Description

Eco-friendly water filtration and treatment system

The present invention relates to an eco-friendly filtration water treatment system among water treatment technologies. More specifically, it is installed between roadways and sidewalks to plant herbaceous plants, small shrubs, and arboreal trees used as street trees, thereby saving urban aesthetics and rainfall. The effluent is filtered to remove pollutants, and the filtered water from which the pollutants have been removed is allowed to infiltrate into the ground to form groundwater or to supplement existing groundwater, so that rainfall effluent can be treated eco-friendlyly. It relates to an eco-friendly filtration water treatment system that prevents the soil from being lost to the road surface and sidewalks, so that the vegetation that was planted does not fall over, or the roots are exposed or pulled out.

In general, pollutants that occur in urban areas are classified into point pollution sources and nonpoint pollution sources.

Point pollutants are pollutants that have a specific discharge path, such as domestic sewage and factory wastewater, where the pollutant discharge source can be expressed as a single point, and its movement path is clear and relatively easy to treat.

Non-point source is an emission source that discharges unspecified pollutants from unspecified places such as cities, roads, farmland, mountains, and construction sites.

Unlike point pollutants that continuously occur at specific points, such as domestic sewage or factory wastewater, non-point pollutants are scattered pollutants. It is difficult to determine the exact route of outflow, and the amount of generation, discharge, precipitation, etc. are largely dependent on weather conditions. It is characterized by being discharged to a large area as it is diluted and diffused.

In addition, types of non-point pollutants include soil, nutrients (floating substances, nitrogen, phosphorus), bacteria and viruses, oil and grease, heavy metals, organic substances, pesticides, and impurities.

The importance of non-point pollutant sources as pollutants was not recognized because they are intensively discharged only during rainfall and the pollutants are scattered over a wide area. However, the first flush runoff from which non-point pollutants from the surface of the surface flow out during the early rainfall is high in runoff concentrations of non-point pollutants, and especially in urban areas, the possibility of containing toxic substances such as heavy metals is high, so appropriate control measures are required. Has become.

The outflow of non-point pollutants due to rainfall is very irregular, contains many kinds of non-degradable non-point pollutants, has large fluctuations in the amount of generation and load, and has a high concentration at the beginning of rainfall.

Therefore, contaminants such as soil, nutrients, and heavy metals of high concentration, which are discharged from non-point sources along with rainfall, are relatively difficult to manage and treat. However, if they are introduced directly into the river without special treatment, they seriously contaminate the water quality. There is a problem that the aquatic ecosystem is disturbed due to mass mortality or destruction of benthic organisms.

Conventionally, in order to reduce such non-point pollutants, various kinds of eco-friendly non-point pollutant reduction facilities have been developed.

As a prior art, Korean Patent Registration No. 10-0910661 (Announcement on Aug. 05, 2009) "Ecological Expansion Tree Box Filter System for Reduction of Non-point Pollution on Roads" (hereinafter referred to as'Prior Technology 1') is a street tree space around the road. It is to reduce road non-point pollution by using, including a tree box buried at the side of the road so that the upper part is higher than the road surface while having a vegetation space in which a street tree is planted or a flower bed is formed, and the road is in contact with the road side. An inlet hole is formed in the side wall of the tree box exposed above the surface so that the running water of the road surface can pass, and the inside of the tree box is filtered to filter non-point contamination contained in the running water introduced into the tree box through the through hole. A floor and a perforated pipe for discharging the filtered running water are installed, and an eco-friendly green space that forms a huge green belt in the city can be created by connecting adjacent tree boxes of street trees to use as a vegetation space to reduce non-point pollution. Since the non-point pollution generated on the road surface is reduced by using the previously installed street tree space, it is economical because it does not require a separate space, and the upper part is a normal street tree space, so it is disclosed a technology that provides an eco-friendly non-point pollution reduction technology.

In addition, as a prior art, Korean Patent Registration No. 10-1294208 (announced on August 16, 2013) "Tree Filter Box" (hereinafter referred to as'prior art 2') has a perforation hole in the bottom plate, and an inlet and an outlet are provided. In order to plant vegetation, including a box block, a gravel layer stacked on the bottom plate, vegetation soil filled on the gravel layer, a surface filter material stacked on the vegetation soil, and a perforated pipe buried in the gravel layer and vegetation soil. As a result, water pollution is prevented and land use efficiency is improved by reducing non-point pollutants in surface water such as rainfall runoff by using a landscaping space in which vegetation is planted without installing a facility for reducing non-point pollutants in a separate space. In addition, a technology that can contribute to the expansion of groundwater by infiltrating the treated water into the basement is being disclosed.

