| Abstract |
| In this study, the characteristics of milking washing water generated in dairy farms and the treatment characteristics of the single process of electrolytic oxidation using an insoluble electrode module were investigated. The results of studying the applicability of the pretreatment process for biological post-treatment through the linkage process with chemical coagulation treatment using PAC(Poly Aluminum Chloride) 17% are as follows. As a result of analyzing the water quality behavior by measuring the reaction time of the milking washing water using an electro-oxidation process, suspended solids in the form of scum accumulated on the top of the electro-oxidation reactor and could be removed. In the case of total nitrogen, ammonia nitrogen, and color, it was found that treatment efficiency was almost proportional to the electro-oxidation time. When electro-oxidation was carried out in the state of almost no suspended matter after coagulation treatment, the removal rate of ammonia nitrogen by the insoluble electrode was found to be high. When configuring the milking washing water treatment system, combining the pre-coagulation process and the electrolytic oxidation process (as a pretreatment of the biological process) allowed reduction of the load of organic pollutants by about 60% and the load of ammonia nitrogen by about 90%. |
