摘 要
本设计的主要任务是XX省XX市某区给水工程初步设计。设计的主要内容包括:给水处理工艺选择、净水厂设计、二级泵房设计。
本设计的设计规模是10.5万m3/d,以地表水为水源。采用的给水处理工艺为:原水→管式静态混合器→折板絮凝池→斜管沉淀池→普通快滤池→清水池→二级泵房→城市管网。选用硫酸铝为混凝剂,液氯为消毒剂。水厂出水水质要求达到《生活饮用水卫生规范》(GB5749-2006) 。
水厂位于淄博市的东北方,地面标高为34m,总占地面积12.5公顷,绿化面积约占25%,附属面积约占总面积的15%,力争创建一个清新怡人的现代化水厂。

Abstract
The main task of this design is in XX City in XX Province, the preliminary design of the county water supply project. The key elements of design: design to determine water supply systems, water treatment plant design, the secondary pumping station design.
This design is the size of the recent design of 105,000m3 / d, for the water to river. Used for water supply system: the source of the water →primary water pumping station→assigned wells→Folded plate flocculator→Inclined pipe sedimentation- rapid filter→clean-water reservoir→secondary pumping station→city pipeline. Selection of coagulant aluminum sulfate, liquid chlorine as disinfectant. Water plant to meet water quality requirements, "Drinking Water Health Standards" (GB5749-2006).
Water Treatment Plant is located in northeast of the city, the ground elevation is 255.3m, the total area of 12.5 hectares, accounting for about 25% green area, sub area of about 15% of the total area and strive to create a modern and pleasant fresh water plant.
Key words:Water-supply engineering design;Folded plate flocculator;Inclined
