| Abstract: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 bleaching process for flax pulp. ZEMP bleaching of flax pulp could not only obtain good bleach properties of bleaching pulp, but also the CODCr, BOD5 and chromaticity of bleaching wastewater were lower． |
