摘要:
活性炭（或炭砂）生物滤池是饮用水处理中的重要工艺单元，为了进一步优化生物滤池的运行效能，以南水北调水为水源的两个大型水厂的生物滤池为研究对象，利用宏基因组学和16S rRNA高通量测序技术分析了生物滤池的菌群特征和代谢功能。结果表明，生物滤池中的优势菌属主要为鞘氨醇单胞菌、鞘脂单胞菌、生丝微菌、norank_f_DSSF69、Phreatobacter等。通过宏基因组分析发现，各活性炭生物膜样品的基因组均有较完整的降解芳香类化合物的路径，与宏观上生物滤池对芳香类蛋白质的去除作用相对应。通过重构活性炭样品的基因组获得优势菌属，发现重构出的多个属于鞘氨醇单胞菌科的基因组均具有以间位裂解方式降解邻苯二酚的潜能。
Abstract:
The activated carbon (or carbon-sand) biofilter is an important process unit in drinking water treatment. In order to optimize operational efficiency of the biofilter, microbial community characteristics and metabolic functions in the biofilters of two large waterworks with source water from South-to-North Water Diversion Project were analyzed by using metagenomics and 16S rRNA high throughput sequencing technology. The results showed that the dominant genera were Sphingorhabdus, Sphingomonas, Hyphomicrobium,norank_f_DSSF69,Phreatobacter, etc. Metagenomic analysis found that the genome of each activated carbon biofilm sample had a relatively complete pathway to degrade aromatic compounds, which was corresponding to the macroscopic removal effect of aromatic proteins by the biofilters. The genomes of activated carbon samples were reconstructed to obtain the dominant genus, and the reconstructed genomes of several species belonging to Sphinomonas had the potential to degrade catechol by means of interposition cleavage.
