Abstract

The invention belongs to the technical field of solid waste treatment, and discloses a harmless treatment method for macrolide and fluoroquinolone antibiotics in livestock manure, which realizes resourceful treatment of the livestock manure by adopting microbial fermentation and hermetia illucens culture, and realizes harmless treatment of the livestock manure by virtue of the biological decomposition and biological conversion effects of microorganisms and hermetia illucens, which realizes efficient degradation of the residual antibiotics, does not need to add any chemical substances in the whole process, does not need to hold various reaction conditions such as temperature, saves the livestock manure treatment cost, reduces the treatment energy consumption, and greatly reduces the antibiotic content of the treated livestock manure, and finally, no waste is generated in the whole livestock and poultry manure treatment process, growth of hermetia illucens is achieved after hermetia illucens is bred, the bred hermetia illucens has certain economic value, good economic benefits can be generated, and therefore the method has good application and popularization value.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a harmless treatment method for macrolides and fluoroquinolone antibiotics in poultry manure. Background technique [0002] With the rapid development of large-scale livestock and poultry breeding in China, the harmless treatment and resource utilization of farm manure are of great significance to reduce environmental pressure. Moreover, the State Council issued the "Opinions on Accelerating the Resource Utilization of Livestock and Poultry Breeding Wastes", which clearly stated that by 2020, the comprehensive utilization rate of livestock and poultry manure in the country will reach more than 75%, which shows that it is imperative to implement the resource utilization of livestock and poultry manure. In line with the principle of "reduction, harmlessness, and resource utilization", the resource utilization of livestock and poultry manure can not only turn waste int...
