曝气生物滤池对微污染水的处理研究进展
|
摘要
微污染水受污染的程度较低,对氨氮、磷、有机物和有毒污染物的去除要求较高,生物预处理技术可作为微污染水处理方法之一。近年来生物预处理去除污染技术得到迅速发展,其中曝气生物滤池应用比较广泛。曝气生物滤池(Biological aerated filter,BAF)占地小,运行管理方便且处理出水水质高,在有机物的去除,尤其是在硝化、反硝化脱氮等方面有着良好的效果。文章主要从对氮、磷、COD的去除效果及其不同影响因素进行介绍,分析该技术在微污染水处理中的应用。
The micro-polluted water contains low concentration of pollutants,however,it has high requirements for removal of ammonia nitrogen,phosphorus,organic matter and toxic pollutants. The biological pretreatment technology can be used as one of the main methods for micro-polluted water treatment. In recent years,bio-pretreatment and decontamination technology has rapidly developed,and bio-aeration filters are widely used. The biological aerated filter(BAF) has a lot of advantages,such as small footprint,convenient operation and management,high quality of effluent water,and has high effect in removal of organic matter and nitrogen,especially in nitrification and denitrification. This paper mainly introduces the removal effect of nitrogen,phosphorus and COD and influencing factors of BAF,and analyzes its application in micro-polluted water treatment.
