Description

  The present invention relates to a technique for treating spring water generated in a closed space in a basement of a building such as a basement.

When the water level is lower than the groundwater level, there is a possibility that spring water may be generated in the underground part of the building, for example, a closed space in the basement of the building such as a basement.
Such spring water is groundwater filtered by the soil around the building, and therefore does not include fine particulate foreign matter such as muddy water.
Such springs are generally discharged into sewers and rivers through a pump connected to the pump and its discharge port.

However, the spring is affected by the soil and groundwater around the building. Then, for example, spring water by water via a concrete or the like, or spring water by water in contact with the ground improvement material becomes highly alkaline, and the drainage standard may not be cleared.
In addition, there are cases where spring water from contaminated soil contains pollutants and does not meet the standards for discharge into sewers and rivers.
In addition, spring water in contact with cement or soil conditioner contains calcium ions, which react with carbon dioxide in the air to produce calcium carbonate scale. For this reason, scales adhere to pump impellers and pipes that pump spring water containing calcium ions, and the scales grow, causing problems such as poor rotation of the impellers and blockage of the pipes (so-called “scaling failure”). There is also a case.
At present, no effective countermeasure technology has been proposed for the above-mentioned problem of spring water.

As another conventional technique, for example, an existing wall repair structure that improves the waterproof property of a wall in a basement of a building has been proposed (see Patent Document 1).
However, this prior art prevents water leakage from the walls of the basement, and once the water leakage occurs, the various problems described above cannot be solved.

JP 2001-132003 A

  The present invention has been proposed in view of the above-mentioned problems of the prior art. For example, spring water generated in a closed space in a basement such as a basement can satisfy drainage standards and discharge standards, In addition, the purpose is to provide a spring water treatment method for treating so that scales can be prevented from adhering and growing on the pump and pump.

  The spring water treatment method of the present invention is a closed space that exists below the groundwater level, and it is difficult to treat using chemicals (strong alkali such as caustic soda, strong acid such as hydrochloric acid and sulfuric acid, etc.). In the treatment method of spring water (W) generated in the space, ion exchange is performed inside the area near the location where the spring water is generated and upstream of the pump (pumping pump) that pumps the spring water (W) to the ground. A step of providing a spring treatment apparatus (10) containing the resin (3), and the ion exchange resin (3) is contained in the spring treatment apparatus (10) in a state of being filled in the cartridge (20). The spring water (W) is supplied to the spring water treatment device (10) containing the ion exchange resin (3) inside, and calcium (calcium ions) in the spring water (W) is removed by the ion exchange resin (3). Process, and the calcium (calcium In the step of removing (ON), the ion exchange resin (3) is immersed in the spring water (W), and the cartridge (20) filled with the ion exchange resin (3) when the ion exchange resin (3) is regenerated. ) Is removed from the spring water treatment device (10), the ion exchange resin (3) is moved to the ground side together with the cartridge (20), and chemicals (strong alkali such as caustic soda, strong acid such as hydrochloric acid and sulfuric acid, etc.) on the ground side. The spring treatment apparatus (10) includes a cartridge (20), a water conduit (5), and a drain pipe (6). The cartridge (20) is a container (1). ), A lid member (2), an ion exchange resin (3), and a water conduit (5) for introducing spring water from a spring water generation site (see FIGS. 3 to 5) into the spring water treatment device (10). , Ion exchange filled in lid member (2) and container (1) It penetrates the fat (3) and reaches the vicinity of the bottom of the container (1), and a plate-like member (7) is attached to the lower end (5a) of the water conduit (5). One end (6a) of the drain pipe (6) formed in (inverted U-shape) is at a level near the upper edge of the region filled with the ion exchange resin (3) of the container (1). The other end (6b) of the drain pipe (6) is connected to the pipe on the drain pump side.

In the present invention, it is preferable that the ion exchange resin (3) filled in the cartridge (20) is a mixture of a cation exchange resin and an anion exchange resin (uniformly).
Alternatively, a region (3A: or container) filled with a cation exchange resin and a region (3B: or container) filled with an anion exchange resin are provided in the cartridge (20), and the regions (3A, 3B) are connected in series. It is preferable to arrange.

