[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an embodiment of a purification and deodorization system for contaminated mixed water according to the present invention, wherein 1 is a storage tank, 2 is a first tank, 3 is a second tank, 4 is a third tank, and 5 is sedimentation. Tanks, 6 to 8 are suction transfer pumps, 9 to 11 are drive pumps, 12 is a transfer pipe, 15 is a mecha-cera device, and 16 is a chlorine injection device.
[0013]
In FIG. 1, a storage tank 1 is a tank that stores manure from a barn as an object to be treated, and is appropriately supplied with mecha-cera water (ceramic catalyst water). For example, 4 times Mecera water 320t is supplied to and mixed with the slurry 80t. The mecha-cera device 15 is a water catalyst treatment device that generates mecha-cera water using a catalytic reaction obtained by containing functional ceramic particles and allowing an aqueous solution containing free chlorine to pass therethrough. An aqueous solution in which sodium hypochlorite or chlorine is injected by the chlorine injection device 16 as an aqueous solution is sent by a pump. Further, when alum is added in addition to sodium hypochlorite or chlorine, a higher treatment effect is obtained.
[0014]
The suction transfer pump 6 introduces the treated water from the third tank 4 by the drive pump 11 and injects it from the nozzle at a high pressure so that the contaminated mixed water in the storage tank 1 is discharged from the branch pipe provided on the downstream side of the first tank. 2 is a suction transfer means having a venturi structure for suction transfer to 2. The mecha-cera water may be directly supplied to the storage tank 1 as described above, but may be supplied in the middle of the transfer pipe 12 (suction line) as shown. If it does in this way, the MechaCera water and the contaminated mixed water sucked will be mixed very efficiently.
[0015]
The contaminated mixed water transferred to the first tank 2 is further transferred sequentially to the second tank 3 and the third tank 4. Then, the mecha-cera water is supplied to the second tank 3 and the third tank 4, respectively, and the contaminated mixed water is efficiently mixed and agitated by the suction transfer pumps 7 and 8. The suction transfer pumps 7 and 8 arranged in the second tank 3 and the third tank 4 are converted to high-pressure water by the drive pumps 9 and 10 and injected from the nozzles to the downstream side thereof. MechaCera water is sucked from the provided branch pipe, mixed into the contaminated mixed water, and stirred.
[0016]
The contaminated mixed water finally transferred to the third tank 4 is transferred to the settling tank 5 and subjected to precipitation treatment, the supernatant water is drained, and the precipitate is carried out. For livestock manure, as shown in the figure, the slurry 80t is supplied with 320t of Mekasera water, mixed and stirred in the 400t first tank 2 to the third tank 4, and the contaminated mixed water is transferred to the settling tank 5 for precipitation. If it processes, the processing of 35 t / h will be attained in the sedimentation tank 5. FIG.
[0017]
As described above, since the drive pumps 9 to 11 are all disposed in the second tank 3 and the third tank 4 and introduce water therein to the suction transfer pumps 6 to 8, a submersible pump is used. Among them, the drive pump 11 recycles and uses the water in the agitation processing tank 4 for the suction transfer pump 6 that sucks and transfers the contaminated mixed water in the storage tank 1 to the agitation processing tank 2. Further, the water supplied to the water supply unit of the mecha-cera device 15 may be used by recycling the waste water from the settling tank 5.
[0018]
For example, a mechanism having the following configuration is used for the mecha-cera device 15 (see, for example, Japanese Patent No. 3074266). There is an exhaust unit near the ceiling, an exhaust fan, a water supply unit and a watering nozzle near the bottom, an air supply unit and a drainage unit near the bottom, and a basket containing a mixture of multiple functional ceramic particles inside. It consists of processing tanks arranged in multiple stages. Then, a sodium hypochlorite aqueous solution having a concentration of about 1 to 3 ppm in which sodium hypochlorite (NaClO) is injected by the chlorine injection device 16 from the water supply unit is supplied to the watering nozzle and introduced into the MechaCera device from above. From the drainage part, mecha-cera water that has been showered with a watering nozzle and produced by catalytic action when passing through the functional ceramic particles is taken out. Further, for example, a malodorous component-containing gas or other gas, gas such as air is supplied from the air supply unit through the valve, and is introduced into the mecha-cera water stored in the mecha-cera device 15 from the bottom, from the exhaust unit, Deodorized and purified gas is sent by an exhaust fan and exhausted through a valve when passing through a plurality of functional ceramic particles and mecha-cera water.
