Around the rainwater penetration tube 1 according to the present invention is installed 15 rainwater outflow hole 4 in the diameter circumference of the rainwater penetration tube 1 in the 15 ~ 20mm standard and the vertical distance of the rainwater outflow hole 4 is approximately It should be 65mm (approximately 50 rainwater outflow holes are provided if the diameter of rainwater penetration tube is 400mm). The rainwater penetrating bucket (1) is installed in the water permeable sheet (6) to prevent the introduction of contaminants from outside.

Rainwater penetration container 1 according to the present invention is installed in connection with the rainwater penetration side opening 20 or rainwater penetration tube 10 for the purpose of reducing the excellent runoff of the surrounding area, and also the non-point source and heavy metal of the initial excellent It also has the ability to remove it.

The non-point source removal device 14 according to the present invention is installed in the rainwater penetration container 1 as shown in FIG. 3 and is designed to pass through the nonpoint source removal device 14 when the initial rainwater enters the rainwater penetration container 1. have. The non-point source removal apparatus 14 is selected according to the shape (angle, circle) of the rainwater penetration tube 1 in a rectangle and a circle as shown in FIGS. 4A and 4B.

The specification of the non-point source removal device 14 is designed to be slightly smaller than the internal standard of the rainwater penetrating bucket 1 so that it does not interfere with attachment and detachment. The material of the non-point source removal apparatus 14 is glass fiber mat (GMT), synthetic resin, stainless steel, or the like, and uses a material that does not deform or rust. In the non-point source removal device 14, a filter medium for removing non-point source or heavy metal in the initial rainwater is built-in, and as the filter medium, materials having high interfacial activity such as black shell (12) or activated carbon (13) are stacked.

When explaining the rainwater infiltration through the rainwater (1) the initial excellent non-point source removal function in more detail. The initial rainfall is less than 10mm of rainfall and has a rainfall frequency of around 80% per year. The present invention has been developed for the purpose of removing the non-point source and heavy metals in the initial rain, taking note that the initial rain occupies such a small amount of rainwater and a high frequency.

The initial rainwater is introduced into the rainwater penetration tube 10 through the rainwater penetration side opening 20, and the rainwater penetration side opening 20 and the rainwater penetration tube 10 are rainwater outflow holes up to a predetermined height from the bottom thereof. Since the rainwater penetrating side opening 20 and the rainwater penetrating tube 10 are discharged, the initial rainwater is collected at the bottom of the rainwater penetrating side opening 20 and the rainwater penetrating tube 10, and the initial water collected is collected. Rainwater flows into the rainwater penetrating barrel 1 through the inclined surface (2 to 3%) of the rainwater penetrating side opening 20 and the rainwater penetrating tube 10.

However, when the rainfall is more than 10mm / hr, the rainwater outflow penetrating pipe 3 immediately flows through the m₁ curve of FIG. In case of heavy rainfall, the head of the rainwater penetrating pipe (10) can fill up to 80 ~ 90%, and the crushed rock layer around the rainwater penetrating device becomes saturated, and some of the rainwater penetrates and some of the rainwater penetrates in the rainwater penetrating pipe (10). The non-point source and heavy metals are removed from the next rainwater penetration tube (1).

The initial rainwater introduced into the rainwater penetration tube 1 according to the present invention shows an active surface active effect in the filter medium layer while flowing into the filter medium layers 12 and 13. The interior of the filter media layers 12 and 13 is porous and there are many micropores, so when water enters the water passes through, and the nonpoint source and heavy metal are adsorbed in the pores due to the surface active effect. When there is no rain, the nonpoint source and the heavy metal are immobilized in the pores of the filter media layers 12 and 13. The filter medium used was found to be able to be reused about 5 to 10 times when the non-point source and heavy metals were removed by hot or cold treatment.

The thickness (k of FIG. 4A and FIG. 4B) of the filter media layers 12 and 13 is 100-120 mm, respectively, suitably 200-240 mm in total. This means that the height of the filter media layers 12 and 13 should be lower than that of the rainwater infiltration tube 2 and the rainwater infiltration tube 3 of the rainwater penetration tube 1, and if the filter media layers 12 and 13 are too thick, the rainwater penetration It is possible to reduce the penetration effect of the barrel (1), the rainwater penetration side opening (20) and the rainwater penetration tube (10) connected to the rainwater penetration tube (1), if the filter medium layer (12, 13) too thin, non-point source And the removal efficiency of heavy metals is lowered.
