Description
본 발명은 연못이나 호수에 식물체가 식재된 부체를 띄워 담수호의 수질을 환경 친화적으로 정화토록 하기 위한 인공식물섬을 이용한 수질정화 장치에 관한 것으로, 특히 식물체에 의한 자연정화 능력에만 의존치 않고 미생물의 증식을 위한 서식 및 성장 조건을 마련하여 식물체 흡입에 의한 영양염류의 제거 뿐 아니라 미생물 분해에 의한 각종 유기물까지도 처리할 수 있도록 하여 수처리 효과를 높일 수 있도록 한 것이다.The present invention relates to a water purification device using an artificial plant island to float the floating planted plants in ponds or lakes to clean the water quality of freshwater lakes in an environmentally friendly manner. By providing habitat and growth conditions for growth, it is possible not only to remove nutrients by inhalation of plants, but also to treat various organic substances by microbial decomposition, thereby improving water treatment effect.
종래의 인공식물섬은 호수나 하천 등의 담수호에 갈대나 청포 등 수질정화능력이 탁월한 식물체를 인공부도에 식재하여 띄어지게 함으로서 주변 경관을 해치지 않으면서도 식물체의 뿌리를 통하여 식물체의 성장에 필요한 영양물질(N, P)을 흡수토록 함으로서 부영양화를 초래하는 영양물질(N, P)을 식물체의 자연정화 능력을 이용하여 친환경적으로 처리할 수 있도록 한 것이었다.Conventional artificial islands are planted with artificial waters such as reeds and blue water in freshwater lakes such as lakes and rivers, and floated on artificial buoys to nutrient substances necessary for the growth of plants through the roots of plants without harming the surrounding landscape. By absorbing (N, P), nutrients (N, P), which cause eutrophication, can be treated in an environmentally friendly manner using the natural purification ability of plants.
그러나 이때 식물체가 흡수하는 물질은 수질오염대상 물질 중의 일 부분인질소(N)와 인(P) 뿐이어서 부영양화 방지 이외의 수처리 효과는 크게 기대할 수 없는 것이었다.However, at this time, the only substances absorbed by plants are nitrogen (N) and phosphorus (P), which are a part of the water pollutants, and water treatment effects other than eutrophication were not expected.
또한 인공부도에의 식물체 식재 매질로서는 친환경적이면서도 부체로서의 요건을 고려하여 천연물질인 야자섬유와 부식토 등이 이용되고 있는 것으로, 이때 사용되고 있는 매질은 식물의 성장 요건으로서의 기능만이 가능할 뿐 자체적인 정화능력이 없고 오히려 그 자체가 유기물로서 수중에 분해되면서 수질오염을 가중시키는 결과를 초래하고 있다.In addition, as a planting medium for artificial bushings, natural materials such as palm fiber and humus soil are used in consideration of environmentally friendly and floating requirements. The medium used here is only capable of growing as a plant's growth requirement and has its own purification ability. Rather, it decomposes itself into water as an organic substance, resulting in water pollution.
따라서 인공식물섬만으로는 수질오염원의 일부만이 제거할 뿐이어서 수처리 효과를 크게 기대할 수 없었던 것이다.Therefore, only artificial plant islands can remove only a part of the water pollution source, so the effect of water treatment could not be greatly expected.
따라서 본 발명은 상기한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 본 발명의 목적은 인공식물섬에 식재되어진 식물체에 의한 일부 오염물질의 제거뿐 아니라 미생물의 증식을 위한 서식 및 성장 조건을 마련하여 수질오염 대상물질의 대부분을 처리할 수 있도록 하고자 함이다.Therefore, the present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to provide a habitat and growth conditions for the growth of microorganisms as well as the removal of some contaminants by plants planted in artificial plant islands The aim is to be able to handle most of the water pollution target substances.
이를 위하여 본 고안은 인공식물섬의 식재 매질로서 다공성소결체를 사용하여 미생물의 부착성장을 위한 서식 장소로 제공토록 하고, 수압차를 이용하여 수계 저면의 심층수를 끌어올려 수압차에 의한 수계 내부에의 산소 공급 및 순환 작용으로 미생물의 성장을 활발히 유지시킬 수 있도록 하기 위한 수압차 순환폭기장치를 장착시킨 수질정화 장치를 제공하고자 한 것이다.To this end, the present invention provides a planting site for microbial adhesion growth using porous sintered body as a planting medium for artificial plant islands, and uses a hydraulic pressure differential to raise the depth of the bottom surface of the water system. An object of the present invention is to provide a water purification apparatus equipped with a hydraulic pressure circulation aeration device for actively maintaining the growth of microorganisms by oxygen supply and circulation.
