摘要：

A coaxial dielectric-barrier-discharge (DBD) as an ozonized water reactor system has been developed and described. It operates in the air at an atmospheric pressure. In the reactor one of the dielectric layers is flowing water. Ozone and ozonized water are generated in the same volume of the discharge. The ozone production and its dissolution in the water simultaneously occur leading to increases of the reactor efficiency. Filamentary 50 Hz DBD has been performed using up to 20 kV applied voltage. The obtained ozone concentrations correspond to the values typically suggested for the treatment of potable and wastewater. The efficiency can be further increased by addition of small amount of the oxygen in the DBD device. The periodical time dependence of the dissolved ozone concentration in Danube water is found and discussed. (C) 2004 Elsevier Ltd. All rights reserved.
