Filtration system for artificial backfilling and its cleaning method

technical field

The present invention relates to a filter system for artificial recharge and a cleaning method for the filter system for manual recharge, in particular to a filter system for manual recharge and a filter for manual recharge. The cleaning method of the system, wherein the filtering system for artificial recharging includes cleaning parts for cleaning the filtering parts for filtering the ground water for artificial recharging.

Background technique

In Jeju Island, since the level of groundwater stored underground before 1980 was already higher than that of seawater, spring water overflowed and flowed from various places along the coastline.

However, not only are current spring outflow sources reduced due to lowering of groundwater levels due to rapid urbanization phenomena and sharp increases in water demand, but further groundwater levels are expected to be further lowered by tectonic movements including surface subsidence and seawater introduction, etc.

The main rock of Jeju Island is porous basalt, and since the soil on the ground is composed of fragile volcanic ash, Jeju Island has a structure in which rainwater sufficiently penetrates into the ground when it rains. Moreover, a part of the land equivalent to 6% of the entire land of Jeju Island is composed of Gotjawal (Jeju language), which is an uplift created by lava from volcanic eruptions that splits into large and small rocks. topography.

Gojawa is a structure with holes formed from the surface down to tens to hundreds of meters below the ground where groundwater is stored, where the holes serve to prevent snow accumulation caused by rising warm air and to divert rainwater when it rains. Access to the ground (air hole).

In particular, Gojawa is a forest area protected as a "World Natural and Cultural Heritage", and it is also a unique landform that can only be seen in Jeju Island in the world.

Since Halla Mountain itself is Jeju Island, the landform of Jeju Island itself is formed as a steep slope from Baengnokdam Crater Lake (Baengnokdam Crater Lake) down to the sea. Bailutan Crater Lake is the crater of Halla Mountain.

Therefore, Jeju Island has a landform structure in which a dam capable of storing a large amount of water cannot be constructed. Also, since the streams in Jeju Island have steep slopes, when there is a lot of rain or during the rainy season, the water submerges for a few hours but immediately enters the sea. Therefore, only a very small amount of water seeps into the ground.

Therefore, the streams in Jeju Island are only submerged when it rains, and usually remain in the form of dry streams.

There have been multifaceted efforts to artificially recharge stormwater discharged into the sea by streams in Jeju Island, but during localized heavy rains not only entire houses, uprooted trees, rocks, mud, and pebbles, etc. were carried away by the water, but floating Leaves and domestic waste (agricultural vinyl, etc.) on the water are all mixed in the rainwater (soil water) and flooded, so there continues to be when the water is artificially recharged without removing foreign objects. The corresponding area immediately becomes a reservoir or The problem of wetlands.

Therefore, as a last resort, Jeju Island is looking for a method to gradually artificially recharge a small amount of water from different places.

Among the different approaches, one approach is to use rainwater collected from building roofs or foundation structures to accomplish artificial recharge.

Experts predict that when Jeju Island fulfills its functions as an autonomous province by 2020, there will be less places where rainwater can be naturally eroded due to construction (roads, buildings) due to population expansion and increased tourists, But groundwater levels will drop dramatically due to the extreme increase in water demand and the onset of water salinization due to rapid land subsidence and seawater ingress.

In addition, global warming is shifting rainfall patterns to extreme droughts and localized storms, along with increased water demand.

In particular, to give an example of damage, the People's Daily reported that by 2010, due to land subsidence phenomena, 50 or more cities in China (including Beijing) were severely piled up , an area 300 times the size of Yeoido has subsided by 116cm, and artificial groundwater recharge facilities, which replenish groundwater with safe water using rainwater collection facilities or wastewater purification facilities, are now considered a solution.

In order to solve the above problems, considering the public welfare of the method of artificial recharge of groundwater suitable for the geological characteristics of the Jeju Island area, the research cost and installation cost of the artificial recharge method are currently being supported in Jeju Island.

Therefore, with the goal of installing a total of 42 artificial recharge wells by December 2003, although 6 sites have been constructed to recharge 400,000m3 of groundwater per year, the problem is that due to the regional characteristics of Jeju Island (steep Slope structure), artificial recharge wells in Jeju Island cannot be installed on the mountainside without pollution, artificial recharge wells must be installed near farmland inevitably, and there is agricultural cultivation in farmland, resulting in groundwater being drawn from farmland, golf courses and livestock The problem of agrochemicals from poultry farms and wastewater pollution from animal farms into artificial recharge wells exists even in the common artificial recharge well (underground storage tank) method currently being promoted in Jeju Island The amount of recharged water is too small and far from sufficient to supply the impending explosive growth in the absence of natural springs due to underlying problems including land subsidence.