  In this case, if the outer diameter of the container (1) is “D” and the height dimension of the container (1) is “H”, it is set so that H / D = 1.0 ± 0.1. Is preferred.

  Since the spring water (W) to be treated according to the present invention having the above-described configuration permeates the soil, the spring water (W) contains a substance other than a soluble substance (for example, an ionized substance). A soluble substance contained in the spring water to be treated is surely and easily purified by the ion-exchange resin (3) that does not contain, but reliably removes only ions.

For example, if the ions taken in by the ion exchange resin (3) are calcium ions, the calcium ions are completely removed from the spring water (W), so that the scale is attached to the pump and the pipe and grows. It is prevented.
As a result, it is possible to prevent the pump from being damaged or the piping being closed due to the adhesion / growth of the scale.

Moreover, the spring water treatment apparatus (10) used in the illustrated embodiment includes a cartridge (20) containing an ion exchange resin (3), and can be configured to be small as a whole.
Here, although it differs depending on the construction method of a closed space to which the present invention is applied, for example, in the case of a basement, measures for waterproofing are always taken, and a small amount of spring water (W) is generated. is there.
Therefore, even if the cartridge (20) containing the ion exchange resin (3) or the spring treatment apparatus (10) including the cartridge is small, a small amount of spring water (W) can sufficiently cope with it. It is.

  Then, by configuring the ion exchange resin (3) as a cartridge type, when it is necessary to regenerate the ion exchange resin (3), a space for treating spring water (W), for example, a basement of a building It is not necessary to regenerate the ion exchange resin (3) in a closed space. That is, in the illustrated embodiment in which the ion exchange resin (3) is configured as a cartridge type, it is not necessary to use chemicals such as acid (hydrochloric acid, sulfuric acid, etc.) or caustic soda in a closed space such as a basement.

According to the present invention, the regeneration of the ion exchange resin (3) is performed by removing the cartridge (20) containing the ion exchange resin (3) from the processing device (10) and removing the ion exchange resin ( 3) is performed by reproducing in an open space such as the ground. Therefore, it is an open place to regenerate using chemicals such as acid (hydrochloric acid, sulfuric acid, etc.) or caustic soda.
Therefore, the work of regenerating the ion exchange resin (3) using chemicals such as acid (hydrochloric acid, sulfuric acid, etc.) or caustic soda is performed safely (compared to the case where it is performed in a closed space such as a basement). It is.

  Further, according to the present invention, the spring water (W) is collected at one place (collected) and supplied to the ion exchange resin with a small pump, so that the spring water (W) is supplied to the ion exchange resin (3). It is also possible to keep the power for transporting to very low.

Furthermore, according to the invention, the structure of the device (10) is simple and compact. Therefore, the introduction cost can be kept low.
And maintenance is easy and the cost required for maintenance can be reduced.

In addition to this, according to the present invention, the ion exchange resin (3) is always kept immersed in the spring water (W) so that the ion exchange resin (3) touches the air. Therefore, it can always be kept immersed in water.
Therefore, the ion removal function in the spring water (W) by the ion exchange resin (3) is suitably exhibited.

In the present invention, when the outer diameter of the container (1) is “D” and the height dimension of the container (1) is “H”, the ratio “H / D” between the height dimension and the outer diameter is H / D. If D = 1.0 ± 0.1, the height (H) is smaller than the outer diameter (D) of the container (1). In some cases, the spring water can be introduced into the container (1) only by gravity even if the spring water generation site is a small (low) site from the basement floor.
In addition, the container (1) having a small height dimension (H) and a large outer diameter (D) has good stability and can be placed on the basement floor or the like without using a support or the like. . Even when the container (1) is kicked by the carelessness of a person entering or leaving the basement, the container (1) is extremely stable, and the container (1) falls over and breaks. And the spring water stored inside the container (1) is not spilled.

