The present invention relates to an initial excellent induction pipe for a river bridge, an initial excellent induction method using the induction pipe, a nonpoint pollution reduction facility having the initial excellent induction pipe, and a reduction method. More specifically, the vertical drainage pipe is made small so as to process only the initial rainwater, and the initial rainwater is transferred to the land part to be introduced into the natural type abatement facility, and the subsequent excess water flows directly to the river through the overflow pipe to secure economical efficiency and treatment. The present invention relates to an initial excellent induction pipe for river bridges that can optimize efficiency.

Water pollution sources are divided into point pollution sources and non-point pollution sources. Point pollution sources are mainly used for monitoring the occurrence area and generation amount such as domestic sewage generated in general households or business areas, industrial wastewater discharged from factories, animal wastewater generated in large- This is a relatively easy subject and is the main object of sewage disposal.

On the other hand, non-point pollution source refers to drainage from agricultural drainage, mine waste water, livestock wastewater from small-scale livestock facilities, living sewage or forest in rural areas without sewerage, and these pollutants are relatively dependent on natural treatment due to less contribution of pollution.

Emphasis is placed on non-point sources, non-specific pollutants, surface pollutants, mobile pollutants, and other pollutants. Unlike point pollutants having specific discharge routes, non-point pollutants are unspecified, such as urban road drains or agricultural drainage. Refers to a location or area that generates nonpoint pollutants through an exhaust path.

Aquaculture facilities, transportation facilities, maintenance or disposal facilities, simplified processing facilities for enriched fisheries products, photo processing facilities, etc., which have been renamed as 'other water pollution sources' in the 'Specified Facility' under the Water Quality Protection Law, , Product yard, land change area, and other facilities.

Non-point pollutants are mainly pollutants that run out along with surface rainfall runoff when they are exposed to rain. These include fertilizers, pesticides, soil sprinkling plants, housing spills, traffic pollutants, dust and garbage in urban areas, Residues, and air pollutants that have fallen on the surface of the earth.

Therefore, rainwater (rainwater runoff) containing all pollutants is actually the main nonpoint source. Since non-point pollutants usually flow out with a lot of rainfall, there is a large difference between daily and seasonal emissions, and it is difficult to forecast and quantify, and it is affected by weather conditions, geology, and topography which are difficult to manure.

The point pollution sources such as domestic sewage are steadily decreasing due to the establishment of basic environmental facilities, but the nonpoint pollution sources are continuously increasing due to the improvement of land use. In particular, the impact of non-viscous salts on water quality is predicted to reach 65 ~ 70% by water sector in 2015, and active management of non-point pollution sources is required.

In 2007, the government revised and amended the 'Law on Water Quality and Aquatic Ecosystem Correction' to select and expand objects to be installed in nonpoint pollution abatement facilities.

As of the end of 1999, as a result of the "Non-point Source Pollution Research Service" (conducted in June 2000) on the upper stream of the Paldang Dam in the Han River, the main water source of the metropolitan area residents, The pollutant loads generated from point sources such as industrial wastewater and livestock wastewater were 804.4%, 130,650t / year, and the pollution load from nonpoint pollution sources was 19,3193t / year, which was 19.6%.

In addition, the non-point source pollution source was estimated to be 44.5% of the total discharge load (BOD standard), and nonpoint source pollution was found to have a significant influence on water pollution. The Geum River, Nakdong River and Youngsan River . Therefore, as the regulations for point sources with regulatory standards are continuously strengthened and environmental facilities are expanded, the impact of non - point pollution sources on water quality will gradually increase.

As a countermeasure for reducing pollution, conventionally, in order to reduce pollution, the road surface drainage in an urban area is provided with a storage tank to allow the pollutants generated due to the initial rainfall to be settled and discharged, · Agricultural drainage, which contains a large amount of agricultural chemicals, was installed in a reservoir, a wetland purification facility, and aquatic plants to prevent direct influx into the river.

However, such a countermeasure would be to treat only the initial rainfall, which is the actual nonpoint source pollutant discharged with all the pollutants, by continuously treating the rainwater after a certain period of time when the concentration of the pollutant decreases, There is a problem that the maintenance cost rises. Therefore, a nonpoint pollution abatement facility with proper efficiency and economical efficiency was required for the initial runoff containing the majority of nonpoint pollutants.

In addition, non-point pollution abatement facilities such as infiltration ditches or sand filtration facilities should be installed off-line (separation of abatement facilities from existing waterways) in order to improve the stability of the abatement facilities and the water treatment efficiency. The separation facility corresponds to a flow splitter.

In the United States, it is designed to be made into a corrugated form. However, it is not suitable for the domestic repair system, it is disadvantageous to the construction and maintenance, and the abatement facility can not exert its function because there is no installation standard in Korea.

Particularly, in the case of bridges passing through rivers, nonpoint pollutants flow directly into rivers and the installation of the abatement facilities is further needed. Fig. 1 shows a side view of a conventional excellent guiding tube for bridges. As shown in FIG. 1, in the case of the conventional long bridge 5, it is necessary to transfer the entire height of the bridges to the abatement facility installed on the land side through the water pipe 8, so that the diameter of the water pipe 8 becomes larger (The maximum diameter of the drain pipe 8 being currently installed is about 800 mm), problems such as an increase in load, an increase in construction cost, and a deterioration of aesthetics occur.

