摘　　要：采用厌氧折流板反应器在中温(37℃)条件下处理以蔗糖为基质的邻硝基苯胺废水.采用低负荷高去除率的方法驯化污泥,COD浓度采用标准重镉酸钾法,邻硝基苯胺浓度采用萘乙二胺偶氮光度法测定.结果表明:在进水邻硝基苯胺浓度小于8mg/L,COD浓度为1200mg/L,HRT为1d时,反应器运行稳定,邻硝基苯胺的去除率和COD去除率分别达84%和85%.当进水邻硝基苯胺浓度提高到15mg/L时,邻硝基苯胺和COD的去除率仅分别降低11%和4%,表明厌氧折流板反应器对冲击负荷的适应能力较强.<Abstrcat>　The wastewater containing sucrose and O-Nitroaniline is treated with anaerobic baffled reactor. When the reactor is operated at temperature of 37　℃, the strength of O-Nitroaniline is less than 8　mg/L. HRT of 1 d and the influent COD of 1 200 mg/L, The results demonstrate that the removal of O-Nitroaniline and COD are respectively 84% and 85%. When the influent concentration of O-Nitroaniline increases to 15 mg/L, the removal of O-Nitroaniline and COD decrease respectively by 11% and 4%. It showed strong adaptability of anaerobic baffled reactor against shock load.
