| 摘要 |
The present invention relates to an anaerobic digestion system for using aerobic fermented heat as heating energy and, more specifically, to an anaerobic digestion system for using aerobic fermented heat as heating energy, capable of separating various organic wastes into a solid and a high-concentration liquid in a convenient manner. The system comprises: crushing and mixing the organic wastes by using a pretreatment device (100), and filtering the same; and liquid-solid separating the same into the solid and the high-concentration liquid. The high-concentration liquid enables to produce methane gas by supplying the same to an anaerobic digestion tank (300) formed to cover the outer surface with an anaerobic fermented tank (200), and anaerobically treating the same. The solid enables to increase a generation rate of methane gas by supplying the same to the anaerobic fermented tank (200), and promoting the growth of anaerobic microorganisms inserted in the anaerobic digestion tank (300). |
