Description
本発明は家畜糞堆肥に係り、特に、家畜糞を用いて製造された家畜糞堆肥に関する。 The present invention relates to livestock manure compost fertilizer, particularly, relates to a granulated Homes dung compost fertilizer manufactured using livestock manure.
牛糞,豚糞,鶏糞等の家畜糞を堆肥化する方法が広く知られている(例えば、特許文献1)。
特許文献1の堆肥製造方法では、鶏糞に木片チップと微生物を混入した60℃以上の混合物を、堆肥舎で6.5日間、その後発酵槽で23.5日間発酵させる。得られた発酵物から、選別機で木片チップを回収した後、鶏糞堆肥を養生施設に送り、切返しをしながら60℃以上で3.8日間発酵させて、鶏糞堆肥が完成する。
このように製造された家畜糞堆肥は、低コストなだけでなく、含有するリン酸の殆どが、植物の根から分泌される有機酸により溶解・吸収される緩効性で、土壌に固定されにくく持続性ある水不溶クエン酸溶性リン酸であって、化成肥料のリン酸と同様以上の高い肥効を示す。
A method of composting livestock feces such as cattle feces, pig feces and chicken feces is widely known (for example, Patent Document 1).
In the method for producing compost of Patent Document 1, a mixture of wood chips and microorganisms mixed with chicken manure is fermented at 60 ° C. or more for 6.5 days and then in a fermenter for 23.5 days. From the obtained fermented material, chip chips are collected by a sorter, and then the chicken manure compost is sent to a curing facility and fermented at 60 ° C. or higher for 3.8 days while being turned over to complete the chicken manure compost.
Livestock manure compost produced in this way is not only low in cost, but also has a slow release, in which most of the phosphoric acid contained is dissolved and absorbed by organic acids secreted from the plant roots, and is fixed to the soil. It is a difficult and long-lasting water-insoluble citric acid-soluble phosphoric acid, and exhibits a high fertilizing effect similar to the phosphoric acid of chemical fertilizer.
また、家畜糞堆肥は、毎日膨大な量が発生し廃棄物となるべき家畜糞をリサイクルするものであって、畜産業側の廃棄コストを大幅に削減すると同時に、耕種側でも、高価な化成リン酸肥料の代替品となるため、畜産業側,耕種側双方の大幅なコスト削減につながるものである。
更に、天然資源であるリン鉱石は枯渇の危機に瀕しており、リン鉱石をほぼ全量輸入に依存しているわが国において、リン資源の確保は重要な課題となっている中、化成肥料と同様以上の肥効を示し、リン酸を含有する家畜糞堆肥は、化成肥料の代替品として益々重要度を増している。
In addition, livestock manure compost recycles livestock manure, which is generated in large amounts every day and should become waste. It greatly reduces the disposal costs on the livestock industry side, and at the same time, it is an expensive chemical phosphorus on the farming side. Since it becomes a substitute for acid fertilizer, it leads to significant cost reduction on both the livestock industry side and the farming side.
In addition, phosphorus ore, which is a natural resource, is on the verge of depletion, and in Japan, which depends on almost all imports of phosphorus ore, securing phosphorus resources is an important issue. Livestock manure compost showing the above-mentioned fertilization effect and containing phosphoric acid is becoming increasingly important as a substitute for chemical fertilizer.
しかし、特許文献1記載の堆肥製造方法によれば、家畜糞堆肥の完成までに1か月以上を要し、その間、大量の家畜糞を保管,処理する施設が必要となる。近年の大規模農業化に伴い増大化した家畜糞に対して堆肥化が間に合わず、一方、家畜糞を野積みにすると、地下水が汚染される恐れがあるため、条例等によって野積みが禁止されている。家畜糞の処理は、農場経営における課題となっている。
更に、長期間の家畜糞堆肥製造中及び耕種側での堆肥使用中において、悪臭による環境悪化の懸念もある。家畜糞処理時の悪臭を抑制するために、脱臭剤を使用する方法もあるが、悪臭を完全に元から取り除く脱臭剤は知られていない。
However, according to the compost production method described in Patent Document 1, it takes one month or more to complete livestock manure compost, and a facility for storing and processing a large amount of livestock manure is required during that period. Composting is not in time for livestock excrement that has increased in recent years due to large-scale agriculture. On the other hand, if livestock excrement is piled up, groundwater may be contaminated. ing. The treatment of livestock dung is a challenge in farm management.
Furthermore, there is a concern that the environment deteriorates due to bad odor during long-term production of livestock manure compost and compost use on the cultivated side. There is a method of using a deodorizing agent in order to suppress malodors during the treatment of livestock excrement, but no deodorizing agent that completely removes malodors from the original is known.
