METHOD AND APPARATUS FOR ENHANCED PHOTOCATALYTIC OXIDATIVE DECOLORIZATION OF WASTEWATER CONTAINING REACTIVE ANTHRAQUINONE DYE

摘要

PURPOSE: a kind of method and apparatus induce photocatalysis oxidation reaction for eliminating efficiency with raising of the coloration from reactive anthraquinone dyes waste water based on photochemical catalytic oxidation by adjusting salinity and the pH value of above-mentioned elimination waste water. ;CONSTITUTION: photo-catalyst and salt inject reactive anthraquinone dyes waste water. Ultraviolet light irradiation to photochemical catalyst degrading activity anthraquinone dye. The coloration of waste water is eliminated. Salinity waste water is maintained between 25 and 100 g/L. Or mixtures thereof one of salt, NaCl, Na_2SO_4, KNO_3, CuSO_4, NH_4Cl, CH_3COONa. Photochemical catalyst is titanium dioxide. One kind for eliminate coloration from reactive anthraquinone dyes waste water include photocatalytic oxidation reactor, ultraviolet radiator, salt feeding unit, alkali feeding unit. ;The 2012 of copyright KIPO submissions
