Description

High density plasma method and device coupled with ultrasonic wave for waste water treatment using magnet and tungsten catalyst

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonically coupled high density plasma wastewater treatment method using a magnet and a tungsten catalyst and a device thereof. Specifically, a tungsten metal catalyst which is an ammonia decomposition catalyst in the vicinity of a magnet installed in the wastewater treatment device is used. The dipole organics (organic dipoles) or heavy metal complex ions in the ammonia molecules or waste water are decomposed and processed while being in contact with tungsten by the magnetic force (suction force) of the magnet, and in parallel with the organic dipoles by ultrasonic waves, high density plasma and high frequency pulses. The intensive attack on ammonia molecules is to decompose and remove wastewater such as livestock wastewater and landfill leachate more effectively than before.

As environmental pollution and the destruction of ecosystems caused by various industrial wastewaters, which are rapidly increasing with the increase of population and industrial development, are becoming a big social problem, the legal environmental standards of discharged wastewater are prepared and strictly regulated. A lot of hard work and constant research is being carried out.

Generally, various wastewaters such as livestock waste, manure, garbage leachate, dyeing wastewater, and chemical wastewater contain ammonia, bipolar organic matter and heavy metal complex ions, and the wastewater containing various pollutants is relatively high in color. It not only contaminates water quality such as groundwater and seawater, but also blocks the light and oxygen coming into the water, causing enormous damage to the survival of aquatic organisms and microorganisms, and also affecting the production of water due to water pollution.

In the past, there have been various methods of wastewater purification (treatment) such as adjusting pH of wastewater with chemicals or chemicals, flocculating contaminants, treatment with microorganisms, etc. (Iii) Decomposition of degradable pollutants, purification and removal by material change and aggregation are difficult, so the purification efficiency is very low, but the treatment cost is rather increased.

In addition, high-purity raw water with low chemical oxygen demand (COD) such as primary or secondary water can be purified and treated with ozone, but leachate, high concentration livestock waste water, dyeing waste water, petrochemical waste water, paper waste water, It is almost impossible to purify and treat high concentration industrial wastewater such as sugar wastewater with ozone.

In addition, in the conventional case, since there is no collecting means for catching and attacking polar organic molecules or heavy metal complex ions in the wastewater, the organic molecules or heavy metal complex ions having these polarities run away, and thus, purification efficiency is greatly reduced.

Therefore, in the present invention, tungsten metal, which is ammonia decomposition catalyst, is placed in the magnetic domain under magnetic force, so that organic dipoles (organic molecules having positive polarity and negative polarity) or heavy metal complex ions in ammonia or waste water are attracted to the magnet and attract the magnet surface. It is aimed to greatly increase the purification and treatment effect of wastewater by the catalytic action of tungsten while being adsorbed on the surface.

In addition, an object of the present invention is to provide a wastewater treatment apparatus to which the wastewater treatment method can be applied.

In addition, the wastewater treatment apparatus can decompose and remove wastewater more effectively than before by intensively attacking the organic dipole which is decomposed and processed while being in contact with the tungsten surface by the magnet attraction force by ultrasonic waves and high density plasma or ultrasonic waves and high density plasma and high frequency pulse. It is intended to provide.

In addition, polar organics, complex ions, anions and electrons in the waste water are activated to higher energy states by ultrasonic waves and high frequency pulses to rapidly oxidize and decompose contaminants in the waste water, thereby eliminating COD, BOD and SS, as well as denitrification. It is an object of the present invention to provide the most suitable and economical wastewater treatment method for advanced wastewater purification treatment which has a special effect on dephosphorization, decolorization and deodorization.

In order to achieve the above object, a bar plate or plate-shaped tungsten catalyst is installed in the vicinity of (near) the magnet (magnetic force generating means) such as a permanent magnet or an electromagnet, or a catalyst plate surface-treated with tungsten. Ammonia, organic molecules, or heavy metal complex ions in the wastewater are attracted by magnetic attraction to effectively decompose and treat them in contact with the surface of tungsten.In addition to tungsten catalysis, organic molecules or heavy metal complex ions in wastewater are treated with high density anions. Intensive attack promotes further oxidation and decomposition of wastewater.