Although Jeju Island is exploring artificial recharge in different ways using Gojawa in order to solve the above problems, it still has not solved the need to build water channels and reservoir side walls directly to the distant Gojawa structure in order to use Gojawa and the problem of having to separate rainwater and foreign objects.

In particular, since a large amount of domestic waste, soil, sand, and thousands of trees are suddenly taken away during landslides, etc., and flooded rainwater takes away entire houses during local heavy rains, after being flooded by rainwater, Sometimes the terrain changes. For example, entire villages may disappear in vast quantities of mud, sand, and waste.

In addition, some countries are seeing the extent of damage caused by extreme drought and overexploitation of groundwater resources with brutal consequences around the world, including land subsidence.

Therefore, in the process of solving the above-mentioned problems, the applicant of the present invention has applied for Korean Registered Patent Serial No. 10-0879600 on a structure for separating rainwater and foreign objects for artificially recharging flooded rainwater.

In Korean Registered Patent Serial No. 10-0879600, the applicant has invented a structure for filtering large foreign objects (such as large trees and large rocks) and rainwater from water escaping into the sea next to a stream, as A method of separating rainwater from foreign matter using beams or mesh structures on a catchment member and then storing only rainwater underground. However, there may arise a problem caused by settled leaves or discarded vinyl, which are floating objects floating in the water, that is, a problem that the artificial Gejawa, which becomes a place where water seeps into the ground, is clogged with foreign objects, in order to additionally To solve the above problems, the applicant has filed Korean Patent Application Serial No. 10-1047112.

In Korean Patent Application Serial No. 10-1047112, in order to prevent the artificial Gejawa from being clogged with foreign objects, a filter has been provided to complement the aforementioned invention, which separates waste materials such as leaves and waste vinyl. Domestic waste, domestic waste is 5mm or larger floating objects floating in the water. Thus, the structure described has been able to avoid damage caused by localized torrential rains and to use flood waters as a resource.

＝Supplementary content＝

First, a filter member for filtering large foreign objects contained in rainwater (completely uprooted trees, etc.)

Second, a filter member for filtering floating matter (big branches and domestic waste such as vinyl) contained in rainwater and floating on water

Third, the filter element, which is used to filter mud, sand and pebbles

Fourth, the artificial recharge well (artificial Gezawa)

The above-mentioned supplementary content applied for by the applicant has been registered with difficulty during the examination process. However, in the method used to eco-friendly and artificially recharge thousands of bottles of rainwater per second that escapes into the sea during localized storms when significant damage is caused worldwide, it is necessary to separate the rainwater from the Contains fine-grained soil, etc., but this problem remains unresolved.

Therefore, the applicant aims to solve the problem of the filter being clogged by fine foreign matter such as mud in the filter system.

detailed description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

For reference, in the structure of the present invention to be described below, the same structure as the prior art will refer to the above-mentioned prior art, and its individual detailed description will be omitted.

In this embodiment, the filter member will be referred to as a fourth filter member.

As shown in FIG. 1 to FIG. 21 , the filter system for artificial recharge in this embodiment includes: a fourth filter component 400 for filtering artificially recharged groundwater and a cleaning component for cleaning the fourth filter component 400 .

The filter system for artificial refilling in this embodiment further includes a main filter component 100 located at the front end.

The main filter unit 100 is connected to a river or stream, or is installed on an incline on the ground in lowland flooded areas and reservoirs.

For example, the main filtering part 100 may be installed downstream of the dam to prevent flooding, may be installed upstream of the dam to remove large foreign objects introduced into the reservoir of the dam, and may pre-control the amount of water introduced into the dam to control the water level of the dam .

The main filter part 100 comprises: a first filter part 110, which is used to filter large rocks; The second filter 120b, which is arranged at the lower part of the first filter 120a, to filter sand and pebbles; the third filter part 140, which is used to filter floating objects floating on the water; and artificial The backfilling and draining parts 300a and 300b are used to artificially backfill the water passing through the fourth filter part 400 which will be described below.

The first filter member 110 is used to filter large rocks and the like, eg, 50 cm or more, contained in water introduced from a stream.

The first filtering member 110 for filtering large rocks has a plurality of cylindrical protrusions 111 formed on the ground of the waterway at intervals of about 50 cm. The plurality of protrusions 111 are arranged in a "^" shape such that a central portion thereof faces an upstream direction of a stream.

Foreign matter collection space parts 112 are formed on both sides of the protruding part 111 to collect large rocks of 50 cm or more.

The foreign matter collection space portion 112 is formed to communicate with a water channel.

