Abstract：In this paper, the principle and characteristics of biological aerated filter (BAF) are primarily introduced and the treatment effect of BAF on organic and suspended matter, phosphorus and ammonia nitrogen is also discussed. In addition, the effects of temperature, gas-water ratio, dissolved oxygen, hydraulic load, filler, back-washing method and bio-film way are discussed in order to provide reference for selecting the appropriate operating parameters in practical engineering. According to the development of BAF in the past, the problems existing in BAF and its development trend can be found out. In the future, various combination processes and efficient pretreatment technologies should be paid more attention to.

Keywords: biological aerated filter; water treatment ; treatment effect ; development trend
