【発明の属する技術分野】
この発明は、河川・湖沼・海等の水質浄化方法に関し、特に、好気性微生物群（好気性バクテリア）の活動（分解能力）を利用することによって、汚染物質を分解して水質を浄化する水質浄化方法に関する。
【０００２】
【従来の技術】
従来の水質浄化方法としては、水底の土砂（汚泥物、ヘドロ等）をさらう浚渫が多く行われている。この浚渫は、浚渫設備が大変であるし、水底からさらったヘドロ等の撤去・運搬に費用もかさむと共に、ヘドロ等の廃棄に関し公害問題もあり、捨て場にも難儀する課題がある。
そこで、最近では微生物を利用した水質浄化方法が提案されている。この水質浄化方法は、水中にれき（石）を積み上げ、このれきの間に水を通し、れきに定着した微生物で汚れを分解・浄化する方法（例えば、特許文献１参照）が多い。
【０００３】
【特許文献１】
特許第２８２２３７１号公報（段落番号０００５及び０００６、図４）
【０００４】
【発明が解決しようとする課題】
しかしながら、従来の微生物を利用した水質浄化方法では、微生物の発生・定着は、れきに自然に定着するのをまたなければならないので浄化作用がはじまるまでに期間が必要となるし、また、れきを用意するのも運搬、費用等を考慮すると大変であるし、さらに、れき（石）の積み上げ作業も大変であり、工期も長くかかる課題がある。
この発明は、このような課題に鑑み提案されたものであり、その目的は、設置が容易で短期間にでき、費用も安価であると共に水質浄化作用の高い水質浄化方法の提供にある。
【０００５】
【課題を解決するための手段】
前記課題を解決するため、この発明の水質浄化方法は、樹脂線状体を絡み合せて中空円柱状に積層して立体空隙構造体を形成し、該立体空隙構造体の複数を水中に、横に寝かせ及び／又は垂直方向に立設して設置すると共に、該水中に設置する一部または全部の立体空隙構造体に好気性微生物群を主成分とする汚染物質浄化剤が収容されていることを特徴とする。
【０００６】
これにより立体空隙構造体は、樹脂線状体を絡み合せて中空円柱状に積層して形成するので安価に容易に製造でき、用意するのも容易であるし、軽量なので運搬および設置も容易である。また、立体空隙構造体は、樹脂線状体を絡み合わせて中空円柱状に積層したものであるので、無数の互いに連通する空隙が存在し、この空隙を介し全外周面および軸線方向に連通し、中空部は軸線方向および空隙を介し全外周面に連通する。この水中に設置した一部または全部の立体空隙構造体には、好気性微生物群を主成分とする汚染物質浄化剤が収容されているので、この汚染物質浄化剤が水中に溶解し、その微生物群は立体空隙構造体、底およびその周辺に定着・増殖する。従って、浄化作用は早期に開始されるし、好気性微生物群は、絡み合っている全ての樹脂線状体の表面に定着・増殖しているので、水との接触面積も広く、かつ、水底およびその周辺に定着・増殖している好気性微生物群と相俟って、効率よく浄化作用が行われる。しかも水底（川底、湖底、海底など）に定着・増殖した好気性微生物群は、水底に堆積した汚泥物やヘドロ等も分解し浄化するので、水質浄化は一層促進される。さらに、ヘドロの処理にも役立つ。
【０００７】
また、この発明の水質浄化方法は、樹脂線状体を絡み合せて中空円柱状に積層して立体空隙構造体を形成し、該立体空隙構造体の複数を水中に、横に寝かせ及び／又は垂直方向に立設して設置し、該水中に設置する一部または全部の立体空隙構造体に好気性微生物群を主成分とする汚染物質浄化剤が収容されると共に、少なくとも水中に設置した立体空隙構造体の近傍に酸素を供給することを特徴とする。
これにより前記作用効果を奏すると共に、この発明では酸素を供給することができるので曝気して水中の汚染ガスを分離して大気に放出して水質浄化が図れると共に、水中での容存酸素量を確保し、微生物群の活動を活発化することができる。
【０００８】
さらに、この発明の水質浄化方法の前記立設して配置した立体空隙構造体には、各立体空隙構造体毎に、下端に重りが固着されていることを特徴とする。
これにより立体空隙構造体を立設するときは、重りで水中に沈下し底に固定でき、他の固定手段が不要となる。特に、各立体空隙構造体毎に重りが設けられているので、垂直方向の立設が容易となり施工性がよい。
【０００９】
【発明の実施の形態】
以下、この発明を図面に示した実施の形態により詳細に説明する。図１はこの発明の第１の実施の形態を示す説明斜視図である。
この図１に示す実施の形態は、好気性微生物群を主成分とする汚染物質浄化剤を収容した立体空隙構造体１の複数を、河川Ｒの水中に設置し、この立体空隙構造体１に収容した汚染物質浄化剤及びこの汚染物質浄化剤により立体空隙構造体１、川底およびその周辺等に定着・繁殖した微生物により汚染物質を分解し水質を浄化する方法にある。
