摘　　要：以亚麻浆为原料,对其进行ZEMP(臭氧、碱处理、M助剂脱木素、过氧化氢)的漂白研究,探讨了漂白过程洗涤水循环回用对纸浆漂白性能和废水污染负荷的影响,比较了4种不同漂白工艺流程(ZEMP、CED、OZED、OPZP)的漂白结果和废水污染负荷。结果表明,ZEMP为亚麻浆的最佳漂白工艺流程。采用ZEMP漂白工艺对亚麻浆进行漂白,且洗涤水循环回用,不仅可以得到漂白性能良好的纸浆,且漂白后废水的COD_(Cr)、BOD_5和色度均较低。The ZEMP four stage bleaching of flax pulp in low consistency pulp condition was studied. The influence of water circulation on bleaching performance and wastewater pollution load was investigated. The bleaching results and wastewater pollution loads of 4 different bleaching sequences （ZEMP,CED,OZED,OPZP） were compared. The results showed that ZEMP was the best pulp. ZEMP bleaching of flax pulp could not only obtain good bleach properties of bleaching pulp,but also the CODCity of bleaching wastewater were lower.
