A coupling system of sodium citrate and biofilm based on polyurethane was prepared to analyse the coupling enhancement degradation on quinoline and indole. Four reactors (R1: sludge, R2: sludge + sodium citrate, R3: biofilm on polyurethane, and R4: biofilm + sodium citrate) were operated 120 days to compare the degradation efficiency. During whole running phases, R4 showed high degradation efficiency on quinoline (≥98.55%) and indole (≥95.44%). Analysis of bacterial colony showed anaerobic sludge reactors benefited the enrichment of , , and , while anaerobic biofilm reactors benefited the enrichment of and . Furthermore, analysis of archaea colony showed acetic acid metabolism to produce methane was the main mode in anaerobic sludge reactors, while acetic acid and hydrogen metabolism to produce methane were both the main modes in biofilm reactors. This study can provide some references for the treatment of nitrogen heterocyclic wastewater.
制备了基于聚氨酯的柠檬酸钠和生物膜偶联系统，以分析喹啉和吲哚的偶联增强降解。运行了四个反应器（R1：污泥，R2：污泥+柠檬酸钠，R3：聚氨酯上的生物膜，R4：生物膜+柠檬酸钠）120 天，以比较降解效率。在整个运行阶段，R4 对喹啉（≥98.55%）和吲哚（≥95.44%）表现出高降解效率。细菌菌落分析表明，厌氧污泥反应器有利于 、 、和的富集，而厌氧生物膜反应器有利于 和 的富集。此外，古菌菌落分析表明，乙酸代谢产生甲烷是厌氧污泥反应器中的主要模式，而乙酸和氢气代谢产生甲烷则是生物膜反应器中的主要模式。本研究可为含氮杂环废水的处理提供一些参考。
