A copper-doped ferrous metal organic framework, a method for preparing same, and a method of using same for activating persulfate to treat organic wastewater, relating to the technical field of water pollution control. The copper-doped ferrous metal organic framework is prepared by means of solution impregnation, and copper ions are efficiently loaded by using a relatively large specific surface area and relatively abundant cavity structures of the ferrous metal organic framework. According to the method, a ferrous active center in unsaturated coordination on the ferrous metal organic framework and loaded copper ions are used as catalyst bodies, and persulfate is efficiently and continuously activated by means of catalytic synergism between the ferrous active center and copper ions, to generate sulfate radicals, thereby degrading organic pollutants. The method is applicable to organic wastewater treatment with the advantages of high catalytic activity, good durability, easy operation, and convenient recycling
