摘　　要：以产氢量为主要考察指标,通过响应面Box-Behnken模型优化大叶黄杨废弃物光合生物制氢的工艺参数,对其主要影响因素之间的关系进行研究。结果表明:温度对大叶黄杨废弃物光合生物制氢工艺的影响最大;光照强度与初始pH值、温度等的交互作用均对产氢量的影响比较显著;最佳产氢工艺条件为温度28.78℃、初始pH值7.00、光照强度3067.0 lx,此时拟合产氢量为71.81 mL/g,实际产氢量为70.15 mL/g;拟合值和实际值的相对误差为2.31%,表明该数值模型具有较好的拟合性。It aimed to optimize the process parameters of photo-fermentative hydrogen production from waste of Buxus megistophylla using Box-Behnken model by taking hydrogen yield as main indicator.The correlations between the main parameters were also evaluated.Temperature was found to have the greatest influence on hydrogen production.The interactions of light intensity with initial pH value and temperature have significant effects on hydrogen production.Under the optimal conditions of temperature of 28.78 C,initial pH value of 7.00 and light intensity of 3067.0 lx,a maximum fitting hydrogen yield of 71.81 mL/g was achieved,which deviated from the actual value(70.15 mL/g)by only 2.31%.The results demonstrated a good fitting of the model with experimental data.
