Landfill tank 1 for introducing waste, input device 2 for introducing waste into landfill tank 1, oxygen enrichment apparatus 3 for taking out the water supplied to landfill tank 1 and enriching it with oxygen, and water enriched with oxygen Is constituted again with a water supply device 4 for supplying to the landfill tank 1.

＜１−１＞埋立槽１。
埋立槽１は周囲の壁をコンクリート製の板体で構成し、底板を設け、上部は開放した箱状体で構成した構造体が一般的である。
埋立槽１は一般に地中に設置するが、地上、半地下状態に設置することも可能である。 <1-1> Landfill tank 1.
The landfill tank 1 is generally a structure in which the surrounding wall is made of a plate made of concrete, a bottom plate is provided, and the upper part is made of an open box.

一方、埋立槽１の底部には、排水用の集排水管４２を敷設して、この集配水管４２で集水した水を集水ピット４３に集め酸素富化水製造装置３を通して循環させる。
ただし水の供給位置、排水位置は、埋立槽１の上下に限定されるものではなく、下方から水を供給し、上方から排水する構造、あるいは両者を混在させた構造などを採用することができる。
酸素富化水の循環は必ずしもポンプを使用せず、地形によっては自然流下させて酸素富化装置３を通して循環させる方法を採用することができる。 <1-2> Water supply and drainage system.
The water supply device 4 is a device that supplies the oxygen-enriched water produced in the oxygen-enriched water production 3 described later into the landfill tank 1 through the water supply pipe 41.
On the other hand, a drainage drainage pipe 42 is laid at the bottom of the landfill tank 1, and the water collected by the drainage pipe 42 is collected in the water collection pit 43 and circulated through the oxygen-enriched water production apparatus 3.
However, the water supply position and the drainage position are not limited to the top and bottom of the landfill tank 1, and a structure in which water is supplied from below and drained from above, or a structure in which both are mixed can be employed. .
Circulation of oxygen-enriched water does not necessarily use a pump, and depending on the terrain, it is possible to adopt a method in which the oxygen-enriched water is circulated through the oxygen-enriching device 3 by flowing down naturally.

＜１−３＞投入装置２。
廃棄物を埋立槽１に投入する投入装置２は、ホッパーやベルコンなどが一般的である。
しかしダンプトラックやショベルカーから直接、埋立槽１内へ廃棄物を投入する場合にはそのトラックやショベルカーを投入装置２とみなすことができる。
ダンプカーなどが埋立槽１の上部空間へ移動できるようにステージを組み立てる構成を採用することができる。
なお、この実施例は埋立槽１が単数の場合であるが、後述するような埋立槽１が複数の構造では、図３に示すように埋め立て対象の埋立槽１だけにステージ１２を組み立てる構成、あらかじめすべての埋立槽１にステージ１２を設置しておく構成、あるいはステージ１２を上下に分けて、下部だけを各埋立槽１に設置しておき、上部をそのつど投入する埋立槽１に付け替えて転用する構成を採用することもできる。
またラダー方式の投入装置２や、天井クレーンのような公知の装置を使用することもできる。 <1-3> Input device 2.
As the charging device 2 for charging the waste into the landfill tank 1, a hopper, a velcon or the like is generally used.
However, when throwing waste into the landfill tank 1 directly from the dump truck or shovel car, the truck or shovel car can be regarded as the loading device 2.
The structure which assembles a stage so that a dump truck etc. can move to the upper space of the landfill tank 1 is employable.
In addition, although this Example is a case where the number of the landfill tank 1 is single, when the landfill tank 1 as described later has a plurality of structures, a configuration in which the stage 12 is assembled only in the landfill tank 1 to be landfilled as shown in FIG. A configuration in which the stages 12 are installed in advance in all landfill tanks 1 or the stage 12 is divided into upper and lower parts, only the lower part is installed in each landfill tank 1, and the upper part is replaced with the landfill tank 1 to be charged each time. A diverted configuration can also be employed.
Also, a ladder-type charging device 2 or a known device such as an overhead crane can be used.