[0019]
Conventionally, iron oxides used industrially, such as iron raw materials, abrasives, and ceramics, are iron trioxide (Fe ₃ O ₄ ). It is well known that it is used as a far-infrared ceramic because it is good. On the other hand, ferric oxide (Fe ₂ O ₃ ) is used as a glaze for ceramics and glazes. The functional ceramic particles of this embodiment contain the latter ferric oxide, use a resin or glass as a binder, and combine and sinter at least a plurality of metal oxides containing ferric oxide. A mixture of a plurality of types of granules.
[0020]
In the mecha-cera device 15, for example, a plurality of types of particles having different component concentrations composed of a first particle, a second particle, and a third particle are mixed and accommodated in the basket as functional ceramic particles. It is arranged to be detachable and replaceable in several stages. Examples of each of these granules are as follows. Each granule was obtained by mixing and kneading each raw material at a predetermined ratio, kneading and granulating, for example, at 12O <0> C for 12 hours, and then firing at 1150 <0> C to 1600 <0> C for 24 hours. The first particles are spheres of 25φ and sintered with a combination of metal oxides including ferric oxide, molybdenum, cobalt, titanium, magnesium, aluminum, potassium, zirconium, and silicon. The body is a 15φ sphere, which is sintered by combining metal oxides including ferric oxide, manganese, cobalt, titanium, magnesium, aluminum, potassium, zirconium, and silicon. The third particle is a 15φ sphere. The metal oxide containing aluminum oxide, zirconia, diatomaceous earth, and barium titanate was combined and sintered. When the total weight is 25 kg, the breakdown is, for example, the ratio of the first and second particles to the third particle is 95: 5, and the ratio of the first particles to the second particles. Was 7 to 3. That is, the first granule was about 16.525 kg, the second granule was 7.125 kg, and the third granule was 1.250 kg.
[0021]
The mixing ratio of each raw material was as follows: the first particles were Al ₂ O ₃ : 13.3, Fe ₂ O ₃ : 19.0, TiO ₂ : 20.0, MgO: 4.0, K ₂ O: 0 .7, ZrO ₂ : 5.0, CoO: 15.0, SiO ₂ : 11.0, MoO ₂ : 12.0, and the second particles were Al ₂ O ₃ : 26.5, Fe ₂ O ₃ : 21.2, TiO ₂ : 5.0, MgO: 4.2, K ₂ O: 0.7, ZrO ₂ : 5.0, MnO: 5.0, CoO: 7.3, SiO ₂ : 25 1. The third granule is made of celmen, silica, kaolin and clay as basic raw materials, ZrO ₂ : 5.0, CuO: 10.0, Al ₂ O ₃ : 10.0, BaTiO ₃ : 20. 0, SiO ₂ : 38.0.
[0022]
Furthermore, these functional ceramic particles can improve the efficiency of the ion reaction by controlling the component concentration and changing the atomic percentage, and the first particles have a particularly significant effect on sterilization and deodorization. It was confirmed that the second granule has a remarkable effect on the oil decomposition and sterilization action, and the third granule has a remarkable effect on the oil decomposition action. In addition, when the first particles and the second particles are mixed, the first particles and the second particles react with each other because the component concentrations are different, and the efficiency of ion generation is high. Furthermore, it has been proved that oil decomposition further proceeds by adding a small amount of the third particles. Moreover, the third granule has a strong coagulation action, forms molecules in a floc form, and has an action of making the oil component hydrophilic and lipophilic. Therefore, many effects of increasing the sludge settling speed have been confirmed in the wastewater treatment plant. In other words, the function of organic decomposition is improved, which contributes to the improvement of water quality and leads to further improvement of the deodorizing effect by removing the oxidized odor of oil. This is due to many years of experience in functional ceramic research and repeated tests, and this experience value determines the ratio criteria for each granule by applying it to deodorization and water quality improvement.
