摘　　要：以粉煤灰为吸附剂,对某厂染料废水进行了吸附研究。实验结果表明,当废水pH为6时,粉煤灰对染料废水有较高的脱色率和COD去除率,适宜的粉煤灰投加量为每100 mL废水投加20 g,搅拌只能加快吸附速率,缩短吸附平衡时间,但是不会改善粉煤灰的吸附能力。Adsorption of dying wastewater on fly ash was studied, and the result indicated that fly ash had high adsorption capacity for dying pollutants. The optimum fly ash load was 20 g per 100 ml of dying wastewater at pH 6. Stirring could shorten the time of adsorption, but had little influence on the adsorption capacity.

关 键 词：粉煤灰 染料废水 吸附 COD
