Ozone has been applied in combination with various processes for the tertiary treatment of municipal wastewater. However, in Korea, the ozone process is mainly employed for the reuse of tertiary treated wastewater, and an enhanced advanced oxidation process (AOP) is needed to realize the large-scale reuse of treated wastewater. In this study, various AOPs employing ozone (only ozone process, O3+H2O2, O3+UV, O3+GAC) were used to analyze the TOC, CODcr, and color treatment efficiencies of municipal wastewater and evaluate its applicability of wastewater reuse. The O3+H2O2 process showed the highest TOC removal efficiency of 62.0%, while the O3+GAC and only ozone processes exhibited the TOC removal efficiencies of 58.9% and 59.3%, respectively. The TOC removal pattern of the O3+UV process was similar to that of the O3+H2O2 process. The TOC removal efficiency of the O3+UV process, 61.0%, was slightly lower than that of the O3+H2O2 process. The CODcr removal efficiencies of the O3+UV and O3+H2O2 processes were 75.8% and 77.0%, respectively. However, the TOC and CODcr removal efficiencies were different within the error range, so there was no significant difference in the processing efficiencies of the methods investigated. The color removal efficiencies of the O3+UV (57.8%) and O3+H2O2 (57.4%) processes were 57.8%, 57.4%. respectively and it showed similar pattern. KCI Citation Count: 0