[0023]
Therefore, by controlling the component concentration and changing the mixing ratio of the first to third particles, the effect according to the processing purpose can be enhanced. For example, there are a lot of ammonia, hydrogen sulfide, nitrogen, phosphorous, etc. in the drainage of livestock industry such as pig farming, agricultural village drainage and general household wastewater, and the deodorizing effect is particularly required. In addition, there are many oils, nitrogen, phosphorous, etc. for factory wastewater including food factory wastewater, canteens, and restaurant wastewater, and the effect of oil decomposition is particularly required. The mixing ratio of the first to third particles is set according to each such request.
[0024]
The catalytic action by the functional ceramic is a technique using a catalytic reaction obtained by bringing an aqueous solution containing free chlorine into contact with the functional ceramic. Since NaClO is usually an alkaline solution, ClO ⁻ (hypochlorite ion) is stable.
[0025]
[Chemical 1]
NaClO → Na ⁺ + ClO ⁻
When this is added to the treated water, it is diluted to become a neutral solution, and thus the reaction proceeds as follows.
[0026]
[Chemical 2]
H ⁺ + ClO ⁻ → HClO
Na ^{+ +} OH ^- → NaOH
Further, HClO (hypochlorous acid) is decomposed as follows to generate nascent oxygen.
[0027]
[Chemical formula 3]
HClO → HCl + [O]
Hypochlorous acid (HClO) is more than 300 times more oxidizing than hypochlorite ion (ClO ⁻ ), and [O] in [Chemical Formula 3] is nascent oxygen with a strong oxidizing action. It is.
[0028]
This reaction is relatively slow, and when it is brought into contact with the functional ceramic, oxygen in the nascent stage is quickly generated. Therefore, its strong oxidizing action is effectively utilized, and an excellent effect on deodorization and the like is exhibited.
[0029]
It is well known that when sodium hypochlorite solution is dissolved in water as described above, hypochlorous acid (HClO) is generated and exerts a strong oxidizing function. It is also known that it is activated by light (ultraviolet rays) to be in a highly reactive state called a radical, and its oxidizing power is increased. Further, Fe ₂ O _{3 and the} like are included, and it is presumed that hydroxy radicals (HO · radicals) are generated by these energy actions.
[0030]
Next, operations such as deodorization and sterilization will be described. Among the decaying odors and excretion odors of living organisms, for example, skatole (3-methylindole) is the main component of unpleasant odors in public toilets, but it has weak basicity due to the functional group of -NH- ]
2C ₉ H ₉ N + HCl → 2C ₉ H ₉ N · HCl
It reacts with hydrochloric acid to produce skatole hydrochloride. This amine salt is odorless and soluble. Ammonia, which is a component of excretion odor, is combined with hypochlorous acid.
2NH ₄ ⁺ + 3HClO → N ₂ + 3H ₂ O + 5H ⁺ + 3Cl ⁻
The ammonia is decomposed and brominated free. Also,
[Chemical 6]
Cl ₂ + H ₂ O → HClO + H ⁺ + Cl ⁻
HClO ← → H ⁺ + ClO ⁻
When ammonia or an amine is present in the water by the reaction, it combines with chlorine to produce chloreramine (NH ₂ Cl). When chlorine is injected into ammonia-containing water, residual chlorine (free chlorine that has not become Cl) gradually increases, but at some point it begins to decrease rapidly, reaches a minimum point, and then increases rapidly. This point is called a discontinuous point, which is the point at which reducing substances such as ammonia disappear, and the amount of chlorine added so far is called the chlorine demand. The free chlorine present in the wastewater is the total of the three of Cl ₂ , HClO, and ClO, and the effective free chlorine is the total of HClO and ClO, combined with ammonia, amine, etc. as a nitrogen compound in the combined residual chlorine water. There is chlorine. Furthermore, hydrogen sulfide dissolves in water, but its dissociation is slight, reacts with sodium hydroxide and hypochlorous acid, becomes sulfur, and is not brominated.
