Description

The present invention relates to a treatment agent. More specifically, the present invention relates to a treatment agent used for treatment of manure and the like.

In general, toilets can be roughly classified into a flush type that allows manure to flow into the sewer together with water, and a flush type that can be stored in a tank. In the case of a flush toilet, manure is flushed with the water into the sewer and processed at the sewage treatment plant. On the other hand, in the case of a draw-up type toilet, manure is drawn from the tank by a vacuum car or the like and is transported to a sewage treatment plant for processing.

In a sewage treatment plant, sewage containing manure is stored in a septic tank, where organic matter in manure is decomposed and removed by the action of microorganisms such as activated sludge, and then the water is purified through several stages of treatment, Released into the river.

However, in the event of a long-term blackout or water outage due to a disaster such as an earthquake, the toilet cannot be used, and a large amount of manure accumulates in each household. Malodors continue to emanate from the large amount of manure, and if left untreated, the odor will significantly deteriorate the living environment. Therefore, in general, a method of storing manure in a plastic bag and storing it in a sealed state is generally used. However, since the plastic bag is easily damaged, the manure is leaked due to damage during storage. There is a problem that the odor is emitted from the surroundings. In addition, the manure placed in the plastic bag rots with time and accumulates odor gas, and there is a problem that odor gas leaks from the plastic bag due to the pressure.

In addition, simple toilets are used at construction sites, event venues, campsites, etc., but in conventional simple toilets, a large amount of feces and urine accumulates during installation, and odors are emitted around. There's a problem.

Under such circumstances, Patent Document 1 discloses that an acrylic acid monomer aqueous solution having a neutralization rate of 50 mol% or more is subjected to a polymerization reaction, and after adding a hydrophilic polyvalent epoxy compound and a polymerization initiator, light is emitted. Irradiate to cause a repolymerization reaction to give a gel solid, and further dry this gel solid with hot air,
A superabsorbent polymer for human waste treatment, which has been ground, screened, and surface-treated by adding a surface cross-linking agent, is disclosed. However, even when manure is treated using the superabsorbent polymer described in Patent Document 1, the material to be treated decays within a few days after the treatment, and there is a problem that malodor and gas are generated. .

Therefore, Patent Document 2 discloses a fecal treatment agent containing slaked lime or limestone as a measure for suppressing malodor of the object to be processed and generation of gas. It has been found that when manure is treated using the treatment agent, the treatment agent suppresses the generation of malodor and gas, and it is difficult for odors to occur even after several days after treatment.

JP 2008-095016 A International Publication No. 2010/070945

However, since slaked lime or limestone is fine particles, the treatment agent described in Patent Document 2 has a dust problem that slaked lime or limestone is scattered around.

In addition, the present inventor has recognized that there are problems such as usage that have not been recognized in the past.

Therefore, in this invention, it aims at solving the dust problem of slaked lime or limestone.

  The above object is solved by providing the following invention.

(1) A granular treatment agent comprising a binder granule containing slaked lime or limestone and a binder, and a water-absorbing polymer.

(2) The granular processing agent according to (1), wherein the content of the binder is less than 5% by mass of the total mass.

(3) The manufacturing method of the granular processing agent as described in (1) or (2) which further contains an acidic solid substance.

(4) Any one of (1) to (3), wherein an average diameter of the binder granule is less than 3 mm.
The granular processing agent as described in 1.

(5) At least one selected from the group consisting of zeolite, activated carbon, baking soda and lubricant.
The granular processing agent according to any one of (1) to (4), further comprising a seed additive.

(6) A step of mixing and pulverizing slaked lime or limestone and a binder to obtain a binder granule, a step of mixing the binder granule and a water-absorbing polymer to obtain a granular treatment agent, The manufacturing method of the granular processing agent as described in any one of (1)-(5) containing this.

(7) A granular treatment agent according to any one of (1) to (5) or a granular treatment agent obtained by the method according to (6), which is used for excrement treatment.

  The present invention has the following effects by the above-described invention.

