NOVELTY - Producing food and domestic waste into organic fertilizer comprises feeding food waste into a separation plant, crushing, adding domestic sewage, stirring and pumping into a temporary storage tank A, subsequently crushing human excreta, livestock dead substance waste, slaughtering industry waste and vegetable based food waste and pumping into respective temporary storage tanks, pumping water treatment slag into a sedimentation tank, press filtering crushed substances and water treatment slag, burying, feeding e.g. calcium phosphate, sealing to decompose, and conveying to produce biogas.    USE - The method is useful for producing food and domestic waste into organic fertilizer (claimed).    DETAILED DESCRIPTION - Producing food and domestic waste into organic fertilizer comprises (a) feeding food waste into a separation plant, extracting organic fertilizer from the waste by a method mentioned in application number: 201110293950.4, separating the produced organic fertilizer, crushing, adding domestic sewage, stirring and pumping into a temporary storage tank A via a pump, (b) collecting human excreta from direct odorless sterile flushing-free squatting pan according to patent number ZL200910179635.1, fixing and collecting all the human waste based on patent number ZL200410034448.1, crushing, and pumping into a temporary storage tank B, (c) crushing livestock dead substance waste, and pumping into a temporary storage tank C, (d) crushing slaughtering industry waste and pumping into a temporary storage tank D, (e) crushing vegetable based food waste, and pumping into a temporary storage tank E, (f) directly pumping water treatment slag into a sedimentation tank via a pump, (g) transporting in all the tubes, and (h) press filtering to obtain pure liquid and solid fertilizer within the temporary inner storage tanks (A), (B), (C), (D) and (E) crushed substances and water treatment slag, conveying into the sedimentation tank via respective pumps, sedimentation of sand, stone, soil and impurities, burying underground via a slurry pump, taking as organic fertilizer raw material, pumping into a stirring tank, feeding 3-5% calcium phosphate or gypsum per hundred pounds, adding 5-6 units green alum, pumping into a large underground storage tank via a pump, sealing to decompose for decomposition of organic fertilizer, feeding into a detection station, conveying for standardization process, supplementing with chemical fertilizer based on soil and crops fertilizer condition of each surrounding cities, conveying the organic fertilizer to soil, farms and underground storage tank to produce biogas, where the biogas is conveyed to the user from the biogas station. The waste includes direct waste having waste paper, rubber, metal, plastic, glass, food and human excreta, and indirect waste having livestock dead substance, slaughtering industry waste, regeneration waste, water treatment slag, and landfill and incineration wastes.
