Description

Kitchen waste microbial treatment system

Technical Field

The utility model relates to a meal kitchen waste disposal technical field, concretely relates to meal kitchen waste microbiological treatment system.

Background

The kitchen waste refers to food leftovers discarded in the food processing process, food residues after eating and drinking, and untreated sewage generated in the processes of cleaning food, washing tableware and the like. The main components of the food comprise pericarp broken bones, meal broken grains, insoluble protein, cellulose and starch-state insoluble organic matters, and the components of the food are very complex according to different meals. Because the kitchen waste contains rich nutrient substances, if the kitchen waste is directly discharged to the nature without being treated, the kitchen waste is decayed in a short time under the action of proper temperature and bacteria, so that the kitchen waste not only pollutes the surrounding environment, breeds mosquitoes and flies, and occupies a large amount of land, but also causes a large amount of waste of resources. The characteristics that domestic kitchen discarded object appears at present are specifically shown as: (1) the kitchen waste oil and salt content is high, the kitchen waste oil and salt content in China is generally higher than that in European and American areas, the kitchen waste oil and salt content in China is about 5% -8% on average, the treatment difficulty of the traditional treatment process is high, for example, the high-temperature aerobic composting treatment process and the anaerobic fermentation process are high, the high-oil and high-salt content in the kitchen waste are very unfavorable for the growth of microorganisms, and the effects of the high-temperature aerobic composting treatment process and the anaerobic fermentation process are restricted; (2) the water content is high, and the water accounts for 80% -90% of the total weight of the kitchen waste, which brings problems to the collection and transportation of the kitchen waste, and if the kitchen waste is mixed with common household garbage, the water content of the common garbage is also improved, the heat value is reduced, and certain difficulty is generated in the application of the garbage incineration technology; (3) the organic matter content is high, and the organic matter is easy to rot and deteriorate under the high-temperature condition, generates odor, and threatens the health of residents living near a collection place.

Based on the research and development of the kitchen waste treatment equipment, the kitchen waste is effectively degraded and comprehensively treated, and the reduction and resource utilization of the kitchen waste are realized, so that the kitchen waste treatment equipment has very important significance. The mainstream treatment mode of the existing kitchen waste comprises the following steps: composting, hydrogen production by fermentation, direct landfill, incineration and the like. The composting method and the fermentation hydrogen production method have the problems of long period, low efficiency, low resource degree and the like, and the direct landfill method and the incineration method for treating the kitchen waste cause environmental pollution and do not accord with the concepts of circular economy and sustainable development. Based on the defects of the existing kitchen waste treatment method, the environment-friendly pollution-free efficient kitchen waste treatment system is provided, and has important significance for protecting the environment, saving resources, promoting economic development and the like.