(1) A first aspect of the present invention is a binder granule containing slaked lime or limestone and a binder,
And a water-absorbing polymer, and a granular processing agent (hereinafter, also simply referred to as “processing agent”). Even if it stirs at the time of use by this structure, since slaked lime or limestone is solidified, it does not scatter and is safe. Furthermore, the granular processing agent of the present invention comprises:
The granular treatment agent may be arranged in advance in a container for excrement, but it may be added later to a container containing excrement. As described above, since the granular processing agent of the present invention does not scatter, even if it is added afterwards, it is easy to handle. In particular, in use at the time of disaster, fine dust of slaked lime or limestone, which may be affected by the human body, is not generated, and it is extremely excellent in terms of handleability and significantly suppresses health damage. Specifically, the treatment agent that easily scatters easily adheres to the skin or the like. In such a case, while the immunity is reduced due to prolonged life in an evacuation center or the like, there is a high possibility of causing dermatitis or the like due to some component of the treatment agent adhering to the skin or the like. However, since the treatment agent of the present invention has solidified slaked lime or limestone, which is feared to affect the human body, it can significantly suppress the slaked lime or limestone dust from dancing. It becomes easy to suppress. Moreover, even if it considers the use in the sealed vehicle (for example, at the time of traffic congestion), it can be said that the solidified processing agent which suppresses scattering of slaked lime or limestone dust is very suitable.
Furthermore, the granular processing agent of the present invention can easily and efficiently treat a large amount of feces and urine. Moreover, even after processing, the processing object hardly rots, and the generation of malodor and gas can be suppressed. That is, it can also be used for disinfectants, deodorants, bactericides, or sterilizers, leading to prevention of infectious diseases.

(2) Moreover, in the 1st granular processing agent of this invention, content of the binder in a granular processing agent is less than 5 weight%. According to the granular processing agent of the present invention, since the binder binds and solidifies slaked lime or limestone that is easily scattered, an amount of binder that can bind slaked lime or limestone is required. For example, compared with the case where inclusions other than slaked lime or limestone are included, the slaked lime or limestone and the binder are sufficiently bound with a small amount of binder. Therefore, since the amount of the binder can be reduced as compared with the conventional fixed treatment agent, the content of the highly water-absorbing polymer and slaked lime or limestone can be relatively increased, and the water absorption amount as the treatment agent And the effect of suppressing the generation of bad odors is improved.

(3) Moreover, the 1st granular processing agent of this invention can neutralize the ammonia which may generate | occur | produce from a to-be-processed object (for example, stool, urine) by further containing an acidic solid substance. Therefore, malodor can be further suppressed.

(4) Moreover, in the 1st granular processing agent of this invention, the average diameter of a binder granule is 3 mm.
By being less than, while improving the handleability, the contact area with the workpiece increases,
The reaction efficiency with the object to be processed can be improved.

(5) Moreover, said effect improves further by the 1st granular processing agent of this invention further containing at least 1 sort (s) of additive selected from the group which consists of a zeolite, activated carbon, baking soda, and a lubrication agent. To do.

(6) The second aspect of the present invention is a step of mixing and pulverizing slaked lime or limestone and a binder to obtain a binder granule, and mixing the binder granule with a water-absorbing polymer to form a granule And a step of obtaining a treatment agent. By this production method, it is possible to produce the treatment agent simply and efficiently without scattering fine particles such as slaked lime or limestone. That is, according to the production method of the present invention, fine dust is not generated, it is very excellent from the viewpoint of handleability, and health damage can be significantly suppressed. For example, when the raw material is fine particles, the fine particles are likely to scatter and easily adhere to the skin or the like, which may cause dermatitis or the like. However, according to the production method of the present invention, after obtaining a binder by mixing slaked lime or limestone and a binder, the binder is pulverized to obtain a binder granule. It is possible to significantly suppress slaked lime or limestone dust from flying. Therefore, it becomes easy to suppress such health damage. In addition, the obtained granular treatment agent is
Since slaked lime or limestone is solidified, it is difficult for slaked lime or limestone dust to scatter.

(7) The granular treatment agent obtained by the first granular treatment agent of the present invention and the second production method of the present invention includes a binder granule containing slaked lime or limestone, and a binder, and water absorption And is particularly suitable for manure treatment. That is, a large amount of feces and urine can be processed using the granular processing agent of the present invention, and the rot of the object to be processed hardly occurs after the processing, and the generation of malodor and gas can be suppressed.

  Hereinafter, embodiments for carrying out the present invention will be described in detail.

(1) First of the present invention
<Granular treatment agent>
1st of this invention is a granular processing agent containing the binder granule containing slaked lime or limestone, and a binder, and a water absorbing polymer. As described above, the treatment agent of the present invention is excellent in handleability because slaked lime or limestone is bound by a binder and solidified. In addition, as each form of the component which comprises the 1st granular processing agent of this invention, although slaked lime or limestone exists in the state mutually bound by the binder, a water absorbing polymer is slaked lime or limestone, It exists in a state of being simply mixed with the binder and substantially not bound to either. In the present specification, “binding” means slaked lime or limestone,
This means that the binder and the binder are integrated and cannot be separated into the respective components. On the other hand, “mixing” simply means a state in which two components (for example, a binder granule and an absorbent polymer) coexist in a state where they can be separated from each other.

