| 摘 要： | 纸浆传统低浓含氯漂白方法(如CEH)存在对环境污染、水耗和能耗大、不可能适应大产能的要求等问题,需要用中浓氧脱木素、中浓二氧化氯漂白、中浓过氧化氢漂白及它们的组合等清洁漂白技术来取代.文中结合各类清洁漂白技术的特点,研究适用于各浆种的中浓氧脱木素、中浓过氧化氢等漂白技术,结合工程实践,提出适合我国国情的中浓纸浆少污染漂白技术及全无氯漂白技术,从而满足日益严格的环保要求,实现清洁漂白生产.

| Abstract: | Due to its high risks in environmental pollution,great consumption of water and energy,and its limited yields,the traditional bleaching technology(CEH) for low-consistency pulp by chloric agent is bound to be substituted by such technologies as oxygen delignification,chlorine dioxide bleaching,and hydrogen peroxide bleaching for medium-consistency pulp,or by the combined methods of these technologies.This paper analyzes the characteristics of each bleaching technology and investigates the oxygen delignification and hydrogen peroxide bleaching for the medium-consistency pulps with different stocks.Then,based on the engineering experience,the less-pollution bleaching technology and the total-chlorine-free bleaching technology suitable for the paper industry in China are presented,with the aim of meeting the increasingly strict environmental standards and implementing clean bleaching in paper industry. |
