A method to enhance the anaerobic degradation of antibiotics

Abstract

The invention belongs to the technical field of antibiotic biological treatment, in particular to a 2 A method for strengthening the anaerobic degradation of antibiotics by adding a small amount of CaO to the anaerobic fermentation of antibiotic-contaminated organic waste 2 , without weakening the anaerobic fermentation of organic waste, the use of CaO 2 React with water to produce the oxidation characteristics of hydroxyl radicals and the microaerobic environment created by the reaction to generate oxygen, and improve the efficiency of anti-biological anaerobic degradation. This method can be applied to anaerobic fermentation of antibiotic production waste and antibiotic-contaminated organic waste In the process, compared with other methods, the method proposed in the present invention to strengthen the anaerobic degradation of antibiotics by adding calcium peroxide is simple, easy to operate, low in cost, and has strong application value.

Description

technical field [0001] The invention belongs to the technical field of antibiotic biological treatment, and in particular relates to a method for strengthening anaerobic degradation of antibiotics. Background technique [0002] Antibiotics are widely used in the prevention and treatment of bacterial infectious diseases and in promoting animal growth. Nearly 90% of the world's antibiotic production is used in livestock and poultry farming. However, a considerable part of antibiotics in the poultry and livestock breeding industry is not fully utilized, and is excreted with animal feces in the form of drug prototypes or metabolites. Antibiotics present in the environment will produce huge environmental toxicological effects and induce bacterial resistance, thus seriously affecting the health of humans, animals and plants. [0003] Anaerobic fermentation technology is widely used in the field of organic waste treatment, and it is also one of the important means of harmless tre...

Chinese patent CN106754474 A discloses an antibiotic slag anaerobic fermentation accelerator and its preparation and application method. The main components of the accelerator include functional microorganisms, trace elements and carriers, and the dual regulation of functional microorganisms and trace elements is mainly used. Improve the anaerobic degradation of antibiotic residues, but the components of the accelerator are complicated and the preparation process is complicated; Chinese patent CN106540398 A proposes a method for anaerobic fermentation of antibiotic residues through alkali-heat combined pretreatment, through which the residues The residual antibiotics in the medium are basically completely removed, the antibiotic residue potency is reduced by more than 90%, and methane gas can be obtained, but it still has certain limitations, such as the need to invest a lot of energy and chemicals in the pretreatment process, thus increasing the Operating costs
