摘要： 分别从位于渤海、南海的16座海上石油平台生化法污水处理装置中选取活性污泥样本,对其开展16S核糖体RNA基因测序,基于获取、观察到的物种数指数、香农多样性指数及系统发育多样性指数,探究海上石油平台生化法污水处理装置中微生物群落的组成与结构。结果表明,活性污泥中富含对化学需氧量去除有积极作用的多种功能菌,且不同平台的污水中微生物群落组成与结构略有差异。

Abstract: This study collected activated sludge samples from biological wastewater treatment systems on sixteen offshore oil platforms located in the Bohai Sea and South China Sea. Through 16S rRNA gene sequencing of the activated sludge samples,the composition and structure of microbial communities in these offshore domestic wastewater treatment systems were investigated by calculating the Observed Species index,Shannon index,and phylogenetic diversity （PD） index. The results reveal that the activated sludge harbors abundant functional bacteria contributing to the removal of chemical oxygen demand （COD）. Slight differences in microbial community composition and structure were observed among different platforms.

Key words: offshore oil platforms, domestic wastewater treatment system, microbial community, 16S rRNA
