Combined preozonation and enhanced conventional treatment for raw water of Miyun reservoir
密云水源水的预臭氧化及强化常规处理研究

According to the characteristics of raw water of Miyun reservoir,jar-test 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.
