ABSTRACT

efficiency for both processes was obtained at pH 7.5. In case of ozone oxidation process, the efficiencies of color,COD_(Mn) and BOD_5 removal were measured to 93%, 70% and 89% at a reaction time of 50 min(ozone dosage of 111.67mg/ℓ). When reaction time increased to 90 min(ozone dosage of 201mg/ℓ), the efficiencies of color, COD_(Mn), and BOD_5 removal were increased by 3~5 %, indicating that the increment of removal efficiency was insignificant considering longer reaction time. Similarly, the ozone/H_2O_2 ratio was optimized to 0.5 for peroxone AOP process. Removal efficiencies of color, COD_(Mn) and BOD_5 were measured 95%, 81% and 94% at a reaction time of 50 min(ozone dosage of 111.67mg/ℓ). When reaction time increased to 90min(ozone dosage of 201mg/ℓ), the removal efficiency of color, COD_(Mn), and BOD_5 increased slightly by 1~5%.