本発明は、上記事情に鑑みてなされたものであって、その目的は、家畜糞から短期間で糞臭なく製造できる家畜糞堆肥を提供することにある。
本発明の他の目的は、堆肥製造中及び完成後において悪臭のない家畜糞堆肥を提供することにある。
The present invention was made in view of the above circumstances, an object thereof is to provide a home dung compost fertilizer that can fecal odor without Manufacturing shortly after livestock manure.
Another object of the present invention is to provide a name has house dung compost fertilizer odor during composting and after completion.
前記課題は、請求項1の家畜糞堆肥によれば、含有窒素量の2倍以上の量で、かつ、含有カリウム量の2倍以上の量のリン酸を含み、フェリハイドライトと家畜糞中の有機物との複合体を含む糞臭のない家畜糞堆肥により解決される。
このように、フェリハイドライトと家畜糞中の有機物との複合体を含むため、家畜糞中の有機物がアルミニウム、マグネシウム等の他の元素と複合体を形成してしまうことを防止できる。家畜糞中の有機物との複合体を、生体や生態系に悪影響を及ぼす可能性が極めて小さい鉄を含むものとすることが可能となるのである。さらに、フェリハイドライトを含む複合体は、反応が起こる表面積が大きく、またpH変化によって起こる変異荷電特性に起因する物理化学反応力が大きい。
また、フェリハイドライトは、酸素吸着による酸化防止効果、肉類の鮮度保持効果、嫌気性菌の繁殖抑制による抗菌・制菌効果等を有することが知られており、本実施形態によりできた家畜糞中の有機物とフェリハイドライトとの複合体は、これらの効果をも奏する。
更に、家畜糞中の有機物が、フェリハイドライドとの複合体を形成することにより、堆肥中のリン酸等の肥料成分が溶脱し難く、安定した堆肥とすることができる。
このとき、pH8以下で、木材チップを含む水分調整材を含有しないと好適である。
このように構成しているので、家畜糞堆肥がアルカリ性のときに生じるみそ臭のない家畜糞堆肥とすることができる。従って、家畜糞処理剤による糞臭の除去のみでなく、本発明の家畜糞堆肥がアルカリ性になったときに生じる独特のみそ臭も抑えることができる。
The object is achieved, according to the livestock manure compost according to claim 1, in an amount at least twice the nitrogen content, and includes a phosphate of 2 times the amount of content potassium content, ferrihydrite and livestock feces It is solved by livestock manure compost that does not contain feces odor and contains a complex with organic matter.
Thus, since the composite of ferrihydrite and organic matter in livestock feces is included, it is possible to prevent the organic matter in livestock feces from forming a composite with other elements such as aluminum and magnesium. The complex with the organic matter in livestock feces can contain iron that has a very low possibility of adversely affecting the living body and the ecosystem. Furthermore, the complex containing ferrihydrite has a large surface area where the reaction occurs, and also has a large physicochemical reaction force due to the mutated charge characteristics caused by the pH change.
In addition, ferrihydrite is known to have an antioxidant effect due to oxygen adsorption, a meat freshness retaining effect, an antibacterial and antibacterial effect due to the inhibition of anaerobic bacterial growth, and the like. The complex of the organic substance and ferrihydrite therein also has these effects.
Furthermore, when the organic matter in livestock feces forms a complex with ferrihydride, fertilizer components such as phosphoric acid in the compost are not easily leached and stable compost can be obtained.
At this time , it is preferable that the pH is not more than 8 and the moisture adjusting material including the wood chip is not included .
Since it comprises in this way, it can be set as the livestock manure compost without the miso odor produced when livestock manure compost is alkaline. Therefore, not only the removal of the feces odor by the livestock feces treatment agent but also the unique odor generated when the livestock manure compost of the present invention becomes alkaline can be suppressed.
本発明によれば、フェリハイドライトと家畜糞中の有機物との複合体を含むため、家畜糞中の有機物がアルミニウム、マグネシウム等の他の元素と複合体を形成してしまうことを防止できる。家畜糞中の有機物との複合体を、生体や生態系に悪影響を及ぼす可能性が極めて小さい鉄を含むものとすることが可能となるのである。さらに、フェリハイドライトを含む複合体は、反応が起こる表面積が大きく、またpH変化によって起こる変異荷電特性に起因する物理化学反応力が大きい。

また、家畜糞処理液に含まれる高分子の径は、3〜8(nm)程度である。
House dung processing liquid, iron (Fe) as a main component, other manganese (Mn), magnesium (Mg), including cations such as calcium (Ca). However, the sum of the amount of magnesium and the amount of calcium is less than 30% by weight of the amount of iron contained in the mineral liquid.
