Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a non-point pollution abatement facility having a vegetation channel,

The present invention relates to a non-point pollution abatement facility having a vegetation channel, and more particularly, to a non-point pollution abatement facility having a vegetation channel, and more particularly, to a method and apparatus for reducing non-point pollutants in rainwater runoff through a vegetation channel and efficiently collecting water for garden water such as landscape water and fire- And a non-point pollution abatement facility having a vegetation channel.

Nonpoint source pollution refers to drainage from farm drainage, mine waste water, livestock wastewater from small scale livestock facilities, living sewage or forest in rural areas without sewerage, and these pollutants are relatively dependent on natural treatment due to less contribution of pollution.

Non-point pollutants are mainly pollutants that run out along with surface rainfall runoff when they are exposed to rain. These include fertilizers, pesticides, soil sprinkling plants, housing spills, traffic pollutants, dust and garbage in urban areas, Residues, and air pollutants that have fallen on the surface of the earth.

Therefore, rainwater (rainwater runoff) containing all pollutants is actually the main nonpoint source. Since non-point pollutants usually flow out with a lot of rainfall, there is a large difference between daily and seasonal emissions, and it is difficult to forecast and quantify, and it is affected by weather conditions, geology, and topography which are difficult to manure.

The vegetation waterway is a waterway with vegetation. It captures the rainwater runoff from the drainage area, reduces and transports nonpoint pollutants, and performs the function of preserving water quality.

Generally, the conventional non-point pollution source management method is classified into a physical method of installing and managing various processing facilities and structures and a non-physical method of applying land use regulation.

In the case of the former, the permeation type requiring a lot of maintenance such as infiltration and infiltration trenches, the vegetation type such as the reservoir type, vegetation filtration type, and vegetation water type such as artificial wetlands and reservoir ponds requiring relatively large site, There are sewage treatment types such as facilities.

These are relatively difficult to regulate non - point pollution sources, but they are difficult to accommodate land with a large installation area in Korea where the cost is high and the necessary area for installation of treatment facilities is a major limiting factor in selecting treatment facilities.

In the latter case, the cost is low, but the efficiency is low and the possibility of complaints is high.

In addition, once non-point pollutants are introduced into surface water or ground water, management is difficult. As the non-point pollutant treatment is far from the pollutant source, the treatment becomes difficult and the treatment cost increases. However, the conventional non-point pollutant treatment method has a problem in terms of cost and efficiency by mainly collecting and treating pollutants at the end of the water pipe.

In the following description of the present invention with reference to the accompanying drawings, the same components are denoted by the same reference numerals regardless of the reference numerals, and redundant explanations thereof will be omitted. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 and 2, a nonpoint pollution abatement facility having a walkway vegetation channel according to a preferred embodiment of the present invention will be described in detail.

1 is a schematic view illustrating a preferred embodiment of a non-point pollution abatement facility having a walkway vegetation channel according to the present invention.

As shown in FIG. 1, the non-point pollution abatement facility of the present invention includes a vegetation unit 100 in which a plurality of plants are spaced apart from each other by a predetermined distance on one side of a sidewalk BL contacting the roadway CL and vegetation is planted on the upper surface thereof. A collecting duct (200) connecting the plurality of vegetation units (100) to each other; And a collecting chamber 300 installed in an area where the collecting conduit 200 contacts the intersection.

The vegetation unit (100) includes a vegetation tank (110) in which a vegetation space is formed to receive a vegetated vegetation layer. The vegetation tank (110) is formed in a substantially rectangular shape and its upper surface is opened, As shown in FIG.

That is, the upper end of the vegetation tank 110 is lower than or equal to the road surface of the sidewalk BL, so that the rainwater runoff along the sidewalk BL and the road CL can reach the upper end of the vegetation tank 110, 100 to flow into the planting space.

FIG. 2 is a cross-sectional view taken along line A-A 'of a nonpoint pollution abatement facility having a walkway vegetation channel according to the present invention. Referring to FIG.

2, a space for containing the planting space and the filter media is formed in the vegetation tank 110. In a portion of the vegetation tank 110 adjacent to the road CL, A partition wall 111 for separating the interior of the partition wall 111 is formed. Therefore, the inside of the vegetation tank 110 can be divided into the filtration part 120 and the swollen part 130 by the partition 111.

The filtering unit 120 includes a plurality of filtering layers 121 for filtering out the rainwater and a planting layer 122 is provided on the upper surface of the filtering layer 121. Therefore, the rainwater flowing through the planting layer 122 can be filtered through the filter medium layer 121.

On the other hand, a water collecting conduit 200 for collecting and discharging the rainwater through the filter material layer 121 is inserted into the lower portion of the filter material layer 121. The water collecting conduit 200 is constructed to be the same as a pore tube and can collect rainwater that has passed through the filter medium layer 121 and penetrate the inside of the vegetation tank 110 to be continuously connected So that the stormwater can be continuously transported.

The filtration part 120 and the ridge 130 are separated by a partition wall 111. The height of the partition wall 111 may be relatively low as compared with the outer wall of the vegetation tank 110. [ Therefore, when a large amount of rainfall runoff flows into the filtration unit 120, the barrier ribs 111 are accumulated in the ridge 130 and then drained to the drainage pipe 104, It is possible to prevent flooding around.

The vegetation unit 100 includes a connection pipe 103 connected to the vegetation tank 110, a drain pipe 104 connected to the connection pipe 103, and a drain pipe 104 connected to the drain pipe 104 And a drainage trench 10. The drainage trench 10 is for collecting the stormwater flowing in the driveway, and the stormwater collected in the drainage trench 10 is drained through the drainage pipe 104.

