Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a compact type superior inlet having purifying non-point pollution,

The present invention relates to a compact type well having a function of purifying non-point pollution of an excellent flowing on a surrounding road surface.

Generally, on one side of the road, a rainwater which collects rainwater flowing on the surrounding road surface is buried. By discharging the stormwater that is collected by the stormwater to the sewer in connection with the sewer, the stormwater is not left on the road surface in the rainy weather, and safe operation is possible. Rain on the road surface contains various pollutants. For example, on the road surface, there may be fine particles of exhaust gas, dust caused by tire wear, dust caused by asphalt abrasion, fine pollutants such as soot or dust floating in the air, and other municipal waste. Or it may be a precipitate or an insoluble matter in the oil component.

These pollutants are called non-point pollutants. They are mainly pollutants that come out along with the surface runoff when it rains. They are fertilizers, pesticides, soil sprinkling plants, housing spills, traffic pollutants, dust and garbage in urban areas, And air pollutants on the surface of the earth. Non-point pollutants mostly remain on the surface of the ground, and then enter into rivers and groundwater together with stormwater, leading to water quality and soil pollution. In order to solve such a problem, one side of the road and the sidewalk is provided with an excellent receiver for purifying the non-point pollution of the storm and discharging it to the sewer.

There are many facilities such as gas pipes, power lines, communication lines, etc. in addition to the waterways and sewage pipes in the underground. Most of the prior art receivers disclosed in Korean Patent No. 10-1099768 provide a structure in which a plurality of layers are stacked horizontally or vertically in order to improve the purification performance of the excellent, A conventional water cannon has to be manufactured in a large size. Accordingly, in order to install a conventional superior receiver, it is necessary to secure a large space under the road without underground facilities, so that it is difficult to install the conventional receiver. In addition, there has been a problem in that replacement or cleaning of the filter media frequently occurs due to the deterioration of the filter medium.

The present invention is to provide a supersonic receiver which can be manufactured compactly while satisfactorily cleansing the inflows from the surrounding road surface and hardly deteriorates the purification performance due to clogging of the filter media due to dirt. The present invention is not limited to the above-described technical problems, and another technical problem may be derived from the following description.

A compact type well having a function of purifying non-point pollution of an excellent flowing on a surrounding road surface according to the present invention is formed into a rectangular pipe shape having an upper surface and a lower surface opened and embedded in a road surface underground. At least one grating installed on an open top surface of the housing so as to be inclined so as to be continuous with an inclination of the surrounding road surface, A purifying module located inside the housing and passing through the at least one grating to purify stormwater flowing into the housing; And a storage tank embedded in the lower side of the housing and discharging the purified water purified by the cleaning module to the ground.

The purifying module comprising: a lower box formed in a box shape in which at least one lower tube protrudes upwardly from an inner bottom surface, the lower box receiving rainfall falling through the at least one grating; And at least one upper tube communicating with at least one lower tube of the lower box is formed in a box shape protruding downward from a lower surface of the lower box, And an upper box for filtering and discharging the inflowing stormwater to the storage tank.

As the level of the rainwater in the housing increases, the rainwater in the housing passes through the filtration tube in the direction opposite to the gravity direction and flows into the space of the upper box above the filtration tube. As the water level of the rainwater in the housing is lowered, The floating matter of the surface of the fine particles in the filter medium is released from the porous bottom surface of the filter case and the surface of the filter medium.

As the level of the rainwater in the housing is lowered, a part of the rainwater in the space of the upper box above the filter box passes through the upper pipe of the upper box and the lower pipe of the lower box communicating with each other, The remaining portion of the rainwater in the space of the upper box above the filter box is discharged to the inner space of the lower box through the filter box and the upper tube and the lower box of the upper box communicated with each other in a state in which the storage tank is not fully charged, The water pressure of the stormwater in the lower pipe of the upper tank is lower than the water pressure of the stormwater in the lower pipe, The amount of the exhaled air may be large.

The purifying module is formed in the form of a perforated plate and covers the opening of the inner bottom surface of the upper box corresponding to the outlet of the filter box to block the outflow of the filter media packed in the filter box. And the purifying module further comprises an upper lid formed in the form of a non-porous flat plate to cover the open upper surface of the upper box so as to prevent the storm that has passed through the at least one grating from falling into the inside of the upper box, The upper cover is detached from the open upper surface of the upper box and moved to the outside of the purifier module. After the lower cover is separated from the opening of the inner bottom surface of the upper box and moved to the outside of the purifier module, The filter material filled in the inside can be exchanged or washed.

Wherein a bottom surface of the filter box is protruded downward so as to contact a bottom surface of the bottom box, the bottom surface of the filter box dividing the bottom surface of the filter box into a plurality of fan-shaped areas, A hole may be formed.

