EMBODIMENT OF THE INVENTION Hereinafter, the natural vegetation type nonpoint source filter apparatus of this invention is demonstrated, referring drawings for based on the preferable embodiment.

Natural vegetation type non-point source filtration device of the present invention is basically the same as the contents shown in Figs.

The structure 08 of the tree filtration box 06 is installed on the side of the road 16, the park, the sidewalk 18, etc., and is made of concrete or aggregated wood. When installed on the side of the road 16, the standard is manufactured to almost the same size as the green area width (usually 1 ~ 2m). The tree filtration box 06 is manufactured in a box shape with the hygroscopic plant 10 at the center.

In the filtering box of the tree filtration box 06, three types of soil layers are formed so that the hygroscopic plants 10 such as trees can grow well and rainwater can be filtered.

The top layer is composed of a side layer of soil or humus (03) and supplies nutrients that plants can grow, and Humic contained in the side layer has a function of adsorbing heavy metals. This soil layer is the root 10-1 of the hygroscopic plant 10 can adsorb non-point pollutants and heavy metals, thereby acting as a filtration and media. The coarse soil or humus layer 03 is about 400 mm thick.

The coarse soil layer (04) is composed of sand and wood-chips that can filter water and humus that can provide nutrients to plants. Sand and wood-chips are excellent filter media for adsorption and filtration of nonpoint sources and heavy metals. The granulated soil layer 04 is composed of about 300 mm thick.

The filtration layer (05) is composed of about 300 mm thick using residue and blast furnace crushed stone or high loose lag. Jangal and high-loss lag can filter water well, and high-loss rag has high surface activity, so it has the property of adsorbing or filtering nonpoint sources such as heavy metals in the porous interior.

Under the filter layer (05), a 300 mm thick silt layer (05-2) containing silt and sand in a ratio of about 6: 1 is installed in order to prevent the rapid outflow of rainwater. -2) Root to the upper soil layer so that it can grow.

Rainwater inflow and outflow paths in the tree filtration box 06 are as follows.

Rainwater that falls on the road 16, sidewalks, and parks 18 is filtered while penetrating into the soil layer through the rainwater inflow hole (01. 150x450 mm) and the screen grid (02. stainless steel 150x450 mm) of the tree filtration box 06. do. Unsaturation permeability coefficient (Ko) of the combined soil layer (03), coarse soil layer (04) and filtration layer (05) is applied at 1.0x1.0 ^-3 cm / s, and the unit penetration is measured at about 3.5m3 / hr. do.

Rainwater introduced into the tree filtration box 06 passes through the rainwater outflow pipe (07-1) installed in the granulated soil layer (04) and the filtration layer (05) when it is unsaturated permeate, and the first filtered rainwater penetrates the pollen (11). Flows into).

The tree filtration box 06 according to the present invention is overflowed to the overflow pipe (07. By Pass) when the amount of rainwater flowing from the road surface 16 due to the continuous rain or heavy rain is greater than the speed of passing through the three-stage soil layer. It is designed to be overflowed. The overflowed rainwater flows into the rainwater penetrating device 13 and penetrates into the ground or moves to another area, thereby preventing the rainwater from leaking and reducing flooding in the surrounding area.

The rainwater penetration device 13 may use a rainwater penetration tube having a rainwater discharge hole around the pipe, and the rainwater penetration device having a non-point source removal function disclosed in Patent Application 10-2011-0007624 filed by the present applicant. Preference is given to using.

When the water is dried in the tree filtration box 06 during the dry season, the water is also dried by the penetrating pollen 11, and is automatically controlled by the signal of the electromagnetic sensitive sensor 28 that detects the water dry of the penetrating pollen 11. By operating the submersible motor 24 and the drain pipe 26, the rainwater stored in the rainwater storage penetrating tank 14 is automatically pumped and supplied to the penetrating pollen 11, passing through the rainwater outlet pipe 07-1 to the tree filtration box. Water is supplied to (06).

The structure 08-1 of the penetrating flower pot 11 according to the present invention is made of precast concrete, aggregated wood, or the like so that rainwater does not leak.

The penetrating pollen 11 receives rainwater from which the non-point source is removed from the tree filtration box 06, where a suitable environment is formed so that aquatic plants and microbes can inhabit.

Rainy season is used for the rainy season, and the rainwater stored in the rainwater reservoir penetrating tank 14 is supplied by the automatic control device 23.

The soil layer of the penetrating pollen (11) is composed of three layers of soil so that aquatic plants and microbes can inhabit and rainwater can be filtered.

The top layer is composed of a foliate or humus layer (03-1) and supplies nutrients that plants can grow, and Humic contained in the foliage has a function of adsorbing heavy metals. In this soil layer, root plants such as apiaceae of purified plants can adsorb nonpoint pollutants and heavy metals, and thus act as filtration and media. The coarse soil or humus soil layer 03-1 is formed to a thickness of about 400 mm.

The granulated soil layer (04-1) is composed of humus soil that can provide nutrients to plants and sand and wood-chip that can filter water. Sand and wood-chips are excellent filter media, and have excellent performance in adsorbing and filtering nonpoint sources and heavy metals. The granulated soil layer 04-1 is formed to a thickness of about 300 mm.

The filtration layer (05-1) is formed to a thickness of about 300 mm by using residue and blast furnace crushed stone or high loss lag. Jangal and high-loss lag can filter water well, and high-loss rag has high surface activity, so it has the property of adsorbing or filtering nonpoint sources such as heavy metals in the porous interior.

The inflow and outflow paths of rainwater from the penetrating pollen 11 are as follows.

Rainwater falling on the road 16, sidewalks, and parks 18 penetrates into the combined soil layer composed of three layers through the rainwater inflow hole 01-1 and the screen lattice membrane 02-1 of the infiltration pot 11. do. Unsaturation permeability coefficient (Ko) of the combined soil layer (03-1), coarse soil layer (04-1) and filtration layer (05-1) is applied at 1.0x1.0 ^-3 cm / s. It is measured at 3.5 m 3 / hr.

When the introduced rainwater becomes unsaturated permeate, it passes through the rainwater outflow pipe (07-1) installed in the granulated soil layer (04-1) and the filtration layer (05-1) to pass through the tree filtration box (06). do.

In addition, the rainwater introduced from the tree filtration box 06 is supplied to the purified plants and plants of the penetrating pollen 11 and natural circulation and filtration.

When the amount of rainwater flowing in is large, it is designed to flow into the rainwater reservoir penetrating tank 14 through the rainwater discharge pipe 07-2.

The present invention is based on distributed rainwater management based on the natural circulation principle of filtration, infiltration, storage and use of rainwater resources.

That is, according to the present invention, the rainwater that falls on the road 16, the sidewalks, and the park 18 is filtered through the tree filtration box 06 and the permeate pollen 11 to remove the nonpoint source in the initial rainwater, and the filtered rainwater is underground. It is stored in the rainwater reservoir penetrating tank (14) buried in the ground, and by reducing the outflow of rainwater by infiltrating into the ground and can use a variety of stored rainwater, and in the case of continuous rainfall or heavy rains to overflow the rainwater into the rainwater penetration device (13) It is a typical decentralized rainwater management system that can reduce rainwater spillage and prevent flooding by inducing rainwater into areas with high penetration and permeability.

The present invention develops a low-cost, eco-friendly distributed rainwater management optimization (BMPs) model by organically linking the tree filtration box (06), the penetrating flower (11), the rainwater storage osmosis tank (14), and the rainwater penetration device (13). At one point, there are technical features.
