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,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 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,啉啶的加入有利于改善由喹啉和吲哚之间产生的拮抗作用。

关 键 词:焦化废水  含氮杂环化合物  A1-A2-O生物膜系统  厌氧  废水处理  降解特性  有机物

Abstract: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.
Keywords:coke plant wasetwater  nitrogen heterocyclic compounds  A  1  A  2  O biofilm process  anaerobic condition
