The world is faced with serious problems of water pollution. Recently, conventional chemical treatment has been replaced by a water treatment system using plasma. In this study, using a newly developed mist-flow plasma reactor, a method for decomposing methylene blue by directly spraying solution as mist into reactive plasma was investigated. Reactive plasma is generated by dielectric barrier discharge (DBD) on the inner wall of a tube. An atomized solution containing micro-sized droplets was introduced into the mist-flow plasma reactor and treated by ozone, free radicals and ultraviolet rays. Dissolved chemical species such as H2O2, reactive oxidation species and O3 as well as NO2-, pH, and conductivities are measured as liquid properties. In addition, the decomposition characteristics of this method were experimentally clarified through decolorization experiments of methylene blue solution.
