【発明の属する技術分野】
本発明は、汚泥・汚水を科学物質でなく、天然物のリサイクル利用で、土の再生、水の浄化を可能にし、併せて、環境を汚染しない農業及び緑化を行なう請求項１記載の再生土水資材及び施工方法
【０００２】
【従来の技術】
汚泥は極一部焼き物やコンクリートブロックの原料に使用する試みがあったが、多くはコスト高になり、中止の運命をたどっていた。大量に浚渫される汚泥の多くは産業廃棄物として、高いコストをかけ処分することを余儀なくされていた。汚水は、化学品である凝集剤を使ったり、濾過したりしていたが、コスト高になり又、悪臭を除くことが出来ず、多くは無残にも汚水のまま放置されていた。
【０００３】
【発明が解決しようとする課題】
大量に浚渫される汚泥を低コストで処理し、廃棄するのでなく、有効に再利用すること。
【０００４】
今日、日本の河川湖沼の多くは、汚水の溜り場となっている。低コストで大量浄化を可能にし、リサイクル利用により、水資源を確保する必要にせまられている。融雪剤の使用・海水の飛散・化学肥料の使いすぎ・連作等による塩障害・肥料農薬の流亡のない環境保全型の農業緑化及び農薬を使用しない芝生管理等、多くの課題があった。
【０００５】
【課題を解決するための手段】
本発明は、化学合成品を使用することなく、天然物のリサイクル利用により安価に且つ、大量の汚泥・汚水を再生させ、又、不良土壌を良質土に改質して植栽土とする。
【０００６】
すなわち、本発明は下記の再生土水用資材及び施工方法に係るものである。
１．不朽性天然繊維・燃焼灰を用いてなる、汚泥・土壌・汚水を再生するための再生土水用資材。
２．不朽性天然繊維質が、青森ヒバ・スギ・ヒノキ・ユーカリの樹木又は樹皮粉砕品、古紙・製紙工程で短繊維化した粕の一種以上より成る１記載の再生土水資材。
３．燃焼灰が汚泥・草木類・動物・石炭・石油を燃焼して得た灰である１又は２記載の再生土水用資材。
４．鹿沼土の粉を含むことを特徴とする１〜３のいずれかに記載の再生土水用資材。
５．汚染した水を、不朽性天然繊維に燃焼灰を含むものに接触させ、又は不朽性天然繊維に燃焼灰を含む濾材で濾過して、水を浄化する施工方法。
６．汚泥に、不朽性天然繊維単独若しくは燃焼灰を含むものを混合し、又はサンドイッチ状に交互に敷き、汚泥を造成土・植栽土壌に再生する施工方法。
７．塩類・有害物で汚染した土に、不朽性天然繊維単独若しくは燃焼灰を含むものを混合し、又はサンドイッチ状に交互に敷き、塩類・有害物で汚染した土を造成土・植栽土壌に再生する施工方法。
８．植栽土壌に、不朽性天然繊維単独若しくは燃焼灰を含むものを混合し、又はサンドイッチ状に交互に敷き、又は植栽地の下部の溝若しくは溜マスに不朽性天然繊維単独若しくは燃焼灰を含むものを設置し、肥料・農薬の流亡を抑制する施工方法。
【０００７】
不朽性天然樹皮は、青森ヒバ・スギ・ヒノキ及びユーカリの樹皮を粉砕して、繊維状にして用いる。しかし、これら特定の樹木は、枝とか用材をとった廃材の粉砕品（粉）、又はこれらの樹木のオガ粉も使用出来る。多くの場合、これら樹木の粉、オガ粉は、初期の効果は高いが効果が短いため、速効的に、又、補助的に使用されるケースが多い。樹皮の粉砕度は用途により若干異なるが、繊維のサイズは０．０２〜１０ｃｍ、好ましくは０．１〜３ｃｍである。汚泥の再生には、汚泥に不朽性天然繊維を５〜３００％好ましくは１０〜２００％配合するのが望ましい。燃焼灰は０〜３０％、好ましくは０〜２０％である。目土・植栽土・吹付資材・土壌改良資材には、不朽性天然樹皮・燃焼灰を加え、鹿沼土の微粉を１〜３０％、好ましくは５〜２０％加えるのが望ましい。鹿沼土のサイズは通常鹿沼土として使用出来ない微粉程よく、好ましくは、１６メッシュ以下である。
【０００８】
【作用】
不朽性天然繊維は、長期に腐敗しないため、汚泥の排水性を長期に確保し、泥化性が改良され、公園等の埋め立て土として再利用が出来る。その上、これら天然繊維は汚泥の気相率を高め、殺菌力・殺虫力があり、汚泥中の有害病害虫を抑制し、植栽用水及び土としても再利用出来る。
【０００９】
汚水・汚泥中に有害物質・悪臭を伴う時、不朽性繊維と燃焼灰の組合せは特に有効で、これら害を有効に固定し、除去し得る。汚水の浄化にも殺菌・殺藻・殺虫力は有効で、汚水中の有害病害虫を防ぎ、腐敗せず繊維状を保つことは、フィルターとして使用した時、濾過材として有効である。例えば、 底部に排水孔を有する槽に、不朽性天然繊維及び燃焼灰を敷き、その上より徐々に汚水を注ぎ、濾過し、悪臭を防ぎ、殺菌し乍ら水を浄化する。さらに、浄化した水を元にもどし、連続 回汚水地を浄化してもよい。また、不朽性天然繊維及び燃焼灰を厚さ２ｃｍにつけ濾布として、加圧、又は、減圧方式で汚水を浄化する。
【００１０】
又、融雪剤を頻繁に散布される降雪地帯の滑走路、道路沿いの緑地帯、さらには、海岸線沿いの緑地帯・農地は塩害を受け易い。塩害を受けると、従来は土壌を取り替える必要があったが、本発明によると、土を取り替える必要なく、本発明の資材を塩害の発生した土壌にすき込むのみで塩害の土壌を再生することが出来る。
【００１１】
今日、農業も河川汚染の原因といわれるのは、施用した肥料の８０〜９０％、農薬の３０〜７０％は未利用のまま河川に流亡しているが、本発明によると、この農薬・肥料の流亡を防止する。そのメカニズムは十分に解明されていないが、農薬・肥料を取込み、又、表層土に集積するのを防ぎ、降雨によるタレ流しを阻止している。既に、植栽されている芝地には、芝床土に混入することはできないため、砂又は土に本発明資材を混合し、目土として施用する。又、植栽土・吹付資材・土壌改良資材としても使用出来る。水車は、観光資源として大切なもので、水車の中に本発明資材を組込み、観光資源としながら、水を浄化することが出来る。具体的には、再生資材を、有孔体で形成された側面底面のボックスを有する水車に組み込んで、水車を廻しながら、汚水を浄化する。

