<p>PURPOSE: Treatment method and apparatus for sewage and wastewater are provided to effectively treating the sewage and wastewater by discharging reactor-treated water with the minimum pollutant concentration. CONSTITUTION: A treatment apparatus for sewage and wastewater comprises a reactor lower part(4), a reactor upper part(8), and a reactor processed water outlet(9). A surfactant inside the sewage and wastewater flowing into a reactor, is attached to air bubbles and oxygen bubbles generated from the reactor lower part. The bubbles attached to the surfactant are elevated to the reactor upper part by the density difference of air and the sewage and wastewater, to be re-dissolved to the surface of water.</p> |
