Livestock wastewater has a high concentration of organic matter and particularly a very high concentration of substances that lead to eutrophication, making it a serious point source of pollution polluting water resources such as rivers and lakes. In this study, a study was conducted on the evaluation of the third treatment characteristics of livestock wastewater through a water treatment electrolysis device using a carbon nano tube(CNT) electrode. The electrolysis method not only removes organic matter(biochemical oxygen demand, chemical oxygen demand, etc.), but also has high removal efficiency of ammonia nitrogen, is a very economical method because the device is inexpensive and the contact time is short. As a result of the study, the higher the pollution degree of wastewater was, the higher the current intensity according to the applied voltage. According to the amount of dissolved pollutants, it was found that the amount of current increased close to the second-order polynomial with increasing voltage. In addition, through lab-scale experiments, it was shown that the higher the applied voltage, the higher the efficiency of organic matter and nitrogen-based treatment. When the applied voltage was 8V and 40 minutes elapsed, the chemical oxygen demand(COD) removal rate was 62% and the total nitrogen(T-N) removal rate was 31%, showing an effect of improving water quality through electrolysis.
