摘  要

本设计为福州市XX区给水工程工艺设计，工程设计规模为80000m3/d。

整个工程包括三大部分： 净水工程、供水工程。

净水工程的设计主要包括净水厂的设计计算。

供水工程的设计内容包括供水泵站的设计。 

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：  

原水—→静态混合器—→机械絮凝池—→斜管沉淀池—→普通快滤池—→消毒—→清水池—→二级泵站—→城市管网

关键词：净水工程；静态混合器；机械絮凝池；斜管沉淀池；普通快滤池

Abstract

The design is water supply project for donghai city with the total volume of 90 thousand cubic meters.

The whole project consists of three parts which is Water purification project，water giving project .

Water purification project contains of water proportioning plant design.

The water giving project consists of the design of pump station. 

  The 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 to compare to both technologically and economically. And the programme is preferred. The whole process is as follows: raw water→Static mixer→Machinery flocculation pond→settling tank→high speed filter cell→disinfection(add chlorine) →second pump station→ municipal pipe network. 

Key words: water purification project; Static mixer; Machinery flocculation pond; settling tank; high speed filter cell
