摘　　要：混合办公废纸(MOW)有较高的回收利用价值,但目前传统的碱性脱墨体系对其脱墨能力较弱,脱墨效率低下。故本文利用脂肪酶用于MOW的脱墨,讨论其最优脱墨工艺条件,分析其脱墨效率。研究发现脂肪酶L ipasefrom Cand ida rugosa的脱墨效率为86.0%,成纸白度为80.22%ISO、脂肪酶L ipase from porc ine pancreas的脱墨效率为91.13%,成纸白度为83.08%ISO。Mixed office waste paper （MOW） has a higher value to recycle, but the deinking efficiency of conventional alkali deinking system is relatively low. This paper tries to gain the optimization condition of lipase deinking of MOW. The results show that, the deinking efficiency of lipase from candida rugosa is about 86.0% , and the paper＇s brightness is 80.22% ISO; the deinking efficiency of lipase from procine pancreas is about 91.13 % , and paper＇s brightness is 83.08% ISO.
