The invention discloses a processing method of lincomycin fungus dregs, effectively settling the problem of degradation and clearance of residual lincomycin inside the fungus dregs and enabling the regeneration and reuse of wastes. The processing method of lincomycin fungus dregs can be realized through the following steps: the lincomycin fungus dregs, EM bacteria stock solution, accessories and water are used as materials; wherein, the total weight ratio of the lincomycin and the accessories is 1 to 3:1; the accessories comprise bran, brown sugar, sodium bicarbonate, table salt and peanut shell with the weight ratio of 50:6:3:16:125; wherein, the bran and the peanut shell are pulverized, then the sodium bicarbonate and table salt are added to the lincomycin fungus dregs in series, 40 to 50ml EM bacteria stock solution is measured for 1kg lincomycin fungus dregs added with brown sugar and diluted by water to 250ml, forming EM bacteria stock diffusion solution; then the EM bacteria stock diffusion solution is added to the mixture and mixed uniformly, added with water, and stored in a vessel for fermentation. The processing method of lincomycin fungus dregs has the advantages of simple method, waste reuse, and great economic and social benefits.
