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.
