摘　　要：将钙基膨润土酸性活化,用其处理染料废水,其一次性COD去除率可达62%,色度去除率可达83%。若再对其进行无机柱撑,COD的去除率可达81%以上,色度去除率可达98%以上。其处理后的染料废水达到国家工业废水排放标准。In the treatment of dyestuff waste water with acid-activated calcium base aha-mud,its COD removing rate could reach to 62% and its decoloring rate could reach to 83%.If the acidified alta-mud be post-propped up again inor ganically,its COD removing rate could be raised to 81% or more and its decoloring rate could be raised to 98% or more. The so treated dyestuff waste water could reach the national drainage standard for industrial waste water.
