Abstract
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.
