Description

  The present invention relates to an excrement treating agent and an excrement treating method using the same, and more particularly to an excrement treating agent containing slaked lime and an excrement treating method using the same.

  In general, toilets can be broadly 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 poured into the sewer along with water and processed at the sewage treatment plant. On the other hand, in the case of a draw-up type toilet, manure is drawn from a 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 power outage 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 a bad odor is emitted around. There's a problem.

  Under such circumstances, JP-A-2008-095016 discloses a polymerization reaction of an aqueous acrylic acid monomer solution having a neutralization rate of 50 mol% or more, and a hydrophilic polyvalent epoxy compound and a polymerization initiator are added. It is then irradiated with light to cause a repolymerization reaction to form a gel-like solid, and this gel-like solid is further dried, crushed and screened with hot air, and surface-treated by adding a surface cross-linking agent. A highly water-absorbing resin is disclosed.

  However, when excrement is processed using the superabsorbent resin described in Japanese Patent Application Laid-Open No. 2008-095016, there is a problem that the processed material rots within a few days after the processing, and malodor and gas are generated.

  Therefore, the present invention is a manure treatment agent capable of treating a large amount of manure easily and efficiently, hardly causing decay of the treated material after the treatment, and capable of suppressing the generation of malodor and gas, and It aims at providing the excrement processing method using this.

  The above object is achieved by the following (1) to (4).

  (1) Manure treatment agent containing slaked lime.

  (2) The excrement treating agent according to (1) above, further comprising at least one of a water-absorbing polymer and activated carbon.

  (3) The sewage treatment agent according to (1) or (2), wherein the slaked lime is surface-treated with a hydrophobic coating agent.

  (4) A manure processing method including a step of mixing the manure treating agent according to any one of (1) to (3) and manure.

  According to the excrement treating agent and the excrement treating method of the present invention, it is possible to treat a large amount of excrement easily and efficiently without requiring an operation such as stirring, and the processed material is hardly spoiled even after the treatment. It does not occur and the generation of malodor and gas can be suppressed.

  Still other objects, features and characteristics of the present invention will become apparent by referring to the following description and preferred embodiments illustrated in the accompanying drawings.

  Embodiments of the present invention will be described below.

  The excrement treating agent by this invention contains slaked lime, and may contain at least one of a water absorbing polymer and activated carbon as needed. Hereinafter, the components of the fecal treatment agent according to the present invention will be described in detail.

[Slaked lime]
Since slaked lime (Ca (OH) ₂ ) used in the present invention is a strong alkali, it has a large bactericidal effect during excrement treatment. Thereby, fermentation and decomposition | disassembly of organic substance can be stopped and the effect of reducing 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 a granular shape and a pellet shape. From the viewpoint of effectively dispersing the stool, the granular shape is preferable. Moreover, the average particle diameter is preferably in the range of 10 μm to 50 mm, and more preferably in the range of 50 μm to 1000 μm. When the average particle diameter of the slaked lime is less than 10 μm, production may be difficult and production cost may be increased. On the other hand, if it is larger than 50 mm, the contact area between the obtained excrement treating agent and excrement may be reduced and the reaction efficiency may be reduced. In addition, a lump may be generated during the excrement treatment, and unreacted matter may remain. is there. If necessary, the slaked lime may be used in combination of two or more slaked limes having different average particle sizes. In the present invention, the average particle diameter is a value measured by the method described in Examples below.

  It is preferable that content of the slaked lime in the excrement processing agent of this invention is 40-100 mass% with respect to the total mass of an excrement processing agent. If content of slaked lime is 40 mass% or more, the effect of the odor reduction at the time of excrement processing and suppression of gas generation will be acquired more favorably. The content is more preferably 65 to 100% by mass. Although the content of slaked lime may be 100% by mass, for example, it is more preferably 65-99.5% by mass, particularly preferably 75-99% by mass, and the balance makes the effects of the present invention more prominent. Therefore, it is also preferable to add at least one of the water-absorbing polymer and activated carbon described later to the sewage treatment agent of the present invention.

[Water-absorbing polymer]
When only slaked lime is used as the excrement treating agent, it may not be able to absorb the water in the excrement and become muddy. 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. The water-absorbing polymer used in the present invention can absorb water in manure and solidify manure. When slaked lime and a water-absorbing polymer are added to manure, the manure is solidified, and the solidified manure is surrounded by slaked lime so that the fermentation and decomposition activities of microorganisms can be stopped. Moreover, the addition amount of slaked lime can be reduced and the malodor which slaked lime itself emits can be reduced more.

