| 摘 要： | 本论文主要是以传统CEH漂白为参考基准,对蔗渣浆的无元素氯漂白(ECF)流程DQP和全无氯漂白(TCF)流程OQP进行比较,包括漂后纸浆的性质(粘度、返黄值以及裂断长、撕裂指数、耐破指数)和漂白废水的污染负荷(CODcr,BODs,SS和AOX),结果发现OQP和DQP漂后纸浆都具有较高的强度性能、较好的白度稳定性,而且废水具有较低的污染负荷.

| Abstract: | In this paper,bagasse pulp ECF bleaching sequence DQP and TCF bleaching sequence OQP were compared based on the traditional CEH bleaching which included the properties (viscosity,postcolor number, breaking length, tear index and burst index) of the bleached pulps and the pollution loads of the effluents. It was found that both OQP and DQP bleached pulps had higher strength properties and better brightness stability, and the effluents had lower pollution load. |
