| 摘 要： | 实验主要研究了NaOH预处理对玉米秸秆厌氧消化产气量和产气效率的影响。采用质量分数分别为1.0%、2.5%、5.0%和7.5%NaOH溶液对玉米秸秆进行24 h浸泡和未浸泡等预处理,测定其厌氧消化过程中各指标的变化。结果表明,经质量分数为5.0%NaOH浸泡24 h后,玉米秸秆木质素降解率最大,为38.67%;厌氧发酵累积产气量为226.75L/kg VS,与未经碱处理实验组相比提高了38.5%。该结果提示,5.0%NaOH溶液浸泡24 h后可使玉米秸秆厌氧消化的产气量和产气效率显著提高。 |

| Abstract: | The present paper focused on the effect of NaOH pretreatment on anaerobic digestion (AD) of corn stover. NaOH solution with the concentrations of 1.0%, 2.5%, 5.0%, 7.5% (M/V) was used for pretreating corn stover with 24-soaked or no-soaked status, and the biogas production effeciency was determined during the AD process. The obtained data showed that lignin of corn stover was degraded up to 38.54% by 5.0% NaOH pretreatment for 24 h. The total gas yield was 226.75 L/kg VS, which was 38.54% higher than the group without NaOH pretreatment. All the results indicated that the pretreatment of corn stover by 5.0% NaOH for 24 h was preferred for further study due to its significant improvement of biogas prodution and efficiency of anaerobic digestion. |
