Development background

Recently, due to rapid industrialization and urbanization due to economic development, water pollution and demand for water are increasing rapidly, water depletion due to unrestricted use of water and lack of water due to water pollution are intensifying. Since they are discharged to rivers and seas intact, improvements in water quality, recycling of water resources and measures to prevent pollution are emerging as important social and economic issues.

In order to economically treat sewage treatment in pipes, many companies are doing a lot of research. Also, the sewage system which recycles sewage to industrial water, landscaping, toilets, agricultural water, etc. is of greatest concern.

In general, water treatment technologies for treating sewage include physicochemical and aerobic treatment, anaerobic treatment, biological treatment by animals and plants or microorganisms having unit processes such as flocculation, sedimentation, separation, adsorption, ion exchange, and oxidation. Multi-stage treatment is being developed that combines and links physicochemical treatment and biological treatment as unit processes.

Conventional screen filtration, flocculation by chemical input, sedimentation treatment, activated carbon filtration, etc. alone require a lot of operating costs, and do not provide efficient and stable water treatment, so that the treated water quality is not good, and biological treatment using activated sludge requires a large treatment space. And, it takes a long time to process, of course, requires professional management and there is a problem that the processing cost is excessive.

Recently, high-efficiency advanced treatment techniques using advanced engineering such as electrochemistry, magnetic force, plasma, and ultraviolet light, which have little chemical injection and little secondary pollution after treatment, are being developed one after another. Multistage treatment, which complements the shortcomings of the advanced and advanced treatment methods and uses them selectively in connection with water treatment, is becoming popular.

In addition, in the field of heavy water treatment, which is used once in homes or factories and treats water that is thrown away, it is generally used to treat purified water using activated sludge method and ultrafiltration membrane method. There is a problem in the water treatment efficiency, such as unnecessary expensive equipment to be installed, treatment cost increases, harmful microorganisms such as E. coli are not sterilized, and hardly decomposable organic substances remain.

In addition, the domestic sewage and sewage treatment system technology using the registered technology, the biofilm method and the advanced oxidation method maintains a constant flow rate even when excessive sewage from the water collection tank and the filtration tank is generated and removes contaminants for biological treatment. It is a biofilm formed by attaching microorganisms to a porous carrier with a flow control tank for adjusting load fluctuations, a temperature controller for adjusting microbial temperature conditions, and a compressor for supplying air to a rotating biofilm filter tank. Rotating biofilm filter tank for decomposing and removing degradable organic compounds A pH control tank for adjusting the pH of the wastewater in the rotary biofilm filter tank, and finally, sterilizing and disintegrating hardly decomposable and unprocessed organic substances using advanced oxidation method (AOP).

The registration technology of Patent Publication No. 2003-0055477 has a lot of initial facility costs, biofilm replacement costs, UV (UV) replacement costs, and processing efficiency is low. UV sterilization does not harm water bodies because there are no by-products or residues, but since there are suspended substances in sewage, foreign substances are covered by lamps caused by suspended substances. In addition, since the lamp is frequently damaged, the maintenance and maintenance cost is high, and it is not easy to remove organic matter or suspended matter in the sewage by ultraviolet rays.

In addition, the industrial wastewater heavy water treatment system technology, which combines foam separation method, hollow fiber membrane filter filtration method and advanced oxidation method, is a water collecting tank for collecting process water, and filtering the contaminants and suspended solids in raw water flowing into the collecting tank. Filtration tank, and the flow rate of the filthy water passed through the filtration tank to maintain a constant flow even under peak load, and the flow control tank that adjusts the load fluctuation of the contaminant for biological treatment and bubbles generated and flocculate the aggregate bubbles to the water surface Foam flotation tank that separates sludge quickly and efficiently, UV sterilizer to clean and dissolve and decompose hardly decomposable and untreated organic material by using advanced oxidation method (AOP), the ultraviolet (UV) Hollow fiber UF membran to remove bacteria and viruses from sterilized treated water in sterilization tank e), a treated water storage tank and a post-treatment apparatus for storing the wastewater purified by the hollow fiber ultrafiltration membrane filter, and for reprocessing sewage containing sludge and water which is processed and overflowed and returned from each tank. In the industrial wastewater heavy water treatment system, which consists of a drain tank for storing and a filter press, which is a dewatering device for physically compressing and filtering sewage containing contaminants and separating solid-liquid, the foam flotation tank at the front end spreads and decomposes organic matter. Foam separation method, hollow fiber membrane, characterized in that easy to separate the membrane by combining the hollow fiber ultrafiltration membrane filter (Hollow fiber UF membrane) in a continuous process after the organic matter is decomposed and removed by ultraviolet (UV) sterilizer There is an industrial wastewater treatment system that combines filter filtration and advanced oxidation processes.

