The invention discloses a preparation method of an electro-Fenton cathode material based on a carbon felt loaded with cobalt nanoparticles and an application of the electro-Fenton cathode material insewage treatment. The preparation method comprises the following steps: cutting a carbon felt material according to specifications, and carrying out soaking pretreatment in deionized water and ethanol; soaking the pretreated carbon felt material in a potassium hydroxide solution; putting the carbon felt material into a tubular furnace, and firing the tubular furnace in a nitrogen atmosphere; cleaning and drying the carbon felt material for later use; soaking the carbon felt material in a methanol solution of cobalt nitrate and polyvinylpyrrolidone; adding a methanol solution of dimethylimidazole into the original soaking solution, and continuing to soak the carbon felt material; depositing a layer of cobalt-dimethylimidazole metal organic framework compound on the surface of the carbon felt through the soaking rea
