摘要
采用热活化结合微波有机改性凹凸棒石黏土(凹土),突破了传统单纯物理改性或有机改性的局限性,提高了改性后凹土对苯酚的去除率,同时研究了凹土去除苯酚的最佳工艺条件,苯酚的去除率可达到99%以上,吸附后的污水符合国家污水排放标准。
The modified attapulgite was made by heat activation combined with microwave modification. The craft breached the limit of traditional method and could raise the removal rate of phenol in wastewater. By the orthogonal experiment, the best craft term were obtained. Under these circumstances, the phenol removal rate can get more than 99%. Then the absorbed water can meet the national waste water emission control regulations.
