Description

  The present invention relates to a method for decomposing organic organic waste for decomposing and annihilating raw garbage, residual sludge, oil residue and other organic waste, and a microbial activator used in the method.

  2. Description of the Related Art Conventionally, two types of treatment methods, a heat treatment type and a bio-treatment type, are mainly used as methods for treating garbage from restaurants and the like, and various methods for treating garbage are known.

  In the heat treatment type treatment method, waste containing moisture such as garbage is heated and the moisture in the waste is evaporated to dry the waste and reduce the volume (for example, patents) Reference 1).

  In the bio-processing type processing method, garbage is decomposed and reduced in volume by microorganisms by putting the garbage into a treatment tank containing a carrier carrying microorganisms and stirring (see, for example, Patent Document 2). ). The garbage treated by this bio-processing method can be composted and reused.

  On the other hand, in a bio-processing type treatment method, raw garbage is put into a treatment tank containing a carrier supporting microorganisms and stirred and sprinkled on the raw garbage to decompose the raw garbage into a liquid metamorphic product. A processing method is also known in which a liquid is discharged through a filter (see, for example, Patent Document 3).

  In addition, as a method of oxidizing and treating organic matter, an oxygen coil in the air is wound by winding an electromagnetic coil around the tip of a discharge tube that generates electrons from a discharge needle through which a high voltage is applied, and flowing air into the center of the coil. There is known a treatment method using an air electronic device that generates active oxygen species such as singlet oxygen by exciting the gas (see Patent Document 4). In this treatment method, organic substances contained in the atmosphere, water, and soil are decomposed by the oxidizing power of active oxygen generated by an air electronic device.

  However, in the heat treatment type processing method, not only a large amount of fuel is required to heat the waste containing water, but also the remaining waste even if it can be dried to reduce the volume to about 1/3. The disposal of things is a problem. Waste that remains after drying is finally incinerated or landfilled. Occurrence of odors and dioxins at the final disposal, sanitary and cost burden on the disposal site, and waste There are many problems such as the need for transportation.

  In addition, the method described in Patent Document 3 also has a weak ability to decompose microorganisms and cannot completely decompose garbage, so it is necessary to filter the liquid metabolite through a filter. Disposal becomes a problem as in the above method. Furthermore, the method described in Patent Document 3 has a problem that wastewater treatment is required because organic substances that could not be filtered by the filter are mixed in the discharged liquid.

Further, since these gelation inhibitors are decomposed by useful microorganisms in the treatment tank, the silicic acid solution is gelled to become porous, and has an effect of acting as a carrier for supporting the useful microorganisms.

  In addition, since the microbial activator of the present invention contains abundant inorganic salts that promote the growth of useful microorganisms by adding a magnesium aqueous solution, the microorganisms are further promoted to be useful and activated. There is an effect that can be maintained.

  In addition, the microbial activator of the present invention can be adjusted to a pH value at which useful microorganisms are activated and proliferate in the treatment tank by adding calcium hydroxide to adjust the pH, and the useful microorganisms Calcium can be supplied to promote growth and activate useful microorganisms. In addition, since the microbial activator of the present invention can maintain the temperature in the treatment tank by the heat of hydration of calcium hydroxide, a heat source such as a heater becomes unnecessary, and the treatment cost of organic waste is greatly reduced.

  The stirring member 2 is provided at a tip of each of the stirring shafts 22 provided in the processing tank 1 so as to be rotatable, a plurality of stirring arms 22 provided radially on the stirring shaft 21, and the stirring arms 22. It consists of a stirring claw 23. As shown in FIGS. 2 and 3, the agitation arm 22 is erected at a constant interval in the axial direction of the agitation shaft 21 and shifted by 120 ° in the direction around the axis of the agitation shaft 21. The stirring claw 23 has a V-shaped cross section that is open in the rotational direction, and is formed so that the carrier and the organic waste that are accommodated in the treatment tank 1 can be stirred and mixed.

  A scraper member 23 a is provided at the tip of the stirring claw 23 to abut against the inner peripheral surface of the processing tank 1 and scrape organic wastes attached to the inner peripheral surface. The scraper member 23a includes a plate member disposed at the tip of the stirring claw 23 in parallel with the stirring shaft 21, and a coil spring member attached to the plate member. In the scraper member 23a, an elastic coil spring member is brought into contact with the inner peripheral surface of the treatment tank 1, and organic waste adhering to the inner peripheral surface can be surely scraped off.

  In the embodiment, in the stirring member 2, two sets of three stirring arms 22 erected in the direction around the stirring shaft 21 at intervals of 120 ° are arranged in the axial direction of the stirring shaft 21. The width of the scraper member 23a is larger than the axial interval of the stirring arm 22, and the scraper member 23a removes organic waste from the entire inner peripheral surface of the treatment tank 1 by rotating the stirring shaft 21 once. It can be scraped off.

  In FIGS. 1 and 3, reference numeral 20 denotes a drive mechanism, which is configured so that the stirring member 2 can be rotationally driven. The drive mechanism 20 includes a motor 24, a drive sprocket 25 provided on the drive shaft of the motor 24, a driven sprocket 27 provided on the stirring shaft 21, and an endless chain 26 that transmits the rotational driving force of the drive sprocket 25 to the driven sprocket 27.

