碩士 === 國立雲林科技大學 === 化學工程與材料工程系 === 103 === This study attempts to electrochemical oxidation method persulfate oxidation or peroxymonosulfate oxidation combine with ultrasonic for the degradation of phenol, by changing the electrolysis potential, the reaction temperature, persulfate concentration, pH values and strength of ultrasound to investigate the effect of the degradation of organic pollutants, H2O2 generation rate and possible reaction pathway. Its organic phenol solution concentration of approximately 150 mg / L. The results showed that a combination of chemical oxidation process when peroxymonosulfate oxidation of organic matter removal, electrolysis potential 6 volt, reaction temperature 45 ℃, pH value of 1, potassium peroxomonosulfate dosage under 3 wt% of operating conditions, after reaction 9 hours, the effect of oxidative degradation of organic matter 95%. Substituted phenol in aqueous solution with ultra pure water was measured by a spectrophotometer to generate the amount of hydrogen peroxide, which can be found the amount of hydrogen peroxide generated is consistent with the above results, it can be proved by electrochemical oxidation method persulfate oxidation or peroxymonosulfate oxidation combine with ultrasonic process can remove phenolic wastewater.
