| This study was carried out to investigate the electrolysis treatabillity of livestock wastewater having high concentration of organic matters and nitrogen. Experiments were conducted to study any effects according to the operating conditions such as the current density, retention time and the ratio of added sea water. Possible optimum range for these operating variables are experimentally determined. In electrolysis process, removal efficiencies increased with the current density, ratio of added sea water and the length of retention time. With 0.4d㎡ electrode per 1L reaction volume, it was recommend the best conditions are 30% sea water, 5A/d㎡ current density and 4 hours of HRT. When livestock wastewater treatment applied electrolysis, removal efficiencies of COD, TP and TN lead to 90%, 86%, and 94% respectably. These results may indicated that electrolysis has an excellent nitrogen removal ability for treatment of livestock wastewater. |
