- 摘要:
- 为探究好氧颗粒污泥（AGS）工艺在实际市政污水处理中的适用性，以泸州某污水处理厂市政污水作为进水基质，接种厂区现有生化段絮状污泥，在中试规模序批式反应器（SBR）系统中进行AGS培养。系统自秋季开始运行至次年春季结束，共运行210 d。结果表明，在10~20 ℃下，采用我国南方地区实际市政污水可以培养出AGS，污泥颗粒化比例稳定在50%以上，最高达56%，SV30/SV5维持在0.8~1.0。SBR稳定运行后对COD、氨氮、总磷的平均去除率分别达到90%、97%、93%。同时，对成熟的AGS和絮状污泥中的微生物群落进行高通量测序分析，结果表明，Proteobacteria是絮状污泥中的优势菌门，而Actinobacteriota在AGS中相对丰度更高，具有脱氮、除磷、除碳功能的菌属Tetrasphaera、Rhodobacter和Azospira等，在AGS中的相对丰度高于絮状污泥。微生物群落分析表明，成熟AGS中微生物群落多样性下降且群落组成发生显著变化。
- Abstract:
- In order to investigate the applicability of the aerobic granular sludge (AGS) process in actual municipal wastewater treatment, municipal wastewater from a wastewater treatment plant in Luzhou was used as the influent substrate, and flocculent sludge from the existing biochemical section of the plant was inoculated to cultivate AGS in a pilot-scale sequencing batch reactor (SBR) system. The system was operated for 210 days, starting from autumn and continuing until the end of the following spring. The results showed that AGS could be successfully cultivated using actual municipal wastewater from southern China at temperatures ranging from 10 ℃ to 20 ℃. The sludge granulation ratio stabilized at over 50%, reaching a maximum of 56%, and the SV30/SV5 ratio was maintained at 0.8-1.0. After stable operation of the SBR, the average removal rates of COD, ammonia nitrogen, and total phosphorus reached 90%, 97%, and 93%, respectively. Meanwhile, high-throughput sequencing analysis of the microbial communities in mature AGS and flocculent sludge revealed that Proteobacteria was the dominant phylum in flocculent sludge, while the relative abundance of Actinobacteriota was significantly higher in AGS. The genera involved in nitrogen removal, phosphorus removal, and carbon removal, such as Tetrasphaera, Rhodobacter, and Azospira, exhibited higher relative abundances in AGS than in flocculent sludge. Microbial community analysis also revealed a decrease in microbial community diversity and significant changes in community composition in mature AGS.
