Oxidation Treatment of Phenol and Formaldehyde Wastewater by Fenton Reagent

The paper described the use of Fenton reagent in the oxidation treatment of phenol and formaldehyde in wastewater.The influences of different dosage ratio of initial concentration Fe2+and H2O2 solution,temperature,pH,to the degradation of phenol and formaldehyde in wastewater were discussed.The results showed that the optimized conditions were dosage ratio of the 100 mg·L-1 Fe2+ solution and 30% H2O2 solution of 8,temperature of 65 ℃,pH of 3.0,the removal rate of phenol and formaldehyde were better.In this environment,the removal rate of phenol and formaldehyde could reach up to 90%.This study provided more information to the treatment process of industrial wastewater.
