<p><P>PROBLEM TO BE SOLVED: To provide a methane fermentation treatment apparatus which can be effectively agitated by gas even when gas generation is comparatively a little. <P>SOLUTION: This apparatus is provided with a methane fermentation tank 1 having an outlet 2 formed at an upper part and an inlet formed at a lower part, and a storage tank 4 communicating with the inlet 2 and the outlet 3 arranged at higher position than the position of the inlet 3. An outlet valve 8 arranged between the outlet 2 and the storage tank 4 is made to open and an inlet valve 9 arranged between the inlet 3 and the storage tank 4 is made to close, at the time of storage by which liquid in the methane fermentation tank 1 is pushed out into the storage tank 4 via the outlet 2 by gas-pressure in the methane fermentation tank 1. Meanwhile, the outlet valve 8 is made to close and the inlet valve 9 is made to open, at the time of agitation by which the liquid in the storage tank 4 falls with gravity and flows into the methane fermentation tank 1 via the inlet 3. <P>COPYRIGHT: (C)2004,JPO</p> |
