【摘要】 曝气生物滤池(BAF)是一个浸没式的曝气三相反应器,该反应器通过生化反应和过滤作用去除污染物。经过二十几年的发展,BAF工艺不仅成为滴滤池和活性污泥法等二级处理工艺的革新竞争工艺,同时还是一种优良的深度处理工艺和微污染水源水预处理工艺。文章通过总结BAF工艺在国内外的研究进展及其各种形式的应用现状,指出了该工艺现存的一些问题,以及需要重点研究的方向。更多还原

【Abstract】 The biological aerated filter(BAF) combines both biological treatment and solids removal in one submerged,aerated three phase reactor.Over the past 20 years,biological aerated filters have been developed not only as innovative competitors for other secondary treatment systems such as trickling filters and activated sludge processes but also as advanced treatment systems or pre-purification processes for micro-polluted source water.This work endeavored to summarize both the advance of BAF and the application cases of all kinds of BAF.Furthermore,the problems and difficulties presented were indicated,and the key points needed to be deliberatively studied were discovered.更多还原
