High Density Plasma Device Coupled with Ultrasonic Wave and High Frequency Pulse for Waste Water Treatment

The present invention relates to a high-density plasma wastewater treatment apparatus combined with ultrasonic waves and pulse waves, and more specifically, industrial wastewater such as landfill leachate, dyeing wastewater, leather wastewater, petrochemical wastewater and paper wastewater, and various wastewater such as animal wastewater and domestic wastewater. When the anion or ozone containing radicals and electrons is bubbling into the wastewater, the ultrasonic level of 20,000 Hz to 40,000 Hz and the high frequency square pulse wave of 1 ㎑ to 100 MHz are simultaneously used to give the molecular level. Micromixed organic matter, heavy metal complexions, radicals, electrons, and anions that are hydrated and dissolved in the waste water, leave the hydration seath, and high-frequency pulses Break down and cause a gas-like reaction in water, causing ions or polar organic molecules to leave the hydration layer. Just as volatile organic matter (VOC) is rapidly oxidatively decomposed by anions in air, organic matters, complex ions, anions and electrons are activated in a higher energy state in the water and contaminants are rapidly oxidatively decomposed to COD, BOD, SS. Of course, since it has a special effect on denitrification, dephosphorization, decolorization and deodorization, it is to provide the most suitable and economical wastewater treatment apparatus for advanced wastewater purification treatment.

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 with the increase of the population and the development of the industry, and the environmental pollution and the destruction of the ecosystem caused by these problems are becoming a big social problem. The treatment method and method are doing a lot of research and steady research.

Conventionally, various methods of wastewater purification devices have been proposed, such as agglomeration (or precipitation) of contaminants with chemicals, treatment with microorganisms, but decomposition or material change of hardly decomposable pollutants such as surfactants in wastewater. 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, high-purity raw water with low COD, such as first-class or second-class water, can be highly purified with ozone, but high concentration industries such as leachate from landfills, high concentration livestock waste and dyeing wastewater, petrochemical wastewater, paper wastewater and sugar wastewater It is almost impossible to purify waste water with ozone.

Therefore, the present invention is to discharge anion or ozone containing radicals and electrons into various wastewaters such as landfill leachate, dyeing wastewater, leather wastewater, petrochemical wastewater and paper wastewater, and various wastewaters such as livestock wastewater and domestic wastewater. If you use the ultrasonic wave of 20,000Hz ~ 40,000Hz and the high frequency square pulse wave of 1㎑ ~ 100MHz at the same time, you can micro-mix at the quasi-molecular level by ultrasonic wave to dissolve and hydrate in waste water. The presence of organic or heavy metal complex ions, radicals, electrons, and anions leave the hydration seath, and high-frequency pulses destroy the hydration layer, causing gas-like reactions in water. It causes ions and polar organic molecules to leave the hydration layer, so that volatile organic matter (VOC) in the air Like oxidative decomposition, organics, complex ions, anions and electrons are activated in a higher energy state in the water, so pollutants are rapidly oxidatively decomposed and have a particular effect on the removal of COD, BOD and SS as well as denitrification, dephosphorization, decolorization and deodorization. It is an object of the present invention to provide a wastewater treatment apparatus that is most suitable for the wastewater altitude purification treatment.

In general, plasma generated by direct current discharge by high voltage and low current in air is composed of ions, radicals, and electrons. In this case, the corona discharge 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. Call. However, since the spark discharge mainly produces ozone (O ₃ ), the plasma generator is called an ozone generator.

On the other hand, when the present inventors bubbling air, oxygen or ozone or a mixture of these while electrolytic (electrolytic) treatment of industrial wastewater as proposed in Patent No. 10-0188232, the chromaticity of the industrial wastewater , Chemical oxygen demand (COD), biological oxygen demand (BOD), and dispersed solid particles (SS) particles are greatly reduced, and industrial wastewater is purified.In addition, chlorine compounds or mixtures thereof are placed in industrial wastewater and anion and ozone or hypochlorite ion, due to the oxidation of (ClO ₁ ^{-) -} in when ring a mixed gas bubble chloride ion (Cl), chlorite ion (ClO ₂ ^-), chlorate ion (ClO ₃ ^-) and the hypochlorite ion (ClO ₄ ^- ), The solubility of oxygen in industrial wastewater is greatly increased.

