Water treatment system using electrolysis ozone generator {A Ozone Oxidation Equipment And System Using It}

The present invention relates to a water treatment system using an electrolysis ozone generator, and more particularly, it is possible to freely adjust the concentration of ozone water according to the concentration of pollution, and H _₂ generated by _retaining raw water passing through a cathode electrode for a predetermined time. The present invention relates to a water treatment system by electrolysis-type ozone generation for water treatment in accordance with drinking water quality standards by purifying oxidation and sterilization of water through a ozone generator that can be collected and recycled, and stable purification by adsorption of activated carbon.

In general, ozone generation in water treatment uses ozone generated through corona discharge. The ozone contact system applying ozone generated by the corona discharge is a method of using a diffuser or an injector to mix ozone-containing air in water and apply pressure to dissolve ozone in water.

However, in the method of generating ozone by such a corona discharge, it is difficult to select a pump for pressurizing ozone, which is a powerful oxidant, and the price is increased due to securing durability of the pump for pressurizing ozone or installing a device.

In addition, the above-mentioned corona discharge is not well mixed with water even if ozone is generated well, and because the ozone in the gaseous state flows out of the water in a bubble state, the concentration of ozone in water is relatively low. There is an inefficient aspect.

In addition, since the nitrogen component in the air is oxidized to generate nitrogen oxides during corona discharge, it pollutes the environment.

Accordingly, an object of the present invention for solving the above-mentioned problems is to propose a constant treatment system consisting of a coagulation tank, sedimentation tank, rotary filter, ozone generator, activated carbon adsorption tank, disinfection tank, etc., in the filtration of hydrocyclon Rotary filtration device that can separate particles by using vortex and vortex, as well as finally pass through filter media to separate heavy metals by contaminant separation and adsorption from water according to specific gravity and size of particles. To provide a constant treatment system using.

In addition, another object of the present invention to provide an ozone generating device by the electrolysis method in the ozone treatment, in particular, it is possible to freely adjust the ozone concentration according to the concentration of the pollution degree, which is generated by holding the raw water passed through the cathode electrode for a certain time It is to provide a water treatment system using an ozone generator that can collect and recycle H ₂ .

Accordingly, an object of the present invention is to provide an ozone generator on a water treatment system, comprising: a positive electrode for causing electrolysis; A negative electrode formed to face the positive electrode; An electrolyte membrane transferring hydrogen ions generated by electrolysis between the positive electrode and the negative electrode; It is achieved by the electrolytic ozone generating device, characterized in that consisting of; flow constant in which the introduced water is oxidized to generate ozone water.

In another aspect, the present invention provides a water treatment system, comprising: a flocculation tank for forming flocs through chemical treatment of a polymer flocculant in a constant flow from a raw water tank; A settling tank through which the precipitate of chemically treated constant water is precipitated in an easy state of precipitation through the flocculation tank; A rotary filtration device for filtering the purified water introduced from the settling tank and performing a filtration and adsorption process; An ozone generator for generating ozone water through a constant oxidation reaction through a rotary filtration device; Activated carbon adsorption for passing granular activated carbon to purify ozone water passing through the ozone generator; It is preferable that the chlorine sterilizer is configured to sterilize the adsorbed water through the activated carbon adsorption.

The water treatment system using the electrolytic ozone generator of the present invention configured as described above has the advantage of treating water by aggregation, precipitation, filtration, ozone water treatment, adsorption and disinfection,

By passing through the rotary filtration device in water treatment, the particles can be separated by using hydrocyclon and vortex, and finally passed through the filter medium to contaminate the effluent depending on the specific gravity and size of the particles. There is an advantage that can separate heavy metals by material separation and adsorption.

In the case of the ozone generator, the concentration of ozone water can be freely adjusted according to the concentration of pollution, and the H ₂ generated by retaining raw water passing through the cathode electrode for a predetermined time is collected and recycled. By recycling, there is an advantage that the treatment with more purified ozone water and the cleaning of the flow path are possible.

In addition, there is no need to install additional equipment, such as a blower and a micro-bubble device, thereby lowering the unit cost, and since there is no need for mixing ozone and water separately because electrostatic decomposition of the constant itself generates ozone water.

In addition, the only additional product in the generation of electrolytic ozone is harmless hydrogen, and as a secondary electrode, hydrogen ions generated from the anode are transferred to the cathode electrode to generate scale (by calcium and magnesium) on the surface of the anode electrode. This has the advantage of minimizing scale generation.

