Description

[0001] The present invention relates to a non-point pollution water treatment system having a vegetation structure,

The present invention relates to a non-point source water purification system having a vegetation structure, and more particularly, to a non-point source water treatment system having a vegetation structure, We have created a beautiful aesthetic environment through the aquatic vegetation in the part and an environmentally friendly ecological environment in the city. Especially, the vegetation structure which enables the recycling and use of water by continuously infusing purified water filtered and filtered from the nonpoint pollutant into the surface layer And more particularly, to a non-point source water purification system having the same.

A drainage system including a collecting water pipe is installed at the edge of the road formed inside the boundary block to prevent the rainwater from accumulating at the time of rainfall, The rainwater is drained in real time through the house water pipe to prevent the flooding of roads and roads.

The drainage system prevents a large amount of dirt and trash from being introduced into the catching hole, smoothly discharges the stormwater, A grating is provided to enable a vehicle or a person to pass safely.

On the other hand, non-point pollution sources are pollution sources that run out along with runoff on the surface when rain is mainly applied. They are fertilizers, pesticides, soil sprinkling plants, housing spills, traffic pollutants, dust and garbage in urban areas, Residues, and air pollutants falling on the surface of the earth, and the excretion of all pollutants is actually the main source of nonpoint pollution.

 In particular, since there is no water purification function for a non-point pollution source including a large amount of non-point pollutants such as oil or grease or tire dust on the road in the early stage, there are many problems such as environmental destruction due to water pollution.

However, since the conventional drainage system merely performs the function of discharging the nonpoint source in real time, the nonpoint source containing the nonpoint source is discharged to the river, causing secondary environmental pollution caused by the nonpoint source, And it is pointed out that the water content of the ground is lowered, resulting in depletion of surface groundwater and desertification of the city.

To solve this problem, Korean Utility Model Registration No. 20-0459753 discloses that a pollutant is precipitated and separated by a purifier composed of a settling tank, an oil adsorption tank and a filter filtration tank, There has been proposed a non-point pollution source reduction apparatus capable of preventing water from accumulating in the sedimentation tank, oil adsorption tank and filter filtration tank, thereby preventing freezing in the winter season.

The non-point pollution source abatement devices sequentially filter the non-point pollutants introduced from the road through the filter body and discharge the pollutants to the ground or the outside, so that the original function of filtering and discharging non- have.

However, the non-point pollution source reduction apparatuses are configured to remove non-point pollutants by filtering them through the filter body, so that the filter body must be periodically cleaned or replaced, and odors may be generated when the filter body is contaminated.

As shown in FIGS. 2 to 6, the non-point source water treatment system 1 includes a guide block 100 disposed at a boundary between a road part and a delivery part, 11 ', 11', 11 ', 11 ", 11", 11 ", 11", 11 ", 11", 11 " , 11 ", 11 "') are formed; A grating portion 20 disposed on the upper portion of the buried main body portion 10 exposed to the guiding surface; A permeable filtration layer 30 formed at a lower portion of the buried main body portion 10 buried in the delivery portion and permeating the non-point contamination source introduced into the buried main body 10 to be filtered; And a vegetation tray unit 40 disposed on the permeable filtration layer 30 to form a planting space for aquatic plants.

Here, the embedding main body 10 is formed of a plastic molded product or a plastic injection molded product formed by injection molding of waste plastics. The grating portion disposed above the embedding main body and the embedding main body may have a desired shape such as a quadrangle, Can be produced.

A plurality of permeable holes 12 are formed in the lower side wall of the buried main body portion 10 so that the purified water filtered by the aquatic plant and permeable filtration layer portion 30 is discharged to the open buried main body portion 10 But also through the permeable holes 12 formed in the side walls to permeate the ground.