＜１−４＞酸素富化装置３。
酸素富化装置３は、埋立槽１から引き出した水に酸素を供給して酸素富化水を製造する装置であり、例えば酸素富化膜などを使用して作成した酸素濃度の高い空気を曝気して酸素富化水を作るような構成である。
あるいは、図３の実施例のように、酸素ボンベから高濃度の酸素と水道水をばっき装置３１へ供給して曝気する装置、マイクロバブルやノナバブル発生装置などを使用して酸素富化水を製造する公知の装置、方法などを採用することができる。 <1-4> Oxygen enrichment device 3.
The oxygen enrichment apparatus 3 is an apparatus that supplies oxygen to the water drawn from the landfill tank 1 to produce oxygen enriched water. For example, the oxygen enrichment apparatus 3 aerated high oxygen concentration air created using an oxygen enriched film or the like. Thus, it is configured to make oxygen-enriched water.
Alternatively, as in the embodiment of FIG. 3, oxygen-enriched water is supplied using a device that supplies aeration by supplying high-concentration oxygen and tap water from an oxygen cylinder to the flash device 31, a microbubble or a nona bubble generator, and the like. Known apparatuses and methods for manufacturing can be employed.

＜１−５＞水量の制御。
埋立槽１から引き出した水は、埋め立ての量だけ増加して上昇し、蒸発分だけ減少して下降するから、その差の量を外部へ排出して埋立槽１内の水位を一定に保つように制御する。
つまり、廃棄物の投入により水位が上昇しそうな場合には水位調整バルブ６１の操作によって、その量に比例した分だけ水処理装置６へ送り、処理をした後に外部へ排水する。
水位調整バルブ６１は、埋立槽１から引き出した水を酸素富化製造装置３か、あるいは水処理装置６に送水する切り替えの弁である。
一方、水位が下降しそうな場合にはその量に比例した分だけ外部から水道水などを導入することによって水位を一定に保つことが必要である。 <1-5> Control of the amount of water.
The water drawn from the landfill tank 1 increases by the amount of landfill, rises, decreases by the amount of evaporation, and falls, so that the amount of the difference is discharged to the outside so as to keep the water level in the landfill tank 1 constant. To control.
That is, when the water level is likely to rise due to the input of waste, the water level adjusting valve 61 is operated to send it to the water treatment device 6 by an amount proportional to the amount, and after processing, the water is discharged to the outside.
The water level adjustment valve 61 is a switching valve for supplying water drawn from the landfill tank 1 to the oxygen enrichment production apparatus 3 or the water treatment apparatus 6.
On the other hand, when the water level is likely to fall, it is necessary to keep the water level constant by introducing tap water or the like from the outside in proportion to the amount.

＜１−６＞屋根。
埋立槽１の上部には埋立槽１を覆う移動式、あるいは固定式の屋根５を設けて、降雨による水量の変化を阻止する。 <1-6> Roof.
A movable or fixed roof 5 that covers the landfill tank 1 is provided above the landfill tank 1 to prevent a change in the amount of water due to rain.

＜２＞他の実施例（図２、３）（複数の埋立槽の場合）。
上記の実施例は埋立槽１が単数の構成であったが、廃棄物を投入する埋立槽１を複数の埋立槽１として構成することもできる。
複数の埋立槽１は、周囲の外壁の内部を仕切壁１１で区切って構成したものである。
仕切壁１１としてはコンクリート製の壁が一般的であるが、その他の利用できる公知の材料、形式、方法を採用することができ、例えば補強盛土工法を適用することもできる。
すなわち補強盛土を積み上げた壁を仕切壁１１として採用するような構造である。
複数の埋立槽１を平面的に一列に並べる構成、「田」の字型に配置する構成（図４）など自由な組み合わせを採用することができる。
その他の、給水装置４、投入装置２、酸素富化水製造装置３などの構成は上記の実施例と同様である。 <2> Other examples (FIGS. 2 and 3) (in the case of a plurality of landfill tanks).
In the above-described embodiment, the landfill tank 1 has a single configuration, but the landfill tanks 1 into which the waste is introduced can be configured as a plurality of landfill tanks 1.
The plurality of landfill tanks 1 are configured by dividing the inside of the surrounding outer wall by a partition wall 11.
Although the concrete wall is generally used as the partition wall 11, other known materials, types, and methods that can be used can be employed. For example, a reinforced embankment method can also be applied.
That is, it is a structure which employ | adopts the wall which piled up the reinforcement embankment as the partition wall 11. FIG.
A free combination such as a configuration in which a plurality of landfill tanks 1 are arranged in a row in a plane, or a configuration in which a plurality of landfill tanks 1 are arranged in a “rice” shape (FIG. 4) can be employed.
Other configurations of the water supply device 4, the charging device 2, the oxygen-enriched water production device 3 and the like are the same as those in the above embodiment.