In addition, when the low-voltage (1V to 100V) direct current or high frequency alternating current pulse is applied to industrial wastewater containing such chlorate ions, oxygen ions (O ₂ ⁻ ) having high energy are separated from these chlorate ions. By attacking chromophores or chromophores of dye molecules or pigment molecules with higher efficiency than Korean Patent No. 10-0188232, oxidative decomposition of these molecules greatly reduces the chromaticity, COD, BOD and SS of industrial wastewater, and purifies them. .

In general, high-purity raw water with relatively low COD, such as first-class or second-class water, can be treated with ozone, but high concentration industrial wastewater such as landfill leachate, high concentration livestock wastewater, dyeing wastewater, petrochemical wastewater, paper wastewater and sugar wastewater. Is almost impossible to purify with ozone.

However, while bubbling into the wastewater, anion or ozone generated using the high-density plasma generator of Patent Application No. 10-1999-0036738 (August 31, 1999) filed by the inventor including radicals and electrons, By using ultrasonic wave of Hz ~ 40,000Hz and high frequency square pulse wave of 1㎑ ~ 100MHz at the same time, it is micro-mixed to quasi-molecular level by ultrasonic wave and dissolved in waste water to hydrate organic matter or heavy metal Complex ions, radicals, electrons, and anions leave the hydration seath, and ions or polar organic molecules leave the hydration layer by pulse propagation.

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 and pulse propagation destroy the hydration layer as mentioned above, resulting in gas-like reactions in water and at the same time more organic matters, complex ions, anions and electrons in water. This is possible because it is activated in a high energy state.

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

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 the wastewater is fresh water, and a reactor (6) for circulating the wastewater (4) of the decomposing tank (2), wherein the reactor (6) purifies the wastewater (4). A main reaction chamber and an auxiliary reaction chamber to be treated; 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 with ultrasonic waves; And an anion and ozone generator for dissolving and purifying.

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 water supply pipe 8 and a water discharge pipe 10 are respectively installed to supply the wastewater to be treated and discharge the treated wastewater.

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 semi-submerged 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 digester 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, as shown in FIG. 2, when the reactor 6 is installed outside the digester 2, a removable scraper 126 is installed on the digester 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, 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 so that the waste water purification reaction in the reaction chamber 14 is sufficient Make it happen.

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 anion or ozone from being destroyed and shortening the lifespan. The inlet tube 16 includes an air stone filter 20 and a pump. (22) is installed so that the wastewater (4) of the digestion tank (2) is filtered and then introduced into the reaction chamber (14) by the pump (22) for repeated purification.

The purified wastewater 4 is discharged to the decomposition tank 2 and is circulated while repeating the flow into the reaction chamber 14, and a plurality of inclined plates 22 are provided at the inlet of the reaction chamber 12. The fixed wastewater 4 is swirled in a swirl (quasi-aeration state) to achieve an effective purification reaction.

A secondary reaction chamber 26 having a size smaller than that of the reaction chamber 12 is formed between the outlet 24 and the outlet pipe 16 of the reactor 6, which gradually narrows, allowing 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 If it can be fixed without the loss of ultrasonic waves, it may be a cylindrical shape, but it is preferable to form a polygonal structure before and after the octagonal shape so that the ultrasonic vibrator 28 can be fixed in close contact with the cylindrical shape as shown in FIG. 3.

An ultrasonic band is fixed by fixing a plurality of ultrasonic vibrators 28 generating ultrasonic waves of 20,000 Hz to 40,000 Hz by an ultrasonic wave generator (not shown) for each outer surface of the polygonal case 12. (32), the ultrasonic band 32 is to be provided in two or more plural in consideration of the length and size of the reactor (6).

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. Ultrasonic waves of ˜40,000 Hz separate the semi-molecular state while vibrating the waste water 4 violently.

Therefore, organic matter, heavy metal complexes and radicals, electrons, and anions dissolved and hydrated in the wastewater 4 escape the hydrated water seam, 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 like oxidative decomposition in an instant, the wastewater 4 is purified quickly and cleanly.