Wherein the purifier module is installed in a lower space at one end of the uppermost one of both ends of the at least one grating in an oblique direction so as to first receive and purify storms introduced from the surrounding road surface, And a grating region in which the storm is introduced due to an increase in flow rate and flow rate of stormwater introduced from the surrounding road surface is provided in the lower space of the other end of the lowest position of both ends in the oblique direction of the at least one grating, The auxiliary filter may filter the rainwater falling into the space below the other end of the at least one grating.

The storage tank is a primary storage tank buried in the lower side of the purifying module and discharging the purified water purified by the purifying module to the ground. The compact type well is buried in the lower side of the auxiliary filter, And may further include a secondary storage tank that discharges to the ground.

The primary storage vessel and the secondary storage vessel are embedded in the lower side of the housing such that the upper surface of the primary storage vessel and the upper side of the secondary storage vessel form a continuous plane at the same height, The periphery of the lower opening of the auxiliary filter is attached to the periphery of the upper surface opening of the secondary storage so that the purifying module is seated and coupled to the upper surface opening of the primary storage tank so that the auxiliary filter is protruded from the upper surface of the secondary storage tank The inner space of the lower box can form a depression on the bottom surface of the housing.

Wherein the upper surface of the storage tank is formed in a rectangular shape in which the lower box can be seated, and each of the four side surfaces and the lower surface is formed in a frame form; And an opening portion of a side surface and a bottom surface of the tank, and passes through the upper pipe of the upper box and the lower pipe of the lower box, which are in communication with each other, in order to filter out the rainwater flowing into the tank, Sheet.

The height of the upper end of the auxiliary filter is lower than the height of the inner bottom surface of the upper box and the height of the lower end of the compact type well is equal to the height of the upper surface of the purifier module, And a drain pipe embedded in a side wall of the drain pipe and connected to the sewage pipe.

At least one lower tube of a box shape in which at least one lower tube protrudes upward from the inner bottom surface and at least one lower tube which is communicated with at least one lower tube of the lower box, By using a structure in which a box-shaped upper box protruding downward from the lower surface of the upper pipe is used, filtration of the floors on the surface of the filter is performed by a filtration-pipe-porous bottom surface in which the storm is passed in the direction opposite to the direction of gravity, It is possible to satisfactorily purify the storm. As a result, a purification module that plays a role of purifying stormwater can be compactly manufactured, and a housing with such a purification module can be compactly manufactured, so that it can be freely installed in a road underground where many underground facilities exist.

Further, as the level of the rainwater in the housing increases, the rainwater in the housing passes through the filter case in the direction opposite to the gravity direction and flows into the space of the upper box above the filter case. As the water level of the rainwater in the housing is lowered, Since the float is separated from the porous bottom surface of the filtration tube and the surface of the filter medium, there is hardly any clogging of the filter medium due to the fine particles suspended in the solid matter such as leaves or paper pieces or the oil film. As a result, the deterioration of the purification performance due to the pore clogging of the filter media due to the excellent dirt is hardly caused.

Further, the water pressure of the rainwater in the upper and lower tubes of the upper box communicated with each other in a state in which the storage tank is not fully charged is lower than the water pressure of the rainwater in the filtration tube, The amount of stormwater discharged through the upper pipe of the upper box and the lower pipe of the lower box sequentially through the storage tank becomes much larger. In addition, since the stormwater in the storage tank is discharged to the ground, the storage tank is not fully charged, and therefore the amount of stormwater passing through the filter medium in the gravity direction is insignificant. As a result, the amount of storm water passing through the filter material is remarkably reduced, so that the wear of the filter material is slowed down, and the filtering performance of the filter material can be maintained for a long time as the performance of the filter material is established.

The upper lid is also detached from the open upper surface of the upper box by blocking the fall into the interior of the upper box by opening the upper surface of the upper box and covering the open upper surface of the upper box with the upper lid Can be moved to the outside of the purification module. After the upper cover is moved to the outside of the purifier module, the filter material filled in the filter box can be easily exchanged or washed with the lower cover separated from the opening of the inner bottom surface of the upper box and moved to the outside of the purifier module .

Since the spiral projections for dividing the lower surface of the filtration tube into a plurality of fan-shaped regions protrude downward on the lower surface of the filtration tube so as to come in contact with the inner bottom surface of the lower box, flexible dirt such as vinyl sheets It is impossible to cover the whole area. As a result, even if the flexible dirt flows into the lower box, the dirt can smoothly flow into the filter case through the other fan-shaped areas on the lower surface to which the flexible dirt does not flow.

In addition, the purifying module is installed in a lower space at one end of the uppermost one of both ends in the slanting direction of the grating to clean and clean the storm introduced from the surrounding road surface first, and the auxiliary filter has the lowest And is installed in the lower space at the other end of the location to filter the overflowing storm water from the purification module when the storm is heavy, so that it is possible to smoothly purify the storm that flows in large quantity during heavy storm.

In addition, a primary storage tank buried in the lower side of the purification module and discharging the purified water purified by the purification module to the ground, and a secondary storage tank buried in the lower side of the auxiliary filter and discharging the stormwater through the auxiliary filter to the ground, It is possible to smoothly discharge the water through the small purification module and the auxiliary filter even in the event of heavy rain by overcoming the limitation of the drainage amount due to the small size of the purification module and the auxiliary filter.

