초록
10년 전부터 논농사가 중단되고 농업배수와 생활하수가 유입하여 식생이 번성한 습지에서 수질개선 효과를 측정하였다. 습지의 체류시간이 평균 1.2일로 매우 짧음에도 불구하고 SS와 질소의 제거효과는 높게 나타났다. 질산성질소의 제거효율은 평균 유입부하량의 61.4% (26.8 g/m
The water clarification efficiency was examined in a shallow wetland where dense vegetation was formed naturally in an abandoned paddy field. And, also two enclosure experiments were carried out to measure the effects of materials exchange between sediment and the overlying water with the existence of vegetation and accumulated litter. The hydraulic retention time of wetland was regulated in 1.2 day. The removal rates of SS (56%) and
