Both ammonium and nitrate-nitrogen in wastewater from NOx and SOx removal facilities were converted into nitrogen gas by biological nitrification and denitrification in a submerged biofilter. The biological reaction rates were represented by the Monod equation. From the Linewaver-Burk plot, the maximum reaction rate V_<1m> and saturation constant K_<1S> of biological nitrification were caculated to 1.1×10^3mg/l・day and 0.81mg/l, respectively.V_<2m> and K_<2S> of denitrification were 1.97×10^3mg/l・day and 1.15mg/l, respectively.In the biological nitrification at pH 7.7,the required amounts of inorganic carbon, alkalinity and orthophosphoric acid were estimated.The amount of methanol added at reducing agent in denitrification was 1.1 times as much as that calculated from McCarty's equation.