[0031]
[Chemical 7]
H ₂ S + NaOH → NaHS + H ₂ O
NaHS + NaOH → Na ₂ S + H ₂ O
Na ₂ S + 4NaOCl → Na ₂ SO ₄ + 4NaCl
Na ₂ S + NaOCl + H ₂ O → NaCl + NaOH + S
Hydrogen sulfide is generated by the action of sulfate-reducing bacteria in the decay of proteins containing sulfur and in an anaerobic environment, but the redox potential (ORP) and dissolved oxygen concentration are higher than those of conventional treatment systems due to the supply of Mekasera water. It has been confirmed that (DO) shows a high value. Therefore, in addition to the oxidation reaction of [Chemical Formula 7], the anaerobic state is relaxed, and as a result, the generation of hydrogen sulfide is also suppressed.
[0032]
Furthermore, when MechaCera water is supplied, oxidation (nitrification) proceeds more than usual in the initial stage, so that ammonia nitrogen (NH ₄ -N) becomes nitrite nitrogen (NO ₂ -N), nitrate nitrogen (NO _3). -N), and the organic substance and nitrate nitrogen (NO ₃ -N) react with each other and are diffused into the air as nitrogen gas (N ₂ ), and the effect of denitrification also appears.
[0033]
[Chemical 8]
5CH ₃ OH + 6NO ₃ + 6H ⁺ → 5CO ₂ + 3N ₂ + 13H ₂ O
The component of the compound called red bump and red rust deposited inside the water pipe that has been used for a long time is mainly iron hydroxide Fe (OH) ₃ , in addition to calcium carbonate CaCO ₃ , magnesium carbonate MgCO ₃ , iron oxide Fe ₂ O ₃ and Fe ₃ O ₄ or the like. In Mekasera water, bimolecular chlorine Cl ₂ decreases, and HCl HCl and hypochlorous acid HClO are produced.
[Chemical 9]
Fe (OH) ₃ + 3HCl → FeCl ₃ + 3H ₂ O
CaCO ₃ + 2HCl → CaCl ₂ + H ₂ CO ₃
The Fe (OH) ₃ is changed to soluble FeCl ₃ and the CaCO ₃ is changed to soluble CaCl ₂ to dissolve the red cob.
[0034]
In wastewater treatment with microorganisms, by utilizing aerobic microorganisms that live in the presence of enzymes (soluble enzyme = DO),
[Chemical Formula 10]
(Aerobic oxidation)
Organic matter (C _x H _y O _z ) + O ₂ + aerobic microorganisms → CO ₂ + H ₂ O + activity energy of microorganisms (growth of microorganisms)
Organics _{(C x H y O z)} + N Compound + O ₂ + aerobic microorganisms → CO ₂ + H ₂ O + energy (endothermic reaction)
It reacts like this, and organic matter is oxidatively decomposed and used for the activity energy of microorganisms and the growth of organisms. Therefore, since the organic matter is oxidized to become a carbide, the organic matter becomes a carbonized solid, and further, the amount of sludge that is pulverized and carried out from the sludge concentration storage tank can be reduced.
[0035]
As described above, malodorous components such as reducing ammonia, methyl mercaptan, hydrogen sulfide, methyl sulfide, methyl dioxide, and acetaldehyde are deodorized by reacting with the nascent oxygen and changing to soluble or odorless compounds. In order to oxidatively decompose the oil and produce a surface-active effect and promote the emulsion phenomenon, the n-Hex extract material is decomposed and reduced. In addition, because of the improvement of the microbial environment, the activation of useful microorganisms, etc., because the generation of malodorous components such as ammonia and hydrogen sulfide is reduced, the deodorizing effect appears as a result, and useful microorganisms are activated. Increases sewage treatment capacity, contributes to water quality improvement, and reduces BOD, SS, n-Hex.
[0036]
FIG. 2 is a view showing another embodiment of the purification and deodorization system for contaminated mixed water according to the present invention, wherein 21 is a drive pump, 22 is a suction transfer pump, 23 and a hopper, 24 is a treatment tank, 25 is water supply, 26 indicates contaminated soil.
