NOVELTY - Preparation of antibiotic medicine slag, where the antibiotic is wet medicine slag as raw material involves: first absorbing and degrading antibiotic wet medicine slag as raw material and fermentating, sterilizing and deodorizing the dry degrade.    USE - For preparation of antibiotic medicine slag which is used for making insect, fish feed, or animal feed additive, animal excrement with mixed gas which is used as raw material to produce marsh gas, which is used as fertilizer of plants and flowers (all claimed).    ADVANTAGE - The method is scientific and reasonable, is cost effective. The obtained product is not only meets the discharge standard, but also opens up for use to obtain variable damage.    DETAILED DESCRIPTION - Preparation of antibiotic medicine slag, where the antibiotic is wet medicine slag as raw material involves: absorbing and degrading antibiotic wet medicine slag as raw material, adding bentonite and medical stone powder of a certain weight proportion to the receptacle, uniformly stirring, standing to precipitate, the antibiotic wet medicine slag to a residual explosive to degrade using neutralizing degradation; processing the antibiotic medicine wet slag progress and degraded, for acidic antibiotic wet medicine slag, adding proper edible alkaline substance to form medicine dreg to neutral, and further degrading the residual medicine ingredients which disappear for the basic antibiotic medicine dregs, adding proper edible acid material and DDS and the medicine dreg to neutral, and further degrading the residual medicine ingredients which disappear; adding certain proportion of yellow wine yeast and saccharifying DDG which is harmful bacteria in the wet dregs to ferment the beneficial bacteria in propagation, residual explosive further degradation; de-odorizing and removing peculiar smell from the slag, by adding a certain weight ratio of glucose, water, and removing wet antibiotic medicine, adequately digesting the antibiotic wet medicine slag residual explosive to obtain antibiotic medicine dregs, drying the wet medicine slag deodorized antibiotic, which is convenient to use, and convenient to store.
