Introduction: In order to solve the problems of high energy consumption and high operating cost of traditional biological nitrogen removal technology, domestic and foreign scholars are committed to low energy consumption and efficient biological nitrogen removal technology research. With the rapid development of microbiological research, a new type of denitrifying microorganisms have been discovered, and a new denitrification reaction mechanism of traditional denitrifying microorganisms has been proposed. This has led to the innovation of biological denitrification concepts and a number of new biological Nitrogen removal technology. Aerated biological fluidized bed, English name (AFT Biological Fluidized Tank) for short (ABFT), is a new type of biological nitrogen removal technology. This process has advantages over BAF, A / O, and MBR processes under low nutrition and low load conditions.
