抄録

Model investigation was carried out to treat wastewater including oil using a swirl motion of a cylindrical wastewater bath. A mixture of air and water was injected through a centered single-hole nozzle into a water bath covered with a top oil layer. An air-water two-phase jet was generated in the bath. The jet swirled around the vertical vessel axis together with the water in the bath under a specific condition. The basic characteristics of the swirl motion such as period, amplitude, starting time, and damping time were experimentally determined in addition to the generation condition of the swirl motion. Treatment of wastewater including oil was successfully achived using a swirl motion of an ozone-wastewater two-phase jet.
