连续处理造纸黑液的研究

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。

A Study of Pulp Black Liquor Continuous Treatment

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 0.11ml/s,radiated power P is 400W,activated carbon catalyst bed height L is 18cm,the black liquor absorbance 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...