＜３＞処分方法１（埋立槽１が単槽の場合）
埋立槽１が単数の場合の廃棄物の処分方法について説明する。
上記の埋立槽１が単数の構成の廃棄物処分場を使用し、水の充填してある埋立槽１内に投入装置２によって廃棄物を投入する。
すなわち水中投棄を行う。
水中に廃棄物をそのまま投入すると、前記で指摘したように、水中に溶存している酸素は廃棄物の微生物分解ですぐに消費されてしまい、嫌気性になって水質が悪化する問題がある。
そのような廃棄物の嫌気性分解の阻止と、有機物の早期安定化を図るために、埋立槽１内の水は酸素富化水を採用する。
そのために埋立槽１内の水を例えば底部に配置した集排水管４２から引き出し、酸素富化水製造装置３へ供給する。
そこで酸素富化した水は給水装置４によって埋立槽１内へ循環して供給し、埋立槽１内が嫌気状態にならないように維持する。
その際に、廃棄物の投入によって生じた余剰水は水処理装置６において一定の水処理を行って外部へ排水する。
埋立槽１内へ投入した廃棄物が水面から露出するようになったら投入を終了する。
その後、底部に配置した集排水管４２から内部の水を排水して、通常の準好気状態に戻し、上部には最終覆土を行い、あるいはキャッピングシートで覆い、雨水の影響を排除する。
埋立槽１の内部の水を排水することによって廃棄物を締め固めるという効果も期待できる。
埋立槽１内の水は、廃棄物の投棄の進行と平行して、すなわち埋立槽１内の酸素消費量にあわせて徐々に酸素富化水に置き換えても、あるいは埋立槽１内の水を酸素富化水に置き換えてから廃棄物の投入を行うことができる。
廃棄物の投入の終了後に表面を被覆したシートの下には散水管を配置して散水を施す場合もある。
その際に有機物の安定化がさらに必要である場合には、酸素富化水の散水を継続する。
有機物以外の物質の安定化が必要である場合には、対象とする非安定化物質を早期に安定化させるための薬剤などを散布する。
このような作業によって、埋め戻し後に散水施設やシートを速やかに撤去することが可能であり、迅速に埋立後の跡地の転用を図ることができる。 <3> Disposal method 1 (when landfill tank 1 is a single tank)
A method for disposing of waste when there is a single landfill tank 1 will be described.
The landfill tank 1 uses a waste disposal site having a single structure, and the throwing device 2 puts waste into the landfill tank 1 filled with water.
That is, dumping in water.
When waste is put into water as it is, as pointed out above, oxygen dissolved in water is consumed immediately by microbial decomposition of the waste, resulting in anaerobic and water quality deterioration.
In order to prevent such anaerobic decomposition of waste and to stabilize organic matter at an early stage, oxygen-enriched water is used as the water in the landfill tank 1.
For this purpose, the water in the landfill tank 1 is drawn from, for example, a collecting / draining pipe 42 arranged at the bottom and supplied to the oxygen-enriched water production apparatus 3.
Therefore, the oxygen-enriched water is circulated and supplied into the landfill tank 1 by the water supply device 4 and is maintained so that the inside of the landfill tank 1 does not become anaerobic.
At that time, surplus water generated by the input of the waste is subjected to a certain water treatment in the water treatment device 6 and discharged to the outside.
When the waste thrown into the landfill tank 1 is exposed from the water surface, the charging is finished.
Thereafter, the internal water is drained from the drainage pipe 42 disposed at the bottom to return to a normal semi-aerobic state, and the top is covered with a final soil or covered with a capping sheet to eliminate the influence of rainwater.
The effect of compacting the waste by draining the water inside the landfill tank 1 can also be expected.
The water in the landfill tank 1 may be replaced with oxygen-enriched water in parallel with the progress of the dumping of the waste, that is, according to the oxygen consumption in the landfill tank 1, or the water in the landfill tank 1 may be replaced. Waste can be input after replacing with oxygen-enriched water.
In some cases, water spraying may be performed by placing a sprinkler tube under the sheet whose surface is covered after the end of the introduction of the waste.
At that time, if further stabilization of the organic matter is necessary, watering of the oxygen-enriched water is continued.
When it is necessary to stabilize substances other than organic substances, a drug for stabilizing the target non-stabilized substance at an early stage is sprayed.
By such an operation, it is possible to quickly remove the watering facility and the sheet after the backfilling, and it is possible to quickly divert the site after the landfill.