  The water-absorbing polymer used in the present invention is not particularly limited as long as it does not adversely affect the manure treatment agent and manure treatment method of the present invention, and known substances can be used. Specific examples thereof include, for example, starch-based acrylonitrile graft polymer hydrolyzate, starch-based water-absorbing polymers such as starch-acrylic acid graft polymer, cellulose-acrylonitrile graft polymer, cellulose-styrene sulfonic acid graft copolymer. 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 Acrylic water-absorbing polymer such as a sodium partial polymer salt cross-linked product, sodium acrylate-vinyl alcohol copolymer, maleic anhydride water-absorbing polymer, vinyl pyrrolidone water-absorbing polymer, polyethylene glycol diac Polyether type water-absorbing polymer, such as rate 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 Aquakeep (registered trademark) SA (manufactured by Sumitomo Seika Co., Ltd.), Aquaric (registered trademark) CA (manufactured by Nippon Shokubai Co., Ltd.), and the like.

  Among these water-absorbing polymers, Aqua Keep (registered trademark) SA is more preferable.

  The shape of the water-absorbing polymer is not particularly limited, and examples thereof include a granular shape, a powder shape, a granular shape, and a pellet shape.

  The amount of water-absorbing polymer used can be adjusted as appropriate depending on the type and shape of the water-absorbing polymer and the amount of water contained in the manure that is to be treated. The range is preferably 0.5 to 30% by mass, more preferably 1 to 20% by mass, and still more preferably 5 to 15% by mass. When the amount used is less than 0.5% by mass, the effect of the water-absorbing polymer is hardly obtained, and the excreta may become muddy. On the other hand, when it exceeds 30 mass%, an unreacted water-absorbing polymer remains, and it may become uneconomical in cost.

[Activated carbon]
The activated carbon used in the present invention is added from the viewpoint of suppressing the malodor emitted by the slaked lime. Moreover, the activated carbon also has a function of suppressing malodor generated during the excreta treatment.

  The activated carbon used in the present invention is not particularly limited. Specific examples of the activated carbon include, for example, activated carbon obtained by a known method using, as raw materials, synthetic resin such as charcoal, coke, coconut husk, natural fiber, polyacrylonitrile, rayon, phenol resin, and the like. . These may be used alone or in combination of two or more. Moreover, the activated carbon may be synthesized or a commercially available product may be used. As an example of a commercial item, activated carbon GY alkali use, activated carbon GX acidic use (above, Toyobo Co., Ltd. product), or these mixtures are mentioned, for example.

  Furthermore, it is good also as a slaked lime component and activated carbon component of the excrement processing agent of this invention using the commercial item in which slaked lime and activated carbon are mixed previously, for example, Solvalit (made by Ube Materials Co., Ltd.).

  Among these activated carbons, sol barit is more preferable.

  The shape of the activated carbon is not particularly limited, and examples thereof include granule, powder, granule, pellet, macaroni, fiber, and honeycomb.

  The amount of activated carbon used can be adjusted as appropriate depending on the type and shape of the activated carbon and the amount of water contained in the manure that is the object to be treated. The range is preferably 5 to 30% by mass, more preferably 1 to 15% by mass, and further preferably 3 to 10% by mass. When the amount used is less than 0.5% by mass, the effect of activated carbon that suppresses malodor may be hardly obtained. On the other hand, when it exceeds 30 mass%, activated carbon becomes excessive and it may become uneconomical in cost.

In the present invention, zeolite such as K [AlSi ₂ O ₆ ] may be used instead of the activated carbon.

  The slaked lime used in the present invention is preferably surface-treated with a hydrophobic coating agent. By performing the surface treatment, it is possible to improve the storage stability of the excrement treating agent. Moreover, since the slaked lime surface-treated with the hydrophobic coating agent is slowly dissolved by the water in the urine, it is easy to sterilize the microorganisms in the urine and can increase the effect of suppressing malodor. Furthermore, since the manure after a process becomes a granular form, handling becomes easy.

  Specific examples of the hydrophobic coating agent include at least one compound selected from the group consisting of paraffin, stearylamine, higher fatty acids, salts of higher fatty acids, or esters of higher fatty acids. Among these, at least one compound selected from the group consisting of higher fatty acids, higher fatty acid salts, and higher fatty acid esters is preferable. Such higher fatty acids are preferably monovalent or polyvalent saturated fatty acids or unsaturated fatty acids having 8 to 26 carbon atoms, more preferably monovalent or polyvalent saturated fatty acids or unsaturated fatty acids having 8 to 24 carbon atoms, A monovalent saturated fatty acid of several 10 to 20 is particularly preferable. Specific examples of the higher fatty acids include caprylic acid, pelargonic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, lignoceric acid, oleic acid, linoleic acid, linolenic acid, arachidonic acid and the like. It is done. Specific examples of the higher fatty acid salts include ammonium salts; alkali metal salts such as sodium salts and potassium salts; and salts of Group 2 metals such as calcium salts and magnesium salts. Specific examples of the higher fatty acid ester include methyl ester, ethyl ester, n-propyl ester, isopropyl ester, n-butyl ester, sec-butyl ester, tert-butyl ester, isobutyl ester, n-hexyl ester and the like. Or a cycloalkyl ester such as a cyclohexyl ester.