  In the case of the method of an Example, 3-10 rpm is preferable and, as for the rotation speed of the stirring member 2, 5 rpm is the most preferable. When the rotation speed of the agitating member 2 is 20 rpm or more, the contents in the processing tank 1 are cooled by the air sent by the blowing means 4, the temperature in the processing tank 1 is lowered, and the organic waste is decomposed by useful microorganisms. This is not preferable because the capacity is lowered. In addition, when the rotational speed of the stirring member 2 is 1 rpm or less, stirring of the carrier and organic waste stored in the treatment tank 1 becomes insufficient, and the ability of decomposing organic waste by useful microorganisms decreases. It is not preferable.

  The treatment tank 1 and the stirring member 2 are not limited to the configurations shown in FIGS. 1 to 3 and can contain a carrier supporting microorganisms, and stir and mix the carrier and organic waste. It is possible to use various types of processing tanks and stirring members.

  In the embodiment shown in FIG. 1, the blower means 4 is disposed in the longitudinal direction of the tank in the treatment tank 1, a blower path 41 for sending air into the treatment tank 1, a blower 42 provided in the blower path 41. And an air supply pipe 44. As shown in FIGS. 2 and 3, the air supply pipe 44 is disposed at the lower part of the processing tank 1 so as to protrude toward the outside of the tank. Air supply ports 45 are provided on the side surfaces of the air supply pipe 44 at regular intervals so that the air can be uniformly supplied into the processing tank 1 in the direction of rotation of the stirring member 2. A blower passage 41 is connected to the center of the air supply pipe 44, and air is sent into the air supply pipe 44 by the blower 42.

  In the embodiment, the air blowing means 4 includes a circulation path 43 that takes out air from the upper part of the processing tank 1 and sends it to the air blowing path 41 to circulate all or part of the air sent into the processing tank 1. The air blowing means 4 circulates all or a part of the air sent into the processing tank 1 to prevent the temperature in the processing tank 1 from decreasing, and the ability to decompose organic waste by useful microorganisms decreases. Is preventing. Moreover, the ventilation means 4 is provided with the external air taking-in means, and can keep the inside of the processing tank 1 in an aerobic state by taking in external air. Note that the air blowing means 4 may be configured without the circulation path 43.

  In the embodiment, the organic waste decomposition treatment method carries in the treatment tank 1 one or more microorganisms selected from the group of photosynthetic bacteria, Bacillus bacteria, lactic acid bacteria, and yeast as useful microorganisms. It is housed together with a carrier. These useful microorganisms have a high ability of decomposing organic matter, and are actively carried by being carried on a carrier accommodated in the treatment tank 1 and can decompose organic waste.

  The photosynthetic bacteria stored in the treatment tank 1 are preferably red non-sulfur bacteria that can act under aerobic conditions, preferring to decompose organic substances such as fats and oils and starch, and also decomposing hydrogen sulfide and ammonia that cause odors. Odor can be eliminated. Moreover, since the treatment tank 1 is fed with air by the blowing means 4, other aerobic microorganisms can be added to decompose the organic matter.

In the method for decomposing organic waste according to the embodiment, rice husk is accommodated in the treatment tank 1 as a carrier. The rice husk contains abundant silicon dioxide (SiO ₂ ) and a small amount of an alkali element, is suitable as a carrier in shape and size, and can activate useful microorganisms. In particular, Bacillus bacteria are activated by silicon and are excellent in degradability of proteins, starch, fats and oils, ammonia and the like, and it is preferable to use rice husk as a carrier. In addition, the support | carrier accommodated in the processing tank 1 is not restricted to a rice husk, The porous agent formed with the wood chip material processed into the appropriate magnitude | size, and the raw material which does not prevent the proliferation of microorganisms is used. You can also.

  Before the useful microorganisms are accommodated in the treatment tank 1, it is preferable that the microorganisms are cultivated with an organic material equivalent to the organic waste to be treated. Thereby, microorganisms suitable for the decomposition of the organic waste to be treated become the dominant species, and the treatment time of the organic waste can be shortened.

  In the embodiment, the organic waste decomposition treatment method contains a microbial activator for activating useful microorganisms in the treatment tank 1. In the examples, a silicon sol obtained by dissolving a silicon-containing solute obtained by mixing and heat-treating a silicon-containing substance and an alkaline substance in an acid solvent is used as the microbial activator.

The silicon-containing material is a natural earth or rock containing a silicon compound such as silicon dioxide (SiO ₂ ), or a processed product containing them. The silicon-containing substance preferably contains iron that causes a Fenton reaction, and preferably contains magnesium in order to promote the growth of useful microorganisms such as Bacillus bacteria. As the silicon-containing material, for example, as shown in Table 1, Ibube white clay (earth in Okinawa Ibube region) containing a high content of silicon dioxide and containing iron oxide (FeO ₃ ) can be used. .

The alkaline substance is mixed in order to change the silicon-containing substance into acid solubility. In the embodiment, calcium carbonate (CaCO ₃ ) or lime is mixed as the alkaline substance with the silicon-containing substance and heat-treated. Thereby, the generated silicon-containing solute becomes powdery, so that solubility in an acid solvent is improved and calcium, which is an inorganic salt that promotes the growth of useful microorganisms, can be included. This heat treatment is preferably performed at a temperature not higher than the thermal melting point of the silicon-containing material, because if it is performed at a temperature higher than the thermal melting point of the silicon-containing material, it becomes glassy and its solubility is lowered. When the silicon-containing material is Ibube Shirato (earth in Ibube, Okinawa Prefecture) shown in Table 1, it is performed at an arbitrary temperature of about 1300 ° C. or lower, which is the thermal melting point of Ibube Shirato, and the thermal melting point. It is preferable to perform heat treatment at 1150 to 1250 ° C., which is close to.

