摘　　要：选用活性炭对低浓度铬黑T实验室模拟废液进行脱色处理,通过活性炭用量、活性炭浓度,搅拌时间、pH值等变量,进行脱色率的试验。通过设计正交实验选出的最佳脱色条件为:活性炭用量1000mg/L,搅拌时间100min,铬黑T质量浓度15mg/L,pH为2。试验证明在此条件下进行脱色,脱色率都达到90%以上。The Eriochrome Black T Wastewater was decolorized by activated carbon under experimental conditions. The decolorization ratio was investigated in terms of dosage of activated carbon, stirring time and pH. The optimal process parameters obtained from orthogonal experiment are as follows：the dosage of activated carbon is 1 000 mg/L, stirring time 100 min, eriochrome black T 15 mg/L and pH 2.The results showed that decolorization ratio was above 90% under optimal conditions.
