摘　　要：山地水厂周边地形起伏大、地质情况特殊等特点决定了其设计的特殊性,恩施市地处鄂西南山区,其新第二水厂规划供水规模22×10^(4)m^(3)/d,属典型山地水厂。介绍了该水厂总体设计、原水取水及水厂主要构筑物工艺设计,并总结了水厂设计和运行特点。通过设置配水井,灵活采用水泵提升或重力自流方式以适应水源变换;因地制宜,采用现场制备次氯酸钠消毒和采用智能加矾装置以方便后期运行管理,在降低劳动强度的同时节约了药耗。同时对项目建设的优化可能进行了探讨,供同类水厂设计参考。The design of waterworks in mountainous area had particularity due to the the large topographic relief and special geological conditions. Enshi City is located in the mountainous area of southwestern Hubei, and the planned water supply scale of its new No.2 Waterworks is 22×10^(4) m^(3)/d, a typical mountain waterworks. The general design of the waterworks, the intake of raw water, and the process design of the main structures of the waterworks were introduced, and the design and operation characteristics were summarized. The mode of pump lifting or gravity gravity flow were adopted to adapt to the change of water source by setting water distribution wells. According to local conditions, sodium hypochlorite disinfection prepared on site and intelligent alum adding device were adopted to facilitate later operation and management, reduce labor intensity and save drug consumption. At the same time, the optimization possibility of project construction was discussed, offering a reference for the design of similar mountain waterworks.