Further, in the case of the conventional long bridge 5, the apparatus type reduction facility 9 is installed in the bridge pier 6 itself to remove such non-point pollution. Fig. 2 shows a side view of the device-type facility 9 on the side of the bridge pier 6 in the prior art. As shown in FIG. 2, it can be seen that the device-type abatement facility 9 is installed on one side of the bridge pier 6 to reduce nonpoint pollutants on the road surface of the bridge 5. However, such a device type has a problem that the efficiency of the reduction is low and installation and maintenance are difficult. Therefore, a countermeasure against this problem is needed.

Therefore, the initial storm 1 flowing into the sewage pipe 130 and discharged is stored in the pre-treatment tank 200. The volume of the pretreatment tank 200 corresponds to about 20 to 30% (preferably 25%) of the total water treatment capacity (WQv) for contaminant removal.

The initial ooze (1) flowing into the pretreatment tank (200) is stored in the pretreatment tank (200), and a part of the contaminants is settled downward. Therefore, suspended solids such as soil particles and refuse contained in the initial storm 1 are primarily removed, thereby increasing the efficiency of reducing non-point pollution.

Figure 7a shows a cross-sectional view of a non-point pollution reduction facility having an initial excellent induction pipe 100 for the river bridge in the view point according to the first embodiment of the present invention. And, Figure 7b is a cross-sectional view of a non-point pollution reduction facility having an initial excellent induction pipe 100 for the river bridge at the end portion according to the first embodiment of the present invention. 8 illustrates a cross-sectional view of the penetration trench 300 according to the first embodiment of the present invention.

As shown in FIGS. 7A and 7B, it can be seen that the penetration trench 300 has a specific trench length L and a depth d. In the concrete example, the depth of the infiltration ditch 300 is about 1 to 2.5 m, and a kind of a reservoir filled with aggregate is filled with the initial outflow 1 introduced from the pretreatment tank 200 for 48 hours (within a maximum of 3 days) And gradually penetrates into the soil layer.

In addition, as illustrated in FIGS. 7A and 7B, a partition wall 230 is provided between the penetration trench 300 and the pretreatment tank 200, and two injection holes 210 are disposed below the partition wall 230. It can be seen that it is formed. Therefore, the initial rainwater 1 stored in the pretreatment tank 200 gradually flows into the infiltration ditch 300 by the inflow hole 210, and is then desalinated and infiltrated into the lower part of the infiltration ditch 300.

In addition, as shown in FIG. 8, the penetration trench 300 may include a top portion composed of a residue layer 330, a stop portion composed of a gravel layer 320, and a bottom portion composed of a sand layer 310. The filter fibers 340 are provided between the gravel layer 330 and the gravel layer 320 and between the gravel layer 320 and the sand layer 310 and on the side surfaces of the gravel layer 320 and the side surface of the gravel layer 330 do. The construction of the infiltration ditch 300 is performed by first excavating a location where the infiltration ditch is installed and laying a sand layer 310. The filter fiber 340 is laid on the sandbed layer 310. The gravel layer 320 is laid on the filter fiber 340, The filter fiber 340 is applied to the upper portion of the filter 333, and then the upper layer 333 is laid on the upper portion of the filter fiber 340.

In the concrete example, the diameter of the gravel blocks forming the gravel layer 330 is about 2.5 cm on average, the diameter of the gravel constituting the gravel layer 320 is about 4.0 cm on average, The average diameter is about 0.5 cm. The volume of the infiltration ditch 300 is a value obtained by dividing the porosity of the aggregate filled in the infiltration ditch 300 by the total water quality treatment capacity WQv.

In addition, it can be seen that the initial excellent 1 overflowed in the pretreatment tank is introduced into the upper side of the penetration groove 300 as shown in FIGS. 6A and 6A. According to the flow rate and the flow rate of the initial rainwater (1) flowing into the upper side, some of the freshwater and infiltration to the lower side of the penetration groove 300, the freshwater and the initial rainwater (1) that did not penetrate into the penetration groove 300 is 6a As shown in FIG. 6B, the vegetation zone 400 is discharged to the existing water channel 20.

The vegetation zone 400 is connected to the rear of the infiltration ditch 300 and the vegetation water is planted so that only the excess capacity exceeding the initial inflow is introduced into the upper part of the infiltration ditch 300 and discharged to the existing waterway 20. In addition, a part of the water is infiltrated into the bottom soil layer of the vegetation zone 400 or flows into the existing water channel 20 after filtration by vegetation.

9 is a side cross-sectional view of the connection portion between the pretreatment tank 200 and the penetration groove 300 according to the first embodiment of the present invention.

That is, the initial rainwater 1 flows into the aquarium 570 through the inlet hole 210, and the initial rainwater 1 overflowing from the aquarium 570 flows into the treatment vessel 510. Also, the initial rainwater 1 overflowing from the pre-treatment tank 200 may be introduced into the air tank 570 of the sand filtration tank 500 instead of the input hole 210. The provision of such a small-sized tank 570 is advantageous in that if the initial void 1 overflowing from the input hole 240 or the entire lower side is directly introduced into the upper portion of the sand layer 520 of the treatment tank 510, It is because.

In addition, as shown in Figure 13a and Figure 13b, the injection hole 240 is installed in the inlet tube 250, it can be seen that the inlet pipe 250 is installed in the hole hole plate 260 for removing foreign matter. A plurality of holes are provided in the perforated meniscus plate 260 for removing foreign substances to prevent floating substances such as soil particles and trash sedimented in the lower part of the front side of the apparatus from flowing into the sand filtration tank 500, (250) is prevented from being clogged.