  Since the silicon-containing solute has excellent acid solubility by heat treatment at a temperature below the thermal melting point of the silicon-containing substance, it is dissolved in an acid solvent to become a stable silicon sol, and is stored in the treatment tank 1. It can be easily mixed with carriers and organic waste.

  Further, as the silicon-containing solute, a product obtained by mixing and heat-treating a silicon-containing substance and an alkaline substance such as cement, an intermediate product of cement, blast furnace slag, and coal ash can be used. Although these silicon-containing solutes are inferior in acid solubility as compared with silicon-containing solutes that have been heat-treated at a temperature lower than the thermal melting point of the silicon-containing material, they can activate useful microorganisms. In particular, as shown in Table 1, ordinary cement is rich in magnesium and calcium, which are inorganic salts that promote the growth of useful microorganisms. Therefore, it is preferable to use ordinary cement as a silicon-containing solute. The silicon-containing solute may be used by mixing two or more substances selected from the group consisting of cement, cement intermediates, blast furnace slag, and coal ash.

  Moreover, what baked the carbide slurry which has calcium hydroxide as a main component and contains silicon dioxide at 800 to 1300 degreeC can also be used for a silicon-containing solute.

In the examples, hydrochloric acid (HCl) was used as the acid solvent. Hydrochloric acid (HCl) is highly soluble in calcium and, when neutralized, becomes calcium chloride (CaCl ₂ ) and is safe and non-toxic. Therefore, hydrochloric acid is preferably used as the acid solvent. Further, since the solubility of silicon with respect to the acid concentration is constant and the density of the silicon sol dispersed in the liquid volume can only be kept stable in a constant water gap, diluted hydrochloric acid diluted with hydrochloric acid as an acid solvent. In particular, it is preferable to use dilute hydrochloric acid diluted 3 to 7 times. The acid solvent is not limited to hydrochloric acid (HCl), and other acid solutions can also be used.

The acid solvent contains one or more gelation inhibitors selected from the group consisting of acetic acid (C ₂ H ₄ O ₂ ), ammonium acetate (CH ₃ COONH ₄ ), and ammonium chloride (NH ₄ Cl). Preferably there is. The acid solvent contains acetic acid (C ₂ H ₄ O ₂ ) as a gelation inhibitor, so that the drop amount of acetic acid is adjusted by adjusting the acetic acid pH buffering action and the convergence of the sol and colloid. Gelation can be suppressed. In addition, since organic acids such as acetic acid are excellent substrates for red bacteria, the use of acetic acid as a gelation inhibitor can further activate useful microorganisms.

  When the microbial activator is accommodated in the treatment tank 1, the gelation inhibitor is decomposed by useful microorganisms, so that the silicon sol is gelled to become porous and also acts as a carrier for supporting the useful microorganisms. be able to. In addition, gelation of the silicon sol can be suppressed similarly to acetic acid by a mixed acid obtained by adding ammonium acetate or ammonium chloride to dilute hydrochloric acid.

  Moreover, it is preferable to add magnesium aqueous solution to the microbial activator. Magnesium, together with calcium added as an alkaline substance, is an inorganic salt that promotes the growth of useful microorganisms, so it can promote further growth of useful microorganisms and maintain the activated state of useful microorganisms.

In the embodiment, the organic waste decomposition treatment method contains calcium hydroxide (Ca (OH) ₂ ) as a pH adjuster in the treatment tank 1. In this organic waste decomposition treatment method, the temperature in the treatment tank 1 can be maintained at about 40 to 50 ° C. by the heat of hydration of calcium hydroxide. Therefore, the organic waste extinguishing apparatus 10 does not require a heater or the like for maintaining the temperature in the processing tank 1, and can reduce processing costs. As the pH adjuster, an alkaline agent such as caustic soda (NaOH), calcium carbonate (CaCO ₃ ), or lime can be used, but calcium hydroxide is used because heat of hydration can be used. It is preferable.

  In the embodiment, the active oxygen supply means 3 is installed in the blower passage 41 and configured to supply active oxygen into the treatment tank 1. The active oxygen supply unit 3 includes a blower passage 41 for sending air into the treatment tank 1, a magnetic field generator for generating a magnetic field in the blower passage 41, and an electron generator for emitting electrons into the blower passage 41.

  As shown in FIG. 4, the air passage 41 is branched into two on the downstream side of the blower 42. The active oxygen supply means 3 is installed in both the branched air passages 41 and 41 adjacent to the blower 42. Further, the discharge side of the active oxygen supply means 3 is connected to an air supply pipe 44 disposed in the processing tank 1 so that active oxygen having a short life can be efficiently supplied into the processing tank 1. .

  As shown in FIGS. 4 and 5, the magnetic field generating means includes an electromagnetic coil 33 wound around the air supply pipe 32 a forming the air passage 41 in a direction perpendicular to the air blowing direction along the circumferential direction, and an electromagnetic coil. And a current supply mechanism 37 for supplying a direct current to 33. The current supply mechanism 37 supplies a direct current to the electromagnetic coil 33 in such a direction as to generate a static magnetic field in the same direction as the air blowing direction (N on the leeward side and S pole on the leeward side). In the embodiment, the current supply mechanism 37 supplies a DC current of 9V-3A to the electromagnetic coil 33. Note that the magnetic field generated by the magnetic field generating means can be the south pole on the leeward side and the north pole on the leeward side.

