摘要
本工程为邳州市运河镇某自来水厂给水工程设计,水质为生活饮用水水源水质分为二级标准。
该工程设计水量目标,预计该自来水厂总规模为40000m3/d。
整个工程包括三大部分: 取水工程、净水工程。
取水工程设计主要以地表取水位置的选择,通过查阅资料,知道净水工艺流程的要求以及在选厂址时的基本原则,然后设计出一些方案,并做出比较,最后选出一个合适、可行性的方案根据水质、水量、地区条件、施工条件和一些水厂运行情况、确定处理工艺流程并,定处理方案,拟定各处理构筑物的设计流量。,
净水工程主要设计内容为净水厂的设计计算,包括水处理流程的确定、处理水构筑物的设计计算及水厂平面和高程布置图。本设计主要计算的构筑物有药剂投配设备设计、静态混合器的、斜管沉淀池、无阀滤池、无阀滤池等设计计算。选定各构筑物的形式和数目,根据确定的净水厂位置,初步进行水厂的平面布置和高程布置,在此基础上确定构筑物的形状,有关尺寸和安装位置等。
进行各构筑物的设计计算,定出各构筑物和各主要构件的尺寸,设计时要考虑到构筑物及构件施工的可能性,根据各构筑物的确定尺寸,确定各构筑物在平面位置上的确切位置,并最后完成平面布置,确定各构筑物间联接管道的位置、长度、材料及附属设施,并最后定出水厂的高程布置,绘制部分构筑物(滤池)及有关细部的计算草图

Abstract
This engineering is a waterworks pizhou canal town water engineering design, water quality for domestic and drinking water sources water is divided into secondary standard.
The engineering design water target, expected the waterworks total dimensions for 40000m3 / d.
The whole project includes three parts: water engineering, water purification.
Water engineering design mainly based on the ground water location choice, access to information, know purification process requirements, as well as in selected site when the basic principle, then designed some solutions and make parison, in order to choose an appropriate, the feasible scheme according to the water quality and quantity, regional conditions, the construction condition and some waterworks operation situation and determine treatment process and, settle scheme, develop the treatment structures design flow. ,
Water purification main design content for the design and calculation of the 2004, including water treatment processes defining, processing water structures design calculation and waterworks plane and elevation layout. This design putational structures have elixir shots match equipment design and static mixer, inclined pipe traps, no valve filters, no valve filter, such as design calculation. Selec
