TECHNICAL FIELD The present invention relates to the field of environment, and more particularly, to a system for treating rainwater associated with a nonpoint source by purification, infiltration, or the like.

Sources of pollutants are classified into point sources and nonpoint sources based on whether their outlets are specified in a specific location.

The point source is a case where the pollutant is discharged through the outlet of a specific place, and may include a sewage treatment plant, an industrial wastewater treatment plant, livestock, manure, and leachate.

Non-point source is a case where the discharge port of pollutants cannot be specified, such as pollutants accumulated on the top of roads and bridges, fine dust such as vehicle exhaust gas and tires, and pollutants accumulated on the surface of construction sites such as road farmland For example, these pollutants are a representative cause of water pollution because it is introduced into the stream with rainwater (rain water) during rainy weather.

Among these, the most important area is the latter non-point source field, and there is an urgent demand for devising a system for efficiently purifying and treating it.

14 is a side cross-sectional view showing a conventional stormwater treatment facility.

As shown, by covering the packaging portion 2 made of a permeable material such as a non-woven fabric on the surface of the skeleton-forming structure (1), it is embedded in the ground, thereby forming a temporary storage space of rainwater.

Rainwater containing contaminants enters the stormwater treatment facility through the inflow path (3) and is temporarily stored, and then penetrates the ground through the packing unit (2) as time passes, and contaminates the size that cannot penetrate it. The substance accumulates inside the stormwater treatment plant.

If the size of the storm water treatment facility is larger than the predetermined size so that a large amount of storm water can be stored, it is possible to prevent the flooding of the earth's surface during the rainy season. It is expected to be.

However, the conventional stormwater treatment facility having such a structure has the following problems.

First, cleaning and other maintenance is very inconvenient.

Pollutants that do not penetrate the inside of the packing unit 2 forming the storm water treatment facility are deposited. For the cleaning and other maintenance thereof, the facilities must be dismantled again, which is very inconvenient.

Second, it is difficult to achieve the planned performance.

Because of the above reasons, cleaning and other maintenance work is not done well, even if done so very long intervals, it is very difficult to achieve the planned storage performance, permeability performance, etc. at the time of construction.

Third, since there is no distinction between initial and sustained excellence, efficient purification is impossible.

Pollutants constituting the nonpoint source are washed in rainwater during rainfall and flow into stormwater treatment facilities. Looking at the distribution of pollutants contained in rainwater, the pollutants are concentrated only in the case of initial stormwater, In the case of sustained rainfall afterwards, it can be seen that there are almost no contaminants.

That is, since most of the contaminants such as the upper surface of the road are washed with the initial rainwater, the sustained rain afterwards hardly contain the pollutants.

By the way, the conventional stormwater treatment facility has a configuration that does not consider such characteristics of stormwater, it has a problem that it is not efficient.

Fourthly, it does not take advantage of relatively clean sustained rainfall.

As described above, the sustained rainwater is a clean state that contains little contaminants, and therefore, when a means for separating and storing the rainwater from the initial rainwater can be used, it can be used as a sufficiently useful use.

Conventional rainwater treatment facility has been pointed out the above problems because it takes only the configuration corresponding to the infiltration tank 300 of the above components, in the case of the present invention rainwater separating unit 100 to separate the initial rainwater and the continuous rainwater, Among them, it is characterized in that it further comprises a settling tank 200 to clean the granular contaminants contained in the initial rainwater in advance, which is to achieve the following effects.

Third, the rainwater separating unit 100 preferentially separates the rainwater into the initial rainwater (contaminants are included) and the sustained rainwater (contaminants are hardly included), thereby enabling efficient purification as described below.

Hereinafter, embodiments of each component of the stormwater treatment system according to the present invention will be described in detail.

The rainwater separating unit 100 is configured to separate the initial rainwater flowing from the rainwater inlet 101 into the initial rainwater flow path 110 and the continuous rainwater flows into the sustained rainwater flow path 120 by the monthly flow. Regardless of which, Figs. 2 and 3 show preferred embodiments of these.

That is, the embodiment of the rainwater separator 100 shown in Figures 2 and 3, the rainwater flow inlet flows from the rainwater inlet 101 to the initial storm flow path 110 to the initial storm flow path guide portion (a); A partition wall 140 formed to have a predetermined height so as to spatially separate the initial storm flow path guide part a and the continuous storm path 120 and to make the continuous storm run over; It is configured to include.

