Description

Water treatment system

The present invention relates to a water purification treatment of a water play-type hydroponic facility in which a fountain, a pond, a waterfall, a real stream, etc., which artificially store and circulate tap water, groundwater, etc., are open to the public among artificial facilities and contact the user's body to play in the water. As a water treatment system, the purified water by separating the sludge and pollutants contained in the water from the water is supplied back to the aquatic facility after a disinfection process, and the sludge and pollutants are stored and drained in the chamber to prevent contamination to the human body. About.

Unless otherwise indicated herein, the content described in this section is not prior art to the claims of this application, and inclusion in this section is not admitted to be prior art.

Recently, the number of children's play facilities for water play continues to increase and is mainly used in apartment houses and general hydroponic facility complexes.

Unlike general swimming pools, there are no shower facilities, and children are wearing clothes or shoes, so foreign substances are rapidly generated and polluted by turbidity, and a device and a sterilizer are used to remove foreign substances.

In addition, since it is a method of circulating water by operating a submersible pump in water, there are most cases where there is no machine room to install a water purification device, and it is difficult to apply a general water purification device.

Looking at the conventional water treatment system for water play facilities, there are registration number 10-1546880 "Water treatment system and method for water fountains and water play facilities", the first storage tank, the second storage tank, and a purification unit (macro filter and micro filter), and the second storage tank A water level control step in which the water level in the first storage tank is interlocked with the water level control, and the water in the second storage tank is filtered and purified by the purification unit through the control of the purification means of the pipe distribution unit and is supplied to the first storage tank. The control step, the bypass control step of supplying the water from the second storage tank to the first storage tank in an unpurified state through the control of the bypass means of the pipe distribution unit, and the control of the backwashing means of the pipe distribution unit. This is a system that performs a backwash control step in which water flows back to the purification unit to perform backwashing of the purification unit. Sticky substances and sludges containing oil among foreign substances clog the micro-filter, reducing the replacement life even if backwashing is performed. As a result, there is inconvenience and maintenance cost increase due to filter replacement, and it cannot be used in water facilities without machine room.

In addition, 10-1894277 filed for underwater use is a system in which a first filter unit and a second filter unit are provided, so that large substances are filtered by a brush in the first filter unit, and fine substances are filtered by a filter agent at the second filter unit. Therefore, depending on the type of foreign matter and the degree of contamination, the replacement cycle of the filter material is accelerated, and the backwashing efficiency is also reduced, there is an inconvenience of having to open the cover of the second filter unit and replace the filter material. Therefore, the conventional water treatment system for playing in the water has a problem in that the underwater filter method is difficult, and the filter must be replaced and the filter agent must be replaced.

One of the ways to solve the above problem, one of the methods of removing foreign substances from the water in general, the applied centrifugal type water treatment method registration number 10-1226599, foreign substances with a specific gravity greater than water by one centrifuge can be There is a method of separating foreign matters with small specific gravity and re-separating them using a first circulation and a coagulant, but it is not suitable for underwater use, and it is easy to separate foreign matters efficiently because one large centrifugal separator produces a single vortex. Not going

In addition, foreign substances with a small specific gravity are centrifuged again using a coagulant, which is inconvenient to use chemicals and is not good for the skin of children using water play.

Due to the nature of playing in the water, oil and waste oil from the human body cannot be treated with chemicals, and thus the purification system continues to circulate, contaminating the filter or causing equipment damage, causing problems in system operation.

Due to the nature of a water play facility, it is impossible to install a purification device between circulation pipes in water without a separate machine room.

The present invention is to solve the above-described problems, and is applied to a landscaping or aquatic facility, does not require periodic filter replacement, and provides a water treatment system for environmentally friendly removal without the use of chemicals such as coagulants to remove foreign substances in treated water.

Is formed, the outer cylinder 320 having a second discharge port (D2) for discharging the sludge is formed at the bottom, and is coupled to the inside of the outer cylinder 320 to be spaced apart from each other, and the supply pipe 120 is coupled to penetrate the inside, and It is composed of an inner cylinder 340 in which the first opening hole 341 is formed.

The centrifugal separation unit 200 is connected to the supply pipe 120 of the inner cylinder 340 and is vertically upwardly formed in the inner cylinder 340, and at the outer periphery of the upright pipe 220. Consisting of a branch pipe 240 that communicates but is connected horizontally, and a centrifugal separator 260 eccentrically coupled to the end of the branch pipe 240 and is installed inside the tank unit 300, By centrifugation, sludge with high specific gravity (p1) and particles with low specific gravity (p2) are separated from water.

The cover 360 is detachably coupled to the upper portion of the outer cylinder 320 and has a third outlet D3 for discharging the particles p2 having a low specific gravity.

The branch pipe 240 and the centrifugal separator 260 are configured by arranging a plurality of them in the circumferential direction on the outer peripheral surface of the upright pipe 220.

Each of the centrifugal separators 260 is formed in the upper lid 262 and the lower part of the lid 262, and the diameter decreases toward the lower part to form a cone shape, and a through hole 264 is formed in the lower part, and the lid It is vertically coupled to 262 and consists of a discharge pipe 266 having upper and lower opening holes.

The branch pipe 240 is coupled to be eccentrically connected to the side of the centrifugal separator 260.