BACKGROUND OF THE INVENTION
The reclaimed soil according to claim 1, wherein sludge / sewage is not a scientific substance, but can be regenerated and purified by recycling natural products, and at the same time, agriculture and revegetation are performed without polluting the environment. Water material and construction method
[Prior art]
There was an attempt to use sludge as a raw material for pottery and concrete blocks, but many were costly and were destined to be canceled. Many of the sludge drowned in large quantities was forced to dispose of as industrial waste at high costs. The sewage used a chemical flocculant or was filtered, but the cost was high and the bad odor could not be removed, and many were left untreated.
[0003]
[Problems to be solved by the invention]
Treat sludge that is drowned in large quantities at low cost and reuse it effectively rather than discarding it.
[0004]
Today, many rivers and lakes in Japan are sewage pools. Mass purification is possible at low cost, and it is necessary to secure water resources through recycling. There were many problems such as the use of snow-melting agents, the scattering of seawater, the excessive use of chemical fertilizers, salt damage due to continuous cropping, environmental conservation-type agricultural revegetation without the loss of fertilizer pesticides, and lawn management without the use of pesticides.
[0005]
[Means for Solving the Problems]
The present invention makes it possible to regenerate a large amount of sludge and sewage at a low cost by recycling natural products without using a chemically synthesized product, and to improve a poor soil to a high quality soil to obtain a planting soil.
[0006]
That is, the present invention relates to the following materials for reclaimed soil and construction methods .
1 . A material for reclaimed soil and water that regenerates sludge, soil, and sewage using enduring natural fibers and combustion ash.
2 . 2. The reclaimed soil and water material according to 1, wherein the immortal natural fiber comprises at least one of Aomori hiba, cedar, cypress, eucalyptus tree or bark pulverized product, and waste paper shortened in waste paper and papermaking processes.
