<p><P>PROBLEM TO BE SOLVED: To stir and transfer a fermentation treatment object liquid with no power by utilizing biogas generated by fermentation in the technology of treating organic components contained in the fermentation treatment object liquid by the fermentation. <P>SOLUTION: The fermentation treatment of the fermentation treatment object liquid containing the organic components is performed in a plurality of fermentation tanks 1, 2 whose lower parts are communicated with each other. By the pressure P<SB>1</SB>of the biogas generated in the fermentation tank 1 on the upstream side, the fermentation treatment object liquid L<SB>1</SB>is transferred from the fermentation tank 1 on the upstream side to the fermentation tank 2 on the downstream side. Also, the fermentation treatment object liquid L<SB>2</SB>in the fermentation tank 2 on the downstream side is made to overflow and transferred out of a system. By opening the pressure P<SB>1</SB>of the biogas stored in the fermentation tank 1 on the upstream side, a part of the fermentation treatment object liquid L<SB>2</SB>in the fermentation tank 2 on the downstream side is made to flow back to the fermentation tank 1 on the upstream side. Thus, the fermentation treatment object liquid is stirred and transferred with no power. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