As the shape of the granular treatment agent of the present invention, including a binder granule containing slaked lime or limestone and a binder, and a water-absorbing polymer, if the slaked lime or limestone and the binder are solidified, There is no particular limitation. For example, any shape such as a spherical shape, a cylindrical shape, a middle-high cylindrical shape, and a rectangular parallelepiped shape may be used.

The binder granule contained in the granular treatment agent and the average particle diameter of the water-absorbing polymer will be described later.
In either case, the average diameter is preferably less than 3 mm. By being in such a range, the above-mentioned problems due to dust can be significantly solved, and the contact area with the object to be processed is increased while improving the handleability, and the reaction efficiency with the object to be processed. It is easy to improve the above-described effects. Moreover, it is preferable that the other added thing which can be contained in the granular processing agent of this invention is also less than 3 mm.

In the granular processing agent of the present invention, the amount of the binder is preferably less than 5% by mass of the total mass of the processing agent. The granular processing agent of the present invention contains slaked lime or limestone, a binder, and a water-absorbing polymer, but since the binder binds only slaked lime or limestone, the water-absorbing polymer or the like is bound to the binder. In comparison, the amount of binder can be significantly reduced. Therefore, the amount of binder is reduced, slaked lime or limestone, water-absorbing polymer,
Other components such as an acidic solid substance can be increased, and a desired effect can be given by the added components.

Moreover, as content of the slaked lime or limestone in the granular processing agent of this invention, Preferably it is 1-98 mass% with respect to the total mass of a granular processing agent, More preferably, it is 5-95 mass%.
More preferably, it is 10-90 mass%, It is preferable to add so that it may become about 15-80 mass% especially preferably. In such a range, the effect of stopping the fermentation and decomposition activities of microorganisms is particularly remarkable. Further, the content of the binder in the granular treatment agent of the present invention is preferably less than 5 mass%, more preferably 0.01 to 4.9 mass%, based on the total mass of the granular treatment agent. Furthermore, it is preferable to add so that it may become about 0.1-4.5 mass%. In such a range, the powdered slaked lime and the water-absorbing polymer are granulated, and the effect of preventing dust scattering during use is particularly remarkable.

In the granular treatment agent of the present invention, the water-absorbing polymer is 1 to 98 of the total mass of the treatment agent.
It is preferably mass%, more preferably 5 to 95 mass%, and 10 to 90 mass%.
Is more preferable, and it is especially preferable that it is 15-80 mass%. In such a range, it is possible to efficiently absorb the water of manure, and when used in a simple toilet,
It can be solidified into a jelly shape, and the effects of preventing leakage from the plastic bag and preventing the diffusion of filth are particularly remarkable.

Further, the granular treatment agent of the present invention contains slaked lime or limestone and a binder, but the amount of the binder granule in the granular treatment agent is not particularly limited, but for example, the amount of the binder granule is treated. It is preferably 1 to 90% by mass of the total mass of the agent, more preferably 3 to 80% by mass, still more preferably 5 to 70% by mass, and particularly preferably 7 to 60% by mass. Preferably, it is 10 to 50% by mass.

When the average diameter of the binder granule is less than 3 mm and the average thickness is less than 3 mm, it is preferable because the reaction is sufficiently fast when it comes into contact with the object to be processed, and also from the viewpoint of producing such a treatment agent. It is easy and particularly preferred. In addition, if a binder granule is a column shape, a middle-high column shape, and a rectangular parallelepiped shape, a long axis will become an average diameter. On the other hand, the minor axis is the average thickness.

In addition, animals and livestock infected with foot-and-mouth disease and bird flu, or their carcasses, and food (plants, etc.) eaten by the animals and livestock
It is effective for sterilizing, sterilizing, disinfecting, deodorizing the livestock house where the animal or livestock existed or the existing livestock house, or the soil or road near the livestock house. This stops fermentation and decomposition of organic matter. Then, it is sterilized, sterilized and disinfected. And the effect which reduces an odor can be acquired. Moreover, since slaked lime mainly adsorb | sucks a sulfide, it can be said that the odor reduction effect by using slaked lime is large also from this point.

