Abstract
In this paper, the synergetic action of UV-Fenton catalytic oxidation and nano-TiO2 photocatalytic to treat Azocarmine G dye wastewater was researched. The results show that the best conditions for the treatment of 250mL Azocarmine G dye wastewater are: the dosage of 30% H2O2 is 1mL; the dosage of 0.1mol/L FeSO4•7H2O is 3mL; the dosage of nano- TiO2 is 1g; pH is 4; illumination distance is 21cm. In this case the decolorization rate of dye wastewater will reach 98% and COD removal rate will reach 80%. The best molar ratio of H2O2 and Fe2+ and light intensity of the reaction are also discussed.
