摘要
围绕金泽水库水源特点,在"十一五"和"十二五"成果基础上,针对金泽水源运行水厂存在的耗氧量、三卤甲烷总量超上海地标风险,浑浊度、嗅味物质等偏高,出厂水有抗生素检出的问题,进行金泽原水水厂工艺集成优化关键技术研究。结果表明,通过水厂前后臭氧投加优化、活性炭滤池运行优化以及水厂消毒方式优化,出厂水浑浊度不高于0.15 NTU,2-MIB、土臭素不高于5 ng/L,三卤甲烷总量不高于0.5,磺胺类抗生素去除率不低于60%,出厂水水质稳定达到国家标准和地方标准。
Focusing on characteristics of Jinze Reservoir,and on the basis of research results of"Eleventh Five-Year"and"Twelfth Five-Year",research on key technologies for process integration and optimization of Jinze Water Treatment Plants(WTPs),to solve the problems that CODMnand THM have the risk of exceeding Shanghai local standard,turbidity and odor substances are occasionally detected high,and antibiotics are detected.Results show that through the optimization of ozone dosing,activated carbon filter operation and disinfection method,effluent turbidity is not higher than 0.15 NTU,2-MIB,geosmin is not higher than 5 ng/L,THM is not more than 0.5,removal rate of sulfonamide antibiotics is not less than 60%,and water quality of WTPs is stable and reaches national standard and local standard.