The shape of the slaked lime is not particularly limited, and examples thereof include powdery and pellet shapes,
From the viewpoint of effectively dispersing slaked lime with respect to stool, it is preferably in a granular form.

Within such a range, the production is facilitated and the production cost is reduced, the contact area between the resulting treatment agent and the object to be treated is increased, the reaction efficiency is improved, no granular material is produced during the treatment, and the unreacted material. No longer remains. If necessary, the slaked lime may be used in combination of two or more slaked limes having different average particle sizes.

The slaked lime used in the present invention may be surface-treated with a hydrophobic coating agent. Moreover, the slaked lime used by this invention may synthesize | combine and may use a commercial item.

(Limestone)
Limestone (calcium carbonate), which can be included in the granular treatment agent of the present invention, has a composition formula CaCO _3.
It is a carbonate of calcium represented by Since limestone is alkaline, it has the same effect as slaked lime.

The shape of the limestone is not particularly limited, and for example, a granular shape, a pellet shape, etc. can be exemplified.

And no unreacted material remains. As needed, the said limestone may be used in combination of 2 or more types of limestone from which average particle diameter differs.

As a method for preparing limestone, a method of purchasing a commercially available product is preferable, and for example, a tancal from Ube Materials, an industrial tancal from Yoshizawa Lime Industry Co., Ltd., and the like are preferable.

(Binder)
In the granular treatment agent of the present invention, the binder contained in the binder granule may be an organic binder described below or an inorganic binder such as baking soda. However, in view of the binding property, preferably, the binder contained in the binder granule is a cellulosic binder,
Preferably, the binder is at least one organic binder selected from the group consisting of a polymer binder and a starch binder. In particular, the binder is preferably a cellulose binder.

The binder granule according to the present invention is characterized in that slaked lime or limestone is solidified by a binder. The binder granule has sufficient strength due to the form in which the binder (binder) is contained. Therefore, the binder granule and the granular processing agent using the binder granule are transportable and handleable. Is excellent.

200G, W-250, W-300G, W-400G) and the like are preferably used. Among them, Cerrosa K2 manufactured by Asahi Kasei Chemicals, KC manufactured by Nippon Paper Industries
The floc is preferable from the viewpoint of bonding strength and disintegration because the shape is fibrous. In addition, the present inventor has found that KC Flock manufactured by Nippon Paper Chemicals Co., Ltd. and Cerossa K2 manufactured by Asahi Kasei Chemicals Co., Ltd. are very excellent in terms of binding properties. In particular, Cerrosa K2 manufactured by Asahi Kasei Chemicals Co., Ltd. has a granular shape and fine particles, and thus has a high binding force and is extremely excellent in terms of smooth feed from the hopper of the tableting machine.

[Water-absorbing polymer (also referred to as water-absorbing agent or polymer water-absorbing agent)]
The water-absorbing polymer (water-absorbing agent) contained in the granular processing agent of the present invention serves to assist slaked lime or limestone. That is, for example, when only slaked lime or limestone is used as the treatment agent, it may not be able to absorb the moisture of the object to be treated (for example, in manure) and may become a muddy state. When slaked lime gets wet, the slaked lime itself may give off a unique malodor. Further, if the manure remains in a muddy state, the manure may come into contact with the air, and the fermentation and decomposition of the manure may proceed.

Since the granular treatment agent of the present invention contains a water-absorbing polymer (polymer water-absorbing agent), it can absorb and solidify moisture in the object to be treated. When slaked lime or limestone and water-absorbing polymer are added to the object to be treated, the object to be treated solidifies, and the solidified object is covered with slaked lime or limestone to stop the fermentation and decomposition activities of microorganisms. As a result, the above-described effects can be obtained. Moreover, the addition amount of slaked lime or limestone can be reduced, and the malodor which slaked lime or limestone itself emits can be reduced more. Moreover,
Since the water-absorbing polymer swells when it comes into contact with moisture, it serves as a base point for the collapse of the solidified treatment agent.

