摘　　要：采用D-101大孔树脂和活性炭两步吸附法对糖蜜酒精废液进行脱色处理,实验表明,该法有明显的脱色效果,脱色率达98.3%,脱色后CODCr去除率>90%,色素可有效回收利用。A two-step sorption procedure has been developed for the decoloration of sugar molasses alcohol wastewater. D - 101 resin and activated carbon are employed as sorbents in the procedure and satisfaction results have been achieved. The decoloration ratio is up to 98.3%, and the removal rate of CODCr reaches 90%. The pigments can be reclaimed and the sorbents can be reused effectively.
