In this paper, the treatment of phenol-containing wastewater is studied by using UV/H2O2 system in a bench scale. The influence factors including concentration of H2O2 and phenol, pH, and some metal ions are investigated. The addition of H2O2 was favorable to the removal of phenol, however, the excess of H2O2 does not significantly affect the removal efficiency. It has shown that changes in reaction rates are rather insignificant over a wide pH range from 3 to 8. The co-existence of metal ions has significant influence upon the photocatalytic reaction rates, Fe2+ increases the reaction rates, but Co2O3 and Zn2+ given negative results. The mechanism of the reaction process is also discussed with chromatograms of phenol and its intermediate products.
