摘要:This paper deals with treating heavy oil wastewater via supercritical water oxidation (SCWO) with Nano-ZnO. The effects of H2O2 dosage, reaction time, reaction pressure, temperature and concentration of Nano-ZnO dosage on COD removal were studied. The results indicated that the process was effective under the experimental conditions. The best COD removal reached 98.26%. Nano-ZnO exhibits good catalytic activity.
