NOVELTY - An urban household waste processing method involves sorting waste raw material sent to sorting machine, and separating organic matter and a non-yeast inorganic substance. The collected organic matter is sent to a crusher to be crushed. Fermented organic medium is crushed to obtain a fermented product. Enzymolysis is carried out on the fermented product by filtering and separating biogas liquid and biogas residue that is used to dehydrate to produce higher organic fertilizer according to normal process.    USE - Method for processing urban household waste.    ADVANTAGE - The method enables processing urban household waste with improved efficiency, marsh gas fermentation quality, recycling effect, environmental friendly effect, better social benefit and production efficiency.    DETAILED DESCRIPTION - An urban household waste processing method involves sorting waste raw material sent to a sorting machine at speed of 12 r/min, and separating organic matter and a non-yeast inorganic substance. The collected organic matter is sent to a crusher to be crushed, where granularity of the organic matter is controlled at 500-1000 meshes. The fermented organic medium is crushed to obtain a fermented product, and fermentation time is controlled at 35-55 degrees C for 38-60 hours to obtain a dry clinker. The dry clinker is selected to water purifying, and waste foam plastic is washed. The purified water is sent to a marsh gas fermentation tank to ferment for 24-36 hours, and fermenting temperature is controlled at 45-60 degrees C, where pH value is 7-7.5. Enzymolysis is carried out to the fermented product by filtering and separating biogas liquid and biogas residue, where a biogas slurry conveyer is used for circulating fermentation to the fermentation tank, and the biogas residue is used for dehydration to obtain higher organic fertilizer.
