Oyster shells are only reduced by a few percent when heated at 610 ° C., and 58% carbon dioxide has a very high dissociation energy and requires a huge amount of heat for gasification. In order to overcome this and make CaO, there is a case where dry distillation heating that works synergistically with far-infrared radiation, nitrogen gas atmosphere, superheated steam atmosphere, etc. efficiently promotes gasification in another wood carbonization example. In addition, it is known that activated carbon is produced by activation by dry distillation and heating at 1000 ° C. while blowing steam into the charcoal, and it is known that the material reforming operation depends on the maintenance of conditions, and biomass regeneration technology is competing. .

The rice husk wrapping mature brown rice contains a hard tissue, silicic acid and a germination enzyme abdic acid, and when it is crushed at low temperature, the enzyme is activated and leads to organic fusion reaction with silicic acid.
Mineral-microl extracted from rocks affected by high heat (produced in Fukushima Prefecture) is a “silicate tetrahedral structure” with silicon as the core, and the tetrahedral structure is distorted by the influence of high heat. Inspired by the romance that the repulsive force was the source of activation and the minerals gave vitality to other substances, the Momiji low temperature crusher was devised, and a new technique for utilizing straw was developed.
When mature rice bran is crushed at low temperature, various amino acid groups (minerals) are created by the fouling fertilization method based on the law-reversing decomposition led by weaving inhibitor abscisic acid and extract component momilactone phenol, which are included with organic silicic acid. Did the biochemical reaction of the Bokashi fertilization method produce a distorted silicate tetrahedral structure? And gave me hope. The attractiveness of rice bran and the firing temperature of modern cement at 1450 ° C or higher is much higher than the temperature of pure CaO quick calcification (limestone crystallizes at 1000 ° C), resulting in distortion of the quicklime structure It may be a teaching that it is correct to understand that it has been heated to a high temperature and has a strong hydration reaction. This is a phenomenon that makes me think about the depth of material structures.

Expectations are high for fly ash and silica fume, which are highly ionized along with oyster shell quicklime, in order to induce hydration under the special conditions of water. The hydration reaction proceeds centering on 3CaO.Al ₂ O ₃ and 3CaO.SiO _2, and densification and curing proceed by the generated C—S—H (calcium-silicate-hydrate).

Sludge deposited on the bottom of dams and sedimentation tanks at downstream locations, such as sediment runoff due to natural rain and rain and sedimentation of wastewater generated as part of industrial activities, continues to increase, reducing dam function and industrial activities. There is no end to the topic of braking. Moreover, since the actual condition is characterized by a high proportion of organic matters, it is necessary to respond while taking these characteristics into consideration.
The inventors, following the patent application in Section 0011, construct an adaptation means that utilizes regenerated biomass as in the prior application for the treatment of sludge remaining in water.

Means for carrying out the task

  The present invention identifies the characteristics of submerged sediment sludge and combines highly ionized substances commensurate with it to form a solidified substrate, and solidifies by a rapid hydration reaction parallel to organic aggregation in a partial enclosure device. The system will be raised after the reaction is completed and secondarily treated on land.

The core of this function is agglomeration of soft organic matter and hydration reaction of other objects, but the front part that induces and initiates it is the addition of plum vinegar and marinex that ionizes rice bran And the activation function of the germination inhibitory enzyme in cooperation with the silicic acid of the low temperature cracked rice.
The rear part is expected to be a synergistic hydration reaction between oyster shell quicklime, which is highly ionized, and fly ash and silica fume.

In the following, materials that depend on the present invention will be verified.
The basic oyster shell quicklime is supposed to be fired first, but since that part has been proposed in the prior application (Japanese Patent Application No. 2005-43087), it will be omitted.
However, because the objects to be used in this application are underwater, and many of them contain heavy metals, etc., solidification by hydration reaction is performed simultaneously with the aggregation of organic matter while reliably collecting it. Since the basic oyster shell quicklime CaO is not only high in purity, high-temperature treatment that causes distortion in the tissue body that enhances ionization is desirable.
As described in Non-Patent Document 5, the information that the repulsive force is added to the activation of the material structure distortion caused by heat (the fish baked with far infrared rays is delicious because its tissue is distorted) is valuable. . The history of modern cement being heated to 1450 ° C, where the raw material is semi-melted, is highly improved in quality, and it is imagined that it is not heating that only pulls CO ₂ away from CaCO _3. With the goal of increasing the ionization activity of the oyster shell, improvement efforts to improve the oyster shell firing temperature level of Japanese Patent Application No. 2005-43087 are required.

Regarding the solidification function of the present invention, there are fly ash and silica fume which are expected as materials supplementing oyster shell quicklime.
Fly ash is ash that accumulates in the dust collector of a thermal power plant. When pulverized coal passes through a high-temperature location, the residue melts and becomes spherical by surface tension and solidifies outside the furnace. SiO ₂ -45% As described above, Al ₂ O ₃ is highly ionized. JIS has a quality regulation as a concrete admixture.

