Inner loop formula anaerobism bioreactor

The utility model discloses an inner loop formula anaerobism bioreactor, waste water through the feed inlet get into behind the reacting chamber with the reacting chamber in mud mix and carried out the anaerobism by the microorganism in the mud and decompose and produce marsh gas, the marsh gas that has mix with mud particle and liquid separates through one-level three-phase separator and second grade three-phase separator, then again in proper order by mud-water separation jar and vapour and liquid separator separation, the content of liquid phase and solid phase impurity has been reduced in the marsh gas of final acquisition by a wide margin, the reacting chamber mesocycle use that can flow back again of solid impurity and the water isolated at this in-process simultaneously, the water content of mud keeps helping the mixture of mud, water and microorganism in certain level in messenger's reacting chamber, improve its throughput and marsh gas output simultaneously.
