摘　　要：化学制浆法是造纸行业中广泛采用的纸浆制造工艺,其中的漂白工序传统上普遍使用元素氯进行漂白,并利用所生成的氯气作为漂白剂,这种漂白方式会产生大量有毒性的有机卤化物,包括强致癌物二噁英等。鉴于次,近年来用二氧化氯为漂白剂的无元素氯漂白工艺开始被大量引入造纸行业,作为漂白工序的替代技术。通过研究无元素氯漂白工艺各个工段的工艺特点,归纳出无元素氯漂白纸浆在技术及环境成本综合考虑基础上的合理性,从而为其作为未来一段时期内造纸企业特别是中小型企业,为符合最新产业政策和环保标准,而对传统元素氯漂白工艺进行淘汰升级的工艺路线提供科学的参考。Chemical pulping is a pulp manufacturing process widely used in the paper industry,in which the bleaching process traditionally uses elemental chlorine bleaching,the use of chlorine gas as a bleaching agent,this bleaching method will produce a large number of toxic organic halides,including strong carcinogens dioxins.In view of the second,in recent years,the use of chlorine dioxide as bleach agent element-free chlorine bleaching process began to be widely introduced into the paper industry,as an alternative technology for bleaching process.By studying the process characteristics of each section of element-free chlorine bleaching process,the rationality of element-free chlorine bleaching pulp on the basis of comprehensive consideration of technical and environmental costs is concluded.In order to comply with the latest industrial policies and environmental protection standards,and to provide a scientifi c reference for the process route of eliminating and upgrading the traditional element chlorine bleaching process as a papermaking enterprise,especially small and medium-sized enterprises,in the future period.
