牛粪与蘑菇渣厌氧混合发酵产沼气研究
|
摘要
文章以牛粪和蘑菇渣为研究对象,进行了牛粪和蘑菇渣厌氧混合发酵的批次实验,并对厌氧混合发酵过程的累积甲烷产量进行了模型拟合。研究结果表明:蘑菇渣和牛粪的质量比为1∶3时,发酵系统的产甲烷效果和稳定性最好;但是,相对于单一牛粪发酵而言,混合发酵的产气量并没有表现出更多的优势;Gompertz模型更适合于牛粪和蘑菇渣厌氧混合发酵实验组累积甲烷产量的预测和分析。
This research focused on the co-digestion of dairy manure(DM) and spent mushroom substrates(a kind of agro-residues,SMS). The bath tests were conducted to evaluate the potential of biogas production. Model fitting and biodegradability analysis were carried out on the co-digestion process. The results showed that methane production and system stability met satisfactory requirement when the quality ratio of SMS to DM was 1∶3. However, the methane production of the co-digestion of DM and SMS did not show any further advantage than that of single DM. The Gompertz model was found to be suitable for the prediction and analysis of the methane production in the co-digestion experiment group.
