摘　　要：以辽阳市某污水厂的实际处理工艺流程为实验现场,以污水厂的实际运行数据为基础,综合考察了固定化微生物技术对硝基苯类废水的处理效果。结果表明,经过固定化微生物技术处理后,废水中的硝基苯类化合物大多转化,去除率达到90%以上;对COD、BOD_(5)的平均去除率分别为84%、86%。出水中COD、BOD_(5)浓度均达到了《辽宁省污水综合排放标准》(DB 21/1627—2008)的要求,硝基苯类化合物浓度则达到了《污水综合排放标准》(GB 8978—1996)的一级排放标准。但是污水处理系统对废水中的氮类污染物仅有较少去除,针对出水中总氮浓度不达标的情况,提出了相应的改善措施。Treatment effect of immobilized microorganism technology on nitrobenzene wastewater was comprehensively investigated in a practical treatment process of a sewage treatment plant in Liaoyang City based on actual operating data. After treated by the immobilized microorganism technology, most of the nitrobenzene compounds in wastewater were transformed with the removal efficiency more than 90%, and the average removal efficiencies of COD and BOD_(5) were 84% and 86%, respectively. COD and BOD_(5) in the effluent reached the discharge requirements of Liaoning Comprehensive Effluent Standard(DB 21/1627-2008), and nitrobenzene compounds in the effluent reached Integrated Wastewater Discharge Standard(GB 8978-1996). However, the wastewater treatment system removed only a small amount of nitrogen pollutants from the wastewater. In view of the situation that total nitrogen in the effluent was not up to standard, corresponding improvement measures were proposed.
