In this study, the advanced oxidation processes (AOPs) using Fenton reaction (F-AOPs) was applied in order to remove colour in combined wastewater from pulp and paper industry after treated by a combination of coagulation and activated sludge. The effects of key operating parameters, such as the concentration of iron (II) sulfate, hydrogen peroxide dosage, pH, visible light as well as photocatalyst TiO2 on the decolorization were studied and discussed. Some kinetic rate constants at different conditions have been determined. The results shown that F-AOPs was a suitable technique for removing colour from effluent from pulp and paper industry. At optimum conditions, the colour removal was more than 90% and 100% without with photocatalyst after 40 minutes of reaction, respectively.