The water-absorbing polymer used in the present invention is not particularly limited as long as it does not adversely affect the effects of the present invention, and known substances can be used. Specific examples thereof include, for example, starch-acrylonitrile graft polymer hydrolysates, starch-based water-absorbing polymers such as starch-acrylic acid graft polymers, cellulose-acrylonitrile graft polymers, cellulose-styrene sulfonic acid graft copolymers. Cellulose-based water-absorbing polymers such as polymers, polysaccharide-based water-absorbing polymers, protein-based water-absorbing polymers such as collagen, polyvinyl alcohol-based water-absorbing polymers such as polyvinyl alcohol-crosslinked polymers, crosslinked sodium polyacrylate, heavy acrylic acid Crosslinked polymer partial sodium salt, acrylic water-absorbing polymer such as sodium acrylate-vinyl alcohol copolymer, maleic anhydride water-absorbing polymer, vinyl pyrrolidone water-absorbing polymer, polyethylene glycol di Polyether type water-absorbing polymer such as acrylate crosslinked polymer and the like, and the like.
These water-absorbing polymers may be used alone or in combination of two or more. These water-absorbing polymers may be synthesized or commercially available. Examples of commercially available products include, for example, Aquakeep (registered trademark) SA (manufactured by Sumitomo Seika Co., Ltd.), Aquaric (registered trademark) CA (manufactured by Nippon Shokubai Co., Ltd.), Sunfresh, Aquapearl (Sundia Polymer Co., Ltd.) Product), Hymosub HS-960 (manufactured by Hymo Co., Ltd.) and the like. Among these water-absorbing polymers, Hymosub HS-960 (manufactured by Hymo Co., Ltd.) is more preferable.

The average particle diameter of the water-absorbing polymer contained in the granular treatment agent of the present invention is not particularly limited, but is preferably 50 to 1000 μm, more preferably 80 to 850 μm, and further preferably 100 to 600 μm. . In addition, since these water absorbing polymers do not have a great influence on a human body, they may be fine particles.

Among Aqua Keep (registered trademark) SA (manufactured by Sumitomo Seika Co., Ltd.), preferably SA-
50II or SA60-S, and SA60-S is preferable from the viewpoint of water absorption. Further, SA-50II is preferable from the viewpoint of cost. The shape of the water-absorbing polymer is not particularly limited, and examples thereof include granule, powder, granule, and pellet.

The content of the water-absorbing polymer can be adjusted as appropriate depending on the type and shape of the water-absorbing polymer and the amount of water contained in the object to be treated, but is 1 to 90% by mass with respect to the total mass of the granular treatment agent. It is preferably about 5 to 50% by mass or about 10 to 48% by mass.
If it is this range, the effect of a water-absorbing polymer can be acquired significantly, an unreacted water-absorbing polymer does not remain, and it is advantageous in cost.

[Acid solid material]
A particularly preferred form of the granular treatment agent of the present invention contains an acidic solid substance. When the granular processing agent of the present invention contains an acidic solid substance, it is possible to neutralize ammonia that can be generated from an object to be processed (for example, stool, urine). Therefore, malodor can be further suppressed. When an acidic solid substance is added to the granular processing agent of the present invention, the slaked lime or limestone and the binder may be present in a state of being bound to each other as a binder granule, or may be present alone. Also good.

In particular, the inclusion of an acidic solid component such as sodium dihydrogen phosphate has the following effects. That is, when the ratio of slaked lime increases in the treatment agent, the alkali concentration increases, and there may be an environment where ammonia is likely to be generated. In such a case, a bad odor derived from ammonia may occur. Therefore, to neutralize ammonia and maintain the sterilizing ability of slaked lime,
It is particularly preferred to include an acidic solid component such as sodium dihydrogen phosphate. Further, the second component such as sodium dihydrogen phosphate is also preferable from the viewpoint that the water absorption capacity of the water absorbing polymer is not deteriorated so much.

In addition, when the acidic solid substance is composed of only the first component, for example, when a polyacrylate is used as the water-absorbing polymer, the “salt portion” of the polyacrylate is consumed, which is preferable from the viewpoint of water absorption characteristics. There may not be. However, it is preferable in that the effect of neutralizing ammonia in the object to be treated (for example, urine) is high. On the other hand, when an acidic solid substance consists only of a 2nd component, it is preferable from a viewpoint of a water absorption characteristic. Of course, the effect of neutralizing ammonia in the object to be treated (for example, urine) is also significantly high.

(2) Second of the present invention
<Method for producing granular treatment agent>
The second aspect of the present invention is a step of mixing and pulverizing slaked lime or limestone and a binder to obtain a binder granule, and mixing the binder granule with a water-absorbing polymer to obtain a granular treatment agent. A process for producing a granular treatment agent. The present inventor has found that by using such a production method, a granular treatment agent capable of treating a large amount of manure without dust scattering can be obtained.

  Hereinafter, the method of the present invention will be described step by step.