  The air supply pipe 32a is formed of a non-conductive synthetic resin, and the inner periphery of the air supply pipe 32a around which the electromagnetic coil 33 is wound has a heat conductive property such as copper, aluminum, tin, brass, zinc, and titanium. A nonmagnetic tube 31 made of a good nonmagnetic metal is provided. The nonmagnetic tube 31 can heat the air supplied to the processing tank 1 while suppressing overheating of the electromagnetic coil 33 by heat radiation. In the embodiment, the nonmagnetic tube 31 is made of aluminum or titanium.

  A temperature sensor 35 is disposed on the outer periphery of the electromagnetic coil 33. The temperature sensor 35 cuts off the current of the current supply mechanism 37 when the temperature of the electromagnetic coil 33 rises above a predetermined temperature. In the embodiment, the temperature sensor 35 cuts off the current of the current supply mechanism 37 at 70 ° C. or higher to prevent the electromagnetic coil 33 from overheating.

  The electron generating means includes a discharge electrode 32b and a counter electrode 32c provided in the air supply tube 32a so as to face each other in the blowing direction. The discharge electrode 32b is composed of a rod-like electrode arranged perpendicular to the blowing direction, and is installed upstream of the magnetic field generating means. The counter electrode 32c is made of a titanium oxide, is made of a rod-like body arranged in parallel with the discharge electrode 32b, and is installed adjacent to the downstream side of the magnetic field generating means. The discharge electrode 32b is connected to a high voltage power supply 38, and the counter electrode 32c is grounded.

  The high voltage power source 38 applies a 30 kV DC voltage between the discharge electrode 32b and the counter electrode 32c, and emits electrons in the same direction as the blowing direction (the same direction as the static magnetic field) from the discharge electrode 32b to the counter electrode 32c. It is configured to be able to be made. An insulator 34 is inserted around the discharge electrode 32b to prevent leakage from the discharge electrode 32b. Since the electron generating means does not generate enough electrons when the voltage between the discharge electrode 32b and the counter electrode 32c is low, it is preferable that the high voltage power supply 38 can apply a voltage of 5 kV or more between the discharge electrode 32b and the counter electrode 32c. .

  The discharge electrode 32b can also be formed by a discharge needle in which the needle tip is disposed in the air supply tube 32a in the blowing direction. The counter electrode 32c is preferably formed of titanium oxide because it can promote the generation of active oxygen by catalytic action, but can also be formed of copper or a copper alloy. It can also be formed of a material.

  Electrons radiated from the discharge electrode 32b toward the counter electrode 32c are arranged in a constant direction by the static magnetic field in the electromagnetic coil 33, and spiral movement is caused by a shift between the static magnetic field and the electron movement direction. Proceed along the magnetic field lines of the static magnetic field.

The blower 42 is configured to send a large amount of air to the active oxygen supply means 3 through the air blowing path 41 and to blow superoxide anions (O ₂ ⁻ ) generated by the active oxygen supply means 3 into the treatment tank 1. The oxygen molecules sent into the electromagnetic coil 33 are ground state triplet oxygen ( ³ O ₂ ), and have two unpaired electrons. In the triplet oxygen ( ³ O ₂ ), the electron spin direction in the molecule is aligned in a constant direction by the static magnetic field in the electromagnetic coil 33. Then, unpaired electrons of triplet oxygen ^{(3 O} _2), when the spin direction is changed by a magnetic field electrons spiral motion occurs, is excited to singlet oxygen ^{(1 O} _2). Since this singlet oxygen ( ¹ O ₂ ) is an oxygen molecule to which electrons are easily added, the direction of the electron spin is aligned, and the electrons in spiral motion are added to generate a superoxide anion (O ₂ ⁻ ). can do.

As described above, the active oxygen supply means 3 uses the static magnetic field in the electromagnetic coil 33 to change the electron spin direction of electrons radiated into the air passage 41 and the electron spin direction of oxygen molecules passing through the air passage 41. It is possible to control and add an electron to the oxygen molecule to generate a superoxide anion (O ₂ ⁻ ) having a strong oxidizing power. The active oxygen supply means 3 supplies a direct current of about 1 to 3 A to the electromagnetic coil 33 and applies a high voltage of 5 kV or more to the discharge electrode 32 b to thereby singlet the ground state triplet oxygen ( ³ O ₂ ). Excited to the term state, an electron can be added to generate a superoxide anion (O ₂ ⁻ ).

In the illustrated embodiment, the active oxygen supply means 3 is provided inside a support frame 13 that supports the processing tank 1. Since the lifetime of the superoxide anion (O ₂ ⁻ ) is short, the active oxygen supply means 3 is preferably provided at a position close to the supply pipe 44.

  In the organic waste decomposition method of the example, the treatment tank 1 has an aqueous solution that supplies SOD-producing microorganisms that produce superoxide dismutase (hereinafter referred to as “SOD”) and metal ions that cause a Fenton reaction, It contains a metal or metal compound.

  The microorganism that can be used as the SOD-producing microorganism is not particularly limited as long as it can produce SOD. For example, a photosynthetic bacterium, particularly a red bacterium (Proteobacteria) is preferable in that it can supply more SOD and can decompose organic physical waste.

