摘　　要：采用微波辐射处理麦草浆蒸煮黑液,由正交实验来确定其最优工艺条件是:麦草浆蒸煮黑液流速u为0.11mL/s,微波辐射功率P为400W,活性炭催化剂床层高度L为18cm,处理后的黑液吸光度为0.061,木素去除率为n=90.2%。根据极差判断:微波辐射功率对处理效果的影响最大,活性炭催化剂床层高度次之,流速对黑液处理效果影响最小。Microwave irradiation was used to treat wheat and straw black liquor.The best process conditions were determined by orthogonal experiment.They are as follows：the wheat and straw pulp black liquor velocity u is 0.11 mL/s,radiated power P is 400W, activated carbon catalyst bed height L is 18 cm,the black liquor absorbanee after treating is 0.061,the removal of lignin n is 90.2%.Judging by range,the effects on black liquor treatment from strong to weak are microwave radiated power, activated carbon catalyst bed height,and velocity.
