The present invention relates to a rainwater receiver for filtering and draining pollutants flowing through the road surface during rainfall, and more particularly, the pollutants and wastes contained in the road surface drainage while maintaining the existing rainwater discharge function. The present invention relates to a multifunctional storm receiver that can reliably filter oily contaminants and prevent odors in the confluence area.

Generally, on the road surface, environmental pollutants such as particulates contained in exhaust gases emitted by automobiles, particularly diesel engine cars, dust from tire wear, and asphalt wear, etc. Is likely to accumulate with pollutants floating in the atmosphere.

In this way, the pollutants deposited on the road are transported to the road drainage due to rainfall, flowed into the sewer, and then discharged to the sewer. When the sewage system is a confluence type, the pollutant flows into the sewage treatment plant to be treated as sewage, but when it contains heavy metal or the like, it requires special treatment means such as high temperature heating treatment or solidification of the heavy metal into cement. There was a problem that is a big burden for sewage treatment.

If sewage is a classification, the pollutants will flow into the stream without being treated as sewage, and contaminants that have flowed into the river will cause eutrophication or act as environmental hormones, adversely affecting the ecosystem. The problem causing is being pointed out.

In order to overcome the above problems, conventionally, a number of excellent receiving of synthetic resin material has been proposed. These storm receivers include a settlement area; The basic structure consists of a filtration device and a road drainage storage space. These storm receivers store the road drainage during rainfall, transfer it to the filtration apparatus side, remove the pollutants contained in the road drainage, and discharge only the treated water to the sewer side.

However, the conventional storm receivers are made of synthetic resin materials of plastics in order to reduce manufacturing costs, but the transverse earth pressure acts on the storm receivers due to the traffic of vehicles, so that deformations frequently occur, resulting in high maintenance costs. There is a problem. In addition, the conventional rainwater receiver has a bypass outlet so that it can be bypassed in the case of a lot of rainwater or in case of emergency, in this case, the bypass outlet must be formed on the top of the filtration tank, so a considerable height is required. Accordingly, there is a problem that the entire structure of the rainwater receiver is deep.

On the other hand, when storm drains are installed in the joining area, odors flow back through the storm drains from the sewage main building. To prevent this, conventionally, the odor prevention system is separately installed on the grating lid, but this not only acts as a factor in greatly increasing the cost of the product, but also in the case of an error in the operation of the hinge part due to a long time, excellent exclusion There is a problem that there is a risk of losing its original function.

Therefore, the present invention has been proposed to solve the above problems, and has excellent road surface drainage ability while maintaining the basic function of removing the pollutants carried by the road drainage well while maintaining the basic function as it is, the smooth excellent It is possible to eliminate, to make the multi-stage connection possible, to deepen the installation depth while resisting transverse pressure, and to provide a multifunctional storm receiver that can reliably filter contaminants and floating substances included in road drainage. There is a purpose.

Another object of the present invention is to provide a multifunctional storm receiver having fixed bed particles and a fluidized bed medium to prevent turbulence and to reduce maintenance frequency due to an increase in the solid penetration depth.

In order to achieve the above object, the present invention is installed at a predetermined position of the road surface drainage path, the outer housing provided with a drainage pipe at a lower predetermined position; Is installed inside the outer housing, the space for storing the road surface drainage is formed, the first space for the storage space is introduced into the rainwater, the second space for filtration of the road drainage, and the A treatment tank that divides the two spaces into a third space discharged to the sewer pipe; A grating cover installed at an upper opening of the outer case and having an inlet for introducing rainwater; And it is provided in the second space of the treatment tank provides a multifunctional storm receiving means for filtering and adsorption to remove the contaminants contained in the road surface drainage rising from the bottom of the treatment tank to the upper side.

Hereinafter, with reference to the accompanying Figures 1 to 7 will be described a preferred embodiment of the present invention.

The multifunctional storm receiver according to the present invention can efficiently treat various pollutants contained in the road drainage during the initial rainfall stage, while maintaining the basic function of smoothly increasing road drainage during rainfall, It is implemented to prevent the occurrence of odor.

The present invention can be applied to the case of removing contaminants contained in the road drainage at approximately 20m intervals in the sideways or sidewalks installed next to the road curb, for example, between the driveway and the sidewalk.

1 and 2, the detailed configuration of the present invention, as shown in the drawing, is installed at a predetermined position of the road surface drainage path, the outer housing 2 provided with a drain hole (2a) on the lower side; A drainage device (4) installed in the drainage hole of the outer enclosure (2) for discharging the filtered water to an external sewage pipe or waterway embedded in an extension direction of the roadway; The storage space is divided into a plurality of spaces to be installed inside the outer housing 2 to form a space for storage of road drainage, and to filter various foreign matters contained in the road drainage in sequential steps. A processing tank 6; A grating lid 8 installed at an upper opening of the outer case 2 to introduce rainwater; And a filtration device 9 provided in one space of the treatment tank 6 to filter, adsorb, and remove contaminants contained in the road surface drainage rising upward from the lower portion of the treatment tank 6.