In addition, the reaction chamber 14 is provided with a pair of one or more high frequency pulse applying electrodes 104 and 106 to which the high frequency pulse power supply 102 is supplied as shown in FIG. 1 to allow the wastewater 4 to be electrolytically treated. .

The high frequency pulse applying electrodes 104 and 106 may be made of carbon or stainless steel having chemical resistance to withstand wastewater, and may be formed of a rod, but may have a planar shape with a large surface area to improve electrolytic efficiency. Try to improve.

At this time, the sludge in the wastewater adhering to the high frequency pulse applying electrodes 104 and 106 by the high frequency pulse power supply 102 is easily removed, and the phenomenon that the sludge adheres to the ultrasonic wave and the high frequency pulse applying electrodes 104 and 106 is suppressed. do.

4 is a diagram illustrating a structure in which the high frequency pulse applying electrodes 104 and 106 fixed to the case 12 can be fixed while being insulated.

That is, a through hole is formed in the case 12, and then the nut 110 is brought into contact with the outer surface to be welded in a watertight manner, and the o-ring 112 is fitted to the nut 110 and the flange portion 114 is formed therein. The insulating nut 116 of the same material as the light is fastened to maintain the watertight between the nut 110 and the insulating nut 116, and the high frequency pulse applying electrodes 104 and 106 are formed in the inner hole of the insulating nut 116. The fastening and insert the screw rod 120 is coupled to the outer ring O-ring 118, the feed washer 122 is inserted into the outer surface of the screw rod 120 protruding outward and then fastened with a nut 124 to fasten the high frequency pulse The watertight of the application electrodes 104 and 106 is fixed so as to be maintained.

In the above, the insulation distance is maintained between the case 12 and the high frequency pulse applying electrodes 104 and 106 to prevent the undesired discharge, and the nuts 110 and the flan that the O-rings 112 and 118 directly contact. When the mounting portion 114, the high frequency pulse applying electrode 104, 106, the insulating nut 116 is formed with a recessed groove into which a part of the O-rings 112 and 118 can be inserted and tightened with the nut 124, respectively. The O-rings 112 and 114 are prevented from being misaligned or displaced.

On the other hand, a high density plasma generator 34 is installed on the case 12 of the reactor 6 to dissolve the water layer hydrated by ultrasonic vibration by dissolving high density (large amount) of anion and a small amount of ozone in the waste water 4. Allow out-of-water wastewater 4 to be effectively and quickly purged.

An air supply fan 36 is installed at an inlet of the high-density plasma generator 34 as shown in FIG. 1, and an air supply fan can adjust the air supply while blowing air at 2 to 5 atmospheres. Bloa fan: 38, the check valve 40 to prevent the backflow of air, and the electric dust collector or bio-dust filter 42 to prevent the inflow of impurities, the filtered air is supplied without high flow back flow Negative ions and a small amount of ozone are 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.

FIG. 5 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. Positive plate 66 and negative plate 62 allow insulation to be maintained at appropriate intervals in housing 48.

The negative electrode plate 62 and the positive electrode plate 66 are connected to the feed lines 68 and 70 to which the high voltage portion (HV) is connected, and the positive electrode rod 74 having an outer diameter smaller than the inner diameter of the negative electrode tube 72 inside the negative electrode tube 72. ) And spaced apart so that the anode rod 74 and the cathode tube 72 do not come into contact with each other to form a vent hole 76 which is a discharge space therebetween, and the high voltage unit HV uses a commercial power supply of 3,000V to 25,000V. The voltage is boosted with a current of several A at several μA and then supplied to the positive electrode plate 66 and the negative electrode plate 62 so as to generate plasma P by corona discharge.

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 6, the lower portion of the cathode tube 72 where the discharge chip 78 is located 6, 7, as shown in Figure 7, a plurality of discharge holes 80 are formed at narrow intervals, 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. By generating corona discharge up and down at the center, high density (large amount) of anion and a small amount of ozone (O ₃ ) can be obtained, which is 30% more efficient than the conventional method by the action of high density plasma (P) and plasma. Make sure

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, the discharge portion 82 of the discharge hole 80 has a corner structure that forms an angle of about 90 ° so that the discharge charges are concentrated, so that the corona discharge efficiency is maximized by the action of the discharge chip 78 and accordingly high density. Since high plasma P is generated, air is discharged by anionization and ozonation at high density.