In addition, the primary storage tank and the secondary storage tank are embedded in the lower side of the housing so that the upper surface of the primary storage tank and the upper surface of the secondary storage tank form a continuous plane with the same height so that the inner space of the lower box forms a single depression on the bottom surface of the housing, Most of the dirt having a larger specific gravity is settled in the lower box and is not introduced into the auxiliary filter, so that the dirt can be prevented from flowing out through the auxiliary filter.

Further, the permeable sheet of the storage tank passes through the upper pipe of the upper box and the lower pipe of the lower box, which are connected to each other in order, and the rainwater flowing into the inside of the tank is filtered to slowly permeate the rainwater in the tank into the ground. It is possible to prevent an underground settlement from occurring. In addition, it is possible to prevent the flooding of heavy rain on the upper side of the grating by the drain pipe embedded in the side wall of the housing so that the height of the lower end is equal to the height of the upper surface of the purification module or higher than the upper surface of the purification module.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition to water, which is a major component, fine particles of exhaust gas accumulated on a road surface, dust caused by tire wear, dust caused by abrasion of asphalt, soot or dust floating in the air, etc. Fine pollutants, and other municipal waste. Embodiments of the present invention relate to a compact type superior receiver having a function of purifying non-point contamination of an excellent flowing on a surrounding road surface. Hereinafter, such superior type receivers will be briefly referred to as "compact type superior receivers ".

FIG. 1 is an internal perspective view of a compact type well according to an embodiment of the present invention, FIG. 2 is a front sectional view of the compact type well shown in FIG. 1, and FIG. 3 is a cross- Fig. 4 is a cross-sectional view of the compact type well shown in Fig. 1, and Fig. 5 is an external perspective view of the compact type well shown in Fig. 1-5, the compact type well according to the present embodiment includes a housing 10 embedded in the ground of the road surface, at least one grating 20 installed at the top of the housing 10 and exposed to the road surface, A purifying module 30 located on the left side of the inside of the housing 10, an auxiliary filter 40 located on the right side inside the housing 10, a primary storage vessel 50 buried in the lower side of the purifying module 30, A secondary storage tank 60 buried in the lower side of the auxiliary filter 40 and a drain pipe 70 buried in the side wall of the housing 10.

The housing 10 is formed in the shape of a square pipe having open top and bottom surfaces, and is embedded in the road surface underground, and can be made of a concrete material. The housing 10 is buried in the basement 200 side of the roadside 100 and flows toward the boundary 200 of the roadside 100 to be collected. At least one of the gratings 20 is installed on the open upper surface of the housing 10 so as to be continuous with the inclination of the surrounding road surface, and the gravity flows in from the surrounding road surface. At least one of the gratings 20 may be made of galvanized cast iron or aluminum material. One grating may be provided on the open upper surface of the housing 10 depending on the size of the upper surface opening portion of the housing 10, or several gratings may be provided.

For safety of pedestrians, vehicles, etc., the grating 20 is constructed such that the upper surface thereof is continuous with the surrounding road surface. There is hardly any case where the road surface is perfectly horizontal, and the rain on the road surface flows along the inclination. Thereby, the storm that flows on the circumferential road surface meets the grating 20 and flows down therefrom. The outer wall surface and the slope of the grating 20 cause the rain that flows on the surrounding road surface to flow first to one end of the highest position of both ends of the grating 20 in the oblique direction. If the amount of storm flows on the surrounding road surface is increased due to an increase in rainfall or the like, the area of the grating 20 through which the storm passes is gradually increased due to an increase in the flow rate and the velocity of the storm.

The purifying module 30 is located inside the housing 10 and passes through at least one grating 20 to purify the rainwater flowing into the interior of the housing 10. The purifying module 30 is disposed at a lower space of one end of the highest position of both ends in the oblique direction of at least one of the inner spaces of the housing 10, And is disposed in the left space of the inner space to purify storm water falling into a lower space at one end of at least one of the gratings 20. Accordingly, the purging module 30 first receives the purger from the surrounding road surface and purifies the purger. 1-5 illustrate that the grating 20 is shown horizontally for the sake of simplicity in the present embodiment, but it is constructed so as to have the same slope as the slope of the circumferential road surface, as can be understood by those skilled in the art. have.

