High Density Plasma Method and its Device Coupled with Ultrasonic Wave for Waste Water Treatment

The present invention relates to a wastewater treatment method using ultrasonic and high-density plasma, and to a device thereof. Specifically, the present invention relates to radical wastes in industrial wastewater such as dyeing wastewater, leather wastewater, petrochemical wastewater, and papermaking wastewater, and various wastewater such as livestock wastewater and domestic wastewater. Micro-mixing to the molecular level that vibrates violently with ultrasonic waves of 20,000Hz to 40,000Hz while bubbling negative ions and ozone containing electrons and electrons.High density anions are dissolved in the wastewater and hydrated organic or heavy metal complexes. Ions (complexions), radicals, electrons, and anions leave the hydration seath, allowing organics and complex ions to be released in water as if volatile organic matter (VOCs) are rapidly oxidized by anions in the air. It is quickly oxidized and decomposed to be cleansed.

Wastewater containing various pollutants is high in color, contaminating water quality such as river, groundwater and seawater, and blocking water and oxygen coming into the water, causing enormous damage to aquatic organisms and microorganisms. Edo has become a major obstacle.

In addition, the amount of industrial wastewater is increasing rapidly according to the increase of population and industrial development, and the environmental pollution and the destruction of ecosystem caused by these are emerging as a big social problem. The treatment methods and methods are being studied with a lot of hard work.

In the past, various methods of wastewater purifying devices, such as pH adjustment, coagulation of contaminants, and treatment by microorganisms, have been proposed. And it is difficult to purify and remove by the aggregate in reality, there is a problem that the purification efficiency is very low and the treatment cost is increased.

In addition, it is possible to purify and treat high-purity raw water with relatively low chemical oxygen demand (COD), such as first-class or second-class water, with ozone. It is almost impossible to purify high concentration industrial wastewater such as sugar wastewater with ozone.

Therefore, the present invention is capable of bubbling anions and ozone containing radicals and electrons into various industrial wastewaters such as dyeing wastewater, leather wastewater, petrochemical wastewater, and papermaking wastewater, and livestock wastewater and domestic wastewater, while 20,000 Hz to 40,000 Hz. Micro-mixing to the molecular level that vibrates violently with ultrasonic waves of organic matter, wastes, organics, heavy metal complexes, radicals, electrons, and anions leave the hydration seath. It is an object of the present invention to provide a wastewater treatment method in which volatile organic compounds (VOCs) are rapidly oxidized and decomposed by anions, thereby rapidly oxidizing and decomposing organic substances or complex ions in water and purifying them cleanly.

It is also an object of the present invention to provide a wastewater treatment apparatus suitable for the wastewater treatment method. In general, plasma generated by high voltage low current direct current discharge in air is composed of ions, radicals, and electrons. In this case, the corona discharge mainly generates anions such as oxygen anions (O ₂ ⁻ ), ozone anions (O ₃ ⁻ ), hardoxide radicals (OH ·), radicals and electrons, and thus, plasma generators are called anion generators. In addition, since the ozone (O ₃ ) is mainly generated in the spark discharge, the plasma generator is called an ozone generator.

On the other hand, bubbling air, oxygen, or ozone or a mixture of these gases while electrolyzing (electrolyzing) the industrial wastewater causes chromaticity, chemical oxygen demand (COD), biological oxygen demand (BOD) and dispersion of the industrial wastewater. ^{oxidation-solid} (SS) to lower significantly the particle, etc., and the industrial waste water purification process, the compound or into a mixture thereof in industrial waste when the ring of air and oxygen, and ozone or a mixture of these gas bubbles chloride ion (Cl) due to the hypochlorous acid ions (ClO ₂ ^-), chlorite ion (ClO ₂ ^-), chlorate ion (ClO ₃ ^-) and the hypochlorite ion (ClO ₄ ^-), because the generation is greatly increased solubility of oxygen in the waste water.

Also, By this electrolysis the waste water including the same chlorate ion oxygen ions with high energy from these chlorite ion (O ₂ ^-) are to come separately attack the chromophore or auxochrome of the dye molecules or pigment molecules oxidation of these molecules Degradation reduces the chromaticity, COD, BOD, SS, etc. of the wastewater and cleanses it.

In general, it is possible to highly purify and treat tap water with relatively low chemical oxygen demand (COD), such as first-class or second-class water with ozone. It is almost impossible to purify high concentration industrial wastewater such as sugar wastewater with ozone.

