摘　　要：通过对废报纸脱墨浆纤维素酶H_2O_2漂前预处理对漂白结果的影响进行了研究,找出了最佳的酶预处理工艺条件。通过酶预处理的H_2O_2漂白浆比未预处理的H_2O_2漂白浆白度提高约8.8％ISO。所抄浆片白度不但满足产品质量要求,而且其他各项指标也完全达到新闻纸国家A级标准。The effects of cellulase treating on deinked ONP before hydrogen peroxide bleaching were studied. The available technical parameters are found. The brightness of bleached DIP is increased about 8. 8% ISO. The high-quality newsprint can be manufactured.
