DETAILED DESCRIPTION - Kitchen waste and gas fermentation processing system comprises pre-processing unit and conveying unit, which is connected to kitchen waste collecting groove, impurity screening machine, kitchen crusher, solid-liquid separating machine, sterilizing drying machine, and stirring and mixing groove. The stirring and mixing tank is connected to automatic oil-water separator, which is connected to kitchen collecting groove, impurity screening machine and solid-liquid separating machine. Pre-processing unit is connected to fermentation collecting unit, which comprises fertilizer fermentation tank, fertilizer fermenting groove and pre-mixing groove. Liquid fertilizer fermentation tank is connected to automatic oil-water separator, which is connected to biological deodorization filtering tower for collecting exhaust gas. An INDEPENDENT CLAIM is included for a method for processing kitchen waste and gas fermentation, which involves:    (A) collecting kitchen waste into kitchen waste collection tank for screening impurities;    (B) transporting kitchen waste collection tank;    (C) cleaning and crushing kitchen waste food;    (D) grinding food waste to obtain particles;    (E) drying kitchen waste particles;    (F) sterilizing dehydrated kitchen waste particles at high-temperature;    (G) mixing kitchen waste particles with microbial flora in a tank;    (H) fermenting mixture at constant temperature to obtain solid fertilizer;    (I) collecting solid fertilizer through pipe into automatic oil-water separator to remove grease and suspended solids;    (J) transferring treated wastewater into fermentation tank liquid fertilizer;    (K) fermenting mixture with microorganisms in a closed fermentation tank under aerobic or anaerobic condition to obtain liquid fertilizer; and    (L) treating gas by importing kitchen exhaust generated by biological deodorization filter tower to remove the smell of exhaust gas after discharge.
