Problems solved by technology

[0005] The purpose of the present invention is to provide a method for treating antibiotic residues in order to solve the problem of low efficiency of microbial degradation of antibiotics. The present invention uses meat and bone meal as an additive to catalyze the degradation of antibiotics in antibiotic residues to achieve harmless treatment. The method of the present invention does not Adding bacterial agents, by adjusting the microenvironment of the bacteria residue to stimulate the naturally occurring microorganisms in the bacteria residue to achieve the degradation function

Embodiment 1

[0022] A method for treating antibiotic bacteria residues, specifically, 99 parts of antibiotic bacteria residues are fully pulverized, 1 part of meat and bone meal is pulverized, and then the two are fully mixed, and placed at 10°C-45°C for curing, and the meat and bone meal It can stimulate indigenous microorganisms to degrade antibiotics and carry out harmless treatment of bacterial residues.

[0023] The antibiotic residue used in this example comes from Shandong Lukang Medicine, and the initial penicillin concentration is 1650 μg / g. The meat and bone meal used in this example is obtained from Remsoil Company of Finland.

[0024] figure 1 It shows that within 60 days, the antibiotic concentration of the treatment group added with meat and bone meal compared with the control group without meat and bone meal has changed over time, and after 60 days, the antibiotic concentration in the antibiotic bacteria residue has decreased by 85.76%.

Embodiment 2

[0026] A method for treating antibiotic bacteria residues, specifically, 95 parts of antibiotic bacteria residues are fully pulverized, 5 parts of meat and bone meal are pulverized, and then the two are fully mixed, placed at 10°C-45°C for curing, and the meat and bone meal It can stimulate indigenous microorganisms to degrade antibiotics and carry out harmless treatment of bacteria residues. After a certain period of time, the concentration of antibiotics in antibiotic bacteria residues is reduced by 90.61%.

[0027] The antibiotic residue used in this example comes from Shandong Lukang Medicine, and the initial penicillin concentration is 1650 μg / g. The meat and bone meal used in this example is obtained from Remsoil Company of Finland.

Embodiment 3

[0029] A method for treating antibiotic bacteria residues, specifically, 90 parts of antibiotic bacteria residues are fully pulverized, 10 parts of meat and bone meal are pulverized, and then the two are fully mixed, and placed at 10°C-45°C for curing, and the meat and bone meal It can stimulate indigenous microorganisms to degrade antibiotics and carry out harmless treatment of bacteria residues. After a certain period of time, the concentration of antibiotics in antibiotic bacteria residues is reduced by 95.83%.

[0030] The antibiotic residue used in this example comes from Shandong Lukang Medicine, and the initial penicillin concentration is 1650 μg / g. The meat and bone meal used in this example is obtained from Remsoil Company of Finland.

Abstract

The invention relates to an antibiotic microbe dreg treatment method which comprises the following steps: mixing meat and bone meal adopted as an additive with antibiotic microbe dregs, and exciting naturally existing microorganisms in the microbe dregs by adjusting the microenvironment of the microbe dregs so as to degrade antibiotics. Compared with traditional physical, chemical and microbiological treatment methods of antibiotics, the method has the characteristics of high remediation efficiency, low cost, strong operability, low environmental risk and the like, has good environmental benefits, social benefits and economic benefits, and provides a new method for simultaneously treating two production byproducts, namely antibiotic microbe shroom dregs and meat and bone meal.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a method for treating antibiotic scum. Background technique [0002] In the production of antibiotics, it is estimated that the by-product bacteria residue is ten times its production. Antibiotic residues are clearly listed as hazardous waste due to their drug residues. Bacterial residues generally contain nutrients such as antibiotic-producing bacteria, antibiotic residues, and culture medium substrates (Zou Shujuan et al., 2018). At present, the treatment and disposal technologies of antibiotic residues include incineration, landfill, fertilizer, feed, and energy (Zhu Pei et al., 2013, Ma Silu et al., 2018, Liu et al., 2019). Incineration, pyrolysis, hydrothermal and other methods not only consume a lot of energy, but also the waste gas generated needs further treatment to avoid air pollution. The use of bacterial residues to produce fertilizers, feeds and ...
