| 摘 要： | 该文讨论了凹凸棒土的改性方法，利用改性凹凸棒土对染化废水进行了吸附脱色性能研究，考察了改性方法，ｐＨ值、凹凸棒土投加量、吸附时间等因素的影响。结果表明：改性凹凸棒土对染化废水ＣＯＤｃｒ和色度有较好的去除能力，ＣＯＤｃｒ去除率可达８０％，脱色率达９５％以上，该吸附剂的静态吸附行为符合Ｆｒｅｕｎｄｉｃｈ吸附等温式。本研究对对凹凸棒土的应用开发提供了有价值的实验数据。

| Abstract: | The methods of modifying attapulgite and treating dyeing wastewater are studied in this paper.The results show that the modified attapulgite used in 1% removes COD and color from dyeing wastewater by 80% and 95% respectively.The process of adsorption can be stated by an expression similar to Freundlich model.This research provides valuable experimental data for modifying natural absorbents and applying them to treating dyeing wastewater. |
