Abstract

PURPOSE: To treat effectively without generating clogging or the like by filling hollow porous spheres into a denitration tank.
CONSTITUTION: A waste water inflow pipe 3 is provided to an upper portion of a denitration tank 2 of a denitration apparatus 1 and waste water is poured into a denitration tank 2. The treated water is flowed out by providing a treated water flow-out pipe 4 to a lower portion of the said tank 2. If necessary, a recycle pipe 6 equipped with a recirculating pump or a floating preventing net 5 is provided. Moreover, an exhaust pipe 7 for exhausting generated nitrogen gas or the like is provided to an upper portion. As a filter material, hollow porous spheres 8 are filled in a denitration tank 2. The density of hollow porous spheres is appropriately determined according to the selection of a material thereof, a wall thickness, pore numbers and a size.