However, micro-mixing at a semi-molecular level using ultrasonic waves ranging from 20,000 Hz to 40,000 Hz while bubbling anions or ozone containing radicals and electrons into the wastewater, the organic or heavy metal complex ions dissolved and dissolved in the wastewater Complex ions, radicals, electrons, and negative ions leave the hydration seath. Therefore, organic matter or complex ions are rapidly oxidatively decomposed in water as if volatile organic matter (VOC) is rapidly oxidatively decomposed by anions in the air.

This is due to the fact that high frequency ultrasonic waves can cause gas-like reactions in water due to the destruction of the hydration layer as mentioned above, while at the same time bringing the organics, complex ions, anions and electrons in the water to a higher energy state. It is possible because it is activated.

Under these conditions, both the positive electrode and the negative electrode are inert carbon electrodes, and electrolysis is performed by changing the polarity at regular intervals, and the present invention devises a method for treating the continuous electrolytic purification of wastewater and its apparatus (Patent 10-0188232). The waste water can be purified more quickly.

In this case, the polarity of the electrode is periodically changed to increase the efficiency of electrolytic purification by removing the dispersion sludge in the water that adheres to the anode to prevent overvoltage generated at the anode.

Such wastewater treatment is the most suitable and economical method for advanced wastewater purification because it has a special effect on denitrification, dephosphorization, decolorization and deodorization as well as chemical oxygen demand (COD), biological oxygen demand (BOD), and sludge removal. In particular, this wastewater treatment device equipped with an electrolytic device has a very high color removal effect of the high color dye wastewater.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is composed of a decomposing tank (2) in which wastewater is fresh water, and a reactor (6) for circulating and treating the wastewater (4) of the decomposing tank (2), wherein the reactor (6) purifies the wastewater (4). A reaction chamber to be treated, an auxiliary reaction chamber, a circulator for circulating the waste water 4 into the decomposition tank 2 and a reaction chamber, an ultrasonic vibrator for vibrating the waste water 4 ultrasonically, and anion and ozone into the waste water 4 It consists of an anion and ozone generator which dissolves and purifies, and an electrolytic apparatus.

1 is a cross-sectional configuration of the present invention, the decomposing tank (2) in which the wastewater (4) is fresh water is composed of a concrete structure or steel structure of a suitable size according to the treatment capacity, having a valve on both sides of the decomposing tank (2) A wastewater feedwater pipe 10 having a wastewater feedwater pipe 8 and a valve is provided.

Reactor (6) is installed in a semi-submersible in the digestion tank (2) using a pair of trivets (3) (3a) as shown in FIG. 1 or installed on the outer side of the digestion tank (2) as shown in FIG. , The case 12 of the reactor 6 composed of a cylindrical or polygonal shape is formed of a metal material having corrosion resistance and chemical resistance to have durability.

In the case where the reactor 6 is installed in a semi-submersible manner using the trivets 3 and 3a, the distal end of the water supply pipe 8 and the distal end of the discharge pipe 10 are about 10 cm from the bottom of the dissolution tank 2. Spaced apart to prevent mechanical shock, and by lowering the center of gravity of the reactor (6) or by using a fastening means to the trivet (3) (3a) to prevent rotation or flow of the reactor (6).

In addition, when the reactor 6 is installed outside the digestion tank 2 as shown in FIG. 2, a removable scraper is installed on the upper portion of the digestion tank 2 to remove sludge.

On both sides of the reaction chamber 14 of the reactor 6, the inlet pipe 16 into which the wastewater 4 to be treated is introduced and the discharge pipe 18 through which the purified wastewater 4 is discharged are immersed in the decomposition tank 2, It is installed to be connected, and both sides of the reactor 6 and the reaction chamber 12 is formed to gradually narrow toward the inlet pipe 16 and the outlet pipe 18.

The inlet tube 16 and the outlet tube 18 are formed of a synthetic resin such as nylon rather than a metal tube to prevent the destruction of negative ions or shorten the life, and the inlet tube 16 has an air stone filter 20 and a pump 22. ), The wastewater 4 of the digestion tank 2 is filtered and then introduced into the reaction chamber 14 by the pump 22 for purification, and the purified wastewater 4 is transferred to the digestion tank 2. The discharge process is repeated and circulated, and the inlet portion of the reaction chamber 12 fixes a plurality of inclined plates 22 so that the incoming wastewater 4 vortex vortex (quasi-aeration state) to make an effective reaction. To lose.

