Method for pretreating urban and rural domestic refuse by means of mechanical-biological method

The invention discloses a method for pretreating urban and rural domestic refuse by means of a mechanical-biological method, and relates to the technical field of environmental protection. According to the technological process, the method is prominently characterized in that primary crushing and mechanical retransfer are adopted, and then a pore texture beneficial for bio-drying is formed; and free transfer of moisture of domestic refuse is achieved in the bio-drying process, and then water on the surface of the domestic refuse is removed in a mechanical squeezing manner, and therefore effective solid-liquid separation of the domestic refuse is achieved. Products produced through mechanical-biological method pretreatment are suitable for cement kiln collaborative incineration disposal or grate furnace incineration disposal. According to the method for pretreating the urban and rural domestic refuse by means of the mechanical-biological method, by means of organic linking with an incineration system, harmless
