Abstract

The invention provides a method for treating antibiotic residues by an enzymic method. The method comprises the following steps: mixing an enzymic preparation combination with water according to a volume ratio of 1:50 to obtain an enzymic preparation combination solution; uniformly spraying the enzymic preparation combination solution onto fresh antibiotic residues by a sprayer, and stirring for 0.5-1h mechanically, wherein 1-5L of the enzymic preparation combination solution is added to each ton of antibiotic residues; putting the well stirred antibiotic residues to a storage tank, and reacting for 1-4h at the temperature of 30-50 DEG C under the condition of natural pH value, wherein the antibiotic residues are at a natural solid-liquid separated state at the end of the reaction, supernate can be used for biogas fermentation, and solids are used for preparation of organic fertilizers. By the method disclosed by the invention, pollution to the earth surface and air, caused by the emission of cassava waste residues, can be solved to a great extent, and dual effects of reutilization of waste residues and energy conservation and emission reduction can be achieved.

Description

technical field [0001] The invention relates to a method for enzymatically treating antibiotic dregs, belonging to the field of biomedicine. technical background [0002] Antibiotic dregs are filter residues of fermented antibiotic raw materials, and its main components are: corn steep liquor, peptone, starch, soybean oil, soybean cake powder and other biological media. Since the moisture content in the separated antibiotic dregs reaches 90%, and the solid dregs are uniformly dispersed in the liquid in the form of a suspension, most of them have been treated by stacking or deep burying in fermentation tanks, which not only wastes antibiotics There are effective nutrients in the dregs of antibiotics, and the effects of medicinal chemicals and complex microbial flora in the discarded antibiotic dregs have left long-term hidden dangers of poisoning to humans. Due to the increasing investigation and punishment by the national environmental protection department, various antibio...