  Examples of red bacteria include alpha proteobacteria, beta proteobacteria, and gamma proteobacteria. Examples of Rhodopseudomonas, Rhodospirillum, Rhodobacter, and Ectothiorhodospira genus, especially Rhodobacter sphaeroacter Rdobacter R capsulatus, Rhodospirillum rubrum, Rhodopseudomonas palustris, Ectothiorhodospira shaposhnikovii (Ectothiorhodospira vacuolata), Ectothiorhodospira mobilis, Ectothiorhodospira halophila can be used.

  Examples of available strains include S, IL106, IFO12203, KA38, NR3, ATCC17023, NI17, NI20, P2, and MC9R for Rhodobacter sphaeroides, and MS9R for Rhodobacter capsulatus. For example, G-9BM and IFO3986 strains can be exemplified for Rhodospirillum rubrum, ATCC17001 strain, SA37 strain, NIV2 strain, and DIII4 strain can be exemplified for Rhodopseudomonas palustris, and Ectothiorhodospira shaposhnikovii (Ectothiorhodospira shaposhnikovlat) The ATCC 31751 strain can be exemplified, the Ectothiorhodospira mobilis can be exemplified by the NI8 strain, and the Ectothiorhodospira halophila can be exemplified by the H16 strain. Bets are possible. Moreover, as long as SOD is produced, one or more kinds of various microorganisms may be included, and a mixture of plural kinds may be used.

  Moreover, it is preferable that the processing tank 1 contains one or two or more auxiliary agents selected from the group of copper (Cu), zinc (Zn), and manganese (Mn). These adjuvants can assist SOD producing microorganisms to produce SOD. These adjuvants can be accommodated in the treatment tank 1 as compounds, and can also be contained in the treatment tank 1 by being included in a carrier or added to a microbial activator. In addition, SOD is not limited to what is supplied from the SOD production microbe accommodated in the processing tank 1 like an Example, It is also possible to store SOD directly in the processing tank 1. FIG.

The metal ions accommodated in the treatment tank 1 for causing the Fenton reaction are divalent iron ions (Fe ²⁺ ) and / or monovalent copper ions (Cu ⁺ ) because they have a strong force to cause the Fenton reaction. It is preferable. This metal ion can be supplied by accommodating a divalent iron compound or a monovalent copper compound in the treatment tank 1. Moreover, this metal ion can also be accommodated in the processing tank 1 as aqueous solution, and can also be contained in a microbial activator. Examples of divalent iron compounds include iron sulfate (II) [FeSO ₄ ], potassium hexacyanoferrate (II) (K ₄ [Fe (CN) ₆ ]), iron sulfide (II) [FeS], and the like. Can be mentioned.

SOD produced by the SOD-producing microorganism decomposes the superoxide anion (O ₂ ⁻ ) supplied from the active oxygen supply means 3 into hydrogen peroxide (H ₂ O ₂ ) and oxygen (O ₂ ). This hydrogen peroxide (H ₂ O ₂ ) is decomposed into a hydroxy radical (.OH) and a hydroxy ion (OH ⁻ ) by a reaction of the following formula by a divalent iron ion (Fe ²⁺ ) causing a Fenton reaction. .
H ₂ O ₂ + Fe ²⁺ → OH + OH ⁻ + Fe ³⁺ (Fenton reaction)

The trivalent iron ion (Fe ³⁺ ) generated from the divalent iron ion (Fe ²⁺ ) by the Fenton reaction is expressed by the following formula by the superoxide anion (O ₂ ⁻ ) supplied from the active oxygen supply means 3. By this reaction, it is reduced to divalent iron ions (Fe ²⁺ ). The reduced divalent iron ion (Fe ²⁺ ) can cause the Fenton reaction again.
O ₂ ⁻ + Fe ³⁺ → O ₂ + Fe ²⁺ (Haber-Weiss reaction)

This hydroxy radical (.OH) is a kind of active oxygen having the strongest oxidizing power, and can decompose all organic substances such as carbohydrates, proteins and lipids. The organic waste decomposition treatment method according to the present invention decomposes by generating in the treatment tank 1 hydroxy radicals (.OH) having a very strong oxidizing power and a short lifetime of 1/1 million seconds. Difficult organic waste can be reliably oxidatively decomposed. In addition, since superoxide anion (O ₂ ⁻ ) and other active oxygen remaining without being decomposed by SOD can also oxidize and decompose organic waste, this decomposition treatment method requires the decomposition time of organic waste. Can be greatly shortened.

  The method for decomposing organic waste according to the present invention can oxidize and decompose organic waste contained in the treatment tank 1 by active oxygen and subdivide it into the treatment tank 1. By decomposing with useful microorganisms including the contained SOD-producing microorganism, the organic waste can be reliably decomposed, and can be completely extinguished depending on the object to be treated.

  The deodorizing means 5 includes a deodorizing tower 51 for deodorizing the exhaust discharged from the treatment tank 1, an exhaust port 53 for discharging the exhaust deodorized by the deodorizing tower 51, and a drain 54. Exhaust gas discharged from the treatment tank 1 is guided to the deodorization tower 51 through the exhaust pipe 50. The deodorizing tower 51 contains a deodorizing agent such as activated carbon and a deodorizing liquid, and can deodorize exhaust gas sent from the exhaust pipe 50. An exhaust blower 52 is provided at the exhaust port 53 so that the exhaust gas deodorized by the deodorization tower 51 is discharged. The drain 54 is provided for discharging liquid such as moisture contained in the exhaust gas. Moreover, the deodorizing means 5 can also discharge directly from the exhaust pipe 50, when the exhaust from the processing tank 1 does not have an odor.