【００１０】
立体空隙構造体１は、樹脂線状体を絡み合せて無数の互に連通する空隙が存在する所定形状に積層して形成したものであり、透水性が高いものである。
図２は立体空隙構造体の実施の形態を示す斜視図、図３は立体空隙構造体の拡大部分斜視図である。この立体空隙構造体１は、同図に示すように樹脂線状体２を絡み合せて中空部３を有する円柱状に積層して形成され、無数の互に連通する空隙が存在し、透水性（通水性）となっている。即ち、立体空隙構造体１は、樹脂線状体２を絡み合わせて中空円柱状に積層したものであるので、無数の互いに連通する空隙が存在し、この空隙を介し全外周面および軸線方向に連通し、中空部３は軸線方向および空隙を介し全外周面に連通する。
【００１１】
汚染物質浄化剤は、好気性微生物群（好気性バクテリア）を主成分とするものであり、汚染物質を分解し無害化するものである。これは粉体などの固形状でも、練状でも、液状でもよい。一例として好気性バクテリアを培養し、粉体としたもので、イーエーイーテック株式会社製の「ＳＵＰＥＲ−Ｋ」（商品名）を例示することができる。
この汚染物質浄化剤は、前記立体空隙構造体１の中空部３に収容する。例えば、粉体の汚染物質浄化剤を透水性の袋に容入し、これを立体空隙構造体１の中空部３に収容する。
【００１２】
立体空隙構造体１の複数は、図１に示すように河川Ｒの水中に設置され、この一部または全部の立体空隙構造体１に前記汚染物質浄化剤が収容される。本例では川底に杭４が打ち込まれ、立体空隙構造体１の複数がまとめられて該杭４に線条体５で固定されて設置され、これが複数群設けられている。この各群には、少なくとも１本の汚染物質浄化剤を収容した立体空隙構造体１が存在するのが好ましい。
この立体空隙構造体１の深さ方向の設置位置としては、水面、中間、底部およびこれらの併用のいずれでもよい。この深さ方向の設置位置あるいは立体空隙構造体１の設置する数、設置群の位置、その間隔等は、河川の幅、水深、底に堆積した汚泥やヘドロの量、その汚染度および水質の汚染度、等を考慮して決定する。
特に、河川、湖沼、海等に排水や支流が流入している場合には、この流入口の近傍に立体空隙構造体１を設置すると、流入する汚染水が拡大する前に浄化できるので好ましい。
なお、汚染物質浄化剤は、水中に設置する立体空隙構造体群の全てに収容しても、その一部に収容してもよく、これは任意である。
【００１３】
しかして、この実施の形態によれば、水中に設置した立体空隙構造体１の一部または全部には、中空部３に汚染物質浄化剤が収容されているので、この汚染物質浄化剤は水中に溶解し、その汚染物質浄化剤の主成分である好気性微生物群は、立体空隙構造体１、川底およびその周辺に定着・増殖する。水中に設置した立体空隙構造体１は、樹脂線状体２を絡み合せて中空部３を有する円柱状に積層して形成されており、無数の互に連通する空隙が存在し、この空隙を介し全外周面および軸線方向に連通し、中空部３は軸線方向および空隙を介し全外周面に連通し、透水性（通水性）であるので、河川Ｒの水は、設置した立体空隙構造体１中を通過して流れることになる。従って、汚染された河川Ｒの水は、溶解した汚染物質浄化剤、および立体空隙構造体１、川底、その周辺に定着・増殖した好気性微生物群に接触し、汚染物質が付着、補足されて分解され浄化される。この時、立体空隙構造体１は、樹脂線状体２を絡み合せて中空部３を有する円柱状に積層してなるので、好気性微生物群は、絡み合っている全ての樹脂線状体の表面に定着・増殖しているので、水との接触面積が広くなり効率的に浄化作用が行われる。
また、川底（湖底、海底も含む）に定着・増殖した好気性微生物群は川底に堆積した汚泥やヘドロも分解し浄化するので、これにより水質も浄化される。
【００１４】
なお、この実施の形態では、河川Ｒの浄化で説明しているが、これは湖沼、湾内等の浄化にも適用可能であり、この発明ではこれらの全てを包含する。
【００１５】
図４はこの発明の第２の実施の形態を示す説明斜視図である。本例は樹脂線状体２を絡み合せて中空部３を有する円柱状に積層した立体空隙構造体１を、水中に横に寝かせて設置したものと、垂直方向に立設して設置したものとを併用した場合であり、他は前記実施の形態と同様である。
【００１６】
図５はこの発明の第３の実施の形態を示す説明斜視図である。本例は樹脂線状体２を絡み合せて中空部３を有する円柱状に積層した立体空隙構造体１を、水中に垂直方向に立設して設置した場合であり、他は前記実施の形態と同様である。同図において符号９は、底に堆積したヘドロを示す。