In the above, a strong corona discharge and aeration of the wastewater 4 are made by the pressure air of 0.2 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 the corona discharge, a large amount of air is supplied to the vent holes 46, 64, 76 by the air pressure source (not shown), thereby preventing overheating of the anode rod 74 and the cathode tube 72. In addition, due to the air pressure difference 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 is vented through the discharge hole 80. Since it flows into the interior of the 76, the heat dissipation effect of the anode rod 74 and the cathode tube 72 is enhanced.

8 is an exploded perspective view showing another embodiment of the electrode used in the high-density plasma generator 34, in which the discharge chips 84 in the form of pyramids (square pyramids) are densified on the longitudinal and circumferential outer surfaces of the anode rod 74. As shown in FIG. It is formed at intervals one by one, and the discharge holes 86 are formed in the cathode tube 72 at a position corresponding to the discharge chip 84 1: 1, respectively, so that the corona discharge is generated as an entire portion of the electrode.

The materials of the anode rod 74, the cathode tube 72, the anode plate 66, the anode plate 62, and the discharge chips 78 and 84 are heat resistant, such as molybdenum, tungsten, nickel, platinum, nickel, molybdenum, copper, and the like. And an alloy material having excellent acid resistance and conductivity, and the anode plate 66 and the cathode plate 62 to which the anode rod 74 and the cathode tube 72 are fixed are also formed of an alloy material having excellent heat resistance, acid resistance and conductivity as described above. Therefore, the thermal expansion coefficient is excellent while the heat resistance, acid resistance and conductivity are excellent.

The high-density plasma generator 34 may be installed in one or more, as shown in Figure 9 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. Since it can be a circuit) to install a dehumidifier 88 of the type shown in FIG.

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 heat transfer heaters 90, which are powered by an unillustrated switch, are connected in series to heat the high density plasma generator 34 to 150 ° C to 300 ° C when the high density plasma generator 34 is initially operated. It is possible to remove the evaporated water and moisture penetrated or penetrated between the anode rod 74 and the cathode tube 72 to prevent the electrical short circuit or failure of the high-density plasma generator 34, the heat transfer heater 90 and the temperature The switch 92 is wrapped in the case 94 to protect.

11 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 in 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, the case 12 and the case 12, the case 12 and the high-density plasma generator 34 is fastened in a flange structure having a watertight holding means to facilitate repair, movement, disassembly and assembly, and reaction.

In addition, the preliminary digestion tank 58, the primary and secondary digestion tanks 2, 2a, the coagulation (or sedimentation) tank 202, and the pH storage tank 210 are bent drain pipes 212, 214, and 216. By using 218, the wastewater 4 is moved to a cell located next to it, thereby reducing the production cost and occupying the minimum space. In addition, the device is a continuous high-density plasma wastewater treatment device capable of continuously treating wastewater, so the wastewater treatment effect is much higher than that of a discontinuous badge type device, and it is an automated device.

A plurality of primary and secondary disassembling tanks (2) (2a) are circumscribed to the lower end of the cell (about 300 mm to 500 mm from the bottom) and the upper part of the cell (about 300 mm to 500 mm down from the top of the cell). Ultrasonic bands 178, 180 consisting of two ultrasonic vibrators and protective cases are installed in two rows, and a pair or several pairs of high frequency pulse applying electrodes 188, 190 made of carbon or stainless steel in the center thereof. After installing (192) (194), a high frequency pulsed power source (182) of 1 kHz to 100 MHz is applied to deliver.

In addition, when the electrolysis device of Patent Application No. 10-0188232 filed by the present inventors is additionally installed, there is a special effect on the high-color dyeing wastewater or sugar wastewater purification treatment.