Since the rainfall gradually increases, the flow and velocity of the initial storm are small. The initial storm having a small flow rate and flow rate flows downward along the inclination of the surrounding road surface and flows only toward one end of the highest position of the grating 20 and does not reach the other end of the grating 20. Since most of the non-point pollutants on the surrounding road surface are swept away by the initial rainfall having a small flow rate and flow rate and flow into only one end of the highest position of the grating 20, And then flows into the installed purification module 30. Accordingly, most of the non-point pollutants are purified by the purifying module 30. [

6 is an enlarged view of the purifying module 30 shown in Fig. 6 (a) is a perspective view of the purification module 30, and Fig. 6 (b) is a cross-sectional view of the purification module 30. Fig. 6, the purifying module 30 includes a lower box 31 seated in an opening on the upper surface of the primary storage vessel 50, an upper box 32 positioned above the open upper surface of the lower box 31, A lower cover 34 covering the opening of the inner bottom surface of the upper box 32 and a lower cover 34 fixedly attached to the inner bottom surface of the upper box 32. [ An upper lid 36 covering the open upper surface of the upper box 32 and a weight 37 coupled to the upper lid 36. [ Since the purging module 30 is located inside the housing 10 made of a rigid concrete material, the purging module 30 is protected from external impact by the vehicle passing through the road or underpressure of the underground soil. Accordingly, the lower box 31, the upper box 32, the lower lid 33, and the upper lid 35 can be made of a lightweight and inexpensive plastic material.

7 is an enlarged view of the lower box 31 shown in Fig. 7 (a) is a perspective view of the purifying module 30 viewed from above, and FIG. 7 (b) is a perspective view of the purifying module 30 viewed from below. 7, the lower box 31 is formed in a box shape with at least one lower tube 312 protruding upward from the inner bottom surface to receive the drop falling through at least one grating 20 . For example, the lower box 31 may be composed of a rectangular box 311 having an open upper face and four cylindrical lower pipes 312 projecting upward from an inner bottom face of the rectangular box 311.

In the four corner portions of the bottom plate of the rectangular box 311, four circular holes penetrating the bottom plate in the thickness direction are formed. The four lower tubes 312 are four circular tubes whose upper ends extend around the four circular holes of the bottom plate of the rectangular box 311. 7, since the front and bottom surfaces of the lower box 31 are closed, the rain that has flowed into the lower box 31 passes through the side surface and the bottom surface of the lower box 31, I can not go down.

The opening perimeter of the upper surface of the rectangular box 311 is extended to a predetermined length and protrudes from the side surface. The protruded periphery of the upper end of the rectangular box 311 is caught by the upper surface opening of the primary storage vessel 50 in the course of entering the lower box 31 into the upper surface opening of the primary storage vessel 50, 31 may be seated in the upper opening of the primary storage vessel 50. The upper end of the rectangular box 311 is hermetically coupled to the opening of the upper surface of the primary storage vessel 50 by bolt connection or the like. Since the front and bottom surfaces of the lower box 31 are closed and the upper periphery of the rectangular box 311 is sealed to the opening of the upper surface of the primary storage tank 50, 50, it must pass through the lower tube 312 of the lower box 31.

8 is an enlarged view of the upper box 32 shown in Fig. 8A is a perspective view of the upper box 32 viewed from above and FIG. 8B is a perspective view of the upper box 32 viewed from below. The upper box 32 includes at least one upper tube 322 communicating with at least one upper tube 323 of the lower box 31 and a filtration tube 322 formed in a lower surface of the lower tube 31, 323 protrude downward from the lower surface of the lower box 31 to filter out the rainwater from the lower box 31 and discharge it to the primary storage tank 50. For example, the upper box 32 includes a rectangular box 321 having an opened upper face, a filtering box 322 protruding downward from the lower face of the rectangular box 321, And four upper tubes 323.

In the center of the bottom plate of the rectangular box 321, one circular opening is formed through the bottom plate in the thickness direction, and four circular holes are formed in the four corner portions of the rectangular box 321 to penetrate the bottom plate in the thickness direction. The filtration tube 322 is a cylinder in which the periphery of the circular opening at the center of the bottom of the rectangular box 321 extends upward and the extending end thereof is formed in the form of a circular perforated plate. The filtration tub 322 is filled with filter media such as activated carbon, aggregate, coconut, zeolite, and aggregate to purify non-point pollution of the storm. The four upper tubes 323 are four circular tubes whose upper ends extend around the periphery of the four circular holes on the lower surface of the rectangular box 321.

6, the inner circumferential surface of the four lower tubes 312 of the lower box 31 and the outer circumferential surface of the four upper tubes 323 of the upper box 32 are in close contact with each other, The four lower tubes 312 are press-fitted one by one into the four upper tubes 323 of the upper box 32 so that the four upper tubes 323 and the four lower tubes 31 of the upper box 32 The tube 312 may be communicatively coupled in a sealed state. The front and bottom surfaces of the lower box 31 are closed and the upper end of the rectangular box 311 is sealed to the opening of the upper surface of the primary storage tank 50. [ In addition, since the four upper tubes 323 of the upper box 32 and the four lower tubes 312 of the lower box 31 are communicatively coupled in a sealed state, the storages in the housing 10 are separated from the primary storage vessel 50, It is necessary to sequentially pass through the four upper tubes 323 of the upper box 32 and the lower tube 312 of the lower box 31 in order to flow into the lower box 31. [

At the time of the initial storm, the rain falling down to the lower space at one end of the highest position of the grating 20, that is, the space at the side of the purifier module 30, flows into the lower box 31 first. As the rain is continuously lowered, the water level in the housing 10 gradually increases. When the level of the rainwater in the housing 10 becomes higher than the height of the inner bottom surface of the upper box 32, the rainwater in the housing 10 passes through the filtration tube 322 in the direction opposite to the gravity direction, And enters the space of the box 32. In the process of passing the filtration tub 322 in the opposite direction of the gravity direction and flowing into the space of the upper box 32 above the filtration tub 322, suspended matters of excellent surface such as leaves, paper pieces, oil film, The dirt that has passed through the porous lower surface of the filtration tube 322 is filtered by the filter medium 33 in the filtration tube 322.

