The invention discloses a method for degrading organic wastewater through excitation of peroxysulphate under the effect of ferrous molybdate. The method comprises the steps that peroxysulphate and ferrous molybdate are added into a wastewater solution, stirring is performed to enable the peroxysulphate and the ferrous molybdate to be subjected to a reaction, the peroxysulphate generates sulfate radicals and hydroxyl radicals with the strong oxidizing property under the effect of the ferrous molybdate, the sulfate radicals and the hydroxyl radicals further oxidize persistent organic pollutants in organic wastewater, and therefore the purpose of degrading the organic wastewater is achieved. The added ferrous molybdate continuously and efficiently catalyzes and activates the peroxysulphate under the normal temperature so as to degrade the organic wastewater and can be recycled after the reaction, the processing efficiency under the normal temperature is high, operation is easy, and the great application prospect