The permeable filtration layer portion 30 includes a gravel layer 31 stacked at the bottom and a masato layer 32 stacked on the gravel layer 32. The permeable filtration layer portion 30 includes a vegetation tray A function of supporting the roots of the aquatic plants cultivated in the unit 40 and a filtration function of permeating non-point pollutants contained in the non-point pollution source to permeate the ground through a double layer.

In addition, the vegetation tray 40 formed by layering on the permeable filtration layer 30 supports the roots of the aquatic plants having flexible stems and leaves such as reeds, prairies, and poplars.

At this time, the aquatic plants cultivated in the vegetation tray unit 40 penetrate roots and stably support the permeable filtration layer 30 formed at the lower part, and the stem and leaves of the aquatic plants are guided by the grating unit 20 So as not to inconvenience the passage of a pedestrian who is walking on the delivery portion while receiving sufficient sunlight required for growth.

5 and 6, the leaves of the aquatic plants grown in the embedding body 10 are exposed at a predetermined height to the upper portion of the guide through the grating portion 20, And has a sophisticated urban beauty through its leaves.

The nonpoint source of pollutants flowing through the connecting pipeline 110 of the boundary block 100 into the landfill body 10 along the road surface and the open top of the landfill body 10 along the landing surface Non-point pollution sources introduced into the landfill body 10 are removed by purification and filtration by an aquatic plant and a permeable filtration layer 30 growing in the vegetation tray 40, The purified water from which the material has been removed is slowly infiltrated into the ground through the lower openings of the buried main body portion 10 and the permeable holes 12 formed in the side portions to replenish the surface groundwater.

In the present embodiment, a plurality of inflow conduits 11, 11 ', 11' 'and 11' 'having thin shielding walls 11a are formed on one side of the upper portion of the embedding main body 10 as shown in FIGS. So that the constructor removes only the shielding wall 11a formed in the inflow conduit that is aligned with the left side and the right side of the connecting pipe 110 formed in the boundary block 100 so that the shielding wall 11a is removed So that the connecting pipe 110 and the buried main body 10 communicate with each other through the inlet pipes 11, 11 ', 11 "and 11' ''.

The constructor has a flexible pipe 15 installed in the connection pipe 110 of the boundary block 100 and the inlet pipe 11 'of the buried main body 10 as shown in FIG. 2, The nonpoint source of contamination introduced into the buried main body 10 through the connection pipe 110 of the block 100 is introduced into the buried main body 10 through the inflow pipe 11 '

Therefore, the buried main body portion 10, which is embedded in the lead portion formed inside the boundary block 100, is arranged in a row in the middle of the plurality of formed inlet pipes 11, 11 ', 11' The construction pipe is connected to the connection pipe 110 of the boundary block 100 through one of the inlet pipes 11 ' The buried main body portion can be buried.

That is, in the present invention, there is no constraint on the construction by changing the installation position of the embedding main body portion in order to line up the connecting pipeline formed in the boundary block 100 constructed in the construction process and the inflow channel of the embedding main body portion.

5, a plurality of float floaters 50 floated by the nonpoint source of contamination introduced into the buried main body 10 to raise the level of the nonpoint source are raised to raise the filtration pressure of the nonpoint source .

The floating floater 50 includes a floater member 51 having a lower specific gravity than water as a nonpoint source and an elastic rope member 52 for elastically fixing the floater member 51 to the vegetation tray portion 40 The elastic rope member 52 is made of a stretchable material such as a spring or an elastic rope so that the float member 51 is held in a state of being suspended by the vegetation tray 40 in a resilient manner.

On the surface of the floater member 51, the sunlight incident into the buried main body portion through the upper part of the opened buried main body portion 10 is prevented from reaching the root, and the incident light is reflected, And a reflection layer 51a to be incident on the stem are formed.

Therefore, even when a small amount of nonpoint source is introduced into the embedment main body 10, the floater member 51 resiliently lifted by the elastic rope member 52 made of a stretchable material floats on the inflowed nonpoint source, A higher water level is formed than the nonpoint pollution source substantially introduced into the water tank 10, and as a result, the stable water supply of the hydroponic plant and the permeation pressure of the nonpoint pollution source are increased due to the increased nonwater pollution source.

