摘　　要：采用济宁电厂二级除尘灰处理分散黄模拟染料废水,对处理结果进行了分析和研究,并进一步探讨了其脱色机理.结果表明,在强酸或强碱性条件下,当粉煤灰的投加量为20.0 g/L,搅拌反应80 min时,脱色率可达到90%以上;脱色的机理为粉煤灰表面的活性点位以及未燃尽的残余碳的吸附作用.The treatment of simulative dyeing wastewater by fly ash from Jining power plant is studied. Results indicate that the removal rate is above 90% under the condition of strong acid or alkali for 80 min at the dosage of 20.0 g per L wastewater. The mechanism of decolouration is the co-adsorption of active spot and the unburned carbon.