Next, the operation of the organic waste decomposition method according to the present invention will be described.
Since the organic waste extinguishing apparatus 10 used in the decomposition processing method of the present invention is small and consumes little power, it can be installed in a restaurant, a kitchen, etc., and processed at the place where the organic waste is generated. it can. Moreover, the organic waste extinguishing apparatus 10 can also be attached to the wastewater treatment facility to treat residual sludge discharged from the wastewater treatment facility.

  In the illustrated embodiment, the method for decomposing organic waste is one or more useful selected from the group consisting of a carrier supporting microorganisms, photosynthetic bacteria, Bacillus bacteria, lactic acid bacteria, and yeast in the treatment tank 1. Microorganisms and SOD producing microorganisms, microbial activators that activate these useful microorganisms, pH adjusters, and divalent iron ions that cause a Fenton reaction, depending on the treatment capacity of organic waste, respectively The necessary amount is accommodated.

  As shown in Table 2, the organic waste extinguishing apparatus 10 with a processing capacity of 15 kg / day is a useful microorganism in which a rice husk is 150 L (liter) as a carrier and a Bacillus bacterium is a dominant species in the treatment tank 1. 2 liters of the culture solution of the above, 2 liters of the culture solution of useful microorganisms that are dominant species of photosynthetic bacteria including red bacteria, which are SOD-producing microorganisms (20 liters diluted 10-fold), and 0.75 liters of the microbial activator ( 7.5L) diluted 10 times, 2 kg of calcium hydroxide (slaked lime) as a pH adjuster, and 0.30 L (20 mg of ferrous sulfate [ferrous sulfate] solution as divalent iron ions It is diluted 6 times and accommodated. Moreover, the decomposition | disassembly processing method of organic waste has accommodated in the processing tank 1 1 or 2 or more adjuvants chosen from the group of magnesium aqueous solution and copper, zinc, and manganese as needed. .

  In Examples, the photosynthetic bacteria accommodated in the treatment tank 1 are Rhodobacter sphaeroides S strain, IL106 strain, IFO12203 strain, KA38 strain, NR3 strain, ATCC17023 strain, NI17 strain, NI20 strain, P2 strain, MC9R strain, Rhodobacter capsulatus MS9R strain, Rhodospirillum rubrum G-9BM strain, IFO 3986 strain, Rhodopseudomonas palustris ATCC 17001 strain, SA37 strain, NIV2 strain, DIII4 strain, Ectothiorhodospira shaposhnikovii strain 1451 strain Epittothiorhodoc1 One or a plurality of types of photosynthetic bacteria selected from H16 strains of Ectothiorhodospira halophila are cultured.

  Moreover, the Bacillus genus bacteria accommodated in the processing tank 1 can use the 1 or 2 or more types which can decompose | disassemble organic substance, give organic substance equivalent to the organic waste used as a process target, and culture | cultivate. Therefore, the species suitable for the decomposition of the organic waste to be treated is regarded as the dominant species.

In an embodiment, microbial active agent contained in the processing bath 1 is normally dissolved cement into dilute hydrochloric acid (6.6% concentration) diluted in 5-fold, acetate as the gelling inhibitor (C ₂ H ₄ O ₂ ) Is added. This microbial activator makes a saturated solution of silicon sol and dilutes this saturated solution 10 times. Since acetic acid is a perfect substrate for red bacteria, it is preferable to add acetic acid to the microbial activator, but it is also possible to add ammonium acetate or ammonium chloride. Moreover, since it is not necessary for the microbial activator to maintain a complete sol state, it is possible to use a microbial activator that does not contain a gelation inhibitor such as acetic acid.

The calcium hydroxide accommodated in the treatment tank 1 can adjust the pH of the microbial activator and maintain the temperature in the treatment tank 1 by heat of hydration. In addition, calcium hydroxide (Ca (OH) ₂ ) generates calcium carbonate (CaCO ₃ ) and water (H ₂ O) by carbon dioxide (CO ₂ ) generated when organic substances are decomposed, and calcium carbonate is a useful microorganism. It is also a source of inorganic salts that promote the growth of

  The organic waste extinguishing apparatus 10 containing the substances and microorganisms shown in Table 2 inputs the organic waste into the treatment tank 1 from the input port 11, and decomposes the organic waste. In the method for decomposing and extinguishing organic waste according to the present invention, a collective amount of organic waste is introduced into the treatment tank 1 from the inlet 11 at a predetermined time interval. The organic waste introduced into the treatment tank 1 is subdivided into a size that allows the useful microorganisms to be easily decomposed by the active oxygen, so that the organic waste is decomposed by leaving a predetermined time interval for the introduction of the organic waste. Processing capacity is improved. It should be noted that organic waste that can be easily decomposed by useful microorganisms, such as leftover rice, can be continuously fed into the treatment tank 1 without leaving an interval.

  Since the rice husk accommodated in the treatment tank 1 as a carrier is decomposed and reduced by active oxygen and useful microorganisms, a reduced amount of rice husk is replenished in the treatment tank 1 according to the amount of reduction (for example, once a week). ing. Similarly, since the microbial activator and the like stored in the treatment tank 1 are consumed by useful microorganisms, the microbial activator corresponding to the reduced amount (for example, once a week), the pH adjuster and the mineral The processing tank 1 is replenished with the agent and the like. On the other hand, useful microorganisms contained in the treatment tank 1 can obtain necessary nutrients from organic wastes and microbial activators, and are propagated in the treatment tank 1, so that replenishment is not required for a long period of time. is there.