A secondary reaction chamber 26 having a smaller size than the reaction chamber 12 is formed between the outlet 24 and the outlet pipe 16 of the reactor 6 that gradually narrows to allow the high density of anions to stay for a while. The wastewater 4 purified in (14) is moved to the auxiliary reaction chamber 26 so that it can be sufficiently purified by another reaction.

Since the size of the outlet 24 is narrower than that of the auxiliary reaction chamber 26, the wastewater 4 flowing from the reaction chamber 14 is vortexed and aerated, and the cross-sectional shape of the case 12 of the reactor 6 is aerated. Although it may be a cylindrical shape if it can be fixed without the loss of ultrasonic waves, it is preferable to form a polygonal structure before and after the octagonal shape so as to be fixed in close contact with the ultrasonic vibrator 28 as shown in FIG.

Fixing a plurality of ultrasonic vibrator 28, which generates 20,000Hz ~ 40,000Hz ultrasonic waves for each outer surface of the polygonal case 12, and then cover the protective case 30 to form an ultrasonic band 32, ultrasonic band 32 In consideration of the length and size of the reactor (6) is to be installed in a plurality of two or more.

Since the ultrasonic vibrator 24 is focused on the ultrasonic wave toward the center point O of the reaction chamber 14 by the polygonal case 12 structure as shown in FIG. 3, the density increases and the vibration effect is amplified toward the center, 20,000 Hz. The waste water 4 vibrates violently by quasi-molecular state by ˜40,000 Hz ultrasonic waves.

Therefore, organic matter, heavy metal complexes and radicals, electrons, and anions dissolved and hydrated in the wastewater 4 escape from the hydration seath, and the volatile organic matter (VOC) in the air As the organic matter and complex ions in the wastewater 4 are rapidly oxidized and decomposed as in the case of oxidative decomposition, the wastewater 4 is purified cleanly.

On the other hand, the high density plasma generator 34 is installed on the case 12 of the reactor 6 so that a large amount of anions and a small amount of ozone are dissolved into the waste water 4 so that the waste water 4 can be effectively purified.

An inlet portion of the high-density plasma generator 34 is provided with an air supply pipe 36 as shown in FIG. 1, and an air supply fan 38 capable of adjusting the air supply amount for blowing air at 2 to 5 atmospheres in the air supply pipe 36. ), A check valve 40 to prevent backflow of air, and an electrostatic precipitating or biodusting filter 42 which prevents the inflow of impurities, and the filtered air is supplied without backflow, and thus high density of anions and a small amount of ozone are provided. Is generated and dissolved in the waste water 4.

The high-density plasma generator 34 is installed somewhat higher from the constant surface of the wastewater 4 to maintain insulation.

4 is a cross-sectional configuration diagram of the high-density plasma generator 34, in which a housing 48 having a catching portion 44 and a large diameter vent hole 46 is inserted into and fixed to a case 12, and the housing 48 is fixed. A plurality of ceramic insulating rings 50, 52, 54, 56 are laminated in the inside of the cover, and then covered with a cover ring 60, and fixed, and a plurality of cathode tubes 72 at the stepped portions of the lower insulating ring 52. The negative electrode plate 62 to be fastened is installed, and a plurality of vent holes 64 are formed in the stepped portion of the insulating ring 56, and the positive electrode plate 66 to which the positive electrode rods 74 are fastened. The positive electrode plate 66 and the negative electrode plate 62 maintain the spacing and insulation in the housing 48.

A cathode rod 62 and a cathode plate 66 are connected to a feed line 68 and 70 to which a high voltage portion HV is connected, and an anode rod having an outer diameter relatively smaller than an inner diameter of the cathode tube 72 inside the cathode tube 72. 74), but the anode rod 74 and the cathode tube 72 is spaced apart so as not to contact each other to form a ventilation hole therebetween, the high voltage portion (HV) is a commercial power supply voltage of 3,000V ~ 25,000V After boosting with a current of several A at several μA and then supplying to the positive electrode plate 66 and the negative electrode plate 62, plasma P by corona discharge is generated.

On the other hand, the end of the anode rod 74 is to form a needle-shaped plasma discharge chip 78 with a sharp tip as shown in Figure 5, the lower portion of the cathode tube 72 where the discharge chip 78 is located 5, 6 as shown in Figure 6 formed a plurality of discharge holes in a narrow interval, and the lower end of the cathode tube 72 protrudes slightly downward than the anode rod 74 to form a discharge hole (80a) located in the center portion Corona discharge is generated up and down at the center to obtain a high density plasma (P) and a high density (large amount) of anions and a small amount of ozone (O ₃ ) caused by the action of the plasma.

