Abstract
The technology of non-thermal plasma contacting with liquid has been paid attention for water treatment because of free radical generation. The advanced oxidation processes (AOPs) utilizing free radicals have been developed to decompose persistent organic pollutants (POPs). In this study, the water treatment method spraying solution into the coaxial cylinder type dielectric barrier discharge (DBD) tube is investigated. The reactor is an alumina tube with 2 mm thickness and 6 mm inner diameter. The reactor has inner powered rod electrode on the central axis of tube and outer grounded electrode on the outer wall of tube. The solution is atomized by the ultrasonic atomizer unit and introduced into the reactor. Acetic acid solution is used as POPs in this experiment. Acetic acid is decomposed in high efficiency and formic acid and oxalic acid are formed as by-products for one pass treatment.
