NOVELTY - A system comprises a first feeding opening, an anaerobic reactor, a solid-liquid separating machine (4), a first liquid-controlling valve (5) and a gas passage, where the anaerobic reactor comprises at least one hydrolysis reactor (1), the solid digester (2) and the liquid digester (3) digesting the first feed opening and the hydrolysis reactor, where the hydrolysis reactor is connected with the solid slacker and the liquid digester, and where the solid digester and solid-liquid separator, or the liquid digester and solid-liquid separator is connected with first liquid-controlling valve.    USE - As a system for used in waste anaerobic fermentation process (claimed); for producing biological energy gas and biogas residue; for the treatment of waste water; and for rural and urban waste containing manure, straw, farm product, domestic waste, food waste, and sludge.    ADVANTAGE - The system and method provide high efficiency in waste anaerobic fermentation process; provide improved reaction speed; and produce more biological gas.    DETAILED DESCRIPTION - A system comprises a first feeding opening, an anaerobic reactor, a solid-liquid separating machine (4), a first liquid-controlling valve (5) and a gas passage, where the anaerobic reactor comprises at least one hydrolysis reactor (1), the solid digester (2) and the liquid digester (3) digesting the first feed opening and the hydrolysis reactor, where the hydrolysis reactor is connected with the solid slacker and the liquid digester, and where the solid digester and solid-liquid separator, or the liquid digester and solid-liquid separator is connected with the first liquid-controlling valve, where the hydrolysis reactor, solid slacker and the liquid digester are connected with the collecting channel. An INDEPENDENT CLAIM is included for a waste anaerobic fermentation process, involving feeding the solid-liquid mixing material through input opening into hydrolysis reactor, followed by subjecting to anaerobic degradation under the condition of hydrolysis and acid producing bacteria; degrading the rest solid substance by pumping the solid digesting degraded degradation liquid into liquid digester; allowing gas, hydrogen, methane, carbon monoxide enter into gas channel, degrading the biodegradable solid matter into biogas residue and biogas liquid and gas methane under the effect of microorganism in the solid digester, and degrading the carbon dioxide, and degradation liquid into liquid and gas methane under the effect of microorganism in the liquid digester, separating the biogas residue and biogas slurry from the solid digester using the solid-liquid separator, where the biogas residue and biogas slurry are separated using the first liquid-controlling valve; and subjecting the solid digester uniformly into the gas passage.
