Study on Hydrogen Production by High Effect Hydrogen Production PSB Group with Pig Dejecta as Substrate

With PSB group and pig dejecta as substrate,the paper studied the hydrogen production amount under different.The results are as follows:The operation conditions.The results are as follows: The amount of H-2 production is directly proportional to the concentration of substrate,with a view to the industrial application,the usual point is 5 000 mg·L~(-1);the effect of temperature on H-2 photoproduction was more notable.The optimal temperature of H-2 production by the bacteria group was 30 ℃.With the increase of light intensity,H-2 production activity of bacteria group would increase accordingly.When light intensity was higher than 1 000 lx.the H-2 production activity was higher than that when light intensity was lower than 1 000 lx.When light intensity was 1 600 lx,the H-2 production quantity reached the biggest value.The fit pH value was 6.5～7.5.When pH value was 7.0,the H-2 production is the highest.In the process of H-2 production,the oxidation-reduction potential maintain250 mV.