In other words, when ammonia and harmful organic dipoles in the waste water are adsorbed to the tungsten catalyst by magnetic force, oxidation and decomposition of the waste water are further promoted by concentrated attack of high density anions.

As such, the organic molecules or heavy metal complex ions adsorbed on the surface of the tungsten catalyst by magnetic force are vibrated with an ultrasonic wave of 20,000 Hz to 40,000 Hz while bubbling with anion and ozone containing radicals and electrons, and their chemical bonds ( The chemical bond is broken and oxidized and decomposed.

At this time, by micro-mixing with ultrasonic waves, ammonia, organic matter, heavy metal complex ions and radicals, electrons, and anions in wastewater escape from the hydration seath, which is like volatile organic matter (in air). As VOC) is rapidly oxidized and decomposed by an anion, ammonia, organic matter and heavy metal complex ions are quickly and effectively oxidized and decomposed in water and purified.

Under such reaction conditions, the application of an electrolytic device or a high frequency pulse of 1 MHz to 1 GHz simultaneously increases the catalytic and hydration layer destruction effects mentioned above, thereby further enhancing the purification treatment of high concentration industrial wastewater.

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

1 is an external perspective view of a magnet-tungsten catalyst 2 using a magnet of the present invention and a tungsten catalyst installed inside a reaction chamber of a wastewater treatment apparatus (wastewater purification apparatus), and a plurality of magnets- The tungsten catalyst plate 6 may be welded at appropriate intervals to form an integrated body, or as shown in FIG.

When the magnet-tungsten catalyst plate 6 is detachably attached, the support part 8 is formed on the outer surface of the support member 4 at appropriate intervals as shown in FIG. A pair of connecting portions 10 are protruded to one side, and then detachably coupled with fastening means such as bolts 12 and nuts 14 to remove or replace the magnet-tungsten catalyst plate 6 when repairing or replacing the magnet-tungsten catalyst plate 6. • Make it easy to attach.

In the above, the support member 4 may be configured as a full-bodied rod when the diameter is small, but when the outer diameter of the support member 4 is rather large, a through hole 16 is formed in the center of the support member 4 as shown in FIG. By inserting the tube 18 connected to the anion and ozone generating device to supply the anion and ozone, and to install the tube 18 in front of the magnet catalyst (2) to improve the anion and ozone contact efficiency.

In addition, when the cross-sectional shape of the reaction chamber of the wastewater treatment apparatus is circular or close to the circular shape, the magnet-tungsten catalyst 2 of the present invention may use the magnetic catalyst plate 6 as shown in FIG. When the shape is rectangular or close to the rectangle, as shown in FIG. 3, the magnet-tungsten catalyst plate 6 is integrally fixed to the outer surface of the rectangular support member 22 or the outer surface of the rectangular support member 22 to match the shape of the reaction chamber. After forming the plurality of protrusions 24, the plurality of magnet-tungsten catalyst plates 6 may be fixed by fastening means such as bolts 26 and nuts 28 so as to adsorb polar molecules in the wastewater. .

The hollow member 30 is formed inside the support member 22 to reduce the flow rate resistance, and in some cases, an underwater pump is installed in the hollow portion 30 to promote circulation and purification efficiency of the wastewater. There will be.

According to the reaction chamber size or the amount of purification of the wastewater treatment apparatus, the size of the magnet catalyst 2 may be decreased or one or more magnet catalysts 2 may be installed in the longitudinal direction or the width direction.

4 to 7 are cross-sectional configuration diagrams of the magnet-tungsten catalyst plate 6, in which a plurality of magnets 32 are arranged at appropriate intervals as shown in FIG. 4, and then chemical resistance on both sides of the magnets 32 is shown. An excellent soft magnetic material or a ferrous metal plate, such as a stainless steel case through which magnetic force passes, and then welded to maintain watertightness, the N pole plate 34 and the S pole plate 36 having a relatively large planar area as shown in FIG. The tungsten catalyst is provided in contact with the 34 and the S pole plate 36 or in the vicinity (nearby) of the N pole plate 34 and the S pole plate 36 so that the waste water can be effectively decomposed and treated by the catalysis of tungsten.