  The organic waste extinguishing apparatus 10 supplies the active oxygen generated by the active oxygen supply means 3 into the treatment tank 1 from the supply pipe 44 by the blowing force of the blower 42. The organic waste housed in the treatment tank 1 is oxidatively decomposed by active oxygen.

The active oxygen supply means 3 supplies active oxygen containing mainly a superoxide anion (O ₂ ⁻ ) into the treatment tank 1. The superoxide anion (O ₂ ⁻ ) supplied into the treatment tank 1 is decomposed into hydrogen peroxide (H ₂ O ₂ ) and oxygen (O ₂ ) by SOD produced by SOD producing microorganisms such as red bacteria. . This hydrogen peroxide (H ₂ O ₂ ) is decomposed into a hydroxy radical (.OH) and a hydroxy ion (OH ⁻ ) by a reaction of the following formula by a divalent iron ion (Fe ²⁺ ) causing a Fenton reaction. .
H ₂ O ₂ + Fe ²⁺ → OH + OH ⁻ + Fe ³⁺ (Fenton reaction)

This hydroxy radical (.OH) is a kind of active oxygen having the strongest oxidizing power, and can decompose all organic substances such as carbohydrates, proteins and lipids contained in organic waste. The superoxide anion (O ₂ ⁻ ) generates a hydroxy radical (.OH) by reaction with water (H ₂ O), but the reaction rate is slow and the amount produced is very small. In the present invention, hydrogen peroxide (H ₂ O ₂ ) is generated from a superoxide anion (O ₂ ⁻ ) by SOD, and further a hydroxy radical (.OH) is generated by a Fenton reaction. Was able to dramatically increase the supply.

  Organic waste that has been oxidatively decomposed by active oxygen and subdivided is further decomposed by useful microorganisms such as Bacillus bacteria and photosynthetic bacteria accommodated in the treatment tank 1, except for organic waste that is difficult to decompose. Almost disappears. Further, the organic waste remaining without being decomposed is taken in when the microbial activator gels to form a floc. The organic matter taken into the floc is oxidatively decomposed by hydroxy radicals (.OH) to form minute holes in the floc. In the hole formed in the floc, useful microorganisms settle, and further, organic substances are decomposed into a porous floc. This porous floc functions as a carrier for useful microorganisms. As described above, the method for decomposing organic waste according to the present invention enables the organic waste to be subdivided into sizes that can be easily decomposed by useful microorganisms by the oxidative decomposition action of active oxygen, and is useful activated by a microbial activator. Organic waste can be almost eliminated by microorganisms, and the remaining organic waste is taken into the floc and further decomposed. Can be decomposed.

  In the embodiment shown in FIG. 1, the organic waste decomposition method is to decompose waste containing persistent cellulose, grease trap sludge, residual sludge containing petroleum polymer flocculant, and the like. Became possible. When processing the hardly decomposable organic waste, the organic waste extinguishing apparatus 10 takes out the residue in the treatment tank 1 from the discharge port 12, and newly introduces this residue into the organic waste. By mixing them into the charging port 11 and charging them from the charging port 11, it is possible to reliably perform the decomposition process, and it is possible to reduce the waste that cannot be processed. With this method, the organic waste extinguishing apparatus 10 can decompose organic waste including plastic.

  In the embodiment shown in FIG. 1, the organic waste decomposition method can decompose food waste, bread crumbs, vegetables, fruits, cardboard paper, etc. in a short time, which is impossible or difficult in the prior art. Onion, citrus peel, okara, feces such as rabbits, oil canisters, and chicken pail can be decomposed.

  Table 3 shows experimental data obtained by decomposing organic waste (garbage) using the organic waste extinguishing apparatus 10 shown in FIG. The treatment tank 1 used was a garbage having a treatment capacity of 15 kg / day in the conventional garbage decomposition process using microorganisms.

  In Table 3, the horizontal axis represents time, the left vertical axis represents the weight in the treatment tank 1, and the right vertical axis represents the temperature in the treatment tank 1. As shown in Table 3, the organic waste is put into the treatment tank 1 four times a day. Of the four inputs, one is charged with about 20 kg of organic waste, and the remaining three times are charged with about 5 kg of organic waste.

  The temperature in the processing tank 1 changes between about 40 degreeC-50 degreeC. Table 3 shows that the weight (amount of organic waste) in the treatment tank 1 is greatly reduced when the temperature in the treatment tank 1 is drastically lowered. From this, the organic waste extinguishing apparatus 10 can grasp the input interval of the organic waste from the temperature change (temperature decrease) in the treatment tank 1.

  As shown in Table 3, the organic waste extinguishing apparatus 10 is charged with 35 to 37 kg / day of organic waste, which greatly exceeds the processing capacity (15 kg / day), but is charged. Organic waste is reliably decomposed. Moreover, the organic waste extinguishing apparatus 10 did not need to discharge the residue from the discharge port 12 with almost no residue that could not be decomposed even when operated for more than one month. In other words, the organic waste decomposition method according to the present invention can greatly reduce the amount of waste that has been a problem because about 30% of the input amount is discharged because it cannot be processed in the prior art. It was. In the embodiment, the organic waste decomposition method can almost completely decompose the organic waste except for the hardly-decomposable organic waste, and can eliminate the emission.

