According to the UN World Water Resources Development Report, by 2025, about 2.7 billion people, or 40% of the world's population, will face water shortage, and about 20% of countries around the world will experience severe water shortages. This is because, while supply is limited, demand continues to increase due to population growth and higher income levels.

Meanwhile, the tap water we drink is produced after purification using various water systems such as rivers, dams and lakes as raw water. Specifically, the extracted raw water undergoes a coagulation step, a sedimentation step, a sand filtration step, an activated carbon filtration step, an ozone oxidation step, a separation membrane filtration step, and the like in a water purification plant to remove various suspended and dissolved substances.

In order to prevent contamination by microorganisms that have not been removed and microorganisms that may occur during the water supply process, it is a general water treatment process to supply water to each household after the sterilization process.

However, in the case of islands or mountainous areas, there are areas where a proper water purification plant is not installed, and even if a simple water purification plant is installed, it is often not possible to produce and supply safe drinking water due to inexperience in operation.

2 is a perspective view viewed from one side of the coagulated precipitation unit of the present invention.

As shown in FIG. 3 , the flocculation and sedimentation unit 200 includes an adsorption and flocculation reaction unit 220 and a solid-liquid separation unit 230 in one body unit 210 . That is, as seen in FIG. 2 , a separation partition 216 is provided along the longitudinal direction of the coagulated sedimentation body 210, and on the right side, after raw water is introduced, various trace contaminants such as odor-causing substances are adsorbed by the activated carbon. The adsorption and flocculation reaction unit 220 is located in which the activated carbon and various contaminants are aggregated with each other by the coagulant injected, and the solid-liquid separation unit 230 is located on the left side for solid-liquid separation after the adsorption and flocculation raw water is introduced. .

Conventionally, it is common to separately provide a reaction tank for adsorption of activated carbon and a coagulation/precipitation reaction tank for solid-liquid separation. However, the flocculation precipitation unit 200 of the present invention is provided with an adsorption and flocculation reaction unit 220 on one side, and a solid-liquid separation unit 230 on the other side adjacent to one side of the flocculation precipitation body 210 inside. There is an advantage in that it is easy to secure a space, and the manufacturing cost can be reduced.

The agglomerated precipitation body 210 has a rectangular or square cross-section as viewed from above, and a predetermined height, and is empty inside. In addition, a raw water inlet 211 into which raw water to be purified with drinking water such as river water or lake water is introduced is provided on one side, and a supernatant water outlet 212 through which the final treated water is discharged is formed near the same side.

In addition, the bottom surface of the flocculated sedimentation body 210 collects hopper-shaped sludge whose cross-sectional area gradually narrows downward so as to easily collect sedimentation or agglomerated sludge generated in the activated carbon adsorption process, flocculation process, and settling process, which will be described later. A portion 213 is provided. Here, the sludge collecting unit 213 may individually collect sludge generated in each of the activated carbon adsorption process, the coagulation process, and the settling process. In addition, the sludge collection unit 213 is provided with a sludge discharge pipe 214 for discharging the collected sludge to a predetermined concentration or more or for discharging at regular time intervals, and the sludge discharge pipe 214 opens and closes the discharge of sludge. A sludge discharge valve 215 is mounted.

3 is a cross-sectional view taken along line A-A' of FIG. 2 . With reference to FIGS. 2 and 3 , the adsorption and flocculation reaction unit provided in the space on one side of the coagulation precipitation body 210 will be described in detail.

As described above, the adsorption and flocculation reaction unit 220 formed by the separation barrier rib 216 provided along the longitudinal direction of the coagulation precipitation body 210 includes at least one first baffle plate 222 and at least one agent. 2 includes a baffle plate 224 .

