Description

Mineral water treatment device {MINE DRAINAGE TREATMENT APPARATUS}

The present invention relates to an apparatus for treating mineral water, and more particularly, to achieve minimum land use, high treatment efficiency, and low maintenance cost through a forward osmosis process, which is a low-energy system, and to reduce available metals and ions contained in mineral water. It relates to a mineral water treatment device capable of recovering minerals and recycling treated water into water-soluble fertilizer.

In general, mine water is discharged from mines. Mineral water is treated using an active treatment method and a natural purification method.

In the active treatment method, the treatment speed of mineral water is fast, but the minerals contained in the mineral water remain in the solution. Therefore, since an additional process is required to process the mineral material, the processing cost is increased compared to the natural purification method.

In the case of the natural purification treatment method, environmentally friendly treatment is possible, but the treatment speed of light treatment water is delayed. The natural purification treatment method requires a large site area like the existing sewage treatment plant because the increase in the treatment process and the contact area of the wastewater affect the treatment amount.

In addition, in the case of the natural purification method, heavy metals are removed using microorganisms in an alkali supply tank. However, since microorganisms are greatly affected by their growth rate and activity environment, it is necessary to develop organic materials for microorganisms. In addition, there is a problem that a sufficient contact time with wastewater is required, and a difference in treatment efficiency occurs depending on the temperature difference according to the season.

The background art of the present invention is disclosed in Republic of Korea Patent Publication No. 2017-0047089 (published on May 4, 2017, title of the invention: membrane bioreactor-osmosis microbial fuel cell fusion water treatment system and water treatment method).

1 is a circuit diagram showing an apparatus for treating mineral water according to an embodiment of the present invention.

Referring to FIG. 1, a mineral water treatment device according to an embodiment of the present invention includes a mineral water positive osmosis tank 10, an induction solution tank 20, an ultra treatment tank 30, a mineral water tank 40, and It includes a mineral recovery tank (50).

In the mineral water forward osmosis tank 10, a forward osmosis membrane 11 is installed to divide the mineral water accommodating part 12 and the induction solution accommodating part 13. In the mineral water forward osmosis tank 10, as the mineral water in the mineral water receiving unit 12 passes through the forward osmosis membrane 11 and flows into the induction solution receiving unit 13, minerals are filtered by the forward osmosis membrane 11. . The forward osmosis membrane 11 is vertically disposed in the mineral water forward osmosis tank 10 . A mine water accommodating unit 12 is disposed on one side of the forward osmosis membrane 11, and an induction solution accommodating unit 13 is disposed on the other side of the forward osmosis membrane 11.

Mineral water contains minerals. Minerals refer to fine substances such as heavy metals and ionized substances mixed in water.

The induction solution tank unit 20 supplies the induction solution to the induction solution receiving unit 13, and the induction solution diluted in the mineral water forward osmosis tank 10 is recovered in the induction solution tank unit 20. The mineral water forward osmosis tank 10 and the induction solution tank unit 20 are connected by a dilute induction solution discharge pipe unit 21.

In addition, the induction solution tank unit 20 further includes a concentrating agitator 25 installed to concentrate the diluted induction solution while agitating it. Since the induction solution and the treated water are separated as the concentration agitator 25 rotates, the induction solution is concentrated to a relatively high concentration. Here, mineral water separated from the induction solution is defined as treated water.

The apparatus for treating mineral water further includes a concentrated induction solution supply pipe 22 and a concentrated induction solution pump 23 .

The concentrated induction solution supply pipe 22 is connected to the induction solution tank 20 and the mineral water forward osmosis tank 10, and supplies the concentrated induction solution in the induction solution tank 20 to the mineral water forward osmosis tank 10. do. The concentrated induction solution pump 23 is installed in the concentrated induction solution supply pipe 22. As the concentrated induction solution pump 23 is driven, the concentrated flow solution in the mineral water forward osmosis tank 10 is recovered through the concentrated induction solution supply pipe 22 . Since the concentrated induction solution is recovered in the mineral water forward osmosis tank 10, the concentration of the induction solution in the mineral water forward osmosis tank 10 can be restored to a high concentration. In addition, since it is not necessary to continuously supply a new induction solution to the mineral water forward osmosis tank 10, the treatment cost of mineral water can be reduced.

