NOVELTY - Preparation of organic fertilizer using urbanized excrement sewage manure involves collecting urbanized manure pool; transporting into lagoon, adding lime powders, separating solid and liquid; standing, separating solids and liquid, placing feces on upper floor, fecal sewage in middle and fecal residue on lower floor, discharging into liquid pool; discharging fecal sewage, adding crop straw powders, remaining feces and fecal residue, stirring; delivering into fermentation tank, fermenting, packaging; and discharging manure sewage, adding food scraps, fermenting, and barreling.    USE - Method for preparing organic fertilizer using urban excrement sewage manure (claimed).    ADVANTAGE - The method utilizes waste.    DETAILED DESCRIPTION - Preparation of organic fertilizer using urbanized excrement sewage manure comprises collecting urbanized manure pool in excrement vehicle; transporting manure and sewage sludge into lagoon, adding 2-4 kg lime powders per cubic manure, stirring for 15- 30 minutes, separating solid and liquid; stirring, standing for 25-40 minutes, separating solids and liquid, placing feces on upper floor, fecal sewage in middle and fecal residue on lower floor, discharging through sewage pipes into liquid pool; discharging fecal sewage, adding crop straw powders, remaining feces and fecal residue, stirring to form semi-finished product, controlling moisture at 20-40%; delivering semi-finished product into fermentation tank, naturally fermenting for 15-25 days, packaging powdery organic fertilizer; and discharging manure sewage, adding 100-200 kg food scraps per cubic manure sewage, naturally fermenting for 7-15 days, and barreling. An INDEPENDENT CLAIM is included for preparation device comprising lagoon (1), mixing bucket (2), sewage pump (3), complement hopper (4), auxiliary material transport belt (5), transport groove (6), transmission belt (7), spiral stirring mechanism (8) and spiral transport machine (9).    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of preparation device.    Lagoon (1)    Mixing bucket (2)    Sewage pump (3)    Complement hopper (4)    Auxiliary material transport belt (5)    Transport groove (6)    Transmission belt (7)    Spiral stirring mechanism (8)    Spiral transport machine (9)