The livestock dung treatment liquid contains about 7000 to 15000 (ppm) of iron, and the pH is about 0.1 to 0.2.
Moreover, the diameter of the polymer contained in the livestock feces treatment liquid is about 3 to 8 (nm).
家畜糞処理液に含まれる鉄は、pHによって異なる形態で存在する。pH3以下では、鉄は、Fe3+、pH3〜pH4では、Fe3+とFe(OH)2 +、pH4〜pH5では、Fe3+とFe(OH)2+とFe(OH)2 +、pH5より高いpHでは、Fe(OH)2+とFe(OH)2 +とFe(OH)3として存在する。 Iron contained in the house animal feces treatment liquid is present in different forms by pH. The pH3 or less, iron, Fe 3 +, in PH3~pH4, the Fe 3+ and Fe (OH) 2 +, pH4~pH5 , higher than the Fe 3+ and Fe (OH) 2+ and Fe (OH) 2 +, pH5 In pH, it is present as Fe (OH) 2+ and Fe (OH) 2 + and Fe (OH) 3.

4Fe(OH)3+8H+→4Fe2++10H2O+O2・・・(化学式1)
House dung processing solution has a deodorant sterilization effect.
This is considered to be because a ferrihydrite complex is formed from Fe (OH) 3, and when the complex is formed, the aromatic ring or —SH group of the organic substance is cleaved to remove feces odor.
Further, it is considered that the odorous substance is oxidatively decomposed by superoxide generated when iron of the main component Fe (OH) 3 at pH 5 or higher of the livestock manure treatment solution reacts to become divalent by the following chemical formula (1). .
4Fe (OH) 3 + 8H + → 4Fe 2+ + 10H 2 O + O 2 (Chemical formula 1)
また、一般的に、酸化状態では、O2が電子受容体となるため、酸化状態における有機物の最終産物はCO2とH2Oであるが、還元状態では、NO3,SO4,CO2が電子受容体となるため、有機物の最終産物としてN2,H2S,CH4も発生する。
式1の反応の酸化還元電位は、EH=―0.183Vであり、メタンガスの発生する電位はEH=―0.253Vであるため、嫌気状態になるのを防ぎ、メタンガス等の発生を抑制する。
In general, since O 2 becomes an electron acceptor in an oxidized state, the final products of organic substances in the oxidized state are CO 2 and H 2 O. In the reduced state, NO 3 , SO 4 , CO 2 Becomes an electron acceptor, and N 2 , H 2 S, and CH 4 are also generated as a final product of organic matter.
Since the oxidation-reduction potential of the reaction of Formula 1 is EH = −0.183 V and the potential generated by methane gas is EH = −0.253 V, it prevents an anaerobic state and suppresses the generation of methane gas and the like. .
(家畜糞堆肥の製造方法)
本実施形態の家畜糞堆肥の製造方法について、鶏糞を用いて鶏糞堆肥を製造する場合を例として説明する。
まず、家畜糞処理液を、水で10倍〜3000倍に希釈し、pH5以上、好ましくはpH5〜6の希釈液を得る。このとき、同じ倍率で希釈しても、希釈に用いる水の種類によって得られる希釈液のpHが変化するが、本実施形態では、純水を用いる。
次いで、採卵鶏の鶏糞を準備する。採卵鶏の鶏糞としては、pH5以上のものを用いる。なお、鶏の腸内pHを下げるよう腸内pH調整を行わなければ、採卵鶏の鶏糞のpHは通常6前後であり、そのまま用いることができる。鶏糞のpHが5未満の場合、pH5以上に調整する。
(Manufacturing method of livestock manure compost)
About the manufacturing method of livestock manure compost of this embodiment, the case where chicken manure compost is manufactured using chicken manure is explained as an example.
First, the livestock excrement treatment solution is diluted 10 to 3000 times with water to obtain a diluted solution of pH 5 or more, preferably pH 5 to 6. At this time, even if it is diluted at the same magnification, the pH of the diluted solution obtained varies depending on the type of water used for dilution. In this embodiment, pure water is used.
Next, chicken droppings of the egg-collecting chicken are prepared. As chicken droppings of the egg-collecting chicken, one having a pH of 5 or more is used. If the intestinal pH is not adjusted to lower the intestinal pH of the chicken, the pH of the chicken manure of the egg-laying chicken is usually around 6, and can be used as it is. If the pH of the chicken manure is less than 5, adjust to pH 5 or higher.
