摘要
本设计为富县县城给水工程设计,工程设计规模为60000m3/d。整个工程包括三大部分: 净水工程、供水工程和输配水工程。净水工程的设计主要包括配水厂的设计计算和净水厂的设计计算。供水工程的设计内容包括供水型式的确定及供水泵站的设计。
输配水工程主要指管网的定线和管网的水力平衡计算。净水厂的设计包括净水厂的位置选择、水处理工艺流程的确定、处理构筑物的设计计算以及水厂的平面和高程布置。
通过技术经济比较,确定净水厂的工艺流程选用方案:
混凝剂
水源 一级泵房配水井
消毒剂
机械搅拌澄清池 V型滤池 清水池 吸水井
二级泵房配水管网用户

Design of Water-supply and Water-treatment system of fuxian
Abstract
The design is water supply project for fuxian city with the total volume of 60 thousand cubic whole project consists of three parts which is Water purification project,water giving project and water arrangement and clarification purification project contains of water treatment plant design and water proportioning plant water giving project consists of the form of water giving and the design of pump station. The water allocation and clarification projects contains of the arrangement of pipelines, the determination of pipe caliber as well as pump design of water purification project contains of the selection of water treatment factory address, water treatment process of identification, handling the design of structures and the calculation of the plane and elevation water plant layout.
According pare to both technologically and economically. And the programme is preferred.
