绿液预处理及石灰质量对白泥应用性能的影响

Impact of Green Liquor Pretreatment and Lime Quality on White Mud Properties

绿液中Fe2+的存在和绿液的澄清度对提高苛化后白泥的应用性能有一定的影响,选择过氧化氢为氧化剂对绿液进行氧化处理,可以降低Fe2+的浓度,进而对提高苛化白泥的白度产生积极的影响;采用絮凝剂对绿液进行净化处理可除去其中的可絮凝性杂质,有利于改善苛化白泥的性能指标;苛化时使用的石灰质量及其粒度对苛化白泥的应用性能有较明显的影响。

The impact of green liquor pretreatment and lime qual it y on white mud properties is studied in this paper.The amount of ferrous ion( Fe 2+ )content in green liquor and the clarification degree of green liquor can i nfluence some applied properties of white mud in some extent.The applied qualit y of white mud can be improved when green liquor is oxidized with hydrogen perox ide and the applied properties of white mud can also be improved by using some f locculants to clarify green liquor.Furthermore,the quality of lime has a signi ficant influence on the applied prop-erties of white mud.
