Harmless and resourceful treatment method for antibiotic residue

Abstract

A harmless and resourceful treatment method for antibiotic residue includes steps as follows. The antibiotic residue is dried and crushed to obtain a dry powder of antibiotic residue. The dry powder of antibiotic residue is heated to a temperature of 400-800° C. to perform an isothermal pyrolysis treatment under an inert atmosphere. Condensable gas in the volatile substances released during the pyrolysis treatment is collected using a condensing device to obtain a condensable bio-oil product, non-condensable gas in the volatile substances is collected using a gas bag to obtain pyrolysis gas, and the residual substances obtained after the pyrolysis treatment are as a biochar product. The treatment method addresses the issues of incomplete degradation of the antibiotic residue, complex processes, high difficulty in resource utilization, and resource wastage in traditional treatments of the antibiotic residue, thereby achieving the goals of harmlessness and resource utilization of the antibiotic residue.