  When the hydrophobic coating agent is used, the amount used is preferably in the range of 0.1 to 5% by mass, more preferably in the range of 0.3 to 2% by mass, based on slaked lime. More preferably, it is in the range of 5 to 1% by mass. When the amount of the coating agent used is less than 0.1% by mass, a sufficient reaction delaying effect cannot be obtained during the excrement treatment, the reaction proceeds rapidly, and uniform mixing cannot be performed. In addition to the formation, the hydrophobicity of the reaction product is not maintained, and there is a possibility that it returns to the original form of manure due to water mixing. On the other hand, if it exceeds 5% by mass, the active surface area of slaked lime decreases, so that the reaction may not proceed efficiently, and the cost may increase.

  When surface-treating slaked lime with a hydrophobic coating agent, the surface treatment method is not particularly limited as long as it does not adversely affect the manure treatment agent and manure treatment method of the present invention. Specifically, for example, in the state where quick lime is heated and at a temperature higher than the melting point of the coating, the hydrophobic coating is added, cooled to a predetermined temperature, and then water is added to cause a hydration reaction. Preferably, the method of making it is used. The surface-treated slaked lime may be used in combination of two or more kinds of slaked lime that has been surface-treated using different amounts of coating agent.

  The slaked lime surface-treated with the above hydrophobic coating agent may be synthesized or a commercially available product may be used.

  Moreover, the shape of the surface-treated slaked lime is not particularly limited, but is preferably granular. The particle size is not particularly limited, but is preferably about 100 mesh.

[Additive]
The manure treatment agent of the present invention may further contain other additives as long as they do not adversely affect the manure treatment agent and manure treatment method of the present invention. Examples of such additives include a fragrance, a deodorant, or a deodorizer from the viewpoint of odor control; a hydrophilic organic compound such as alcohol from the viewpoint of improving the wettability of the surface-treated slaked lime with respect to water, or Surfactant; From the viewpoint of controlling the water content in manure, desiccant such as silica gel and anhydrous sodium sulfate; From the viewpoint of sterilization and deodorization; Chlorine-containing compounds such as sodium hypochlorite; Alkaline conditions at the time of manure treatment From the viewpoint of complementing the above, hydroxides of Group 1 elements such as sodium hydroxide, sodium hydrogen carbonate (sodium bicarbonate) and the like can be mentioned. These additives may be used alone or in combination of two or more.

  Examples of the fragrances include lemon oil, lemon grass, cinnamon oil, lavender oil, and vetiver.

  Various surfactants can be used as the surfactant, and specific examples thereof include, for example, polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, polyoxyethylene monofatty acid ester, polyoxyethylene alkyl ester, Nonionic surfactants such as oxyethylene difatty acid ester, polyoxyethylene propylene glycol fatty acid ester, polyethylene sorbitan monofatty acid ester, glycerin monofatty acid ester; alkylbenzene sulfonate, alkyl sulfosuccinate, alkyl sulfate, polyoxyethylene alkyl sulfate , Anionic surfactants such as aryl sulfonates; long-chain primary amine salts, dialkyldimethylammonium salts, alkyltrimethylammonium salts, benzylates Ammonium chloride, alkylpyridinium salts, benzalkonium chloride, cationic surfactants such as benzethonium chloride; or alkyldiaminoethylglycine hydrochloride, and amphoteric surfactants such as hydrochloric alkylpolyaminoethylglycine is.

  Further, a sachet made of a water-soluble resin, a sachet made of water-soluble paper, or a sachet made of a water-degradable nonwoven fabric, which can be used when adding the sewage treatment agent to sewage, is also included in the sewage treatment agent of the present invention. It can be contained as an additive.

[Manure treatment agent]
The method for preparing the excrement treating agent of the present invention is not particularly limited, and for example, a method of mixing slaked lime and, if necessary, at least one of activated carbon and a water-absorbing polymer, and further mixing desired additives as necessary. Etc.

  As a method of mixing, each component may be mixed at once, or each component may be mixed sequentially.

[Manure disposal method]
Next, the excrement processing method using the excrement processing agent of this invention is explained in full detail.