Silica fume is a by-product in the production of ferrosilicon and metal silicon, and the main component is mostly amorphous SiO ₂ -90% or more, with an average particle size of about 0.1 microns and a surface area of about 20 m ² per gram. It is a highly ionized substance with spherical ultrafine particles. For this purpose, the effect of getting into the cement hydrate and densifying the concrete structure (micro-feeler effect), or the reaction of the cement hydrate and silica fume reacting to produce a stable substance (Posora effect) ) Is expected to improve the sludge solidification function under special circumstances of underwater.

  As a material that realizes the organic agglomeration function, the rice bran is mixed with ume vinegar and marinex to give an ionization function, which promotes organic ionization and leads the agglomeration. Since organic substances contain protein enzymes, the above materials cause an organic agglutination reaction, a category that should be called an organic chemical complex enzyme reaction, due to the synergistic action of organosilicic acid in cold-cracked rice straw and the activation of the germination inhibitor abscisic acid. It is expected to induce and induce.

The sludge to be treated according to the present application often contains heavy metals peculiar to the region (for example, the Shijuyoda Dam in Iwate Prefecture contains arsenic from the old mine drainage of the Matsuo Sulfur Mine). There is a tight situation where you have to carry it out while minimizing pollution.
In addition to the role of promoting ionization of materials according to the previous paragraph, we will strive to prevent pollution with the help of Marinex's fulvic acid for environmental pollution caused by stirring and pollution that may also occur in the construction business etc. according to the next paragraph. This is another necessary method. For details on the functions of Marinex, please refer to the Japanese Patent Application “Seagrass Reef and Equipment Recycling Biomass”.

  For the reason described above, the present solidifying agent has devised a device that can be uniquely handled in view of the circumstances that require construction while minimizing the exposure of the bottom of the water bottom. Although the drawings are shown in detail in the examples, conceptually explained, a circular drum-like structure having a significant length and diameter with a flexible container bag is inserted into the bottom mud, and the rotating blades are blown while blowing the solidified base. The mud is agitated and mixed, wrapped in a flexible container bag, allowed to cure, agglomeration and hydration reaction proceed, solidify, wait for the reaction to finish, and are secondarily treated on land. Although it is a very time-consuming work, it will be one measure that can be done while minimizing exposure and destruction of the bottom floor and preventing environmental pollution.

The invention's effect

  The present invention, which can provide a concrete path that links the recycling and recycling of biomass and the environmental business, is a proposal for solving current social issues.

Best Mode for Carrying Out the Invention

  As mentioned in the previous section, the business related to the recycling and recycling of biomass including the present invention and environmental conservation is not a problem only for specific regions and specific people. Widely bring about mutual assistance, compatibility, and mutual benefit by forming a network in which various production areas, industries, and businesses involving many people are involved. The strength of the relationship building is linked to the rise and fall of the responsibility of modern society on biomass regeneration and environmental issues.

At the time, it adheres to the outer wall mud.
The lower net of the flexible container is a mechanism in which a fulcrum ring is provided on the opposite side of the outlet, and when the bottom of the bottom is opened by slightly lifting the container at the end of mixing, the rope is pulled and the bottom is closed.

  With the above device mechanism, if 1- is inserted at a significant depth, it is driven by 4- as the solidified base is injected from the 5-pressure feeding hose, and the 2-propeller rotates. Then the mud is stirred and mixed. When the press mixing is finished, raise the container slightly from the bottom of the water, pull the lower rope of the flexible container to close the bottom, pull the container while slowly rotating the propeller backward, and reach the upper end of the flexible container. Wear. Since it takes time to agglomerate and solidify, when the reaction is completed after a predetermined curing time, it is pulled up and treated on land for two hours. Marinex is mixed in the compressed air of the drive unit to try to clean the surrounding environment.

  The pulled solidifying agent is spread and dried quickly, for example, by repeatedly injecting and stirring low-temperature crushed rice crackers and marinex extract diluent. -This is based on a reference from the event that a mixture of an equal amount of crushed rice crackers and an enzyme agent left in a sewage treatment sludge led to chemical reaction drying.

As mentioned in the section of the effect of the invention, both the biomass recycling and the solution to environmental burdens of the present application are problems on an industrial scale.
For example, the Biomass and Nippon Comprehensive Strategy formulated in December 2002 can be said to be a nationally obligatory act that has received international responsibility, but there is little information on the progress of actual results.
Biomass regeneration technology including energy conservation related (new energy industry) has extremely high proposals, but there are extremely few proposals for technology that anyone can participate anywhere in the country. The significance of the fact that the present invention has clarified the technology that can broaden the regenerative circulation in the grass roots is convinced that it will provide a turning point for the future industrial policy for baiomas.
As mentioned in paragraph 0005, the marine ecosystem, for example, must know the efforts to incubate its function to learn about the environmental purification function that operates biosynthesis to capture CO2 that oyster shells say 58%. I remembered it.
The improvement of the upper limit of the oyster shell firing temperature of 0015 is significant on an industrial scale because it extends the range of biomass regeneration.
