山东省济南市天桥区新建给水处理工程设计-毕业设计说明书.doc

摘要 水资源是人类赖以生存的重要，也是我国持续发展的保障如何保证饮水的清洁是给水工程的重要问题在给水排水工程的不断发展中，如何合理利用水处理技术，给社会带来健康符合标准的水源已经成为水处理的重中之重，也是我们给水人员不可推卸的责任。 本设计题目为：设计规模为：100m3/d,含自用水量），处理后的水质严格按照《生活饮用水卫生标准》（GB5749-）执行首先根据城市地形图确定水厂位置，按地形确定城市网形式本设计采用，管网平差确定城市供水最不利点根据水源水质确定净水工艺流程原水→→取水泵站→管式静态混合器→→斜管沉淀池→V型滤池→清水池→二级泵房→城市管网本设计中所选用的方案具有运行经验丰富、处理效果好、施工简单、配套设备少占地面积小、管理方便等特点。 关键词给水工程净水厂V型滤池  Abstract Water resource is an important material for human and it is also the basic guarantee for the sustainable development of our country. With the development of modern society，the demand for water supply and drainage facilities in cities and towns is increasing. How to ensure the clean water is an important problem in water supply project. In the development of water supply and drainage engineering，how to use the water treatment technology，to social health in line with the standards of water has becoming more and more important and water supply of our staff unshirkable responsibility. This design topic is： New Design of Water Supply Project in Jilin Changyi District，the main purpose is to protect the water supply in Changyi District of Jilin city water quantity and quality. Water purification plant design scale is set to：130624.6m3/d（including water content），the water quality after treatment in strict accordance with the Drinking Water Health Standards（GB5749-2006）implementation. First of all，the position of water city terrain is determined by the drawings and site selection principle.Then，the form of urban pipe network is determined by the terrain,this design uses the unified water supply，in ordering to ensure the water supply safe use of pipe network,and the most disadvantage of urban water supply is determined by the adjustment of pipe network.Secondly，according to the water quality condition of water source， the water purification process is determined by comparing with the technology.This design uses aluminum sulfate as coagulant and liquid chlorine as disinfectant.The selection of the design of the program has a w