In more detail, one or more, more preferably two or more, and most preferably three or more first baffle plates 222 are formed so that the raw water introduced into the raw water inlet 211 first contacts the activated carbon. An activated carbon injection pipe 221 for injecting activated carbon is located near the raw water inlet 211 . At this time, the first baffle plate 222 is preferably formed in a zigzag when viewed from above, which is to induce natural agitation and mixing with the activated carbon by the water flow of the moving raw water.

Here, the activated carbon is preferably powdered activated carbon, more preferably 1,250 mesh or less, and may be injected in a slush state mixed with water, but is not limited thereto.

A coagulant injection pipe 223 , a second baffle plate 224 , and a stirrer 225 are provided behind the first baffle plate 222 . In detail, a known coagulant, mainly aluminum or iron, is injected into the rear of the first baffle plate 222 in a predetermined concentration range through the coagulant injection pipe 223 . Then, a stirrer 225 is positioned in the space partitioned by one or more, more preferably, two or more second baffle plates 224 to stir the coagulant and raw water.

At this time, the stirrer 225 is preferably two, one is for rapid stirring and the other is for slow stirring. Since the rapid stirring and slow stirring as described above correspond to techniques commonly employed in the field of water treatment using a coagulant, a detailed description thereof will be omitted. Of course, one stirrer 225 can be used for rapid stirring, because the perforated plate 231 to be described later can serve as a slow stirring.

On the other hand, unlike the first baffle plate 222 , the second baffle plate 224 is in contact with the bottom and side surfaces of the main body part 210 , and the separation partition wall 216 , except for the upper periphery. Therefore, the raw water passing through the first baffle plate 222 moves while overflowing the upper periphery of the second baffle plate 224 , and for this purpose, the height of the second baffle plate 224 is lower than that of the first baffle plate 222 . .

In the adsorption and flocculation reaction unit 220 as described above, various contaminants such as odor-causing substances contained in raw water are adsorbed by contact with powdered activated carbon, and then suspended contaminants and dissolved contaminants by injection of a coagulant. Some are granulated and settling to the bottom of the coagulation sedimentation body 210 , and the precipitated contaminants are collected in the sludge collection unit 213 .

4 is a cross-sectional view taken along line B-B' of FIG. 2 . The solid-liquid separation unit 230 provided in the space on one side of the coagulated sedimentation body 210 will be described in detail with reference to FIGS. 2 and 4 together.

In the above-described adsorption and agglomeration reaction unit 220, a part of various contaminants may be precipitated and removed by injecting powdered activated carbon and a coagulant. However, it still contains contaminants and requires additional purification steps. In particular, when the coagulant is injected and stirred, the particles become large and easy to settle, but some particles are still small and do not settle easily. In the solid-liquid separator 230, as described above, the contaminants having small particles are made larger and settling, and the particles are no longer large and thus perform a function of separating and removing materials that are difficult to settle.

The solid-liquid separator 230 includes one or more perforated plates 231 having a plurality of through holes 231-1, a guide plate 232, and two or more inclined plates 233 inclined at a predetermined angle.

Specifically, in the space portion of the flocculation and sedimentation body 210 on the opposite side of the adsorption and flocculation reaction unit 220 with the separation barrier 216 interposed therebetween, a plurality of through holes 231-1 are drilled in the horizontal and vertical directions on the surface. The thin perforated plate 231 is vertically arranged, which induces the particles of contaminants to become large. That is, the raw water passing through the adsorption and flocculation reaction unit 220 has a faster flow rate when passing through the through hole 231-1 of the perforated plate 231, whereas the flow rate decreases after passing through the through hole 231-1. Since it is lowered, the stirring effect of the raw water is induced, and thus, the particle diameter can be large enough to allow contaminants with small particles to settle while passing through the perforated plate 231 .

On the other hand, the separation partition wall 216 near the perforated plate 231 that is farthest from the outlet 212 is installed slightly lower so that the effluent from the adsorption and coagulation reaction unit 220 can flow into the solid-liquid separation unit 230, or It is preferable that a flow path (not shown) is opened in the separation partition wall 216 .

