摘　　要： 采用连续流和静态试验进行了模拟淀粉废水厌氧发酵法生物制氢,探讨了有机负荷（OLR）和pH值对产氢能力和液相末端产物的影响.在连续流反应器中,发酵气体产量和氢产量随负荷的增加而升高;当发酵类型为乙醇型,pH 3.9,有机负荷率为22.0 kg COD/（m^3·d）时可同时获得最大气体产量和氢气产量;最大比氢产率为87.5 ml H2/g淀粉.在静态试验中,初始pH值在3.5～4.3时,氢气产量随着pH值增加而增加;pH值范围在4.3～5.0时氢气产量先是下降随后保持稳定,pH 4.3时获得最大氢气产量,最大比氢产率为80 ml H2/g淀粉.结果表明,淀粉废水可以作为厌氧发酵法生物制氢底物. The experiments of anaerobic fermentation hydrogen bio-production （HBP） from simulated starch wastewater were conducted in continuous and batch reactor. Effects of organic loading rate （OLR） and pH on hydrogen production capacity and liquid products were investigated. The biogas yield and hydrogen yield increased with the increasing of OLR in CSTR. After the ethanol-type fermentation was obtained, at pH 3.9, the CSTR obtained maximum biogas yield and hydrogen yield（87.5 ml H2/g starch） simultaneously when the organic loading rate was at 22.0 kg COD/（m^3·d）. In batch reactor, hydrogen yields increased with the increasing of initial pH value from 3.5 to 4.3, then decreased and kept stabilization at pH 4.3 and 5. The maximum hydrogen yield was 80.0 ml H2/g starch at initial pH 4.3. The results indicated that it＇s possible to produce hydrogen from starch wastewater.
