摘要
曝气生物滤池(BAF)是一种集吸附、过滤和生物氧化为一体的新型污水生物处理技术.本文介绍了影响BAF运行效果的因素(如填料、水力负荷、气水比、反冲洗、C/N 和温度等),综述了 BAF 在去除水中各类污染物质的最新研究进展,并就该工艺在有机及悬浮物去除、硝化除氨、脱氮除磷、耦合其他工艺等方面所具备的优势与不足进行了阐述,为BAF的发展与应用研究提供一定的科学参考.
Abstract
Biological aerated filter(BAF)was a new biological treatment technology of sewage which integrated adsorption,filtration and biological oxidation.The factors affecting the operation effect of BAF,such as filling,hydraulic load,gas-water ratio,backwash,C/N,temperature,etc.,were introduced.The latest research progress of BAF in the removal of various pollutants in water was reviewed,and the advantages and disadvantages of this process in organic and suspended matter removal,nitrification and ammonia removal,nitrogen and phosphorus removal,coupled with other processes were described,which provided certain scientific reference for the development and application of BAF.
