摘　　要：采用天然硅藻土处理酸性大红染料废水。在静态条件下,研究了硅藻土用量、振荡时间、溶液的pH和温度对酸性大红染料废水脱色效果的影响。结果表明,在硅藻土用量60 g/L,振荡时间60 min,pH 3,温度20℃条件下,硅藻土对酸性大红染料废水的脱色率最高,达66%。The diatomite was used for the treatment of dyeing wastewater.The influences of the dosage of diatomite,temperature,pH and time on the adsorption of color at static condition were studied.The results showed that the color removal rate was the highest when the diatomite amount was 60 g / L;the value of pH was 3;the time was 60 minutes;and the temperature was 20 ℃.The discoloring rate could be up to 66% under the given optimal conditions.
