A cylindrical-anode wetted-wall corona discharge reactor was used to degrade phenol in water. Acetic acid and some aromatic intermediates, such as resorcinol, pyrocatechol, hydroxinon, and 1,4-benzoquinone, were detected as by-products. From the concentration change with time of these by-products, the aromatic by-products were considered to be converted to relatively stable acetic acid before the total carbons were mineralized. By using the present method, TOC and COD were reduced to negligible levels. The energy efficiency of this reactor was higher than that of the previous plate-anode reactor, and also than that of other reported physico chemical techniques such as pulsed discharge or photocatalysis.
