中文摘要	研究了不同格室数和添加填料与否对折流式厌氧反应器(ABR)启动性能的影响。反应器启动时,控制化学需氧量(COD)初始负荷为1.4 kg/(m3.d),逐渐提升至3.5kg/(m3.d),经过28~63 d连续运行,启动获得成功。试验结果表明,反应器的三格结构和五格结构表现出非常相似的启动特性,增设填料的复合式反应器启动速度明显快于普通折流式厌氧。此外,沿程化学需氧量及挥发酸浓度降解规律和不同格室的颗粒污泥的扫描电镜表明,反应器内微生物相的分布规律与相应格室的基质浓度、类型等保持一致。; The start-up characteristics of two lab-scale anaerobic baffled reactors with three and five compartments were investgrated in a series of tests.The baffles in the hybrid reactor affected the start-up performances.The initial organic loading COD(chemical oxygen demand) was 1.4 kg/(m~3穌) and gradually increased to 3.5 kg/(m~3穌) over a period of 2863 d,after which the reactors then successfully started.The results show that the two reactors had very similar start-up performances,with the hybrid reactor starting sooner than the control reactor.The COD and volatile fatty acid concentrations decreased at lower elevations in the reactor.Scanning electron microscope images of the granular sludge suggests that the anaerobic bactoria in each compartment developed based on their available substrates and specific environmental conditions.; 国家“九五”科技攻关项目(96-909-05-03)
