The invention discloses a processing technology of the waste dregs of lincomycin. The technology comprises the steps that: the waste dregs of the lincomycin, the bacterial liquid of EM and the culture solution of alcohol yeast are mixed according to the proportion of 100: (0.5 to 1.5): (3 to 5) and stirred uniformly, and solid anaerobic fermentation is carried out for over 96 hours to remove antibiotics left in the waste dregs; the ferment material is diluted by water and prepared into 10 to 30 percent of a suspension which is uniformly stirred, and sheared and broken mechanically at high speed, reticular mycelium is cut into 'bacillus' shape by observation under a microscope, and by chemical detection: chemical oxygen demand (COD for short) is over 5000; a sheared solution is mixed with the high concentration organic wastewater of lincomycin by the proportion of 10 to 40: 100 put into a jar to carry out anaerobic fermentation and produce biogas. The method is practical, the gas production rate thereof is improved by over 30 percent, the indexes of an anaerobic system, such as the removal rate of COD, PH, degradation rate and sludge discharge, etc. are not affected, and facilitiesrun normally.
