摘　　要：本研究利用本公司研制的厌氧复合菌剂生物强化降解含氮杂环废水,对比了不同停留时间下厌氧生化效果。数据显示,生化效果最佳的是HRT为21 d的实验组,去除率达为57%。对不同停留时间的厌氧实验组中的污泥取样其进行高通量测序,测序结果显示HRT 21 d实验组丰度最高的优势菌属变为Desulfovibrio、Acetobacterium、Desulfomicrobium、Proteiniphilum和Haematobacter。随后通过生物强化方法对厌氧复合菌剂菌群进行了种群优化,验证实验表明,经过生物强化处理之后,HRT7d优化实验组COD去除率达到58%,较未强化实验组提高30%左右,生化效果得到明显提升。In this study, the biodegradation of nitrogen-containing heterocyclic wastewater by anaerobic compound microbial agent developed by our company was studied, and the anaerobic biochemical effects under different HRT were compared through experiments. The data show that the best biochemical effect is the experimental group with HRT of 21 days, and the removal rate is 57 %. High throughput sequencing of sludge samples from anaerobic experimental groups with different residence time showed that the dominant bacteria with the highest abundance in HRT 21 d experimental group changed to Desulfovibrio, Acetobacterium,Desulfomicrobium, Proteiniphilum and Haematobacter. Afterwards, the population of anaerobic compound microbial agent was optimized by bio-enhancement method. The experimental results showed that after bio-enhancement treatment, COD removal rate of HRT7 d optimized experimental group reached 58 %, which was about 30 % higher than that of non-enhanced experimental group, and the biochemical effect was significantly improved.