Accordingly, only the purified water is introduced into the space of the upper box 32 above the filter box 322 by the porous surface of the filter box 322 and the filter material 33 in the filter box 322. The rainwater flowing into the space of the upper box 32 above the filter box 322 passes through the upper pipe 323 of the upper box 32 and the lower pipe 323 of the lower box 31 which are in communication with each other And is discharged to the primary storage tank 50. As described above, according to the present embodiment, by using the structure in which the lower box 31 and the upper box 32 are vertically arranged, By filtering the suspended matters on the surface of the abrasion by the lower surface, the abrasion can be adequately purified by a small filter medium. As a result, the purifying module 30, which plays a role of purifying the stormwater, can be manufactured compactly.

There are many facilities such as gas pipes, power lines, communication lines, etc. in addition to the waterways and sewage pipes in the underground. In order to improve the purification performance of the conventional artificial leather, the conventional artificial leather is provided with a structure in which a plurality of layers are stacked horizontally or vertically and a water channel is formed so that the exterior can be discharged to the outside after passing through the filter media Therefore, the conventional superior receiver has to be manufactured in a large size. Accordingly, in order to install a conventional superior receiver, it is necessary to secure a large space under the road without underground facilities, so that it is difficult to install the conventional receiver. According to the present embodiment, the purifying module 30 can be compactly manufactured, and the housing 10 having the purifying module can be manufactured compactly, so that it can be installed freely in the underground space where many underground facilities exist .

The water level of the rainwater in the housing 10 is gradually lowered. When the level of the rainwater in the housing 10 becomes lower than the height of the inner bottom surface of the upper box 32, some of the rainwater in the space of the upper box 32 above the filter box 322 is communicated with the upper box 32 Through the upper pipe 323 of the upper box 32 and the lower pipe 312 of the lower box 31 to be discharged into the primary storage vessel 50 and then discharged to the outside of the space of the upper box 32 above the filter cylinder 322 Passes through the filtration tube 322 in the gravity direction and is discharged into the inner space of the lower box 31. [ When the level of the rainwater in the housing 10 is further lowered so that the level of the rainwater in the housing 10 becomes lower than the height of the lower surface of the porous wall of the filtering wall 322, all the rainwater in the filtering wall 322 flows in the direction of gravity And falls into the inner space of the lower box 31 below the filter box 322. [ The leaves, paper pieces, oil film, and the like floating on the surface of the excellent surface pass through the filter box 322 in the process of passing the filter paper 33 in the gravity direction and falling into the inner space of the lower box 31 below the filter box 322 And is separated from the surface of the coarse surface and the filter material 33.

There are many very small voids formed in the filter medium by its nature, and the surface voids of such filter media can be blocked by the dirt contained in the rain. Most of the prior art receivers disclosed in Korean Patent No. 10-1195091, No. 10-0536654, No. 10-0597203, etc. have a structure in which a fine-grained filter material passes in the gravity direction, and therefore, The surface of the surface is continuously accumulated or clumped, so that the performance of the filter material gradually decreases. For example, the surface pores of the filter media may be clogged by solid suspended particles such as leaves, paper fragments, or fine particles entangled by the oil film.

According to this embodiment, while the storm is passing through the filtration tub 322 in the direction opposite to the direction of gravity, a part of the floating material such as leaves, paper pieces, oil film, And the remainder is attached to the surface of the filter material 33. As shown in Fig. Since the suspended matter of such an excellent surface rises and falls according to the level of the rainwater, the rainwater passes through the filter media 322 in the process of falling down into the inner space of the lower box 31 below the filter box 322, And is separated from the surface of the coarse surface and the filter material 33. The size of each hole on the lower surface of the filtration tube 322 is formed smaller than the particle size of the filter medium so that the filter medium in the filtration tube 322 does not flow out to the outside of the filtration tube 322.

The dirt having a specific gravity larger than that of water in addition to the suspended matters on the surface of the water can reach the lower surface of the porous tub 322 of the filtration tub 322 along with the flow of the outflow into the filtration tub 322, Lt; / RTI > As described above, the floating matters on the surface of the excellent surface according to the present embodiment are raised or lowered according to the level of the storm water to be separated from the porous surface of the filtration tube 322 and the surface of the filter element 33, The dirt is not deposited on the surface of the filter material on the side from which the storm is introduced due to the difference in the specific gravity, and the dirt is not clogged by the oil film on the surface of the filter material, The deterioration of the purification performance due to the pore clogging is hardly caused.

