NOVELTY - A method for two-phase hydrogen producing methane coupling reaction to process the degraded organic waste, comprises: (1) stirring and mixing the degraded organic wastes; (2) easily degradable organic microaerobic acidification; (3) acidifying connected with gas purifying; (4) hydrogen methanation of the purified gas; and (5) recycling digestive juice.    USE - The method is useful for two-phase hydrogen producing methane coupling reaction to process the degraded organic waste (claimed).    ADVANTAGE - The method has high processing efficiency, high gas yield, short production period, and it can realize the continuous stable gas, and no waste water discharge.    DETAILED DESCRIPTION - A method for two-phase hydrogen producing methane coupling reaction to process the degraded organic waste, comprises: (1) stirring and mixing the degraded organic wastes: the organic waste are mixed by uniformly stirring the heterogeneous organic wastes into homogeneous slurry, which effectively improves the biodegradability, reduces the difficulty of subsequent process; (2) easily degradable organic microaerobic acidification: using microaerobic technology carrying out acidification reaction to organic matter, to strengthen the whole hydrolysis acidification process and improves the processing capability of the part difficult to degrade in the waste, the solid material with high efficiency into soluble chemical oxygen demand (COD); (3) acidifying connected with gas purifying: the acidification phase product gas mainly hydrogen (H2) and carbon dioxide (CO2) mixed gas by pressure swing adsorption decarburization device, and then the purified gas into the methane phase reactor; (4) hydrogen methanation of the purified gas into the high efficient reactor, reduction reaction under the action of methane bacteria generating methane, increase burning first system wide; and (5) recycling digestive juice in the discharging to the acidification reactor of methane reactor to promote the acidification pre-treatment.