In such a configuration, the initial rainwater having a low flow rate and flow rate is blocked by the partition wall 140, and flows to the initial storm flow path 110 side through the initial storm flow path guide part a, and the continuous rainwater having a large flow rate and flow rate is partition wall ( Overflow 140 flows to the continuous storm flow path 120 side.

In order to smooth the flow, as shown in FIG. It is preferable to take a structure in which the partition wall 140 is inclined so that the curved degree of the guide portion a becomes an obtuse angle.

Hereinafter, a preferred embodiment of the settling tank 200 will be described with reference to FIGS. 4 to 10.

Precipitation tank 200 in the stormwater treatment system according to the present invention is any structure that can remove particulate contaminants by precipitation before rainwater flows into the infiltration tank 300, as shown in Figure 4 or less An initial settling tank 210 in which an initial settling tank rainwater inlet 211 and a rainwater storage space are formed, and an initial settling tank rainwater outlet 212 is formed at the side; A gate 220 installed to open and close the initial settling tank rainwater outlet 212; A gate opening and closing means 230 configured to open the gate 220 only when the level of the initial settling tank 210 is greater than or equal to a predetermined height; A cyclone separator 240 connected to the initial precipitation tank storm water outlet 212 and configured to purify the rainwater introduced by the cyclone method and discharge the purified water through the purification water outlet 201; A cyclone settling tank 250 installed under the cyclone separator 240; It is more preferable to comprise.

First, the operation principle of the cyclone separator 240 will be described.

Figure 5 is a perspective view showing the configuration of an embodiment of the cyclone separation device 240 applied to the present invention, the dotted line arrow shows the flow of rainwater, the solid arrow shows the flow of particulate contaminants such as sand, gravel.

As shown, the cyclone separator 240 has a conical body portion 241 is formed so that the flow space of the rainwater is formed therein, and gradually decreases as the area of the longitudinal section toward the lower side; A separator device rainwater inlet 242 formed on the side of the conical body portion 241 and formed to have an eccentric flow of rainwater flowing in; A separator purifying water outlet 243 formed above the conical body portion 241; A contaminant contaminant outlet 244 formed below the conical body portion 241 and formed to discharge contaminants into the cyclone precipitation tank 250; It is configured to include.

Since the rainwater inlet 242 of the separator is formed to have an eccentric flow of the rainwater flowing therein, when the rainwater including granular contaminants enters the rainwater inlet 242 of the separator with a predetermined water pressure, the conical body portion 241 is formed by centrifugal force. It flows while forming a vortex inside.

At this time, the granular contaminants such as sand and gravel gradually descend to precipitate in the cyclone sedimentation tank 250 through the separator contaminant outlet 244 (solid arrow), and the rainwater separated from the granular contaminants gradually rises to purify the separator. It flows out through the outlet 243.

This embodiment of the sedimentation tank 200 in the stormwater treatment system according to the present invention uses the principle of the cyclone separation device 240 as described above.

That is, the rainwater introduced through the initial precipitation tank rainwater inlet 211 is once stored in the initial precipitation tank 210, when the flow rate of the rainwater is increased to increase the water level of the initial precipitation tank 210, precipitation tank rainwater outlet 212 ) Is closed by the gate opening and closing means 230, the rainwater flowing in with a predetermined water pressure is purified by the cyclone separator (240).

The granular contaminants separated by the cyclone separator 240 are precipitated in the cyclone precipitation tank 250, and the rainwater purified by this is discharged through the purified water outlet 201.

In order to purify by the cyclone separator 240, the rainwater flowing into the cyclone separator 240 is required to have a certain pressure or more, in this embodiment, 'the hydraulic pressure of the fluid stored in the constant space is proportional to the water level. In view of the principle, the gate opening and closing means 230 configured to open the gate 220 only when the water level of the initial settling tank 210 is higher than a predetermined height, the water pressure required for the operation of the cyclone separator 240 The biggest technical feature is that it is secured by '.

That is, at the level where the purification operation by the cyclone separation device 240 is impossible, the gate 220 is maintained in a closed state. The gate 220 is opened to allow rainwater to flow into the cyclone separator 240.

As such, when constructing the rainwater treatment system using the sedimentation tank 200 to which the cyclone separator 240 is applied, the following effects can be obtained.

