| 摘 要： | 为解决玉米秸秆结构致密导致秸秆发酵难于直接降解的问题,首先分别采用0.2%、0.4%、0.6%、0.8%的HCl溶液对其进行预处理,以厌氧活性污泥为接种物进行中温(38℃)发酵产氢试验。结果表明,玉米秸秆的累积产氢量和产氢速率随着盐酸质量分数的增大先增加后降低,0.6%HCl处理效果最佳,单位累积产氢量和产氢速率分别为87.90 m L/g和3.05 m L/(g·h)。再以0.6%HCl溶液预处理的玉米秸秆为底物进行发酵产氢的单因素和正交试验,研究了秸秆粒径、底物浓度、初始p H值对玉米秸秆厌氧发酵产氢过程的影响。结果表明:玉米秸秆粒径越小越利于发酵产氢;适度增加底物浓度可增加产氢量;适宜的发酵初始p H值有利于产氢细菌的生长繁殖;得到较佳的工艺参数组合为秸秆粒径150μm、底物浓度15 g/L、初始p H值为7,此时累积产氢量为112.87 m L/g。
