恩德炉煤灰处理印染废水中的有色染料研究

摘要

Ende furnace coal ash was pretreated in different types of acid, and monomer of dye decolorization tests were carried out. The effect of acid amount,stirring time,Ende furnace coal ash amount and temperature on decolorization rate was investigated. The results indicated that nitric acid had good decolorization effect,and the optimum conditions for treating 100 mL printing and dyeing wastewater were as follows :0. 5 g Ende furnace coal ash , normal atmospheric temperature , stirring time 40 min.%用不同种类酸对恩德炉煤灰进行预处理,并用于对染料单体进行脱色,探讨了加酸量、搅拌时间、加恩德炉煤灰量和温度对脱色率的影响.结果表明,硝酸处理的脱色效果较好,处理100 mL印染废水最适宜条件为:0.5 g恩德炉煤灰在室温下搅拌40 min.