In the present invention, if the cation exchange resin and the anion exchange resin are uniformly mixed in the container (1) (or cartridge 20), the cation (calcium, sodium, lead) in the spring water can be obtained by a single cartridge. Etc.) as well as anions (chloride ions, sulfate ions, cyanide, etc.) can be suitably removed.
However, when the cation exchange resin and the anion exchange resin are mixed in the container (1) (or cartridge 20), when the ion exchange resin is regenerated, the cation exchange resin and the anion exchange resin Since the chemicals used for regeneration are different, the cation exchange resin and the anion exchange resin filled in the container (1) (or the cartridge 20) must be separated.
In contrast, a region (3A: or container) filled with a cation exchange resin and a region (3B: or container) filled with an anion exchange resin are provided in the cartridge (20), and the regions (3A, 3B) are provided. Can be taken out for each region or container (3A, 3B) and the ion exchange resin can be regenerated, eliminating the need to separate the cation exchange resin from the anion exchange resin. Become.

It is sectional drawing which shows the modification of 1st Embodiment. It is process drawing which shows the spring treatment process in 2nd Embodiment of this invention.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
1 to 11 show a first embodiment of the present invention.
First, with reference to FIG. 1, FIG. 2, the spring treatment apparatus used with the spring treatment method which concerns on 1st Embodiment is demonstrated.

In FIG. 1 and FIG. 2, the spring water treatment apparatus generally indicated by reference numeral 10 includes a cartridge 20, a water conduit 5, and a drain pipe 6.
The cartridge 20 includes a container 1, a lid member 2, an ion exchange resin 3, and a glass wool mat 4.
A female screw 21 is formed on the opening side of the lid member 2, and the female screw 21 is screwed with a male screw 11 formed on the outer periphery of the opening side (upper end) of the container 1.
In the lid member 2, through holes 22 and 23 are formed at two locations. A seal member (for example, rubber grommet) 8 made of an elastic material is provided in each of the through holes 22 and 23.
The water conduit 5 inserted in the through hole 22 is inserted into the container 1 through the through hole 22 and the seal material 8. One end 6 a of the drain pipe 6 is inserted into the container 1 through the through hole 23 and the seal member 8.

The glass wool mat 4 is arranged so as to be spread over the entire bottom of the container 1. The ion exchange resin 3 is filled in the region above the spread glass wool mat 4.
The lower end 5 a of the water guide pipe 5 penetrates the ion exchange resin 3 and reaches the inside of the region where the glass wool mat 4 is spread. And the plate-shaped member 7 is attached to the lower end 5a of the water conduit 5, This plate-shaped member 7 is later mentioned with reference to FIG.

Spring water from a spring water generation location (see FIGS. 3 to 5) is introduced into the container 1 in the spring water treatment apparatus 10 through the water conduit 5.
The drain pipe 6 has a first vertical portion 6c including one end portion 6a, a horizontal portion 6d, and a second vertical portion 6e including the other end portion 6b. U-shaped).
One end 6 a of the drain pipe 6 is disposed at a level near the upper edge of the region filled with the ion exchange resin 3. In FIG. 1, the other end 6 b of the drain pipe 6 is located near the lower end of the ion exchange resin 3 in the height direction position, and is connected to a drain pump side pipe (not shown).
The relationship between the symbols D ₁ and D ₇ in FIG. 1 will be described later.

In FIG. 1, the outer diameter of the container 1 is indicated by the symbol D, and the height dimension of the container 1 is indicated by the symbol H.
In the illustrated embodiment, the ratio H / D between the height dimension of the container 1 and the outer diameter is, for example,
H / D = 1.0 ± 0.1
It is set to become.

The container 1 having such a ratio has a smaller height dimension and a larger outer diameter as compared with a conventional cartridge. And since the height dimension of the container 1 is small, even if the spring generation location is the wall of the basement, even if the spring generation location is small (low) from the basement floor, Water can be introduced into the container 1.
Further, the container 1 having a small height dimension H and a large outer diameter D can be placed on the basement floor as it is without using a support or the like. Here, when placed on the floor of the basement, the container 1 may be kicked due to carelessness of a person entering or leaving the basement, but the container 1 falls down because the stability of the container 1 is good. The spring water stored inside is not spilled.

