Method for reinforcing anaerobic degradation of antibiotics

Abstract

The invention belongs to the technical field of antibiotic biological treatment, and particularly relates to a method for reinforcing anaerobic degradation of antibiotics. According to the method, a small amount of CaO2 is added in the anaerobic fermentation process of organic waste polluted by antibiotics; and on the premise of not weakening the anaerobic fermentation of the organic waste, the oxidization feature of CaO2 capable of producing hydroxyl radicals through reaction with water and the micro aerobic environment created by oxygen production in the reaction are used for improving theanaerobic degradation efficiency of the antibiotics. The method can be applied to the anaerobic fermentation process of antibiotic production waste materials and organic waste polluted by the antibiotics. Compared with other methods, the method for reinforcing the anaerobic degradation of the antibiotics through adding CaO2 provided by the invention has the advantages that simplicity and convenience are realized; the implementation is easy; the operation is simple; the cost is low; and high application values are realized.

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 CN106754474A discloses a kind of antibiotic slag anaerobic fermentation accelerator and its preparation and application method. Anaerobic degradation of antibiotic residues, but its accelerator components are complex and the preparation process is complex; Chinese patent CN106540398A proposes a method for anaerobic fermentation of antibiotic residues through combined alkali-heat pretreatment, after which the residues in the residues The antibiotics are basically completely removed, the potency of antibiotic residues 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 cost
