活性艳橙的脱色处理研究

探讨了分别使用粉煤灰和壳聚糖处理活性艳橙模拟废水的效果。结果表明：用粉煤灰吸附处理的工艺条件为室温下振荡2 h、振荡速度200 r/min、吸附剂用量0.01 g/mL、pH值约为7,此时最大脱色率为88%;用壳聚糖吸附处理的工艺条件为室温下振荡2 h、振荡速度200 r/min、吸附剂用量0.000 3 g/mL、pH值约为7,此时脱色率达97%以上。处理后的废水都达到了我国污水综合排放标准中的一级标准。

Research on Decolorization and Handlization of Reactive Orange

In this work,The raw material are fly ash and chitosan,investigating the effection of fly ash or chitosan by handling simulated wastewater of reactive orange.The result indicated: the optimum conditions of fly ash handling simulaed wastewater of reactive orange is 2 h for the oscillation time,200 r/min for the oscillation speed,0.01 g/mL for the dosage,7 for the pH ambient temperature,at those conditions,the best decolorization is 88 percent;the optimum conditions of chitosan handling simulated wastewater of reactive orange is 2 h for the oscillation time,200 r/min for the oscillation speed,0.000 3 g/mL for the dosage,ambient temperature with 7 for the pH at those conditions,the best decolorization is 97 percent.
