摘 要: 曝气生物滤池(BAF)是一种新型的生物氧化处理工艺,已被广泛应用于城市废水处理、中水回用及微污染源水的预处理。详细论述了目前国内外对BAF效能的关键影响因素,如填料、水力停留时间、进水底物、水温、曝气量与进水量比、反冲洗工艺、化学除磷药剂等的研究现状,并探讨了其今后的研究方向。 Biological aerated filter (BAF) is a new kind of biological oxidation process, which is applied widely in treatment of municipal wastewater, reuse of reclaimed water and pretreatment of slightly polluted source water. The status of research on the key factors affecting BAF performance at home and abroad is introduced, such as : packing, HRT, influent substrate, wastewater temperature, volume ratio of aeration flow to influent flow, backwashing process, chemical reagents for dephosphorization and so on. The direction for further research is also discussed.