  As shown in Table 3, the organic waste extinguishing apparatus 10 has sufficient processing capacity, and can process organic waste in an amount about three times the conventional processing capacity (15 kg / day). became. The organic waste decomposition method according to the present invention can process raw garbage, which has required a processing time of about half a day in the prior art, in about 4 hours. It became possible to increase.

  The organic waste decomposition method of the present invention can decompose food waste such as food waste, bread waste, vegetable waste, and fruits in about 4 hours. Even grease trap sludge accumulated in a fat settling tank can be decomposed in about 8 hours, and residual sludge containing petroleum-based polymer flocculant, which is the most difficult to treat, can be decomposed in about 12 hours. It was.

  Moreover, the organic waste decomposition method of the present invention did not generate any wastewater during the treatment of garbage, which has been a problem in the past. This is because the temperature in the treatment tank 1 is maintained between about 40 ° C. and 50 ° C., so that the moisture in the treatment tank 1 is vaporized and useful microorganisms grow in the treatment tank 1. From this, it is considered that useful microorganisms consume water.

  Moreover, since the temperature in the processing tank 1 is maintained between about 40 degreeC-50 degreeC, the decomposition | disassembly processing method of the organic waste of this invention is a state with the high decomposition | disassembly capability of the organic waste by a useful microorganism. Can be maintained. The organic waste decomposition treatment method of the present invention does not require a heat source such as a heater to maintain the temperature in the treatment tank 1, and can greatly reduce power consumption.

  The deodorization tower 51 b deodorizes the exhaust discharged from the treatment tank 1 through the exhaust pipe 50, and sends the deodorized exhaust to the blowing means 4 through the circulation path 43. The blower means 4 sends the deodorized exhaust gas to the intake pipe 44 through the blower passage 41 by the blower 42. Further, the blowing means 4 is provided with the active oxygen supply means 3 so that the active oxygen supply means 3 takes in the outside air to generate active oxygen, and sends the active oxygen to the intake pipe 44 through the air passage 41. is there.

The drive mechanism 20 includes a motor 24 that can rotate forward and backward, and is configured to be able to drive the stirring member 2 so as to be able to rotate forward and backward.

  The tilling claw is most preferable as the stirring claw 23 because it has strength and durability and can stir and mix the contents well. In addition, the stirring member 2 is not limited to the structure of an Example, It is possible to employ | adopt the various structure which can stir and mix the support | carrier and organic waste, etc. which were accommodated in the processing tank 1.

And an agitating member 2 for agitating and mixing the organic waste, and a blowing means 4 for sending air into the treatment tank 1.

  Further, the organic waste extinguishing apparatus 10 includes, in the treatment tank 1, a carrier supporting microorganisms, one or more useful microorganisms selected from the group of photosynthetic bacteria, Bacillus bacteria, lactic acid bacteria, and yeast, and useful microorganisms. And a microbial activator that activates the organic waste, so that the organic waste is decomposed and eliminated.

  Since the organic waste decomposition method shown in FIG. 9 does not include an active oxygen supply means, it takes about 8 hours to decompose food waste such as food waste, bread waste, vegetable waste, and fruits. Except degradable organic waste, organic waste can be reliably decomposed. This decomposition treatment method treats organic waste in an amount about 1.5 times the treatment capacity of the prior art by accelerating the growth of useful microorganisms with the microbial activator contained in the treatment tank 1. Became possible.

  This decomposition treatment method is the same as the decomposition treatment method of Example 1 except that the active oxygen supply means 3 and the deodorization means 5 are not provided. In this decomposition treatment method, it is not necessary to house the SOD-producing microorganism in the treatment tank 1, but it is possible to use the SOD-producing microorganism as a useful microorganism for decomposing organic waste.

  As described above, the organic waste decomposition treatment methods of Examples 1 and 2 were able to improve the processing capacity by 1.5 to 3 times compared to the prior art, thereby reducing the power consumption of the apparatus. In addition, the apparatus can be miniaturized and can be installed in a narrow place.

  As shown in FIGS. 10 and 11, the active oxygen supply unit 3 includes a magnetic field generation unit that generates a magnetic field in the air passage 41 that sends air into the treatment tank 1, and a magnetic field in the air passage 41 that generates the magnetic field. It is also possible to comprise the electron generating means 132 that emits electrons in a direction non-parallel to the direction. In the illustrated embodiment, the magnetic field generating means comprises an electromagnetic coil 133 that generates a static magnetic field in the same direction as the blowing direction. The electron generating means 132 includes a discharge needle 132b disposed at a predetermined angle with respect to the magnetic field direction, and a facing electrode 132c as a counter electrode.

  As shown in FIG. 11, the electron generating means 132 is provided in the middle of the air passage 41 and adjacent to the upstream side of the electromagnetic coil 133. The electron generating means 132 has a cylindrical air supply tube 132a formed of non-conductive synthetic resin, and a discharge in which the needle tip is arranged in the air supply tube 132a in the air blowing direction (arrow direction in the figure).

Can be emitted.

  As shown in FIGS. 10 and 11, the magnetic field generation means includes an electromagnetic coil 133 and a current supply mechanism 137 that supplies a direct current to the electromagnetic coil 133. The electromagnetic coil 133 is adjacent to the electron generating means 132 downstream in the blowing direction, and is wound around the nonmagnetic tube 131 made of a nonmagnetic material along the circumferential direction.
