Antibiotic residue treatment process

Abstract

The invention relates to the field of organic waste treatment, and discloses an antibiotic residue treatment process comprising the steps of degrading antibiotic residues to be treated at 40-260 DEG C under the conditions of existence of alkaline matter and seal, then separating degradation products to obtain solid phase material flow and gas phase material flow, and performing post-treatment for the gas phase material flow. Through the above technical scheme, organic nutrients in the antibiotic residues can be reserved effectively while degrading the antibiotic residues, and good preconditions are provided for harmless utilization of residues. Moreover, in the process disclosed by the invention, the problem that the residues have disgusting smell can be avoided effectively in the treatment process and after treatment; the residues treated are free of odor and environment-friendly.

Description

technical field [0001] The invention relates to a process for treating organic wastes, in particular to a process for treating antibiotic bacterial 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, and the green degradation and utilization of antibiotic residues is a major challenge facing domestic antibiotic production enterprises. [0003] Antibiotic slag is mainly composed of microbial cell tissue, residual medium, and solid phase residues mixed in the medium in the production process, such as filter aids. The components of the antibiotic bacterial residue include: proteins, fats, carbohydrates, chitin, vitamins, minerals and residual antibiotics derived from microorganisms and culture medium. Wherein, the moisture content of the antibiotic bacterial residue is usually about 70-95% by weight. The proportion o...

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
