The result shows that the resistance genes contained in the kitchen waste are various, the kitchen waste contains 171 ARGs and 32 MGEs, and the abundance of ARGs in the storage process is obviously increased to 126 times. Furthermore, studies have detected a total of 5 virulence factor-containing pathogenic bacteria, particularly klebsiella pneumoniae (klebsiella pneumoniae), persisting throughout storage; at the same time, pathogenic fungi such as Aspergillus, penicillium, fusarium, etc. are detected. Klebsiella pneumoniae can survive in an environment of 15-40 ℃; the mold has the survival condition of 0-40 ℃, the fusarium has the survival condition of 0-39 ℃, and most other bacteria in the kitchen waste also live by depending on the temperature and humidity environment of the kitchen waste, so that the generated solid waste is dried by the dryer, bacteria in the solid waste can be effectively eliminated, and the problem that the bacteria are bred to harm human health along with the storage time of the kitchen waste is solved.
