摘 要本设计是对安徽省某城市给水厂进行工艺设计，该水厂的设计日供水量为6.5 万吨，水源为水库水，水源水质符合《地表水环境质量标准》Ⅲ 类水体标准。水源水质符合集中式生活饮用水地表水源地水质要求，是可选择的城市供水水源。设计的主要任务是根据水量和水质完成该水厂的给水处理及构筑物的初步设计，水厂平剖面图和主要构筑物平剖面图的图纸绘制。由于水源没有受到污染无需预处理及深度处理，则该水厂的处理工艺流程为常规处理。即：原水→混凝→沉淀→过滤→消毒→用户。设计中对各个构筑物进行了详细的计算，并绘制图纸 11 张。主要构筑物为：折板絮凝池、平流沉淀池、普通快滤池和清水池。关键词：常规水处理工艺；平面布置；高程布置AbstractThis design was about a city of Anhui province water supply plant process design. The flow is 65000m3/d, of water for reservoir water, water quality in line with" environmental quality standards for surface water" class III water standard. Water quality conforms to the centralized drinking water source of surface water quality requirements, may be the choice of city water supply. The design of the main tasks is to complete the water quantity and quality of water treatment and the structures of the preliminary design, in horizontal section and main structures flat profile drawing. Since water pollution has not been without pretreatment and depth of processing, then the water plant for the treatment process conventional treatment. which was: raw water→ flocculation & coagulation→ filtration→ disinfection→ consumer. Design of the various structures detailed calculation,and produce drawing chapter 11.The main structures consist of spacer flocculating pond, horizontal sedimentation tank, conventional rapid filter&clean water pond.