In addition, as a prior art, the Republic of Korea Patent Registration No. 10-1343005 (announced on December 8, 2013) "Tree rainwater management device for filtering non-point pollutants" (hereinafter referred to as'priority technology 3') is an internal space in which trees are planted. The tree box is formed and has an open top and a plurality of water inlet holes are formed in the upper side of the side, and a water discharge hole is formed in the lower side of the tree box. A space part is formed, a transmission tank having a plurality of water permeable holes communicating with the water inlet hole formed on the side surface, and a second space part formed between the side surface of the transmission tank and disposed to surround the side surface of the transmission tank, and the water in the side surface. Including a storage tank in which a water inlet hole communicating with the through hole and opening toward the road surface is formed, and a protective plate mounted on the top of the storage tank so as to cover the top of the tree box, the transmission tank, and the storage tank, the sidewalk in contact with the road surface Since rainwater is introduced into the tree space to be installed, filtered, and then penetrated into the soil or stored in a separate storage tank, it is possible to create an underground environment in which water circulates in the groundwater layer and to increase the utilization rate of rainwater.

However, prior technologies are configured so that the rainfall runoff flowing along the road surface and sidewalks flows into the tree box in case of rainfall, regardless of the flow rate, so that there is more than the quantity that can pass through the colored soil inside the tree box during heavy rain. When a large amount of rainfall runoff flows in, the whole tree box is flooded, and vegetation soil is lost to the road and sidewalks, causing the planted vegetation to fall over, revealing or pulling roots, and losing the function as a tree box. have.

Hereinafter, the operation of the eco-friendly filtration water treatment system according to the present invention will be described.

Water passing holes (431, 631, 831, 531, 731, 931) of water passing plates (430, 630, 830, 530, 730, 930) are closed by opening and closing plates (440, 640, 840, 540, 740, 940) When the rainfall starts in the state that the first vegetation infiltration tank 100, the second vegetation infiltration tank 200, the filter infiltration tank 300, the first to third roadway side inflow tanks 400, 600, 800, and the first to In the third sidewalk side inflow tanks 500, 700, 900, the rainfall runoff from the sidewalk 10 and the rainfall runoff from the sidewalk 20 along with the rainfall falling thereon are introduced.

Precipitation water falls on the first vegetation soil pack 140 of the first vegetation infiltration tank 100 and flows into the second vegetation soil pack 240 of the second vegetation infiltration tank 200. It falls on the third gravel pack 320 and is introduced.

In addition, rainfall is generated through the steel grating (460, 660, 860, 560, 760, 960) through the first to third driveway side inflow tanks (400, 600, 800) and the first to third sidewalk side inflow tanks (500, 700). , 900) of the upper half (420, 620, 820, 520, 720, 920) is introduced into the inner space.

The rainfall runoff on the driveway side is through the inlet hole 31 of the boundary stone 30 and the first to third driveway inlet ports 421, 621, 821 of the first to third driveway inflow tanks 400, 600, 800. It is introduced into the inner space of the upper half-jo (420, 620, 820).

The rainfall runoff on the sidewalk is the upper half (520, 720, 920) through the steel grating (460, 660, 960) of the first to third sidewalk side inflow tanks (500, 700, 900) from the surface of the sidewalk block (40). Flows into the inner space of

At this time, the water passing holes (431, 631, 831, 531, 731, 931) of the water passing plates (430, 630, 830, 530, 730, 930) are on the opening and closing plates (440, 640, 840, 540, 740, 940). Because it is closed by the first to third roadway side inflow tanks (400, 600, 800) and the first to third sidewalk side inflow tanks (500, 700, 900), the upper half of the tank (420, 620, 820, 520, 720) , 920) does not flow into the lower half tank (410, 610, 810, 510, 710, 910), and the first vegetation soil pack 140 and the first of the first vegetation infiltration tank 100 It flows only into the second vegetation soil pack 240 of the vegetation infiltration tank 100 and the third gravel layer 320 of the filter infiltration tank 300, and does not flow into the lower half tanks (410, 610, 810, 510, 710, 910). This is not done (refer to solid lines in Figs. 6, 9, and 12).

