PRODUCING MOTHOD OF HYDROGEN GAS USING ANAEROBIC MICROORGANISM COMPLEX

摘要

A method for producing hydrogen gas by using the anaerobic microorganism complex is provided to improve production speed of hydrogen gas and perform the production of hydrogen gas at all hours. The method for producing hydrogen gas comprises the steps of: collecting the concentrated sewage sludge produced from the precipitation tank in a sewage disposal plant; treating the concentrated sewage sludge with heat to concentrate hydrogen-producing microorganisms; adding the concentrated hydrogen-producing microorganisms into a substrate; and producing hydrogen by using anaerobic fermentation processes, wherein the heat treatment temperature is 80-100 deg. C; the heat treatment is performed at 85-95 deg. C for 10-30 minutes just one time; and the substrate is sewage produced from tofu(bean-curd) production.
