摘　　要：在低温条件下采用厌氧折流板反应器（ABR）对含硝基苯污水进行酸化预处理。试验结果表明：在水温为5~10℃,水力停留时间（HRT）为3 h条件下,连续3天同时向单侧和分区进水ABR中投加含硝基苯0.48 mg/L的生活污水,表现为反应器出水COD、TOC浓度同步下降,历经3周后,两反应器性能基本恢复正常,表明低温条件下ABR反应器具有一定的抗短期硝基苯冲击能力,其中分区进水ABR的性能更优。Acidification pretreatment of nitrobenzene wastewater with the anaerobic baffled reactor（ABR） was carried out under low temperature. The results show that under the conditions of hydraulic retention time 3 h and water temperature 5 - 10 ℃ , adding 0.48 mg/L nitrobenzene wastewater into the single side feed ABR and split feed ABR three days continuously, COD and TOC concentration in effluent water of the reactor decrease at the same time. After three weeks,properties of the two reactors are recovered. It is proved that the ABR is highly adapted to nitrobenzene wastewater even under the condition of low temperature, especially split feed ABR.
