| 摘要 |
The present invention relates to an anaerobic digestion apparatus, comprising: a hydrolysis storage tank for storing material to be treated; a methane fermentation tank for receiving the material to be treated from the hydrolysis storage tank and performing methane fermentation; a methane fermentation tank discharge water storage tank for storing water discharged from the methane fermentation tank; a microbe-concentrating device for receiving discharged water from the methane fermentation tank discharge water storage tank, and concentrating anaerobic microbes contained in the discharged water; a stabilizer tank for receiving liquid concentrated in the microbe-concentrating device, and stabilizing the conditions of the microbes contained in the concentrated liquid; and a buffer tank for receiving stabilized liquid containing microbes stabilized by the stabilizer tank, performing secondary stabilization, and then supplying the stabilized material to the methane fermentation tank. According to the present invention, the overall efficiency of an anaerobic digestion process can be improved, and the overall operating and maintenance costs of the apparatus can be reduced. |
