Abstract |
The objective of this study was to remove organics and color in livestock wastewater using coagulation and Fenton oxidation process. After coagulation process as 1^(st) treatment, organics in 1^(st) treatment water were removed by using OH radical produced in Fenton oxidation process. Removal efficiencies of COD_(Mn) and color were 87.2% and 95.7% separately. At that time, the ratio of Fe^(2+)/ H₂O₂ was 0.8∼1.0, and range of reaction pH was effective at the pH of 3.5∼3.8. The Reaction time of 120min more than 60min or 90min was sufficient in Fenton process. Removal efficiency of organics was higher two- or multi-stage treatment than one-stage treatment. |
