摘  要：
[目的]比较复合式厌氧折流板反应器(HABR)与连续流搅拌槽式反应器(CSTR)乙醇型发酵产氢的运行效果。[方法]以红糖为底物进行两种反应器的乙醇型发酵制氢,监测系统的产氢效能、产能效能、生物量以及COD去除率变化。接种污泥的生物量为15.21g/L,COD浓度分别为4 000、6 000、8 000 mg/L各运行30 d,进水pH为7~8,水力停留时间为12 h。[结果]HABR系统的产氢效能、产能效能、生物量以及COD去除率随COD的提高而上升,在COD为8 000 mg/L时分别达到了17.54 mmol/(h·L)、45.13 kJ/(h·L)、38.11 g/L、42.87%。CSTR系统在COD为6 000 mg/L时效果最佳,产氢效能、产能效能、生物量以及COD去除率分别为13.26 mmol/(h·L)、33.00 kJ/(h·L)、19.91 g/L、26.47%。随着COD的进一步提高,运行效果显著下降。[结论]HABR在高有机负荷的条件下乙醇型发酵产氢效果整体优于CSTR,更适用于工业生产。

摘  要：
[Objective]The research aimed to study the difference of hydrogen production efficiency between two kinds of reactors,hybrid anaerobic baffle reactor( HABR) and continuous flow stirred tank reactor( CSTR).[Method] Brown sugar was used as a substrate for ethanol fermentation hydrogen production. And the hydrogen production efficiency,production efficiency,biomass and COD removal rate of the two kinds of reactors was determined,with biomass of inoculation sludge of 15. 21 g / L,COD concentration of 4000,6000,8000 mg / L for running 30 d respectively,pH value between 7-8,hydraulic retention time of 12 h.[Result]The results showed that hydrogen production efficiency, production efficiency,biomass and COD removal rate of HABR system increase with the increase of COD,and reached 17. 54 L / h,45. 13 kJ /( h·L),38. 11 g / L,42. 87% respectively when COD was 8 000 mg / L. But the best condition of CSTR system occured for COD of 6 000 mg / L,production efficiency,production efficiency,biomass and the COD removal rate were 13. 26 mmol /( h · L),33. 00 kJ /( h · L), 19. 91 g / L,26. 47% respectively. With the further increase of COD,a significant decrease happened.[Conclusion] HABR is more suitable for industrial production than CSTR,for its higher hydrogen production efficiency under the condition of high organic loading.
