Title: METHANE FERMENTATION TREATMENT SYSTEM AND METHANE FERMENTATION TREATMENT METHOD
Abstract:
Provided are a methane fermentation treatment system and a methane fermentation treatment method in which organic waste water containing solid organic matter is subjected to methane fermentation so as to enable increasing of the amount of gas to be recovered. The methane fermentation treatment system 1a, 1b, 1c, 1d according to the present invention carries out methane fermentation by treating organic waste water containing solid organic matter using a methane fermentation microbial community, and is provided with: an endless water channel 11 through which the organic waste water is circulated; and a plurality of fixed beds 12 on which the methane fermentation microbial community is accumulated, wherein the distance between adjacent fixed beds 12 is 100-3000 mm. It is preferable to install the fixed beds 12 such that the lower ends thereof are situated at a height of at least 100 mm from the bottom of the endless water channel 11. Further, it is preferable for the inside of the endless water channel 11 to be provided with a redispersion device 14 for redispersing solid organic matter floating in the organic waste water.
