20世纪 90年代初在污泥处理系统中发现了氮素形态转化的新途径———厌气铵氧化过程 .厌气铵氧化过程是铵以亚硝酸根为电子受体在自养细菌参数下氧化成氮气的过程 .但目前尚无土壤、河、湖、海底泥等自然系统中是否存在厌气铵氧化过程的报道 .由于该过程无需外加有机碳 ,耗氧和处理产生污泥少 ,用于污泥脱氮成本较低 ,具有很大潜力 .

Wastewater treatment by activated sludge is one of the most important biotechnological processes and has been used for more than 80 years. However, the information on correlations between the microbial community structure and function of activated sludge is less provided. Due to intricate interactions within the microbial community, it is important to detect the prominent population and describe microbial community structure in the wastewater treatment process. Conventional cultivation methods often result in pronounced population shifts in the community structure and lead to a failure to detect dominant bacterial community memmbers. Recently, rRNA targeted oligonucleotide probes were introduced as a new powerful tool in situ monitoring microbial ecology in activated sludge and have made revolutionary progresses. Based on it, microbial ecologists can for the first time determine the true composition of microbial communities. This review introduces the identification of it in structure and function of microbial communities in phosphate removing activated sludge, nitrifying activated sludge, bulking sludge and foaming activated sludge, summarizes most of probes which have been developed and used, analyzes the advantages and disvantages of it.

活性污泥中微生物群落内部关系非常复杂 ,及时对活性污泥中优势菌群和群落内部关系进行监测是污水处理中采取正确措施的关键。历史研究表明传统培养方法经常导致活性污泥优势菌群检测的失败 ,而r RNA- targeted寡核苷酸探针作为一种快速原位监测活性污泥微生物群落结构和功能的新工具被引入 ,使我们对参与污水净化的微生物群落结构和优势菌群能有较全面的了解。就该方法在识别除磷污泥、脱氮污泥、污泥泡沫和膨胀污泥中微生物群落结构和功能的典型应用进行综述 ,分析了该方法存在的优点和缺点 ,并对目前已建立且应用于活性污泥微生物检测的 r RNA- targeted寡核苷酸探针进行了详细总结