Hereinafter, the water treatment system using the electrolytic ozone generating apparatus of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a flow chart showing a schematic configuration of a water treatment system using an electrolytic ozone generating apparatus of the present invention, Figures 2a to 2c is an exploded perspective view, a side cross-sectional view, showing a rotary filtration device of one configuration of the present invention; 3 is a side sectional view showing a first embodiment of an ozone generating device of one configuration of the present invention, and FIG. 4 is a side sectional view showing a second embodiment of an ozone generating device of one configuration of the present invention. 5 is a side cross-sectional view showing a third embodiment of an ozone generator that is one configuration of the present invention.

As shown in the figure, the water treatment system using the electrolytic ozone generating apparatus of the present invention is a raw water tank 10, coagulation tank 20, sedimentation tank 30, rotary filter 100, electrolytic ozone generating device 200, the activated carbon adsorption tank 40, and the chlorine sterilizer 50.

The raw water tank 10 is a tank for storing a constant, the agglomeration tank 10 is a continuous mixture of fine contaminant particles or colloidal material in the constant by mixing a drug such as a polymer flocculant to the constant introduced from the raw water tank 10 Induces rapid mixing and is configured to form flocs through this chemical treatment process.

The coagulation tank 20 can take a long residence time of the constant therein and it is necessary to ensure a sufficient mixing time with the drug by lengthening the residence time, which is known in the coagulation tank 20 for this function Although not shown in the drawings as a technique, it is possible to construct a ditch wall or the like to increase the residence time of the constant to allow sufficient chemical treatment.

The sedimentation tank 30 is a water tank in which chemical treatment is precipitated in an easy-to-precipitate state through the agglomeration tank 20, and consists of two or more spaces in the sedimentation tank 20. It can be configured so that heavy particles are deposited by the immersion tank, and large particles are filtered out by the screen tank.

The constants filtered by the heavy particles and the large particles subjected to the chemical treatment can be filtered and adsorbed by passing through the rotary filtration device 100 to be described below.

2A to 2C, the rotary filtration device 100 includes a circulating chamber 110 through which inflow water flows, an inflow pipe 120 formed on one side of the circulating chamber 110, and the flow chamber 110. Sludge outlet portion 130 formed on the lower surface of the), the filtration chamber 140 formed on the top of the flow chamber 110, and the treated water outlet pipe 150 formed on one side of the filtration chamber 140 and And a chamber film 160 for partitioning the flow chamber 110 and the filtration chamber 140, and formed in the chamber film 160 to communicate with the flow chamber 110 in the flow chamber 110. It is composed of a circular membrane 170 in which the flowing inflow water flows in and flows into the filtration chamber 140.

When the components of the rotary filtration device 100 will be described in detail, the flow chamber 110 is cylindrical and flows therein as shown in FIG. 2B. The inlet pipe 120 is formed on one side of the flow chamber 110, it will be preferably configured in the tangential direction of the flow chamber 110. In this way, the inflow water to the inlet pipe 120 is allowed to flow in the circulating flow chamber 110 to generate hydrocyclon and vortex.

In addition, as shown in Figure 2b, the lower surface of the flow chamber 110 is preferably formed to be inclined gradient so that the diameter becomes narrower toward the center, which is a particle descending from the side wall of the flow chamber by the centrifugal force by the flow (S1 in Figure 2b) ) As well as to easily slide in the direction of the sludge outflow 130 to be described later, as the diameter decreases, the flow velocity increases as the diameter decreases, so that the vortex velocity increases toward the downward direction of the circulating chamber 110. This is to allow (S2 in Figure 2b) to easily flow out to the sludge outflow 130.

The sludge outlet 130 is formed at the center of the lower surface of the circulating chamber, which is also in the shape of an inverted cone which decreases in diameter in the downward direction. As shown in FIG. The central core (C) is to hold the role.

The filtration chamber 140 is configured in a cylindrical shape, but may be configured in a separate space by being configured on the circulating chamber 110, but may be configured in one piece in FIGS. 2A and 2B, but the chamber membrane 160 will be described below. Divided by. Inside the filtration chamber 140 is a circular membrane 170 which is in communication with the flow chamber 110, the inflow water flowing in the flow chamber 110 flows into the filtration chamber 140 can be overflowed The filter medium 180 is filled between the outer periphery of the circular membrane 170 and the inner periphery of the filtration chamber 140.

The filter medium 180 may be filled with a combination of various media such as sand, gravel, activated carbon, zeolite, and the like in which one or more media are filled. As the filter material 180 is filled in this way, heavy metals and the like contained in the discharge water flowing over the circular membrane 170 may be finally absorbed and flow out through the treated water outlet pipe 150 to be described below.

