The invention relates to a method for increasing the
hydrogen output through anaerobically digesting restaurant garbage and relates to a method for producing the
hydrogen output through anaerobically digesting the restaurant garbage, which comprises following steps: firstly, weighing according to granular
sludge: the restaurant garbage=1:0.2-0.4 part
dry weight, adding the granular
sludge and the restaurant garbage into a
bottle, filling
nitrogen or
argon, sealing, statically culturing under the temperature of 4-20DEG C, finishing
domestication when the pH value is lowered to 4.5-5.5, preserving, then, weighing according to the restaurant garbage: the granular
sludge which is domesticated well=1 part
dry weight:0.59-0.294part
dry weight, then, arranging the restaurant garbage and the granular sludge into a container, evenly mixing, filling the
nitrogen or the
argon, then, sealing, concussing and stirring under the temperature of 40-50DEG C and the speed of 100-130r / min, starting
anaerobic digestion, wherein the
hydrogen yield is 65.63mL / g VS-94.04mL / g VS, fermenting
firedamp with residual material after the hydrogen stops producing, and transforming the residual material into the
firedamp. The method of the invention has the characteristics of low
energy consumption, low cost and
high heat value net output rate, and the
hydrogen yield can reach 93mL / g restaurant garbage (dry weight) through using the method of the invention, which is increased by 20-30% compared with existing
hydrogen yield.
