摘　　要：本实验研究了废纸脱墨浆的FAS漂白工艺及其影响因素,探讨了FAS用量、NaOH用量、温度、时间对纸浆白度的影响,以及FAS漂白(F)和TAED活化H2O2(P)两段漂白工艺条件。结果表明,影响废纸脱墨浆漂白效果的顺序为:FAS用量>时间>温度>NaOH用量;废纸脱墨浆FAS漂白的最佳工艺条件为:FAS用量0.6%,NaOH用量0.3%,温度70℃,时间30min。PF两段漂白优于FP两段漂白。FAS bleaching technology and affecting factors as well as FAS（F） TAED activated H2O2（P） two stages bleaching of deinked pulp were studied in this paper.The results showed that the sequence of FAS bleaching affecting factors was FAS dosage,reaction time,temperature and NaOH dosage.The optimum bleaching conditions were FAS 0.6%,NaOH 0.3%,reaction time 30min,temperature 70℃.PF two-stage bleaching was better than FP two-stage bleaching.