When the water passes through the water channel through the first filter member 110, large rocks of 50 cm or larger are filtered by being captured by the protrusion 111, and the large rocks etc. that are stuck are naturally formed due to the protrusion 111 that is set as a "^" shape. The ground is introduced into the foreign object collection space part 112. Due to this, the maintenance personnel can easily remove the filtered large rocks, etc., and can prevent damage to other structures arranged downstream, and the rocks less than 50 cm are collected in the main filter unit installed on the main filter part through the protrusion 111 and the discharge hole 124. The stream on the left of 100 joins the waterway at 150.

The second filter part 120 includes a first filter 120a and a second filter 120b, and water passing through the first filter 120a falls onto the second filter 120b.

The first filter 120a is set to have a width close to that of a stream. The first filter 120a is used to send rainwater including sand and small pebbles of 5 cm or less to the second filter 120b, while the first filter 120a is only used to filter large foreign objects including 5 cm or more Large domestic waste items and completely uprooted trees, etc., and have a large volume.

The first filter 120a is disposed on the upper portion of the second filter 120b to be supported more stably.

Guide walls 121 for forming water channels are installed on both sides of the first filter 120a.

The first filter 120a has plate filters 122 disposed between the guide walls 121 at both sides thereof.

A discharge hole with a diameter of approximately 5 cm is formed at the plate filter 122, and water can pass through the discharge hole.

In addition, the discharge holes formed at the plate filter 122 are tapered so as to gradually become larger downward. That is, the discharge hole formed at the lower portion of the plate filter 122 may be formed to have a diameter greater than 5 cm. Therefore, foreign matter, such as pebbles and sand introduced with the water, can pass through the discharge hole without being caught.

The panel filter 122 may be provided in a panel shape, and may be provided as a 15 cm thick concrete slab.

The panel filter 122 may be provided divided into several small pieces, and the divided panel filters 122 are stably supported by the panel support beam 123 .

The plate support beam 123 is formed as a frame to surround the outer edge of the plate filter 122, and has a seating groove for the plate filter 122 to be seated therein, and the seating groove is formed on the upper surface so that the position of the plate filter 122 can be firmly fixed. fixed.

As above, the panel filter 122 can be arranged as several separate blocks, and when the panel filter 122 is damaged, only the damaged part needs to be replaced, thus having the advantage of reducing maintenance and repair costs.

A discharge hole 124 for large foreign objects is formed at a lower portion of the first filter 120a.

The large foreign objects filtered through the first filter 120a are discharged through the discharge hole 124 for large foreign objects.

In addition, a guide wall 125 is formed at the first filter 120a so that the large foreign objects are efficiently moved to the discharge hole 124 for the large foreign objects.

The discharge hole 124 for large foreign objects communicates with the left side of a stream connection waterway 150 described below.

Therefore, the large foreign objects are discharged through the discharge hole 124 for the large foreign objects, and are gathered on the left side of the stream connecting waterway 150, and when the maintenance personnel do not remove the large foreign objects, the large foreign objects flow along with the water. Down. In this manner, the accumulation of large foreign objects within the first filter 120a is effectively prevented. Therefore, manual refilling can be performed continuously.

A water channel in the form of a sump is formed at the second filter 120b, and the water channel is three times wider than the width of the stream.

The second filter 120b has an upper portion formed to be opened so that the muddy water containing sand and pebbles less than 5 cm passing through the first filter 120a immediately falls to the second filter 120b to be introduced into the second filter 120b .

The second filter 120b includes a first partition wall 131 and a second partition wall 132. The first partition wall 131 is installed to be separated from the ground of the waterway. Wall 131 is of low height. The first partition wall 131 and the second partition wall 132 are provided in plural and in pairs to form a plurality of spaces in the second filter 120b. In this embodiment, 6 spaces can be formed.

Most of the sand, pebbles, and muddy water that have passed through the first filter 120a fall to the first space part, and due to the water potential forming a horizontal plane, the muddy water flows sequentially from the first space part to the sixth space part. That is, muddy water mixed with pebbles, sand, and foreign matter of 5 cm or less goes to the sixth space portion sequentially through the first partition wall 131 and the second partition wall 132 in the first space portion, so that the heavy The foreign matter, sand, and pebbles of 5 cm or less are deposited and transported to the first sand and pebble collection part 200.

Since the height of the ground gradually decreases toward the first partition wall 131 , the ground of the second filter 120 b is formed to be inclined so that pebbles and sand sunk on the ground are efficiently collected under the first partition wall 131 .

