废纸浆因含有大量的细小组分和阴离子杂质，极大地影响了纸机网部的滤水性能和成纸质量。笔者应用漆酶处理废新闻纸脱墨浆，研究其去除胶黏物的效果。结果表明：漆酶/木聚糖酶体系（LXS）处理废纸脱墨浆，能有效去除浆料中胶黏物，尤其是漆酶/木聚糖酶体系处理后碱抽提（LXS+E）去除效果更佳。在酶用量为15 μmol/(min·g)时，LXS和LXS+E处理后与原浆相比，浆中胶黏物分别降低了51.91 %和68.43 %，减轻了后续工序除胶黏物的负荷，改善了浆料滤水性。当漆酶用量为15 μmol/(min·g)时，LXS和LXS+E处理浆与原浆相比，打浆度分别降低了15.22 %和28.26 %。此外通过这两种方法处理还能提高浆料的强度，而浆料得率却稍有下降。

The composition of waste newspaper is very complex and contains a mass of fine components and anionic trashes.This greatly influences the drainability of paper machine wire end and paper quality. The laccase/xylanase system (LXS) treatment of deinked waste newspaper pulp for removing stickies was investigated in this paper. The results indicated that:the laccase treatment of the deinked waste newspaper pulp could effectively remove the stickies in the pulp especially after alkaline extraction(LXS+E).As compared with original pulp, the stickies in pulp after LXS and LXS+E treatment at enzyme dosage 15 μmol/(min·g) decreased by 51.91 % and 68.43 % respectively. The load of removing stickies in the following processes was reduced and the pulp drainability was improved. As compared with original pulp， the beating degree of pulp after LXS treatment and LXS+E treatment at enzyme dosage 15 μmol/(min·g) decreased by 15.22 % and 28.26 % respectively. The strength of pulp with the two enzymatic treatment was improved, but the yield of pulp slightly decreased.
