BIO GAS GENERATOR

摘要

PROBLEM TO BE SOLVED: To decrease the BOD in an organic waste water and to generate hydrogen and methane. SOLUTION: The organic waste water is introduced via piping 5 into a bioreactor 1 internally housed with facultative anaerobes which are one kind of hydrogen-evoluting bacteria. Hydrogen is generated by the effect of the hydrogen-evoluting bacteria and organic acid which is the substrate of methane is formed. The liquid containing the organic acid is introduced via piping 9 into a bioreactor 3 internally housed with the methane bacteria. The organic acid is decomposed by the effect of the methane bacteria, by which the methane is generated and the BOD is decreased. The liquid is thereafter discharged from piping 15.
