Characteristics of high concentration. yield multi discharge type ozonizer for dyeing water treatment

In this paper, high concentration yield multi-discharge type ozonizer (MDO) of new discharge type using superposed silent discharge was designed and manufactured, MDO can be consisted with 3 kind of multi discharge type ozonizer (MDO) in accordance with power supply method that supplying power, which has 180[$^{\circ}$] phase difference, to 3 electrodes and double gap. At the moment, discharge characteristics and ozone generation characteristics of each MDO were investigated in accordance with quantity of supplied gas, the number of MDO, and the shapes of each MDO. In result, ozone generation characteristics of 17185[ppm] and 783[g/kWh] were obtained, and when ozone of 17185 [ppm] was in contact with dyeing water waste, decolorization characteristics was excellent, so it confirmed that MDO could be used as water environment improvement facility.
