为研究稻壳类酒糟的产沼气潜力及特性,以其为原料,在恒温30℃条件下,分别用实验室正常沼气发酵后的混合厌氧活性污泥和秸秆半连续干发酵后的发酵残留物作为接种物进行厌氧消化.结果表明:以混合厌氧活性污泥为接种物的TS产气率和VS产气率分别是369 mL/g·TS和424mL/g·VS,以秸秆发酵残留物为接种物的TS产气率和VS产气率分别是468 mL/g·TS和538 mL/g·VS.
In order to study the potential and characteristics of biogas produced from rice husk stillage, using it as raw material, the fermentation residue after semi-continuous dry fermentation of mixed anaerobic activated sludge and straw after normal laboratory biogas fermentation were respectively heated at 30 ℃. Were used as inoculum for anaerobic digestion.The results showed that TS production rate and VS production rate were 369 mL / g · TS and 424 mL / g · VS, respectively, for inoculation with mixed anaerobic activated sludge The TS production rate and VS production rate of the inoculum were 468 mL / g TS and 538 mL / g VS, respectively.
