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, FeSO 4 2.5mmol/L, H 2 O 2 3.4mmol/L, and reaction time at 20 minutes, the removal efficiencies of COD and color are more than 85% and 90%, respectively.
