A kind of resource treatment method of antibiotic bacteria residue

Abstract

The invention provides a resourceful treatment method for antibiotics mushroom dregs, wherein mushroom dregs produced during production of antibiotics such as penicillin, erythrocin and cephalosporin are treated by the steps of intensified hydrolysis, mushroom dregs blending, two-phase anaerobic digestion, deep dehydration, resource utilization and the like. Aiming at the practical problems of a large quantity of antibiotics mushroom dregs and great treatment difficulty, the antibiotics mushroom dregs are subjected to harmless and resourceful treatment, thus providing basis for difficulties urgent to be solved of pharmaceutical enterprises.

Description

technical field [0001] The invention belongs to the field of solid waste treatment, and in particular relates to a method for recycling antibiotic bacteria residues. Background technique [0002] Antibiotic mycelium waste is the waste in the process of producing antibiotics. The main components of the fungal residue are mycelium, unused medium (such as soybean meal, corn steep liquor, peanut cake powder, glucose, etc.), fermentation process Metabolites produced, degradation products of the medium, flocculants, acidifiers, filter aids added during the extraction process, residual organic solvents, residual antibiotics and metabolic intermediates, etc. According to the 2008 edition of the "National List of Hazardous Wastes", the 2012 "Pharmaceutical Industry Pollution Prevention and Control Technology Policy", and the 2014 edition of the "National List of Hazardous Wastes" being revised, antibiotic residues are hazardous wastes. As hazardous wastes, the legal means of disposal...

Problems solved by technology

[0003] As a major producer of antibiotics, my country has no mature treatment technology and method for antibiotic residues. Due to its rich nutrition, crude protein content is about 40%, and various essential amino acids, vitamins and trace elements are rich and balanced. Antibiotic residues are biological It is an excellent raw material for comprehensive utilization. It is a waste of resources to directly incinerate or landfill it. Moreover, the incineration method is costly and prone to produce a large amount of harmful gases. The landfill method occupies a large amount of land resources and is easy to pollute groundwater. Therefore, the development of antibiotic bacteria The new technology of slag resource treatment is imminent

Patent CN201110409090.6 discloses a method for treating cephalosporin C production residues by thermal alkaline hydrolysis-press filtration. Although this method can eliminate antibiotic residues in cephalosporin residues, the disadvantage is that the residues only undergo one step of heating Alkaline hydrolysis, without the process of anaerobic composting, the residual solvents and metabolites in the bacterial residue cannot be converted into small molecular substances with high bioavailability

Patent CN201310095797.3 discloses a method for treating cephalosporin residues by thermal alkaline hydrolysis and anaerobic digestion. The residual biogasporin C produced by this method is extremely low, but the discharged biogas residues have not been dehydrated. It is convenient for transportation, storage and use, but has not really achieved reduction
