あった。It is a well-known fact that photosynthetic bacteria and other microorganisms have the ability to generate hydrogen gas, and there is much basic research in this direction. However, despite a large amount of basic research, it has not been successfully put into practical use because it is difficult to set the conditions for generating hydrogen gas, and the amount of hydrogen gas generated is small, making it very economical to produce. The reason was that it was not connected.

We have arrived at the invention described.

る。Further, when a liquid in which aerobic bacteria have grown in large quantities is rapidly placed under anaerobic conditions to generate hydrogen gas, if photosynthetic bacteria are allowed to coexist, the generation of hydrogen gas will further increase. It is known that photosynthetic bacteria themselves generate a small amount of hydrogen gas, but in the above case, when photosynthetic bacteria coexist, the amount of hydrogen gas generated increases even more. be. Although the details of the reason why hydrogen gas generation increases when photosynthetic bacteria coexist are not clear, the present inventors believe that self-digested aerobic bacterial cells do not serve as a substrate for photosynthetic bacteria, and for some reason, photosynthesis increases. We believe that this may improve the ability of bacteria to generate hydrogen.

This is a new finding.

した表１の通シであった。Furthermore, if the anaerobic state is maintained even after the invention in which photosynthetic bacteria are present, that is, after the generation of hydrogen gas from the liquid in the anaerobic tank has been completed, a large amount of Methane gas is generated. For example, Example 2.4.7.9 described below
In the case of and U, after generating hydrogen gas, the wastewater is transferred to the next anaerobic tank (if a first anaerobic tank and a second anaerobic tank are provided for continuous treatment), and is gently stirred for another 72 hours. Therefore, the amount of methane gas generated when placed in an anaerobic state was as shown in Table 1 below.
この際のメタン菌の液への接種はもちろん積極的に行な
ってもよいが、好気性菌体の大量増殖過程の中で自然に
混入されるメタン菌の存在で十分である。Of course, the methane bacteria may be actively inoculated into the liquid at this time, but the presence of the methane bacteria that is naturally mixed in during the mass multiplication process of aerobic bacteria is sufficient.

本発明の水素ガス発生後に、メタンガスを発生させる技
術は大変優れているといえる。The wastewater after collecting methane gas in Examples 2.4.7.9 and 11 of the present invention is purified to an EOD value of about 100 ppn, and then the normal wastewater purification process, namely sedimentation M[, The water can be sequentially transferred to an aeration tank and a settling tank to produce fresh water that can be discharged. Furthermore, the bacterial cell precipitate as a by-product can be reused as a resource. By the way, the method of generating electricity from methane gas generated by methane fermentation is a technology that has been implemented worldwide, but in this case, the waste water after methane fermentation is extremely unclean.
If left as is, contamination would occur again, so repurification was necessary. However, if the energy that has been generated is consumed again for the purification process, it will be negative from the point of view of production.
In view of the fact that the energy production technology by methane fermentation is not a very good technology, the technology of the present invention for generating methane gas after generating hydrogen gas as described above can be said to be very excellent.

The above wastewater was inoculated with the aerobic bacteria Bacillus megaterium, Azotobacter vinellandii, and Satucharomyces cerevisiae, and then a culture solution of the photosynthetic bacterium Chromatiu, which had been mass-cultured, was added to the water.
1 was added and vigorously aerated for n hours to grow a large amount of aerobic bacterial cells and photosynthetic bacteria inoculated into the wastewater. Rapidly (in 5 minutes) liquid in which aerobic cells and photosynthetic bacteria have grown
The mixture was transferred to an anaerobic tank and gently stirred under anaerobic conditions for 72 hours. During this time, the generated combustion gas accumulated above the anaerobic tank and was led to the gas storage tank and stored there.
