To treat certain wastewater that has alcohol and phenol, we performed the ozone electrolysis by using the titanium electrode. In this experiment, we examined decomposition voltage of organics, time for electrolysis, and removal efficiency of organics. In addition we compared the ozone oxidation electrolysis. The followings are results; 1. When it comes to the alcohol treatment in wastewater, ozone electrolysis showed higher removal efficiency than ozone oxidation or electrolysis. 2. After comparing the decomposition rate of methylalcohol, ethylalcohol, and prophylalcohol in ozone electrolysis, we knew the fact that increasing carbon number made the decomposition rate slow. 3. According to the treatment of alcohol by ozone electrolysis, decomposition voltage was 50V, time for electrolysis was three hours, and treatment acidity was neutral (pH 6.5 - 8.1). 4. Ozone electrolysis was effective to the phenol treatment. When we treated phenol by using ozone electrolysis for three hours, TOC treatment efficiency was 95%. However, ozone oxidation just showed 45% treatment efficiency.
