• 摘要：在对焦化废水中有机物在A₁-A₂-O生物膜系统中降解转化规律进行分析的基础上,选取焦化废水中6种主要的含氮杂环化合物:吡啶、吲哚、喹啉、异喹啉、2甲基喹啉、8羟基喹啉,与苯酚共同配制成溶液,在A₁-A₂-O生物膜系统中运行,结果表明上述几种含氮杂环有机物在A₁-A₂-O系统中都可得到较完全的去除.它们在厌氧段的降解速率从大到小依次为:吲哚>2-甲基喹啉>8-羟基喹啉>异喹啉>喹啉>吡啶.在厌氧条件下,吲哚和喹啉存在拮抗作用,而吡啶对喹啉有协同作用;吡啶的加入有利于改善由喹啉和吲哚之间产生的拮抗作用.

• Abstract：Based on analysis of degradation and transformation of organic compounds in coke plant wastewater through every stage of the A_{1sub>-A2-O biofilm system,several typical nitrogen heterocyclic compounds (pyridine,indole,quinoline,isoquinoline,2methyl quinoline and 8hydroxyl quinoline) in coke plant wastewater were selected for the study. The results showed that when phenol is as cosubstrate,these compounds nearly all be removed after treatment by A1sub>-A2-O process.Under the anaerobic condition,the order of degradation rate is indole>2methyl quinoline>8hydroxyl quinoline>isoquinoline>quinoline>pyridine.There exist antagonistic action between indole and quinoline and synergistic action between pyridine and quinoline.When pyridine was added,the antagonism between indole and quinoline decreased.}
