摘要 近年来,沸石在污水处理领域得到了广泛的应用。但由于沸石的孔径小,通道易堵塞,对污染物的去除效果不理想,其吸附能力往往达不到要求。为了进一步提高沸石的离子交换、吸附等性能,从而提高对水中污染物的去除效率,须对沸石进行处理。简述了Fe、Mn、Cu、Ag、Ce、Al、La、Zn、Na和Ti 10种金属在天然沸石上的负载方法,前9种金属的负载方法主要是浸渍法,最后1种主要是溶胶-凝胶法。综述了经10种金属负载后的天然沸石对药物、染料废水、重金属、含酚废水、氨氮和挥发性有机物等污染物的去除情况和去除机理。同时,对负载型沸石在废水处理中的进一步发展提出了一定的看法和思考。

Abstract: Zeolite has been widely used in wastewater treatment in recent years. However, because of the small pore size, easy block of the channel, unideal removal effect of pollutants,the adsorption capacity of zeolite is often not up to the requirements. In order to further improve the properties of ion exchange and adsorption of zeolite and thus improve the removal efficiency of pollutants in water, it is necessary to treat zeolite. The loading methods of Fe, Mn, Cu, Ag, Ce, Al, La, Zn, Na and Ti on natural zeolite are introduced briefly. The loading methods of the first nine metals are mainly impregnation method, and the last one is sol-gel method. The removal mechanism of natural zeolite loaded with ten metals on drugs, dye wastewater, heavy metals, phenol wastewater, ammonia nitrogen, volatile organic compounds and other pollutants is reviewed. At the same time, the further development of loaded zeolite in wastewater treatment is discussed.
