【摘要】：為了研究紫花苜蓿酶解液作為光合制氫原料時的最佳產(chǎn)氫工藝條件,對產(chǎn)氫影響較為顯著的溫度、光照強度、初始pH值三種因素設(shè)計了三因素三水平L9(33)正交實驗,并對實驗結(jié)果進(jìn)行直觀分析與方差分析,以獲取最佳產(chǎn)氫工藝條件。實驗結(jié)果表明:在所選水平范圍內(nèi),各因素對能源草產(chǎn)氫的影響主次順序為溫度→光照強度→初始pH值;由方差分析可知,溫度和光照強度對能源草光合產(chǎn)氫性能影響為顯著;初始pH值為不顯著;由各因素水平值的均值可見,能源草光合生物制氫的最佳工藝水平為30℃、pH=7、光照度為3 000 lx。
[Abstract]:In order to study the optimum conditions of hydrogen production from alfalfa enzymatic hydrolysis solution as raw material for hydrogen production, three factors, namely temperature, light intensity and initial pH value, which have significant effects on hydrogen production, were designed in this paper. Visual analysis and variance analysis of the experimental results were carried out to obtain the best conditions for hydrogen production. The experimental results showed that in the selected level range, the influence of various factors on hydrogen production of energy grass was in the order of temperature. 鈫扡ight intensity. 鈫扵he effect of temperature and light intensity on photosynthetic hydrogen production of energy grass was significant, initial pH value was not significant. The optimum technological level for hydrogen production by photosynthetic organisms was 30 鈩，
