有机交联膨润土对预处理造纸黑液COD的吸附研究

Study on Treatment Black Liquor Acid-Flocculating Paper Manufactured by Organic Cross-Linked Bentonite

主要探讨了有机交联膨润土吸附剂（简称TBC）对经酸化絮凝后的造纸黑液进行处理的研究。当pH=4．5，TBC用量为24g·1－1H2O，常温搅拌吸附60min后，其对COD的吸附效率可达61．5％，吸附容量为549．3mgCOD·g－1。

This paper focuses on the treatment for the black liquor of acid-flocculating paper manufactured by organic cross-linked bentonite (TBC). When 24g TBC was used for 1 litre organic-containing solution with 21424mg. L-1 of cod,pH= 4. 5,t = 60 min the absorption amount was 549. 3 mgcod. g-1TBC. the absorptional rate was 61. 5 %.