The outer housing (2) is a multi-stage coupling structure to be used when a lot of transverse earth pressure is applied to the traffic of the vehicle, or when the depth of the rain receiver needs to be deepened. That is, the outer case 2, as shown in Figures 2 and 4, and the rectangular body 12 through which the inside; A multistage frame (14) fitted inside the body (12); And a flange 16 fitted to the multi-stage frame 14 and coupled to the body 12.

Similarly, fixing holes 16b of the same size are formed in the flange 16 at positions corresponding to the fixing holes 12b and 14b. In addition, the body 12 and the multi-stage frame 14 is provided with a plurality of T-section dovetail joint member (18) in the longitudinal direction to enable the slide coupling on their inner and outer surfaces, the flange 16, a guide groove 16a for fitting the T-shaped dovetail of the multistage frame 14 on the inner circumferential surface is formed.

Therefore, when it is necessary to further deepen the depth of the rain receiver, the T-shaped dovetail of the multistage frame 14 is inserted into the guide groove 16b of the flange 16, and the supporting jaw of the body 12 is provided. After mounting the flange 16 to which the multi-stage frame 14 of 12a is coupled, bolts are fixed to the fixing holes 12b, 14b, and 16b. Thus, the multi-stage frame 14 can be assembled in two or more stages. In the assembly process, the flange 16 is assembled in the middle of the multi-stage frame 14 to perform a function as a reinforcing member to prevent the multi-stage frame 14 from being twisted by lateral earth pressure.

As shown in FIGS. 2 and 3, the drainage device 4 has a locking jaw portion at one end thereof so as to cover the drainage hole 2a of the outer enclosure 2, and an outlet socket 22 having a male screw formed on an outer circumferential surface thereof. )and; A socket nut 24 for fastening the outlet socket 22 to the male screw of the outlet socket 22 so as to be firmly fixed to the drain hole 2a; It is interposed between the outlet socket 22 and the nut 24 is composed of a wedge ring 26 for adjusting the installation angle of the outlet socket.

The present embodiment may further include a odor counter flow prevention device (10) installed in the drainage device (4) to prevent the odor flow back to the rainwater receiving side from the sewer main pipe.

7A and 7B, the odor backflow preventing device 10 is fitted to the outlet socket and has a plastic fixing frame 32 of a comb-tooth structure that is circumferentially outwardly opened; It is fitted to the comb teeth of the fixed frame, it is composed of a tube-shaped deodorizing film 34 made of a material that is low in hardness, such as rubber, synthetic fabrics and the like.

Therefore, when the road drainage is small or the amount is small, the deodorizing membrane 34 is settled by its own weight to shield the outlet 2b (see FIG. 7A), and when the road drainage increases to increase the flow rate of the discharged water, The deodorizing membrane 34 is expanded to discharge the road surface drainage (see FIG. 7B).

As shown in Fig. 2, the treatment tank 6 has a support plate 42 having a size corresponding to the inner area of the outer housing 2 and forming a bottom surface thereof; Acupuncture receiving bowl 44 provided with a support plate 46 that is woven to form a space of "A" shape on one side of the upper surface of the support plate 42 and extends from one side of the "A" space to the outside. and; It is erected in the form of a grid bent, one end crosses a part of the upper surface of the needle receiving barrel 44, the other end is connected to the edge of the support plate 46 to provide an inflow path of the road surface drainage at the beginning of the rain, A flow path partition plate 48 formed at an upper side thereof to provide an inflow path at the beginning of rainfall; A screen 50 for tilting the inner surface of the flow path partition plate 48 to filter coarse contaminants included in the road drainage water flowing into the interior of the flow path partition plate 48; A bypass gate 52 installed on the side surface of the flow path partition plate 48 and automatically opened and closed according to an increase in the water level; A filtration tank 54 having a space portion divided by the flow path partition plate 48, for filtering road surface drainage rising from the saliva receiving tank 44; And a partition plate 56 having a lower height than the flow path partition plate 48 and extending from the side thereof to divide the space into the filtration tank 54 and the drain tank.

In the present embodiment, the sedimentation basin 44 is made of a fine screen of 2 mm or less, and the drainage hole 2a of the outer case 2 is formed at the bottom, so that water is accumulated inside the rain catcher after the rainfall is over. It is designed to be discharged smoothly.

The treatment tank 6 includes a first space 61 into which initial rainwater flows through the flow path partition plate 48 and the partition plate 56; It is divided into a second space 62 for filtering road surface drainage, and a third space 63 that overflows the second space and discharges the sewage pipe.

Here, the bypass gate 52 is a hinge 53 is installed in the middle of the window 48a of the flow path partition plate 48 in the axial direction (horizontal direction) as shown in Figs. 5a and 5b. It is supported, and the center of gravity is located below. Therefore, in the state where the storm receiver secures the water level at the normal operation, the bypass gate 52 shields the window 48a of the flow path partition plate 48 (see FIG. 5A), and when the water level rises, the pressure is increased. As a result, the bypass gate 52 is opened so that the bypass gate 52 is immediately discharged without passing through the filtration tank 54 by the rising water level (see FIG. 5B).

