摘要
提出了采用酸化法从造纸黑液中提取木素的最佳工艺条件,并结合生产实际进行了分析.黑液经酸化后,能去除大量有机物,对减轻黑液污染具有明显的效果,同时回收木素创造了较好的经济效益.
This paper describes an optimal technology of extracting wood-cellulose from bkck papermaking liquor by oxidation process, and analysis by actual work. After black liquor is acidified, a large amount of organic compounds are removed, evident effect to decrease pollution appears, and better economic efficiency is produced.
