苏北某给水厂设计(含CAD图)(任务书,开题报告,设计说明书17000字,CAD图7张)
摘要
自来水是通过净化、消毒等一系列工艺后生产出来的符合国家标准的供人们生活、生产使用的水。它主要通过水厂的取水泵站汲取江河湖泊及地下水，地表水。并经过沉淀、消毒、过滤等工艺流程，最后通过配水泵站输送到各个用户。
此次毕设的题目是《苏北某给水厂设计》。首先，根据源水的各项指标，自然条件，水文条件等查阅资料，通过比较当前的自来水处理工艺确定了一套完整的工艺。本次设计采用的工艺流程为：机械搅拌絮凝池—斜管沉淀池—普通快滤池—消毒。工艺成熟，处理效果较好，能满足设计要求。对净水系统、主要构筑物尺寸以及高程做了计算。最后结合计算数据，绘制各单元构筑物的工艺图，平面布置图，高程布置图等相关图纸。

ABSTRACT
Drinking water is water which meets national standards after Series oftreatment process such as purification ,disinfection .etc.It’s used for living and production. First,rivers and lakes Water,groundwater and surface water is absorbed mainly through water pumping station.. After sedimentation, disinfection, filtration and other process, water is transportedn to all users through water pumping statio finally.
The topic of the graduation desighis 《Subei a water-supply plant design》.In the first place,according to the source water indicators, natural conditions, hydrological conditions etc ,consult data access. Determine a set of complete process by comparing the current water treatment process.The process is: Mechanical agitation flocculation tank—tube settler—rapid filter—disinfection。Technology used is mature, the treatment effect is good, it can satisfy design requirements.water purification system, the main structures’s sizes and elevation are calculated. Finally, with the calculated data draw every structuresthe layout, elevation map and other related drawings.
Key words：tapwater；coagulation；filtration；disinfection