Sand and pebble outlets 136 are formed at side walls of the second filter 120b to effectively discharge pebbles and sand sunk on the ground, and each sand and pebble outlet 136 is provided corresponding to a position where the first partition wall 131 is installed. A discharge valve 133 is installed at the sand and pebble outlet 136 . A water delivery pipe 137 is connected to each discharge valve 133 through which aggregated pebbles and sand are sent to the first sand and pebble collection part 200 together with some muddy water due to water pressure.

The discharge valve 133 can be used to remotely control the artificial recharge flow rate of the artificial recharge drainage parts 300 a and 300 b of the main filter part 100 and the manual recharge drainage part 300 c of the first sand and pebble collection part 200 .

An outlet 134 through which water is discharged is formed at an upper portion of the second partition wall 132 disposed at the lowermost portion of the second filter 120b, and the outlet 134 has a width approximate to that of a stream.

The outlet 134 serves as a water channel that transfers water that has been filtered by the second filter part 120 (the first filter 120 a , the second filter 120 b ) to the third filter part 140 .

Here, tree debris and floating objects of 50 mm or less floating in the water are included in the muddy water to be conveyed to the third filter part 140 through the second filter part 120 .

In addition, a water gate 135 is installed at the second partition wall 132 disposed at the lowermost portion of the second filter 120 b such that the water gate 135 is disposed at a side of the outlet 134 . The water gate 135 is formed to have a lower height than the outlet 134 so that when the water gate 135 is opened, water is discharged only through the water gate 135 and not through the outlet 134 .

Water gate 135 refers to a flow controller that can be opened and closed.

Moreover, the second water gate 138 is disposed on the second partition wall 132 such that the second water gate 138 is disposed on the other side of the outlet 134 . The second water gate 138 is disposed at the upper portion of the discharge hole 124 for large foreign objects. The second water gate 138 is formed small so as to have a smaller cross-sectional area than the water gate 135 .

Since large-scale foreign objects can accumulate in the stream connection waterway 150 via the discharge hole 124, and when the amount of large-scale foreign objects is so large as in the case where many trees are completely uprooted and collapsed when a landslide or the like occurs, the discharge of foreign objects may If it is not smooth, the second water gate 138 can be opened so that it can play a role in promoting the discharge of foreign objects by causing large foreign objects to flow down due to the force of flowing water.

The stream connection waterway 150 is formed to have a width approximate to that of the second filter 120b, and is located at a lower portion of the second filter 120b. A stream connection channel 150 connects the second filter 120b to the downstream portion of the stream.

When the water gate 135 is opened, the water that has passed through the second filter 120b is introduced to the right side of the stream connecting waterway 150 so that it is discharged to a downstream portion of the stream.

Wastewater from animal husbandry including agrochemicals brought from farmland, golf courses, and livestock farms, etc. may be contained in the water introduced at the initial stage of water diversion from streams, and the amount of soil mixed into rainwater due to landslides, etc. may be Too large and almost impossible to filter through the main filter element 100.

In that case, the water gate 135 may be opened to prevent contaminated water from being introduced into the third filter member 140 via the outlet 134 .

The third filtering part 140 is formed to have a width approximate to that of a stream, and serves to filter floating matter such as leaves of 5mm or more contained in muddy water.

The third filter member 140 includes a first end 140a, a second end 140b and a third end 140c, the first end 140a is arranged at the uppermost part, and the second end 140b is arranged at the lower part of the first end 140a and forms To be lower in height than the first end portion 140a, the third end portion 140c is disposed at a lower portion of the second end portion 140b and formed to be lower in height than the second end portion 140b.

The first end 140 a , the second end 140 b and the third end 140 c include a first filter 141 .

The first filter 141 is provided in a plate shape in which a plurality of through holes serving as drainage holes are formed.

The first filter 141 may be provided divided into a plurality, and may be provided as a stainless steel material having a thickness of about 5 mm.

Each end includes a concrete beam 142 for supporting a first filter 141 .

The concrete beam 142 is formed as a frame to surround the outer edge of the first filter 141, and a seating groove in which the first filter 141 is seated is formed on the upper surface so that the position of the first filter 141 may be firmly fixed.

The floating matter filtered by the first filter 141 stays on the upper part of the first filter 141 without separately washing the floating matter, and the floating matter is pushed toward the stream by the force of flowing water, and gradually accumulates in the stream.

Different from the foregoing, the cleaning pump 620 and the cleaning nozzle of the first filter of the third filtering part can be set to allow water to be sprayed to the upper part of the first filter 141 at regular intervals, so as to clean the first filter 141 Flotsam on the boat, making it down into the stream.

The partition bottom plate 140g is obliquely disposed between the first filter 141 of the third filter part 140 and the artificial backfilling and drainage parts 300a and 300b.

