摘要：To remove the organic compounds from epoxy resin wastewater which contains high concentration sodium chloride, a catalytic wet peroxide oxidation (CWPO) process was applied to treat it. The effect of different reaction conditions on total organic carbon (TOC) removal efficiency was evaluated, and the experimental results showed that the optimal H2O2 dosage, Fe2+ dosage, temperature, and pH were 0.735 M, 0.027 M, 90 degrees C and 3.0, respectively. Multiple additive methods of H2O2 and Fe2+ significantly enhanced TOC removal than the one step addition. The TOC value of treated wastewater was lower than its limit for diaphragm electrolytic cell feed, thus it could be recycled to a chloro-alkali process for reusing.
