高铁酸盐去除印染废水色度的实验研究

Research on Wiping Off the Chroma of Dye Waste by Ferrate

用高铁酸盐对活性染料废水、分散染料废水和生产印染废水进行了脱色实验,结果表明:高铁酸盐能有效地去除印染废水的色度,在pH=6~8,投量为40mg/L时,色度的去除率达90%以上。

The ferrate was used to decolorize reactive dyes waste,disperse dyes waste and production dyes waste.The result shows that ferrate can effectively remove the chromaticity of dyes waste.When PH is 6-8 and the throwing amount is 40mg/L,the removing is up to 90%.