In the present invention, the shape of the magnet 32 is shown in a circular shape, but may be diversified into a square, rectangular, elliptical shape or a donut shape according to the situation or condition.

On the other hand, when the magnet 32 is arranged (arranged), as shown in FIG. 4, the regular arrangement can be achieved with the magnet 32, the N-pole plate 34, and the S-pole plate 36, but the magnet due to external impact or aging change Since the arrangement may collapse as the position of the 32 is changed, as shown in FIGS. 6 and 7, the spaces 44 and 46, which are processed with ferrous or nonferrous metals, are interposed between the magnets 32 and the uniform arrangement of the magnets 32. A uniform magnetic field is achieved and also the flow of the magnet 32 is prevented.

In the case where the material of the spaces 44 and 46 is a magnetic material, the magnetic uniformity and strength of the magnetic catalyst plate 6 are further improved to increase the adsorption effect of polar molecules or heavy metal complex ions in the wastewater. The catalytic effect of is greatly improved.

The magnet-tungsten catalyst plate 6 is fixed by a method such as welding directly to the support member 4 as shown in FIG. 4 to maintain watertightness, or the magnet-tungsten catalyst plate 6 configured to be watertightly retained in FIG. As shown in FIG. 2 and FIG. 7, the magnet-tungsten catalyst plate 6 configured to be fixed using the connecting member 42 or to be watertightly is supported using the connecting part 10 and the fastening means as shown in FIGS. 2 and 7. 8) can be combined so that they can be attached and detached.

Meanwhile, FIG. 9 illustrates a structure in which the tungsten rods 48 can be clamped by fixing a plurality of clamping pieces 58 and 60 having elastic force on both sides of the N-pole plate 34 and the S-pole plate 36. In the drawing, since the tungsten rod 48 can be easily attached and detached by the sandwiching structure, the tungsten rod 48 is easily replaced (replaced) or repaired.

In the above case, since the sandwich pieces 58 and 60 are fixed to the surfaces of the N pole plate 34 and the S pole plate 36, the tungsten rod 48 is located close to the magnet, so that the ammonia molecules or harmful dipoles in the waste water are separated from the magnet ( It is decomposed and processed while quickly adsorbing to the surface of the tungsten rod 48 by the suction force of 32).

Meanwhile, when fixing the tungsten rods 48 and 50, the tungsten rod 48 is installed in the vertical direction of the magnet-tungsten catalyst plate 6, as shown in FIG. 9, or the tungsten rod 50 as shown in FIG. The magnet-tungsten catalyst plate 6 may be installed in the horizontal direction, and the diameter and distance of the tungsten rod 48 may vary depending on the size of the magnet-tungsten catalyst plate 6 or the wastewater treatment capacity.

In addition, as shown in Fig. 11, a pair of support plates 62 and 64 having holes formed on the upper and lower portions or the left and right sides of the N-pole plate 34 and the S-pole plate 36 are fixed, respectively, and the support plates 62 and 64 are respectively fixed. Tungsten rods (66) and (68) are inserted into the through hole by force, or the tungsten rods (66) and (68) may be inserted and then fixed by welding or the like.

5 is a cross-sectional view of another embodiment for forming a tungsten catalyst according to the present invention. Tungsten is plated, sprayed, or sprayed on the surface of the N-pole plate 34 and the S-pole plate 36 and the copper plate 38 of a relatively large planar metal. The tungsten film 54 is formed by a method such as vacuum deposition, and harmful organic dipoles or heavy metal complex ions in the waste water are adsorbed and contacted with the tungsten film 54 by the suction force of the magnet 32. It is to be disassembled and treated.