The first partition wall 1411 and the second partition wall 1412 are arranged between the first filter 141 and the partition bottom plate 140g of the first end portion 140a and the second end portion 140b, and the first partition wall 1411 is installed to be fixed to the partition bottom plate 140g. The second partition wall 1412 is disposed at a lower portion of the first partition wall 1411 and has a lower height than the first partition wall 1411 .

The first partition wall 1411 and the second partition wall 1412 may be provided in plural by forming a pair, and four spaces may be formed.

Since a through hole of about 5 mm is formed at the first filter 141 of the third filter member 140, most of the first filter 141 that has passed through the first filter 141 has fine sand, pebbles, etc. The muddy water of the foreign matter falls to the first space part of the third filter part 140, and a water level is formed due to the water potential, and the muddy water flows sequentially from the first space part to the fourth space part. That is, the water in the first space part passes through the first partition wall 1411 and the second partition wall 1412 in the fourth space part sequentially from the first space part, and thus will not be filtered by the second filter of the second filter part 120 yet. The fine sand filtered by 120b, the settled soil and foreign matter are collected and transported to the second soil and floating matter collection unit 500 .

As mentioned above, during the flow of muddy water, heavy fine sand and foreign objects sink to the ground.

The partition floor 140g is formed to be inclined to have a gradually decreasing height toward each first partition wall 1411, so that pebbles, fine sand, settled soil, and foreign objects sunken on the ground are efficiently removed under the first partition wall 1411. gather.

The sand and foreign object outlets are formed at the side walls of the third filter part 140 to effectively discharge the foreign objects sunk on the ground, and each sand and foreign object outlet is provided corresponding to the position where the first partition wall 1411 is installed. A discharge valve 1413 is installed at the outlet of sand and foreign matter. The second water delivery pipe 483 is connected to each discharge valve 1413 so that sediment accumulated due to water pressure is transferred to the second sand and floating matter collection part 500 through the discharge valve 1413 together with some muddy water.

The water passing through the first partition wall 1411 and the second partition wall 1412 collects in the last water collecting space installed on the partition floor 140g of the third end portion 140c, and then the water is discharged to the fourth filtering channel 1410.

The fourth water filtering channel 1410 is installed at the side of the third end portion 140c.

The fourth filtering water channel 1410 for performing the fourth filtering supplies the water at the upper part of the partition bottom plate 140g of the third end portion 140c to the fourth filtering part 400 .

When the first valve 464 is opened by the control part, the water of the first water delivery pipe 468 is supplied so that the piston 466 rises. In this way, the piston 466 that has blocked the piston sleeve 465a rises so that the piston sleeve 465a is opened to deliver water to the return pipe 461 and the branch pipe 465 .

The piston 466 rises due to the hydraulic pressure of the water in the branch pipe 465 so that the first ball is inserted into the ball cage 442 and blocks the outlet 443 .

In addition, the water in the return pipe 464 is sent so that the second ball 462 that has blocked the inlet 444 is lifted due to water pressure.

Therefore, water flows in the opposite direction (bottom-up) within the filter 430 . Thus, foreign matter such as fine soil that has blocked the through hole of the filter 430 is discharged to the upper portion of the filter 430 .

Water flows backward by opening the first valve 464 for a predetermined time.

Second, when the second valve 472 is opened by the control part at the upper part, which is upstream of the filter 430 when the first valve 464 is opened, the water of the second water delivery pipe 471 is sprayed through the water nozzle 473 . That is, the second valve 472 is operated in such a manner that the first valve 464 is operated about 4 to 5 seconds earlier than the operation of the second valve 472 to expand the filter 430 .

The water sprayed from the water nozzle 473 cleans the upper part of the filter 430 . Thus, the foreign matter that has been discharged to the upper part of the filter 430 through the first step is washed away, and is collected into the foreign matter collection passage 453, gathered into the foreign matter collection space 482, and then transported to the second soil and floating Object collection unit 500.

Through the above-described process, foreign objects stuck in the through holes of the filter 430 can be effectively removed.

When cleaning is complete, the first valve 464 and the second valve 472 are closed. When the first valve 464 is closed, the first ball 467 descends due to its gravity to open the outlet 443 and the piston 466 falls to close the return pipe 461 . Also, since the water pressure is no longer applied to the second ball 462, the second ball 462 descends due to its gravity so that the inlet 444 is blocked.

In addition, various methods can be used as a method of causing water to flow (inject) backward to the filter 430 through the first cleaning part 460, and it is also possible to make the second cleaning part 470 spray water to the filter 430 by various methods. .

Therefore, the filter 430 is able to perform the filtering function again.
