| Abstract |
| This study was carried out to propose effective management methods of pumping & drain station for agricultural non-point pollution reduction, The test facility is located in Changnyeong-gun, and the existing operation of the test facility is to open the drain door at all times. So the collected water containing pollutants is discharged into the mainstream and nak-dong river, The operating range of the test facility is 5 m(±0.3) and recall water flows into the pumping & drain station during 2 hours after water supply interruption. Also it investigated effluent reduction load BOD 16.2 kg/day, T-N 28.064 kg/day and T-P 1.950 kg/day. But the efficient management method can be applied only dry seasons. Because when it was rains, there is concern about flooding in upstream farmland. As a result of this study we proposed the possibility of an efficient operation method, but continuous research is needed for the extension application. |