Even if the surface pores of the filter medium are not clogged by the dirt contained in the storm water, the filtration performance is gradually lowered due to abrasion around the pores of the filter medium in the process of entering and discharging the stormwater through the filter medium 33. Therefore, the more abundant the amount of the air passing through the filter medium 33 at the same time, the more rapidly the wear of the filter medium 33 proceeds, and the filtration performance deteriorates sharply. Korean Unexamined Patent Publication No. 10-1547903 discloses that a conventional superior receiving member adopts a structure in which an excellent permeable medium passes in the opposite direction of gravity but the superior permeable member passes upward through the permeable member So that wear of the filter media is faster than that of the conventional receiver of the conventional downward filtration method as described above.

As described above, some of the rainwater in the space of the upper box 32 above the filtration tube 322 becomes lower than the upper tube 323 of the upper box 32, which are communicated with each other, as the level of the rainwater in the housing 10 becomes lower. And the lower tube 31 of the lower box 31 in order to be discharged to the primary storage tank 50. The rest of the rainwater in the space of the upper box 32 above the filter cylinder 322 passes through the filter cylinder 322 And is discharged to the inner space of the lower box 31. [ The water level in the filtration tube 322 rises and falls integrally with the same level as the water level outside the filtration tube 322. Therefore, when the primary storage vessel 50 is not fully charged, the water level in the primary storage vessel 50 It is much lower than the water level. Therefore, when the primary storage vessel 50 is not fully charged, the superior water pressure in the upper tube 323 of the upper box 32 and the lower tube 312 of the lower box 31 is connected to the filtration tube 322, The water pressure of the rainwater is lower than that of the rainwater.

Thereby, the upper pipe 323 of the upper box 32 and the lower pipe 312 of the lower box 31, which are communicated with each other more than the amount of water passing through the filtration tube 322, The amount of storm water discharged into the room becomes much larger. In the state in which the primary storage vessel 50 is not fully charged, the superiority of the upper pipe 323 of the upper box 32 and the lower pipe 312 of the lower box 31 is directly transferred to the primary storage vessel 50 without any resistance The water pressure of the rainwater in the upper pipe 323 of the upper box 32 and the lower pipe 312 of the lower box 31 hardly exist. In addition, since the rainwater in the primary storage tank 50 is discharged to the ground, it hardly occurs in the case where the primary storage tank 50 is fully charged. Therefore, the amount of the rainwater passing through the filter medium 33 in the gravity direction is insignificant. As described above, according to the present embodiment, the amount of the air passing through the filter medium is remarkably reduced compared with the conventional superior upflow filter system, so that the wear of the filter medium is slowed down and the filtration performance of the filter medium is reduced The performance at that time can be maintained for a long time.

9 is a view showing another embodiment of the upper box 32 shown in Fig. 9, a spiral-shaped protrusion 324 for dividing the lower surface of the filtering cylinder 322 into a plurality of fan-shaped regions protrudes downward so as to touch the inner bottom surface of the lower box 31, And a plurality of holes are formed in the sectoral region between the spokes 324. If the flexible material such as vinyl sheets is contained in the pavement, the flexible dirt may cover the entire lower surface of the filter case 322 and may block the inflow of the filter case 322 while covering the lower surface of the filter case 322.

The space between the lower surface of the filtration tube 322 and the inner bottom surface of the lower box 31 is divided into a plurality of spaces by the spiral projections 324 that divide the lower surface of the filtration tube 322 into a plurality of sector regions Even if the flexible dirt flows into the lower box 31, it flows into only one of the plurality of sector areas on the lower surface of the filter box 322, and the entire lower surface can not be covered. As a result, even if the flexible dirt flows into the lower box 31, the smoothness can be smoothly introduced into the filtration tub 322 through the other fan-shaped regions of the lower surface to which no soft dirt is introduced.

10 is an enlarged view of the lower lid 34 shown in Fig. 10 (a) is a perspective view of the lower lid 34 viewed from above, and Fig. 10 (b) is a sectional view of the lower lid 34. Fig. 10, the lower lid 34 is formed in the form of a circular perforated plate to cover the opening of the inner bottom surface of the upper box 32 corresponding to the outlet of the filtration tube 322, Block outflow of filled filter media. Each opening of the lower cover 34 should be smaller than the particle size of the filter material filled in the filter case 322 in order to block the outflow of the filter material filled in the filter case 322. Since the filter material is not generally formed in the form of a lump and the small pellets are filled in the filter case 322 in the form of a bundle, the flow of the filter material 322 through the filter case 322 May be separated and flow into the space of the upper box 32 above the filter box 322. [ The lower cover 34 serves to block the outflow of such filter media.

