The characteristics of electrochemical oxidation of textile wastewater by RuO$_2$/Ti electrode were studied. Operation parameters such as current density, electrolyte concentration, organics concentration in solution, types of electrolyte, and material of anode were selected and their effects on COD removal, color removal, and current efficiency(EOI) were investigated. COD removal showed a first-order reaction kineties. COD and color removal of textile wastewater were proportional to current density and electrolyte concentration, respectively, but disproportional to organics concentration. Especially, COD removal color removal, and current efficiency were highly improved by appling electrolytes containing Cl$^{[-10]}$ ions such as NaCl and KCl. In addition, RuO$_2$/Ti anode was relatively more effective than Pt/Ti anode for COD removal, color removal, and current efficiency.
