NOVELTY - Municipal solid waste is comprehensively utilized and processed by sorting urban domestic garbage, crushing mechanically; sorting using device sorting treatment system; crushing sorted material separately; transporting plastic garbage to hot vacuum forming machine for vacuum compression molding; transporting biodegradable powder to a anaerobic fermentation tank; adding a catalyst; adding acid-alkali neutralizing solution; and absorbing the acidic substance in the marsh gas and dissolved in ammonia gas to convert to water.    USE - Method of comprehensively utilizing and processing a municipal solid waste (claimed).    ADVANTAGE - The method is low cost and environment-friendly.    DETAILED DESCRIPTION - Municipal solid waste is comprehensively utilized and processed by:    (A) sorting urban domestic garbage, crushing mechanically, and sorting using device sorting treatment system:    (B) crushing sorted material separately, transporting plastic garbage to hot vacuum forming machine for vacuum compression molding;    (C) transporting biodegradable powder to a anaerobic fermentation tank, adding a catalyst, adding acid-alkali neutralizing solution, and absorbing the acidic substance in the marsh gas and dissolved in ammonia gas to convert to water;    (D) purifying the marsh gas as fuel gas, subjecting to secondary dehydration and compression processing to absorb absorption solution having a pH of 8 and ammonia gas, heating at 60-70 degrees C using steam, absorbing generated carbon dioxide gas and purifying, and utilizing in greenhouse vegetable planting; and    (E) preparing biogas slurry surplus of marsh biochemical treatment by aerobic activation using pulverized coal ash as adsorbent, adding marsh slag, mixing, and adding inorganic nitrogen containing fertilizer, phosphorus containing fertilizer and potassium containing fertilizer and organic fertilizer.    DESCRIPTION OF DRAWING(S) - The drawing is a flow chart of a method of comprehensively utilizing and processing a municipal solid waste. (Drawing includes non-English language text).
