Abstract

Effect of pH on ozone oxidation and peroxone AOP(Advanced Oxidation Process) process was analyzed and the optimal 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/$\ell$). When reaction time increased to 90 min(ozone dosage of 201mg/$\ell$), 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/$\ell$). When reaction time increased to 90min(ozone dosage of 201mg/$\ell$), the removal efficiency of color, CODMn, and BOD5 increased slightly by 1~5%.
