摘　　要：采用生物活性炭序批式反应器(BAC-SBR)处理ABS凝聚干燥工段废水,利用紫外可见光谱及红外光谱等技术检测分析废水处理过程中有机污染物的变化,并重点研究分析了该废水中的有毒难降解有机污染物在BAC-SBR反应器中的降解过程。研究结果表明BAC-SBR反应器处理该废水的过程主要包括活性炭吸附、活性炭的生物再生及生物再生完成3个阶段;经过180min的处理,废水的COD和TOC去除率均能达到85%以上;并且通过紫外可见光谱和红外光谱检测分析可知该反应器能够高效地降解转化废水中的芳香类及有机腈类有毒有害污染物。Wastewater from ABS condensation drying section is treated by biological activated carbon-sequencing batch reactor（BAC-SBR）,and degradation process of the toxic and hazardous pollutants in ABS wastewater is studied significantly by using UV-visible spectrum and Fourier transform infrared spectroscopy（FTIR）.The results show that the treatment process of ABS wastewater by BAC-SBR contained three phases of adsorption,bioregeneration and completion.The COD and TOC removal efficiencies of ABS wastewater are both more than 85% after 180 min treatment in BAC-SBR reactor,and the analysis results of UV-vis and FTIR suggest that the toxic and hazardous pollutants i.e.,aromatic compounds and organic nitriles in ABS wastewater can be decomposed and transformed efficiently by BAC-SBR reactor.
