Abstract

PROVIDED IS A METHANE FERMENTATION METHOD AND A METHANE FERMENTATION APPARATUS, CAPABLE OF KEEPING A HIGH DECOMPOSITION RATIO WITH GOOD TIME EFFICIENCY EVEN WITHOUT A COMPLICATED APPARATUS CONFIGURATION. METHANE FERMENTATION IS PERFORMED USING A METHANE FERMENTATION APPARATUS THAT INCLUDES A FIRST SLUDGE CONCENTRATION MEASURING UNIT (10) FOR MEASURING A SLUDGE CONCENTRATION IN THE FERMENTATION LIQUID IN A METHANE FERMENTATION TANK (2), A SECOND SLUDGE CONCENTRATION MEASURING UNIT (20) FOR MEASURING A SLUDGE CONCENTRATION IN A PREDETERMINED PORTION OF A SLUDGE SEDIMENTATION LIQUID FORMED WITH A GRAVITY SEDIMENTATION UNIT (3), AND A CONTROL DEVICE (100) FOR COMPARING THE SLUDGE CONCENTRATION MEASURED WITH THE FIRST SLUDGE CONCENTRATION MEASURING UNIT (10) WITH THE SLUDGE CONCENTRATION MEASURED WITH THE SECOND SLUDGE CONCENTRATION MEASURING UNIT (20), AND CONTROLLING AN AMOUNT OF THE LIQUID SO THAT THE SLUDGE CONCENTRATION OF THE LIQUID RETURNED TO THE METHANE FERMENTATION TANK (2) THROUGH A RETURN LINE (L2) IS HIGHER THAN THE SLUDGE CONCENTRATION OF THE FERMENTATION LIQUID IN THE METHANE FERMENTATION TANK (2), AND THE SLUDGE CONCENTRATION OF THE LIQUID DISCHARGED THROUGH A DISCHARGE LINE (L6) IS LOWER THAN THE SLUDGE CONCENTRATION OF THE FERMENTATION LIQUID IN THE METHANE FERMENTATION TANK (2).
