Abstract

The performance and microbial communities of methyl -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 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·(m·h) and 68% were achieved, respectively. The EC was 21.03 g·(m·h) according to the Haldane model, and a of 0.16 g·m and of 0.99 g·m were obtained. High-throughput sequencing was used to identify the community structure of the mixed microbial consortium in the BTF. The results indicated that sp. (11.33%) and sp. (9.95%) were the dominant bacteria.

摘要

研究了接种活性污水污泥的生物滴滤池（BTF）处理甲基叔丁基醚（MTBE）的性能和微生物群落。当MTBE进口浓度为100mg·m且空床停留时间为60s时，BTF在23天内成功启动，去除效率（RE）达70%。在稳态条件下，消除容量（EC）和矿化率分别达到13.47g·(m·h)和68%。根据Haldane模型，EC为21.03g·(m·h)，得到Ks为0.16g·m和Ki为0.99g·m。采用高通量测序技术鉴定BTF中混合微生物群落的结构。结果表明，某菌属（11.33%）和某菌属（9.95%）是优势细菌。
