| 摘 要： | 探讨了木聚糖酶处理对NaOH-AQ麦草浆HD漂白的影响.结果表明,AU-PE89木聚糖酶处理可以有效改善NaOH-AQ麦草浆HD漂白效果,在本实验条件下,当酶用量为7.5 U/g时,漂白效果最理想,白度增值为3.3%ISO;同时,AU-PE89木聚糖酶处理还可以降低HD漂白废液的CODCr,减少漂白污染.通过扫描电镜观察发现,经木聚糖酶处理后纸浆的纤维结构变得更疏松,纤维更加润胀柔软.

| Abstract: | The effects of xylanase treatment on HD bleaching of NaOH-AQ wheat straw pulp was investigated.It was found that xylanase AU-PE89 treatment could improve HD bleaching efficiency of the NaOH-AQ wheat straw pulp.The bleaching effect was optimal and brightness gain of 3.3%ISO was obtained when the dosage of xylanase was 7.5U/g.Xylanase AU-PE89 treatment could also decrease the COD_(Cr) of HD bleaching effluent,thus reduce bleaching pollution.Based on the analysis of Scanning Electron Microscope(SEM),it was found that the xylanase treatment could improve the fibers swelling and softening,and make the fiber structure looser than the control sample. |