In this case, the efficiency is improved by 30% or more compared with the conventional method. The discharge hole 80 may be installed in the cathode tube 72 as a whole, but since the concentration of charge may be dispersed and discharge efficiency may be reduced, the discharge hole 80 may be installed around the discharge chip 78 where the discharge charge is concentrated. do.

In addition, since the discharge portion 82 of the discharge hole 80 has a corner structure forming an angle of about 90 °, the discharge charges are also concentrated, and thus the corona discharge efficiency is maximized and accordingly, the plasma of high density is high. (P) is generated and is discharged as air is anionized and ozoneized by the action of plasma.

In the above, a strong corona discharge and aeration of the wastewater 4 are made by the pressurized air of 2 to 5 atm, and the discharge chip 78 having a sharp end portion has a short life due to precipitation (elution) and abrasion. Since the plasma discharge chip 78 may be formed of a conductive anti-oxidation material or coated on the surface thereof to form an oxide film, the life of the plasma discharge chip 78 may be extended.

In addition, even if discharge heat is generated by corona discharge, a large amount of air is supplied to the vent holes 46, 64, 76 by an air pressure source (not shown), thereby preventing overheating of the anode rod 74 and the cathode tube 72. In addition, since an air pressure difference is generated between the inside and the outside of the cathode tube 72 due to the flow rate of the air flowing through the vent hole 76, the air located outside the anode rod 74 passes through the discharge hole 80. Since it is introduced into the inside of the anode rod 74 and the cathode tube 72 is made of heat radiation.

7 is an exploded perspective view showing another embodiment of the electrode used in the high-density plasma generator 34, in the longitudinal direction of the pyramid (square pyramid) -shaped discharge chip 84 on the outer surface of the anode rod 74 at a tight interval And circumferentially and circumferentially, the discharge holes 86 are formed in the cathode tube 72 at a position corresponding to the discharge chip 84 in a 1: 1 manner so that corona discharge is generated entirely.

The materials of the anode rod 74, the cathode tube 72, the anode plate 66, the cathode plate 62, and the discharge chips 78 and 84 are heat resistant, such as molybdenum, tungsten, nickel, platinum or nickel, molybdenum, copper, and the like. And the anode plate 74 and the cathode plate 62 to which the anode rod 74 and the cathode tube 72 are fixed, and are formed of the same material as above. The thermal expansion coefficient should be the same while the resistance is excellent.

The high-density plasma generator 34 may be installed in one or more, as shown in Figure 8 depending on the processing capacity and the size of the reaction chamber (14).

On the other hand, the high density plasma generator 34 prevents the backflow of the wastewater in the reaction chamber 14 by the check valve 40, but the anode rod 74 and the cathode tube 72 are electrically shorted by evaporated water and moisture. The dehumidifier 88 of the same type as shown in FIG. 9 may be installed.

That is, the electric heat heater 90 in which insulation is maintained is wound around the outer surface of the case 12 at the portion where the anode rod 74 and the cathode tube 72 are positioned, and the temperature switch 92 is placed on the surface of the case 12. After installation, the high density plasma generator 34 can be heated to 150 ° C. to 300 ° C. when the high density plasma generator 34 is initially operated by serially connecting the electrothermal heater 90 powered by an unillustrated switch. By removing the evaporated water and moisture penetrated or penetrated between the anode rod 74 and the cathode tube 72 to prevent electrical short circuit or failure of the high-density plasma generator 34, the heat transfer heater 90 and the temperature switch 92 is wrapped around the case 94 to protect.

10 is a cross-sectional view of another embodiment of the present invention, in which an anion and ozone generated by the high-density plasma generator 34 is formed by installing an isolation tank 96 having a cylindrical or polygonal structure inside the reaction chamber 14. By dissolving with the waste water in the) portion it can effectively prevent the electrical short circuit of the high-density plasma generator 34, wherein the ultrasonic band 32 is preferably installed on the outer surface of the isolation tank (96).

In the present invention, a flange structure is connected between the case 12 and the case 12, the case 12, and the high-density plasma generator 34 so that repair, movement, and assembly can be disassembled and assembled, and the reaction chamber 14 Drain valves (98) and (100) at the bottom of the auxiliary reaction chamber (26) to be used when depositing or cleaning.