In addition, micro mixing at the molecular level by vibrating with anion and ozone while vibrating violently with an ultrasonic wave of 20,000 kHz to 40,000 kHz or by applying a high frequency pulse of 1 MHz to 1 kHz with the ultrasonic wave and electrolytic device or the ultrasonic wave When concentrated attack on these polar organic molecules or heavy metal complex ions, the polar organic material or heavy metal complex ions and radicals, electrons and anions which are dissolved and hydrated of high density anion leave the hydrated water layer, and the high frequency pulse Ions, polar organic molecules, and heavy metal complex ions leave the hydration layer, causing volatile organic matter (VOC) to rapidly oxidize and decompose in water by anion. Or heavy metal complex ions, anions and electrons are activated to a higher energy state Pollutants in water and are rapidly decomposed and oxidized, because the removal of the COD and BOD and SS as well as exhibit the special effects to the denitrification and dephosphorization and decolorization and deodorization is best suited for highly purifying the waste water.

Therefore, polar organic molecules or heavy metal complex ions such as water (H ₂ 0), ammonium ions (NH ₄ ⁺ ), phenol, etc. are easily adsorbed on the surface of the tungsten catalyst by the magnetic force of the magnetic plates 34 and 36. It is oxidized and decomposed, and polar organic molecules or heavy metal complex ions are accelerated by anion attack to promote oxidation and decomposition.

For example, a tungsten-the ammonium ion adsorption to the surface of the magnet catalyst (NH ⁺ ₄₎ are as follows: reaction (1) by ultrasonic or high-frequency pulse NH ₄ ⁺ ions are protons (H in the molecules of water (H ₂ 0) ⁺ ) To produce hydronium (H ₃ ⁺ 0), which itself becomes a polar ammonia molecule (NH ₃ ), which is then adsorbed onto the magnet-tungsten (W) catalyst surface to absorb ultrasonic vibration energy and negative ions from the hydration layer. The N-H bond is broken by the attack and is decomposed into nitrogen gas (N ₂ (g)) and hydrogen gas (H ₂ (g)) as shown in the following reaction formula (2), and the ammonia nitrogen (NH ₃ -N) is purified. .

------------------------------------------ Formula (2)

12 is a cross-sectional view of the use state of the present invention, the decomposition tank 50a in which the wastewater 48a is freshwater is formed into a concrete structure or a chemically resistant cylindrical or polygonal metal structure according to the treatment capacity, and the decomposition tank A wastewater feedwater pipe 52a having a valve and a wastewater discharge pipe 54a having a valve are provided at both sides of the 50a to allow the wastewater to circulate or flow.

The reactor 56a installed inside or outside the digestion tank 50a is semi-submersible installed in the digestion tank 50a using a pair of tricycles 58a located at the left and right sides, or the digestion tank 50a. On both sides of the reaction chamber 60a of the reactor 56a, and an inlet pipe 64a through which the wastewater to be treated 48a flows in and a discharge pipe 64a through which the purified wastewater 48a is discharged. It is installed so as to be locked or connected to the decomposition tank (50a), and both sides of the reactor (56a) and the reaction chamber (60a) is formed to gradually narrow toward the inlet pipe (62a) and outlet pipe (64a).

When the reactor 56a is semi-submerged using the trivet 58a, the distal end of the inlet pipe 62a and the distal end of the outlet pipe 64a are spaced about 10 cm from the bottom by a decomposition tank 50a. In order to prevent the impact of the contact with the decomposition tank 50a, and to lower the center of gravity of the reactor 56a or to fix the trike (58a) by using a fastening means to prevent the rotation or flow of the reactor (56a).

In addition, in the case where the reactor 56a is installed outside the decomposition tank 50a, a scraper driven by a power source and a power transmission device is installed on the upper portion of the decomposition tank 50a so as to rise to the top of the decomposition tank 50a. Remove suspended solids or sludges such as

The inlet pipe 62a and the outlet pipe 64a 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 of the inlet pipe. The inlet pipe 62a has an air stone filter 66a and a pump 68a. ), The wastewater 48a of the digestion tank 50a is filtered and then introduced into the reaction chamber 60a by the pump 68a to be purified, and the purified wastewater is discharged to the digestion tank 50a. By repeating the cycle, and the inlet portion of the reaction chamber (60a) by fixing a plurality of inclined plates (70a) waste water (48a) flowing into the reaction chamber (60a) is effective by vortex vortex (quasi-aeration state) Allow the reaction to occur.

