摘　　要：为了了解采油废水ABR厌氧处理系统中起主要作用的微生物种群,利用高通量测序手段分析了北海涠洲岛采油废水处理终端ABR厌氧反应池内的微生物群落特征。结果表明,ABR反应池内活性污泥中的细菌主要是产甲烷菌,主要来源于变形菌门、厚壁菌门、拟杆菌门和热袍菌门。目前已经形成了以产甲烷菌介导的稳定的功能降解菌群。真菌主要来源于三个门类:Ascomycota、Basidiomycota和Zygomycota,对于采油废水中的组分均有一定的降解作用。Characteristics of microbial community in an anaerobic ABR system for treating oil-field wastewater are analyzed,in which polymerase chain reaction and high-throughput sequencing methods are used.The results show that the bacteria community in the ABR system is mainly composed of methanogens,including proteobacteria,firmicutes,bacteroidetes and thermotogae.These bacteria are commonly found in methanogenic hydrocarbon degrading environment,suggesting that they can be involved in the degradation of oil-field wastewater.In addition,fungal community including Ascomycota,Basidiomycota,and Zygomycota is abundant in the ABR system and bacteria and fungal in ABR tank can efficiently degradate components of oil-field wastewater.