The chamber membrane 160 is formed by partitioning the filtration chamber 140 and the flow chamber 110. The circular membrane 170 is formed at the center of the chamber membrane 160 to form the circular membrane 170. And the flow chamber 110 is configured to communicate with each other. The chamber film 160 is preferably configured as a conical shape in which an upward inclination gradient is formed in the center direction, that is, the direction in which the circular film is formed. In this way, the treated water having passed through the filter medium 180 is easily discharged to the treated water outlet pipe 150 by the chamber membrane 160. In the flow chamber 110, the conical chamber membrane 160 is formed. The diameter becomes smaller toward the upward direction, and the speed of the return flow is faster due to this shape, the faster the flow rate of the inflow water in the inner periphery of the circular membrane 170, the faster the treatment speed of the influent.

The treatment water outlet pipe 150 is configured at one side of the filtration chamber 140, and the treatment water filtered and adsorbed to the outside is discharged to the outside and the bottom of the chamber membrane 160 and the bottom surface of the treatment water outlet pipe 150. It is preferable that the treatment water is configured to be easily discharged to the outside through the treatment water outlet pipe 150 by riding the inclined surface of the chamber membrane 160.

Hereinafter, the operating state of the rotary filtration device 100 will be described.

As shown in FIG. 2C, the inflow pipe 120 is configured in the tangential direction of the flow chamber 110 so that water obtained through the inflow pipe 120 naturally forms a flow without any power. As shown in FIG. 2B, the movement path of the particles S1 having a larger specific gravity than the water due to such a flow moves to the side wall of the flow chamber 110 by centrifugal force and rides on the bottom surface of the flow chamber 110. Out).

This flow generates a vortex and at the center of the vortex generates a portion of the core (C) that rotates at a speed more than twice the tangential flow rate, the core (C) is the sludge outflow from the upper surface of the circular membrane 170 It is a part that generates a strong suction force in the downward direction as a cavity sphere connected up to (130). Therefore, in the case of the movement path of the particles S2 whose specific gravity is smaller than the water, the particles move toward the water surface by moving to the center by the centripetal force as opposed to the movement path of the particles S1 having the specific gravity larger than the water. The sludge outflow portion 130 is discharged by the direction suction force.

In addition, the moving path of the particles (including heavy metals, etc.) S3 having a specific gravity similar to that of water moves along with the flow of water, and flows through the circular membrane 170 and flows into the filtration chamber 140 to filter the material according to the flow of water. While passing through 180, the heavy metal is finally filtered through adsorption.

As shown in the above, the rotary filtration device 100 separates particles from water by centrifugal force and gravity caused by hydrocyclon, and the specific gravity is smaller than water when the specific gravity of the particles is greater than water through non-powered flow. Particles are separated from water using centripetal force and downward suction force by vortex.In the case of particles (including heavy metals) that move with water due to specific gravity similar to water, particles are separated from water through filter media. It is.

The constant passed through the rotary filtration device 100 generates ozone water for oxidation reaction by the ozone generator 200 to be described below.

With respect to the ozone generator 200, the present invention proposes three embodiments, hereinafter, the respective configurations will be described.

First, in the ozone generator 200, the first embodiment 200a includes a positive electrode 210 for causing electrolysis, as shown in FIG. 3, in one housing h1. The positive electrode 210 is configured to generate oxygen (O 2), hydrogen ions (H ■), and ozone (O 3), and the negative electrode 220 is formed on the other housing h 2. ) Produces hydrogen (H₂) and OH ■. In addition, an electrolyte membrane 230 is formed between the positive electrode 210 and the negative electrode 220, wherein the electrolyte membrane 230 is formed of hydrogen ions (H ■) generated by the positive electrode 210 by an electrolysis reaction. It is the function that is delivered. The positive electrode 210 and the negative electrode 220 may be made of a material such as platinum suitable for ozone generation.

Between the positive electrode 210 and the electrolyte membrane 230, and between the negative electrode 220 and the electrolyte membrane 230, a flow path 240a of a network structure is formed, respectively, and the flow of raw water is performed by the negative electrode 220 and the electrolyte. It passes through the network flow path 240a (the network flow path 240a of the negative electrode 220 side) between the membranes 230, and in the network flow path 240a of the negative electrode 220 side. Raw water is introduced into the raw water inlet 241a formed at one end, and the raw water is discharged to the raw water discharge unit 242a formed at the other end. The discharged raw water is formed between the positive electrode 210 and the electrolyte membrane 230. In the flow path 240a of the structure (the network flow path 240a on the positive electrode 210 side), the ozone water is re-flowed through the raw water circulation inlet portion 243a formed at one end and oxidized to generate ozone water. It is discharged to the ozone water discharge portion 244a formed at the lower end thereof and flows out to the activated carbon adsorption tank 30 to be described below.

