    • A wastewater treatment apparatus comprising a denitrifying reactor and a denitrifying filtration tank and a wastewater treatment method using the wastewater treatment apparatus are provided to secure a stable quality of the effluent by reducing a nitrogen content of final effluent during wastewater treatment, thereby preventing nitrogen contained in the effluent from having a bad influence on an ecological environment of a water system. A wastewater treatment apparatus comprises: a first sedimentation tank(10) into which wastewater is flown, and in which a settling process of wastewater is performed; a bioreactor including an aerobic tank(40) for nitrifying effluent of the first sedimentation tank using microorganisms; a second sedimentation tank(50) for settling a microorganism sludge of the bioreactor; a denitrifying reactor(60) which contains effluent of the second sedimentation tank, and in which carriers are embedded to denitrify the effluent; and a denitrifying filtration tank(70) in which a filter medium is contained to remove suspended solids contained in effluent of the denitrifying reactor, and which removes residual nitrates of the effluent. The carriers are waste tire-processed fluidized bed carriers or polyurethane carriers. The filter medium has a filtration ratio of 50 to 100 m^3/m^2.d. The bioreactor additionally includes an anaerobic tank(20) and an anoxic tank(30).
