| 摘 要： | 应用生物滴滤塔处理甲基叔丁基醚废气,研究其挂膜启动及稳定运行阶段的降解性能,并考察了稳定期该系统的生物群落结构.结果表明,生物滴滤塔在停留时间为60 s,进气质量浓度为100 mg·m~(-3)的条件下,运行23 d后完成挂膜,填料上的生物量明显增加,去除率可维持在70%以上.反应器稳定运行时,去除负荷可达13.47 g·(m3·h)~(-1),矿化率可达68%;用Haldane模型拟合生物滴滤塔中去除负荷的变化趋势,获得理论ECmax为21.03 g·(m3·h)~(-1),KS为0.16 g·m~(-3),KI为0.99g·m~(-3).运用高通量测序技术分析生物膜中的微生物群落结构,发现其中优势菌属为Methylibium sp.和Blastocatella sp.,分别占11.33%和9.95%.

| Abstract: | The performance and microbial communities of methyl tert-butyl ether (MTBE) treatment using a biotrickling filter (BTF) that was inoculated with activated sewage sludge were investigated. The BTF successfully started up within 23 days when the inlet concentration of MTBE was 100 mg·m-3 and empty bed retention time was 60 s, with 70% removal efficiency (RE). Under steady-state conditions, an elimination capacity (EC) and a mineralization ratio of 13.47 g·(m3·h)-1 and 68% were achieved, respectively. The ECmax was 21.03 g·(m3·h)-1 according to the Haldane model, and a KS of 0.16 g·m-3 and KI of 0.99 g·m-3 were obtained. High-throughput sequencing was used to identify the community structure of the mixed microbial consortium in the BTF. The results indicated that Methylibium sp. (11.33%) and Blastocatella sp. (9.95%) were the dominant bacteria. |
