上海大场水厂给水工艺设计及特点

Improved Technological Design of Dachang Waterworks in Shanghai

上海大场水厂是我国第一座以BOT形式建设的自来水厂 ,设计规模为 4 0万m3/d。介绍了水厂的净水工艺流程、水质目标、各净水构筑物及其主要设计参数、设备配置、各种药剂的投加系统和控制方式 ,以及各在线检测仪表等内容 ,并分析了大场水厂的工艺设计和设备配置的一些特点。

This project of waterworks with design capacity of 400 thousand cubic meters per day is the first waterworks constructed on BOT contract in this country. In this paper the main figures of this project including the water purification process, expected quality of output water, water purification facilities with design parameters, equipment allocation, chemical dosage system and their control and online metering instruments are presented in detail. Also the particularities in process design and equipment provision are discussed.