11 is an enlarged view of the upper lid 36 shown in Fig. 11 (a) is a perspective view of the upper lid 36 as seen from above, and Fig. 11 (b) is a sectional view of the upper lid 36. Fig. 11, the upper lid 36 is formed in the form of a non-porous flat plate so as to cover the open upper surface of the upper box 32, . The rectangular box 321 of the upper box 32 may be formed in a state in which the upper surface thereof is clogged to prevent the rain that has passed through the grating 20 from falling into the inside of the upper box 32. [ However, if the upper surface of the upper box 32 is clogged, it is not easy to replace or clean the filter media 33 filled in the filter box 322 of the upper box 32.

The upper lid 36 is detached from the open upper surface of the upper box 32 and moved to the outside of the purifying module 30 and then the lower lid 34 is moved to the inside of the upper box 32 It can be separated from the opening of the bottom surface and moved to the outside of the purification module 30. The filter material filled in the filtration tube 322 can be easily exchanged or cleaned while the upper cover 36 and the lower cover 34 are moved to the outside of the purification module 30. As described above, the present embodiment is characterized in that the upper part of the upper box 32 is opened by opening the top box 32 and covering the open upper surface of the upper box 32 with the upper lid 36. [ The filter media 322 can be easily exchanged or cleaned by blocking the falling of the filter media 322 into the interior of the filter case 322.

6, the engaging member 35 is fitted from the lower side of the lower surface of the filtration tube 322 so that a part of the thread protrudes upward from the center hole of the porous lower plate of the filtration tube 322, A nut projecting upward from the center hole of the porous lower plate of the filtration tube 322 and a nut fastened tightly to the upper surface of the lower plate of the filtration tube 322 and a lower cover 34 And a nut fastened to the upper end of the lower lid 34 in close contact with the threaded end of the bolt protruding upward from the center hole of the lower lid 34. Thus, the lower cover 34 can be fixed to the lower surface of the upper box 32 by fastening the nut to the threaded end of the bolt protruding from the center hole of the lower cover 34. [

Further, since the nut is fastened to the thread of the bolt protruding upward from the center hole of the porous lower plate of the filtration tube 322, even if loosening the upper surface side nut of the lower lid 34 to separate the lower lid 34, The bolt inserted into the center hole of the porous lower plate of the bolt 322 does not fall down. The upper cover 36 and the lower cover 34 are separated from each other and the bolts are fixed to the filter case 322 as they are when the filter media packed in the filter case 322 is replaced or cleaned. The upper lid 36 and the lower lid 34 can be reassembled after the media is separated from the lower lid 34 and replaced or cleaned.

The weight 37 is a bolt that is fitted from the lower side of the lower surface of the upper lid 36 and has a threaded end projecting upward from the center hole of the upper lid 36. The metal weight is inserted between the bolt and the upper lid 36, And a nut fastened to the upper surface of the upper lid 36 in close contact with the threaded end of the bolt protruding upward from the center hole of the upper lid 36. The upper cover 35 is made of a light plastic material so that the upper cover 36 is moved to the upper side of the upper box 32 by the flow of the rainwater discharged from the filtering box 322, ). ≪ / RTI > Thus, the weight 37 prevents the upper lid 36 from flowing due to the flow of rain.

The auxiliary filter 40 is formed in the shape of a porous cover so as to cover the lower space of the other end of the lowest position of both ends in the oblique direction of at least one of the inner spaces of the housing 10, As the area of the grating 20 into which the storm flows is increased due to the increase of the flow rate and the flow rate of the storm that is installed in the right space inside the housing 10 shown in the figure, Filter the stormwater falling down into the space below. For example, the auxiliary filter 40 may be formed in the form of a hemispherical shell having a plurality of holes. Since the auxiliary filter 40 serves only to cut off the solid dirt having a size larger than the size of each hole thereof such as a leaf, a swarf, or the like, an initial storm that flows into one end of the grating 20 is blocked by the auxiliary filter 40, The height of the upper end of the auxiliary filter 40 may be designed to be lower than the height of the inner bottom surface of the upper box 32 so that the height of the auxiliary filter 40 is not introduced.

The runoff on the road at the end of the initial storm and at the beginning of the storm contains a very small amount of nonpoint pollutants and may be discharged directly into the ground or the sewer. On the other hand, the short-term heavy rainfall may exceed the capacity of the storm that can be discharged through the purifying module 30. The auxiliary filter 40 can not be discharged to the primary storage tank 50 through the purifying module 30 and can not be supplied with the overflow surplus from the purifying module 30 in an auxiliary manner It plays a role of filtering. Accordingly, the purifying module 30 and the auxiliary filter 40 can smoothly purify the storm that flows in a large amount during the heavy rain. However, since the auxiliary filter 40 only blocks the large-sized dirt and does not purify the poor by using the filter media, in order to allow most of the goodness in the housing 10 to be purified by the purifying module 30, It is preferable to design the size of the auxiliary filter 40 and the size of each hole so that the displacement amount of the auxiliary filter 40 is much smaller than the displacement amount of the purification module 30.

