PCB industry occurring in process wastewater contains a large quantity of copper. Copper to form complexes with organic matter removed from the wastewater treatment plant has been fraught with difficulty. In addition, the concentration of copper is more than 1ppm of microorganisms in biological wastewater treatment has been reported that toxic effects. Therefore, in order to efficiently recover the copper complexes formed with pretreatment equipment to remove the organic matter should be focused. Photocatalytic oxidation process factors affecting the reactivity of the factors that have inhibited the formation of radicals. This is called Radical scavenger. Carbonate ions in the water that causes alkalinity (CO
) and bicarbonate ion (HCO
) to exist, these ions trap the OH radical is that acts as a scavenger. OH radicals to produce UV/TiO
AOP process with respect to the system after the addition of carbonate decomposition characteristics of wastewater DOC reduction was observed. The concentration of carbonate Na
using 0, 0.1, 0.5, 1mM changing with the decomposition of wastewater DOC removal was observed characteristics. Radical scavenger was worked effect parameter on the photo-oxidation of wastewater. Removal rate of TOC and absorbance was decreased by addition of carbonate ions and TOC removal was more sensitive.