In the illustrated embodiment, the ion exchange resin 3 is used to purify the spring water generated in the basement of the building.
Here, the ion exchange resin 3 includes a cation exchange resin and an anion exchange resin.
When a cation (calcium, sodium, lead, etc.) is present in water, the cation exchange resin takes the cation into the resin and releases hydrogen ions (H ⁺ ).
When the ion exchange resin into which the cation is taken is immersed in an acid (hydrochloric acid, sulfuric acid, etc.) (regeneration), the acid (hydrochloric acid, sulfuric acid, etc.) takes in the hydrogen ion (H ⁺ ) and releases the cation.
On the other hand, when an anion (chloride ion, sulfate ion, cyanide, etc.) is present in water, the anion exchange resin takes in the anion into the resin and releases hydroxide ions (OH ⁻ ).
Here, when the ion exchange resin into which the anion is taken is immersed in an alkali solution (caustic soda solution, etc.) (regeneration), the alkali solution (caustic soda solution, etc.) takes in the hydroxide ion (OH ⁻ ) and releases the anion. .

In the illustrated embodiment, as the ion exchange resin 3, a cation exchange resin having an ability to remove calcium which is a cation is selected.
Here, by appropriately selecting an ion exchange resin, it is possible to remove ions other than calcium ions with the ion exchange resin.
For example, if it is in an ionic state, soil pollutants (specific harmful substances: for example selenium) can be removed.
In addition, if sodium and potassium are also removed from the spring water, calcium ions are surely removed from the spring water, making it difficult to deposit scale.

The spring water W flows into the spring water treatment device 10 through the water conduit 5, calcium ions and the like are taken in by the ion exchange resin 3, and the purified spring water W is pumped through the drain pipe 6 and is not shown. It is sent to the suction port of the pump.
As is apparent from FIGS. 1 and 2, the ion exchange resin 3 is completely immersed in the spring 4 when the spring W flows through the drain pipe 6.
And when the water level of the spring water W is located above the upper edge of the ion exchange resin 3, the end 6a of the drain pipe 6 is located below the water level of the spring water. 3 is completely immersed in the spring 4. As a result, the ion exchange resin 3 does not touch the air and is always maintained in a state of being immersed in spring water.

Here, in the spring water treatment apparatus 10 shown in FIGS. 1 and 2, the spring water that has flowed into the container 1 from the lower end 5 a of the water conduit 5 is drained through the region filled with the ion exchange resin 3. It goes out of the container 1 from the pipe 6.
Here, when the spring water passes through the region filled with the ion exchange resin 3, it does not pass through only a partial region of the ion exchange resin 3, but all the ions filled in the container 1. A plate-like member 7 is provided at the lower end 5a of the water conduit 5 so that the exchange resin 3 is routed uniformly.

The plate-like member 7 is formed in a conical shape having a gentle inclination (funnel shape) as a whole, and a spiral groove 71 (see FIGS. 8 and 9) is formed on the upper surface thereof, for example.
The spring water W that has flowed into the container 1 of the spring water treatment device 10 through the water conduit 5 flows along the spiral groove 71 from the center of the plate-like member 7 and flows along the spiral groove 71. Spring water flows from the entire area of the plate-like member 7 in the radial direction upward in FIGS. 1 and 2.
Details of the plate-like member 7 will be described later with reference to FIGS.

The ion exchange resin 3 does not exhibit an ion exchange function in a portion not in contact with the spring water, but the state where the ion exchange resin 3 is immersed in the spring water W is maintained in the spring water treatment apparatus 10 as shown in FIG. The ion exchange function is exhibited while being performed.
The ion exchange capacity of the ion exchange resin 3 is proportional to the surface area of the immersed ion exchange resin 3, and in the state shown in FIG. 1, all the ion exchanges filled in the container 1 of the spring water treatment apparatus 10. Resin 3 can exhibit its ion exchange ability.

