摘要：

从造纸黑液中提取的木质素对糖蜜酒精废液有明显的脱色效果,但从造纸黑液中提取木质素时的工艺、黑液的品种以及黑液的新鲜程度等因素直接影响着木质素对糖密酒精废液的脱色效果。作者就以上的各种影响因素进行了定量和定性的讨论。

Abstract:

Lignin extracted from black liquor in paper-making has obvious decolorising effect on molasses alcohol wastewater. Many factors, such as the technology of lignin extracting, variety of black liquor and freshness of the black liquor, etc. can affect the decolorising efficiency directly. Quantitative and qualitative discussions about the above influential factors are made.

Key words: lignin, black liquor in paper-making, molasses alcohol wastewater, decolorising