In addition, the induction solution may be replenished in the induction solution tank unit 20 at regular intervals. Therefore, the amount of the induction solution used in the induction solution tank unit 20 can be reduced.

The induction solution tank part 20 and the ultra treatment tank 30 are connected by a treated water discharge pipe part 47, and a treated water pump 48 is installed in the treated water discharge pipe part 47. As the treated water pump 48 is driven, the treated water separated from the induction solution tank 20 is supplied to the ultra treatment tank 30 through the treated water discharge pipe 47 .

An ultrafiltration membrane 31 is installed in the ultrafiltration tank 30 to filter the treated water supplied from the induction solution tank 20, and the treated water filtered by the ultrafiltration membrane 31 is discharged to the outside. In the ultra-treatment tank 30, a small amount of the induction solution and treated water pass through the ultra-filtration membrane 31 and then are discharged to the outside. A small amount of diluted induction solution and treated water discharged from the ultra treatment tank 30 may be used as water-soluble fertilizer.

The mine water treatment device has an induction solution recovery pipe unit that connects the induction solution tank unit 20 and the ultra treatment tank 30 and recovers the induction solution filtered in the ultra treatment tank 30 to the induction solution tank unit 20 ( 33) is further included. Since the draw solution separated by the ultrafiltration membrane 31 is returned to the draw solution tank 20, it is not necessary to continuously supply the draw solution to the draw solution tank 20. In addition, since most of the induction solution is recovered from the ultratreatment tank 30 and then supplied again to the induction solution tank 20, the amount of the induction solution discharged from the ultratreatment tank 30 can be reduced. Therefore, the treatment cost of mineral water can be reduced.

The mineral water tank unit 40 supplies mineral water to the mineral water accommodating unit 12, and the mineral water tank unit 40 collects minerals and mineral water filtered by the mineral water positive osmosis tank 10. In the mineral water forward osmosis tank 10, minerals are separated by the forward osmosis membrane 11, and the separated minerals are recovered back to the mineral water tank unit 40. Mineral materials are stacked on the lower side of the mineral water tank unit 40 .

A raw water supply pipe 41 is connected to the mineral water tank 40 to supply external mineral water, and a raw water pump 42 is connected to the raw water supply pipe 41 . As the raw water pump 42 is driven, the mineral water is supplied to the mineral water tank 40 .

The gas tank unit 60 and the mineral water tank unit 40 are connected by a gas supply pipe unit 61. Since the gas tank unit 60 supplies gas to the mineral water in the mine water tank unit 40, the mine water tank unit 40 functions as an aeration tank. Since gas is supplied to the mineral water to adjust the pH level, and organic substances are adsorbed and oxidatively decomposed by aerobic bacteria, the minerals contained in the mineral water precipitate to the bottom of the mineral water tank 40 and become sludge. Therefore, the mineral material and the mineral water can be easily separated in the mineral water tank unit 40 .

The mineral water tank unit 40 further includes a separating agitator 45 that separates minerals by agitating the mineral water supplied to the mineral water tank unit 40 . Since the separation stirrer 45 agitates the mineral water, the gas is more evenly mixed with the mineral water. Therefore, the decomposition performance of aerobic bacteria can be improved.

The mineral water tank unit 40 and the mineral recovery tank 50 are connected by a mineral discharge pipe unit 52, and a mineral pump 53 is installed in the mineral discharge pipe unit 52.

In the mineral material recovery tank 50, a separator 51 is installed to separate minerals and mineral water, and in the mineral material recovery tank 50, the mineral material and the mineral water supplied from the mineral water tank 40 are separated by the separator 51. do. Since the mineral material and the mineral water are separated by the separator 51, the mineral water is discharged to the outside and the mineral material can be recovered. Therefore, it is possible to recover and recycle the minerals contained in the mineral water, and to collect contaminants such as heavy metals contained in the mineral water.