The primary storage tank 50 is buried in the lower side of the housing 10 and discharges the purified water cleaned by the cleaning module 30 to the ground. The secondary storage vessel 60 is buried under the auxiliary filter 40 and discharges the storm that has passed through the auxiliary filter 40 to the ground. Since the purification module 30 and the auxiliary filter 50 are manufactured in a small size by temporarily storing the exudation discharged from the purification module 30 and the auxiliary filter 50 by the primary storage vessel 50 and the secondary storage vessel 60 It can be smoothly drained through the small purification module 30 and the auxiliary filter 50 even in the event of heavy rain.

The primary storage vessel 50 and the secondary storage vessel 60 are connected to the housing 10 such that the upper surface of the primary storage vessel 50 and the upper surface of the secondary storage vessel 60 form a continuous plane at the same height, As shown in Fig. The purifying module 30 is seated in the upper opening of the primary storage vessel 50 so that the inner bottom surface of the lower box 31 is positioned lower than the upper surface of the primary storage vessel 50 as described above. The periphery of the lower opening of the auxiliary filter 40 is attached to the periphery of the upper surface opening of the secondary storage tank 60 such that the auxiliary filter 40 protrudes from the upper surface of the secondary storage tank 60. Accordingly, the inner space of the lower box 31 forms the only depression on the bottom surface of the housing 10, and most of the dirt having a specific gravity larger than that of the water is settled in the lower box 31, As shown in Fig. As a result, most of the dirt having a size smaller than the size of each hole of the auxiliary filter 40 is settled in the lower box 31 and is not introduced into the auxiliary filter 40, Can be prevented.

The primary storage tank 50 is composed of a rectangular box type tank 51 buried in the lower side of the purifying module 30 and a water permeable sheet 52 covering the opening portions of the side surface and the bottom surface of the tank 51. The upper surface of the tank 51 is formed in a rectangular shape in which the lower box 31 of the purification module 30 can be seated, and each of the four side surfaces and the lower surface is formed in a framework shape. The permeable sheet 52 covers the upper and lower tubes 323 and 323 of the upper box 32 and the lower box 31 communicating with each other by covering the openings of the side surface and the lower surface of the tank 51 Passes through the tank 51, is filtered and discharged to the ground. The permeable sheet 52 is generally made of a nonwoven fabric material excellent in water permeability and permeates slowly into the ground in the tank 51, thereby preventing occurrence of underground settlement due to abrupt inflow of storm water.

The secondary storage tank 60 is composed of a rectangular box type tank 61 buried in the lower side of the auxiliary filter 40 and a water permeable sheet 62 covering the openings of the side surfaces and the bottom surface of the tank 61. The upper surface of the tank 61 is formed in the shape of a rectangular plate having an opening through which the lower opening of the auxiliary filter 40 is adhered, and each of the four side surfaces and the lower surface is formed in the form of a frame. The permeable sheet 62 covers the openings of the side surface and the bottom surface of the tank 61 and passes through the auxiliary filter 40 to filter the storm that has flowed into the tank 61 and discharges it to the ground. The permeable sheet 62 is made of a nonwoven fabric like the permeable sheet 52 of the primary storage tank 50 and slowly permeates the oil in the tank 61 into the ground to prevent underground settlement from being caused by abrupt inflow of oil .

The primary storage vessel 50 and the secondary storage vessel 60 are formed at the same height so that the lower surface of the primary storage vessel 50 and the lower surface of the secondary storage vessel 60 form a continuous plane at the same height as their respective upper surfaces. One side of the primary storage vessel 50 and one side of the secondary storage vessel 60 are provided so as to be in contact with each other and the other three sides of the primary storage vessel 50 and three sides of the secondary storage vessel 60 are provided with crushed stone, The crushed stone layer 300 is formed. A sand layer 400 is formed under the lower surface of the primary storage vessel 50 and a lower surface of the secondary storage vessel 60 and a crushed stone layer 300 is installed under the sand layer 400. The sand layer 400 serves to form a horizontal ground surface so that the lower surface of the primary storage vessel 50 and the lower surface of the secondary storage vessel 60 can be stably supported by the lower surface.

The drain pipe 70 is buried in the side wall of the housing 10 and connected to the sewer so that the height of the lower end of the drain pipe 70 is equal to the height of the upper surface of the purifying module 30 or higher than the upper surface of the purifying module 30. The stormwater discharged through the drain pipe (70) is sent to the sewage treatment plant or the river through the sewage pipe. Since the auxiliary filter 40 also has a limitation on the amount of water that can be filtered through the pores of the auxiliary filter 40, the superiority of the overflow from the purification module 30 and the auxiliary filter 40, Is discharged to the sewer through the drain pipe (70) embedded in the side wall of the housing (10). The purifying module 30 and the auxiliary filter 40 are firstly cleaned by the purifying module 30 and then filtered by the auxiliary filter 40 in accordance with the amount of water flowing into the housing 10, Is discharged to a sewer pipe through a drain pipe (70) buried in the side wall of the housing (10), thereby preventing the flooding of the flood to the upper side of the grating (20).