Industrial wastewater heavy water treatment system technology that combines the foam separation method, hollow fiber membrane filter filtration method and the advanced oxidation method, the installation site or facility cost as a complex facility up to several times, the hollow fiber ultrafiltration membrane filter replacement cost In addition, it is expensive to maintain and repair UV rays, and because there are suspended solids in the wastewater, and foreign substances are covered by the lamps due to the suspended solids. The efficiency is lowered.

And air is a device that is discharged to the atmosphere.

In the above apparatus, the main parts of the construction and operation of the present technology will be described in more detail by exemplifying [FIG. 1], [FIG. 2], [FIG. 3] as follows.

Ozone generator (700) of FIG.

The ozone generator 700 applied to the present technology development is applied to the present technology development by a conventional known technique.

Ozone (Ozone, O3) is an allotrope of pure oxygen with a molecular weight of 48, a boiling point of -112, and a specific gravity of 1.67, in which oxygen (O2) and oxygen atoms (O) are unstablely bonded.

Near-surface ozone is also produced by pollutants, but mainly in the natural state. When high voltage electricity, such as lightning strikes, is discharged, it is produced primarily during the photosynthesis of plants. It is for this reason that ozone concentrations in clean areas without pollutants are recorded high.

Ozone has beneficial effects on the human body such as harmful UV rays, harmful decomposition of pesticides and heavy metals, sterilization, deodorization, and air purification, while ozone has both side effects that adversely affect the respiratory system.

Ozone is easily reduced to oxygen, so it is not possible to store and use it like other gases. The half-life of ozone is 2 to 13 hours in air and about 15 to 30 minutes in water, depending on the ambient conditions.

In addition, ozone is reduced to oxygen immediately after the reaction while having a strong sterilizing power and degrading ability to harmful substances, so there is no secondary pollution or residual property, and its application is gradually increasing in everyday life as well as in the environment.

Ozone is also the second most potent bactericidal agent on earth. Ozone has 3600 times sterilization rate and 7 times more sterilizing power than chlorine. All bacteria and even viruses that do not die from ordinary fungicides are killed in a perfect way that destroys the cell membrane.

In addition, ozone removes pesticide decomposition, heavy metal removal, harmful organic decomposition COD, BOD, TN, TP, color, turbidity.

In addition, ozone has the highest potential difference (2.07 eV) next to fluorine and OH radicals, and thus removes all heavy metals, microorganisms and organic materials except platinum and silver in the process of reducing oxygen.

In addition, the amount of ozone dissolved in water melts about 10 mg / L at 1 atm. Short half-life prevents preservation. There is no secondary pollution since it is reduced to oxygen after a certain time. Although general disinfectants and disintegrators have been controversial over other pollutions as residual problems, regardless of their performance, ozone has no harmful secondary by-products other than oxygen.

For this reason, many scientists have discovered the efficacy of ozone and used it for water treatment in the late 19C, and many studies have newly revealed many powerful effects without secondary pollution. In addition to the application of the decomposition function, it is also used in the field of ultra-clean semiconductors requiring high cleanliness.

In addition, there are various methods of generating ozone, such as a silent discharge method, an electrolytic method, a photochemical method, and a high frequency electrolytic method. The method of the present invention uses a silent discharge method.

In addition, the principle of the silent discharge method is to place a replacement insulator in one direction of the electrode, and when an alternating current is applied between the electrodes, a discharge occurs in the space, whereby the acceleration electron (e) collides with the oxygen molecule (O ₂ ), causing a reaction.

In addition, ozone production and decomposition reaction coexist between the electrode and the electrode, and the ozone concentration increases when the discharge power is increased or the residence time is increased.

In addition, since high concentration ozone is difficult to decompose, in order to economically operate and save energy, ozone contact and dissolution efficiency technology are required.

Ozone Generation Principle: O + e → 2O + e

O + O ₂ + (M) → 2O ₂

Ozone Reaction Principle: O ₃ + O → 2O ₂

O ₃ + e → O + O ₂ + e

Ozone Fine Mixer (300)

In addition, the ozone fine mixer 300 of FIG. 2, which is applied in the present invention, is installed inside the reaction catalyst tank 400 by the technique applied to the present invention, and the inflow waste water is the ozone fine mixer 300 waste water inlet ( 301), the waste water is injected at a pressure of 3 to 4 kgf / cm 2, the vacuum is 600 to 700 mmHg / cm 2 in the process of spraying the ozone fine mixer nozzle 306, and the ozone generated by the vacuum is the ozone fine mixer. Injected into the ozone inlet 303, the injected ozone and the waste water are mixed and ejected into the acceleration passage 307 of the ozone fine mixer 300, and a vacuum occurs due to the ejected flow rate, and the ozone by the vacuum Reaction water enters into the reaction water inlet 303 of the fine mixer 300, and excess ozone in the upper portion of the reaction catalyst 400 enters the ozone fine mixer 300, the excess ozone inlet 305, and accelerates the ozone fine mixer 300. 307), the reaction water and the ozone micromixer furnace As ozone and sewage spewed into the bla 306 are spewed back into the acceleration passage 307, ozone is finely mixed in the wastewater.

