利用糖蜜废水作为发酵底物,以有效容积为5.4 L的连续流搅拌槽式反应器(CSTR)作为反应装置,考察了载体强化(颗粒状活性碳)对生物制氢工艺的影响。研究表明,CSTR反应器采用经好氧曝气预处理的污泥作为接种污泥,温度控制在36°C,水力停留时间(HRT)6 h。有机负荷(OLR)在8-24 kg,m3d的范围之间变化时,可以发现产气量和产氢量随着OLR的提高而有所增加。发酵气体的主要成分是CO2和H2,其中H2的含量为38.4％～41％。反应器在OLR 24 kg/m3d时得到了最大产氢率3.56 L。另外,OLR和VSS/SS两者呈现明显的反比关系,线性关系可以表示为y=-0.6x+78(r2=0.4948)。颗粒状活性碳能使产氢系统中氢气的产量,pH值和液相发酵产物更加稳定,可作为发酵产氢的载体强化材料。
