北京市亦庄水厂一期工程设计介绍

Introduction to the design of the first phase project of Beijing Yizhuang Water Treatment Plant

北京市亦庄水厂工程是南水北调配套工程建设中的重要节点,担负着向北京东南部地区供水的重要任务。亦庄水厂工程净配水厂远景规模为150万m^3/d,一期工程设计规模为50万m^3/d,主要采用南水北调中线作为水源,针对原水条件,水厂采用预臭氧、机械混合、机械搅拌、砂滤池、主臭氧、活性炭池的长流程工艺。介绍了一期工程的工艺流程和主要构筑物的工艺参数及设计特点,并对该厂设计特点及设计理念进行了介绍和初步探讨。

The Yizhuang Water Treatment Plant in Beijing is an important node in the construction of supporting projects for the South-to-North Water Transfer Project and is responsible for the important task of supplying water to the southeastern part of Beijing.The prospect of the Yizhuang waterworks project water distribution plant is 1.5 million m^3/d.The design scale of the first phase project is 500 000 m^3/d.The South-North Water Transfer middle line is mainly used as the water source.For the raw water conditions,the water plant adopts pretreatment-conventional treatment-depth treatment.This paper introduces the process flow of the first phase of the project and the process parameters and design features of the main structures.