As a result, stable water supply to the hydroponic plants growing in the landfill body 10 and filtration pressure of the nonpoint source are formed, so that stable growth of the hydroponic plants and filtration of the non-point source are possible. Further, When the residual amount of the pollution source is small, moistening of the permeable filtration layer 30 is promoted, and the minimum moisture necessary for the growth of aquatic plants is preserved.

In the present embodiment, a "U" shaped ventilation circulation pipe 60 in which both ends are exposed to the atmosphere and the ventilation circulation part 61 formed at the center part is embedded in the permeability filtration layer part 30 is provided in the embedding main part 10 ).

Therefore, the permeable filtration layer portion 30 circulates the air introduced through the ventilation circulation portion 61, thereby promoting the decomposition of the non-point pollution source, thereby suppressing the occurrence of corruption and stably supplying air to the roots of the vegetated aquatic plants .

On the other hand, the non-point source water purification system 1 according to the present invention is characterized in that the aquatic plants are planted in the vegetation tray section 40, and the organic matter contained in the non- So that the non-point pollutants are purified.

Therefore, the aquatic plants are required to remove the aquatic plants that have undergone growth according to the growing period, and then plant new aquatic plants in the vegetation tray. Thus, the vegetation tray unit 40 is periodically placed in the embedding body 10, The intermittent withdrawal process is required.

Since the root of the vegetated plant cultivated in the vegetation tray 40 is permeated and supported by the permeable filtration layer 30 formed in the lower part of the vegetation tray 40, It is very difficult and laborious to take out the battery 40 by lifting it from the embedding main body 10.

Particularly, this phenomenon becomes more severe in the process of extracting the roots of the vegetation plant from the permeable filtration layer portion 30 by initially elevating the vegetation tray portion 40.

6 to 7, in this embodiment, a vegetation tray 40 provided to be received in the embedding body 10 is provided with a vertical structure for easily initializing the vegetation tray 40 in the embedding body 10 So that the vegetation tray section 40 is initially elevated with a small force.

In this embodiment, at least one elevation guide 41 is formed in the vegetation tray section 40 and an elevation rail 13 for guiding the elevation guides 41 to the elevation structure is provided on the inner wall of the embedding body section 10 ).

A rotating screw shaft 14 having a screw portion 14a is disposed upright on the lifting rail 13 so that the lifting screw shaft 41 of the vegetation tray portion 40 is passed through a rotating screw shaft 14, So that the vertical height of the vegetation tray 40 can be adjusted by rotating the rotary screw 14 in the forward and reverse directions.

At this time, a blowing portion 14b is formed at the upper end of the rotating screw shaft 14 so that the rotating shaft of the power tool T such as impact is coupled to the rotating screw shaft 14 through the blowing portion 14b, The rotary screw shaft 14 is rotated in the forward direction or the reverse direction by the provided rotational force to adjust the vertical phase of the vegetation tray unit 40. [

Therefore, when the exchangeable plant material of the aquatic plant is required, the operator binds the power tool T to the rotating screw shaft 14 to rotate the rotating screw shaft 14 in the forward direction, .

The roots of the aquatic plants supported by the permeable filtration layer 30 are pulled out by the initial elevation of the vegetation tray section 40 and then the manager elevates the vegetation tray section to the embedment section 10 to exchange the aquatic plants .

Thus, the present invention can prevent the vegetation tray from being lifted up through a heavy equipment such as a crane, and the operator can rotate the rotating screw shaft 14 in a forward direction through an electric tool or the like, It is possible.

The administrator can adjust the height of the vegetation tray 40 according to the growth condition of the aquatic plant using the elevation structure to adjust the height of the aquatic plant exposed at the upper part of the embedding body 10, It is possible to control the growth height of aquatic plants in consideration of growth conditions.
