Processing method and processing system for kitchen garbage resourcilization

Abstract

The invention relates to a processing method and a processing system for kitchen garbage resourcilization. The processing method comprises waterpower decomposition, fragmentation, sorting, dehydration, crushing, anaerobic fermentation and oil-water separation; the processing system comprises a feeding device, a waterpower conveying decomposition tank, a fragmentation preselection apparatus, a dehydration crushing apparatus, an anaerobic fermentation mixing apparatus and an oil-water separation apparatus. The method and system provided in the invention adopt sorting by using water. Advanced treatments of sorting to remove impurity, fragmentation, dehydration, desalination, oil removing and the like are automatically carried out to substances of different properties in the kitchen garbage by using water as a carrier combining with mechanization equipment, according to dissolvability and different proportion of the substances; organic substances separated from the kitchen garbage are fermented and prepared into organic fertilizers; and grease in separated oil-contained sewage is recycled by oil-water separating. The method and the system in the invention thoroughly remove substances of oil, salinity, soy sauce, vinegar and the like in the kit garbage that against fermentation composting. The method and the system have the characteristics of high removal rate of salinity and grease, high dehydration efficiency, good automatic sorting effect, realization of resource regeneration and no secondary pollution.

Description

technical field [0001] The invention relates to a kitchen waste treatment technology, in particular to a kitchen waste treatment method and a treatment system thereof. Background technique [0002] Existing kitchen waste is mainly composed of food waste such as leftovers, as well as other food waste such as plastic, bones, shells, stones, chopsticks, glass, paper, metal, wood, etc. About 80% of the waste, if directly discarded or treated as general urban waste, will not only pollute the environment and increase the amount of urban waste to be disposed of, but also cause waste of discarded food therein. At present, the treatment of food waste generally adopts incineration, landfill, feed and fertilizer methods. Among them, the incineration method is only suitable for combustible waste with considerable calorific value. Due to the high water content of food waste, incineration Treatment by this method will increase the consumption of incineration fuel, increase the cost of tr...

Problems solved by technology

[0003] The purpose of the present invention is to provide a salt and grease removal solution for the above-mentioned deficiencies such as high salt content, incomplete oil removal, low dehydration efficiency, high labor intensity of manual sorting, and environmental pollution in the existing food waste recycling process. High efficiency, high dehydration efficiency, good automatic sorting effect, and all organic matter, plastics, oils, etc. can be reused, resource regeneration is realized, and there is no secondary pollution. The food waste resource treatment method and its treatment system
