Abstract:
     The present invention relates to a methane-generating pit, a device treating anaerobically organic material to generate methane. The filtered raw material flows through the middle and the bottom of feeding inlet into the annular fermenting area and the central refermented area of main fermenting pit, and it is anaerobically digested in fermenting pit and ferermented in gas sump. Methane generated is led out from above the main fermenting pit and the gas sump. By means of stereo material distribution, twice fermentation and central dreg-extracting and shell-crushing device, the said methane pit can realize continuous fermentation.