The filtration tank 54 is positioned lower than the flow passage partition plate 48 by a predetermined interval, thereby forming a predetermined interval between the grating lid 8 and the amount of rainfall exceeding the processing capacity of the storm receiver. When it falls down, it flows directly into the 3rd space 63, and is discharged | emitted to the drain hole 2a.

As shown in Figs. 6A and 6B, the filtration apparatus 9 includes a fixed particle layer 66 stacked at a predetermined height provided at the bottom of the filtration tank 54; Stacked at a predetermined height on top of the fixed particle layer 66 and includes a fluid particle layer 68 that flows up and down in accordance with the increase or decrease of the water level of the road surface drainage. The fixed particle layer 66 is composed of particles having a high specific gravity, for example, in the present embodiment is made of steel beads. The fluid particle layer is a filter medium, and the filter medium may be made of fine pieces of a material having a high ability to adsorb a lipophilic material and the like and easy to disturb the washing and light weight, for example, a foamed polypropylene material. Therefore, by placing particles having a high specific gravity at the bottom of the filtration tank 54, the turbulence generated as the road drainage flows through the flow path partition plate 48 minimizes the influence of the turbulence on the filtration layer to induce a plug flow to increase the filtration efficiency. Raise.

In particular, when contaminants are concentrated on the inlet (bottom) surface of the filter medium, the filter medium is easily occluded, thereby increasing the frequency of maintenance such as replacement of the filter medium. After sinking (shown in Fig. 6a), when the rainwater flows in the rainy season, the filter media floats when the water fills up, and contaminants can penetrate deeply into the filter layer, increasing the contaminant trapping layer. It is possible to reduce the maintenance frequency due to occlusion (shown in FIG. 6B).

Referring to the working state of the present invention configured as described above are as follows.

First, the outer housing 2 is assembled in consideration of the transverse earth pressure according to the traffic volume of the vehicle, taking into account the depth of the storm receiver. At this time, the outer housing 2 seats the multi-stage frame 14 on the upper stepped portion 12a of the body 12, is coupled using the flange 16, and then covered with the treatment tank 6 to be assembled. To complete. In addition, a drainage hole 2a is formed on the third space 63 side of the outer housing 2 by post processing, and the outlet socket 22 is fitted from the inside to the outside. Then, the socket nut 24 is fastened and fixed, and the angle of the outlet socket 22 is adjusted using the wedge ring 26. In addition, the outlet socket 22 is provided with a odor reflux device 10 consisting of a fixing frame 32 and a deodorizing membrane 34 to prevent the bad smell from the sewer pipe to flow back to the excellent receiving side in normal times.

The various pollutants deposited on the road surface are transported along with the contaminants by the road drainage through the initial rainfall to reach the side of the road, and the road drainage containing the contaminants and the contaminants is passed through the grating lid (8). It flows into the 1st space 61 divided by). The coarse miscellaneous material included in the road drainage is filtered by the screen 50 inclined to the flow path partition plate 48.

The road drainage which flows into the first space 61 and reaches the sedimentation container 44 is directly moved to the filtration tank 54 so that the water level gradually increases. At this time, the stopper flow is induced by the fixed particle layer 68 installed at the lower end of the filtration tank 54, thereby minimizing turbulence, thereby increasing the filtration efficiency.

When the water level rises in the filtration tank 54 as the road drainage flows in during the rainy season, the floating particle layer 66 that floats is repeated. Accordingly, various contaminants included in the road drainage are filtered by the filter medium, and the treated water passing through the filtration tank 54 flows into the third space 63 and is discharged through the drain hole 2a. When the treated water is discharged through the drainage hole 2a, the deodorization membrane 34 installed in the outlet socket 22 is opened by the water flow and smoothly discharged. In the filtration process, the contaminants penetrate deeply into the media and increase the fouling collection layer in the media, thereby reducing the frequency of maintenance due to the blockage of the media.

When there is a lot of rainfall per hour, the first space 61 and the filter tank 54 may be filled with inflow water during the rainfall, so that the road drainage may not be able to enter. In this case, the excess water grating lid 8 Inflow into the upper side of the filtration tank 54, but is directly introduced into the third space (63) with the treated water is discharged. Since the road drainage discharged directly in this way does not pass through the filtration tank 54, the pollutant removal process is not performed. However, the removal of contaminants deposited on the road surface by storm drains is almost completed in the initial rainfall stage. Therefore, the amount of contaminants in the road surface drainage due to the subsequent rainfall is small, and it can be said that there is little problem even if the excess water is discharged immediately without passing through the filtration tank 54.

On the other hand, during the rainy season, if the process by filtration as the rainwater flows in normally, the water level by filtration can be secured by forming a water level slightly above the filtrate as shown in Figure 5a, the water level is higher than that When rising, as shown in FIG. 5B, the bypass gate 52 is opened so that excessive rainwater is discharged directly to the third space 63, thereby smoothly draining the rainwater. In addition, since the bypass gate 52 shares some overlapping height with the filtrate, it is possible to secure a sufficient bypass cross section required for filtration while reducing the height of the device.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
