摘要
PURPOSE: a kind of method and apparatus enter waste water by injecting oxygen-containing gas for eliminating photocatalysis oxidation reaction that coloration contains reactive azo dyes waste water from eminence concentration salt effectively to realize the removal process based on coloration. ;CONSTITUTION: photo-catalyst and oxygen-containing gas introduce the salt containing reactive azo dyes waste water and high concentration. Ultraviolet light irradiation is aoxidized to photochemical catalyst decomposition reaction azo dyes based on photo-catalyst. The flow velocity for the introducing oxygen-containing gas for including in the oxygenated gasoline of 10 volume % oxygen is 10 to 40 volume % per minute. The pH value of waste water is adjusted to lower than initial pH value waste water. The air throttle mixed up limits opening value and is in 4 and 10.Between range;The 2012 of copyright KIPO submissions
