膨润土对酸性蓝染料废水的脱色研究

Studies on the Decolouration of Bentonite to Dyeing Waste Water

采用酸活化膨润土处理酸性蓝印染废水 ,其脱色效果很好 ,色度去除率可达 96% ,且CODCr去除率可达63 %。若再经絮凝剂絮凝处理后 ,色度降至 2 0倍 。

In this paper,the bentonite is used to treat dyeing waste water.After treated,the moved efficiency of chromaticity was 96% and the moved efficiency of COD Cr was 63%.
