组合式进水池在郭公庄水厂中的应用

Application of combined inlet tank in Guogongzhuang Water Treatment Plant

郭公庄水厂一期工程供水能力为50万m3/d,针对其多水源特征,采用预臭氧—机械澄清—主臭氧—活性炭吸附—超滤膜—紫外线消毒的处理工艺。为了实现水力条件好、水头损失小、便于维护管理、节省占地面积等要求,设计将进水溢流井、预臭氧接触池和机械混合井组合成一个构筑物,介绍了其组合方案及其工艺设计参数。

The capacity of water supply in Guogongzhuang Water Treatment Plant is 500 000m3/d. Based on multi-water resources, the process of pre-ozone-mechanical clarification-main ozone-activated carbon adsorption-ultrafiltration-UV disinfection was selected as the treatment process.In order to achieve better water hydraulic conditions, lower head loss, easier maintenance, savingarea, the combination of inlet-overflow well, pre-ozone contact tank and mechanical mixing wellwas brought forward. The layout and design process parameters were introduced.
