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。
With the corn stalk as material, a simulation test was conducted to study the effects of C/N adjustment on methane production. The results indicated that the accumulative methane production, the daily mean methane production during steady methane producing period and the carbon conversion rate were all the maximum in the N1 treatment with C/N level of 27.0. With the decline of the C/N level, the beginning time of methane production delayed, the methane producing period shortened, the accumulative methane production decreased and the carbon conversion rate declined too.