A guide plate 232 in which the lower periphery is bent at a predetermined angle in the direction of the outlet 212 is positioned at the rear of the perforated plate 231 so that the raw water that has passed through the perforated plate 231 can move to the vicinity of the bottom of the main body 210 . This is to induce the flow of raw water so that the raw water can pass through the inclined plate 233 to be described later in an upward flow.

As described above, while passing through the one or more perforated plate 231, the size of the contaminant particles is sufficiently large and settles to the bottom of the main body 210, but there are also contaminants whose particles do not grow anymore.

The swash plate 233 provided at the rear of the guide plate 232 is to guide raw water in an upward flow to cause collisions between the particles and the swash plate 233 to remove particles that are difficult to settle. Specifically, the swash plate 233 is composed of two or more inclined at a predetermined angle, more preferably 50° to 70° from the water surface. In addition, the two or more swash plates 233 are preferably spaced apart from each other by a predetermined interval, more preferably 4 cm to 6 cm.

Here, if the angle of the swash plate 233 is less than 50 ° or the separation distance is less than 4 cm, the processing capacity of raw water is too small, and on the contrary, if the angle of the swash plate 233 exceeds 70 ° or the separation distance exceeds 6 cm, the particles and Since the swash plate 233 cannot sufficiently contact each other and the removal efficiency of particles is low, the angle and the separation distance of the swash plate 233 are preferably within the above ranges.

The concentration of algae and various contaminants is remarkably low in the water that has passed through the swash plate 233 in an upward flow as described above, and then after passing through the overflow ware 234 located above the swash plate 233, the final treated water is discharged from the outlet. (212).

Subsequently, the first filtering unit 300 will be described. 5 is a view for explaining a filtration process of supernatant water as a filter unit of the present invention, FIG. 6 is an enlarged perspective view of the first swash plate and the second swash plate, and FIG. 7 is a view for explaining the cleaning process of the filter medium layer.

The first filtration unit 300 according to the present invention includes a filtration unit body 310 , a first swash plate 311 , a second swash plate 312 , and a washing unit 313 positioned inside the filtration unit body 310 . ), a filter medium layer 314 , a water collecting space 350 , a pressing member 316 , and a through pipe 317 , and the like.

The filter body 310 has a predetermined shape such as a circular or polygonal cross section, and a first swash plate 311, a second swash plate 312, a washing unit 313, a filter medium layer 314, and a water collecting space ( 315), the pressure member 316 and the through pipe 317, etc. have a predetermined height with an empty interior. Here, the material of the filter body 310 is not particularly limited, but is preferably made of metal having corrosion resistance and durability as an example.

A first swash plate 311 is provided at a predetermined height inside the main body 310 of the filtering device, and the first swash plate 311 serves as a passage through which supernatant water or backwash wastewater, which is raw water for filtration, moves.

Specifically, as shown in FIG. 6( a ), a first main pipe connection hole 311-1 is formed in the central portion of the first swash plate 311 , and a first main pipe connection hole 311-1 is formed. One or more through-pipe first connection holes 311 - 2 are provided on the outside. Here, a first main pipe line 318 for supplying supernatant water or discharging the pollutant particle layer 314-1 accumulated on the filter medium layer 314 is connected to the first main pipe connection hole 311-1. In addition, the through-pipe 317 is mounted in one or more through-pipe first connection holes 311 - 2 .

When viewed from the front, the first swash plate 311 preferably has a narrow upper portion and a wider lower portion of the first swash plate 311 . This is to easily collect backwash wastewater generated during backwashing of the filter medium layer 314 .

A second swash plate 312 for uniformly supplying supernatant water to the surface of the filter medium layer 314 is provided under the first swash plate 311 . As shown in FIG. 6(b) , the second swash plate 312 has a lower-down light structure similar to that of the first swash plate 311 , and one or more through-holes and second connection holes 312 to which the through-pipe 317 is mounted. -2) and a plurality of water supply holes 312-1 are formed.

