The present application relates to the field of biotechnology science, and more particularly to an ecological technology method for efficiently reducing antibiotic-resistant genes in cow dung; by introducing a certain amount of angelica residue and cow dung to improve the self-pollution control ability of earthworms, the antibiotic-resistant gene pollutants in the cow dung are efficiently eliminated, the removal rate of beta-lactam antibiotic-resistant genes can be increased to more than 80%, the removal rate of sulfonamide and tetracycline-resistant genes also reaches 60%-70%, and the reduction of mobile transmission elements is also increased from about 30% of the conventional conversion method to more than 60%, and further, the present application can also make full use of traditional Chinese medicine residue and cow dung waste, so as to achieve the purposes of waste-to-resource, harmless treatment and safe resource utilization.

The utility model is suitable for the technical field of treatment equipment, and provides a composting device. The composting device comprises a composting container which is provided with a composting space for accommodating composting materials and can rotate; the cutting piece is arranged in the composting space, can rotate relative to the composting container and is used for cutting the composting materials in the composting space; the spraying piece is arranged in the composting space and is used for spraying liquid into the composting space. The rotating composting container can enable composting materials in the composting space to be continuously turned over and mixed, the rotating cutting piece can cut and crush the composting materials, and under the combined action of the composting container and the cutting piece, the contact area of the composting materials, air and microorganisms can be remarkably increased, so that the composting materials can be effectively decomposed. Therefore, the decomposition effect of microorganisms in the composting process is effectively accelerated, the time consumed by composting is shortened, and the composting efficiency is improved.
