摘要:
采用自制河流模拟系统，对比了聚氨酯和聚乙烯组合填料生物接触氧化法在改性前后对污染物的去除效果。相比改性前，改性后系统启动挂膜时间由20 d缩短至13 d。系统长期稳定运行结果表明，在填充比为50%和溶解氧（DO）浓度为4 mg/L的条件下，系统对NH4+-N、TN、TP、COD的去除率分别提高了10.08%、9.89%、36.93%和17.84%。污染物去除率的提升归因于微生物群落的变化和功能菌群的富集。基于高通量测序技术的生物膜群落分析结果表明，相比改性前，组合改性填料的微生物多样性Ace、Chao和Shannon指数明显升高。变形菌门（Proteobacteria）、厚壁菌门（Firmicutes）、拟杆菌门（Bacteroidetes）和硝化螺旋菌门（Nitrospirae）等成为优势菌门。改性生物膜功能菌群如氨氧化细菌（AOB）和亚硝酸盐氧化菌（NOB）丰度比改性前分别提升了78.7%和36.5%。
Abstract:
A self-constructed river simulation system was employed to evaluate and compare the removal efficiency of pollutants using polyurethane and polyethylene composite packing media in a biological contact oxidation process before and after modification. Following the modification, the system’s startup period for biofilm formation was reduced from 20 days to 13 days. During long-term operation, the system achieved enhanced removal efficiencies for NH4+-N, TN, TP, and COD under conditions of a 50% filling ratio and dissolved oxygen (DO) concentration of 4 mg/L, with improvements of 10.08%, 9.89%, 36.93%, and 17.84%, respectively. The enhancement in pollutant removal efficiency could be attributed to shifts in microbial community composition and the enrichment of functional microbial populations. The analysis results of biofilm communities based on high-throughput sequencing technology indicated that the microbial diversity indices including Ace, Chao, and Shannon of the composite packing media were significantly increased compared with the pre-modification state. The phyla Proteobacteria, Firmicutes, Bacteroidetes, and Nitrospirae, ect. emerged as the dominant bacterial groups. The abundance of functional bacteria in the modified biofilms, including ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB), increased by 78.7% and 36.5% relative to pre-modification levels.