The mineral water in the mineral water accommodating unit 12 passes through the forward osmosis membrane 11 and flows into the induction solution, and as the mineral water is mixed with the induction solution, the concentration of the induction solution is diluted. The diluted induction solution in the induction solution accommodating part 13 is supplied to the induction solution tank 20 through the dilute induction solution discharge pipe 21 .

When the concentration agitator 25 is driven in the induction solution tank 20, the induction solution and the treated water are stirred, thereby separating the induction solution and the treated water. As the draw solution and treated water are separated, the draw solution is concentrated again.

The induction solution concentrated in the induction solution tank part 20 is supplied back to the induction solution receiving part 13 through the concentrated induction solution supply pipe part 22. In addition, as the treated water pump 48 is driven, the treated water separated from the induction solution tank 20 is supplied to the ultra treatment tank 30 through the treated water discharge pipe 47 .

In the ultra-treatment tank 30, a small amount of the induction solution and treated water pass through the ultra-filtration membrane 31 and then are discharged to the outside. A small amount of diluted induction solution and treated water discharged from the ultra treatment tank 30 may be used as water-soluble fertilizer.

In addition, since the draw solution separated by the ultrafiltration membrane 31 is returned to the draw solution tank 20, it is not necessary to continuously supply the draw solution to the draw solution tank 20. In addition, since most of the induction solution is recovered from the ultratreatment tank 30 and then supplied again to the induction solution tank 20, the amount of the induction solution discharged from the ultratreatment tank 30 can be reduced. Therefore, the treatment cost of mineral water can be reduced.

Minerals and mineral water in the mineral water tank unit 40 are agitated by a separate stirrer 45, and gas is supplied to the inside of the mineral water tank unit 40 from the gas tank unit 60. Since the gas tank unit 60 supplies gas to the mineral water in the mineral water tank unit 40, the pH concentration of the mineral water can be adjusted, and organic substances can be adsorbed and oxidatively decomposed by aerobic bacteria. Therefore, since the mineral substances contained in the mineral water precipitate to the lower portion of the mineral water tank unit 40 and form sludge, the minerals and the mineral water can be easily separated in the mineral water tank unit 40.

When gas is supplied to the mineral water tank unit 40 and the separation agitator 45 is driven, mineral water is not supplied to the mineral water tank unit 40 from the outside.

Minerals precipitated in the mineral water tank unit 40 are supplied to the mineral recovery tank 50 through the mineral discharge pipe unit 52 . In the mineral material recovery tank 50, since the mineral material and the mineral water are separated by the separator 51, the mineral water is discharged to the outside and the mineral material can be recovered. Therefore, it is possible to recover and recycle the minerals contained in the mineral water, and to collect contaminants such as heavy metals contained in the mineral water.

As described above, in the mineral water forward osmosis tank 10, the mineral water is treated by applying the forward osmosis membrane 11. Therefore, it is possible to reduce the site area for treating mineral water, and to achieve treatment of chemical species and heavy metals in acidic mineral water with low energy consumption, thereby reducing treatment cost of mineral water.

In addition, since the gas of the gas tank 60 is supplied to the mineral water tank 40 and the separation agitator 45 stirs the treated water in the mineral water tank 40, the mineral water tank 40 Minerals such as heavy metals and ions can be recovered through pH control and aeration of acidic mineral water. In addition, since the induction solution diluted in the mineral water tank unit 40 is separated in the ultratreatment tank 30, the treated water discharged from the ultratreatment tank 30 can be used as a water-soluble fertilizer.

In addition, since the high-concentration induction solution filtered in the ultratreatment tank 30 is returned to the induction solution tank unit 20, the induction solution can be recycled. Therefore, the treatment cost of mineral water can be reduced.

In addition, since the minerals separated from the forward osmosis membrane 11 are separated from the mineral water tank unit 40 and then recovered in the mineral material recovery tank 50, the recovery rate of concentrated minerals such as heavy metals and ions can be increased. there is.

Next, an apparatus for treating mineral water according to another embodiment of the present invention will be described. In another embodiment of the present invention, since the mineral material recovery tank and the gas tank part are substantially the same as the one embodiment except that the gas tank part is deleted, the same drawing numbers will be assigned to the same configurations below and the description thereof will be omitted.
