The present invention relates to a stream purification system and method for improving the water quality of polluted rivers and for gradually recovering the natural ecosystem.

In modern times, due to industrial development and population growth, pollutants such as wastewater or domestic sewage, which pollute rivers, are released without any filtration, contaminating water quality. As a result, various living organisms disappeared, and the natural ecosystem is destroyed, and by using it as agricultural water, various plants grown for human food are also greatly polluted, causing a great disaster for humans. In addition, the damage of the natural ecosystem makes the natural purification of the water itself impossible, so that the polluted river is continuously deteriorating, and the problem becomes more serious. Therefore, the wastewater is sufficiently purified through a separate sewage treatment facility prior to discharge of the wastewater into the river. However, this process is mainly focused on the removal of suspended solids and organic matters, and is somewhat insufficient in the management and removal of nutrients such as nitrogen or phosphorus, which are the decisive factors of eutrophication. On the other hand, the increase in concentration due to the continuous discharge of nutrients deepens the eutrophication of public waters such as rivers, causing secondary pollution such as green algae. However, the removal of the nutrients required a physicochemical advanced treatment facility, and a huge financial burden was required to install and maintain it.

Recently, river purification treatment techniques such as utilizing aquatic plants or using activated carbon have been attempted to solve such problems. Here, the river purification technique using activated carbon, which is known to have a high specific surface area and has a self-cleaning ability, will be described. Let's do it.

Efforts to purify streams using activated carbon have been conducted since the 1930s, and such activated carbon is widely known to have excellent adsorption capacity of nutrients in water treatment. According to Utility Model Registration No. 293992, which is disclosed as a non-exhaustive example of a technique utilizing this, a sewage pipe through which river water flows is formed, and a pack containing activated carbon is placed inside the sewage pipe, and the floating material covers the surface of the pack. There is configured to include an inlet network to cover the inlet of the sewer pipe and the outlet network to cover the outlet of the sewer pipe to prevent the loss of the pack containing the activated carbon to prevent.

However, in the use of the above-described technology, first, a structure for fixing the installation of the sewer pipe is required, and such a structure is formed on the bottom of the river and the concrete on the bottom of the stream in a state where the flow of the river is partially blocked over a certain section. It requires a process such as grounding mortar, and there is a lot of cost problems in forming a lot of labor and its facilities. In addition, the above-described activated carbon requires periodic replacement, in which the worker separates the inlet or outlet network from each sewer pipe which is a fixed structure in the stream and replaces the activated carbon pack located therein from the separation. There is a hassle to do. In addition, the above-mentioned facility acts as a factor of inhibiting the flow of the river water when the flow rate of the river water is low due to drought, etc., and it is difficult to install the facility having a deep depth of the river, and the replacement of the activated carbon pack is more difficult. Have a problem.

The river purification system which concerns on this invention is provided so that 1st support part 10a, 10b may mutually face each other in both banks D of a stream, as shown in FIG. In addition, at least one or more second support portions 12 are fixedly installed at random intervals on the bottom of the river between the first support portions 10a and 10b. And between the first support portion (10a, 10b) including the second support portion 12 to connect a rope 14 of a predetermined length in the shape of crossing the width direction of the river, wherein the rope 14 is the first, second It is placed in a state of being supported by the supports 10a, 10b, 12.

Here, the rope 14 described above is hypothesized to form at least two or more parallel rows with respect to the first and second support portions 10a, 10b, and 12. In this case, each rope 14 may be fixed to the first and second supports 10a, 10b, and 12, but is preferably supported by the first and second supports 10a, 10b, and 12 according to the hypothesis. It is more effective to install in the longitudinal direction. In addition, as described above, each rope 14 capable of flowing in the longitudinal direction according to the temporary installation between the first supporting portions 10a and 10b may be formed in a ring shape so as to continuously rotate and flow in the section.

