Degradation method of livestock and poultry manure antibiotics

Abstract

The invention relates to a degradation method of livestock and poultry manure antibiotics in particular to a method for producing a safe organic fertilizer by disinfecting livestock and poultry manureat normal temperature and effectively removing antibiotics. The method comprises the following steps: mixing an alkali carbonate-hydrogen peroxide mixed reagent in livestock and poultry manure, or firstly mixing hydrogen peroxide and then mixing an alkali carbonate solution, and standing or mixing and stirring for more than 1 hour so as to obtain the organic fertilizer with the antibiotic contentof less than 10ppb. According to the method, greener and safer carbonate peroxide is ingeniously utilized to destroy the antibiotic structure in the livestock and poultry manure, the activity and thetoxicity of antibiotics are reduced, and germs in the manure are sterilized and inactivated. The simple process does not cause secondary pollution to the environment, the antibiotic content of the treated livestock and poultry manure can be reduced from 4300ppb to about 10ppb and is far lower than the antibiotic content requirement of 750ppb, and the degradation rate is 99.77%; the content of bacteria can be reduced from 9.2 billion / g to below 30,000 / g, and the sterilization rate can reach 99.997%. Use is safer, and the potassium carbonate / hydrogen peroxide compound is more suitable for beingused as fertilizer.

Description

technical field [0001] The invention belongs to the field of organic fertilizer production, in particular to a method for effectively degrading antibiotics in livestock and poultry manure and biomass and simultaneously normal temperature sterilization to produce safe organic fertilizers, in particular to a method for degrading antibiotics in livestock and poultry manure. Background technique [0002] With the development of intensive farming, the use of veterinary antibiotics is becoming more and more common. However, antibiotics cannot be completely absorbed and degraded by animals, and most of them are still excreted in feces and urine in the form of prototypes or metabolites, resulting in excessive antibiotics in livestock and poultry manure. On the other hand, there are still a large amount of antibiotics that need to be effectively treated in the fermentation waste residue of antibiotic production enterprises. At present, antibiotics widely used in livestock and poultr...

AI Technical Summary

Problems solved by technology

Therefore, there are safety hazards in the use of livestock and poultry manure, urine and fermentation waste residue from antibiotic enterprises, and there is no safe and efficient treatment method, which leads to the prohibition of livestock and poultry manure as fertilizer, and the use of fermentation waste residue as fertilizer is difficult

[0003] In the prior art, sodium percarbonate, potassium percarbonate or calcium percarbonate are generally used for oxidative degradation of feces, or hydrogen peroxide and some additives are used for oxidative degradation of feces, but the degradation effect is not good, and sodium percarbonate is used to degrade the feces. The cost of antibiotics is relatively high, the time is relatively long, and it is difficult to carry out effective degradation reaction at room temperature, so it is necessary to develop a more efficient, economical and convenient method for the degradation of antibiotics in feces
