Description

The present invention relates to a pollutant purification system having a block-

The present invention relates to a non-point pollution source purification apparatus, and more particularly, to a non-point pollution source purification apparatus having a block-type connection type capable of filtering inflow non-point pollution sources.

In general, various methods of efficiently using natural abruptness to solve water shortage are being researched and developed. However, since such rainwater is exposed to various pollutants in the atmosphere and is discharged downward including the rainwater, it is also impregnated with various contaminants along the river surface, so that the pollutants contained in such rainwater are removed, It is necessary to establish an early stormwater purification facility.

The pollutants include point pollutants and pollutants discharged from limited point pollution sources such as living excellence, industrial wastewater and livestock wastewater, and agricultural products such as agricultural land, pasture land, forest land, construction site, mine, harvesting land, waste disposal site, Emissions zones, such as urban, road and industrial sites, can be divided into nonpoint pollutants emitted from a wide range of nonpoint pollution sources.

The pollutants discharged from the pollution sources are distributed in various forms such as heavy metals, pathogenic microorganisms, organic compounds, radioactive substances, toxic substances and other salts. These pollutants are usually washed in rainwater during rainfall and flow into public waters such as rivers, lakes, lakes, etc., along with rainwater, thereby causing water pollution. In addition to destruction of the ecosystem, It causes a great harm. In the case where no measures are taken for the treatment facilities near nonpoint pollution sources or only various kinds of rocks, oil and heavy metals provided from nonpoint sources are removed, untreated organic matter flows into the rivers and is a main cause of polluting the rivers.

Therefore, it is required to install a preventive facility for treating nonpoint pollution sources. During the development project, non-point pollution plans are designed to minimize the area and period of exposure to rainfall and to minimize the disturbance of the surface topography and slope areas where non-point pollutants are likely to leak. In addition, the backfilling soil for use in the soil and aggregate collection processes stored on site is covered with a cover to prevent exposure to rainfall, and the drainage path is installed to cut off the soil discharged during rainfall and to flow into the nonpoint source facility.

In the case of point pollutants among pollutants, separate purification devices and wastewater treatment facilities are installed in households, factories, and livestock farms to clean the pollutants to a certain extent. However, in the case of nonpoint pollutants, However, most of them remain on the surface of the earth, and rain water is introduced into public water bodies such as rivers, inner lakes, lakes, and water sources, and ground water.

Particularly, in the case of a manhole which is installed at the edge of the road and discharges the rainwater, the non-point pollutants and the pollutants on the road surface are piled up and flowed in the case of rainwater. In case of not treating such non-point pollutants, There is a problem of serious contamination.

Conventional technologies for treating such non-point pollution sources include natural facilities such as storage facilities, artificial wetlands, infiltration facilities, vegetation type facilities, and filtration type facilities, vortex type facilities and screen type facilities.

In the case of a reservoir, heavy rainfall in the summer necessitates large-scale land or equipment, and when the untreated water is maintained, insects such as flies or mosquitoes are generated, thereby causing hygienic problems. In case of infiltration type, soil or suspended matter generated in the construction is introduced and clogging of pores occurs. Vegetation type requires land of a certain size or larger and conditions for maintaining vegetation are required. However, when four seasons are distinct, The pollution is not constant.

A variety of techniques are known, such as an initial superior purification treatment apparatus of Korean Patent No. 0779513, a non-point pollution purification apparatus of early effluent of No. 561092, but most of them are limited to physical treatment methods such as precipitation and filtration. There is a problem that it can not be removed. Particularly, there is a problem that the filter, the filtration device or the sedimentation paper are contaminated before the non-point pollution source is removed by the impregnated influent.

The present invention can remove nonpoint pollution sources or impurities from treated water such as stormwater, sewage, and wastewater, and one embodiment thereof is shown in FIG. 1 to FIG.

Referring to FIG. 1, a non-point pollution source purification apparatus 10 having a block-type coupling structure according to the present invention is installed at drainage of a road edge, a sewage pipe, a waste water inflow pipe, The inflow water can be simultaneously treated through the upper opening.

The nonpoint source pollution purification apparatus 10 includes a main body portion 20 having an inner space portion 21 with an open upper portion. An inlet port 22 through which the process water flows is formed at one side of the main body section 20 and an outlet port 23 through which the non-point source and the contaminants are removed and purified water is discharged is formed in the main body section 20 corresponding to the inlet port 22 do.