3 . The material for reclaimed soil water according to 1 or 2, wherein the combustion ash is ash obtained by burning sludge, vegetation, animals, coal, and oil.
4 . The material for reclaimed soil water according to any one of 1 to 3 , which comprises Kanuma soil powder.
5 . A construction method for purifying water by bringing contaminated water into contact with an immortal natural fiber containing combustion ash, or filtering with a filter medium containing combustible ash in an immortal natural fiber.
6 . A construction method in which sludge is mixed with immortal natural fibers alone or containing burned ash, or is alternately laid in a sandwich shape to regenerate sludge into created soil or planting soil.
7 . Mix soil that is contaminated with salt / hazardous substances into immortal natural fibers or those containing combustion ash, or lay them alternately in a sandwich shape to regenerate soil contaminated with salts / hazardous substances into planted and planted soil. Construction method to do.
8 . Mix planted soil with immortal natural fibers alone or those containing burning ash, or lay them alternately in a sandwich, or include immortal natural fibers alone or burning ash in the lower grooves or pools of planted land A construction method that installs things and controls the loss of fertilizers and pesticides.
[0007]
The immortal natural bark is used by pulverizing the bark of Aomori Hiba, Sugi, Hinoki and Eucalyptus to form a fiber. However, these specific trees can be used as pulverized products (powder) of waste materials obtained from branches or timber, or sawdust of these trees. In many cases, these tree powder and sawdust have a high initial effect but are short in effect, so they are often used quickly or supplementarily. Although the degree of bark crushing varies slightly depending on the application, the fiber size is 0.02 to 10 cm, preferably 0.1 to 3 cm. In order to regenerate sludge, it is desirable to add 5 to 300%, preferably 10 to 200%, of immortal natural fibers in the sludge. Combustion ash is 0 to 30%, preferably 0 to 20%. It is desirable to add indestructible natural bark and combustion ash to the joint soil / planting soil / spraying material / soil improving material and add 1-30%, preferably 5-20%, of Kanuma soil fine powder. The size of the Kanuma soil is usually fine enough that it cannot be used as Kanuma soil, and is preferably 16 mesh or less.
[0008]
[Action]
Indestructible natural fibers do not rot for a long time, so the sludge drainage is ensured for a long time, the mudability is improved, and it can be reused as landfill for parks and the like. In addition, these natural fibers increase the gas phase rate of sludge, have sterilizing power and insecticidal power, suppress harmful pests in the sludge, and can be reused as planting water and soil.
[0009]
When toxic substances and odors are present in sewage / sludge, the combination of immortal fibers and combustion ash is particularly effective and can effectively fix and remove these harms. Sterilization / algaecidal / insecticidal power is also effective for the purification of sewage, preventing harmful diseases and pests in the sewage and keeping it fibrous without being spoiled is effective as a filter material when used as a filter. For example, A tank having a drain hole in the bottom is covered with immortal natural fibers and combustion ash, and sewage is gradually poured from above, filtered, filtered to prevent odors and sterilized to purify the water. In addition, return the purified water to the original and continuously You may purify the filthy water. Moreover, immortal natural fiber and combustion ash are attached to a thickness of 2 cm as a filter cloth, and sewage is purified by pressurization or decompression.
[0010]
Also, runways in snowy areas where snow melting agents are frequently sprayed, green areas along roads, and green areas and farmlands along coastlines are susceptible to salt damage. In the past, when it was damaged by salt damage, it was necessary to replace the soil. However, according to the present invention, it is not necessary to replace the soil. I can do it.
[0011]
Today, agriculture is also said to be the cause of river pollution. 80-90% of the applied fertilizer and 30-70% of the agricultural chemical are washed away into the river without being used. According to the present invention, this agricultural chemical / fertilizer To prevent the runaway. The mechanism has not been fully elucidated, but it prevents the accumulation of pesticides and fertilizers, accumulation on the surface soil, and sagging due to rainfall. Already planted turf cannot be mixed with turf floor soil, so the material of the present invention is mixed with sand or soil and applied as joint soil. It can also be used as planting soil, spraying material, and soil improvement material. A water wheel is an important tourism resource, and the water can be purified while incorporating the material of the present invention into a water wheel as a tourism resource. Specifically, the recycled material is incorporated into a water turbine having a box on the bottom surface of the side surface formed of a perforated body, and the sewage is purified while turning the water turbine.
