,some thoughts were put forward,which can provide some references for the design and operation maintenance for emergency water source projects.
