摘要

Wastewater from textile processing plant can be highly colored and difficult to decolorize. Combined UV and hydrogen peroxide oxidation has been applied successfully to the treatment of various water pollutants. In the present study, advanced oxidation treatment, UV/H_2O_3 was applied to decolorization of three azo dyes, Acid Orange 7, Acid Orange 8 and Methyl Orange. The study described herein is an investigation of treatability of these dyes in the continuous circulation photoreactor. The UV radiation was carried out with a 15 W low-pressure mercury lamp. Rate of color removal have been studied by measure of the absorbency at characteristic wavelength. We have observed that the decolorization reaction is pseudo-first order with respect to the dye concentration. The effect of H_2O_2 dosage, dye initial concentration and pH on decolorization kinetic in the continuous circulation photoreactor was investigated.
