Natural type nonpoint pollution decrease infiltration trench
The present invention relates to a natural infiltration trench for reducing nonpoint pollution which improves a filtration effect of rain water, which is supplied from a precipitation tank to a horizontal filtration means, by increasing contact time between the rain water, which is introduced into the precipitation tank, and polymer filters by bringing the rain water, which is introduced into the precipitation tank, into contact with the polymer filters while moving the rain water from bottom to top and supplying only the filtered high quality water to the horizontal filtration means. The natural infiltration trench according to the present invention is characterized in comprising: a precipitation tank which is buried underground with an upper portion thereof opened, wherein a grating is provided on the upper portion of the precipitation tank, an inlet portion is connected with an upper portion at one side of the precipitation tank, while a rain water outlet hole is formed at an upper portion at the other side of the precipitation tank; a vertical filtration means which is vertically arranged on the other side inside the precipitation tank and which brings the rain water, which is introduced through the inlet portion, into contact with a plurality of polymer filters while moving the rain water from bottom to top to filter the rain water, and supplies only the filtered high quality water to the rain water outlet hole; an underground depression portion which is formed to be depressed left and right underground at the other side of the precipitation tank by underground excavation, wherein a drainage unit for discharging the rain water is connected with an upper portion of the other side of the precipitation tank; and a horizontal filtration means which is installed inside the underground depression portion, refilters the rain water, which is introduced to an upper portion at one side through the rain water outlet hole, and supplies the refiltered rain water underground under the underground depression portion.
본 발명은 침전조로 유입된 우수를 하부에서 상부로 이동시키면서 다수의 고분자 필터들과 접촉시켜 우수를 여과시키고 여과된 상등수만을 수평 여과수단으로 공급함에 따라, 침전조로 유입된 우수와 고분자 필터들의 접촉 시간을 길게 하여 침전조에서 수평 여과수단으로 공급되는 우수의 여과 효과를 향상시킬 수 있도록 하는 비점오염저감을 위한 자연형 침투도랑에 관한 것으로, 상부가 노출되게 지중에 매설되고, 상부에는 그레이팅이 구비되며 일측의 상부에는 유입부가 연결되고 타측의 상부에는 우수 배출구가 형성되는 침전조와; 상기 침전조의 내부 타측에 수직으로 구비되어 상기 유입부로 유입된 우수를 하부에서 상부로 이동시키면서 다수의 고분자 필터들과 접촉시켜 우수를 여과시키고 여과된 상등수만을 상기 우수 배출구로 배출시키는 수직 여과수단과; 상기 침전조의 타측인 지중에 지중 파기를 통해 좌우 방향으로 함몰되게 형성되고, 타측의 상부에는 우수를 배출하는 배수부가 연결되어 있는 지중 함몰부와; 상기 지중 함몰부의 내부에 설치되어 상기 우수 배출구를 통해 일측의 상부로 유입되는 우수를 재차 여과시켜 지중 함몰부의 하부의 지중으로 침투시키는 수평 여과수단;을 포함하는 것을 특징으로 한다.