In particular, in the plurality of water supply holes 312-1, the cross-sectional area of the water supply hole 312-1 formed in the center, that is, the upper portion of which the cross-sectional area is relatively narrow, is small, and the cross-sectional area of the water supply hole 312-1 toward the lower part, which is the outer part, is small. It is preferable that this is formed to gradually increase, it is more preferable that a plurality of guide walls 312-3 are provided on the upper surface, and the pressure sensor 312-4 is most preferably provided on the lower surface.

In the case of a filtration process using a filter medium, particulate matter is mainly removed from the surface of the filter medium, so it is very important to uniformly supply supernatant water to the surface of the filter medium in order to extend the filtration time or improve the filtration efficiency of particulate matter. In the present invention, the second swash plate 312 is provided with a plurality of water supply holes 312-1 that have the same structure as described above and have a cross-sectional area increasing from the center to the outer shell, and are supplied to the filter medium layer 314 . It is possible to supply supernatant water, which is raw water for filtration, very uniformly. That is, only a portion of the supernatant water supplied to the vicinity of the center of the second swash plate 312 passes through the water supply hole 312-1 with a relatively small cross-sectional area, and the rest flows along the swash plate 312 and passes through the water supply hole 312-1. Since it passes through, there is an advantage that all surfaces of the filter medium layer 314 can be utilized.

A filter medium layer 314 is filled under the second swash plate 312 . The filter medium layer 314 is for removing some of the coarse particles and fine particles contained in the supernatant, and may be filled with a filter medium having a smaller particle diameter as it goes down. For example, the filter medium may be at least one of gravel, sand, anthracite, and activated carbon, but is not limited thereto.

A water collecting space 315 having a predetermined space is provided under the filter medium layer 314 . The water collecting space 315 is a place where clean filtered water from which particulate matter has been removed while passing through the filter medium layer 314 is collected. discharged to the outside

It is preferable that a washing unit 313 is further provided between the second swash plate 312 and the filter medium layer 314 . When raw water for filtration is passed through the filter medium layer 314 , particulate matter contained in the supernatant is removed from the filter medium layer 314 , but the particulate matter removed from the filter medium layer 314 closes the pores of the filter medium, so that the supernatant water is removed from the filter medium. It does not pass well through layer 314 . Therefore, it is common to perform a backwashing process of periodically or aperiodically washing the filter medium layer 314 after supplying and filtering the supernatant water for a certain time or a certain amount. Particles blocking the air gap between the contaminant particle layer 314 - 1 and the filter medium accumulated on the surface of the layer 314 fall off and the filtering performance is restored.

However, if the amount of the contaminant particle layer 314-1 accumulated on the filter medium layer 314 is too large, the backwash water supplied to the lower portion of the filter medium layer 314 does not pass well, and thus the backwashing efficiency decreases. do.

In the present invention, a washing unit 313 is further provided on the filter medium layer 314 to easily crush and disperse the contaminant particle layer 314-1, so that the filter medium layer 314 is backwashed very efficiently. There are advantages to being able to

Referring to FIG. 8, which is an enlarged perspective view of the washing unit, the washing unit 313 has a central axis so that one side of the second main conduit 319 penetrates and rotates freely, and a plurality of wings around the central axis. A plurality of branch pipes 313-3 extending from the rotating plate 313-1 to which the plate 313-2 is radially connected, the second main conduit 319 and positioned along the wing plate 313-2, and It consists of one or more nozzles 313-4 facing the wing plate 313-2 while being connected to the branch pipe 313-3. Here, the wing plate 313-2 is all inclined at the same predetermined angle, and the nozzle 313-4 is positioned in a direction perpendicular to the inclined surface.

