| 摘 要： | 为探索一种高效简便的糖蜜酒精废液脱色方法,本实验采用交联阳离子淀粉对糖蜜酒精废液进行脱色处理,考察了交联阳离子淀粉用量,废液初始pH值,搅拌吸附时间及吸附温度4个因素对糖蜜酒精废液脱色率的影响,通过正交实验,确定了最佳工艺条件.实验结果表明:在室温下,当交联阳离子淀粉投加量4.5 g/L,废液初始pH 9.0,吸附时间7 min时,脱色率可达85.7%,脱色效果优异,操作简便.

| Abstract: | In order to find an efficiency method,this paper studied the decolorization performance of cross-linking cationic starch to molasses alcohol wastewater.Four factors such as the cross-linking cationic starch dosage,initial wastewater pH,the adsorption time and temperature were studied.Through orthogonal technical treatment processing,the optimal processing condition is obtained.The results show that at room temperature,when the cross-linking cationic starch is 4.5 g/L,the initial pH is 9.0 and the adsorption time is 7 min,the decolorization rate is up to 85.7%. |
