With the development of economy and the progress of society, the resource treatment of kitchen waste becomes a difficult problem. The treatment of the kitchen waste by utilizing a recycling treatment technology can effectively prevent the problems of food safety, environmental pollution and the like, can produce various renewable energy sources such as biodiesel, fertilizers and the like, and finally realizes the purposes of reduction, harmlessness and recycling.
At present, existing kitchen waste on-site treatment equipment on the market generally has the current situations of large capital investment, large occupied area, large equipment power consumption, high operation cost and the like, and has various forms and different emphasis points, and a product does not completely cover the whole process of comprehensive treatment of organic waste. That is, there is no product which can fully utilize regional resources and realize the resource treatment of multisource organic wastes facing to regional differences and characteristics, and only focuses on the single link of kitchen waste treatment.
The treatment technology of the equipment on the market is mainly suitable for the environmental and geographic characteristics of the south, and the process flow and the resource treatment method of the equipment are not set in combination with the characteristics of the northwest area, particularly the suburb farming, pasturing and tourism area. For example, in northwest areas, the sunshine is sufficient in spring and summer, the climate is appropriate (different from summer in south, hot summer and no trip can be realized), the people flow is large in travel busy seasons, and the treatment capacity of kitchen waste is in a high valley situation; in autumn and winter, the sunshine is insufficient, the air temperature is reduced in a middle season (different from southern autumn, which is the best travel season), the people flow rate is low in travel and slack season, and the treatment capacity of the kitchen waste is in a low-valley state. According to the characteristics, single equipment is installed in the farming, pasturing and touring area, so that the power consumption is high, the operation cost is high, the equipment resource waste is also caused, and the equipment does not have buffer intervals when dealing with different periods of high and low valleys.
