The first discharge pipe 21a and the second discharge pipe 21b connected to the drainage passages 11a and 12a of the water tub 10 and the water discharge unit respectively and the first and second discharge pipes 21a and 21b, A circulation pipe 22 provided with means 30 and a supply pipe 23 connected to the circulation pipe 22 and a water supply portion of the water tank 10 to form a circulation pipe 20,

The circulation pipe 22 is provided with a circulation pump 22a for filtering the water filled in the water tank 10 and supplying the water to the water tank 10 again.

The circulation pump 22a operates for approximately 24 hours when the swimming pool is used, so that purified water circulated for about six cycles per day is circulated.

A plurality of the circulation pumps 22a may be installed according to the capacity of the water tank 10 and may be installed to automatically stop when the water level of the water level adjustment tank 40 rises to a dangerous level.

The circulating pump 22a provided in the circulation pipe 22 is used to purify the contaminated water discharged from the water tank 10 through the purifying means 30 and then supply the purified water to the water tank 10 Circulation of water is performed.

In the circulation pipe 22, a collector 22b is installed at the front end of the circulation pump 22a.

The collector 22b is a strainer type filter having a size of about 5 mm or less and removes impurities such as hair, fibers, and metals contained in the water to prevent the pump from being damaged.

The collection mosquito 22b periodically performs the strainer cleaning using the differential pressure.

The pH adjuster is for preventing gradual alkalization of the water due to the chlorine-based disinfectant injected for sterilization in the disinfectant injector 23a to weaken the sterilizing power,

In this case, dilute hydrochloric acid or a pH enhancer is used as the pH adjuster.

Next, the purifying means (30) purifies the water circulated through the circulation pipe (20)

And a water softener (36) for passing water filtered by the filter (31) through a cation exchange resin to soften the water.

As shown in Fig. 2,

A filter material layer 33 formed by sequentially laminating filter media having relatively large specific gravity and large size and relatively small specific gravity and small filter media in the filtration tank 32 along the water circulation direction; Layer filter 31 that includes a filter portion composed of a filter layer 34 laminated on the layer 33. [

The gravel layer 33a, a first sand layer 33b having a relatively large specific gravity and a large size, a second sand layer 33c having a relatively small specific gravity and a medium size, A third sand layer 33d having a small size and an activated carbon layer 33e made of activated carbon are laminated in this order,

As the filter layer 34, a hydro filter is used.

Here, the water circulation direction means a direction in which the water introduced into the filtration tank 32 flows through the filter medium layer 33 and the filter layer 34 and flows out.

In the drawing, it is assumed that the water flows into the lower portion of the filtration tank 32 and is discharged to the upper portion of the filtration tank 32 after filtration. The gravel layer 33a, the first sandy layer The second sand layer 33c, the third sand layer 33d, the activated carbon layer 33e and the filter layer 34 are laminated in this order,

The gravel layer 33a, the first sand layer 33b, the second sand layer 33c, the third sand layer 33d, the activated carbon layer 33e and the filter layer 34 are sequentially arranged from the top of the filtration tank 32 to the bottom As shown in Fig.

The stacking order of the filter layer 34 and the filter layer 34 can be reversed depending on the size of the passage layer 33 or the size of the filter layer 34. In addition, May further increase or decrease the number of constituent layers, which is variable depending on the degree of contamination of the water flowing into the filtration tank 32, and the like.

The thickness of each of the layers and the particle size of the layer of the material layer 33 are not specified because they are determined by the degree of contamination of the water, turbidity, and the like.

Below the filtration unit, a strainer nozzle 32a for primarily removing foreign matters from the introduced water and injecting the water into the filtration unit is further installed.

The filtration unit formed by stacking the special filter medium and the hydrofilter having the above-mentioned structure can remove the turbidity by filtering the colloidal material of 0.01 micron or more contaminated with the water, and can remove the odor, taste and color of the water, Improvement and backwash volume can be minimized.

The filter 31 is configured such that filtration and backwashing can be automatically performed by the program automatically in accordance with the differential pressure or the filtration progress time.

3, the water softener 36 removes the hardness components of calcium (Ca) and magnesium (Mg) contained in the water,

An ionization tank 37 in which a cation exchange resin is stored and a control panel 39 for operating the operation of the salt water storage tank 38 and the water softener 36 in which brine is stored.

The cation exchange resin stored in the ionization cylinder 37 contains sodium (Na) ions and is composed of a polyvalent acid or base which is a polymer, and has strongly acidic or weakly acidic properties depending on the properties of groups to be substituted .

The cation-exchange resin of the river bed has a sulfonic acid group -SO 3 H as a group for performing ion exchange, and can be used in combination with a cation which is cation exchangeable over a wide pH range and which is strong base for softening of hard water and production of pure water.

The weakly acidic cation-exchange resin has a carboxyl group -COOH, which has a high ion exchange capacity and can be regenerated.

When the water is passed through the cation exchange resin, calcium ions and magnesium ions, which are hardness components of the water, exchange with the sodium ion of the cation exchange resin, and the hardness component is removed and the water is softened.

The salt water storage tank 38 regenerates cation exchange ability deteriorated through softening by passing the regenerant through the cation exchange resin of the ionization tank 37,

As the regenerant to be used at this time, brine in which 10% concentration of sodium chloride (NaCl) is dissolved is used.

In the water softener 36, the washing water is washed by passing the cation exchange resin upside down (backwashing), washing the foreign material between the resin layers, softening the resin layer, and then passing the salt water through the resin layer, The exchange of calcium ions and magnesium ions with the sodium ion of the brine is carried out, and the ion exchange ability of the cation exchange resin is regenerated again.

If the brine in the resin layer is washed with the washing water after the regeneration of the cation exchange resin using the brine reservoir 38, the resin layer which is unstable due to backwash is stabilized.

The water softener 36 is installed in the salt water reservoir 38 so that saline water is automatically filled for the next regenerating operation.

The present invention including the purifying means (30) having the above-described structure can continuously supply and manage the filtered water, and in particular, by softening the filtered water, the water is contaminated by the corrosion or scale of the pipe Can be prevented.
