To solve the problem of the compact structure of maize straw leads to difficulty in direct degradation of the straw stalk fermentation, first with 0.2%, 0.4%, 0.6% and 0.4% respectively of HCl solution on the pretreatment, anaerobic activated sludge as inocula on wen (38 ℃) fermentation hydrogen production test. Results show that the accumulation of corn straw to produce hydrogen and the hydrogen production rate after the first increases with the increase of mass fraction of hydrochloric acid, 0.6% HCl treatment effect is best, unit cumulative amount of hydrogen production and hydrogen production rate were 87.90 m L/g and 3.05 m/L (g, h). Again with 0.6% HCl solution pretreatment of corn straw as a substrate for fermentation hydrogen production of single factor and orthogonal test, studied the straw particle size, the substrate concentration, initial p H value of corn straw anaerobic fermentation hydrogen production process.
xiangying eagle analysis technology co., LTD. The corn straw is determined by gas chromatograph XingyingGC7990plus anaerobic hydrogen production, satisfied results.
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。
滕州市翔鹰分析技术有限公司采用XingyingGC7990plus气相色谱仪测定了玉米秸秆厌氧产氢,结果满意。
