城市水厂清水池改扩建工程实施及调试经验总结

Experience of Clean Water Reservoir Renovation and Expansion in an Urban Waterworks

杭州市结合水厂深度处理改造已同步实施多个清水池改扩建工程,包括新建清水池、消毒、大口径管道埋设、大口径管道割接等。通过增加清水池有效容积,使水厂运行调节能力增加,高峰供水压力降低,城市供水安全得到保障。分别介绍九溪水厂、苗圃泵站、祥符水厂的清水池改扩建工程实例,通过难点案例分析,从工程前期、实施、调试三个方面进行了经验总结。

Combined with the advanced treatment reconstruction of waterworks in Hangzhou, several clean water reservoirs have been reconstructed and expanded simultaneously, including new clean water reservoir, clean water reservoir disinfection, burial of large diameter water pipe, large diameter water pipe cut over and so on. The water supply regulation capacity has been improved and the pressure of peak water supply was reduced by increasing the effective volume of the clean water reservoir, thus the safety of the city water supply was ensured. The reconstruction and expansion projects of Jiuxi waterworks, Miaopu pump station and Xiangfu waterworks were introduced. Through the analysis of key cases, the experience was summarized from three aspects of the early stage, implementation and commissioning of the project.
