Hereinafter, a purification apparatus and a method for supplying grass water according to the present invention will be described in detail with reference to the drawings.

1. Description of purifier for supplying grass water for golf course

The purifier according to the present invention is in fluid communication with a golf course fond 400.

The control unit 300 includes a floating separation unit 210, a pretreatment water branching control unit 220, a membrane filtration unit 230 and a storage tank 240. The control unit 300 controls each of them. The control unit 300 includes a water treatment sensor unit 310, a water treatment control unit 320, and a grass water control unit 330.

(1) Injury Separating portion (210)

The floating separation unit 210 is in fluid communication with the pond 400 through a plurality of suction pipes 511 and 521 and outflow pipes 512 and 522. The floating water separator 210 performs solid- To generate a preprocessed water.

The floating separation unit 210 is controlled by the water treatment control unit 320 according to the water quality of the fountain sensed by the water treatment sensor unit 310. That is, when the water quality sensed by the water treatment sensor unit 310 does not meet the preset water quality standard, the number of fountains is controlled to flow into the floating separation unit 210.

In another embodiment of the present invention, the water treatment control unit 320 may control the flotation separation unit 210 so that only a part of the fountains in the fond can be controlled.

That is, the suction pipes 511 and 521 are composed of a first series suction pipe 511 and a second series suction pipe 521, and the outlet pipes 512 and 522 are composed of a first series outlet pipe 512 and a second series Series outflow pipe 522, it is necessary to detect the water quality of the fins of the first series suction and discharge pipes 511 and 512 and the fins of the second series suction and discharge pipes 521 and 522, If the water quality of the series does not meet the water quality standard of the water quality, it is possible to introduce only the number of the water of the series.

For this purpose, the series branch control unit 550 controls the branch of the first series suction pipe 511 and the second series suction pipe 521 and the branch of the first series discharge pipe 512 and the second series discharge pipe 522 Can be controlled.

In one embodiment of the present invention, the water quality standard of the fountain sensed by the water treatment sensor unit 310 may be composed of the pH of the fountain, dissolved oxygen (DO), turbidity, and the like.

Accordingly, when the dissolved oxygen (DO) of the fond number is 2 to 5 mg / L, the floating separation unit 210 can be controlled to inject minute bubbles into the fond number.

When the pH of the fountain water is less than 5.0, the floatation separator 210 is controlled to inject alkaline chemicals into the fountain water. When the pH of the fountain water is more than 8.0, Injection.

Meanwhile, the floating separation unit 210 may use dissolved air flotation (DAF) or electro flotation (EF). The dissolved air floating method (DAF) may use at least one of pressurized air and decompressed air. Detailed description of each flotation method is omitted in the prior art.

The separation material separated in the floating separation unit 210 may be separated by a separate scraper (not shown) and collected in the separation material storage tank 215.

(2) Preprocessing number  The branching controller 220,

The pretreatment water branch control unit 220 may supply the pre-treatment water introduced from the flotation separation unit 210 to the fondant 400 or supply it to the membrane filtration unit 230.

These branches may be manually controlled or may be automatically controlled by the turf water control unit 330. [

This is because the pretreatment water pretreated by the flotation separation unit 210 is not suitable for use as lawn water as it is.

Therefore, by using the preprocessing water branch control unit 220, it is possible to re-supply the preprocessed water to the pond when the water quality of the pond water is required to be maintained or when the number of pond water is insufficient as in the wet season, When it is desired to supply water as the water, the membrane filtration unit 230 can perform the main treatment.

In an embodiment of the present invention, when the grass water control unit 330 automatically controls the grass water control unit 330, the grass water control unit 330 detects the storage amount of the grass water storage tank 240, which is an existing facility, If not, the pre-treatment water can be controlled to flow into the membrane filtration unit 230.

Of course, when there is no grass water storage tank 240 or the automatic control system is not adopted, it is controlled so that the pre-treatment water is introduced into the membrane filtration unit 230 manually or periodically according to a predetermined period by the user, The grass water treated mainly in the water storage tank 230 may be temporarily stored in the grass water storage tank 240 or may be supplied directly to the grass.

(3) The filtration part (230)

The membrane filtration unit 230 subjects the pretreated water supplied from the pretreatment water branch control unit 220 to main treatment using a membrane filtration process.

The membrane filtration section 230 includes a separation membrane for the membrane filtration process.

In one embodiment, the separation membrane may be a microfiltration membrane (MF) or an ultrafiltration membrane (UF) of 0.001 to 1 μm.

In another embodiment, the separator is formed of a polymer selected from the group consisting of polyethylene (PE), polysulfone (PS), polyethersulfone (PES), polyacrylonitrile (PAN), polyvinylidene fluoride (PVDF), or polytetrafluoroethylene Or a ceramic film made of aluminum oxide or silicon carbide.

In another embodiment, the separation membrane may be a submerged membrane or a pressurized membrane.

In another embodiment, the separation membrane may be an external pressure membrane or a pressure-resistant membrane.

In another embodiment, if the separator is a submerged separator, the pressure applied is preferably greater than -1 bar to less than 0 bar, or the pressure applied to the separator may be less than 10 bar above 0 bar if the separator is a pressurized separator.

It is needless to say that the type, material, application conditions, and the like of the separation membrane can be easily selected by the user depending on the type of golf course, pond, or lawn.

On the other hand, it is needless to say that the separation membrane is contaminated depending on use and needs to be cleaned. Such cleaning can be done automatically by detecting the contamination level by a separate sensing unit, or manually or by a predetermined time unit.

The separator may be cleaned by physical cleaning or chemical cleaning. Here, physical cleaning refers to cleaning with air, water, steam, or acid or alkali chemicals of less than 500 mg / L, and chemical cleaning means cleaning with acid or alkali chemicals of 500 mg / L or more.

2. Explanation of how to supply grass water

First, the water treatment sensor unit 310 senses the water quality of the fountain water.

If the sensed water quality does not meet the preset water quality standard, the water treatment control unit 320 introduces the number of fins into the flotation separation unit 210.

Here, the water treatment sensor unit 310 may introduce only the number of fingers in a specific area by using sensors located in various places within the fond 400.

In one embodiment, the water quality of the fins of the first series suction and discharge pipes 511, 512 and the second series suction and discharge pipes 521, 522 are respectively sensed, and the water quality of the suction and discharge pipes of any one series If it does not meet the preset water quality standard, only the number of fountains can be introduced into the floating separation unit 210.

Next, the floating separation unit 210 generates a preprocessed water by subjecting the introduced fond number to solid-liquid separation and pre-processing.

Next, when the preset condition is satisfied, the pre-treatment water branch controller 220 introduces the pre-treatment water into the membrane filtration unit 230.

The predetermined conditions here can be the same as the automatic or the number.

In one embodiment, when the turf water control unit 330 detects the amount of turf water storage tank 240 and does not meet the preset criteria, the turf water control unit 330 recognizes the turf water supply command by the turf water control unit 330 220 may operate.

Next, the pretreatment water flowing into the membrane filtration unit 230 is subjected to membrane filtration treatment to generate main treatment water, which is supplied as turf water.

On the other hand, the degree of contamination of the separation membrane of the membrane filtration unit 230 is sensed periodically or irregularly, and if the degree of contamination corresponds to a preset contamination standard, the separation membrane can be physically cleaned or chemically cleaned.

Although the preferred embodiments of the present invention have been described, the present invention is not limited to the specific embodiments described above. It will be apparent to those skilled in the art that numerous modifications and variations can be made in the present invention without departing from the spirit or scope of the appended claims. And equivalents should also be considered to be within the scope of the present invention.
