利用燃煤烟道气提高膨润土处理造纸黑液的综合效益

Using Flue Gas to Increase the Integrate Benefit of Treating Black Liquor from Paper Industry with Bentonite

将燃煤烟道气应用于黑液的处理过程，研究了膨润土处理黑液的适宜条件．试验结果表明：烟道气的使用有利于提高处理的效果，经处理后的分离液及沉降物易于再利用。

The flue gas was applied to the treatment process for the black liquor. The conditions appropriate for bentonite to treat black liquor were investigated. The experimental results showed that the effect of this treatment was increased. The seperated liquor and its precipitates after treatment can be reused easily. So the integrated benefit were gained.
