曝气生物滤池滤料改进研究

Study on the improvement of filter materials in biological aerated filter

以改性滤料和新型滤料为研究对象,分析了组分构成和结构特征,综述了不同的改进方式,阐述了其脱氮除磷及去除诺氟沙星(NOR)、藻类、总有机碳(TOC)、生化需氧量(BOD)、化学需氧量(COD)、总悬浮固体(TSS)效果和机理,展望了曝气生物滤池中滤料的发展前景,为现有滤料的改性、新型滤料的开发及曝气生物滤池中滤料的选择提供参考。

Modified filter materials and new filter materials are taken as the research objects,the different improvement methods are summarized,the composition and structural features are analyzed,and the removal efficiency and mechanism of nitrogen,phosphorus,norfloxacin(NOR),algae,total organic carbon(TOC),biochemical oxygen demand(BOD),chemical oxygen demand(COD),total suspended solids(TSS)are discussed,and the development prospect of filter materials in the biological aerated filter(BAF)is proposed.It provides reference for the modification of existing filter materials,development of new filter materials and selection of filter materials in the biological aerated filter.
