摘　　要：采用厌氧折流板反应器(ABR)中温处理含硝基苯废水,研究了工艺条件和硝基苯的降解特点。试验结果表明:在进水COD浓度为2088 mg/L,硝基苯浓度为16.8 mg/L,反应温度为35℃,停留时间为24 h条件下,ABR能有效处理硝基苯废水,COD去除率为86.4%,硝基苯去除率为91.1%;在厌氧条件下,硝基苯降解为苯胺,但苯胺很难再进一步分解;硝基苯的去除历程推断为先吸附后分解。Anaerobic baffled reactor （ABR） was used to treat nitrobenzene wastewater at medium temperature and the technologic parameters and characteristics of the nitrobenzene biodegradation were studied. The resuits of experiment showed： ABR could treat the aniline wastewater effectively when the COD was 2088 mg/L, nitrobenzene concentration was 16.8 mg/L and HRT was 24 h at 35 ℃. The COD removal rate was 86.4% and the nitrobenzene removal rate was 91.1%. Under the anaerobic condition nitrobenzene biodegraded into aniline, however, it was difficult for aniline degrading. It was deduced that nitrobenzene removing process was absorption first and degradation later.
