| 中文摘要 |
| 以加热预处理的厌氧活性污泥为接种物，以秸秆（稻草、麦杆）为发酵底物进行微生物产氢实验，研究了不同秸秆粒径、纤维素酶用量、预处理方法、发酵液pH值对秸秆发酵产氢速率以及产氢气量的影响.其中颗粒粒径为170 μm的稻草经过NaOH预处理，按照底物与纤维素酶用量1∶1的比例酶解，进而发酵产氢的单位总产氢量为90.5 mL/g，最大单位产氢速率为0.58 mL/(h·g). |
| 英文摘要 |
| Biohydrogen production from straw by anaerobic fermentation of digested sludge was studied. The influence of the main parameters such as particle size，the ratio of substrate to cellulase，pretreatment method and pH on the straw fermentation was investigated．With NaOH pretreatment, the rice straw with average particle size of 170 μm was fermented after hydrolyzed by cellulase with the ratio of substrate to cellulase as 1∶1. And its maximal velocity and the total volume of hydrogen are respectively 0.58 mL/(h·g) and 90.5 mL/g. |
