摘　　要：褐煤活性焦是一种以褐煤为主要原料制备的具有吸附和催化功能的新型环保材料,其特点是中孔发达,表面含有多元含氧官能团,优先吸附大分子难降解有机污染物,已广泛用于废气和废水的处理。褐煤活性焦处理难降解有机废水主要有煤化工废水、炸药废水、石油废水、印染废水等,其机理是氢键作用、化学吸附。褐煤活性焦吸附量较小,可通过改性、二次利用等提高吸附量。饱和活性焦可再生或资源化利用以提高利用率、减少二次污染。Lignite activated coke(LAC)is a kind of innovative environment protection material with adsorption and catalytic functions that prepared by lignite.LAC contains multiple oxygen-containing functional groups,predominant mesoporous and preferential adsorption macromolecular refractory organic pollutants,and it has been widely used in flue gas and wastewater treatment.The refractory organic wastewater mainly includes coal chemical industry wastewater,explosive wastewater,oil wastewater and dyeing wastewater.The mechanism is hydrogen-bond interaction and chemical adsorption.The adsorption amount of LAC is small and it can be improved by modification or reutilization.Saturated LAC can be renewable and recycled to improve the utilization rate and reduce the secondary pollution.
