摘要
为研发高效厌氧生物反应器,采用模拟有机废水,对分段组合式厌氧反应器的运行性能进行了研究。试验结果表明:该反应器具有很高容积效能,容积负荷可达110.97g/(L·d),容积负荷去除率可达84.35g/(L·d),容积产气率可达57.00L/(L·d)。该反应器内的基质浓度及中间产物浓度较高,平均化学需氧量和挥发性有机酸浓度分别是常效反应器相应值的18.49倍与37.52倍,可提供较大的反应推动力。该反应器具有良好的运行性能,但趋近满负荷时性能参数波动较大,易导致反应器工况失稳。
To exploit high-efficiency anaerobic reactors,the performance of compartmentalized anaerobic reactor（CAR） was investigated in lab-scale.The results showed that CAR could reach a high volumetric efficiency.The organic loading rate（OLR）,volumetric chemical oxygen demand removal rate and volumetric biogas production were 110.97 g/（L·d）,84.35 g /（L·d） and 57.00 L/（L·d）,respectively.The concentrations of chemical oxygen demand（COD） and volatile fatty acids（VFA） during high-loading were 18.49 and 37.52 times as high as their counterparts during common-loading stage,which provided a greater driving force for the anaerobic reaction.The working performances were good when CAR was away from the OLR saturability,but they became unstable when CAR approached to the OLR saturability.
