초록

In general, the electrochemical treatments, organic materials by oxidation and reduction on electrode surfaces, are regarded as simpler and faster processes for removal of pollutants compared to other wastewater treatments. In this study, The removal of Chemical Oxygen Demand (COD) of Wasted Soluble Cutting Fluids was investigated using electrochemical treatment Aluminium (Al) as electrode. Experiments were conducted to examine the effects of current density, the concentration of supporting electrolyte (NaCl, Na2SO4) on removal efficiency. Experimental data in relation to current density and concentration of electrolyte are outlined. As a result of analyzing the COD removal efficiency according to the current density without electrolyte addition, the final removal rates were 48.33% (40 A/m2), 65.63% (60 A/m2) and 78.28% (80 A/m2). As the current density increased, the COD removal rate increased. When adding electrolytes in all current density conditions, the removal rate was increased. however, Compared with before and after electrolyte addition, NaCl addition increased the average removal rate by 7.86% and Na2SO4 increased by 5.18%.