First, it is possible to obtain a large amount of precipitation in a very short time.

Second, since the function of the cyclone separator 240 is to be exerted in proportion to the water pressure of the rainwater flowing in, within a certain range, as the flow rate of rainwater increases, it is possible to obtain a purification effect by more excellent precipitation.

Third, even when the flow rate of rainwater is rapidly increased to float the contaminants deposited in the lower portion of the settling space, it is possible to refine the cyclone separation device 240, it is possible to expect a more certain purification effect.

The cyclone separation device 240 may be any structure that can achieve an operation effect that satisfies the object of the present invention by the above principle. In FIG. 5, an excellent flow space is formed therein, and an area of the longitudinal section is Conical body portion 241 is formed to gradually decrease toward the lower side; A separator device rainwater inlet 242 formed on the side of the conical body portion 241 and formed to have an eccentric flow of rainwater flowing in; A separator purifying water outlet 243 formed above the conical body portion 241; A contaminant contaminant outlet 244 formed below the conical body portion 241 and formed to discharge contaminants into the cyclone precipitation tank 250; An embodiment of the configuration is shown.

In the case of adopting the cyclone separator 240 having such a configuration, as shown in FIG. 7, it is preferable that the cyclone separator 240 is mounted on the cyclone separator mounting box 260.

Here, the cyclone separator installation box 260 is installed on the upper side of the cyclone settling tank 250, and the mounting hole 261 of the cyclone separator 240 is formed in the core portion, the initial settling tank rainwater outlet 212 on one side Take the configuration in which the mounting box rainwater inlet 262 in communication with the formed.

In this case, the cyclone separator device mounting box 260 may be installed above the cyclone settling tank 250, and the cyclone separator device 240 may be installed in the cyclone separator device mounting box 260. It is preferable in terms of facilitating the manufacture, transportation, assembly and maintenance of the product.

Hereinafter, an embodiment of the gate opening and closing means 230 will be described.

The gate opening and closing means 230 may be configured to open the gate 220 only when the water level of the initial settling tank 210 is higher than or equal to a predetermined height in order to supply rainwater having a predetermined pressure or more to the cyclone separator 240. It doesn't matter.

That is, by installing a sensor for measuring the water level of the initial settling tank 210 and the method of controlling the opening and closing of the gate 220 by the signal of the sensor, to float the buoy in the rainwater stored in the initial settling tank 210 and the All of the methods of controlling the opening and closing of the gate 220 by vertical driving can be adopted, and FIGS. 4 and 6 illustrate embodiments of the latter method.

That is, the gate opening and closing means 230, as shown in Figure 4, 6, buoy 231 is installed to float by the rain received in the initial settling tank 210; A connector 232 connecting the buoy 231 and the gate 220; It may be implemented by a configuration that includes.

In this case, when the water level of the initial settling tank 210 increases due to the increase of rainwater flowing in, the buoy 231 floating by the rainwater moves upward, and the gate is connected to the buoy 232 connected to the buoy 231. 220 is opened, and rainwater having a water pressure corresponding to the water level at the time of opening is introduced into the cyclone separator 240.

The connector 232 of the gate opening and closing means 230 is connected to the buoy 231 and the gate 220, and any configuration that can perform the above action, but any change in the water level of the initial settling tank 210 and this Since the positional change of the buoy 231 is very fluid, it is preferable that the buoy 231 be formed of a flexible material such as yarn in terms of durability of the structure.

In order for the opening and closing operation of the gate 220 to be more clearly performed by the vertical movement of the buoy 231 according to the change in the water level of the initial settling tank 210, the gate (guide) to guide the vertical movement of the buoy 231. It is preferable to take the structure in which the buoy guide part 270 is formed above 220.

The buoy guide portion 270 may be any structure as long as it can guide the up and down movement of the buoy 231, and in FIG. 6 and 10, the rain inlet hole for introducing the rainwater stored in the initial settling tank 210 ( 271 is formed, the guide hole 272 of the buoy 231 is formed therein, and the embodiment is mounted to the wall surface of the initial settling tank 210 by the coupling member 273.

As described above, in order to facilitate the cleaning of the cyclone settling tank 250 and the like when taking the configuration of entering the initial settling tank 210 to perform cleaning or other maintenance, the initial settling tank 210 is illustrated in FIGS. 4 and 6. And a cyclone settling tank inlet 251 is formed in the partition 203 partitioning the cyclone settling tank 250, and the cyclone settling tank gate 252 for opening and closing the cyclone settling tank inlet 251 is provided. desirable.

