It was decided to produce fertilizer by mixing the agent with livestock dung and drying the livestock dung.

また、請求項６に係る本発明では、前記請求項５に係る本発明において、前記乾燥処理剤に硫酸カルシウムの１／２水和物（焼石膏）を添加することにした。   Further, in the present invention according to claim 6, in the present invention according to claim 5, calcium hemihydrate (calcined gypsum) is added to the drying treatment agent.

そして、本発明では、以下に記載する効果を奏する。   And in this invention, there exists an effect described below.

すなわち、本発明では、硫酸第一鉄と酸化カルシウムとを飽和状態まで反応させた後に過マンガン酸カリウムを添加して乾燥処理剤を生成しているために、この乾燥処理剤を含水物に混入させることによって、硫酸第一鉄、酸化カルシウム、過マンガン酸カリウムの存在下においてセメント固化に類似する反応が共生して起こり錯塩として水分を大量に取り込み、含水物を短時間で良好に脱水し乾燥させることができる。   That is, in the present invention, after the ferrous sulfate and calcium oxide are reacted to saturation, potassium permanganate is added to produce a drying treatment agent. In the presence of ferrous sulfate, calcium oxide, and potassium permanganate, a reaction similar to cement solidification occurs symbiotically, and a large amount of water is taken in as a complex salt, and the water-containing material is dehydrated and dried well in a short time. Can be made.

そのため、含水物として畜糞を用いた場合には、畜糞の乾燥を容易かつ短時間で行うことができ、しかも、乾燥処理物を肥料として有効に利用することができる。   Therefore, when livestock droppings are used as a hydrous material, drying of livestock droppings can be performed easily and in a short time, and the dried processed product can be effectively used as a fertilizer.

以下に、本発明に係る乾燥処理剤、及び乾燥処理剤を用いた畜糞の乾燥処理方法、並びに乾燥処理剤を用いて畜糞の乾燥処理を行うことによって肥料を製造する肥料の製造方法について具体的に説明する（図１参照。）。   Hereinafter, the drying treatment agent according to the present invention, the method for drying livestock excreta using the drying treatment agent, and the fertilizer production method for producing fertilizer by performing the drying treatment of livestock excrement using the drying treatment agent will be specifically described. (See FIG. 1).

本発明に係る乾燥処理剤は、硫酸第一鉄（FeSO4）と酸化カルシウム（CaO：生石灰）とを飽和状態まで反応させ、その後、過マンガン酸カリウム（KMnO4）を添加して生成したものである。 The drying treatment agent according to the present invention is produced by reacting ferrous sulfate (FeSO 4 ) and calcium oxide (CaO: quick lime) to saturation, and then adding potassium permanganate (KMnO 4 ). It is.

この乾燥処理剤では、硫酸第一鉄と酸化カルシウムとが既に飽和状態まで反応していることから、過マンガン酸カリウムを添加しても反応が進行しない状態となっている。   In this drying agent, since ferrous sulfate and calcium oxide have already reacted to saturation, the reaction does not proceed even when potassium permanganate is added.

この乾燥処理剤には、硫酸第一鉄と酸化カルシウムとを飽和状態まで反応させた後に、過マンガン酸カリウムの他に、硫酸カルシウムの１／２水和物（CaSO4・1/2H2O：焼石膏）やセメントや珪酸ナトリウム（Na2SiO3）を添加してもよい。 In this drying treatment agent, ferrous sulfate and calcium oxide are reacted to saturation, and then calcium sulfate ½ hydrate (CaSO 4 · 1 / 2H 2 O) in addition to potassium permanganate. : Calcined gypsum), cement or sodium silicate (Na 2 SiO 3 ) may be added.

この乾燥処理剤は、含水物である被乾燥処理物に混入させると、硫酸第一鉄、酸化カルシウム、過マンガン酸カリウムの存在下においてセメント固化に類似する反応が共生して起こり、被乾燥処理物に含有される多量の水分が直ちに分子水として取り込まれて水の錯体を形成して固化し、被乾燥処理物（含水物）を短時間で良好に脱水し乾燥させることができる。   When this drying treatment agent is mixed into a material to be dried, which is a hydrated material, a reaction similar to cement solidification occurs in the presence of ferrous sulfate, calcium oxide, and potassium permanganate. A large amount of water contained in the product is immediately taken in as molecular water to form a water complex and solidify, and the dried product (hydrated product) can be dehydrated and dried well in a short time.

