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 ;
Based on analysis of degradation and transformation of organic compounds in coke plant wastewater through every stage of the A 1 A 2 O biofilm system,several typical nitrogen heterocyclic compounds (pyridine,indole,quinoline,isoquinoline,2\|methyl quinoline and 8\|hydroxyl quinoline) in coke plant wastewater were selected for the study. The results showed that when phenol is as co\|substrate,these compounds nearly all be removed after treatment by A 1 A 2 O process.Under the anaerobic condition,the order of degradation rate is indole>2\|methyl quinoline>8\|hydroxyl 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.
