摘　　要：为解决连续流搅拌槽式反应器(CSTR)发酵制氢系统存在的不足,如单位基质氢气转化率低、因搅拌带来的耗能,抗负荷冲击能力不强等问题,开展了厌氧折流板反应器(ABR)发酵产氢的研究.结果表明,在35℃和进水COD 5000mg/L等条件下,ABR系统可在26d达到乙醇型发酵,其比产氢速率为0.13L/(gMLVSS.d),而在同样条件下,CSTR达到乙醇型发酵后,比产氢速率仅为0.06L/(gMLVSS.d).ABR通过生物相的分离,使产氢系统梯级利用有机物并达到深度产氢的目的.与CSTR相比,ABR具有较高的产氢活性、较低能源消耗等优点,是一种较为理想的有机废水发酵制氢反应设备.To solve the continuous-flow stirred tank reactor（CSTR） hydrogen system has low efficient and waste energy,a 3-compartment anaerobic baffled reactor（ABR）,with an effective volume of 27.8L,was adapted and its performing characteristics and hydrogen production efficiency were investigated,using diluted molasses as the material.ABR had higher efficiency and lower energy consumption comparing with CSTR.ABR achieved stable ethanol type fermentation within 26d with 35℃ and initial COD of 5000mg/L,and the specific hydrogen production rate was 0.13L/（gMLVSS？d） while that of CSTR under the same conditions was 0.06L/g MLVSS？d.Results showed that ABR was an ideal facility for hydrogen production from organic wastewater fermentation.
