NOVELTY - Treating high hydrous organic waste comprises sorting kitchen waste followed by crushing, homogenizing, pulping and separating, acidifying the waste, processing agricultural products, pressing livestock excrement to precipitate sand by solid-phase grinding and pulping and squeezing water directly in the solid phase crushed pulp and acidifying to prepare anaerobic raw material, pumping anaerobic raw material into an anaerobic tank and performing anaerobic fermentation, stirring gas, filter pressing marsh gas into solid phase to form organic fertilizer, and collecting water phase for treating.    USE - The method is useful for treating high hydrous organic waste.    ADVANTAGE - The method allows simple treatment of high hydrous organic waste with less labor intensive in a convenient manner, and improves the anaerobic fermentation production rate and sludge load rate of the biogas residue generation.    DETAILED DESCRIPTION - Treating high hydrous organic waste comprises: (1) sorting kitchen waste followed by crushing, homogenizing, pulping and separating, and acidifying the waste to adjust the pH of 3.5-4, where the chemical oxygen demand content is 80-120 kg/m3, total solid content is 6-8% and oil-containing rate is 2%; (2) processing agricultural products; (3) pressing livestock excrement to precipitate sand by solid-phase grinding and pulping, and directly squeezing water in the solid phase crushed pulp and acidifying to prepare anaerobic raw material; (4) pumping anaerobic raw material into an anaerobic tank and performing anaerobic fermentation at a temperature of 52- 58 degrees C and stirring gas, where oxidation-reduction potential is -180 mV to -350 mV, and (5) filter pressing marsh gas into solid phase to form organic fertilizer, and collecting water phase for treating using discharge standard.
