1 is a block diagram of organic and odor in the wastewater according to the present invention, nitrification and denitrification of hardly decomposable substances, adsorption, decomposition, oxidation removal of volatile organic compounds, Figure 2 is a longitudinal cross-sectional view of FIG.

When the catalyst catalyst for nitrification and denitrification and volatile organic compound removal of the present invention is added to the aeration tank, sedimentation tank and deodorizer in the manure treatment plant, livestock wastewater treatment plant, sewage treatment plant,

In the sedimentation tank, the organic matter, odor, and hardly decomposable substances in the wastewater in the aerator are optimized as the catalyst for reducing the nitrification and denitrification cycle.

Therefore, the wastewater treatment time can be shortened, and the wastewater treatment efficiency can be increased.

On the other hand, if a catalyst filter for nitrification, denitrification, and volatile organic compound removal is added to the deodorizer, the volatile organic compound is safely removed by acting as a catalyst to adsorb, decompose and oxidize the volatile organic compound mixed in the waste water. will be.

As described above, the catalyst quenching agent for nitrification and denitrification and volatile organic compound removal which removes harmful substances in the waste water is formed in the annular recesses 15 of the circular frames 12 and 12a formed in the spherical body 10. The bead-shaped germanium (21), the illite (22), the bioceramic (23), the activated carbon (24), and the zeolite (25) are mounted so as to move freely to have a large surface area. 14a) is equipped with a ring-shaped germanium 31, an illite 32, a bioceramic 33, an activated carbon 34 and a Tio ₂ (35) zeolite 36 to treat the wastewater as described above. You can do it.

The characteristics of the constituents of the stimulants for oxidation, denitrification and volatile organic compounds removal are explained.

1) Germanium (21) and (31), which have electrical properties, have intermediate properties between metal and nonmetal, have four electrons in atomic structure, and are constantly coupled at room temperature to actively move between electrons and electrons. do.

Therefore, if a foreign substance is adsorbed or enters a specific cell or molecule, the outer electrons out of the four electrons are ″-″ negatively charged and bounce out, and the other three are ″ + ″ positively charged, leading to adsorption and neutralization in the object.

Germanium, which has the above characteristics, has an excellent oxygen supply ability, opens the passage between clogged cells and increases the activity of cells, thereby inhibiting the reproduction of harmful bacteria, dehydrogenating, and decomposing organic substances. H + ions are positive ions, which are of no use in cells. Germanium particles combine with OH- ions instead of H + ions to decompose and polymerize to remove odors, organic substances and toxic gases.

Since the germanium has a chemical property of having a highly oxidizing oxygen atom, it adsorbs heavy metals and chemically combines them to detoxify other substances that are not toxic to heavy metals.

2) The illite 22 and 32 are mica type clay minerals with biotite and represent minerals with high AL ² content.

Illite is composed of AL ² , Fe + ³ , Fe + ² , Mg + ² , TiO ² , K20, Na20 elements and the particle size is in the range of 0.5 ~ 2 μ.

As a natural mineral, far infrared rays of 9.36㎛ are emitted between 36.5 ~ 40 ℃, and emissivity is 95%, which is a report of essential mineral among minerals.

The above-mentioned illite emits 9.36㎛ far-infrared rays where the binding force between molecules acts on the water-molecule link chain polymerization ring, causing vibration by resonance and resonance movement to decompose the molecular connective tissue, and weaken the binding force. By stabilizing them prematurely to form FLoc, molecules with a higher specific gravity settle down to the bottom and decompose, and rarely as minerals, they absorb and decompose harmful germs and absorb odors or odors.

On the other hand, it generates a large amount of positively charged anion oxygen, the illite, far infrared rays promote the generation of a large amount of anion oxygen to generate anion oxygen of about 137 (ION / CC), and the molecules are H + ions and OH- It dissociates into ions, and instead of H + ions, the illite particles combine with OH- ions to dehydrogenate, and in particular, decompose colloidal organic materials.

In addition, by generating anion oxygen, the ion exchange power by the catalyst is increased to decompose pollutants by tsification and reduction, and to convert acidic and alkaline water into stone water, and a large amount of far-infrared rays are emitted to release a large amount of minerals. It quickly discharges harmful substances such as pesticides, heavy metals, and environmental hormones into the body. Types of adsorption of heavy metal ions

(Na, Al, Mn, La, Ce, Zn, Pb, Co, Ni, Fe, Cu, Cr, Sn) and the like.

3) Bioceramic (23) and (33) are composed of Si2 60%, A1 17%, Mg 0.1-12%, Feo 5-7%, Ge, Se, etc. Mainly used for wastewater treatment.

Bioceramic, which is composed as described above, is a substance having a composition having excellent emissivity of far-infrared rays, which is used to improve the structure of contaminated water by putting a ball shape or powder type into water or to directly attach the affected area to activate affected cells. It is used in countless places such as the wrapping paper of. The main effects are metabolic promotion, dehydrogenation, and deodorization of biological cells.In particular, resonance resonance is generated by the radiation of far-infrared rays, and vibration energy is generated to vibrate the molecules and atoms of the cells to remove heavy metals in the body. It is discharged out of the body, and the heavy metal is adsorbed and settled to the bottom by the dehydrogenation phenomenon.

4) Activated carbon 24 and 34 are generally classified into coal and plant systems, and the plant systems are mainly used for food industry, pharmaceutical, and wastewater treatment, and the coal systems are mainly used for wastewater treatment.