家畜糞処理液は、pH5未満では、Fe(OH)3が存在せず、Fe3+とFe(OH)2+とFe(OH)2 +の形態となる。Fe3+とFe(OH)2+とFe(OH)2 +の形態のときには、鶏糞中の有機物は、鉄ではなくアルミニウム、マグネシウム、カルシウム等の他の元素と複合体を形成してしまうため、鉄と有機物との複合体であるフェリハイドライトができない。したがって、フェリハイドライトを形成させるためには、家畜糞堆肥製造方法の各工程において、鶏糞と家畜糞処理液の希釈液を混合したもののpHが、5以上になっていることが必要である。 Livestock manure treatment liquid, is less than pH 5, there is no Fe (OH) 3, the Fe 3+ and Fe (OH) 2+ and Fe (OH) 2 + form. Because when the Fe 3+ and Fe (OH) 2+ and Fe (OH) 2 + mode, the organic matter in the manure is aluminum rather than iron, magnesium, resulting in formation of other elements and complexes such as calcium, iron Ferrihydrite, which is a complex of organic and organic matter, is not possible. Therefore, in order to form ferrihydrite, it is necessary that the pH of the mixture of the chicken feces and the diluted livestock feces treatment solution is 5 or more in each step of the method for producing livestock manure compost.
次いで、採卵鶏の鶏糞1kg当たり0.2〜1.5Lの希釈液を、公知のスプレーを用いて鶏糞に散布する添加工程を行った後、5〜15分間撹拌混合する撹拌工程を行い、鶏糞と処理液の混合物を得る。なお、希釈液の添加量は、鶏糞の水分量に応じて決められる。また、添加工程は、スプレーを用いた散布に限られず、希釈液をそのまま注入したり、振り掛けたりしてもよい。
混合物をシート上に薄く広げ、5〜14日間天日干しにより、水分が10〜25%程度になるよう乾燥する乾燥工程を行い、乾燥混合物を得る。ここで、天日干しの日数を5日以上としたのは、5日未満であると、家畜糞特有の臭気が完全に除去されないためである。また、14日間以下としたのは、14日間天日干しすれば家畜糞特有の臭気が略完全に除去されるためである。また、14日より長い日数天日干しをすると、鶏糞の処理効率が低下し、処理待ちの鶏糞を保管する施設を大型化する必要が生じるためである。
なお、本実施形態では、天日干しにより乾燥工程を行うが、コンベア式乾燥機,ドラム式乾燥機等の乾燥機で乾燥してもよい。
乾燥混合物を粉砕して粉砕物を得て、家畜糞堆肥を完成する。
Subsequently, after performing the addition process which spreads 0.2-1.5L dilution liquid per kg of egg droppings of egg-laying chicken to chicken droppings using a well-known spray, the stirring process which stirs and mixes for 5 to 15 minutes is performed, chicken droppings And a mixture of the treatment liquid is obtained. In addition, the addition amount of a dilution liquid is determined according to the water content of chicken manure. Moreover, an addition process is not restricted to spraying using a spray, You may inject | pour dilution liquid as it is or sprinkle it.
The mixture is thinly spread on a sheet and dried in the sun for 5 to 14 days so that the water content is about 10 to 25% to obtain a dry mixture. Here, the reason why the number of sun-dried days is set to 5 days or more is that if it is less than 5 days, the odor peculiar to livestock droppings is not completely removed. The reason why the period is 14 days or less is that the odor peculiar to livestock excrement is almost completely removed by drying in the sun for 14 days. Moreover, if it is sun-dried for days longer than 14 days, the processing efficiency of chicken manure will fall, and it will be necessary to enlarge the facility which stores the chicken manure waiting for processing.
In the present embodiment, the drying process is performed by sun drying, but drying may be performed by a dryer such as a conveyor dryer or a drum dryer.
The dried mixture is pulverized to obtain a pulverized product, thereby completing livestock manure compost.
本実施形態の家畜糞堆肥を製造する方法では、家畜糞処理液の希釈液のpHを5以上に調整し、かつ、pH5以上の鶏糞を用いているため、以降の工程において、家畜糞処理液の希釈液のpHを5以上に保持することが可能となり、家畜糞処理液の希釈液中に、フェリハイドライトの原料となるFe(OH)3(水酸化鉄)を存在させることが可能となる。 In the method for producing livestock manure compost of this embodiment, the pH of the diluted solution of the livestock feces treatment liquid is adjusted to 5 or more, and chicken feces having a pH of 5 or more are used. It is possible to maintain the pH of the dilute solution at 5 or higher, and it is possible to make Fe (OH) 3 (iron hydroxide) as a raw material for ferrihydrite exist in the dilute solution of the livestock feces treatment solution. Become.