The flow path 240a of the network structure causes turbulence and vortex flow in the discharge water passing therethrough due to the network structure, so that the flow rate is increased by this flow, so that ozone dissolution occurs efficiently.

On the other hand, in this embodiment, the auxiliary electrode 250 is formed on the surface of the negative electrode 220 in contact with the flow path 240a of the network structure, the auxiliary electrode 250 is generated from the positive electrode 210 Electrolysis is performed by transferring hydrogen ions to the negative electrode 220 and preventing the generation of scale at the negative electrode 220 by forming a scale generated on the surface of OH ■ generated in the negative electrode 220 by reaction with the metal ions of the cation. Make the reaction smooth.

In addition, in the present embodiment, as shown in FIG. 3, the pressurizing means 270a is formed on the outer surfaces of the positive electrode 210 and the negative electrode 220, that is, the positive electrode 210 and the inside of the housing h1 and the negative electrode. The pressing means 270a is configured in the 220 and the housing h2, respectively. The positive electrode 210 and the negative electrode 220 are pressurized by the pressing means 270a, and the positive electrode 210 and the negative electrode 220 are electrostatically charged by the pressing means 270a. In the direction in which it is formed) and configured to be able to slide later (in the respective housing (h1, 2) directions). By pressing the electrodes 210 and 220, in particular the positive electrode 210, by the pressing means 270a, the width d1 formed by the flow path 240a of the network structure is reduced. When the width d1 formed by the flow path 240a of the decreases, the flow rate of the effluent flowing therethrough increases, and the increase of the flow rate increases the dissolution rate of ozone, thereby increasing the ozone water concentration through the ozone water discharge part 244a. Can be discharged. However, when the flow rate of the effluent water is accelerated by the pressurization, the fatigue of the electrolyte membrane 230 is increased, and the increase of the fatigue may shorten the life of the electrolyte membrane 230, so the contamination of the effluent and the use of the treated water are used. By releasing the pressurization of the pressurizing means 270a, etc., the fatigue of the electrolyte membrane 230 can be reduced.

Meanwhile, in the ozone generator 200, the second embodiment 200b is configured such that the positive electrode 210 and the negative electrode 220 contact each other with the electrolyte membrane 230 interposed therebetween as shown in FIG. 4. The auxiliary electrode 250 is inserted between the film 230 and the negative electrode 220. The positive electrode 210 and the negative electrode 220 are formed outside the flow path 240b of the network structure. The flow path 240b of the network structure includes a pressure plate 271b mounted to one housing h1. Between the positive electrode 210 and between the pressure plate (271b) and the negative electrode 220 which is mounted on the other housing (h2), the raw water inlet for the raw water flow in the case of the flow path 240b of the network structure ( 241b), raw water discharge part 242b, raw water circulation inlet part 243b, and ozone water discharge part 244b. That is, as shown in FIG. 4, the flow path 240b of the network structure formed between the pressure plate 271b mounted on the lower housing h2 and the negative electrode 220 (the flow path of the network structure of the negative electrode 220 side) 240b)) raw water is introduced into and discharged from both ends of the raw water inlet 241b and the raw water discharge unit 242b, and the discharged raw water is pressurized plate 271b and the positive electrode mounted on the upper side housing h1. Raw water is passed through the raw water circulation inlet 243b and the ozone water discharge unit 244b at both ends of the network flow path 240b (the network flow path 240b on the positive electrode 110 side) formed between the 210. The water is circulated, oxidized to generate ozone water, and the generated ozone water flows out into the activated carbon adsorption tank 30 to be described below.

The positive electrode 210, the negative electrode 220, and the auxiliary electrode 250 have the same function and material as those of the first embodiment, and a description thereof will be omitted, and the first embodiment of the flow path 240b of the network structure will also be omitted. Since it has the same function and material as the network flow path 240a in the example, the description is abbreviate | omitted.

In addition, in the present embodiment, as shown in FIG. 4, the pressing means 270b is formed on the outer surface of each pressing plate 271b, that is, the pressing plate 271b and the housing h1 and the pressing plate 271b and Pressing means 270b are configured in the housing h2, respectively. In the case of the pressing means 270b, each pressing plate 271b is configured to be slid to the front (the direction in which the electrolyte membrane 240 is formed) and to the rear (the respective housing (h1, 2) directions). The width d2 of the flow path 240b of the network structure is reduced by this, and the dissolution rate of ozone can be increased by decreasing the width d2 of the flow path 240b of the network structure. . In addition, it is possible to reduce the fatigue of the electrolyte membrane 230 by the pressure release. In the case of the present embodiment 200b, the pressurizing means 270b presses the pressure plate 271b without directly pressing the positive electrode 210 and the negative electrode 220 in comparison with the first embodiment 200a. As it is performed by directly pressing the positive electrode 210, the negative electrode 220 will be able to remove the elements that interfere with the electrolysis reaction, such as disturbance of the current in the electrode.

