NOVELTY - Producing fruit and vegetable garbage anaerobic digestion marsh gas includes carrying out fruit and vegetable waste extrusion; strengthening acidification pre-process of the solid residue, carrying out micro-aerobic hydrolysis acidification reaction; collecting hydrolysis acidification liquid, extruding and separating the primary hydrolysis acidification liquid product; inoculating and carrying out high-efficiency methane production process reaction, and producing methane; and promoting the solid residue of hydrolysis acidification process.    USE - Method for producing fruit and vegetable garbage anaerobic digestion marsh gas (claimed).    ADVANTAGE - The method has high processing rate, high gas yield, short production period and no wastewater discharge, and can realize continuous stable gas.    DETAILED DESCRIPTION - Producing fruit and vegetable garbage anaerobic digestion marsh gas comprises: (A) placing the fruit and vegetable waste in the primary hydrolysis acidification pool for 1-2 days at 30-35 degrees C for a short period of time hydrolysis acidification reaction; (B) carrying out fruit and vegetable waste extrusion in primary hydrolysis acidification fruit and vegetable waste into screw extrusion system to carry out dehydration, solid-liquid separation, and compression volume reduction; (C) strengthening acidification pre-process of the solid residue, adding water concentration of organic sludge of the sewage treatment plant at 25 g/L as inoculating microorganism, and dissolved oxygen concentration by controlling the flow rate of aeration at 0.2-0.5 mg/L in a micro-aerobic hydrolysis acidification environment, carrying out micro-aerobic hydrolysis acidification reaction to make the cellulose in the solid material composition obtained degradation, the solid substance into soluble COD and converted into low carbon chain fatty acid; (D) collecting hydrolysis acidification liquid, adjusting process is provided with a percolate collecting box, extruding and separating the primary hydrolysis acidification liquid product and strengthening acidification pretreatment reactor of the filtrate, mixing and making the pH to 7.5-8.5; (E) pumping the mixing hydrolysis acidification liquid to the methanation reactor, inoculating the sewage treatment plant sludge, carrying out methane production process reaction, and producing methane; and (F) in the liquid flow system in the methanation reactor, pumping the digestion liquid into the reinforced hydrolysis acidification reactor, and further promoting the solid residue of hydrolysis acidification process.