特に、乾燥処理剤に硫酸カルシウムを添加した場合には、硫酸カルシウムが水分を取り込んで二水石膏となり、固化を促進させることができ、より一層短時間で乾燥処理することができる。   In particular, when calcium sulfate is added to the drying treatment agent, the calcium sulfate takes in moisture and becomes dihydrate gypsum, which can promote solidification and can be further dried in a shorter time.

また、乾燥処理剤に珪酸ナトリウムを添加した場合には、珪酸ナトリウムが加水分解されてアルカリ性となり、反応を促進させることができ、より一層短時間で乾燥処理することができる。   In addition, when sodium silicate is added to the drying treatment agent, the sodium silicate is hydrolyzed to become alkaline, the reaction can be promoted, and the drying treatment can be performed in a shorter time.

また、本発明に係る畜糞の処理システムは、上記乾燥処理剤を鶏糞などの家畜の畜糞に混入することによって畜糞を乾燥させるものである。   Moreover, the livestock excrement processing system which concerns on this invention dries livestock feces by mixing the said drying processing agent into livestock feces of livestock, such as chicken feces.

上記乾燥処理剤を畜糞に混入すると、畜糞の乾燥が行われるが、温度上昇はわずかであり、急激な温度上昇に伴う蒸散が生ずることがなく、したがって、畜糞に含まれるアンモニアによる悪臭が周囲に拡散してしまうことがない。しかも、畜糞に含まれるアンモニアによってアルカリ性となっており、反応が促進される。   When the above drying treatment agent is mixed in livestock feces, the livestock feces are dried, but the temperature rise is slight, and no transpiration is caused by the rapid temperature rise. There is no diffusion. In addition, the reaction is promoted by alkalinity due to the ammonia contained in the animal feces.

この畜糞の乾燥処理においても、乾燥処理剤に硫酸カルシウムを添加した場合には、硫酸カルシウムが水分を取り込んで二水石膏となり、固化を促進させることができ、より一層短時間で乾燥処理することができ、また、乾燥処理剤に珪酸ナトリウムを添加した場合には、珪酸ナトリウムが加水分解されてアルカリ性となり、反応を促進させることができ、より一層短時間で乾燥処理することができる。   Also in this animal manure drying treatment, when calcium sulfate is added to the drying treatment agent, calcium sulfate will take in moisture and become dihydrate gypsum, which can promote solidification and can be dried in a shorter time. In addition, when sodium silicate is added to the drying treatment agent, the sodium silicate is hydrolyzed to become alkaline, the reaction can be promoted, and the drying treatment can be performed in a shorter time.

さらに、本発明に係る畜糞の処理システムは、上記した畜糞の乾燥処理方法によって畜糞を乾燥させることで生成された固形物をそのまま肥料とするものである。なお、この肥料には、必要に応じて栄養素を添加してもよい。   Furthermore, the livestock excrement processing system according to the present invention uses the solid matter generated by drying livestock feces by the above-described livestock excretion drying method as it is as a fertilizer. In addition, you may add a nutrient to this fertilizer as needed.

すなわち、上記乾燥処理剤を鶏糞などの家畜の畜糞に混入すると、乾燥処理剤によって畜糞が乾燥して、固形状の肥料が得られるのである。   That is, when the drying treatment agent is mixed in livestock excrement of livestock such as chicken droppings, the animal droppings are dried by the drying treatment agent and solid fertilizer is obtained.

このようにして製造された肥料は、乾燥処理により畜糞が軽量化及び減容化されているため、畜糞を運搬して別の場所で製造するよりも短時間かつ低コストで製造することができる。   The fertilizer manufactured in this manner can be manufactured in a shorter time and at a lower cost than that of transporting livestock dung and manufacturing it elsewhere because the livestock dung has been reduced in weight and reduced in volume by drying treatment. .

この飼料の製造方法においても、乾燥処理剤に硫酸カルシウムを添加した場合には、硫酸カルシウムが水分を取り込んで二水石膏となり、固化を促進させることができ、より一層短時間で肥料を製造することができ、また、乾燥処理剤に珪酸ナトリウムを添加した場合には、珪酸ナトリウムが加水分解されてアルカリ性となり、反応を促進させることができ、より一層短時間で肥料を製造することができる。   Also in this feed production method, when calcium sulfate is added to the drying treatment agent, the calcium sulfate takes in water to form dihydrate gypsum, which can promote solidification and produce fertilizer in a shorter time. In addition, when sodium silicate is added to the drying treatment agent, the sodium silicate is hydrolyzed to be alkaline and the reaction can be promoted, and a fertilizer can be produced in a shorter time.
