%X The mechanisms of affecting factors in treating formaldehyde-containing organic wastewater by electro-Fenton reactor which had granular carbon as the filled electrode were investigated. The optimal operating conditions determined by orthogonal experiments and individual factor experiments were as following: 90 min, 25 V, 30 degrees C-40 degrees C, insulating carbon content 40%, Fe2+ concentration 300 mg/L at pH < 3.5. Formaldehyde degradation mechanisms were proposed after analyzing the oxidation products with UV absorbance spectrum. Experiment of treating the actual wastewater using this method were also performed. The removal rates of formaldehyde and CODCr were about 90%, 30%, respectively. In addition, the operating cost was 42.3% less than that of treatment by Fenton method.
