造纸碱回收白泥综合治理技术的研究与应用

摘要

The current status of comprehensive utilization technologies of lime mud from alkali recovery in China was summarized, and the practical recycling application of lime mud was also introduced in this paper. The feasible technologies and the problems of recycling utilization of lime mud were discussed, and solutions for those technical problems were put forward. The technologies of preparing precipitated calcium carbonate (PCC) from lime mud were primarily presented based on two typical projects.%对造纸碱回收白泥综合治理技术的研究现状与生产实际应用情况进行了综述,探讨了白泥资源化回收利用的可行方案及存在的问题,分析了白泥资源化回收利用过程中相关技术问题的解决途径.同时重点介绍了白泥精制CaCO3新技术和国内两家稳定运行的应用示范工程.
