| Abstract: | In this paper, the removal of phenol from simulated wastewater was studied using gas–liquid fluidized bed with the Fenton reagent. The factors that affect the removal rate of phenol were investigated, including the initial concentrations of hydrogen peroxide [H2O2] and [Fe2+], the molar ratio of [Fe2+]/[H2O2], pH value, temperatures, reaction time, and the ventilation volume. It was found that the optimal operating conditions existed as: [H2O2] = 12 mmol/L, [H2O2]/[Fe2+] = 4:1, pH = 4, T = 60 °C, reaction time of 30 min, and a ventilation volume of 0.12 m3/h. Under these conditions, the phenol removal rate of about 96% was obtained. |
