| 摘 要： | 采用连续流搅拌槽式反应器(CSTR)作为反应装置,探讨了制糖废水厌氧发酵法生物制氢的可行性与运行特征。研究表明,在污泥接种量(以挥发性悬浮固体计)为17.74 g/L,温度为(35±1)℃,水力停留时间(HRT)为6 h,通过调节有机负荷,在12 d左右就可以快速实现生物制氢反应器中微生物的主要代谢类型为乙醇型发酵;而且此时的CSTR产氢发酵系统对负荷冲击表现出了良好的调节能力,在有机负荷(以化学需氧量COD计)从8 kg/(m3.d)提高到24 kg/(m3.d)时,反应系统可在9 d内重新达到稳定运行状态,其COD去除率和产气量由8%和3 L/d提高到20%和12 L/d,发酵气中氢气体积分数为67%。 |

| Abstract: | The feasibility and operation characteristics of anaerobic fermentation biohydrogen production in a continuous stirred-tank reactor (CSTR) were investigated for treating beet-sugar processing wastewater. The research indicates that the reactor has the capacity of continuously producing hydrogen in an initial biomass (as volatile suspension solids) of 17.74 g/L, temperature of (35±1) ℃, hydraulic retention time (HRT) of 6 h, and the reactor can start up the ethanol-type fermentation with COD organic loading rate (OLR) in 12 d and realize stable hydrogen production. Furthermore, the CSTR reactor enjoys a favorable stability even with an organic shock loading. When the organic loading rate (as COD) rises from 8 kg/(m~3·d) to 24 kg/(m~3·d), the CSTR system can reach a new steady state within 9 d. COD removal rate increases from 8% to 20%, the biogases yield increases from 3 L/d to 12 L/d, and the hydrogen volume fraction in the biogas is 67%. |
