曝气生物滤池技术进展

Progress on Biological Aerated Filter Technique

曝气生物滤池(BAF)是一种集生物氧化、过滤、吸附于一体的新型生物膜污水处理技术。文章介绍了BAF的发展沿革,综述了BAF在填料、生物膜、有机物、SS、氨氮去除、脱氮除磷、有毒有害物质降解方面的最新进展,拓宽了BAF组合工艺的研究和应用范围,指出BAF作为一种深度处理工艺是非常适合于我国国情的水处理技术,尤其对我国今后中水回用、企业污水闭路循环以及"零排放"具有重要意义,应加大研发和开发力度,推广其应用。

Biological aerated filte(rBAF)is gathering in biological oxidation,filtration and adsorption as a novel biofilm water treatment technology.Origin and development of BAF were introduced,research progress in the media,biofilm,removal of organic matters,suspended solid and ammonia,nitrogen and phosphorus,toxic and harmful substances were reviewed,which would widen the application of BAF combined process.It was pointed that BAF as an advanced treatment process is suitable to conditions in China,especially for water reuse,business closed water cycle and zero discharge in future.More studies and development should be done to expand the application.
