This study was carried out to investigate the effect of photocatalysis using TiO₂ and UV applied for the COD reduction of wastewater in linerboard mill. Trials were done to obtain the optimum addition amounts of TiO₂ and H₂O₂ to the wastewater and find an appropriate pH condition for photocatalysis on TiO₂ for degrading COD. The photocatalytic reaction was applied to the wastewater collected after secondary activated sludge treatment in WWTP of linerboard mill. The optimum application of photocatalysis reaction was obtained under the addition conditions of 2 g/L of TiO₂ and 200 ㎎/L of H₂O₂ at pH 3.0, respectively. The removal efficiency of SCODCr by photocatalytic treatment was 86.4 % and higher than Fenton treatment in which removal efficiency was 67.4 %. It was concluded that the photocatalytic process using TiO₂ and UV could be applied to the wastewater treatment in linerboard mill and also to the dramatic drop-off in NBDCOD load from wastewater of tertiary treatment in WWTP.
