Description

Water purification system {system for purifying water}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purification system, and more particularly, to a water purification system capable of effectively removing sediment sludge, sedimentation sludge, etc. present in a water body of a closed water body such as a pond.

In general, closed water bodies, such as natural or artificially-dried reservoirs or ponds, are mostly lacking or almost no influent. In such closed water bodies, water quality is severely contaminated if the rate of increase of naturally occurring and unspecified contaminants from outside exceeds the natural self-cleaning capacity, causing sedimentary sludge or sludge to be deposited on the bottom of the pond. .

The accumulated contaminants decay over time or rise above the water, causing odors, polluting water quality, and at the same time being a major cause of damage to the landscape. Therefore, the necessity of continuously removing such settling sludge or sedimentary sludge is absolutely required.

Conventionally, the general method for removing the sediment sludge or sedimentation sludge as described above was a method of draining all the water in the water body and dredging or discharging it using suction equipment. However, this method requires enormous manpower, time, and cost, and furthermore, as the pollutant increases again over time, it is inconvenient to repeat the pollutant removal operation periodically.

As another method of the related art, there is an attempt to inject a chemical into water or inject air to float a precipitate to remove it. However, when the body of water is very large, the removal efficiency is very low, it is very uneconomical to add the medicine and air injector and the removal of the injuries.

In view of the above, an apparatus for collecting sludge at all times in order to purify the water quality of the closed water is proposed. According to such an apparatus, a plurality of inlets are formed at the bottom of the pond, and these inlets are connected to the water purification apparatus through underground pipes. Therefore, the water quality is purified by inhaling the precipitate with water through the suction port at all times.

However, even in such a device, since sludge is sucked together with water through a narrow inlet, sludge in an area adjacent to the inlet can be removed, but sludge in an area farther away is not removed but is still deposited. . To this end, a large number of inlets may be installed at the bottom of the pond, but this is very uneconomical and, in particular, may seriously damage the water environment.

In addition, the conventional water purification system adopts a so-called 'bottom-up' filtration method in which contaminated water penetrates into the bottom layer, so that filtered contaminants or sludges are deposited on the bottom sand layer. Therefore, the bottom of the purified water is severely polluted, causing odor or inhibiting the hydraulic tube. Furthermore, in order to periodically remove the sediment contaminants, when the water flows in the reverse direction to backwash the filtration layer, the sediment contaminants or sludge floats on the surface of the pond, increasing the pollution of the purified water, and further, In order to send and remove a large amount of water must be flowed, so the removal efficiency is not only low but also very economical.

Therefore, there is an urgent need for means that can effectively filter and purify the water quality without contaminating the water quality of the purified water.

This is to prevent the vortex of the fluid at the time to ensure a stable and uniform flow.

The sludge filtration apparatus of the present invention may be installed and used directly below the purified water 200 as shown in FIGS. 1 and 2. In this case, various aquatic plants in the purified water 200 may be formed on the filtration layer 22 to maintain a natural landscape.

Reference numerals 75, 76, 77, and 78 which are not described in FIG. 2 indicate valves, respectively. Although the pipes between the sludge suction device 10 and the pump 40 and the sludge filtration device 20 have been described in detail in the present specification and drawings, the pipes between them may be modified within the scope of the technical idea of the present invention. Can be. For example, in the present embodiment, only one pump is used, but a plurality of pumps may be employed to be distinguished for each use.

Then, the operation of the water purification system of the present invention having the configuration as described above will be described.

In the operation of the water purification system of the present invention, first, the pump 40 is driven to suck the sludge together with the water in the lower body 100 through the suction pipe 30. Here, the valves 75 and 77 are in an open state, and the valves 76 and 78 are in a closed state.

The suction force by the pump 40 is transmitted to the suction members 11 and 11 'in communication with the suction pipe 30, and thus the first and second of the suction members 11 and 11'. Water and sludge are sucked through the suction holes 12a and 12b. At this time, since the first and second suction holes 12a and 12b are all formed in one direction, the suction members 11 and 11 'are shown in FIG. 4 by the reaction of sucking water and sludge. Likewise, it rotates counterclockwise. It is preferable that the size or length of the suction members 11 and 11 'be appropriately set in view of the magnetic force caused by the above reaction.

The rotation of the suction members 11 and 11 'exerts an effect of suctioning the sludge without recovering the sludge around the recovery port 110 to prevent the sludge from being deposited, and at the same time, more sludge is spread over a wide range. Allow for effective inhalation.

Subsequently, the sludge mixed water introduced into the inlet 41 of the pump 40 through the suction pipe 30 comes out of the outlet 42 of the pump 40, and then through the discharge pipe 50, the sludge filtration device 20. Flows into the settling portion 21b of the filtration case 21.

Then, the sludge mixed water flows into the discharge pipe 24 connected to the discharge pipe 50 end and is injected through the discharge port 24a. At this time, the discharge port 24a is inclined upward obliquely toward the strainer 23, so that the sludge mixed water injected therefrom hits the strainer 23. In addition, as shown in FIG. 7, since the discharge port 24a is formed at one side (for example, counterclockwise) on the side of the discharge tube 24, the discharge port 24a may react with the injection pressure of the sludge mixed water. The discharge tube 24 is rotated, for example, clockwise.