The activated carbon has a physical adsorption capacity as well as a role of ion exchange resin, that is, the same as the case of desalination of seawater that has passed through the coal bed. give.

In addition, due to the far-infrared radiation generated from coal itself and the exothermic reaction generated in the metabolism process of microorganisms, even if the outside temperature is below zero, the inside temperature is always maintained at 7-8 ° C. It shows the suppression of the growth of filamentous fungi, harmful microorganisms, and the liquefaction of protoplasts due to self-extinguishment when high concentrations of wastewater, etc. are introduced. This phenomenon does not deposit sludge on the bottom of activated coal streams.

Therefore, by using the surface area and the pores of activated carbon, DO concentration can be improved by more than 2 times compared with the existing treatment methods.In the case of powdered activated carbon, dehydrogenation effect occurs, instead of molecules of nitrogen compounds and organic substances and activated carbon particles H + ion. It combines with OH-ions to promote dehydrogenation, causing the heavy particles to settle to the bottom.

Nitrogen compounds and organic substances adsorbed as described above are oxidatively decomposed by physical decomposition devices installed in the decomposition reaction tank, and when activated and decomposed physically again, activated carbon itself is restored to its original state by the self-cleaning action. This is done continuously. The contact surface area is 100 X 10 m 2 / m 3, and the adsorption effect is more than 95%.

5) Zeolites 25 and 36 refer to natural and synthetic minerals having various industrially useful materials and chemical properties due to the unique pore structure present in the crystal.

When zeolites are produced in rocky areas or hollow spaces, they form large crystals that are transparent and beautiful enough to be used for ornamental purposes, but most natural and synthetic zeolites used in industry form fine crystalline aggregates.

Natural zeolites are silicate minerals containing a small amount of Na.K.Ca.Mg.Sr.Ba as a cation in chemical composition.

In the crystal structure, oxygen is shared by another tetrahedron, forming a three-dimensional network of reticulated silica. Quartz and feldspar minerals of the same structure form a very dense structure, whereas zeolite has a strict lattice structure in which large cavities of 2.3 ~ 7.5Å are formed in the structure.

The size of the cavity of the zeolite is Si. 4-12 oxygen bonded to Al is determined by the shape of the oxygen ring at the cavity inlet and the number of intervening oxygen, and it depends on the crystal structure of zeolite.

The type and size of the oxygen ring mobilized varies depending on the type, and thus the size of the cavity also varies. In the tetrahedron, cations often intervene in the structure to compensate for the charge deficiency caused by the partial substitution of Al + ³ transversely with Si + ⁴ .

Since these cations are present in structural cavities, they are easily replaced by other cations around them.

In addition, depending on the nature of the exchangeable cations that are electrostatically strongly charged in the cavity, it is contained in the water molecule (10-18%) cavity, which is a polar medium.

The cation exchange property of the zeolite means that the cations in the cavity easily ion exchange by simply washing with a solution of other cations. In general, the cation exchange capacity of the zeolite is about 200 ~ 400neg per 100g, which is more than twice the value of 100g (80 ~ 100neg) per 100g of cation exchange capacity of montmorilite used in similar applications.

Zeolites selectively exchange cations in addition to having the best cation exchange capacity among the minerals. Applications include soil and water modifiers, wastewater treatment, radioactive waste treatment, and cleaning aids for synthetic detergents.

The zeolite has adsorption and molecular sieve characteristics, and it contains a large amount of water (10-15%) in the cavity, but is easily dehydrated when heated to 200-300 ° C. for several hours.

Dehydrated zeolites selectively adsorb inorganic and organic molecules of suitable size and shape, resulting in excellent molecular sieve function that can separate each other from intermingled molecules. The selective adsorption characteristics of zeolites involved in molecular sieve function depend on the size and shape of the cavity.

In the case of zeolite A, the substitution with K has pores of 3 Å size, whereas the substitution with Na and Ca shows pore sizes of 4 Å and 5 각각, respectively. In addition, the selective adsorption capacity and propensity of the zeolite is governed not only by the characteristics of the pore structure but also by the shape, size, and polarity of the molecules acting thereon.

Applications include the use of desiccants for the dehydration of various gases, applications to specific gas generators (02, N2), and extraction of paraffins.

On the other hand, zeolites have dehydration and reabsorption properties because of the crystal structure, so-called non-calcite water exists in the mineral. The degree of inclusion of foreign substances in zeolites is very sensitive to not only the nature of the minerals and the nature of the cations, but also to the physical and chemical conditions around them, such as humidity and temperature. Inevitably endothermic and exothermic reactions are involved in the process of water in and out of the structure.

In other words, Xeon light can be used as an energy source in many ways.

When the mineral is gradually dehydrated when heated, it may be accompanied by structural changes such as crystal phase change or collapse.

In the application field of zeolite, the drying capacity and adsorption characteristics of zeolite are applied together, so that the drying process of natural gas and the catalytic efficiency of zeolite can be increased by hydrolyzing or replacing ammonium ion with exchangeable ions in the pore structure. To a zeolite having an OH- group.

Tio ₂ 35 Contact with sunlight and ozone causes photooxidation to oxidize harmful gases.

When it is put into sedimentation tank and aeration tank, it optimizes microbial production condition and shortens the cycle of nitrification and denitrification of organics, odors, and hardly decomposable substances mixed in wastewater, which shortens wastewater treatment time and improves wastewater treatment efficiency.
