NOVELTY - Kitchen garbage processing comprises screening and crushing the kitchen garbage, and crushing separated organic matter to fine particles to obtain a mixed material; carrying out wet thermal hydrolysis; carrying out solid-liquid separation; carrying out hydrolysis acidification; pre-processing by adding microbial composite fungicide, and fermenting at 37 degrees C for 5 days; and placing the fermentation product and the wastewater in an anaerobic fermentation reaction device, inoculating microbe composite microbial inoculum, and carrying out producing marsh gas fermentation.    USE - Method for kitchen garbage processing (claimed).    ADVANTAGE - The microorganism compound bacterial agent solves the problem that the kitchen waste with easy corrosion and high salt and high oil, and the smell in the biological treatment process. It improves anaerobic digestion marsh gas producing efficiency.    DETAILED DESCRIPTION - Kitchen garbage processing comprises:    (A) screening and crushing the kitchen garbage, classifying organic matter and inorganic matter, removing metal, plastic, and glass, and crushing the separated organic matter to fine particles to obtain a mixed material;    (B) carrying out wet thermal hydrolysis to obtain solid, wastewater, and grease mixture;    (C) carrying out solid-liquid separation of the mixture by filtering by centrifugation of wet heat treatment;    (D) recycling grease and wastewater;    (E) carrying out hydrolysis acidification to obtain a base material;    (F) pre-processing the base material by adding microbial composite fungicide, and fermenting at 37 degrees C for 5 days to obtain the fermentation product, and    (G) placing the fermentation product and the wastewater in an anaerobic fermentation reaction device, inoculating microbe composite microbial inoculum, mixing the fermentation microbial inoculum, where the mass ratio of the inoculating amount is 6-10%, for 7 days/period, at 37 degrees C and a pH of 6. 8-7.5, and carrying out producing marsh gas fermentation.    An INDEPENDENT CLAIM is included for an anaerobic fermentation reaction device.