A first unit processing unit 30 for removing contaminants and non-point pollution sources from the water introduced through the inlet 22 into the internal space of the internal space 21 of the main body 20, A first unit processing unit 30 and a stacking unit (located below the first unit processing unit) to deposit and store a non-point source, soil, etc. removed from the first unit processing unit 30, And a second unit processing unit (50) for performing secondary processing on the treated water subjected to the primary treatment by the primary treatment unit (30).

Hereinafter, the non-point pollution source purifying apparatus according to the present invention constructed as described above will be described in detail as follows.

The main body part 20 may be formed in various forms such as a hexahedron or a polygonal circular shape and may be formed in various forms according to the installation place. On the side where the outlet 23 is formed, And a lower side of the outlet 23 may have a substantially same height as the bottom surface of the main body 20. [

A cover 26 for blocking the opening of the internal space 21 is provided on the upper side of the main body 20. The cover 26 may be formed of a grill and is formed on the upper side of the cover 26 It is preferable that the opening ratio of the through-hole 26a is relatively high on the side corresponding to the first processing space which will be described later. This is intended to allow the contaminated water flowing into the ground to flow smoothly into the first treatment space. Here, no through hole is formed in the cover 26 on the side corresponding to the second processing space described later.

The first unit processing unit 30 is inserted into the internal space 21 of the main body unit 20 so that the first unit body 31 opened at the upper part of the main body unit 20 flows in the process water flowing from the inlet port 22 A first processing space portion 33 is formed which is partitioned by the first bank 32 so as to be temporarily stored. The first partition 32 is provided with a first filter unit 34 for primarily filtering contaminants piled up by the treated water or non-point contamination treatment sources. A first overflow hole (35) is formed in the upper first partition (32) where the first filter part (34) is installed, when the first filter part (34) can not process water. The first overflow hole 35 may be used as a handle for separating the first unit processing unit 30 from the main body 20.

The first filter unit 34 may be a wood chip, a porous adsorbent, a bio-filter, or the like, which is contained in the mesh net. As the biofilter, it is preferable to use a porous adsorbent having many internal voids. The porous adsorbent filters the suspended particles by physically capturing the fine particles between the voids or adsorbing them on the surface or pores, . When the internal filtration is performed, the filtration takes place from the surface layer to the inside of the adsorbent, so that the filtration efficiency is good and the period of use is prolonged. Since the wood chip has a large specific surface area, the removal efficiency of particulate pollutants and dissolved pollutants can be expected to be increased in order to adsorb and filter fine soil particles and heavy metals. There is an advantage.

The first filter unit 34 is provided at an outer side lower side of the first partition 32 of the first unit body 31, that is, at a lower side of the first filter unit 34, A second filter unit 36 for filtering the second filter unit 36 is provided. The second filter unit 36 separates the remaining internal space of the first unit body 31 except for the first processing space upward and downward. 6, the upper surface of the second filter unit 36 is formed with a plurality of parallel protrusions 36b aligned in a direction perpendicular to the oblique direction, and a filter hole 36a is formed between the partition protrusions 36b. Are formed.

A plurality of filter holes 36a are formed between the partitioning projections 36b. The filter hole 36a can activate the precipitation of fine contaminants while the process water moves along the second filter portion 36. [ The filter hole 36a of the second filter unit 36 may be formed as small as possible, and a plurality of mesh filters or a ceramic filter may be installed in the filter hole. The second filter unit 36 may be formed of a ceramic filter having surface protrusions formed on the surface thereof so as to filter fine contaminants. The second filter unit 36 may be provided at its end with a cylindrical body 37 that can overflow into a second processing space 55, which will be described later.

The second filter unit 36 may be formed by stacking filters in multiple stages and may be configured to allow water to flow downward through the second filter unit 36.

