The aim of the study was to explore the feasibility of methanol, sodium citrate, chlorella, spirulina, and carboxymethylcellulose (CMC) as co-metabolic substances in strengthening the anaerobic degradation of selected nitrogen heterocyclic compounds (NHCs). Chlorella, spirulina, and CMC as co-metabolic substances were first introduced into the enhanced anaerobic treatment of refractory compounds. With the addition of 300 μg/L sodium citrate, chlorella, spirulina, and CMC, reactor 3, reactor 4, reactor 5, and reactor 6 had higher degradation ratios than reactor 2 with methanol as co-metabolic substance. The addition of sodium citrate, chlorella, spirulina, and CMC increased the number of bacterial sequences, promoted the richness and diversity of the bacterial community structure, and enriched the functional genera (Levilinea and Longilinea) responsible for the degradation of quinoline and indole.
本研究旨在探索甲醇、柠檬酸钠、绿球藻、螺旋藻和羧甲基纤维素（CMC）作为共代谢物质在强化选定氮杂环化合物（NHCs）的厌氧降解中的可行性。绿球藻、螺旋藻和 CMC 作为共代谢物质首先被引入到难处理化合物的强化厌氧处理中。在添加 300μg/L 柠檬酸钠、绿球藻、螺旋藻和 CMC 的情况下，与以甲醇作为共代谢物质的 2 号反应器相比，3 号、4 号、5 号和 6 号反应器具有更高的降解率。添加柠檬酸钠、绿球藻、螺旋藻和 CMC 增加了细菌序列的数量，促进了细菌群落结构的丰富度和多样性，并丰富了负责降解喹啉和吲哚的功能属（Levilinea 和 Longilinea）。
