Research on Yellow River Water Purification Using the Combined Process Containing Hydrogen Peroxide Catalyzed Ozone- Activated Carbon-Sand Filtration Treatment

摘要

By changing the hydrogen peroxide and ozone dosage, the best dosage of hydrogen peroxide to catalyzed ozone- activated carbon-sand filtration process in purify Yellow River Water was found. When the same amount of hydrogen peroxide is filled into the three-level Ozone oxidation column, the combined process's effect is best. The removal rates of TOC, UV_(254), COD_(Mn), Turbidity are 27.72%, 58.66%, 43.30% and 84.90%, the organic content is reduced in a large extent and the finished water quality is improved.