In this process, the ozone generator concentration can be reduced by maximizing the ozone contact efficiency, and the oxidative decomposition efficiency of organic matter is increased in the housing. For this reason, the energy of ozone generator can be saved.

Reference numeral 500 of the catalyst composition of FIG.

In addition, the cocatalyst composition 500 of FIG. 1 applied to the present invention is supported by the inside of the cocatalyst reaction tank 400 as an important technique applied to the present invention, and is a cocatalyst for efficiently treating the heavy water treatment of the present invention. As a composition, 10-20 weight% of tourmaline tourmaline and monazite with respect to 100 weight part; 3 to 10% by weight of titanium dioxide; Carbon black graphite 3 to 10% by weight; 0.1 to 1% by weight of silver (Ag +); 30 to 60% by weight of acrylic resin and urethane; 0.5 to 3% by weight of a slip agent; It contains 5 to 35 weight% of a hydrocarbon solvent and a ketone solvent.

Further, the cocatalyst composition pulverized particle powder is 0.01 to 20 µm, preferably 0.1 to 10 µm.

As the kinetic energy of water such as light, collision, pressure, friction, and temperature change is transferred to the cocatalyst composition 500 treated as described above, the potential difference voltage (3.2 eV) is generated by activating the oxidative electric energy, and the electromotive force generation amount is 0.032 It is a technology of a system that generates A / cm 2, generates hydroxyl groups, oxidizes and cleans harmful substances and organics in sewage with oxidizing power stronger than ozone, and discharges them cleanly.

In addition, the electrocatalyst composition of the present invention is also used for water purification and air purification, conductivity, sedimentation prevention, antifouling, and electromagnetic shielding.

The function of the above catalyst composition will be described in detail as follows.

1.1.1 Tourmaline and monazite functions

Tourmaline monazite [monazite] of the present invention is chemically composed of (Ce, La, Y, Th) PO4, and spontaneously spectroscopy, and when water is present in the vicinity, hydroxyl (ionized) molecules are electrolyzed to electrolyze moisture (water molecules). To generate negative ions.

Tourmaline and monazite are borosilicates with hexagonal columnar crystals and are natural minerals in the hexagonal system. Tourmaline monazite crystals have the nickname of tourmaline because they have the property of generating electricity. The tourmaline crystal absorbs (adsorption) and divergence (repulsion) electrons in the atmosphere, and no matter how small the powdering process, the particles continuously generate a weak current of 0.06 mA in each particle. ) Is instantaneously electrolyzed against water. At this time, water is electrolyzed and molecules (H 2 O) are separated into hydrogen ions (H +) and hydroxyl ions (OH −).

The separated hydrogen ions (H +) are attracted to the negative electrode of the tourmaline particles and are combined with the electrons emitted therefrom to neutralize them, becoming hydrogen gas (H2) and diffusing and evaporating in the atmosphere. That is, water becomes alkali ionization. In addition, hydroxyl ions (OH-) combine with the surrounding water molecules to form a surface active substance called a hydroxyl (H3O2-) anion.

This is commonly defined as anion. That is, H 2 O is separated into H + and OH −, and the separated H + and OH − generate hydronium ions and hydroxyl ions.

H + + H2O-> H3O + (HYDRONIUM ION) OH- + H2O-> H3O2- (HYDROXYL ION)

Hydroxyl (hydroxyl) ions, ie, sole ions, from which hydrogen has been removed by tourmaline and monazite, are present in an unstable state in terms of energy because they exist contrary to this law. For this reason, Hydroxyl ions exist in an unstable state in water, so they rapidly move to the interface and arrange H-O-H groups toward the inside of the water and H of the O-H groups toward the outside of the water.

As such, the hydroxyl ions are stabilized to act as surfactants. In addition, the tourmaline monazite air purifying effect is a physical property of tourmaline, and no matter how small it is pulverized, the tourmaline physical properties and molecular structure do not change. The effects of water purification and air purification will be very high in that the production of anionic surfactants is maximized.

[Chemical Scheme]

1.2.1 Titanium Dioxide Function

Titanium Dioxide Photocatalysts in some chemical reactions do not change themselves and serve to change the rate or initiate the reaction. Photocatalyst refers to the catalysis of light energy. Photocatalysts include zinc oxide (ZnO) and cadmium selphide (CdS), but titanium dioxide that does not photodecompose itself is the most active.