(家畜糞堆肥)
上記家畜糞堆肥の製造方法により製造された鶏糞堆肥は、緑色から黒色の粉末からなり、粉末状の家畜糞堆肥製品の形態においても、粉末に水を加えたペースト状の形態においても、従来の家畜糞堆肥特有の悪臭がない。
また、鶏糞堆肥は、pH8以下であるとよい。pH8より高くなると、独特のみそ臭が生じる場合があるが、pH8以下になると、このみそ臭が和らげられるか、なくなるためである。
なお、鶏糞堆肥は、鶏に与えた飼料,水や、鶏の生育した環境などにより、組成や性質が変化するため、鶏糞堆肥のpHが同じであっても、みそ臭が生じる場合も生じない場合もあり、みそ臭の発生頻度が異なる。鶏糞堆肥がpH6以下となると、どのような条件でも、ほぼ完全にみそ臭の発生が防止される。
(Livestock manure compost)
The chicken manure compost produced by the above method for producing livestock manure compost is composed of a green to black powder. There is no odor peculiar to livestock manure compost.
Further, the chicken manure compost is preferably pH 8 or less. When the pH is higher than 8, a unique miso odor may be generated. However, when the pH is 8 or less, the miso odor is relieved or eliminated.
In addition, because the composition and properties of chicken manure compost change depending on the feed, water, and the environment in which the chicken grew, etc., even if the pH of the chicken manure compost is the same, no miso odor is produced. In some cases, the frequency of miso odor is different. When the chicken manure compost has a pH of 6 or less, the occurrence of miso odor is almost completely prevented under any conditions.

家畜糞処理液を水で5倍希釈した希釈液1Lを、対比例1で用いたものと同じ採卵鶏の鶏糞10kgに散布して、水分60%とし、10分間撹拌混合した後、数分間放置して、鶏糞と処理液の混合物を得た。混合物をシート上に薄く広げ、7日間天日干しをして、乾燥混合物を得た。次いで、混合乾燥物を粉砕して粉砕物を得て、家畜糞堆肥を完成した。
得られた家畜糞堆肥は、pH8.03で、若干のみそ臭があったが、肥料臭気としては、合格品として許容される程度であった。
Example 9
1 L of diluted solution of livestock dung treatment solution diluted 5 times with water is sprayed on 10 kg of chicken dung of the same egg-laying hen used in the proportional 1 to make the moisture 60%, and stirred and mixed for 10 minutes, then left for several minutes Thus, a mixture of chicken manure and treatment liquid was obtained. The mixture was thinly spread on a sheet and sun-dried for 7 days to obtain a dry mixture. Next, the mixed dried product was pulverized to obtain a pulverized product, thereby completing livestock manure compost.
The obtained livestock manure compost had a pH of 8.03 and had a slight odor, but the fertilizer odor was only acceptable as an acceptable product.
(試験例2)
実施例6〜9で製造した鶏糞堆肥について、pHと臭気との関連を検討した。
実施例8,9より、家畜糞処理液で処理した鶏糞堆肥は、pH7.56,pH8.03で若干のみそ臭があったが、許容できる程度のわずかなみそ臭であった。従って、pH8以下程度で、アルカリ性の家畜糞堆肥特有のみそ臭がなくなることが分かった。
また実施例6,7より、家畜糞処理液で処理した鶏糞堆肥は、pH5.54,pH5.17で、全くの無臭になっていた。
実施例6〜9では、家畜糞処理液により、中性又は酸性の鶏糞堆肥となっており、アルカリ特有の悪臭がしないことが確認された。臭気の確認をしたところ、アンモニアの発生も抑えられており、真の発酵食品と同程度の系に入っているものと思われた。
(Test Example 2)
Regarding the chicken manure compost produced in Examples 6 to 9, the relationship between pH and odor was examined.
From Examples 8 and 9, chicken manure compost treated with the livestock manure treatment solution had a slight odor at pH 7.56 and pH 8.03, but a slight miso odor that was acceptable. Accordingly, it has been found that the odor is unique only to alkaline livestock manure compost at a pH of about 8 or less.
Further, from Examples 6 and 7, the chicken manure compost treated with the livestock manure treatment solution had pH 5.54 and pH 5.17 and was completely odorless.
In Examples 6-9, it became neutral or acidic chicken manure compost with livestock manure treatment liquid, and it was confirmed that there is no malodor peculiar to alkali. When the odor was confirmed, the generation of ammonia was suppressed, and it seemed that it was in the same system as the true fermented food.
