摘　　要：重庆市涪陵第二水厂扩建工程(原规模为6×104m3/d,新增规模为4×104m3/d),包括新建取水泵站、净水处理构筑物和输水管道等几部分。针对长江原水浊度较高的特点,采用了两级高效反应沉淀池、均质石英砂滤料气水反冲洗滤池处理工艺。两年多的运行实践表明,该工程不仅达到并优于原设计要求,而且投资省、运行费用低、占地少,为其他类似老水厂的扩建提供了新思路。The expanded engineering of Fuling Second Waterworks in Chongqing City （ the original treatment capacity is 6 × 10^4 m^3/d, and the expanded treatment capacity is 4 × 10^4 m^3/d. ） includes newly built intake pump stations, purification treatment units and water supply pipes, etc. Considering the high turbidity of the Yangtze River water, two-stage high efficient reaction and sedimentation tanks, and sand filter with air-water backwashing are employed. Two years practical operation shows that compared with the original one, the expanded project is better in design requirement, cost effective in investment and operation, and space saving. The project may offer a reference for the expanded engineering of other old waterworks.