[0037]
In FIG. 2, the drive pump 21 introduces feed water 25 into the suction transfer pump 22 at a high pressure, and the hopper 23 introduces contaminated soil 26 into the branch pipe of the suction transfer pump 22. The suction transfer pump 22 sucks and transfers the contaminated soil 26 from the branch pipe through the hopper 23 to the treatment tank 24 by introducing high-pressure water supply 25 by the drive pump 21. Mekasera water is injected into the water supply 25 or while the contaminated soil 26 is being introduced from the hopper 23 into the branch pipe of the suction transfer pump 22. As a result, the contaminated soil 26 is mixed with the MechaCera water by the suction transfer pump 22, transferred to the treatment tank 24, and cleaned. When the cleaning effect in the treatment tank 24 is not sufficient, the cleaning effect can be enhanced by returning to the hopper 23 and cleaning again. Further, similarly to the embodiment shown in FIG. 1, the treatment tank 24 is composed of a plurality of tanks consisting of a first tank 2 to a third tank 4, and is configured to be sequentially transferred and washed while stirring with mecha-cera water. May be. Moreover, you may change the hopper 23 to the storage tank 1 similarly to embodiment shown in FIG. That is, in the embodiment of FIG. 1, manure can be replaced with contaminated soil as it is.
[0038]
Oil is generally divided into fat (triacylglyceride) and mineral oil (hydrocarbons, hydrocarbons, generally present in crude oil and used effectively in various situations). it can. Degradation of fat in the living body is first hydrolyzed to glycerol and fatty acid, and then the fatty long-chain fatty acid proceeds by a mechanism such as β oxidation. In general, a reactive species having a very high energy such as a hydroxyl radical imparts an oxygen atom to a molecule or a hydroxyl radical group to a molecule to create a clue for decomposition. In other words, when an oxygen atom is introduced, the reactivity of the molecule, that is, the substance increases, the decomposition proceeds due to the metabolic function that the organism constantly has (general mechanism of fatty acid β-oxidation), and the water-soluble It is decomposed into acetic acid (which is acetyl CoA ester in the living body) and carbon dioxide, and is completely decomposed and purified (biremediation). Even in mineral oils that are not easily decomposed by this mechanism, if active oxygen such as hydroxy radicals is present even if the living body is not involved, the oil is first oxygenated or radicalized, and once such a clue is formed, The decomposition proceeds in a chain as a general radical decomposition reaction.
[0039]
As mentioned above, when the aqueous solution infused with sodium hypochlorite or chlorine is added to the functional ceramic granules, for example, as shown in the livestock wastewater treatment test results in [Table 1] It has been confirmed that the effect is further improved, and it is confirmed that a considerable effect can be obtained only by the alum treatment, not the catalyst water that is brought into contact with the functional ceramic particles as shown in the results of the fishery processing test. Has been.

[0041]
In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, in the above-described embodiment, the configuration in which the three-stage tanks are sequentially transferred while mixing and stirring is shown. However, the number of tanks may be appropriately changed according to the object to be processed and the processing effect. . Further, in the above embodiment, it has been described as processing livestock manure, but not only livestock manure, but also various polluted wastewater, waste oil (grease wrap) and other waste liquids, as well as the above contaminated soil. It can also be applied to cleaning, deodorization, sludge reduction, and water quality improvement. For example, boilers such as steel and electric power and other combustion devices burn fossil fuels such as petroleum and coal, which contain a relatively large amount of sulfur, so dust and sulfur oxides (SO ₂ , SO ₃ , SO _{x in} exhaust gas) etc.), in order to remove nitrogen oxides (NO _x etc.), with respect to exhaust gas from a boiler and other combustion apparatus, and denitration by denitration apparatus, and dedusted by electrostatic precipitator further includes desulfurized by the desulfurizer The desulfurization drainage treatment is required for the drainage from the desulfurization apparatus because it is discharged from the chimney to the atmosphere. The present invention supplies ceramic catalyst water to such wastewater treatment, factory wastewater treatment, agricultural settlement wastewater treatment, and other wastewater / wastewater treatment, using the wastewater / wastewater as an object to be treated, and includes the ceramic catalyst water. A similar effect can be obtained by treating the contaminated mixed water.
[0042]
