Study on the Wet Oxidation of a Kind of Pharmaceutical Wastewater with Hydrogen Peroxide

Abstract The wet oxidation of a kind of pharmaceutical wastewater with hydrogen peroxide, i.e. H2O2, was studied in this paper. In this study, H2O2 was utilized as an oxidant. The effects of reaction conditions were investigated, including theinitial concentration of the pharmaceutical, the reaction temperature and reaction time, and the additional amount of H2O2. The highest Chemical Oxygen Demand (COD) removal rate among the performed experiments in this study, approximately 89.6%, was obtainedat 240 °C for 60 min with the additional amount of H2O2solution 2 mL. These results illustrated that the wet oxidation process using hydrogen peroxide as an oxidant was effectively for the degradation ofthis kind of pharmaceutical wastewater.
