【摘要】 针对北京密云水库水的水质特征,分别进行了实验室烧杯和现场中试研究。实验结果表明,预臭氧化能使原水中较大粒径颗粒数目减少,并能显著降低原水中不饱和有机物的含量;高效聚合氯化铝在颗粒物及有机物的去除上明显优于传统的聚合氯化铝和硫酸铝;预臭氧化与常规处理的联合工艺对浑浊度、有机物和大肠菌群有很高的去除率。更多还原

【Abstract】 According to the characteristics of raw water of Miyun reservoir,jartest and pilot scale experiments were employed respectively for water treatment.The results showed that the particles with large size decreased when preozonation was applied,meanwhile,the organic matters with unsaturated chemical bonds decreased obviously.Moreover,the treatment efficiency of HPAC was better than which of traditional PAC or aluminum sulfate.The results also showed that turbidity,organic matters and coliform could be treated efficiently by preozonation combined with traditional technologies.更多还原
