This study emphasize on removal of organic matter by indirect oxidation process. In the electrolytic treatment, ??, ?? is producted by chloride. ??, ?? is used to organic matter oxidation. This study was conducted for the effects of organic matter oxidation, electrolysis time, electric current, ?? concentrations, and pH due to production of ??, ?? by electrolysis. Also, possibility on the second treatment by activated carbon adsorption was investigated. The results obtained were as follows : pH was rapidly increased less than 10 minutes, and was maintained after 30 minutes. When the temperature was not constantly maintained. The removal rate of TOC was increased up to 32% with the increasing of ?? concentrations and the increasing of electrolytic current. Effects of pH was not observed. When electrolysis was not carried out, adsorption constant k and 1/n were 0.017, 1.684, respectively. After the electrolysis with 1, 3, 5, 8A electrolysis, k and 1/n were 0.02, 0.022, 0.025, 0.018, 0.874, 0.518, and 0.887, 0.77, respectively. This result indicated that the wastewater included some material which is difficult to decompose. This wastewater need to pretreatment rather than independent electrolysis.
