초록
본 연구는 다공성 소결체로 충진된 여상에 수생식물을 식재하여 오 폐수를 처리하는 기술로서, 수질오염물질의 고효율 처리를 위한 적정조건을 찾는데 연구목적을 두었다. 실험조건으로 수질오염물질(COD, T-N, T-P), 수생식물의 종류, 여재의 종류와 규격, 그리고 체류시간을 변화시켰다. 수질오염물질 중 COD는
The purpose of this study was to find the optimum condition of the high removal efficiency of water pollutant as sewage treatment technology using a filtering bed charged with porous sintering-pellet which was planted with hydrophytes. Experiment was carried out by changing concentration of water pollutants(COD, T-N, T-P), kind of hydrophyte, kinds of filtering material and size, and HRT. The result of removal efficiency was obtained as following: COD removal 73.8~87.1% for input concentration range of 50~450mg/L, T-N removal 61.3~77.3% for input concentration range of 7~124mg/L, T-P removal 89.5~99.1% for input concentration ranger of 3~27mg/L. In a comparative experiment of three kinds of hydrophyte(Iris pseudoacorus, Phragmites communis
