Abstract

In order to reduce the pollution load from the livestock farms and to improve the water quality of the effluent in livestock wastewater, the electrolysis system is introduced. For the selection of optimal electrode, various combination of electrodes such as carbon, Al and Fe were examined. In this study, electrode material, electrolyte concentration, electrode distance, current density, and pH value were found to have significant effect on both pollutant removal efficiency and current efficiency in electrochemical oxidation process. After electrolysis for 90 min with carbon/Al, it was observed that COD, T-N, T-P and $NH_4^+-N$ of livestock waste-water were removed with $80\%,\;61\%,\;81\%\;and\;87\%$, respectively.
