The invention belongs to the field of environment-friendly materials, and discloses a non-metal modified ferronickel spinel Fenton catalyst. The method comprises the following steps: a, preparing thermal stripping polymer carbon nitride; b, dispersing the thermally stripped polymer carbon nitride in ethanol for ultrasonic treatment to obtain a solution A; c, dissolving nickel nitrate hexahydrate and ferric nitrate nonahydrate in ethanol to obtain a solution B, and slowly adding the solution A into the solution B to obtain a mixed solution C; d, adjusting the pH value of the solution C by using a 6mol/L NaOH solution to obtain a solution D; and e, putting the solution D obtained in the step d into a hydrothermal kettle taking polytetrafluoroethylene as a lining, carrying out hydrothermal treatment for 10-36 hours at the temperature of 100-250 DEG C, and carrying out suction filtration and vacuum drying to obtain the non-metal modified ferronickel spinel Fenton catalyst. The non-metal modified ferronickel spine
