微細気泡オゾンを用いた切削油に対する水処理

抄録

Ozone has a strong oxidation capability. It is often used for water treatment system. However, ozone has the demerit that it is difficult to be dissolved in water. Therefore, we used micro- bubble in order to dissolve ozone in water. The diameters of the micro- bubbles are less than 50μm. The micro- bubble has features that are slow ascent rate and high inner pressure. In this study, we conducted a water treatment for cutting oil using the micro- bubble ozone in order to improve the efficiency of the ozone treatment. The experiment shows BOD increased by the micro- bubble ozone.
