摘　　要：以纤维素酶、酯酶等组成的复合酶对美废纸浆进行脱墨,得到了美废纸浆脱墨优化的工艺条件为:碎浆浓度12.5%,碎浆时间20min,碎浆温度35～40℃,pH8～9,吨纸复合酶用量200g和吨纸助剂用量800g。在此工艺条件下,#3美废纸浆经脱墨后纸浆白度达到43.5%,纸浆白度高于化学脱墨。The compound enzyme which contains cellulase, esterase used for deinking of the old American newsprint and the optimized technological conditions were obtained： pulping consistency 12.5%, deinking time 20min, pulping temperature 35-40℃, pH8-9, compound enzyme dosage 200g paper, auxiliary agent 800g paper. Under this condition, the brightness of old American newsprint is 43.5% and higher than that of the chemical deinking pulp.
