Description
Technical Field

Background
The kitchen waste is complex in components, mainly contains organic substances such as starch, dietary fiber and animal fat, is high in water content, is easy to decay and generates offensive odor, and therefore is difficult to treat. According to the characteristics of the kitchen waste, the necessary pretreatment and then biodegradation treatment (i.e. biochemical treatment) are good treatment modes, the biochemical treatment has two modes of aerobic fermentation and anaerobic fermentation, the aerobic fermentation can generally produce organic fertilizer, and the anaerobic fermentation can generally produce methane. For centralized large-scale kitchen waste treatment, anaerobic fermentation is adopted, and the generated biogas can be further recycled. Because the sources of the kitchen waste are dispersed, higher transportation cost is inevitably brought to centralized treatment, and secondary spilling in the transportation process is caused, so that distributed on-site treatment is a better choice sometimes. Distributed processing generally arranges processing stations near the source of kitchen waste and is located in areas with dense personnel, so that waste processing efficiency is high, energy consumption is low, and safety and reliability are required; secondly, the floor area is required to be small, and no secondary pollution is caused; thirdly, as the operators of the common stations are few, the treatment process is simple in process and convenient to operate.

And as the biochemical treatment time is short (generally less than 72 hours), the water content in the kitchen waste cannot be effectively reduced, and simultaneously viruses, pathogenic bacteria and pathogenic microorganisms which may be generated during the storage period of the kitchen waste cannot be well killed, so that harmful substances still exist after the kitchen waste is treated.
