某水厂改扩建工程集约化设计方案

Integrated Design Proposal of Reconstruction and Extension Project for a WTP

为应对供水格局变化和水量增长,通过系统方案论证,提出拆除水厂内已停运的一期工程,新建15万m^3/d常规处理和30万m^3/d排泥水处理设施。结合一期工程拆除后的地形条件进行平面布置,降低工程投资。本期充分考虑远期深度处理系统,提前建设预臭氧接触池,滤池设置双层渠道和切换阀门,减少远期建设对水厂生产的影响。水厂建(构)筑物采用组合、叠合设计,节约用地,可供类似改扩建工程设计参考。

To cope with the changes in water supply pattern and increased demand of water quantity,a design project proposal is brought up and evaluated systematically.The proposal intends to dismantle the existing constructions and facilities of decommissioning first-phase project,and to reconstruct 150000 m^3/d conventional drinking water treatment and 300000 m^3/d sludge treatment facilities.The layout design is based on terrain conditions after dismantling the first-phase facilities,which may decrease overall cost of the project.The proposal of this phase also takes future phase into consideration as well.The ozone-contact tank,filter tank with double-layer water channels and switching valves will be constructed in advance,which may diminish the future upgradation impacts on daily water productivity.Combined and superimposed design concepts are applied to this project,which will save the land requirements.This project can provide references for similar project.
