摘　　要：生物砂滤池是对传统石英砂滤池进行生物强化,在石英砂滤料表面培养附着生物膜,具有运行管理简便、处理效果好等特点,可用于污水厂尾水的深度处理,但石英砂滤料的表面特性一定程度上限制了生物砂滤池的挂膜效果与除污效能。综述了生物砂滤池工艺的特点、成膜行为及运行效果的影响因素,论述了石英砂滤料的改性方法,并对改性砂滤池深度处理污水厂尾水的研究进行了展望,以期为生物砂滤池的系统深入研究及工程应用提供理论依据。Biological sand filter is the bio-strengthen process of traditional quartz sand filter,which culture biofilm on the surface of quartz sand filter material,and has characteristics of simple operation and management,good treatment effect,and so on,therefore,it can be used for advanced treatment of tail water from sewage treatment plant.However,the surface characteristics of the quartz sand filter material limit the biofilm formation and the pollutants removal efficiency of biological sand filter.The process characteristics,biofilm formation behaviors and influencing factors of biological sand filter process were summarized,the modification methods of quartz sand filter material were discussed,and the research on advanced treatment of tail water from sewage treatment plant by modified sand filter was prospected,hoping to provide theoretical basis for systematic research and engineering application of biological sand filter.