＜４＞処分方法２（埋立槽が複数槽の場合）。
埋立槽１が複数の場合の廃棄物の処分方法について説明する。
ひとつの埋立槽１内に投入装置２によって廃棄物を投入し、その埋立槽１内の水を循環して酸素富化状態を維持する点は上記の実施例と同様である。
その場合に、投入を行っていないすべての埋立槽１内には水を充填しておく。
この水の充填によって仕切壁には一面から廃棄物による圧力が、他面からは水による水圧が作用する。
そのために仕切壁１１の厚さはきわめて薄いものとして構成することができる。
埋立槽１内へ投入した廃棄物が水面から露出するようになったらバックホウなどの重機を使って搬入車両が通れるように整地、転圧する。
そして次に埋め立て予定の埋立槽１の内部の水を酸素富化水に置き換え、廃棄物の投入と酸素富化水の循環という同様の作業を行う。
作業中の埋立槽１の上部には屋根５を移動して雨水の影響を遮断する。
こうして順次、投入する埋立槽１を奥の方へ移してゆき、複数の埋立槽１全体の埋め立てを完了する。 <4> Disposal method 2 (when there are multiple landfill tanks).
A method for disposing of waste when there are a plurality of landfill tanks 1 will be described.
The point that waste is thrown into one landfill tank 1 by the charging device 2 and the water in the landfill tank 1 is circulated to maintain the oxygen-enriched state is the same as in the above embodiment.
In that case, all the landfill tanks 1 that have not been charged are filled with water.
Due to this filling of water, pressure from waste is applied to the partition wall from one side and water pressure from the other side.
Therefore, the partition wall 11 can be configured to be extremely thin.
When the waste thrown into the landfill tank 1 is exposed from the surface of the water, the ground leveling and rolling are performed so that the incoming vehicle can pass through using a heavy machine such as a backhoe.
Then, the water inside the landfill tank 1 scheduled to be landfilled is replaced with oxygen-enriched water, and the same operation of charging waste and circulating the oxygen-enriched water is performed.
The roof 5 is moved to the upper part of the landfill tank 1 during work to block the influence of rainwater.
In this way, the landfill tanks 1 to be introduced are sequentially moved to the back, and the landfill of the entire plurality of landfill tanks 1 is completed.

＜５＞処分方法３（酸素濃度を下げる処分方法）。
埋立槽１が単数であっても、複数であってもよいが、上記のような工程で廃棄物の処分がいったん終了したら、その後に定期的に、あるいは随時に、埋立槽１内の水の酸素濃度を下げる。
水の酸素濃度を下げるためには、水の循環を止める方法を採用できる。
あるいは、循環水への酸素供給を止める方法を採用することができる。
この方法では槽内の微生物が槽内の酸素を消費し、嫌気性となるので、その状態で槽内にアルコールなどの有機物を供給して廃棄物の脱窒を行うことができる。 <5> Disposal method 3 (disposal method for reducing the oxygen concentration).
Although the landfill tank 1 may be singular or plural, once the disposal of the waste is completed in the above-described process, the water in the landfill tank 1 is periodically or occasionally thereafter. Reduce oxygen concentration.
In order to reduce the oxygen concentration of water, a method of stopping water circulation can be employed.
Or the method of stopping the oxygen supply to circulating water is employable.
In this method, since microorganisms in the tank consume oxygen in the tank and become anaerobic, in this state, organic matter such as alcohol can be supplied into the tank to denitrify waste.

＜６＞処分方法４（安定化促進剤を混入する処分方法）。
埋立槽１が単数であっても、複数であってもよいが、埋立槽１内の水を循環して酸素富化状態を維持する場合に、さらにこの循環水に安定化促進剤を混合する。
安定化促進剤としては、オゾン水、過酸化水素水、キレート剤水溶液、ランタン水溶液、などを使用できる。
それらの安定化促進剤のうちで、オゾン水と過酸化水素水は、特にＣＯＤやＢＯＤの低減に効果がある。
またキレート剤水溶液は、特に重金属の不溶化に効果がある。
またランタン水溶液は、特にホウ素の低減に効果がある。
その他の工程は上記の実施例と同様である。
<6> Disposal method 4 (disposal method in which a stabilizing accelerator is mixed).
A single landfill tank 1 or a plurality of landfill tanks 1 may be used. However, when the water in the landfill tank 1 is circulated to maintain an oxygen-enriched state, a stabilization promoter is further mixed into the circulating water. .
As the stabilization promoter, ozone water, hydrogen peroxide solution, chelating agent aqueous solution, lanthanum aqueous solution, or the like can be used.
Of these stabilization promoters, ozone water and hydrogen peroxide water are particularly effective in reducing COD and BOD.
The aqueous chelating agent solution is particularly effective for insolubilizing heavy metals.
A lanthanum aqueous solution is particularly effective in reducing boron.
Other steps are the same as those in the above embodiment.
