摘要:
本设计的主要任务是内蒙古包头市磴口水厂给水工程设计。设计的主要内容包括:设计规模的确定、给水系统选择、给水方案比较、取水工程设计、净水厂设计和二级泵房设计。
设计书由设计资料、设计说明书和设计计算书三部分组成。
本设计的设计规模是6.5万m3/d,以黄河干流为水源。采用的给水系统为:源水→斗槽(一泵房)→管式静态混合器→机械絮凝池 + 往复式隔板絮凝池→平流式沉淀池→V型滤池→清水池→二泵→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(2001)。
水厂位于包头市郊,城市的东南方,地面标高为1058m,总占地面积4.70公顷,绿化面积约占25%,附属面积约占总面积的15%,内设标准化篮球场和排球场,力争创建一个清新怡人的现代化水厂。http://www.16sheji8.cn/

Abstract:
The main task of my design is for the water supply engineering of dengkou water plant in the city of Baotou,Nengmenggu province. The design mainly includes: the calculation for the volume of the required daily water supply;the choice of the water supply system;the comparison for the process of water supply;the design of water source engineering;the design of the water plant and the secondary pumping station.The design file consists of three parts which are design data,explanation file and calculation file.http://www.16sheji8.cn/
The volume of the required daily water supply of my design is 65000 m3/d .Huanghe River is the source of the water supply. The system of the water supply which is adopted in my design is following:water source → bucket basin(first pumping station) →mixer→machinery flocculating tank+ baffleplate flocculating tank→advection sediment basin→v filter→clear-water reservoir→secondary pumping station→water network. Al2 (SO4) 2 is used as coagulant while Cl2 is used as disinfectant. The quality of processing water must satisfy the norm of domestic drinking water(2001).
The water plant is located in the southeastern suburb of the city of Baotou whose elevation is 1058m.The plant covers 47000m2,which includes 25% green area and 15% accessory area.Besides,standardized basketball and volleyball grounds are set up in order to build a beautiful and harmonious water plant.

1.1 概况
1.1.1 地形概况:
内蒙古包头市位于中国北方,黄河以北。城市现有青山水厂、昆山水厂两座,分别位于城市的东北和西部,而磴口水厂位于城郊,城市的东南方。
磴口水厂可设置在黄河边上,位于城市东南方的城郊,远离居民区,附近有糖厂、铝厂、砖瓦厂,所在位置地面标高约为1004米,地形为北高南低,不平坦。磴口水厂也可设置在城市东南方向,靠近城市的边缘,地面标高约为1050米。可进行方案比较确定。
