Wastewater Treatment of Pulp and Papermaking Industry by Heterogeneous Fenton Fluid-Bed Reactor

Abstract:

The effluent from biochemical treatment of pulp and paper making wastewater treated by heterogeneous Fenton fluid-bed reactor was evaluated. The results showed that in the condition of COD 350mg/L, and the optimum conditions of pH at 3, FeSO₄ 2.5mmol/L, H₂O₂ 3.4mmol/L, and reaction time at 20 minutes, the removal efficiencies of COD and color are more than 85% and 90%, respectively. The best drug dosing ratio of heterogeneous Fenton fluid-bed reactor has positive relations with COD of raw water, and the mole ratio of COD, FeSO₄, and H₂O₂ is 6.4:0.74:1.
