| Abstract |
In this research, an wasted washing machine was remanufactured to a sequencing batch reactor(SBR) and investigated for treating swine wastewater with it. This SBR system was operated for removing COD, ammonia, and suspended solid, that were the major pollutants in animal wastewater. Aerobic and anoxic conditions after FILL were applied intermittently for effective removal of nitrogen. SETTLE and DRAW modes were followed by the complete aerobic and anoxic REACT. The total volume of the SBR was 75 liters, while the working volume in a cycle was 35 liters. When the final operating strategy of the SBR was FILL/REACT/SETTLE/DRAW of 0.5/10/1/0.5 hr, the removal efficiencies of TCOD_(Cr), NH₄-N, and T-N were 95, 98, and 85%, respectively. Finally, this SBR system can handle 10(based on 70㎏) pigs effectively. |