Meanwhile, as shown in FIGS. 3 and 4, the first embodiment 200a and the second embodiment 200b respectively include raw water passing through the flow paths 240a and b of the network structure on the negative electrode 220 side, respectively. Hydrogen collecting device 290 to allow the raw water to be retained for a predetermined time before circulating to the flow paths 240a and b of the network structure on the 210 side to collect and recycle the hydrogen gas generated on the negative electrode 220 side. ) May be further configured. The hydrogen collecting device 290 is configured to communicate with each of the raw water discharge portion (242a, b) and the raw water circulation inlet (243a, b), the raw water discharged to each of the raw water discharge portion (242a, b) is hydrogen collection Hydrogen is extracted while being stored in the apparatus 290, and the raw water from which the hydrogen is extracted is configured to flow through each raw water circulation inlet 243a, b. The hydrogen collecting device 290 is not shown in the drawings, but the raw water circulating inlet unit 243a and b receives the raw water introduced based on the time when the raw water is introduced or the amount of hydrogen collected by the control of the controller. It would be desirable to be configured to allow for discharge. The hydrogen collecting device 290 is a device for extracting dissolved hydrogen from the stored water can be recycled for various uses.

Meanwhile, as shown in FIGS. 3 and 4, the first embodiment 200a and the second embodiment 200b are treated with ozone water to reprocess ozone water discharged through the respective ozone water discharge units 244a and b. The circulation line 280 may be further configured. By recycling through this circulation line, the foreign matter deposited in the network of the network flow paths 240a and b can be naturally cleaned through the recycling process, and the purified water can be generated by repeating the ozone treatment. It will be possible.

In addition, the circulation line 280 should be configured to enable artificial recycling by configuring the pump 281.

In addition, a third embodiment 200c is shown in FIGS. 5A and 5B as another embodiment of the present invention, and FIGS. 5A and 5B illustrate a positive electrode 210, a negative electrode 220, and a network flow path 240a. Although the structure of the present invention is based on the first embodiment, the present embodiment may be applied based on the second embodiment.

First, the third embodiment 200c differs from the first and second embodiments in that the polarity conversion device 260 is configured as shown in FIGS. 5A and 5B so that the electrode is configured as a variable electrode. .

That is, in FIG. 5A, the upper electrode is the positive electrode 210, and the lower electrode is the negative electrode 220, and ozone water is discharged through the network flow path 244a on the positive electrode 210 side.

In this continuous electrolysis process, since the scale generated by OH ■ generated in the negative electrode 220 reacts with the metal ions of the cation is deposited on the surface of the negative electrode 220, the deposition of such scale is an electrolysis reaction. Will be inhibited. Therefore, the production of ozone water is also hindered. Therefore, in this case, as shown in FIG. 5B, the upper electrode is converted into the negative electrode 220 using the polarity converting device 260, and the lower electrode is changed into the positive electrode 210.

Therefore, although not shown in the drawings, it is natural that the inlet of the raw water and the discharge of the ozone water should be converted according to the polar change of the electrode by the action of the polarity conversion device 260 by configuring the control valve.

On the other hand, the polarity conversion device 260 may be configured to be available as a current voltage conversion device for other uses. When the polarity converting device 260 is available as a current voltage converting device, regeneration of the electrolyte membrane can be performed by converting only the current and the voltage with the polarity of each electrode as it is.

The ozone water oxidized through the electrolytic ozone generator 200 is introduced into the activated carbon adsorption tank 40.

The activated carbon adsorption tank 40 is a device for filtering and purifying ozone-treated ozone water. Particularly, the granular activated carbon used therein is activated carbon made of coconut shell, charcoal, coal, and the like. The activated carbon is usually filled with activated carbon having a particle size of 8 ~ 30 mesh and mainly uses a downflow tower.

The chlorine sterilizer 50 uses chlorine having excellent sterilizing power to react a portion of the chlorine water with water to generate residual chlorine (HClO), thereby disinfecting the water by the strong oxidation of generator oxygen produced while the residual chlorine is decomposed. Do it.

Thus, the filtration, sterilization, sterilized water through the chlorine sterilizer 50 is introduced into each water pipe is supplied to the living water.
