Research on treatment of the micro-polluted reservoir water with ozone oxidation

Bench and pilot scale pre-oxidation treatment runs were performed on the raw water samples from micro-polluted reservoir. Bench experimental results showed that the particles with large size decreased when ozone pre-oxidation was applied, meanwhile, the organic matters with unsaturated chemical bonds decreased obviously. Pilot experimental results showed that turbidity, UV254, CODMn and total coliform could be treated efficiently by ozone pre-oxidation combined with traditional technologies, but the effectiveness of DOC removal is not obvious.
