摘　　要：用铝盐和银盐对钙基膨润土进行化学、物理改性，制备出一种复合型废水处理剂AAB，探讨了其处理染料废水的适宜条件。结果表明，在pH值7～9、温度20℃左右、AAB投加量3．0g／L、时间60min的条件下，处理4种浓度为500mg/L的染料废水，脱色率可达96％以上，COD去除率接近88％。Calcium based bentonite was modified with aluminium and silver salts. The generated Ca-bentonite/Al-Ag composite （AAB） was further used as an agent for dye wastewater treatment. Four different samples of dye wastewater （each with a concentration of 500 mg/L） were treated with AAB. The results showed that when the pH value of these samples was 7-9 and AAB was in a dosage of 3.0g/L for each sample, the decoloration of these samples was above 96% and the decrease of COD was by 88% at 20℃ for 60min.