The discharge pipe 266 is formed to have a diameter smaller than the diameter of the centrifugal separator 260, and the water discharged from the branch pipe 240 forms a vortex and rotates along the outer circumferential surface of the discharge pipe 266.

Therefore, the contaminated water flowing into the branch pipe 240 forms a vortex, while rotating the outer periphery of the discharge pipe 266 to exert a centrifugal separating force, and the relatively light particles (p2) move to the upper part and the heavy particles (p1) are lower Will go to.

A valve V1 mounted on the supply pipe 120 connected to the supply pump P to control on/off,

A bypass pipe 140 connected to the supply pipe 120 to both sides of the valve V1 to allow a part of the raw water to pass through, and a disinfectant supply unit 500 connected to the bypass pipe 140 are included.

Preferably, the valve (V1) is closed by about 30% so that water is moved to the bypass pipe 140, and the bypass pipe 140 has a venturi injector 160 having a diameter smaller than the diameter of the supply pipe 120 It is mounted so that the disinfectant can be supplied from the disinfectant supply unit 500 by the Venturi effect.

The disinfectant supply unit 500 supplies a gas obtained by individually or a mixture of ozone or oxygen stored in a chamber (not shown). Preferably, ozone: oxygen is preferably made to have a volume ratio of 4:6.

An electrolyzer 180 is formed in the supply pipe 120.

An ultraviolet sterilization lamp 350 is formed inside the outer cylinder 340.

The operation of the present invention configured as described above will be described as follows.

The water treatment system according to the present invention is installed in the water of the water storage tank 100.

The water is sucked and discharged by the supply pump P to be supplied to the water purification device, and the sterilizing gas is sucked and discharged from the venturi injector 10 to be supplied to the tank unit 300 to purify the water quality.

The sterilizing gas can achieve a greater sterilization effect by introducing ozone in addition to oxygen. Preferably, ozone:air has a volume ratio of 3 to 5: 5 to 7.

If the amount of ozone is more than the above, it is not helpful for the growth of fish or plants because it sterilizes beneficial microorganisms in the water.

Therefore, water treatment to increase sterilization power can be controlled by the amount of ozone.

The supply pipe 120 and the venturi injector 160 are installed to be interlocked so that they are introduced into the centrifugal separator 200 together with microbubbles to separate the material by a centrifugal separation method.

Foreign substances such as mud or sand having a large specific gravity fall down and accumulate in the lower portion of the outer cylinder 340, and foreign substances and treated water having a specific specific gravity less than water are discharged through the third outlet of the upper cover 360.

Foreign substances with a small specific gravity are mainly suspended substances, oil components, fine dust, etc. These foreign substances rise by themselves or are adsorbed and floated by microbubbles, and at the same time, microbubbles continuously rise upward and foreign substances cannot descend downward. Foreign matter stays inside the upper cover 360.

The water separated from the foreign matter is discharged to the third outlet D3, and the water purification work is completed.

Heavy foreign matter (sludge) deposited in the inner lower part of the outer cylinder is discharged by opening the second discharge port D2 and the drain valve V1 formed in the pipe,

The lightweight foreign matter remaining in the floating material chamber 362 in the upper cover 360 is discharged by opening the drain valve V3 of the pipe connected to the third outlet D3.

The on-off operation of the drain valve V3 may be driven by an automatic opening/closing device such as a timer.

The raw water introduced from the supply pipe 120 is moved through the granular pipe 220 and then introduced into the centrifugal separator 260 having a diameter of 20 mm and a length of 150 mm, and the flow rate is subdivided to increase the separation efficiency of water and sand.

In addition, the sterilizing gas is injected into the supply pipe 120 from the venturi injector 160 in the form of microbubbles.

Divided into a plurality of branch pipes 240 via the upright pipe 220, the eddy and eddy currents generated in the plurality of centrifugal separators 260 are once again transformed into microbubbles.

In this process, the microbubbles play a role in prolonging the contact time with the treated water and foreign substances, and this means that the sterilizing gas in the microbubbles gradually dissolves in the surrounding water, increasing dissolved oxygen and free radicals, a powerful disinfectant. It is generated, and it is advantageous for the upward movement operation by adsorbing light-weight foreign substances, so that foreign substances can be easily sent to the upper chamber.

In addition, when ozone gas is injected into the venturi injector 160, micro-ozone bubbles are generated, resulting in strong sterilization and cohesiveness with a high ozone absorption rate in water.

In this way, the microbubbles are discharged to the supply pipe 120, and contact with the highly oxidized ultraviolet sterilization lamp 350 to generate hydroxyl radicals (OH-), which are also powerful sterilants.

Meanwhile, the electrolyzer 180 is provided with a silver, copper and zinc ion alloy rod 182, and when a current of 5 to 12 DC Volt is applied to the alloy rod 182, water becomes an electrolyte and silver ions, copper ions and zinc Ions are generated and these ions remain in the water and improve the sterilization persistence.

These negative ions themselves sterilize the treated water and at the same time act as a catalyst for the highly oxidized UV lamp and ozone gas, accelerating the generation of hydroxyl radicals (OH-).

Although it has been described in connection with the preferred embodiment, it will be easily recognized by those skilled in the art that various modifications and variations are possible without departing from the gist and scope of the invention, and all such changes and modifications fall within the scope of the appended claims. Is self-explanatory.