Since the spring water treatment apparatus 10 shown in FIGS. 1 and 2 includes the cartridge 20 in which the ion exchange resin 3 is built, the entire structure can be made small.
Here, as will be described below with reference to FIG. 3, the illustrated embodiment is applied in a basement of a building or the like. And although it differs depending on the construction method, etc., the basement usually has measures for waterproofing, so the amount of spring water is small.
Therefore, even if the cartridge 20 containing the ion exchange resin 3 or the spring water treatment apparatus provided with the cartridge is small, it can be sufficiently dealt with.

Then, by configuring the ion exchange resin 3 as a cartridge type, when it is necessary to regenerate the ion exchange resin 3, the cartridge 20 containing the ion exchange resin 3 is removed from the processing apparatus 10, and only the removed cartridge 20 is removed. Is moved to an open space such as the ground, and the ion exchange resin 3 in the cartridge 20 is regenerated in the open space.
That is, according to the spring water treatment apparatus 10 shown in FIGS. 1 and 2, it is not necessary to regenerate the ion exchange resin 3 in a closed space such as a basement. In other words, in the cartridge-type spring treatment apparatus 10 shown in FIGS. 1 and 2, ion exchange resin using chemicals such as acid (hydrochloric acid, sulfuric acid, etc.) or caustic soda in a closed space such as a basement. No need to play 3

Next, the spring water treatment method according to the first embodiment will be described for each step with reference to FIGS.
FIG. 3 shows an example of a spring water generation point Gw when the spring water treatment method according to the first embodiment is carried out. The spring water generation location Gw exists above the wall surface F of the basement, for example.
In the example of FIGS. 3-7, the generation | occurrence | production location of the spring water W is upwards rather than the pumping pump which is not shown in figure.
Moreover, the location where the spring water W is generated is inside the closed space below the groundwater level. This is because there is no groundwater pressure at which spring water is generated unless it is a closed space below the groundwater level.

When supplying the spring water W to the spring water treatment apparatus 10 shown in FIGS. 1 and 2, it is necessary to prevent the scale water from being generated by mixing carbon dioxide into the spring water W.
4 to 6 show a process of supplying the spring 20 to the cartridge 20 without carbon dioxide mixing.
And in FIGS. 4-6, the process of attaching the spring treatment apparatus 10 shown in FIG. 1, FIG. 2 directly to the spring generation location Gw is shown.

In FIG. 4, the spring water generation site indicated by the symbol Gw in FIG. 3 is suspended in the V-cut portion Gv so that the spring water W can be easily guided to the spring water treatment device 10.
In FIG. 5, one end 9a of a pipe (for example, a vinyl chloride pipe) 9 is inserted into the V cut part Gv, and putty filling processing is performed on the part other than the pipe 9 in the V cut part Gv. In FIG. 5, after performing putty filling processing on the V-cut portion Gv in FIG. 4, an area where the putty filling processing has been performed is indicated by a symbol Pt.
In FIG. 5, the pipe 9 is attached so as to be inclined so that the end portion 9b side is downward.

In FIG. 6, the water conduit 5 is connected to the other end (lower end) 9 b of the pipe 9. Here, if the water guide pipe 5 is transparent, the flow of spring water can be easily seen. Of course, the water guide pipe 5 may be opaque.
As shown in FIG. 7 or as described with reference to FIGS. 1 and 2, the water conduit 5 is a part of the spring treatment apparatus 10. Therefore, although not clearly shown in FIG. 6, the water guide pipe 5 is provided with a spring water treatment device 10.

The spring water treatment apparatus 10 shown in FIGS. 1 and 2 can be provided in the vicinity of the spring water generation site by the steps shown in FIGS.
As a result, the flow path from the spring generation site Gw to the spring treatment device 10 is shortened, so that there is no need for a separate power source due to the head difference between the spring generation site Gw and a pump not shown. Water can be supplied to the spring water treatment apparatus 10.
Although not explicitly shown, the spring treatment apparatus 10 incorporating the ion exchange resin 3 is provided on the upstream side of a pumping pump (not shown).

