摘　　要：研究了麦草化学浆DEP漂白过程中纤维素、半纤维素、木素和苯醇抽出物的降解溶出规律,建立了化学组分溶出量与漂白废水中污染物发生量的相关关系。结果表明,麦草浆化学组分溶出规律:D段木素溶出最多,而E段和P段则是纤维素溶出最多。化学组分的降解物对漂白废水CODCr、BOD5发生量的影响次序为纤维素、木素、半纤维素、苯醇抽出物,AOX与木素溶出量具有较好的相关关系。The degradation of cellulose,lignin,hemicellulose as well as benzene-ethanol extractives was studied during DEP bleaching for wheat straw chemical pulp.The correlative equations between the degradation amount of chemical components and the load of pollutants were established.The results indicated that,the highest degradation amount was lignin in the D stage,but the highest degradation amount was cellulose in the E or P stage.The effect order of degradation of the chemical components to CODCr、BOD5 in the bleaching effluent was cellulose,lignin,hemi-cellulose,benzene-ethanol extractives.The relevance between degradation amount of lignin and AOX was good.
