Description
수생식물은 오래 전부터 하수처리에 활용되어 왔으며, 주로 활용되는 수생식Aquatic plants have been used for sewage treatment for a long time.
물로는 성장이 빨라 수중의 질소 및 인 성분의 제거에 효과적으로 알려진 부레옥잠Water hyacinth is known to be effective for the removal of nitrogen and phosphorus from the water due to its rapid growth.
을 비롯한 미나리, 갈대, 마름 등이다. 종래에는 이러한 수생식물을 생활하수가 흐Including buttercups, reeds, dry. In the past, these aquatic plants could not flow
르는 하천주위에 재배함으로서 하수중의 유기 및 무기성 오염물질을 제거하는 정도Le is cultivated around rivers to remove organic and inorganic contaminants from sewage.
였다. 그러나 본 발명특허에서는 부레옥잠 재배조에 공기를 공급함으로서 부레옥잠 It was. In the present invention, however, water is supplied by supplying air to the water hyacinth cultivation tank.
의 뿌리 및 부레옥잠 재배조에 서식하는 호기성 미생물을 이용하여 BOD를 Aerobic microorganisms in the roots and water hyacinth cultivation
제거하고, 질소 및 인 성분은 부레옥잠의 영양분으로 흡수 제거한다. 그리고 부레옥잠 재배조에서 성장한 미생물 및 생활하수중의 SS는 침전지에서 제거된다.The nitrogen and phosphorus components are absorbed and removed by nutrients of water hyacinth. Microorganisms grown in water hyacinth cultivation plants and SS in domestic sewage are removed from the sedimentation basin.
부레옥잠 재배조 및 침전지에서 제거되지 않은 BOD 및 SS성분은 모래여과 및 활성탄 여과층에서 제거하며, 질소 및 인성분은 양이온 및 음이온교환수지에서 제거하도록 한다. BOD and SS components not removed from the water hyacinth cultivation tank and the settling basin are removed from the sand filtration and activated carbon filtration layers, and nitrogen and phosphorus components are removed from the cation and anion exchange resin.
본 발명은 일일 생활하수 발생량이 작아 하수처리장 설립이 어려운 인구 1만미만의 소도시에서 발생되는 생활하수를 자연 친화적 공법인 수생식물을 이용한 처리공법이다. 하수처리에 수생식물(부레옥잠)을 이용함으로서 주변 경관과의 미적 조화를 이루고 하수처리비용을 크게 저감시킬 수 있다. 그리고 후단에 여과층(모래+입상활성탄+이온교환수지)을 둠으로서 기존의 하수처리장보다 양호한 방류수 수질을 얻을 수 있다.The present invention is a treatment method using aquatic plants, which is a natural friendly method for living sewage generated in small cities of less than 10,000 population difficult to establish a daily sewage treatment plant is small. By using aquatic plants (water hyacinth) for sewage treatment, it is possible to achieve aesthetic harmony with the surrounding landscape and greatly reduce the cost of sewage treatment. In addition, by providing a filtration layer (sand + granular activated carbon + ion exchange resin) at the rear end, it is possible to obtain better effluent water quality than the existing sewage treatment plant.
본 발명에 사용된 소규모로 제작된 실험장치도면을 그림 1에 나타내었다. A small scale experimental apparatus drawing used in the present invention is shown in Figure 1.