When light hits titanium dioxide, it produces electrons with negative electricity and holes (micropores) with positive electricity. These electrons and holes have strong reducing and oxidizing power. Applying this reducing and oxidizing power to decompose water yields hydrogen and oxygen. Accumulate this to get heat and electricity when needed.

Photocatalyst refers to special catalysts (Catalyst of Photo-reactions) that accelerate the photoreaction by irradiating light on the surface of the catalyst. As with the general catalyst requirements, the photocatalyst participates directly in the reaction, but should not be consumed by itself, and accelerates the reaction rate through a reaction mechanism path different from the conventional photoreaction.

Photocatalytic reactions that convert light energy into chemical energy using photoreactive powders represented by TiO2 have been studied and studied for their use in the generation of hydrogen (H 2) through water decomposition and organic synthesis reactions. In addition, as environmental problems are rapidly emerging, "photocatalysts as environmentally friendly catalysts" that can use solar light, which is a clean and infinite energy source, have attracted attention. The use of photocatalysts for environmental purification has led to the reduction of CO2, the direct decomposition of NOx and SOx, the removal of odors caused by volatile organic compounds, and the purification of polluted rivers and lakes. Decomposition of NOx and volatile organic compounds is of great interest in terms of practicality.

In general, heterogeneous photocatalytic reactions proceed on the semiconductor surface. In the semiconductor absorbing light energy, electron transition from valence band to conduction band occurs, and the generated holes or electrons in the conduction band move to the adsorption material or surface functional group. To participate in the reaction. In this case, an electric field is formed due to the movement of electrons, and thus, a space charge region is formed in the surface portion of the semiconductor where bending of an electron band occurs.

Holes (h +) or electrons (e-) formed through this process are extinguished through one of the following three reactions.

(1) photocatalytic reaction

Aads (Adsorbent A) + h + → (Aads) + Bads (Adsorbent B) + e- → (Bads)-

(Aads) + + (Bads) → product

(2) change of grid

h + + lattice → (lattice) + (lattice) + → lattice reaction product

(3) recombination of holes and electrons

h + + e- → thermal energy

In the above reaction (1), the formation, the hole, and the electron are finally recombined, but the light energy already absorbed is used to supply the activation energy of the reaction. The semiconductor used in the reaction remains unchanged.

In the case of (2) the reaction, the semiconductor used in the reaction causes the semiconductor itself to change as the reaction proceeds. In fact, sulfide-based semiconductors such as CdS easily cause photocorrosion in aqueous solution by irradiation of light.

The reaction of (3) is a case where the generated holes and electrons do not participate in the photocatalytic reaction and recombine directly. Therefore, the bending of the electron band in the space charge layer causes the generated holes and electrons to move in opposite directions, thereby ultimately preventing recombination. As a result, the possibility of participating in generated holes, electrons, or catalytic reactions increases, which is an important factor in the heterogeneous photocatalytic reaction.

1.3.1 carbon black and graphite functions

The present invention is a functional black catalyst paint composition having a water quality and an air purification function. Carbon black is produced by incomplete combustion of natural gas by heating wood at a high temperature while blocking air. Are arranged.

They have excellent adsorptive power and are used as decolorizing deodorant. Called fullerenes in particular, they are shaped like balls. In the C60, for example, 60 carbons are rounded together like a soccer ball. Sixty carbon atoms combine in a hexagonal shape like most graphite, and some have a five-sided shape.

In addition, they not only conduct electricity when redox, but also show superconductivity at low temperatures.

Natural graphite is composed of carbon, and most of the crystals are hexagonal and some are trigonal. Carbon is connected in a hexagon like a benzene ring, and these hexagons form a plate and form a continuous layer.

Carbon atoms have three strong covalent bonds in the plane of electrons, and one remaining electron is bonded to the upper and lower layers.

The height of one layer on the hexagonal plate is 3.40Å and the distance between the nearest carbons in the hexagonal ring is 1.42Å. The distance between the upper and lower layers of the platelets is much larger than the center distance of the two carbon atoms (the radius of the carbon atoms is 0.77Å and the carbon ions are 0.16Å).

For this reason, since the electrons upward on the hexagonal plate can move somewhat freely, graphite has good electrical conductivity.

Due to the good conductivity of graphite, the carbon atoms between the upper and lower platelets have an interaction and overlap with the valence electron band and the conduction band, and become 0.03 eV, and the same number of free electrons and holes are semimetallic. . The resistivity is about 100 times larger in the c-axis direction than in the other directions. There is no forbidden band, and the valence electron band and the conduction band are superimposed by the magnetic field, so they have a very large diamagnetic property, so the covalent bond is good and the oxidative energy is activated. It can block electromagnetic waves in the MHz to GHz region.

It does not react with hydrogen, nitrogen, and carbon dioxide even at high temperatures, but with halogens.
