Study on Treatment of Wastewater from Papermaking Using Fenton Oxidation

Abstract:

The performance of biochemical treatment effluent from paper making wastewater treated by Fenton process was evaluated. The experiment result shows that the importance of influencing factors for Fenton oxidation treatment was H₂O₂ concentrations > pH > FeSO₄ concentrations > reaction time. With the optimal conditions of reaction, that is pH3 (initial pH5), FeSO₄ 3.6 mmol/L, H₂O₂ 3.4 mmol/L, and reaction time 60 min, the removals of COD and color for papermaking wastewater reached over 85% and 90%, respectively. The result also showed that in the process of Fenton method in the treatment of papermaking wastewater, for removing COD, the function by oxidation account for 15.5%, and the function of flocculation accounted for 69.8%.
