摘　　要：对产自辽宁某地的钙基膨润土通过不同程度的改性处理,用于处理染料废水,比较了不同改性后的膨润土处理染料废水的效果。处理效果最佳的是柱撑酸化膨润土,其对染料废水COD的去除率可达80%以上,色度去除率可达95%以上。The differently modified calcium-based bentonite from Liaoning Province was used to treat dyeing wastewater. The effects of the treatment show that the best effect is achieved by pillared acidified bentonite, whose COD removal efficiency is more than 80% and chroma removal efficiency is more than 95%.
