The organic waste comprises urban kitchen waste, household kitchen waste and excrement; the food chain type hidden danger of huge pathogen transfer and diffusion is a food safety problem and a social problem because the food chain type hidden danger of the food chain type is that the food chain type hidden huge pathogen transfer and diffusion is a food safety problem, and the food chain type is a huge food chain type. A plurality of countries such as the United states, Canada, European Union and the like have enacted a plurality of laws which forbid the direct feeding of pigs by untreated kitchen waste, and China strictly controls the laws. Although the yield of the kitchen waste is huge and the influence is wide, the links of classification, collection, transportation, treatment and the like lack effective management and supervision of governments and active participation of good enterprises, so that the current situations that the resource utilization efficiency of the kitchen waste is low and the market is disordered are formed. In addition, a simple manual workshop production mode for carrying out maggots/earthworms and the like by utilizing breeding wastes such as chicken manure, pig manure and the like also exists in rural areas in China. Under the background of intensive feeding of the current animal husbandry, the production mode can not efficiently convert resources due to the roughness of the production process, wastes organic waste resources such as livestock manure and the like, can cause secondary pollution of soil, air and underground water, and can also cause the spread of livestock epidemic situation due to a non-scientific production mode. In order to effectively treat and utilize organic wastes, it is necessary to provide a method for recycling organic wastes. When the organic waste recycling treatment method in the prior art is used, the environment-friendly effect is poor, a large amount of stink and pollutants are generated, the environment is polluted greatly, the organic waste cannot be fully treated and utilized, the resource conversion rate is low, a large amount of resources are wasted, and the organic waste recycling treatment method is inconvenient to use.
