A kind of treatment process of antibiotic bacteria residue

Abstract

The invention relates to the field of organic waste treatment, and discloses a process for treating antibiotic residues, wherein the treatment process includes: degrading antibiotic residues to be treated at 100-260°C under airtight conditions, and then The degradation products are separated to obtain a solid-phase material flow and a gas-phase material flow, and the gas-phase material flow is post-processed. Through the above technical proposal, the residual antibiotics in the antibiotic residues can be effectively degraded while the organic nutrients therein can be effectively retained, which provides a good precondition for the harmless utilization of the residues. Furthermore, the process of the present invention can effectively avoid the problem that the fungus residue releases an unpleasant smell during and after the treatment, and the treated fungus residue has no odor and is environmentally friendly.

Description

technical field [0001] The invention relates to a process for treating organic waste, in particular to a process for treating antibiotic residues. Background technique [0002] Antibiotic residue is a solid phase waste produced during the production of antibiotics by microbial fermentation. China is the largest country in the production of antibiotics. The green degradation and utilization of antibiotic residues is a major challenge for domestic antibiotic manufacturers. [0003] Antibiotic residues are mainly composed of microbial cell tissue, residual medium, and solid phase residues mixed in the medium during the production process, such as filter aids. The components of the antibiotic bacteria residue include: protein, fat, carbohydrate, chitin, vitamins, minerals and residual antibiotics derived from microorganisms and culture medium. Wherein, the moisture content of the antibiotic bacteria residue is usually about 70-95% by weight. The proportion of crude protein in...

Problems solved by technology

[0007] Although the existing antibiotic residue treatment technologies include incineration technology, fertilizer technology, landfill and energy technology, etc., however, the treatment of antibiotic residue still faces many challenges

First of all, for the antibiotics remaining in the bacterial residue, except for incineration and carbonization heat treatment, it is difficult to effectively degrade in the existing technical solutions, and will re-enter the environment and become a hotbed for the cultivation of drug-resistant microorganisms

Therefore, the harmless utilization of bacterial residues first needs to effectively degrade the antibiotics; second, the stacking and processing of antibiotic residues will release unpleasant odors, pollute the surrounding environment, and make the processing process face greater technical challenges. difficulty