In the above, both the anode 104 and the cathode 106 are inert carbon electrodes, and a polarity alternating device 108 is installed in the middle of a feeder line. The wastewater can be purified more quickly than the electrolytic purification treatment method and its apparatus (Patent No. 10-0188232).

At this time, periodically changing the polarity of the electrodes 104 and 106 using the polarity alternating device 108 in a period of 2 to 10 minutes removes the sludge in the water that adheres to the anode 104 and at the anode 104. This is to increase the electrolytic purification treatment efficiency by preventing the generated overvoltage, and in this case, the phenomenon that the sludge adheres to the electrodes 104 and 106 even by ultrasonic waves is significantly suppressed.

In the present invention, the sludge removal apparatus having the scraper 126 is provided in the preliminary digestion tank 58 and the coagulation tank (sedimentation tank) 202 in FIGS. 15 and 16.

Therefore, in order to effectively remove the sludge or foam using the scraper 126, the water level control must be accurate.

Therefore, the preliminary digestion tank 58 and the coagulation tank are installed in the bend-type drain pipes 212 and 218 of the preliminary digestion tank 58 and the coagulation tank (sedimentation tank 202) as shown in FIG. It is possible to accurately adjust the level of the (precipitator: 202) according to the state and height of the sludge.

As for the water level control device 220, the drain pipe 224 opened upward to the outlet 222 of the preliminary digestion tank 58 and the coagulation tank (sedimentation tank: 202) as shown in FIG. At the outside of the water collector is installed in the water collecting pipe 226 which is raised more than the drain pipe 224, the primary decomposition tank 2 and the pH reservoir 210 in one lower portion of the water collecting pipe 226 open to the upper side The condensate outlet pipes 212 and 218 are connected.

19 is a wastewater treatment flow chart of the present invention ultrasonically coupled high density plasma wastewater treatment apparatus. Here, the preliminary decomposition tank is attached with an ozone generator, an ultrasonic generator and a scraper 126.

In this preliminary decomposition tank, as mentioned above, organic compounds, heavy metal complex ions and ozone molecules dissolved in the waste water by ultrasonic are removed from the hydration layer and activated at a high energy state. Thus, organic molecules and complex ion oxidation by ozone are activated. Due to the large decomposition effect, COD, BOD, SS, TN, TP reduction rate of landfill leachate and high concentration livestock wastewater is good and decolorization and deodorization effect is very high.

Since the sludge is removed by the scraper 126, the reduction rate of SS generated by the aggregation of the preceding molecular decomposition residues is also large. The primary digester has the same effect as the preliminary digester because it is attached with an anion generator and an ultrasonic generator, but the only difference is that the anion including radicals oxidize and decompose organic matter and complex ions in the wastewater.

Unlike the preliminary digestion tank, sludge produced in the primary digestion tank is coagulated or precipitated with an inorganic flocculant such as aluminum sulfate, ferric chloride, PAC, or an ionic organic flocculant. The secondary digester has the same structure as the primary digester. Therefore, the function is the same as that of the primary digestion tank, but the purpose of increasing the wastewater treatment efficiency by repeating the same decomposition process once more.

During the first and second digestion tanks, 70% to 90% or more of phenol, its derivatives, and heavy metal ions, which are extremely harmful to microorganisms contained in high concentration leachate or livestock wastewater, are removed, thus removing acids and alkalis such as hydrochloric acid and caustic soda. The pH is adjusted to 7-8 in the pH control tank to be injected, and then the high-density microbial reaction tank in which high-density microorganisms are grafted to the high-porous media shows 95% or more purification effect.

Chemicals used in the primary sedimentation tank (agglomeration tank) are added to the treated water after the high density microbial reaction tank, and the precipitate is adsorbed and treated in the activated carbon adsorption tank. Next, the hollow fiber membrane filter or the RO (reverse osmosis) ultrafiltration Through this process, the ultimate purpose of wastewater treatment can be treated and reused, and so-called non-discharge wastewater treatment, which only replenishes evaporated or lost amounts of water and does not discharge the wastewater treatment at all, becomes possible.

FIG. 20 omits the secondary decomposition tank in the flow chart of FIG. 19 and replaces the high-density microbial reactor with the general microbial reactor, to discharge the treated water passing through the activated carbon adsorption tank. In this case, the water quality of the discharged water is very good and it becomes colorless, odorless and denitrification (denitrification) and discharged water with dephosphorization degree of 95% or more.