On the other hand, in order to properly respond to various changes in the flow rate of the rain, as shown in Figures 8, 9, 10, the gate 220, the gate opening and closing means 230 and the cyclone separating device 240 is a plurality of Set (A, B, C) is formed, it is preferable that the plurality of gate opening and closing means 230 has a configuration formed to sequentially open the plurality of gates 220 as the level of the initial settling tank 210 increases. .

For example, when three sets (A, B, C) are installed, the cyclone separator 240 is effective to open and operate the gate 220 only when a certain water pressure or more, one cyclone separator 240 By the opening of one gate 220 to operate only one set (A) at the level of effective purification, and two sets of cyclone separators 240 at the effective level It is desirable to allow only A, B) to operate, and to allow all three sets (A, B, C) to work until the three cyclone separators 240 reach an effective level.

For this purpose, the sequential opening structure of the plurality of gates 220 may be implemented by various methods, and in the case of using the buoy 231 and the connector 232 of the flexible material, as shown in FIG. 6. Likewise, the length of the connector 232 corresponding to each of the three gate opening and closing means sets 230A, 230B, and 230C may be different.

That is, in the case of the first opening, the gate connected to the connector 232A of the shortest length is opened, in the case of the second opening, the gate connected to the connector of the shortest length 232B is opened, and in the case of the third opening, The gate connected to the long connector 232C is opened.

Hereinafter, the Example of the penetration tank 300 is described.

In addition, the penetration tank skeleton forming portion 310 buried in the ground; It is installed to cover and protect the penetrating tank skeleton forming portion 310, and prevents the outflow of particulate contaminants, but the water-permeable packaging portion 320 formed by a water-permeable material to allow free discharge of rain; Take a configuration that includes

The penetrating tank skeleton forming unit 310 may be any structure as long as it forms a temporary accommodation space having excellent rainwater, and allows the permeable packaging unit 320 to maintain a certain shape, and facilitates production and maintenance. In order to achieve this, it is preferable to take a prefabricated structure by a plurality of blocks as shown in FIG.

Hereinafter, with reference to the penetration tank 300, an embodiment of the sustained storm flow path 120 branched by the rainwater separating unit 100 will be described.

As described above, since the continuous rainwater contains almost no contaminants, it does not need to be introduced into a separate purification device such as a sedimentation tank, and as described below, the efficiency of the overall rainwater treatment system can be improved. Can be.

First, as shown in FIG. 12, the continuous rainwater flow path 120 branched from the rainwater separator 100 may be separately connected to the penetration tank 300.

In this case, the initial rainwater containing contaminants among rainwater is introduced into the penetration tank 300 through the settling tank 200, and the continuous rainwater containing no contaminants is allowed to enter the penetration tank 300 without passing through the precipitation tank 200. , While faithfully performing the initial rainwater purification, there is an advantage that the precipitation tank 200 does not occur even when the amount of rainwater is large, such as the rainy season.

In the case of the infiltration tank 300, the packing part 320 is formed by a permeable material (nonwoven fabric, etc.) so that rainwater can flow out to the outside, whereas in the case of the storage tank 400, the rainwater is impermeable so that the outside does not leak out. There is a difference that the packaging part 420 is formed by a material (vinyl or the like).

In addition, in the case of the reservoir skeleton forming portion 410, as in the case of the penetration tank skeleton forming portion 310, it is preferable to take a prefabricated structure by a plurality of blocks in order to facilitate the convenience of production, maintenance and the like. .

As shown in FIG. 13, when the storage tank 400 is installed as a stacked structure on the upper part of the penetration tank 300, it requires less space than when installing both as separate structures. There are advantages in that both structures can be installed by work.

Third, when the external drain pipe 130 is located in the vicinity of the storm water treatment system, as shown in FIG. 1, the continuous rainwater flow path 120 branched from the rainwater separator 100 is directly connected to the external drain pipe 130. The structure can be taken.

In this case, since only the continuous rainwater that does not contain the pollutant flows to the external drain pipe 130, there is an advantage that it can be discharged as it is to the river.

Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.

The present invention provides a rainwater treatment system having a structure that enables easy cleaning and maintenance, and can effectively exhibit the planned performance.
