Abstract

Macrophyte plays an important role in purification of wastewater. They have capacity to improve the water quality by absorbing nutrients, with their effective root system. In this study, removal of nutrient as well as organic matter was observed by some important macrophytes i.e. Pistia stratoites, Hydrocharis dubia and Salvinia sp. indepe ndently as well as in mixed culture under the laboratory condition. The highest total nitrogen removal was observed for Pistia stratoites (86.47%) in monoculture and Salvinia sp. + P. stratoites (76.11%) in mixed culture system. Corresponding figures for total phosphorous were observed for P. stratoites (75.60%) in monoculture and Salvinia sp. + P. stratoites (71.11%) in mixed culture system. Similar result was observed for ammonia removal in both systems. Additionally, P. stratoites showed the highest removal of organic matter, in monoculture system (68.46%) where as Salvinia sp. + P. stratoites showed the highest removal of organic matter in mixed culture system (82.73 %).

수생식물은 폐수정화에 있어서 중요한 역할을 한다. 수생식물은 뿌리로 영양물질을 흡수해 수질개선을 할 수 있는 능력을 가지고 있다. 본 연구에서는 실험실에서 수생식물인 물상추, 자라풀, 생이가래를 각각의 수조와 혼합한 수조에서 영양물질 제거뿐만 아니라 유기물에 관해 관찰하였다. 단일수조에서 가장 많이 제거된 총 질소는 물상추가 86.47%이고, 생이가래와 물상추가 혼합 식재된 수조가 76.11%로 관찰되었다. 총인의 경우 단일수조에서 가장 많이 제거된 것은 물상추가 75.60%이고, 생이가래와 물상추가 식재된 수조가 71.11%로 관찰되었다. 암모니아제거의 경우도 두 개의 수조에서 유사한 결과가 나타났다. 또한 물상추 식재된 단일수조가 유기물이 가장 많은 68.46%로 제거를 보였다. 반면 혼합수조에서는 유기물의 제거가 생이가래와 물상추가 식재된 수조가 가장 많은 82.73%로 나타났다.
