Description

{Dam using gabion and Apparatus for water treatment using gabion dam and Aquifer storage and recovery system}

The present invention relates to a water treatment apparatus using a gabangtae intake beam, a gabangtae intake beam, and a basement aquifer brewing tank, and more particularly, to prevent eutrophication of river water by allowing the passage of water and fine soil to a certain level to suppress deterioration of the water quality of river water. In addition, the present invention relates to a water treatment system using a gabion aquifer intake beam that can purify river water in connection with an underground aquifer embedding tank, and a gabion aquifer intake beam and a subterranean aquifer recharge tank.

Beams are installed in rivers to secure agricultural water and prevent floods. Before modern times, beams were constructed using logs and soil, but most of the modern beams use concrete structures. Beams made of concrete structures can be prevented from being damaged by flooding or turbulence, and have the advantage of stably storing a large amount of river water.

However, since the beam of the concrete structure is made of an impermeable material, various problems arise. As water and fine soil do not pass through, the soil transferred from the upstream side is deposited on the bottom of the beam, causing dryness. In addition, the water quality deteriorates due to stagnation of organic pollutants, and the ecological environment is disturbed due to the disconnection of the aquatic ecosystem between upstream and downstream.

The unit gabion consists of a mangtae and a filling material filled in the net, and the filling material may be a natural stone or crushed stone.

The unit gabion for purification is composed of a net and a porous carrier filled in the net, and the porous carrier provides a space for aerobic microorganisms to grow and filters contaminants contained in river water. In addition, the unit gabion for purification is composed of an upper gabion and a lower gabion, and a semi-cylindrical space is provided at each facing part of the upper and lower gabions, and when the upper and lower gabions are combined, a cylindrical space is completed, It is possible to insert and install the perforated collecting pipe in the cylindrical space.

The heat of the unit gabion for purification in which the perforated collection pipes are arranged may be located at the bottom of the gabion intake beam.

The present invention proposes a gabion-based beam. In addition, the present invention proposes a technology for purifying river water stored in the beam by linking a gabion-based beam and an underground aquifer recharge tank.

The beam according to the present invention is formed by constructing a plurality of gabions. That is, the gabion is a method in which the beam is formed by replacing the conventional concrete structure. As gabions are arranged across the river to form beams, and river water is confined by the gabions, some of the river water confined by the gabions can pass through the gaps between the stones of the gabions. . Not only river water, but also fine-sized soil can pass through the gaps between the stones.

As part of the freshwater in the gabangtae intake can pass through the gabangtae intake, it is possible to induce a continuous flow of river water, thereby preventing eutrophication due to stagnation of river water. In addition, as the fine soil transferred from the upstream side also passes through the gabion intake pipe, it is possible to prevent the river from becoming dry by suppressing the accumulation of fine soil in the river bed in the gabion intake pipe.

In this way, the eutrophication and drying of river water can be suppressed through the basic construction of the gabion-tae intake beam. The present invention additionally proposes a configuration for purifying river water in addition to suppressing eutrophication and drying of river water through the basic configuration of a gabion water intake beam. The purification of the river water in the gabion water intake is accomplished by a porous carrier and an underground aquifer recharge tank. In other words, it is possible to prevent river water from being contaminated primarily due to congestion through the basic construction of the gabion water intake beam, and to purify the river water through a porous carrier and an underground aquifer tank.

In the provision of a porous carrier for purifying river water and a subterranean aquifer tank, the porous carrier is provided in the gabion tank, and the subterranean aquifer tank is connected to the gabion tank via a collection pipe.

The porous carrier filters pollutants contained in the river water into the river water in the gabion and provides a space for aerobic microorganisms to grow so that organic pollutants in the river water are decomposed by the aerobic microorganisms.

The subterranean aquifer brewing tank receives river water in the gabion basin through a collection pipe and reduces assimilable organic carbon in the river water through the subterranean aquifer recharge process. Anabolic organic carbon is a major source of carbon for microorganisms, and the reduction of anabolic organic carbon means that the growth of microorganisms is inhibited. Therefore, it is possible to purify river water through an underground aquifer recharge tank without chemical disinfection such as chlorine treatment.

Hereinafter, a water treatment apparatus using a gabangtae intake beam and a gabangtae intake beam and an underground aquifer recharge tank according to an embodiment of the present invention will be described in detail with reference to the drawings.

Referring to FIGS. 1 to 3, the gabion intake beam 100 according to an embodiment of the present invention includes a plurality of unit gabions 110. The gabion intake beam 100 made of a plurality of unit gabions 110 is provided in a shape that crosses the river.

The unit gabion 110 forms a rectangular parallelepiped shape as an embodiment, and the plurality of unit gabions 110 forms a stacked structure in the form of stacking. The gabion intake beam 100 comprising a plurality of unit gabions 110 may be configured in a plurality of stages in a vertical direction, and may be configured in a plurality of rows in a river flow direction. The number of rows in the vertical direction and the number of rows in the river flow direction may be designed to be the same, or the number of rows may be reduced toward the top. For example, all stages can be constructed with the same number of rows, or the first stage is constructed in three rows and the second stage is constructed in two rows. The method of reducing hot water toward the upper end can reduce bed erosion by reducing the drop in the discharged water when the river water is discharged.

The unit gabion 110 is composed of a mesh 111 and a filling material 112 filled in the mesh 111, as shown in FIG. 4A. The net 111 is a frame provided with a net for preventing the filler 112 from being lost while providing a space for the filler 112 to be filled, and may be manufactured in various forms. In an embodiment, the network 111 may be configured as a polygonal body such as a rectangular parallelepiped or a spherical or cylindrical shape. In addition, in order to fill the filling material 112, the upper surface of the mesh 111 may be configured in the form of a cover.