In the flocculation (or precipitation) bath 202, inorganic flocculation (or precipitation) agents (aluminum sulfate, ferric chloride, PAC) and organic flocculation (or precipitation) agents (anionic or cationic organic flocculation (or precipitation) agents) By adding an appropriate amount to pressurize the air using the air supply fan 198, and then install a sludge removal device and a sludge storage tank (not shown) in which sludge is removed by the scraper 126 in the same manner as the preliminary digestion tank 58. The sludge 160 or foam floating on the water surface 158 of the tank 202 can be removed by a sludge storage tank, and a bubbling device 200 having an air supply fan 198 is installed in addition to the sludge removing device. To press the sludge under pressure so that the scraper 126 can be easily removed.

In the case of the sludge removal apparatus, as shown in FIG. 12, a pair of chain gears 132, 134, 136 and 138 are arranged on both sides of the upper part of the preliminary digestion tank 58, and the shaft 140, 142 and the shaft bearing 144. After installing the shaft to the chain (146) (148) by hanging the parallel to the end, one side of the shaft 142 by connecting the rotating shaft of the reduction motor 150 to the chain 146 (148) to rotate the interlocking The chain attachments 154 and 156 fixed to both ends of the connecting rods 152 are fixed to inner surfaces of the chains 146 and 148 so as to circulate and rotate along the chains 146 and 148 and the connecting rods 152. 13, the sludge 160, foam, and the like, which float on the constant surface 158 of the preliminary digestion tank 58, are fixed to the sludge storage tank 162 by inclinedly fixing the scraper 126 made of a light and durable chemical resistant material as shown in FIG. 13. It was made possible.

In the above, the scraper 126 is fixed to the chain attachments 154 and 156 so as to enter the wastewater 4 when positioned in the lower chain, so that the sludge and bubbles are moved to the sludge storage tank 162 while moving along the chain. When it is located in the upper chain, it is lifted by the air so that floating sludge or foam does not move in the reverse direction.

The bubbling device 200 is installed at the bottom of the agglomeration (or sedimentation) tank 202 and the air supply fan 198 at the end of the connecting pipe is installed in the pipe formed with a narrow spaced injection hole on both sides and the top surface. Bubbling into the wastewater 4 allows for the removal of pressurized sludge with the scraper 126.

Further, in the pH reservoir 210 by using an acid (HCℓ, H ₂ SO _4), alkali (sodium hydroxide NaOH) to adjust pH to 7-8. The treated water is transferred to the microbial reaction tank through the discharge pipe 208, and then discharged.

In the present invention, the preliminary digestion tank 58, the primary and secondary digestion tanks 2 and 2a, the coagulation (or sedimentation) tank 202, and the pH adjusting tank 210 have a drain valve as shown in FIG. Each of the (206) is installed so that the waste water (4) can be discharged when the sediment deposited on the bottom or cleaning is required.

In the present invention, the preliminary digestion tank 58 and the flocculation (or sedimentation) tank 202 are provided with a sludge removal device having a scraper 126. 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 bend-type drain pipe 212 and 218 of the coagulation (or sedimentation) tank 202 are provided with a water level control device 220 having the configuration as shown in FIG. It is possible to precisely adjust the level of the flocculation (or sedimentation) tank 202 according to the state and height of the sludge.

As for the water level control device 220 as shown in Figure 17 drain pipe 224 opened upward to the outlet 222 of the preliminary digestion tank 58 and the coagulation (or sedimentation) tank 202 is raised and protruded, the drain pipe The collection pipe 226 which is raised more than the drain pipe 224 is installed on the outside of the 224, the primary decomposition tank 2 and the pH storage tank 210 in one lower portion of the collection pipe 226 opened to the upper side ), The outlet pipes 212 and 218 are connected.

One or more O-rings 228 and the water level control pipe 230 are loosely installed in the drain pipe 224 so that the water level control pipe 230 can be elevated, and positioned between the drain pipe 224 and the water level control pipe 230 ( 228 maintains watertightness.

Is screwed to the nut 240 is fixed to the connecting rod 238 to the collecting pipe 226 or other fixing means, so that the rise or fall of the water level control pipe 230 is achieved according to the rotation direction of the handle 234 The water level of the preliminary digestion tank 58 and the flocculation (or sedimentation) tank 202 provided with the sludge removal apparatus can be adjusted precisely.

