摘　　要：采用无机陶瓷膜提纯凹凸棒石黏土,将提纯后的凹凸棒土用于染料废水处理。结果表明,当凹土投加量为3.0 g,染料pH值为10,振荡速率为150 r/min,吸附时间为90 min时,膜分离技术提纯后的凹土对印染废水COD值降低率约为85%,脱色率约为95%,优于抽滤方法提纯凹土。The microfiltration separation process of attapulgite clay was studied with inorganic ceramic membrane and using purified attapulgite clay to treat the dyeing wastewater. The results indicated that when attapulgite dosage was 3 g, pH value was 10, agitation rate was 150 r/min, adsorption time was 90 min, attapulgite purified by membrane separation technology could effectively reduce 85% COD value and chromaticity removal was more than 95 %, which was superior to attapulgite purified by traditional technology.
