X1 市给水工程初步设计 摘 要X1 市位于湘南省西部，是一个古老而美丽的城镇，位于溆水中游，近期规划人口 12 万人，远期发展到 20 万，市区已建了一座 3 万 m3/d 的水厂。随着经济的发展、用水量的增长，现有供水能力已满足不了正常的生产和生活所需。根据城市总体规划，拟在溆水上游建设一新水厂。新水厂建成后，与老厂联合向管网供水，形成统一供水的局面。本设计的主要内容包括：取水构筑物设计；净水厂设计；输配水管网设计；工程概预算四部分。根据城市管网供水的需要，计算得新水厂近期供水规模为 5 万 m3/d，远期为 10 万 m3/d。为保证出水水质，所以新水厂处理工艺采用常规处理＋深度处理（臭氧－生物活性炭），增加深度处理后，能使出厂水水质明显提高。工程建设总投资为 9373.65 万元,单位制水成本为 0.85 元/。关键词：取水构筑物，净水厂，常规处理工艺，V 型滤池，配水管网，概预算AbstractAs an ancient and beautiful city, X1 city is located in the west of Hunan. On the middle reaches of Xu River, the city has a planning population of 120,000 which, in long term, will be expanded to 200,000. There has already been a 30,000 m3/d waterworks in the downtown area. With the development of economy and the increasing demand of water, its current water supplying capacity can not meet the requirement of regular production and people’s daily life. According to the city’s comprehensive planning, it is proposed that a new waterworks should be constructed on the upper reaches of Xu River. When it is completed, the new waterworks will be joined by the old one to supply water to the pipe network, thus making a state of unified water supply.This design mainly covers four parts which are: the water intake works, the purification plant, the tubeweb system of carrying and providing water, and the budgetary estimation of the design.According to the demand of the pipe network, it is calculated that the short-term water supply scale of the...
