Hydrogen production from dark fermentation of high-protein material under anaerobic condition

摘要

Heat-treating the anaerobic digester sludge in the case of producing hydrogen using anaerobic digestion of high-protein waste; Preparing a mixture of the heat-treated anaerobic digester sludge and high-protein waste; And a step of culturing the mixed solution in a dark place to ferment an anaerobic cancer. The present invention also provides a method for producing hydrogen by anaerobic fermentation of high-protein waste. It is an optimum hydrogen production method to cultivate the mixture at a mixing ratio of 48 to 52 DEG C such that the F / M ratio is 6 and the pH is 8.2. According to the present method, high-efficiency hydrogen production can be achieved through fermentation of anaerobic digestion of high-protein waste, which is known to have low hydrogen production efficiency.