Therefore, the storm stored in the ridge 130 in the vegetation tank 110 can flow into the drain pipe 104 through the connection pipe 103 and be drained to the outside. However, a reverse plate (not shown) may be installed in the connection pipe 103 so that the rainwater in the drain pipe 104 does not flow back through the connection pipe 103, or the connection pipe 103 may be inclined downward in the direction of the drain pipe 104 As shown in Fig.

The vegetation unit 100 configured as described above is collected through the stormwater collecting duct 200 passing through the filtering unit 120 of the vegetation tank 110 and continuously collected by the adjacent other vegetation unit 100 To be delivered. The rainfall amount increases and the storm surges flowing through the filtration unit 120 of the vegetation tank 110 can be introduced into the side sidewalls 130 and then drained to the drain pipe 104 through the connection pipe 103 .

Next, a second embodiment of the non-point pollution abatement facility having a car park vegetation channel according to the present invention will be described with reference to Figs. 3 to 5. Fig.

FIG. 3 is a perspective view of a second embodiment of a non-point pollution abatement facility having a vegetation canal for road assistance according to the present invention, FIG. 4 is a layout diagram of FIG. 3, and FIG. 5 is a sectional view taken along line B-B 'of FIG.

As shown in Figs. 3 to 5, when there is not enough space in the sidewalk BL unlike the case where there is a sufficient space for installing the vegetation unit 100 on the sidewalk BL as in the first embodiment of the present invention , The vegetation unit 400 is installed in a part of the roadway CL and the roadway CL is changed to the Cicane form to correspond to the second embodiment for not only processing the roadway but also reducing the roadway speed.

The second embodiment of the non-point pollution abatement facility having the car-washable vegetation channel according to the present invention comprises a vegetation unit 400 installed at alternate intervals in a drainage zone formed on both sides of the roadway CL; And a drainage passage 500 formed between the vegetation unit 400 and the sidewalk block 30.

The vegetation unit 400 is installed at both ends of the road CL and includes a vegetation tank 410 in which a vegetation vegetation layer is formed as in the first embodiment and an upper surface of the vegetation tank 410 is opened And the rainwater flowing in from the roadway CL is collected.

The side wall 411 of the vegetation tank 410 is formed higher than the roadway CL so as to form a boundary between the roadway CL and the vegetation tank 410. [ A plurality of inlet ports 413 are formed at the front end, the middle end, and the rear end of the side wall 411 of the vegetation tank 410 as shown in FIG. Therefore, as is well known, the roadway CL is formed to be slightly inclined in the direction of the sidewalk BL, so that the rain that flows down from the roadway CL moves along the side wall 411 of the vegetation tank 410, 413 to the inside of the vegetation tank 410.

The plane of the vegetation tank 410 may be formed in a streamlined shape as shown in FIG. 4 so that the inflow of rainwater can be smooth and the circulation line CL can be formed.

5, the sidewall side wall 412 of the vegetation tank 410 is formed so that the storm surges flow to the drainage flow path 500 formed at the side when the amount of rainfall increases. It is preferable that the sidewall side wall 412 of the vegetation tank 410 is formed to be lower than the sidewall sidewall 411 to form a step h.

Accordingly, even if a large amount of rainwater collects into the vegetation tank 410 due to an increase in the amount of rainfall, the rainwater does not flow to the drive side wall 411 but flows over the side wall 412 and drains smoothly along the side surface of the walkway BL .

The inside of the vegetation tank 410 may be formed with a filter material layer 414 and a plant material layer 415 as in the first embodiment and a water collecting pipe 420 in the form of a pipe is provided inside the filter material layer 414 . It is needless to say that the collecting ducts 420 may be connected to the collecting tubs 410 connected to each other at predetermined intervals.

When the amount of rainfall is small, the rainwater flowing along the roadway CL flows into the vegetation tank 410 through the inlet port 413, When the amount of rainfall is large, the rainwater flowing into the vegetation tank 410 flows through the sidewalk side wall 412 to flow into the drainage flow path 500 It is possible to prevent the vehicle from overflowing with the roadway CL.

The vegetation waterway of the present invention having the above-described structure has an effect of reducing the speed of the vehicle by forming a sycain curve that makes an S-shaped curve on the roadway.

6, the collecting duct 300 is connected to the area where the collecting duct 200 is in contact with the intersection 20, and the collecting water collected through the plurality of the vegetation units 100 ). ≪ / RTI > The collector 300 may be embedded in a lower portion of the ground 21 such as a signal waiting space of the intersection 20. [

The stormwater collected in the collection tank 300 can be utilized as domestic water, agricultural water, industrial water, or the like.

Fig. 7 shows a state in which the collecting filter 300 is installed at the inclined intersection 20. As shown in FIG. 7, the collecting unit 300 is installed in an area lower than the surrounding area, and the uphill and downhill lengths are formed on the basis of the collecting unit 300 so that the vegetation unit 100 is installed And may be configured to be connected by a collecting conduit (200).

Therefore, since the rainwater can be collected intensively by the vegetation unit 100 and the water collecting duct 200, the rainwater can be collectively concentrated by the water collecting 300 having a relatively low ground, Can be prevented.

The embodiments and the accompanying drawings described in the present specification are merely illustrative of some of the technical ideas included in the present invention. Therefore, it is to be understood that the embodiments disclosed herein are not for purposes of limiting the technical idea of the present invention, but rather are not intended to limit the scope of the technical idea of the present invention. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