The operation as described above brings the characteristic effects of the present invention. First, the sludge mixed water is sprayed at an angle to the strainer 23 to act to desorb pollutants deposited or adsorbed on the strainer 23. do. Secondly, as the discharge tube 24 rotates, the sludge and water near the strainer 23 are stirred to further promote separation and filtration of the sludge.

Subsequently, the injected sludge mixed water flows upward through the filter layer 22 by pressure, in which sludge or contaminants are filtered out by the filter layer 22.

As a result, clean water from which the sludge is separated and filtered is discharged to the purified water 200, and then flows along the step water 300 to the lower water 100. Although the sludge filtration apparatus of the present invention is shown to be embedded directly below the purified water body 200 in the present embodiment, as another alternative, the water separated and filtered by the sludge filtration apparatus is passed through a separate passage. May flow to 200.

By repeating this process, the separated sludge is deposited on the bottom of the settling portion 21b in the filter case 21. If the sludge is deposited to some extent, it is removed by removing it out of the filter case 21, the process for this is as follows.

In the sludge discharge removal operation, the valves 75 and 77 are closed, the valves 76 and 78 are opened, and the pump 40 is driven. Then, the sludge accumulated at the bottom of the settling portion 21b through the sludge discharge pipe 60 is discharged together with the water. At this time, the back pressure is also applied to the filtration layer 22 so that the water flows downward, and the sludge or contaminants detained in the filtration layer 22 and the strainer 23 in this process are desorbed downward and the sludge together with the water. Exit to the discharge pipe (60). When the sludge is discharged, the perforated plate 70 serves to keep the flow uniform so that the fluid does not cause vortex.

Subsequently, the sludge discharged through the sludge discharge pipe 60 is discharged to the outside through the drain pipe 90.

The sludge discharge process does not have any effect on the purified water, and since the water flows downward due to the back pressure during the discharge of the sludge, there is no problem of contaminating water quality or floating of contaminants.

The sludge mixed water introduced through the suction pipe 30 is introduced into the housing 121 of the sludge filtration device 120 through the discharge pipe 150.

Then, the sludge mixed water flows into the discharge pipe 124 connected to the discharge pipe 150 and is injected through the discharge port 124a. At this time, since the discharge port 124a is inclined obliquely upward toward the lower strainer 123a, the sludge mixed water injected therefrom hits the strainer 123a. In addition, the discharge pipe 124 is rotated in the counterclockwise direction, for example. Rotation of the discharge tube 124 prevents the filter layer from being blocked by contaminants with sludge concentration.

 Subsequently, the injected sludge mixed water flows upward through the filter layer 122 by the pressure in the housing 121, in which sludge or contaminants are filtered out of the filter layer 122.

 Then, the water passing through the filtration layer 122 is discharged to the purified water 200 through the supply pipe 141, and then flows to the lower water 100 along the step water 300.

On the other hand, in the sludge discharge removal operation, after closing the valve 178, opening the valves 175, 176, and 177, the backwash pump 240 is operated. Then, the water in the upper body 200 is flowed back into the housing 121 along the back washing pipe 142 and is ejected through the back washing 224a of the back washing pipe 224.

At this time, since water is injected at a strong pressure through the backwashing holes 224a, the backwashing pipe 224 rotates in a counterclockwise direction, for example, in response to the spraying force. The rotation of the backwashing tube 224 allows an even pressure to be applied in the upper region of the housing 121 to efficiently detach the sludge adsorbed and held in the filtration layer 122.

More preferably, the compressor 340 is operated together with the operation of the backwash pump 240 to blow compressed air into the housing 121 through the auxiliary pipe 143. Then, water and compressed air flow downwards while the back pressure is further increased in the housing 121, and sludge or contaminants adsorbed and detained by the filtration layer 122 and the strainer 123a are moved downward in the process. As it is desorbed, it is discharged to the sludge discharge pipe 160 together with the water.

The water purification system of the present invention has the following advantages.

First, since water and sludge are sucked by the rotation of the suction member, sludge can be efficiently removed over a wider area while preventing sludge deposition or sedimentation.

Second, according to the water purification system of the present invention, since water and sludge are separated by rotary upflow filtration, it is possible to prevent the water quality of the purified water from being contaminated or inhibiting the hydraulic tube.

Third, the water and the sludge is filtered while the discharge member is stirred, thereby promoting the separation of the sludge and preventing deterioration of the function of the apparatus due to the adsorption of contaminants.

Fourth, since the suction means and the discharge means are rotated as a result of the reaction by the suction force or the earth output without a separate drive source, there is no need to additionally install a drive means such as a motor, so the structure is simple and the installation and manufacturing cost is also economical. .

Fifth, the sludge suction device of the present invention is concealed in the gravel, etc., and the sludge filtration device is also installed to be concealed under the purified water so as not to harm the hydraulic tube and the water environment at all to enable the implementation of an environmentally friendly system.
