A kind of treatment process of antibiotic bacteria residue

Abstract

The invention relates to the field of organic waste treatment, and discloses a treatment process for antibiotic residues, wherein the treatment process includes: in the presence of alkaline substances, under airtight conditions, at 40-260 ° C, the The bacterial residue of antibiotics to be treated is degraded, and then the degradation products are separated to obtain solid-phase material flow and gas-phase material flow, and the gas-phase material flow is subjected to post-treatment. 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 residues are solid wastes 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 soli...

Problems solved by technology

However, the treatment of antibiotic residues 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

Second, the stacking of antibiotic residues and the treatment process will release unpleasant odors, pollute the surrounding environment, and make the treatment process more technically difficult
