Abstract

The invention relates to kitchen waste aerobic fermentation system and process. The aerobic fermentation system sequentially comprises a weighing and sorting device, a crusher, a cooking pot, a three-phase separation device and an oxygen-generating fermentation bin according to a treatment route. The aerobic fermentation process comprises the steps of weighing and sorting, crushing, cooking and three-phase separation; aerobic fermentation on solid residues, collection of grease and treatment of wastewater; aerobic fermentation waste gas treatment; and collection of an aerobic fermentation product as a fertilizer. According to the kitchen waste aerobic fermentation system and process, the grease precipitation amount of kitchen waste is increased, the three-phase separation effect is improved, and the requirement for follow-up treatment equipment is lowered; besides, the heat loss is greatly reduced, and a good energy-saving effect is achieved; the process flow of aerobic fermentation isperfected, so that the whole system and process are harmless, and the influence on the environment is reduced; separated grease is collected; in addition, the solid-liquid mixture fermented by the aerobic fermentation bin is used as a fertilizer, so that economic benefits can be generated, resource reutilization is maximized, and the kitchen waste treatment cost is reduced.

Description

technical field [0001] The invention relates to the field of kitchen waste treatment, in particular to an aerobic fermentation system and process for kitchen waste. Background technique [0002] Food waste generally refers to food processing waste (kitchen waste) and edible residues generated in the catering industry and residents’ lives. The main components include organic components such as protein, starch, and oil. They have high moisture content, high oil, and salt content, and are perishable. Smelly and other characteristics. Chinese cities produce no less than 60 million tons of food waste every year, and the output of food waste in large and medium-sized cities is astonishing. The problem is especially serious in cities with developed catering industries such as Chongqing, Beijing, and Guangzhou. [0003] At present, the treatment technologies of food waste mainly include anaerobic digestion, feed, food grinder, aerobic composting, and small biochemical on-site treat...
