Problems solved by technology

Incineration is the process of oxidizing and burning antibiotic residues to form organic matter or carbon dioxide. Although this method can realize the harmless treatment of waste, it requires high energy consumption and causes serious waste of resources; Antibiotic residues are used as feed. However, this method tends to enrich the antibiotics and degradation products in animals, which will lead to drug resistance in humans. Therefore, the possibility of using antibiotic residues as feed has also been widely questioned; Energy conversion is the process of using anaerobic digestion to recover biogas or using pyrolysis technology to recover combustible gas and fuel oil. Although this method has certain effects, it still has problems such as low organic matter release rate and low yield of biogas and combustible gas; Through microbial fermentation, the organic matter and residual antibiotics in the antibiotic residues are degraded to form organic fertilizers, which is a relatively good treatment method
However, in the prior art, the fermentation time is usually longer when the antibiotic slag is fertilized, and the fermentation process often produces odors; in addition, the organic fertilizers formed generally have poor sensory quality and substandard quality (for example, there are still antibiotic residues) etc.) and defects such as unstable quality

Embodiment 1

[0032] Add 4 mL of concentrated nitric acid to 100 mL of vancomycin fermentation bacteria residue, reflux at a reflux temperature of 100°C for 90 minutes, collect the precipitate after precipitation and filter it with filter paper (quantitative slow-speed filter paper, pore size 1-3 μm) to obtain bacteria residue without antibiotic residues. The bacterial residue was detected by high performance chromatography and mass spectrometry, and no antibiotics were detected. The technical index detection results of the bacterial residues without antibiotic residues are shown in Table 2.

Abstract

The invention relates to the technical field of antibiotic mushroom dreg recycling, in particular to an antibiotic mushroom dreg fertilizer conversion method and an organic fertilizer, S1, antibiotic mushroom dregs and an effective amount of concentrated nitric acid are mixed, refluxed, precipitated and filtered to obtain mushroom dregs without antibiotic residues; s2, directly using the mushroom dregs without antibiotic residues as an organic fertilizer, or further compounding and mixing the mushroom dregs with nutritional raw materials to prepare a compound organic fertilizer. According to the method for treating the antibiotic mushroom dregs into the fertilizer, the dehydration performance of the mushroom dregs can be greatly improved, meanwhile, the antibiotic residual quantity in the treated antibiotic mushroom dregs is effectively eliminated, meanwhile, the treatment efficiency is high, and the method is suitable for treating the antibiotic mushroom dregs of different sources into the fertilizer.

Description

technical field [0001] The invention relates to the technical field of resource utilization of antibiotic bacterial residues, in particular to a method for fertilizing antibiotic bacterial residues and an organic fertilizer. Background technique [0002] The production process of antibiotic APIs includes unit processes such as fermentation, extraction, and refining. During the fermentation process, a large amount of antibiotic fermentation bacteria residues are produced. Antibiotic fermentation residue is mainly composed of fermentation mycelium, residual antibiotics, remaining medium and other metabolites. If the antibiotic residues are not disposed of properly, the residual antibiotics in them may induce the production of drug-resistant bacteria and super bacteria. Therefore, antibiotic residues are strictly regulated as hazardous solid wastes. [0003] The antibiotic-fermented wet mushroom residue is rich in organic matter and has the value of resource utilization; how...
