Zusammenfassung: | The present invention relates to a river water purification apparatus using a nature flow-type gravel contact oxidation waterway and a multi-stage grassed waterway, which can prevent eutrophication of river water by allowing passage of the river water and fine soil to some extent through a gravel contact oxidation waterway, and can effectively purify the river water by allowing the river water to pass through a grassed waterway. The river water purification apparatus using a nature flow-type gravel contact oxidation waterway and a multi-stage grassed waterway according to the present invention includes: a gravel contact oxidation waterway installed across a river; and a grassed waterway provided along a riverside at a rear end of the gravel contact oxidation waterway, wherein the gravel contact oxidation waterway includes a plurality of unit gabions arranged in multiple rows in a river flow direction and stacked in multiple stages in a vertical direction, and a unit gabions for purification provided between the unit gabions to filter pollutants in the river water and decompose organic pollutants in the river water through aerobic microorganisms.
본 발명은 자갈접촉산화수로를 통해 하천수와 미세토사의 통과가 일정 수준 가능하도록 함으로써 하천수의 부영양화를 방지하고 하천수가 식생수로를 통과하도록 함으로써 하천수를 효과적으로 정화시킬 수 있는 자연유하식 자갈접촉산화수로 및 다단식 식생수로를 이용한 하천수 정화장치에 관한 것으로서, 본 발명에 따른 자연유하식 자갈접촉산화수로 및 다단식 식생수로를 이용한 하천수 정화장치는 하천을 가로지는 형태로 설치되는 자갈접촉산화수로; 및 자갈접촉산화수로 후단의 천변을 따라 구비되는 식생수로;를 포함하여 이루어지며, 상기 자갈접촉산화수로는, 하천 흐름 방향으로 복수열로 배치됨과 함께 수직 방향으로 복수단으로 적층되는 복수의 단위돌망태와, 단위돌망태 사이에 구비되어 하천수의 오염물질을 여과함과 함께 호기성미생물을 통해 하천수의 유기오염물질을 분해하는 정화용 단위돌망태를 포함하여 구성되는 것을 특징으로 한다. |
