摘　　要：为改善饮用水水质,保证供水安全,宁波市江东水厂采用热法PVDF超滤膜技术对该水厂二期、三期工程的饮用水常规处理工艺进行了升级改造。该升级改造工程将原有虹吸滤池改造为浸没式超滤膜池,最大限度地降低工程造价,同时能保证出厂水水质满足《生活饮用水卫生标准》(GB 5749—2006)。改造完成后,该厂供水量达到20×104m3/d,为大型水厂的膜法水处理建设提供了宝贵的经验和借鉴。To improve the drinking water quality and ensure water supply safety, Ningbo Jiangdong Waterworks upgraded its conventional drinking water treatment processes in adopting thermal PVDF uhrafiltration membrane technology. This upgrading Phase Ⅱ and Ⅲ projects by project transformed the original siphon filter into submerged uhrafihration membrane filter, to minimize the construction cost and en-sure the finished water quality to meet the requirements of the Standards for Drinking Water Quality （ GB 5749 - 2006）. After transformation, the water supply quantity of this waterworks reached 20×10^4m^3/d, providing experience and reference for the application of ultrafihration membrane technology in large waterworks.