On the other hand, as shown in Figs. 1 to 3, the rope 14 provided with the support of the first and second supporting parts 10a, 10b, and 12 is provided with a predetermined area along the longitudinal direction of the rope 14. The plurality of nets 16 to be partitioned are installed at regular intervals using the connector 16b. As shown in FIG. 2, the mesh 16 has a sidewall portion having a mesh shape, and as a result, the river water can be penetrated through the sidewall to secure the fluidity of the river water. In addition, the net body 16 forms an opening and closing structure having a locking portion 16a to mount the activated carbon pack P containing a plurality of activated carbons therein. In addition, the above-described activated carbon pack P accommodates a plurality of activated carbons having a size larger than the mesh so as to be difficult to detach from the mesh-shaped mesh 16 before the opening thereof is made, and prevents the activated carbon of the predetermined size from being separated. At the same time, it is possible to penetrate river water.

Meanwhile, the rope 14 described above is hypothesized so that at least two or more of the first and second support parts 10a, 10b, and 12 are arranged in parallel to each other, and the mesh 16 described above is adjacent to each other. 14) Connect them at regular intervals to receive their support. In addition, these meshes 16 may be configured to support each other complementarily to maintain a gap between the rope 14 is supported. In addition, the above-described locking part 16a is to enable mounting and withdrawal of at least one activated carbon pack P with respect to the inside of the net body 16.

In the above-described configuration, one embodiment of the first and second support portions 10a, 10b, 12 for supporting the flow of the rope 14 in more detail, as shown in Figs. It has a support shaft 12a which is erected in the shape of a pile from the bottom part of the dike D or the river which is formed. The support shaft 12a is provided with a curved bracket 12b having a section for the construction of the rope 14 therebetween, and between the support shaft 12a and the bent portion of the bracket 12b. By applying pressure in correspondence with (14), there is no flow to the side in the longitudinal direction and at the same time, the pulley 12c is fixed to the rotating shaft 12d to allow rotation from contact with respect to the flow direction of the rope 14. Doing. In addition, the above-described configuration of the bracket 12b, the rotating shaft 12d and the pulley 12c constitute an up and down direction with respect to the support shaft 12a, and such an up and down arrangement is such that the rope 14 has a ring shape. To support the flow section correspondingly. In response to the rope 14 being constructed in two or more rows, the support 14a may be further provided between the support shafts 12a corresponding to both sides to support the gaps. The pulley 12c provided on the support shaft 12a described above is illustrated in FIG. 2 as being pressed against both sides with the rope 14 interposed therebetween to prevent its flow in the longitudinal side direction. The force pushing against the side of 14) causes the rope 14 to be elastically supported in the longitudinal direction between each of the first and second supporting portions 10a, 10b, and 12, on either side of the pulley 12c. It may be made of a configuration to install. To this end, as shown in FIG. 1, it is hypothesized that the first support portions 10a and 10b of any one of the first support portions 10a and 10b can be moved in the longitudinal direction of the rope 14. It may be made to provide a tensile force against the rope (14). The gap between the pulleys 12c pressurized from both sides with the rope 14 interposed therebetween prevents the detachment of the rope 14 and at the same time the connection between the sections between the ropes 14 parallel to each other. It is for making the connection site | part of the net body 16 made to pass through possible.

In addition to this configuration, the ropes 14, which are held at regular intervals in the section between the second supports 12 lying on the bottom of the stream, alternately with respect to the second supports 12, as shown in FIG. By receiving the support, it can be laid in a twisted shape while maintaining a constant distance from each other in the longitudinal direction. This is to allow the mesh 16 opposite the stream flow to be rotated from the progression of the rope 14 and thus the surface phase of the activated carbon pack P facing the stream water and the activated carbon contained therein. This is to increase the efficiency by having a surface selectivity for the removal of suspended solids and adsorption of eutrophication.

