Article Preview

Fenton oxidation was applied to treat harbor oil-contained wastewater after coagulation-sedimentation process. Orthogonal test and single-factor experiment showed that the effectiveness of the operating conditions on Fenton process and its performance was in the order of pH>H2O2 dosage>H2O2 /Fe2+ (molar ratio)> reaction time (t)>reaction temperature (T), pH had the greatest effect, in comparison, reaction temperature had the minimal effect. The optimum parameters of Fenton oxidation process were pH of 2.5-4.5, dosage of H2O2 of 4-6ml/L, H2O2/Fe2+ of 20, t of 60-90min, and T of 40°C. Under these reaction conditions, COD concentration was decreased from 317.5mg/L to 132.3mg/L, with the removal efficiency of 58.3%.
