Abstract
The invention provides a small-size kitchen garbage fermentation device, and belongs to the field of waste recycling. The device includes a feeding system, an aerobic composting system, an anaerobic fermentation system and a deodorization system; the aerobic composting system contains six stack retting troughs which are connected to form a ring shape and wrap an anaerobic fermentation tank in the center of the device. When one stack retting trough is full of kitchen garbage, the stack retting trough is rotated to another hollow trough for bearing the kitchen garbage from the feeding system. Specific positions of the annular stack retting troughs are provided with spraying and ventilation devices for ensuring effective implementation of composting. The kitchen garbage subjected to stack retting enters the anaerobic fermentation tank for methane production fermentation. Biogas produced by the fermentation tank can be used as household fuel gas after being collected with a biogas bag. Biogas slurry and biogas residues produced by the fermentation tank are discharged into a septic tank. The device has the advantages of simple structure, small environmental pollution, waste recycling utilization and the like, and is especially suitable for treatment of kitchen garbage produced by families or residential districts.