A secondary reaction chamber 74a having a size smaller than that of the reaction chamber 60a is formed between the outlet 72a of the reactor 56a and the outlet pipe 64a, which gradually narrows, thereby allowing the high density of anions to stay for a while. The wastewater 48a purified at 60a is moved to the auxiliary reaction chamber 74a so as to be sufficiently purified by another reaction.

In addition, since the cross-sectional area sizes of the outlet 72a portion and the outlet pipe 64a portion are much narrower than the cross-sectional area of the auxiliary reaction chamber 74a, the wastewater 48a flowing from the reaction chamber 60a is vortexed and aerated. The cross-sectional shape of the case 76a of the case (56a) may be cylindrical as long as it can be fixed without loss of ultrasonic waves. However, polygons close to the cylindrical shape, for example, polygons before and after the octagonal shape so that the ultrasonic vibrator 78a can be fixed in close contact with each other as shown in FIG. It is preferable to form into a structure.

A plurality of ultrasonic vibrators 78a generating ultrasonic waves of 20,000 Hz to 40,000 Hz for each outer surface of the polygonal case 76a are fixed, and then the protective bands 80a are covered to form an ultrasonic band 82a. ) In consideration of the length or size of the reactor 56a to be installed in one or more.

The ultrasonic waves generated from the ultrasonic vibrator 78a are concentrated by the polygonal case 76a structure to the center point of the reaction chamber 60a as shown in FIG. 13 so that the density of the ultrasonic waves increases toward the center and the vibration effect is amplified. Ultrasonic waves of 20,000 Hz to 40,000 Hz separate the quasi-molecular state while vibrating the wastewater 48a violently.

In addition, one or more magnet tungsten-catalysts 2 are installed in the reaction chamber 60a by using the support bars 2a.

Therefore, the magnetic tungsten-catalyst and ultrasonic and high frequency pulses and anions have the micromixing effect on the wastewater and the hydrated harmful organic molecules, heavy metal complex ions and anions in the wastewater. High concentration of industrial wastewater, livestock wastewater and landfill leachate due to the catalytic effect of adsorption and oxidation of ammonia molecules, organic molecules and heavy metal complex ions on the surface of the tungsten catalyst. The purification treatment effect is improved.

In addition, organic matter, heavy metal complexes and radicals, electrons, and anions dissolved and hydrated in the wastewater 48a escape from the hydrated water layer, and the volatile organic matter (VOC) in the air The organic matter and heavy metal complex ions in the wastewater 48a are rapidly oxidized and decomposed as quickly oxidatively decomposed, and the wastewater 48a is purified cleanly.

On the other hand, the high-density plasma generator 84a is installed on the case 76a of the wastewater treatment device to supply anions and ozone to the reaction chamber 60a.

An air supply fan 88a is provided at an inlet of the high density plasma generator 84a as shown in FIG. 1, and an air supply amount of air to be blown at 2 to 5 atmospheres is provided at the air supply pipe 86a. ), A check valve 90a for preventing the backflow of air, and an electrostatic precipitating or biodusting filter 92a for preventing 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 wastewater 48a.

In the above, the high density plasma generator 84a is installed somewhat higher from the constant surface of the wastewater 48a to maintain electrical insulation.

On the other hand, the high density plasma generator 84a prevents the backflow of the wastewater in the reaction chamber 60a by the check valve 90a, but the anode rod 116a and the cathode tube 110a are electrically shorted by evaporated water and moisture. The dehumidifier 130a may be installed on the outer surface of the case of the high density plasma generator 84a.

That is, the electric heat heater 132a is wound around the outer surface of the case 76a of the portion where the anode rod 116a and the cathode tube 110a are positioned, and the temperature switch 134a is applied to the surface of the case 76a. After the installation, the high-density plasma generator 84a is operated when the high-density plasma generator 84a is initially operated by connecting the electrothermal heater 132a, which is powered by a switch (not shown) in series, and covering the protective case 136a. Heat to 150 ℃ ~ 300 ℃ to dehumidify.

