摘　　要：建立缺氧的模拟生物处理体系经过物化预处理的采油废水,利用荧光原位杂交技术(FISH)跟踪了废水处理系统启动和稳定过程中真细菌和古细菌相对丰度的变化.结果表明,系统稳定后的COD去除率在40%左右.细菌和古细菌在采油废水生物处理系统中都有很高的比例,并呈现不同的变化趋势.细菌丰度在启动和稳定后维持在15%左右;而古细菌在系统稳定过程中呈现逐渐增加的趋势,比例上升到21%.表明古细菌可以在活性污泥系统中稳定存在并发挥作用,说明古细菌在特定污水处理上具有一定的研究和应用价值.The simulated anoxic sludge system used for the treatment of oil production wastewater was set up to study the change in richness of eubacteria and archaea by fluorescence in situ hybridization （FISH）. The result indicated that COD removal rate was about 40% when the system was stable. The ratios of eubacteria （EUB338） and archaea （Arch915） to DAPI were used to indicate the community richness, indicating that both eubacteria and archaea occupied higher ratio in the system. And the ratio of eubacteria, about 15%, was found stable, while that of archaea increased from 15% to 21% during the treatment process. It suggested that archaea would exist in the sludge and contributed to COD removal. Fig 4, Tab 2, Ref 14