[Preparation of bound granule]
In the method for producing a granular treatment agent of the present invention, first, slaked lime or limestone and a binder are mixed and pulverized to obtain a binder granule. Since the binder granule obtained by the said process is solidified by including a binder, it is excellent in handleability. In addition, the slaked lime or limestone constituting the binder granule is present in a state where the slaked lime or limestone and the binder are bound to each other by the binder.

Hereinafter, a method for producing a binder granule will be described by dividing it into several preferred embodiments. Of course, it is not limited to the following method.

The binder granule can be produced by mixing slaked lime or limestone and a binder and pulverizing the solidified product obtained by compression so as to obtain a desired size or weight.

[mixture]
The method of mixing slaked lime or limestone with a binder is not particularly limited.
A binder may be added to slaked lime or limestone, or slaked lime or limestone may be added to the binder and mixed with a stirrer or the like. If necessary, in addition to slaked lime or limestone and a binder, an additive such as an acidic solid substance or a lubricant may be mixed in a predetermined amount. The temperature and stirring conditions for mixing are not particularly limited, but stirring is preferably performed so as to be uniform at 15 to 40 ° C. Moreover, you may mix, feeding to the tableting machine performed by the solidification described below.

[Solidification]
Next, the slaked lime obtained above or a mixture of limestone and binder (hereinafter also referred to as “mixture”) is compressed to solidify, and the solidified product obtained by compression is pulverized.

(Solidified with a desktop manual tableting machine)
The compression can be performed using, for example, a table-top manual tableting machine (one each for punch and die). First, each component (mixture) to be solidified is put into the bowl by hand or spoon.
At this time, there is no need to consider the difficulty of feeding. Thereafter, the lever is manually lowered (hydraulic) and pressure is applied to solidify each component (mixture), thereby producing a solidified product containing slaked lime or limestone and a binder. The advantage of the tabletop manual tableting machine is that it takes a considerable amount of time,
Even if it is a combination that is hard to solidify because it is retained and pressure is applied, it can be solidified. For example, when a ridge having a small diameter (diameter 7 mm: upper and lower circular plate type) is used, the smaller the diameter, the higher the pressure applied per area, so that even those that are difficult to solidify tend to solidify. On the other hand, for example, when using a bowl having a large caliber (diameter 15 mm: upper and lower planographic type), the larger caliber is disadvantageous for those that are hard to solidify because of a smaller pressure per area, Feeding to the paddle is advantageous and productivity is improved.

(Solidify with continuous tableting machine)
The compression can also be performed using a continuous tablet press.

The continuous tableting machine may or may not be a direct tableting machine. Since slaked lime that can be used as the main component of the present invention has a small particle size, a lubricant may be added to facilitate feeding such fine powder. On the other hand, when the pretreatment is performed, for example, by squeezing lime or slaked lime by tableting a mixture of a binder (binder) mixed with a granulated fine powder by applying a large pressure using a roller compactor You may produce the solidified material containing a limestone and a binder. Considering mass production, for example, a tableting machine (model A
P18-SS etc.) is preferably used. The diameter of the mortar at this time is about 13 mm, and the number of uprights is about 18. If such a tableting machine is used, the raw materials are prepared in a desired ratio, mixed, the mixed raw materials are put into the hopper of the tableting machine, and the tableting machine is used for tableting in a rotary manner. Production is possible and preferable.

Moreover, you may produce the solidified material containing a slaked lime or limestone, and a binder with a continuous rotary tableting machine. Specifically, each component (for example, slaked lime, binder, lubricant) is mixed to prepare a mixture, and the mixture is put into a hopper of a continuous tableting machine for tableting. The shape of the ridge may be, for example, an upper and lower circular plate type.

Thus, there is no restriction | limiting in particular in the method for solidification for producing a binder granule.
As described above, tableting, roller compactor, and wet compression (wet the original material to be compressed with water and compression) may be applied in an appropriate combination.

[Crushing]
Next, the solidified product obtained above is pulverized to obtain a binder granule. According to the production method of the present invention, since slaked lime or limestone is bound by a binder (binder), once it is solidified, fine dust is formed even if it is pulverized into granules. Don't scatter. The production method of the present invention is obtained by pulverizing a solidified product once solidified.
In the powder state in the conventional treatment agent, slaked lime or limestone and binder are replaced with such “
Nothing is known that is made through the process of “solidifying once”. Moreover, the binder granule which consists of slaked lime or limestone and a binder is different from the processing agent of the conventional powder state also from a structural surface.

Moreover, since it is not necessary for the binder (binder) to bind to, for example, a water-absorbing polymer, the amount of the binder (binder) can be reduced, which is economical.

