摘要：

A laboratory scale upflow biological aerated filter (BAF) packed with a porous expanded polyurethane medium was developed to nitrify ammonium to nitrite selectively. Greater than 95% removal of ammonium was achieved up to 2 kg NH4+-N m(-)3 d. NO2--N was accumulated up to 60% of the total (NO2- + NO3-)-N when oxygen was limited.
