Abstract
There are serious problems of water pollution in the world. Recently, the conventional chemical treatment has been replaced by the water treatment system using plasma・ In this study, a method for decomposing organic compound by spraying solution as mist into reactive plasma directly is investigated,using mist flow plasma reactor originally developed. Reactive plasma is generated by dielectric barrier discharge (DBD) on tube inner wall. The atomized solution in micro size is introduced into the mist flow plasma reactor and is treated by ozone, free radicals and ultraviolet rays. Dissolved chemical species like H2O2, reactive oxidation species, O3, NO3-, pH, and conductivity is measured as liquid property. In addition, the decomposition characteristics of this method are experimentally clarified through decolonization experiments of methylene blue solution.
