摘要： 对UASB处理含油废水的效能和运行特征进行了研究，并通过高通量测序手段，分析了系统微生物群落结构的动态变化。实验结果表明，投加葡萄糖，采用逐步降低HRT和提高含油废水COD的运行方式，60 d可完成反应器启动。稳定运行期[有机负荷为8~10 kg/（m³·d）]，颗粒污泥的粒径为0.46~0.60 mm，COD平均去除率可达89.14%。进水基质会改变系统菌群结构，当含油废水为唯一碳源，系统内产甲烷菌、水解酸化菌和石油降解菌大量增殖，保证了UASB的高效稳定运行。

Abstract: The efficiency and operation characteristics of UASB for the treatment of oil-bearing wastewater have been researched,and the dynamic changes of system micro-flora structure analyzed by high flux sequencing means. The experimental results show that it takes 60 days to complete the reactor start-up by means of decreasing HRT and increasing the oil-bearing wastewater COD. During the stable operation period[OLR=8~10 kg/(m³·d)], the particle sizes of granular sludge are in the range of 0.46~0.60 mm,and the average COD removing rate can reach 89.14%. The influent substrates can change the structure of the system micro-flora. When oil-bearing wastewater is the only carbon source,the methanogens,hydrolytic acidification bacteria and oil-degrading bacteria produced in the system are proliferated greatly,which ensures UASB to run efficiently and stably.
