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%.