The second unit processing unit 50 is stacked such that a part of the second unit processing unit 50 is inserted into the main body unit 20 and a part of the second unit processing unit 50 is located below the second filter unit 36, (51) may store the water passing through the second filter unit (36), and a second partition wall (52) for partitioning the pollutant storage unit (53) and the second processing space (55) 54 are installed. A third filter unit 57 is provided in the second partition 54 to remove water from the pollutant storage unit 53 to form a moving path to the second processing space 55, . A second overflow hole (58) is formed on the upper side of the second partition (54) where the third filter part (57) is formed. The second over-pull hole 58 may be used as a handle for separating the second unit processing unit 50 from the main body 20. As shown in FIG. 5, the third filter unit 57 removes the remaining non-spot pollution sources included in the treated water filtered by the second filter unit 34, And a body portion 57b. The lower surface of the filter case 57a provided on the second partition wall is preferably formed with a cut-out portion 57c cut in the longitudinal direction so that water can be smoothly drained from the treated water. The filter body portion 57b may be a mesh filter, a ceramic filter, a filter using sintered metal, or the like.

The first unit processing unit 30 and the second unit processing unit 50 may further include a position setting unit 38 for setting a position in the stacking. The position setting unit 38 may have a coupling protrusion 38a on the lower surface of the first unit processing unit 30 to be coupled with the upper end of the second partition wall 54 of the second unit processing unit 50 . However, it is not limited thereto.

The operation of the non-point pollution source treatment apparatus according to the present invention constructed as described above will be described below.

The non-point pollution source water purification device according to the present invention is installed in a pipeline in a region where a non-point pollution source such as a pipeline or a sewer pipe is installed at the edge of a road, And the like.

This process will be described in more detail. When the process water flows into the inlet 22 through the pipeline, the process water flows into the first process space 33, and the process water flowing into the first process space 33 The treated water flowing through the inlet 22 is filtered by the first filter 34 and the second filter 34 is filtered by the first filter 34. In other words, The flocculent material among the floating contaminants contained in the treated water floats up to the upper portion of the treated water stored in the first treatment space 33 and is separated. As the treated water in the first treatment space 33 passes through the first filter unit 34, the non-flooded contaminants and relatively large non-spot pollution sources, tire powder, oil, asphalt, Or attached to the filter and removed. The treated water that has passed through the first filter unit 34 passes through the second filter unit 36. The second filter unit 36 is installed at an inclined angle and the irregularities are formed on the surface, , And the like. In this process, when the inflow amount is larger than the processing amount of the processing water filtered by the first filter unit 34, a part of the untreated processing water flows through the first overflow hole 35 into the second filter unit 36 . The second filter unit 36 is inclined so that the foreign matter piled in the treated water passing through the second filter unit 36 can be separated by the difference in the specific gravity of the pollutant. On the upper side of the second filter unit 36, The pollutant having a relatively low specific gravity can be filtered, and the second filter portion 36 can be prevented from being easily clogged.

The treated water that has passed through the second filter unit 36 is moved to the pollutant storage unit 53 side and temporarily stored therein. The pollutant contained in the treated water that is not filtered by the second filter unit 57 Precipitated and removed.

The treated water stored in the pollutant storage unit 53 flows into the second storage space 55 after passing through the third filter unit 57 installed in the second partition 54. The contaminants are finally settled in the second storage space 55 (settled as the flow rate relatively slows) and then discharged through the outlet 23 formed in the main body 20.

In addition, when contaminated water is not introduced from the inlet 22, the lower portion of the outlet 23 is formed at substantially the same height as the bottom, so that the treatment water can be prevented from remaining in the body, It is possible to prevent the insect pests from being inhabited by the remaining treated water and to prevent the treated water and the impurities from being corrupted and generating odor.

Meanwhile, the non-point pollution source apparatus according to the present invention may be used to clean or replace the first, second, and third filter units of the first and second unit processing units 30 and 50, or to remove contamination or non- The first unit processing unit is separated from the main body portion 20 to clean the first and second filter portions 32 and 36 and remove the contaminants stored in the first processing space 33. [ The second unit processing unit 50 is separated to remove pollutants stored in the cleaning and pollutant storage unit 53 and the second processing space 55 of the third filter unit 57, .

The inner space of the main body 20 can be cleaned by spraying washing water. In this case, the washing water is discharged through the outlet 23 of the main body 20.

As described above, the non-point pollution source purification apparatus can purify non-point pollution sources through precipitation with a multi-stage filter, thereby improving the purification efficiency and facilitating maintenance.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
