The invention not only optimizes the environmental sanitation of residents, reduces the odor of kitchen waste in the air, reduces the possibility of cockroaches and bacteria breeding, improves the environmental sanitation working environment and reduces the pollution caused by scattered garbage. The working mode of the kitchen garbage truck in Licheng, Hubei Province is to slowly transport the bottled "swill" through the conveyor belt of the truck and pour it into the compartment at the top of the truck (the compartment can be divided into compartments and tanks). The thrown garbage is squeezed by a powerful push plate, and then solid-liquid separation is carried out. The separated liquid enters the sewage tank at the bottom of the tank, and the solid waste is compressed and stored in the tank, and the volume becomes smaller. After repeated filling, it is sent to the kitchen waste resource optimization treatment plant. The whole process is automated. The classified collection and centralized treatment of kitchen waste requires not only harmless and resource-based treatment equipment in the later stage, but also special collection and transportation vehicles. Due to the characteristics of high water content and complex composition of kitchen waste, it is required that the vehicle be closed, easy to operate, safe, efficient and convenient to load and unload, and match with the later recycling equipment.