The branch pipe 313 - 3 and the nozzle 313 - 4 communicate with the second main pipe line 319 , and the second main pipe line 319 has a second connection with the first main pipe line 318 . An auxiliary pipe 318-2 and a third valve 319-1 are provided. Therefore, when only air is supplied to the washing unit 331-3, the second auxiliary pipe 318-2 is closed and compressed air transferred from a compressor (not shown) is supplied. By opening the auxiliary pipe 318-2, air or backwash water can be selected.

In general, it is common to backwash the filter medium layer 314 only with air or water for backwashing, but in this case, it is difficult to expect a sufficient backwashing effect because a large amount of nozzles must be prepared and the air or backwashing water sprayed from the nozzles overlap each other.

However, in the present invention, the nozzle 313-4 for spraying air or backwash water faces the inclined blade plate 313-2, which induces rotation of the blade plate 312-2, and as a result, the filter medium layer 314 ) The vortex is generated on the surface to maximize the cleaning effect.

On the other hand, the filter unit 300 of the present invention further includes one or more vertically extending through-pipes 317 that sequentially pass through the first swash plate 311 , the second swash plate 312 , and the filter medium layer 314 . are being prepared

Specifically, the through pipe 317 is formed by passing through the through pipe first connection hole 311-2 of the first swash plate 311 and the through pipe second connection pipe 312 - 2 of the second swash plate 312 . After that, it is positioned to pass through the filter medium layer 314 again. Here, the through pipe 317 may be a cylindrical or square column with open upper and lower portions and closed sides, but is not limited thereto.

Therefore, the movement of the filtered water of the water collecting space 315 located under the filter medium layer 314 to the upper portion of the first swash plate 311 or the movement of the filtered water from the upper portion of the first swash plate 311 to the water collecting space 315 is Although possible, the raw water for filtration and backwash wastewater supplied between the first swash plate 311 and the second swash plate 312 or between the second swash plate 312 and the filter medium layer 314 flows into the through pipe 317 . can't be

The first filtering unit 300 of the present invention further includes a pressing member 316 on the first swash plate 311 to improve the backwashing effect of the filter medium layer 314 and to enable the operation of the filtering device with low energy, have.

9 which is an enlarged cross-sectional view of the pressing member, the pressing member 316 is located on the inner upper side of the filtering device body 310, has a predetermined size, and is elastic such as rubber that can expand and contract. made of material.

In addition, a pressing member fixing part 316-3 having one side fixed to the filtering device body 310 is provided above the pressing member 316, and a pressing member moving part 316-4 is provided below the pressing member 316. It is preferable to be further provided. The pressing member fixing part 316-3 supports the pressing member 316 to be fixed at a predetermined position of the filtering device body 310, and the pressing member moving part 316-4 is configured to contract and It is fixed only to the pressing member 316 to freely allow expansion.

Here, the pressing member moving part 316-4 is preferably in close contact with the inner wall surface of the filtering device body 310 so as to press the filtered water on the upper portion of the second swash plate 312 downward, and has a predetermined thickness. More preferably, it is made of a rubber or silicone material having elasticity.

For the expansion and contraction of the pressing member 316, a fluid supply pipe 316-1 and a fluid discharge pipe 316-2 are connected to one side of the pressing member 316, and inside the filtering device body 310, A water level sensor 310-1 is provided. That is, during backwashing of the filter medium layer 314, the water level sensor 310-1 continuously measures the water level above the first swash plate 311, and when the water level falls below a predetermined level, the fluid supply pipe 316-1 is opened. to expand the pressing member 316 by supplying a fluid. Conversely, when the backwashing of the filter medium layer 314 is finished, the fluid supply pipe 316-1 is closed and the outflow discharge pipe 316-2 is opened to induce the pressing member 316 to naturally contract.

On the other hand, a first main pipe line 318 for supplying raw water for filtration or discharging backwash wastewater to the outside is connected to the first main pipe connection hole 311-1 of the first swash plate 311, and the first The main conduit 318 is provided with first and second auxiliary conduits 318-1 and 318-2.