Therefore, by removing the evaporated water and moisture that has penetrated or penetrated between the anode rod 116a and the cathode tube 110a, an electrical short circuit or failure of the high-density plasma generator 84a is prevented.

If the dehumidifier is not installed, the distance between the discharge plate on which the discharge chips of the plasma generator are installed and the surface of the waste water is about 60 cm or more, thereby preventing the above-mentioned failure or deterioration of the plasma generator.

FIG. 14 is a cross-sectional configuration diagram of the high-density plasma generator 84a. A housing 98a having a locking portion 94a and a large-diameter vent hole 96a is inserted into a case 76a and fixed to the housing 98a. A plurality of ceramic insulating rings (100a) (102a) (104a) (106a) is laminated in the interior of the cover ring (108a) to be fixed, and a plurality of cathode tubes (110a) in the stepped portion of the lower insulating ring (100a) The negative electrode plate (112a) is fastened to each other, and a plurality of vent holes (114a) are formed in the stepped portion of another insulating ring (104a), and the positive electrode plate (118a) to which the plurality of positive electrode bars (116a) are fastened. The positive electrode plate 118a and the negative electrode plate 112a are inserted in the housing 98a so that the gap and the insulation are maintained.

A cathode rod 112a and a cathode plate 118a are connected to a feed line 120a and 122a 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 110a inside the cathode tube 110a. 116a is coupled to each other so that the anode rod 116a and the cathode tube 110a are spaced apart from each other to form a ventilation hole 124a therebetween.

The high voltage unit HV boosts a commercial power supply with a current of several A at a voltage of 3,000 V to 25,000 V and several mA, and then supplies them to the positive electrode plate 118a and the negative electrode plate 112a, respectively, to generate plasma by corona discharge.

On the other hand, the end of the anode rod 116a to form a needle-shaped plasma discharge chip 126a with a sharp tip, and a plurality of discharge holes (below the cathode tube 110a where the discharge chip 126a is located) 128a are formed at narrow intervals, and the lower end of the cathode tube 110a protrudes slightly downward than the anode rod 116a so that corona discharge is generated up and down around the discharge hole 128a located at the center. It is possible to obtain a high density (large amount) of anions and a small amount of ozone (O ₃ ) by the operation of the high density plasma and the plasma.

In the above case, the generation rate of anion and ozone is improved by 30% or more as compared with the conventional method. The discharge hole 128a may be installed in the cathode tube 110a as a whole, but since the concentration of charge may be dispersed, the discharge efficiency may be reduced, so that the discharge hole 128a may be installed around the discharge chip 126a where the discharge charge is concentrated. do.

In addition, since the discharge portion of the discharge hole 128a has a corner structure that forms an angle of about 90 °, the discharge charges are also concentrated and thus, the corona discharge efficiency is maximized and high density plasma is generated accordingly. In addition, the air is discharged by anionization and ozoneization by the action of plasma.

In the above, a strong corona discharge and aeration of the wastewater 48a are made by the pressurized air of 2 to 5 atm, and the discharge chip 126a whose end is sharply processed has a short life due to precipitation (elution) and abrasion. Since it may be formed, the life of the plasma discharge chip 126a may be extended by forming an oxide film by forming a conductive anti-oxidation material or coating the surface thereof.

In addition, even when discharge heat is generated by corona discharge, a large amount of air is supplied to the air vents 96a, 114a, and 124a by an air pressure source (not shown), thereby preventing overheating of the anode rod 116a and the cathode tube 110a. In addition, since an air pressure difference occurs between the inside and the outside of the cathode tube 110a due to the flow rate of the air flowing through the vent hole 124a, the air located outside the anode rod 116a passes through the vent hole 128a. Since it flows into the inside of the anode rod 116a and the cathode tube 110a is made of heat radiation well.

The materials of the anode rod 116a, the cathode tube 110a, the anode plate 118a, the cathode plate 112a, and the discharge chip 126a are made of heat resistance and acid resistance such as molybdenum, tungsten, nickel, platinum or nickel, molybdenum, copper, and the like.

The carbon electrode may be configured in the shape of a rod, but in a planar shape having a large surface area to improve the electrolytic efficiency.