  The excrement processing method of this invention has the process of mixing the excrement processing agent of this invention, and excrement.

  The manure applied to the manure processing method of the present invention includes not only human manure but also animal manure such as cow manure, pig manure, and chicken manure. Further, the stool may be stool alone, urine alone, or a mixture of stool and urine.

  The use amount of the excrement treating agent is preferably in the range of 15 to 200 parts by mass, more preferably in the range of 30 to 120 parts by mass, with respect to 100 parts by mass of excrement as the object to be processed. More preferably, it is 100 parts by mass. When the amount of the manure treatment agent used is less than 15 parts by mass, the contact area between the manure and slaked lime is reduced, so that the manure comes into contact with the air and the fermentation and decomposition of manure may progress. On the other hand, when it exceeds 200 mass parts, the residue after a process may increase and the waste after a process may increase. In addition, the cost may increase.

  Specific examples of the method for treating excrement of the present invention include, for example, a method of adding manure that is an object to be treated to the manure treating agent and allowing to stand, and a method for adding the manure treating agent to manure that is an object to be treated. Or a treatment method that does not include an agitation operation, such as a method of adding and mixing the sewage treatment agent and manure as the object to be treated at the same time and mixing them. Further, a method of sequentially adding each component of the excrement treating agent to the excrement and allowing to stand is also included in the excrement treating method of the present invention.

  Further, the manure treatment method of the present invention is a method in which, for example, the manure treatment agent is put in a wrapping bag in advance from the viewpoint of ease of handling and the sachet is added to the manure as it is during manure treatment. Also good. The wrapping bag in this case may be a wrapping bag made of a water-soluble resin, a wrapping bag made of water-soluble paper, or a wrapping bag made of a water-degradable nonwoven fabric so that the sewage treatment agent is efficiently diffused into the urine during sewage treatment. preferable. In addition, it is preferable to preserve | save the said excrement processing agent including these aspects on moisture-proof and water-resistant conditions.

  According to the excrement disposal method of the present invention, it is possible to suppress the generation of fever and bad odor during the treatment while leaving it stationary without requiring an operation such as stirring, and to safely and massively treat the excrement. It can be carried out.

  The feces and urine treatment agent of the present invention can be suitably used for uses such as treatment of a toilet for disaster, treatment of a simple toilet for care, treatment of vomit of an infectious disease patient, treatment of blood, and the like.

(Comparative example)
The water-absorbing polymer was used as it was as a manure treatment agent.

(Manure treatment test)
As a sample, 265 g of a mixture of stool, urine, and toilet paper was prepared.

  The specimen was placed in a Tokyo-designated garbage bag, and then a manure treatment agent was placed and the mouth was tied. Thereafter, it was allowed to stand at 25 ° C., and the odor and properties were observed after 1 day, 3 days, 1 week and 1 month. The results when using the feces and urine treating agents of Examples 1 to 19 and Comparative Example are shown in Table 1 and Table 2 below.

  As is apparent from Table 1 above, when the sewage treatment agent consisting only of the water-absorbing polymer of the comparative example was used, the odor and odor of stool did not disappear after the treatment, and the treatment became worse after one week. It was observed that the properties of the objects were corrupt.

  On the other hand, when the fecal urine treatment agent of the present invention of Examples 1 to 19 is used, the odor of stool, which is an object to be treated, is small, and particularly fecal urine of Examples 3 to 11, Examples 13 to 14, and Examples 16 to 19 When the treatment agent was used, almost no odor was felt.

Regarding the properties of the processed products, in particular, when the feces and urine treatment agents of Examples 3 to 5, Example 9, Examples 13 to 14, and Examples 16 to 18 were used, no stool shape remained. The photograph of the processed material after processing a manure with a processing agent and passing 1 month is shown to FIGS. 1 is a fecal urine treatment agent of Example 1, FIG. 2 is an excrement treatment agent of Example 2, FIG. 3 is an excrement treatment agent of Example 3, FIG. 4 is an excrement treatment agent of Example 4, and FIG. 6 was used as the fecal urine treatment agent of Example 16, and FIG. 7 was used as the fecal urine treatment agent of the comparative example. As can be seen from FIGS. 1 to 7, when the feces and urine treatment agents of Example 3, Example 4, Example 9, and Example 16 were used, no stool shape remained and the rot of the processed material almost progressed. It was n’t. On the other hand, when the sewage treatment agent of the comparative example was used, the shape of the stool was seen as it was, and the decay was progressing.

  From the above results, it can be seen that the manure treatment agent according to the present invention can treat manure by a simple method without stirring, and hardly generates odor even after the treatment.