The rainfall water and rainfall runoff flowing into the first and second vegetation infiltration tanks (100, 200) are the first and second sand packs (130, 230) and the first and second vegetation soil packs (140, 240). The filtered water from which pollutants are removed by filtering while passing through the second gravel pack (120, 220) penetrates into the ground through the infiltration holes (113, 213). 3 The filtered water from which the pollutants are removed while passing through the gravel pack 320 penetrates into the ground through the infiltration hole 313.

The filtered water that has penetrated into the ground forms or supplements groundwater. As described above, since the pollutants have been removed, contamination of the groundwater can be prevented.

On the other hand, the first to third roadway side inflow tanks 400, 600, 800 and the first to third sidewalk side inflow tanks 500, 700, 900 due to continuous rainfall or concentrated heavy rain. , 820, 520, 720, 920) when the water level in the buoyancy body (450, 650, 850, 550, 750, 950) is higher than the bottom of the buoyancy body (450, 650, 850, 550, 750, 950) acts on the buoyancy body (450, 650, 850, 550, 750, 950) The opening and closing plates 440, 640, 840, 540, 740, 940 are lifted by the buoyant force to open the closed water holes 431, 631, 831, 531, 731, 931 (Figs. 7, 8, 10, 11, 13 and 14, see dotted lines].

Accordingly, a part of rainfall and rainfall in the upper half tide (420, 620, 820, 520, 720, 920) is reduced through the upper half tide (420, 620, 820, 520, 720, 920) and the lower half tide (410, 610, 810). , 510, 710, 910), where it penetrates into the ground through penetration holes 411, 611, 811, 511, 711, 911.

In this case, part of the rainfall and rainfall in the upper half tank (420, 620, 820, 520, 720, 920) is the first vegetation soil pack 140 and the first vegetation infiltration tank 100 of the first vegetation infiltration tank 100. The first and second sand packs 130 and 230 and the first and second gravel packs 120 are introduced into the third gravel layer 320 of the second vegetation soil pack 240 and the filter permeation tank 300 of the 220) and the action of removing pollutants by the third gravel pack 320 and the action of penetrating the ground through the penetration holes 113, 213, and 313 are performed continuously.

Therefore, in the upper half tank (420, 620, 820, 520, 720, 920), the first vegetation soil pack 140 of the first vegetation infiltration tank 100 and the second vegetation soil pack 240 of the first vegetation infiltration tank 100 And the flow rate of rainfall water and rainfall runoff flowing into the third gravel layer 320 of the filtration permeation tank 300 is reduced to prevent inundation of the first vegetation infiltration tank 100 and the second vegetation infiltration tank 200 and the filtration infiltration tank 300 And, the vegetation soil in the first and second vegetation soil packs (140, 240) is lost to the road and sidewalks, causing the planted vegetation to fall over, revealing the roots, or being pulled out, thereby losing the function as a tree box. There will be no.

Thereafter, rainfall has subsided or ceased, and the upper half of the inflow tanks 400, 600, 800 on the first to third roadways and the inflow tanks 500, 700, 900 on the first to third sidewalks (420, 620, 820) , 520, 720, 920) when the water level in the buoyancy body (450, 650, 850, 550, 750, 950) is lower than the bottom of the buoyancy body (450, 650, 850, 550, 750, 950) The buoyancy decreases and the opening and closing plates 440, 640, 840, 540, 740, and 940 descend to close the water passing holes 431, 631, 831, 531, 731, and 931.

As described above, according to the eco-friendly filtration water treatment system of the present invention, it is possible to save the appearance of the city by planting herbaceous plants, small shrubs, and arboreal trees used as street trees by being installed between the roadway and the sidewalk, and filtering the rainfall runoff to remove pollutants. It is possible to form groundwater or supplement existing groundwater by allowing the filtered water from which pollutants have been removed to penetrate into the ground, thereby enabling environmentally friendly treatment of rainfall runoff.

In the above, the present invention has been described with reference to the drawings exemplified as preferred embodiments, but the present invention is not limited by the illustrated embodiments and drawings, It goes without saying that various modifications can be made by a technician.
