The invention discloses a coal-fired power generation coupling treatment method for kitchen garbage after wet anaerobic fermentation. The method comprises the following steps: crushing the kitchen garbage, selecting magnetic metal impurities in the garbage through a magnetic separation device, then carrying out slurry making treatment, wherein blending liquid and the garbage are adopted for blending and pulping in the treatment process, conveying the prepared pulp to an impurity removal device, and carrying out separating for removing floating impurities and sinking heavy substances in the pulp. By improving the coal-fired coupling power generation treatment method, the advantages of a high-efficiency generator set of a coal-fired power plant can be fully exerted, meanwhile, the load rate of the generator set of the coal-fired power plant can be improved, then the power grid dispatching requirement can be better met, in addition, air pollution caused by direct emission of tail gas can be prevented, so that th
