Title: Eco-Friendly Bleaching Stage of Pulp——Chlorine Dioxide Bleaching
Abstract: Chlorine dioxide bleaching was one of the main bleaching stage in the ECF bleaching processes.It has been widely used in the multistage bleaching.Compared with chlorine dioxidebleaching,the production of AOX(adsorbable organic halides) in chlorine bleaching was more with the same and effective usage of chlorine.Chlorine dioxide has strong oxidation of strong delignification capacity and delignification selectivity.Using of buffer system in the process of ClO 2 bleaching was better for the stability of pH value.In ClO 2 bleaching process,amounts of AOX were reduced,because dimethyl sulfoxide(DMSO),hydrogen peroxide and NaClO 2 were added as bleaching additive agents.ClO 2 production equipment nationalization,and flexible bleaching process is the trend of future development.
