A novel continuous mixed immobilized sludge reactor (CMISR) containing activated carbon as support carrier was used for fermentative hydrogen production from molasses wastewater. When the CMISR system operated at the conditions of influent COD of 2000-6000mg/L, hydraulic retention time (HRT) of 6h and temperature of 35°C, stable ethanol type fermentation was formed after 40days operation. The H(2) content in biogas and chemical oxygen demand (COD) removal were estimated to be 46.6% and 13%, respectively. The effects of organic loading rates (OLRs) on the CMISR hydrogen production system were also investigated. It was found that the maximum hydrogen production rate of 12.51mmol/hL was obtained at OLR of 32kg/m(3)d and the maximum hydrogen yield by substrate consumed of 130.57mmol/mol happened at OLR of 16kg/m(3)d. Therefore, the continuous mixed immobilized sludge reactor (CMISR) could be a promising immobilized system for fermentative hydrogen production.
一种新型的连续混合固定污泥反应器（CMISR），含有活性炭作为载体，用于从糖蜜废水中发酵生产氢气。当 CMISR 系统在进水 COD 为 2000-6000mg/L、水力停留时间（HRT）为 6h 和温度为 35°C 的条件下运行 40 天时，经过 40 天的运行后，形成了稳定的乙醇型发酵。沼气中 H(2)的含量和化学需氧量（COD）去除率分别估计为 46.6%和 13%。还研究了有机负荷率（OLR）对 CMISR 制氢系统的影响。结果表明，在 OLR 为 32kg/m(3)d 时，最大产氢率为 12.51mmol/hL，在 OLR 为 16kg/m(3)d 时，底物消耗的最大产氢量为 130.57mmol/mol。因此，连续混合固定污泥反应器（CMISR）可能是一种很有前途的发酵制氢固定化系统。
