Atrazine oxidation in drinking water by ozone and hydrogen peroxide

摘要

The increase of pesticide concentrations in groundwater leads to the necessity of a low cost and effective treatment in order to comply with the maximum contaminant leve. The advanced oxidation processes, which are based on free radicals as the oxidation species, could be a solution with high effectiveness. Herefore experimental studies were carried out on the oxidation of atrazine by O_3 and H_2O_2. Thests were performed to determine the effects of ozone dosage, hydrogen peroxide to ozone dosage ratio, point for injection, injection procedure of H_2O_2 and finally the concentration of bicarbonate.
