- Abstract
There is high concentration of organic matter in the antibiotic wastewater, and its COD is up to 10000–5000 mg/l, which is one of the more obscure typical waste water. In this paper, wet oxidation (WO) is applied to treat antibiotic wastewater in a reactor under the following conditions: reaction temperature – 210 to 270°C; H2O2 dosage – 100 to 700 mg/l, and reaction time – 1 to 7 min. The effect of the given experimental conditions on total organic carbon (TOC) removal was investigated. The results indicated that temperature is a key factor in reducing TOC. As the reaction time and H2O2 dosage increase, TOC removal rises. The optimum TOC removal reached 87.3% under the experimental conditions. The preliminary study of mechanism on antibiotic wastewater by WO is carried out. The results indicate that antibiotic wastewater by WO can be explained by free radical mechanism.
