摘要

The purpose of this investigation focused on the activity of catalytic oxidation for organic pollutant in soils by activated carbon catalyst. It was found that high decomposition efficiency for organic pollutant oxidation in this system when the pollutant concentration was lower than 250 mg/mL. Over 90% removal efficiency can be obtained in this oxidation system. The factors in the oxidation efficiency were investigated by considering the oxidation efficiency. An 80% removal can be achieved in 30 minutes and almost completely decomposition of organic pollutant was found in 180minutes in this batch catalytic oxidation reactor. The parameters were considered such as: dosage of catalyst, concentration of oxidant, reaction temperature and reaction time in this oxidation system. The significant enhancements on oxidation rate were found by changing the reaction temperature, dosage of oxidant, and dosage of catalyst. The properties of soil influence the oxidation rate of organic pollutant in this system.