The method for pulverizing the binder granule is not particularly limited, and can be performed, for example, by using a conventionally known atomization apparatus. As a fine granulating device that can be used, a shearing crusher,
It is classified into an impact crusher and a high-speed rotary crusher, and those having one or more of crushing mechanisms such as cutting, shearing, impact, and friction can be preferably used. For example, a sizing machine at Hata Iron Works or a table mill at Okada Seiko can be used. Of course, other devices may be used. Alternatively, it may be crushed with a hammer or the like.

As for the pulverized binder granule, it is preferable to select a granule having a desired particle diameter using a sieve or the like. For example, since the binder granule of the present invention is preferably less than 3 mm, after the solidified product is pulverized, the pulverized product is sieved with a sieve having an opening of about 25 to 2,500 μm and has a small particle size. To obtain a binder granule.

[Preparation of granular processing agent]
A water-absorbing polymer, and if necessary, an acidic solid substance and other additives are added to the binder granules obtained above and mixed to obtain a granular treatment agent. At this time, the order of mixing the above components is as follows:
It does not restrict | limit in particular, Each component may be mixed at once, and each component may be mixed sequentially.

[Use of the granular treatment agent of the present invention]
The use of the granular processing agent of the present invention is not particularly limited. For example, it can be used to treat manure, organic sludge, animals and plants, livestock, livestock barns or soil. The granular treatment agent of the present invention exhibits various effects by being used as a manure treatment agent, an organic sludge treatment agent, an animal and plant treatment agent, a livestock treatment agent, a livestock bar treatment agent, or a soil treatment agent. Specifically, since the granular treatment agent of the present invention is contained in the excrement treatment agent, the treatment agent of the present invention has solidified slaked lime or limestone, so when using the treatment agent, the human body Because dust that may adversely affect the air does not fly, handling is improved. Specifically, manure treatment includes disaster toilets, toilets for traffic jams (toilets used in cars during traffic jams), temporary toilets at construction sites, pet toilets (cat sands and dog toilets), and water washing overseas There are applications in areas without infrastructure. In addition, when the granular processing agent of this invention is used for excrement processing, this excrement includes not only human excrement, but also animal excrement such as cattle excrement, pig excrement, chicken excrement etc., for example. Further, the stool may be stool alone, urine alone, or a mixture of stool and urine. In the case of stool alone, it is preferable to contain a lot of water. In addition, organic sludge treatment is the treatment of contaminated rivers,
It can be suitably used for applications such as food residues discharged from restaurants, treatment of vomit from patients with infectious diseases, treatment of blood, and the like.

The treatment of animals, plants, livestock, livestock houses or soils is specifically applicable to the treatment of animals infected with infectious diseases such as foot-and-mouth disease and bird flu, livestock, their feed, livestock, livestock houses or soil. is there. Powdered slaked lime is usually used for disinfection of foot-and-mouth disease and bird flu. However, since the slaked lime or limestone is solidified in the treatment agent of the present invention, animal and plant treatment agents, livestock treatment agents, and livestock treatments are used. Incorporated in chemicals or soil treatment agents, dust damage is significantly reduced, handling (handling) is improved, and reactivity is not deteriorated. Disinfectant, disinfectant, sterilant, disinfectant It can also be used as an odorant. Usually, slaked lime, limestone, and the like used for disinfection also have granularity, but are generally used in powder form because of poor reactivity. According to the present invention, slaked lime or limestone has good reactivity even when solidified. Furthermore, a water-absorbing polymer (polymer water-absorbing agent) is mixed in the treatment agent, but since this water-absorbing polymer is not solidified, it can swell immediately upon contact with moisture, The polymer performance can be exhibited well. Therefore, the granular processing agent of the present invention is very suitable for disinfecting foot-and-mouth disease and avian influenza, because the reactivity does not decrease and handling is very good. In addition, collection is facilitated.

The granular treatment agent of the present invention can be added later to a container containing manure and used for the treatment of manure. Moreover, the granular processing agent of this invention can be previously arrange | positioned in a toilet bowl. Since the treatment agent of the present invention is granular, it is particularly preferable to be used for the former application. Since this toilet bowl contains the granular treatment agent of the present invention, it has the effect of the granular treatment agent of the present invention.

