摘　　要：肥东县自来水厂一期规模为10×10^4m^3/d,扩建工程包括10×10^4m^3/d供水设施和20×10^4m^3/d排泥水处理设施。因项目建设用地紧张,故采用最节约用地的水处理技术,优化总图布置,精细化利用土地。水源为水库水,水质优良,扩建工程采用"水平管沉淀池+V型滤池"工艺;紧凑型布置的脱水机房占地面积小,空间利用率高,管理方便。为应对水源水质变化以及出水标准的提高,设计预留深度处理系统,建设用地同步保留。工程总投资为6314.35万元(无征地费用),单位水量总成本为0.319元/m^3。项目实际运行中经历了冬天的低温低浊期、春夏的雨季高浊和高温高藻期,进水指标波动对水厂运行的影响可控,出水水质稳定达标。The original treatment capacity of Feidong Waterworks was 10×10^4 m^3/d.The expansion project included 10×10^4 m^3/d water supply facilities and 20×10^4 m^3/d sludge water treatment facilities.Because of the shortage of construction land for the project,the water treatment technology of the most economical land was adopted to optimize the layout of the general plan and make fine use of the land.Source water came from reservoir water,and the water quality was excellent.The expansion project technology route was combined of"horizontal tube sedimentation tank+V-type filter".The compact sludge dewatering room occupies small area,had high space utilization rate and was convenient for management.In order to cope with the change of water quality and the improvement of effluent standard,the advanced treatment system was designed and the construction land was kept synchronously.The total investment of the project was 63.1435 million yuan(none land costs),the total cost of water per unit was 0.319 yuan/m^3.The actual operation of the project has experienced a period of low temperature and low turbidity in winter,high turbidity in rainy season,and high temperature and algae in spring and summer.The influence of actual influent index changes on the operation of the waterworks could be controlled,and the effluent quality reached the standard.
