摘要
活性污泥法是污水处理最重要的生物处理工艺之一,活性污泥系统中的细菌群落是该技术的核心,准确地了解活性污泥中微生物的群落结构、关键功能、细菌的生理特性和作用机制是提高活性污泥处理工艺运行效果的重要依据。文章通过对相关文献的总结和分析,综述了活性污泥处理工艺中主要细菌群落(脱氮除磷细菌、丝状菌等)的多样性和生理生态学特征,为提高污水处理厂运行效能、增强功能稳定性提供一定的微生物学理论基础。
Activated sludge process is one of the most important biological technologies of wastewater treatment. Bacterial communities of the activated sludge system are the core of such technology. Accurate understanding of the composition and dynamics of microbial communities in the activated sludge, the physiological features and mechanism of key functional bacteria are the important basis for improvement of the operation effect of the activated sludge process. In this paper, based on the summary and analysis of relevant literature, diversity, physiological and ecological characteristics of the main microbial communities（e.g. nutrient removal bacteria, filamentous bacteria） in the activated sludge treatment process are reviewed, providing a certain theoretical basis for improvement of the operation efficiency and enhancement of the functional stability of sewage treatment plants.