The present invention is the most effective physicochemical wastewater treatment device to date in the pre-treatment of high-density microbial treatment and general microbial treatment in Fig. 19 and 20, the test results are shown in Table 1 below. Unit: mg / l) Category Item COD BOD SS (Total nitrogen) TN (Total-in) TP enemy 9,875.0 7,520.8 23,505.0 2,475.0 185.2 Pre-decomposition water 977.6 3,008.3 1,104.7 1,064.3 9.4 Removal rate (%) 90.1 60.0 95.3 57.0 94.9 1st decomposition water 404.9 473.8 517.1 740.0 4.1 Removal rate (%) 95.9 93.7 97.8 70.1 97.8 Secondary decomposition treatment water 167.9 293.3 117.5 49.1 0.9 Removal rate (%) 98.3 96.1 99.5 80.2 99.5 As shown in Table 1, the removal rate after preliminary treatment of leachate having COD = 9,875.0ppm, BOD = 7,520.8ppm, SS = 23,505.0ppm, TN = 2,475.0ppm, TP = 185.2ppm was COD = 90.1%, BOD = 60.0% , SS = 95.3%, TN = 57.0%, TP = 94.9%. However, except for the 70.1% TN removal rate, the primary decomposed water ranged from 93.7% to 97.8%. However, except for TN = 80.2%, the removal rate of secondary cracked treated water exceeds 96%. TN = 80.2% is the highest removal rate of all wastewater treatments to date. Here we demonstrate the advantages and superiority of the ultrasonically coupled high density plasma wastewater treatment method. In addition, the device has the advantage of being very simple to operate and unaffected by seasonal temperatures.

On the other hand, while mixing the anion and ozone containing radicals and electrons generated from the high density plasma generator 34 into the wastewater, using the ultrasonic wave of 20,000Hz to 40,000Hz, micromixing the wastewater 4 to a molecular level. (Micro mixing) leaves organic and heavy metal complex ions, radicals, electrons, and anions hydrated in the waste water out of the hydration seath.

Therefore, organic matter or complex ions are rapidly oxidatively decomposed in water as if volatile organic matter (VOC) is rapidly oxidatively decomposed by anions in the air. This is due to the fact that high frequency ultrasonic waves cause gas-like reactions in water due to the destruction of the hydration layer as mentioned above, while at the same time bringing the organics, complex ions, anions and electrons in the water to a higher energy state. It is possible because it is activated.

Under these conditions, both the positive electrode and the negative electrode are inert carbon electrodes, and the electrolysis is performed while changing the polarity for a predetermined time, and the present inventors devised a method for treating industrial wastewater continuous electrolytic purification and its apparatus (Patent 10-0188232). It is possible to purify waste water much more quickly.

At this time, the alteration of the polarity is to prevent the overvoltage generated in the anode and to increase the electrolytic purification treatment efficiency by removing the sludge stuck to the anode in the sludge dispersed in the water.

Such wastewater treatment is the most suitable and economical method for the advanced wastewater purification treatment because it has a particular effect on the removal of COD, BOD, SS, as well as denitrification, dephosphorization, decolorization and deodorization.

In the present invention, if the high purification treatment is to be connected in series with multiple wastewater treatment device, if you want to increase the treatment capacity would be connected to the wastewater treatment device in parallel.

In addition, when the waste water 4 is to be treated continuously, A and B waste water treatment devices are connected in parallel, and when the A waste water treatment device is operated, the B waste water treatment device discharges the treated waste water 4 and On the contrary, when the B wastewater treatment system is operated, when the A wastewater treatment system is alternately operated by discharging the treated wastewater 4, the wastewater 4 can be continuously treated, thereby doubling the wastewater 4 purification capacity. You can.

As described above, the present invention is capable of bubbling anions and ozone containing radicals and electrons into various wastewaters, such as dyeing wastewater, leather wastewater, petrochemical wastewater, and papermaking wastewater, and livestock wastewater and domestic wastewater. Micro mixing at the molecular level that vibrates violently with ultrasonic waves at Hz to hydrate organic or heavy metal complex ions and radicals, electrons, and anions that are dissolved and hydrated in waste water. As volatile organic matter (VOC) is rapidly oxidized and decomposed in air by anion, it quickly cleanses and decomposes organic matter and complex ions in water, thereby causing various environmental pollutions caused by discharged wastewater. There is an effect that can be significantly reduced.
