<p>PURPOSE:To prevent the product of hydrogen from being impaired and to inhibit formation of hydrogen sulfide by providing gaseous hydrogen occlusion place to an anaerobic treatment tank wherein orgaic drainage is treated by anaerobic bacteria and preferentially occluding hydrogen produced in a reaction stage. CONSTITUTION:In a treatment tank 1 wherein orgaic drainage is treated by anaerobic bacteria, gaseous hydrogen occlusion place 6 (hydrogen occlusive alloy) is provided to the arbitrary part of a gas stagnant zone 4 or a gas circulation path 5. Thereby digested gas lowered in the partial pressure of hydrogen is blown into liquid 2 to be treated in the treatment tank 1 and activity of decomposition bacteria of butyric acid and propionic acid, etc., is enhanced and activity of methane bacterial utilized for acetic acid is promoted. Furthermore both reduction of sulfate contained in sewage, industrial drainage and sludge and generation of hydrogen sulfide are inhibited and stable anaerobic treatment is performed.</p> |
