摘　　要：以玉米秸秆水解液作为产氢底物,研究光合菌群产氢性能。考察了硫酸浓度、固液比、水解时间、水解温度等秸秆水解条件对产氢的影响,确定了最佳水解条件,并对不同脱毒方法进行了对比研究。结果表明,最佳的水解条件为硫酸浓度1%,固液比1:12,水解时间0.5 h,水解温度为110°C。采用Ca(OH)2脱毒方法的产氢效果要优于其他2种脱毒方法;NH4+在一定浓度范围内对该光合菌群产氢有促进作用。Hydrogen production of photosynthetic bacteria group was studied using corn stalk hydro-lyzate as hydrogen production substrate.The affects of sulfuric acid concentration,solid-liquid ratio,hydrolysis time and hydrolysis temperature on hydrogen production were investigated.The optimum process conditions were as follows： the sulfuric acid concentration was 1%,the solid-liquid ratio was 1：12,the hydrolysis time was 0.5 h and the hydrolysis temperature was 110 °C,respectively.Three hy-drolyzate detoxification methods were compared and the method of calcium hydroxide obtained the op-timal detoxification effect.NH4＋ played a stimulatory role to the hydrogen production within certain concentration.