When the granular treatment agent of the present invention is used for manure treatment, the amount of the granular treatment agent used is preferably in the range of 10 to 200 parts by mass with respect to 100 parts by mass of the object to be treated (for example, manure). The range is more preferably 20 to 100 parts by mass, and further preferably 30 to 60 parts by mass. When the amount of the treatment agent used is less than 10 parts by mass, the contact area between the excreta and slaked lime is reduced, so that the excrement may come into contact with the air and the fermentation and decomposition of the excrement may proceed. On the other hand, when it exceeds 100 mass parts, the residue after a process increases and the waste after a process may increase. In addition, the cost may increase.

Moreover, when arrange | positioning the granular processing agent of this invention previously in a toilet bowl, it is preferable to arrange | position by the quantity of said range. From the viewpoint of ease of handling, the toilet bowl is provided with the granular treatment agent of the present invention, for example, in a portion receiving manure, on a sheet having a water repellent surface or a bag having an inner surface water repellent. It is preferable to keep it, and it becomes very easy to dispose of it by adding manure to it. In addition, feces and urine odors are roughly classified into fecal odors and ammonia odors. Fecal odor is an organic odor, and ammonia odor is an inorganic odor. The ammonia odor is an inorganic odor, and is an odor that hardly diffuses after excretion if a sheet whose surface is water-repellent is bound. However, the stool odor tends to leak and diffuse even when the plastic bag is tied up because the gas is generated from the specimen itself, so that the internal pressure in the sheet (for example, a plastic bag) whose surface is water-repellent is increased. Conventionally known manure treatment agents have a low deodorizing effect, and it has been difficult to suppress manure odor (particularly fecal odor). According to the present invention, a granular treatment agent of the present invention and a toilet containing the granular treatment agent of the present invention are provided, and it is possible to easily and efficiently treat urine and the like without requiring an operation such as stirring. Since it is possible and can be sterilized, it is possible to suppress the generation of bad odors and gases. For example, the toilet situation in the affected area can be remarkably improved, which is very suitable in terms of hygiene.

As described above, the granular processing agent of the present invention is laid in advance in a portable toilet or the like,
From there, you can urinate or defecate. Then, since slaked lime or limestone is solidified, the slaked lime or limestone dust does not rise with the momentum of urination or defecation. Since slaked lime or limestone is a strong alkali having corrosive properties, slaked lime or limestone does not fly up, and therefore, it is preferable from the viewpoint of health without scattering to delicate parts of the human body.

Moreover, according to the preferable form of the toilet bowl used for the granular processing agent of this invention, the granular processing agent of this invention is previously arrange | positioned in absence of water. That is, since it is a dry type which does not require water, the storage stability as a toilet is also improved. In addition, dust and other problems do not occur, and it is possible to urinate and defecate from a portable toilet that has been laid in advance.

In addition, since the treatment agent is arranged in advance in the toilet, after excretion, the user does not need to check his / her own (or care recipient, etc.) feces and urine, and the user can use it comfortably. . On the other hand, after the treatment agent is excreted, it is necessary to sprinkle the treatment agent on manure (or a caregiver or the like), and the user (or caregiver or the like) may become uncomfortable. there were. However, according to the toilet bowl, since the treatment agent is arranged in advance, there is an effect that it is sufficient to discard the toilet bowl as it is without requiring confirmation after excretion.

Moreover, this invention also provides the absorbent article formed by including the granular processing agent of this invention. The absorbent article preferably includes the above-described granular processing agent of the present invention, a top sheet having liquid permeability, and a back sheet having liquid impermeability.

Although the manufacturing method of the absorbent article concerning this invention is not specifically limited, For example, the granular processing agent of this invention is used for the base material (surface sheet) which has liquid permeability, and the base material (back surface) which has liquid impermeability. Sheet) and, if necessary, an elastic member, a diffusion layer, an adhesive tape, and the like are provided to form an absorbent article such as an adult paper diaper or a sanitary napkin.

The granular treatment agent of the present invention can impart a deodorizing function to an absorbent article and exhibits excellent deodorizing performance and absorption characteristics over a long period of time.

Specific examples of such absorbent articles include adult paper diapers that have grown significantly in recent years, hygiene materials such as diapers for children, sanitary napkins, so-called incontinence pads, and the like, and are particularly limited thereto. It is not a thing. The granular treatment agent of the present invention present in the absorbent article has a very excellent deodorizing property and a significant dry feeling, greatly reducing the burden on the wearer and the caregiver. Can do.

The amount of the granular treatment agent of the present invention contained in the absorbent article may be appropriately adjusted according to the use, but in the case of sanitary materials, 5 to 50 g or 10 to 30 g is included therein. Preferably.