Although not shown in FIGS. 1 to 7, when spring water is generated from a plurality of locations, the spring water is collected at one location (by collecting water) or a small pump (not shown) ) Can be supplied to the spring treatment apparatus 10 containing the ion exchange resin.
Further, even when the spring water generation site is the bottom of the closed space, it can be supplied to the spring water treatment apparatus 10 containing the ion exchange resin by a small pump (not shown).
If comprised in that way, it will become possible to suppress the motive power for conveying spring water to the spring treatment apparatus 10 incorporating ion exchange resin very small.

FIG. 8 shows a plate-like member 7 provided at the lower end portion 5a of the water conduit 5 of the spring water treatment apparatus 10 shown in FIGS.
The water guide pipe 5 is connected to the center of the plate-like member 7 whose planar shape (FIG. 9) is circular.
In FIG. 1, the diameter of the plate-like member 7 indicated by reference sign D ₇ is set smaller than the inner diameter D ₁ of the opening of the container 1. This is because the plate-like member 7 can be accommodated in the container 1.
The plate-like member 7 is formed in a taper shape so as to descend from the center position where the water conduit 5 abuts toward the outside in the radial direction. On the upper surface of the plate-like member 7, as shown in FIG. 9, a spiral groove 71 (in FIG. 9, a reference numeral 71 is attached to the center line of the groove) is formed.
In the end portion 5a of the water conduit 5, notches 5c are formed at a plurality of locations (four locations in the example of FIG. 8). The notch 5 c is formed to smoothly flow the spring water W that has flowed through the water conduit 5 into the spiral groove 71.

Although not clearly shown, the cross-sectional shape of the spiral groove 71 is semicircular.
As described above, the spiral groove 71 is formed so that the spring water flows from the entire radial direction of the plate-like member 7 toward the upper ion exchange resin 3.
8 and 9, a circular recess 72 is formed at the center position of the plate-like member 7. The circular recess 72 is smaller than the inner diameter of the water conduit 5 and communicates with the starting point of the groove 71. Therefore, the spring water introduced by the water guide pipe 5 once accumulates in the circular recess 72 and then flows along the spiral groove 71.
The circular recess 72 can be omitted, and in this case, the starting point of the spiral groove 71 communicates with the center point of the plate-like member 7, that is, the center point of the water conduit 5.

Instead of forming a spiral groove as shown in FIG. 9, a spiral passage (flow path) 73 may be formed inside the plate-like member 7A made of a porous material as shown in FIG. Is possible.
In FIG. 10, the front-end | tip 5a of the water conduit 5 is connected to the hollow 72 formed in the center of 7 A of plate-shaped members. A spiral passage (flow path) 73 also communicates with the recess 72.
With such a configuration, the spring water W supplied via the water conduit 5 flows through the spiral flow path 73 via the recess 72. While the spring water W flows through the spiral flow path 73, a part of the spring water permeates through the flow path formed by the open cell structure in the porous material constituting the plate member 7A. And it flows toward the ion exchange resin 3 from the upper surface of the plate-like member 7A.
As a result, the spring water W flows uniformly toward the upper ion exchange resin 3 from the entire area in the radial direction of the plate-like member 7A.
The spring water W that has flowed into the ion exchange resin 3 is reliably and easily purified by the action of the ion exchange resin 3 from the soluble substances contained in the spring water W (for example, substances in an ionic state).

Furthermore, as shown in FIG. 11, even if the spiral groove or passage is not formed, if the plate-like member 7B is made of a porous material, the spring water from the water conduit 5 is connected to the porous material. By the flow path formed with the bubble structure, it reaches uniformly over the entire radial direction of the plate-like member 7B.
Also in FIG. 11, the front end 5a of the water conduit 5 is connected to a recess 72 formed at the center of the plate-like member 7B.
The spring water W that has uniformly reached the entire radial direction of the plate member 7B flows into the ion exchange resin 3 filled above from the upper surface of the plate member 7B. And the soluble substance (for example, the substance which became an ionic state) contained in the spring water W is reliably and easily purified by the ion exchange action of the ion exchange resin 3.

