摘　　要：对新疆博湖苇业公司的碱法苇浆常规CEH三段漂白工艺进行了改进,并分别采用过氧化氢强化漂白工艺流程(CEpH)和过氧化氢补充漂白工艺流程(CEHP),结果纸浆白度明显提高,较常规CEH三段漂分别提高9.65%(ISO)和10.15%(ISO),而CEpH粘度较高,漂程较短。考虑到成本问题,推荐采用CEpH漂白流程及相应的优化漂白条件。To improve the bleaching technology, the CEH three stages process used for KP reed pulp is investigated. The process of H_2O_2 strengthening bleaching(CEpH)and H_2O_2 renewing bleaching(CEHP)are experimented, respectively. It reveals that the pulp brightness is improved by 9.65%ISO and 10.15%ISO, respectively, in comparison with the conventional CEH method. But,(CEpH)is superior in viscosity and shorter in technologic process. Considering the production cost, CEHP　method is recommended with pertinent optimal technology condition.
