摘要:

研究了好氧颗粒污泥处理印染废水的效果,并对系统中微生物菌群进行了分析。结果表明:颗粒污泥长时间运行会发生解体,但具有自修复潜力。该体系的COD、氨氮、总磷、色度的平均去除率分别为92.53%、56.65%、95.12%、69.03%。微生物测序结果显示:颗粒污泥解体前后的微生物群落发生了显著变化,体系中的优势菌门为变形菌门,其中磁螺菌属Magnetospirillum对染料降解和COD去除起到了重要的作用。

Abstract:

The performance of aerobic granular sludge on textile dyeing wastewater treatment was studied, and the population structure of microorganisms in the system was analyzed. The results showed that granular sludge disintegrated during long-term operation, but had self-repairing potential. The average removal rates of COD, ammonia nitrogen, total phosphorus and chroma were 92.53%, 56.65%, 95.12% and 69.03%, respectively. Microbial sequencing results showed that the microbial community changed significantly before and after the disintegration of granular sludge. The dominant bacteria in the system were Proteobacteria, and the Magnetospirillum played an important role in dye degradation and COD removal.

Key words: aerobic granular sludge, textile dyeing wastewater, biodegradation, microbial population