1 to 11, in the container 1 (or cartridge 20), not only a cation exchange resin capable of removing calcium but also a cation exchange resin and an anion exchange resin are mixed. By doing so, not only calcium in spring water but also other cations (sodium, lead, etc.) and anions (chloride ion, sulfate ion, cyanide, etc.) can be removed.
However, when the cation exchange resin and the anion exchange resin are mixed in the container 1, when the ion exchange resin in the container 1 is regenerated, the cation exchange resin and the anion exchange resin are used for regeneration. Since the chemicals are different, the cation exchange resin and the anion exchange resin filled in the container 1 must be separated.

On the other hand, in the modification shown in FIG. 12, the cartridge 20 has a region or container 3A filled with the cation exchange resin and a region or container 3B filled with the anion exchange resin in the vertical direction (FIG. 1). (Vertical direction) are arranged in series. Here, although the partition 3W which divides the container 3A and the container 3B is not clearly illustrated, it is made of a material that can transmit spring water in the entire region. Accordingly, the spring water is configured to uniformly permeate from the lower side to the upper side in FIG. 1 over the entire radial direction of the container 1, the container 3A, and the container 3B.
In FIG. 12, when spring water permeates the container 3A, cations (calcium, sodium, lead, etc.) are removed with a cation exchange resin. And when spring water permeate | transmits the container 3B, an anion (a chloride ion, a sulfate ion, cyanide, etc.) is removed with an anion exchange resin.

Further, in the configuration as shown in FIG. 12, when regenerating the cation exchange resin filled in the container 3A and the anion exchange resin filled in the container 3B, each of the containers 3A and 3B is filled. The ion exchange resin may be taken out and regenerated.
That is, when regenerating the cation exchange resin in the container 3A, the cartridge 20 is removed, the container 3A is taken out of the cartridge 20, and the cation exchange resin filled therein is immersed in an acid (hydrochloric acid, sulfuric acid, etc.). It ’s fine. On the other hand, when the anion exchange resin in the container 3B is regenerated, the cartridge 20 is removed, the container 3B is removed from the cartridge 20, and the anion exchange resin filled therein is immersed in an alkaline solution (caustic soda solution or the like). It ’s fine.
In other words, according to the modification of FIG. 12, the operation of separating the cation exchange resin and the anion exchange resin as in the case where the cation exchange resin and the anion exchange resin are mixed in the container 1 is performed. It becomes unnecessary.

  Other configurations and operational effects in the modified example of FIG. 12 are the same as those of the first embodiment of FIGS.

Next, a second embodiment of the present invention will be described based on FIG.
In FIG. 13, the spring water treatment apparatus according to the second embodiment, indicated as a whole by reference numeral 10 </ b> A, includes a cartridge 20 </ b> A, a transparent resin water guide pipe 5, and a drain pipe 6 </ b> A.
The cartridge 20A has a cylindrical member 1A, a lid member 2A, and silica wool 3A that is a cation exchange resin.

The water guide pipe 5 penetrates the lid member 2A, and the lower end portion 5a of the water guide pipe 5 is disposed in the vicinity of the lid member 2A.
The silica wool 3A is filled so as to be in contact with the inner periphery 1Ai and the bottom 1Ab in the cylindrical member 1A.
The drain pipe 6A includes a first U-shaped portion 61A, a first vertical portion 62A, a second U-shaped portion 63A (inverse U-shaped in FIG. 13), a second vertical portion 64A, and a discharge portion 65A. have.
One end (first U-shaped portion 61A) of the drain pipe 6A communicates with the bottom 1Ab of the cylindrical member 1A.

In the spring water treatment apparatus 10A of the second embodiment, when the cylindrical member 1A is filled with the spring water W by making the drain pipe 6A U-shaped, silica wool that is an ion exchange resin 3A does not touch the air, and is always kept in the spring water W.
In FIG. 13, the spring water W is discharged from the drain pipe 6 </ b> A. However, the drain pipe 6 </ b> A can be connected to a suction port of a pump not shown and pumped to the ground side by the pump and discharged. is there.

