摘要:以玉米秸秆原料为试材,研究了不同碳氮比条件对沼气产气状况的影响。结果表明,碳氮比值为
27 0的 N1 处理,累积产气量、稳定产气周期内的日平均产气量及碳转化效率等指标均达到最大值;随着碳氮
比的降低,产气开始时间延迟且产气周期缩短,累积产气量也降低,并且碳转化效率也有所下降。

Abstract W ith the corn stalk as material, a simulation test was conducted to study the effects of C /N
adjustment on methane p roduction The results indicated that the accumulative methane p roduction, the daily
mean methane p roduction during steady methane p roducing period and the carbon conversion rate were all the
maximum in the N1 treatment with C /N level of 27 0 W ith the decline of the C /N level, the beginning time
of methane p roduction delayed, the methane p roducing period shortened, the accumulative methane p roduction
decreased and the carbon conversion rate