At this time, periodically changing the polarity of the electrodes 146a and 148a by using the polarity alternating device 150a every 2 to 10 minutes, removes the sludge in the water clinging to the anode 146a and at the anode 146a. 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 146a and 148a by ultrasonic waves is significantly suppressed.

FIG. 16 is a cross-sectional view illustrating a state of use according to still another embodiment of the present invention. Instead of the electrodes 146a and 148a, a multi-electrode 154a to which a high frequency pulse power source 152a is applied may be installed so that a high frequency pulse may destroy a hydration layer. Gas-like reactions occur in the ions and polar organic molecules and heavy metal complex ions out of the hydration layer, so that volatile organic matter (VOC) is rapidly oxidized and decomposed by water in the air. Heavy metal complex ions, anions and electrons are activated to a higher energy state to rapidly oxidize and decompose.

Reducing the ratio is configured to occupy a minimum of space.

In addition, the device is a continuous high-density plasma wastewater treatment device capable of continuous wastewater treatment, and thus, the wastewater treatment effect is much higher and more automated than the discontinuous badge type device.

The bubbling device 176a pressurizes the sludge by installing a tubular body having narrowly spaced injection holes 194a at both sides and an upper surface at the bottom of the agglomeration tank 178a to allow external air to bubble into the wastewater 48a. Lift it up and remove it with a scraper.

In addition, pH-adjusting tank (184a), adjusted the pH using an acid _{(HCℓ, H 2 SO 4)} , alkali (NaOH caustic soda) to 7-8. The treated water may be transferred to a microbial reaction tank through the outflow pipe 64a for cooperative treatment and then discharged.

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

Therefore, the preliminary digestion tank 160a and the coagulation tank 178a are each provided with ordinary water level adjusting devices 196a and 198a in the bent drain pipes 186a and 192a. ), The water level can be precisely adjusted according to the sludge condition and height.

On the other hand, if the negative ions generated by the high density plasma generator 84a are pushed into the wastewater 48a by using air having increased broa pressure, the negative ions increase the number of collisions on the inner wall of the supply pipe, causing loss of negative ions due to destruction of the negative ions. do.

Therefore, in order to solve the above problem, in the present invention, an anion induction venturi having an underwater pump 200a as shown in FIG. 19 in the middle of the exhaust pipe 162a installed in the first and second decomposition tanks 168a and 170a. By installing the pipe (202a) to lower the pressure of the negative ion supply pipe to prevent the loss of negative ions and at the same time increase the initial mixing degree of the negative ions and waste water to increase the wastewater purification treatment by the negative ions.

That is, the water supply pipe 206a and the absorption pipe 208a are watertightly provided above and below the cylindrical body 204a to which the exhaust pipe 162a of the high density plasma generator 84a is connected, and the absorption pipe 208 is provided in the absorption pipe 208. Submerged intake pump 200a is supplied with power, and each of the water supply pipe 206a and the intake pipe 208a is formed with bottle necks 210a and 212a each of which gradually narrows in diameter, respectively. The bottleneck portion 210a of 206a is configured to have a smaller inner diameter than the bottleneck portion 212a of the water supply pipe 208a, so that the anion is dissolved in the waste water by the decompression effect of the exhaust pipe 162a, which is an anion supply pipe, so that It is to prevent the phenomenon that negative ions are destroyed by almost no collision count.

The pipe 214a connected to the water supply pipe 208a is provided with a valve 216a and a water supply funnel 218a so that water can be supplied at the time of initial startup.

The venturi tube 202a may of course vary in size depending on the specifications of the submersible pump 200a or the size of the processing capacity.

In addition, if the wastewater 48a is to be treated continuously, the two wastewater treatment devices A and B are connected in parallel, and then while the wastewater treatment device is operated, the wastewater treatment device B discharges the treated wastewater 48a. On the contrary, when the B wastewater treatment device is operated, the wastewater 48a can be continuously discharged by discharging the wastewater 48a treated by the A wastewater treatment device, thereby doubling the purification capacity of the wastewater 48a. You can.
