Abstract:

The hydrolytic acidification-Fenton oxidation process has been used for treating refractory-degraded refinery wastewater. A feasible starting-up method for the hydrolysis acidification system is investigated. The reaction conditions and treatment effect of this method for treating refractory-degraded refinery wastewater are determined. The results show that the oxidizability of refractory-degraded refinery wastewater can significantly be improved. This method for treating refractory-degraded refinery wastewater is characterized by simple operation, reliable effect, and good feasibility. Its wastewater COD removing rate reaches 98.5%.

Key words: hydrolytic acidification, Fenton oxidation, refinery wastewater
