전기분해공정을 이용한 염색 폐수처리에 관한 연구 = A Study on the Dye Wastewater Treatment using Electrolysis Process

다국어 초록 (Multilingual Abstract)

Dye wastewater was treated with an electrolysis process. The electrochemical technology using C/C, Fe/Fe, Al/ Al electrodes was investigated. In this study, electrode material, electrode concentration, electrode distance, current density, and pH value were found to have significant effect on COD and color removal efficiency in electrolysis process. After electrolysis for 60min with AV Al, COD removal efficiency was 57% and color removal efficiency was 100%, respectively.
COD removal efficiency with electrode distance was 62% in 3cm after electrolysis for one hour. Removal efficiency of color was 100%. It was explained by the activation of electrooxidation and electrocogaulation.
The removal efficiency of COD with current density seemed to be 55% in 40mN cm² after one hour reaction and color removal efficiency was 100%.
The removal efficiency of COD with electrode concentration was 62% in NaCl 4000ppm after one hour reaction and color removal efficiency was 100%.
The highest removal efficiency of COD and color with variation of pH was pH 5.0. The removal efficiency of T-N, NH₄⁺-N, color was 38%, 82%, 90% after 40min reaction.
The optimal conditions of the electrooxidation process to treat the dye wastewater in this study were as follows current density(40mA/cm2 ), electrode distance(3.0cm), pH value(5.0) and Al/ Al electrode.
