Method of Power Generation after Hydrogen is Produced with Piggery Wastewater

Abstract

It is a technology that produces the hydrogen gases by using only the microorganism and sunlight from the wastewater to be at a loss because of processing. And, the produced hydrogen uses the fuel cell and is used to generate electricity. Because this technology doesn't use the organic matter that becomes food, and use the organic matter included in waste, clean power generation is possible. We researched the improvement of the hydrogen gas production efficiency. The purple non-sulfur photosynthesis bacillus was purely cultured, the substrate dependency was clarified, and the best substrate dosage was decided. Moreover, it was shown that the light wave length conversion net was effective for the hydrogen gas production efficiency improvement. On the other hand, a too strong light intensity showed becoming the growth obstruction of phototropic bacteria. When the light intensity for the photosynthesis is insufficient, the light wave length conversion net can support this. On the other hand, there was an effect of easing the trouble by light when the light intensity was excessive. We were able to offer the design parameter to produce the hydrogen gases with the wastewater efficiently.
