Advanced treatment of high-viscosity petrochemical wastewater was studied with the oxidation method by Fenton’s reagent as oxidant and the oxidation mechanism and kinetics were analyzed.According to the results from a series of single-factor experiments
it was observed that the control parameters in the oxidation process had different effects on COD removal rate.Through comparing those experimental results
a desirable COD removal rate of 62.00% was obtained at initial mass ratio R(=H2O2/COD)=1.52
molar ratio M(=H2O2/Fe2+)=10∶1
initial pH 3.0 and temperature of 25℃.A kinetic study was carried out by using a modified pseudo-first-order model with the reaction constant of k computed by multiple regression analysis.The experiments performed at different temperatures allowed the calculation of the Arrhenius equation parameters and the global activation energy Ea (25.5 kJ·mol-1)for the pseudo-first-order reaction.