18 is a wastewater treatment flow chart of the present invention ultrasonically coupled high density plasma wastewater treatment apparatus. Here, the preliminary decomposition tank 58 is attached with an ozone generator, an ultrasonic generator and a scraper 126.

As described above, the preliminary decomposition tank 58 removes the hydrated layer of organic compounds, heavy metal complex ions, and ozone molecules dissolved in the waste water by ultrasonic and high frequency pulses, and at the same time is activated in a high energy state. Due to the great effect of oxidative decomposition of organic molecules and complex ions, COD, BOD, SS, TN, TP reduction rate of waste landfill leachate and high concentration livestock wastewater is excellent, and the effect of decolorization and deodorization is very high.

In addition, since the sludge is removed by the scraper 126, the reduction rate of SS generated by agglomeration (or precipitation) of the preceding molecular decomposition residue is also large. The primary digester has the same effect as the preliminary digester because the anion generator, the ultrasonic generator, and the high-frequency pulse device are attached, except 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 aggregated (or settled) by an inorganic flocculant (or precipitation) agent such as aluminum sulfate, ferric chloride, or PAC, or an ionic organic flocculation (or precipitation) agent. Or pressurize. The secondary digester has a structure in which a high frequency pulse applying device is added to the primary preliminary 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 are added to the treated water that has passed through the high-density microbial reaction tank. After precipitation, SS is adsorbed in the activated carbon adsorption tank and the next step is a hollow fiber membrane filter or RO (reverse osmosis) ultrafiltration. The ultimate purpose is to treat and reuse the wastewater, so that it is possible to so-called undischarged wastewater treatment that only replenishes evaporated or lost water and does not discharge the wastewater at all.

FIG. 19 omits the secondary preliminary digestion tank in the flow chart of FIG. 18 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 having a dephosphorization degree of 95% or more.

In the present invention, the test results of the physicochemical wastewater treatment apparatus which is the most effective so far in the pretreatment of the high-density microbial treatment and the general microbial treatment in FIGS. 18 and 19 are shown in Table 1 below.

As shown in Table 1, COD = 1,927.0ppm, BOD = 2,470.5ppm, SS = 4,782.0ppm, TN = 1,397.0ppm, TP = 99.7ppm, and the removal rate of the leachate preliminary leachate of raw water is COD = 67.5%, BOD = 50.1 %, SS = 95.7%, TN = 22.3%, TP = 95.3%.

However, except for 45.2% of T-N removal rate, primary decomposed water ranged from 86.3% to 98.5%. However, except for T-N = 73.5%, the removal rate of the secondary cracked water exceeded 97% of all water treatment items.

T-N = 73.5% is the highest removal rate among all wastewater treatments carried out to date. Here we demonstrate the advantages and superiority of ultrasonic and pulsed wave combined high density plasma wastewater treatment. The device also 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 the molecular level. (Micro mixing) and polar organic molecules or heavy metal complex ions and radicals, electrons, and anions that are hydrated and dissolved in the waste water by high-frequency pulses 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 and high frequency pulses cause gas-like reactions in water due to the destruction of the hydration layer as mentioned above, while at the same time increasing organic, complex ions, anions and electrons in water. This is possible because it is activated in an energy state.

Under these conditions, both the positive and negative electrodes are inert carbon electrodes or stainless steel electrodes, and electrolysis is performed by changing the polarity at a predetermined time. 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 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 purification of wastewater because it will have 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 wastewater 4 is to be treated continuously, A and B wastewater treatment devices are connected in parallel, and when the A wastewater treatment device is operated, the B wastewater treatment device discharges the treated wastewater 4. 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 made while bubbling anions and ozone containing radicals and electrons in various industrial wastewaters such as landfill leachate, dyeing wastewater, leather wastewater, petrochemical wastewater, papermaking wastewater, and various wastewaters such as livestock wastewater and domestic wastewater. Micro-mixing at the molecular level, which vibrates violently with ultrasonic waves and high frequency pulses of 20,000 Hz to 40,000 Hz, hydrated organics, heavy metal complexes, radicals, electrons and anions As it leaves the hydration seath, the volatile organic matter (VOC) is rapidly oxidized and decomposed in the air by anion. There is an effect that can significantly reduce the various environmental pollution caused by waste water.