The filling material 112 filled in the net 111 may use natural stone or crushed stone of a certain size. The size and shape of the filling material 112 affects the gaps or voids between the filling materials 112, and the gaps or voids between the filling materials 112 have a close relationship with the water permeation amount of river water and the passing amount of fine soils, It is necessary to determine the size and shape of the filling material 112 in consideration of the amount of permeation of river water and the amount of fine soil passing through.

As the unit gabions 110 filled with natural stone or crushed stone are stacked to form a beam, some of the river water can pass through the stone and stone gap of the unit gabion 110, so that the river water in the gabion drain 100 is not stagnant It will be possible to maintain a continuous flow form. Thus, eutrophication of river water is prevented. Along with this, it is possible to pass fine soil and fine fish in addition to river water through the stone and stone gap of the unit gabion (110). The passage of microsoil prevents deposition in the gabion water intake pipe 100 to suppress dryness, and the passage of microfish may prevent the aquatic ecosystem from being disconnected due to the beams.

In addition, in order to prevent the unit gabion 110 arranged in a row from being separated, a fixing part 140 and a cable for preventing separation are provided. The fixing part 140 is provided on both sides of the river in which the gabion water intake beam 100 is provided, and both ends of the cable 150 for preventing separation are fixed to the fixing part 140, respectively. The separation preventing cable 150 is provided in a form in close contact with the unit gabion 110 arranged in a row to prevent the unit gabion 110 from being separated from the heat.

Along with this, a sheet pile can be constructed for the stability of the gabion intake beam 100 on the ground in the area where the gabion intake beam 100 is installed, and in the case of a soft ground with a large vertical water head difference, the order wall to prevent leakage. May be installed.

On the other hand, the unit gabion 110 constituting a specific row of a specific stage includes a porous carrier 123 instead of the filling material 112. That is, in the case of the unit gabion 110 constituting a specific row of a specific stage, the porous carrier 123 is filled in the network. Hereinafter, the unit dolmantae filled with the porous carrier 123 will be referred to as a'purification unit dolmantae 120' for convenience of description.

The porous carrier 123 is a porous filter material that provides a space for aerobic microorganisms to grow and filters pollutants contained in river water. Aerobic microorganisms grow on the surface and pores of the porous carrier 123 to decompose organic pollutants of river water, and the porous carrier 123 itself filters pollutants of river water. The reason why aerobic microorganisms can grow on the surface and pores of the porous carrier 123 is that turbulence is induced in the pores of the porous carrier 123 by the flow of river water, and the so-called contact between air and water is caused by such turbulence. This is because the aeration effect is triggered. Aerobic microorganisms may grow due to the aeration effect in the purification unit gabion 120, and organic pollutants contained in river water are decomposed by such aerobic microorganisms. Therefore, it can be seen that the purification unit gabion 120 serves as a filtration tank and a biological aeration tank. Here, the porous carrier 123 may be made of pearlite or zeolite.

Meanwhile, a perforated collecting pipe 130 is provided in the purification unit gabion 120. The perforated collecting pipe 130 serves to collect the river water that has undergone filtering and biological decomposition processes by the porous carrier 123 and transfer it to an external water collecting tank (not shown). A plurality of water collecting holes are provided on the surface of the perforated water collecting pipe 130 so as to collect river water. The river water in the gabion water intake pipe 100 passes through the unit gabion 110 and flows into the unit gabion 120 for purification, and is collected into the perforated collection pipe 130 after filtration and biological decomposition by the unit gabion 120 for purification. . It is preferable that the heat of the purification unit gabion 120 in which the perforated collection pipe 130 is disposed for filtration and biological decomposition efficiency and collection efficiency is located at the bottom of the gabion water intake beam 100.

Water stored in an external water collecting tank through the perforated water collecting pipe 130 may be used as a water source for a specific purpose or connected to a separate sewage treatment device to allow an additional water treatment process to be applied. As the filtering process and biological decomposition process for river water are completed by the unit gabion 120 for purification, the treated water discharged through the perforated collecting pipe 130 has a certain degree of water treatment applied, and a separate sewage treatment device Even in conjunction with, it is possible to omit a significant portion of the water treatment process.

The perforated collecting pipe 130 may be provided along the row in which the purification unit gabion 120 is arranged, and the perforated collecting pipe 130 may be installed to be selectively detachable. That is, the perforated collecting pipe 130 may be inserted into the unit gabion for purification 120 or the perforated collecting pipe 130 inserted in the unit gabion for purification 120 may be detached. In this case, as shown in FIG. 4B, in order to selectively attach and detach the perforated collecting pipe 130, the purification unit gabion 120 may be configured as a combination of the upper gabion 121 and the lower gabion 122. . The upper gabion 121 and the lower gabion 122 are combined to form a unit gabion 120 for purification, and when the upper gabion 121 and the lower gabion 122 are combined, a cylindrical type to allow insertion and installation of the perforated collection pipe 130 The space 124 is formed. That is, a semi-cylindrical space (124a) (124b) is provided at each facing portion of the upper gabiontae (121) and the lower gabiontae (122), and a cylindrical space when the upper gabiontae (121) and the lower gabiontae (122) are combined. (124) is completed, it is possible to insert and mount the perforated collecting pipe 130 in the cylindrical space 124. In addition, each of the upper gabion 121 and the lower gabion 122 is filled with a porous carrier 123 as described above.

There is a bar.

Purification of river water using the porous carrier 123 is performed by filtration and biological decomposition by the unit gabionta provided with the porous carrier 123, that is, the purification unit gabion 120 as described above. The purification unit gabion 120 is arranged to form a row in a specific stage in the gabion intake pipe 100, and preferably, a specific heat at the lowermost end of the gabion intake pipe 100 may be configured as a purification unit gabion 120.
