<p>An ozone generator (24) adapted to form ozone, an atomization nozzle (27) provided in an upper portion of the interior of a sewage water treating discharge water treatment tank (16) and adapted to mix ozone with water and atomize a resultant mixture, a compressor (25) adapted to send the ozone formed by the ozone generator (24) to the atomization nozzle (27), and a pump (26) adapted to supply water to the atomization nozzle (27) are provided, the surface of the sewage water being covered with the ozone and fine water particles sprayed from the atomization nozzle (27) into the interior of the discharge water treatment tank (16), highly active hydroxy radicals being formed by the ozone and water molecules of the fine water particles to oxidize odor components, whereby the diffusion of odor to the outside of the discharge water treatment tank (16) is suppressed.</p> |