Meanwhile, power is transmitted to one side of the above-described first supporting parts 10a and 10b to allow the rope 14 to flow in the longitudinal direction, and the activated carbon pack P is replaced with respect to the mesh 16 positioned therefrom. It may be further provided with a replacement portion (18a, 18b), the replacement portion (18a, 18b) is a rope 14 to rotate the rope 14 of the winch or ring shape winding the rope 14 Any one of the pulleys 12c or rollers (not shown) that are connected to the roller may be configured to further include driving means such as a motor for providing rotational power.

In addition, the activated carbon used by this invention uses bamboo activated carbon. Such bamboo activated carbon has been developed as a macropore suitable for water purification as the size of the pores, which is an important factor for the adsorption of nutrients, compared to other activated carbon, as shown in the drawing substitute photograph shown in Table 1 and FIG. 4 below. It can be seen.

<Table 1> Comparison of bamboo activated carbon and coconut shell activated carbon

As shown in the comparison of Table 1 above, bamboo activated carbon is not only large in size compared to ordinary coconut shell activated carbon, but also has a specific surface area in the range of 450 to 485 m 2 / g and a wider range of selective at about 474 m 2 / g. It can be seen that it has adsorption property and pore volume is also in the range of 0.250 ~ 0.280 dl / g and has the highest pore distribution compared to other activated carbon in the range of about 0.269 dl / g.

In addition, as shown in Table 2 below, which compares the electrical conductivity of bamboo activated carbon with other activated carbon, bamboo activated carbon has a higher electrical conductivity compared to other activated carbons, and thus cations dissociated in river water, that is, organic pollution. High adsorption rates for materials and heavy metal ions can be expected.

TABLE 2

In addition, looking at Table 3 below, which shows the components of bamboo activated carbon after incineration, it can be seen that arsenic (As) and lead (Pb), which are heavy metal pollutants, are not detected and are stable.

TABLE 3

Although activated carbon is mostly dependent on imports, bamboo, which is a raw material of activated carbon, has a wide distribution and a large amount of production from the west coast of Taean Peninsula and Goseong in Gangwon-do, South Korea, with reference to Table 4, It is a useful material that can be made smoothly.

TABLE 4

As described in the above description, the first and second supports 10a, 10b, and 12 are fixedly installed in the local range with respect to both banks and the river floor therebetween, and the first and second supports 10a, 10b, and 12 are fixed. The rope 14 is hypothesized across the width direction of the river. At this time, on the rope 14 described above, the installation of the facility is achieved by connecting the net 16 to which the activated carbon pack P is mounted.

From such a configuration, a replacement operation is carried out to mount the activated carbon pack (P) or to take out the activated carbon pack (P) previously mounted on the net 16 located at one side of the embankment (D). Thereafter, the net body 16 equipped with the new activated carbon pack P is immersed in the opposite river water and the rope 14 is moved to move in the opposite direction. After a certain time has elapsed, the moving position of the rope 14 is adjusted to move the net body 16 for a predetermined period, wherein the moving section is at least once a period during which the adsorption capacity of the activated carbon pack P is lowered. The above-described divided and activated carbon packs P consist of repeatedly performing a series of processes of replacing the new activated carbon packs P at the positions of the replacement parts 18a and 18b on the opposite side or by rotation.

Here, the activated carbon pack (P) may be desirable to be made at the embankment position, but if the width of the river is wider than the width of the relay unit using at least one or more concrete structures, etc. in the interval between them (not shown) It is also possible to replace the activated carbon pack (P) having a reduced adsorption capacity through this relay (not shown).

Therefore, according to the present invention, the installation is easily performed by a series of processes for fixing the first and second supports to the bottom at random intervals with respect to the width direction of the river and connecting the ropes to these first and second supports. At the same time, work time and cost are reduced, and moving the rope makes it easy for the operator to replace activated carbon through the mesh at the embankment position, and use bamboo activated carbon with more specific surface area and smooth supply of materials than other activated carbon. By doing so, there is an effect of improving the purification capacity and reducing the cost.

Although the present invention has been described in detail only with respect to specific embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the scope of the technical idea of the present invention, and such modifications or changes belong to the claims of the present invention. something to do.
