摘　　要：以启动成功的厌氧折流板生物制氢反应器(ABR)作为实验装置,并以配置不同有机负荷质量浓度的红糖废水作为实验底物,通过分阶段调控水力停留时间(HRT)和进水COD质量浓度的方式研究了5,6.7,10,12,14,16 kg/(m^3·d)6种不同有机负荷对ABR系统的影响。实验结果表明,当受到一定范围内的有机负荷冲击时,ABR系统经过2—5 d的适应期可以恢复稳定,且适应期随反应的进行逐渐缩短,说明在一定范围内随着有机负荷的提高,ABR系统的稳定性能逐渐增强;当HRT为12 h、进水COD质量浓度达到8000 mg/L时[有机负荷(COD)约16 kg/(m^3·d)],有机负荷超出ABR系统承受能力并导致系统发生酸化,pH值最低降低到3.98,COD去除率及总产氢速率降低。本研究为ABR反应器在实际中的运用提供了理论基础。The activated anaerobic baffled reactor(ABR)was tested with different OLR concentrations brown-sugar wastewater.Six different organic load rates(OLR)of 5,6.7,10,12,14 and 16 kg/(m 3·d)were selected through adjusting HRT and inlet COD concentrations to test the influence on ABR system.The result shows that within a certain range of OLR,the system restores stability after 2-5 d adaptation period and the duration gradually decreases with further reaction.The result indicates that with the increase of OLR concentration in certain range,the stability of the ABR system is enhanced.However,when the OLR concentration was 16 kg/(m 3·d)(with 12 h HRT and 8000 mg/L mass concentration of influent COD),the ABR system is acidified with the minimum pH value of 3.98 and the decrease of COD removal rate and total hydrogen rate.The theoretical basis for the application of ABR in practical engineering is provided.