In the illustrated embodiment, the spring water to be treated passes through the soil and is filtered through the soil, so that the spring water does not contain any substance other than a soluble substance (for example, an ionized substance). That is, the spring water contains no ions other than ions.
In the illustrated embodiment, since an ion exchange resin that reliably removes only ions is used, the soluble substance contained in the spring water to be treated is reliably and easily purified.

For example, if the ions taken in by the ion exchange resin are calcium ions, the calcium ions are completely removed from the spring water, so that scales are prevented from adhering to the pump and piping and growing.
As a result, it is possible to prevent the pump from being damaged or the piping from being closed due to the adhesion and growth of the scale.

Moreover, the spring water treatment apparatus 10 and 10A used by embodiment of illustration is equipped with the cartridge 20 and 20A which incorporates ion exchange resin, and can comprise the whole small.
Here, although it differs depending on the construction method of the closed space to which the illustrated embodiment is applied, for example, in the case of a basement, measures for waterproofing are always taken, and a small amount of spring water is generated. .
Therefore, even if the cartridges 20 and 20A containing the ion exchange resin or the spring treatment apparatuses 10 and 10A including the cartridge are small, a small amount of spring water can sufficiently cope with it.

  Then, by configuring the ion exchange resins 20 and 20A as a cartridge type, when it is necessary to regenerate the ion exchange resins 3 and 3A, a space for treating the spring water W, for example, a closure like a basement of a building From the space, the cartridges 20 and 20A filled with the ion exchange resins 3 and 3A may be transported to, for example, the ground side and regenerated on the ground side. That is, in the illustrated embodiment in which the ion exchange resins 3 and 3A are configured as a cartridge type, there is no need to perform a regeneration operation using chemicals such as acid (hydrochloric acid, sulfuric acid, etc.) or caustic soda in a closed space such as a basement. .

Therefore, in the illustrated embodiment, the regeneration work using chemicals such as acid (hydrochloric acid, sulfuric acid, etc.) or caustic soda can be performed in an open place.
Therefore, the work of regenerating the ion exchange resins 3 and 3A using a chemical such as acid (hydrochloric acid, sulfuric acid, etc.) or caustic soda is performed safely (compared to the case where it is performed in a closed space like a basement). It is.

  Moreover, in embodiment of illustration, the power for conveying spring water to ion-exchange resin by collecting spring water in one place (collecting water) and supplying it to ion-exchange resin with a small pump is extremely high. It can be kept small.

Furthermore, in the illustrated embodiment, the structure of the spring water treatment apparatus 10, 10A is simple and compact. Therefore, the introduction cost can be kept low.
In addition, maintenance is easy and the cost required for maintenance can be reduced.

In addition, in the illustrated embodiment, since the ion exchange resins 3 and 3A are always maintained in a state of being immersed in spring water, the ion exchange resins 3 and 3A are not exposed to the air and are always in contact with the air. The state immersed in the spring water W can be maintained.
Therefore, the ion removal function in the spring water W by the ion exchange resins 3 and 3A is suitably exhibited.

The illustrated embodiment is merely an example, and is not intended to limit the technical scope of the present invention.
For example, in the illustrated embodiment (first embodiment), the spring water W is supplied from the water conduit 5 to the spring water treatment apparatus 10 and discharged from the spring water treatment apparatus 10 through the drain pipe 6. However, it is also possible to supply the spring water W from the drain pipe 6 to the spring water treatment apparatus 10 and discharge it from the water conduit 5.
In that case, the same plate-like members 7, 7A and 7B as in FIGS. 8 to 11 are connected to the drain pipe 6, and the spring water W supplied to the spring treatment apparatus 10 through the drain pipe 6 is spring water. It is preferable that the ion exchange resin 3 in the processing apparatus 10 penetrates evenly in the entire radial direction.
In the illustrated embodiments (first embodiment, second embodiment), calcium is removed from the spring water by the ion exchange resins 3 and 3A, but heavy metal ions and other ions are removed from the spring water. Is possible.
