A new-styled continuous stirred tank reactor (CSTR) seeded with activated sludge attached onto granular activated carbon ( GAC ) was developed for raised hydrogen production using diluted grenadine syrup. Emphasis was placed on the hydrogen producing performance and stability of the reactor. It is found that the temperature of ( 35 ± 1 ) ℃, hydraulic retention time (HRT) of 4 h, influent COD of 6 000 mg/L, the maximum hydrogen production was up to 12.06 L/d. In addition, though pH decreased to 3.42, the microbial growth kept high and COD removal rate reached 50% , demonstrating that the reactor processed the ability of acid resistance.%为提高连续流发酵制氢(CSTR)生物反应器的产氢效能,以红糖水作为发酵底物,通过投加活性炭颗粒作为固定化载体强化活性污泥,形成固定悬浮一体化的新型CSTR反应器.着重探讨反应器内部的稳定性与其产氢性能.结果表明,在温度为(35±1)℃,水力停留时间(HRT)为4h,进水COD为6 000 mg/L时,其最大产氢量可达到12.06 L/d；此外,反应器内部的耐酸性能良好,pH值最低可达3.42,而且在载体颗粒物的作用下,生物量活性保持良好,COD去除率也可高达50％.
