摘　　要：制浆废液中的多酚化合物是影响其后续利用和污染环境的主要因素,采用XDA-1、D301、XDA-7树脂分别对造纸废液进行脱酚处理。结果表明:XDA-1脱酚效果较好,在最佳条件下,即流速1.5ml/min,样品中酚类浓度为0.3mg/ml左右,上样pH为2.0时,酚类的脱除率达到97.7%,还原糖损失率为5.8%。采用80%乙醇洗脱柱,88.9%的多酚得到回收。Polyphenol is the major factor of inhibiting the following fermentation and polluted environment in the waste water of ethanol pulping.In this paper,XDA-1,D301 and XDA-7 were used for removing polyphenol.The results show that resin XDA-1 is the best method in phenol removal,the optimal condition are as follows：flow rate 1.5mL/min,sample concentration 0.3 mg/ml,sample pH 2.0,under which phenols removal rate can reach 97.7%,with reductive sugar loss rate at 5.8%.Chromatography column was eluted by alcohol at concentration of 80%,with 88.9% of polyphenol recovered.