これら第２の実施の形態および第３の実施の形態においても、前記第１の実施の形態と同様な作用、効果を奏する。
【００１７】
この水中に垂直方向に立設して設置する立体空隙構造体１としては、図６および図７に示すように樹脂線状体２を絡み合せて中空部３を有する円柱状に積層した立体空隙構造体１の下端に重り６を固着したものを使用すると、重り６で水中に沈下し底に固定できるので、他の固定手段が不要となり有効である。図６に示す重り６は円筒状であり、図７に示す重り６は円錐状であるが、この重りの形状は特に限定されない。また、重り６を設ける立体空隙構造体１の形状も、本例のような中空部３を有する円柱状に限定されるものではない。
【００１８】
図８はこの発明の第４の実施の形態を示す説明斜視図である。本例は水中にエアレーター（曝気装置）７を設置し、曝気を併用する点に特徴がある。すなわち、複数の立体空隙構造体１を水中に横に寝かせて設置し、この設置群の適所にエアレーター（曝気装置）７を設けたもので、他は前記実施の形態と同様である。このエアレーター７は、給気装置を内蔵したものでもよいし、図８に示すようにコンプレッサー８を設置し、これから給気するようにしてもよい。
この第４の実施の形態によれば、エアレーター７により曝気したり、水中に給気することができる。従って、前記第１の実施の形態と同様な効果に加えて、曝気により汚染ガスを分離して大気に放出できるし、水中の溶存酸素が不足しても酸素（空気）を供給し、微生物の活動を活発化することができるので、水質浄化の効果は一層向上する。
【００１９】
水中へのエアレーター７の設置位置は任意であるが、設置した立体空隙構造体１群の近傍か、図９に示すような設置した立体空隙構造体１の下方位置が、立体空隙構造体１に収容した汚染物質浄化剤の周辺に酸素を供給でき、微生物の活動を活発化できるので好ましい。また、エアレーター７は、継続的な作動でも、適当な間隔の作動でも、あるいは必要とするときだけの作動でもよく、水質の汚染度に応じて決定すればよい。図９において符号９は、底に堆積したヘドロを示す。
【００２０】
図１０はこの発明の第５の実施の形態を示す説明斜視図である。本例は下端に重り６を有する立体空隙構造体１の複数を水中に垂直方向に立設し、この群立する適所にエアレーター７を設置した場合であり、他は前記実施の形態と同様である。この第５の実施の形態においても、前記第４の実施の形態と同様な効果を奏する。
【００２１】
なお、前記実施の形態は、この発明を制限するものではなく、この発明は要旨を逸脱しない範囲で種々の変形が許容される。例えば、汚染物質浄化剤は、水中に設置した全ての立体空隙構造体１に収容する必要はなく、任意のものでもよい。汚染物質浄化剤を収容しない立体空隙構造体１にも、汚染物質浄化剤を収容した立体空隙構造体１の汚染物質浄化剤が溶解して定着し増殖するからである。また、この発明は水質浄化方法であるが、底に堆積した汚泥やヘドロを分解・浄化し、水質浄化する場合も包含するものである。また、立体空隙構造体１の形状も前記実施の形態に制限されるものではない。例えば、球形、円錐形および立方体等の形状を例示できる。
【００２２】
【発明の効果】
以上詳細に説明した通り、この発明の水質浄化方法によれば次のような効果を奏する。
（１）水中に設置した一部または全部の立体空隙構造体には、好気性微生物群を主成分とする汚染物質浄化剤が収容されているので、この汚染物質浄化剤が水中に溶解し、その微生物群は立体空隙構造体、底およびその周辺に定着・増殖する。従って、浄化作用は早期に開始されるし、好気性微生物群は、絡み合っている全ての樹脂線状体の表面に定着・増殖しているので、水との接触面積も広く、かつ、水底およびその周辺に定着・増殖している好気性微生物群と相俟って、効率よく浄化作用が行われる。しかも水底（川底、湖底、海底など）に定着・増殖した好気性微生物群は、水底に堆積した汚泥物やヘドロ等も分解し浄化するので、水質浄化は一層促進される。さらに、ヘドロの処理にも役立つ。
【００２３】
（２）立体空隙構造体は、樹脂線状体を絡み合せて所定形状に積層して形成するので安価に容易に製造でき、用意するのも容易であるし、軽量なので運搬および設置も容易である。

【００２５】
（４）また、立体空隙構造体が重りを具備すると、重りで水中に沈下し底に固定できるので、他の固定手段が不要となる。

[0004]
[Problems to be solved by the invention]
However, in the conventional water purification method using microorganisms, the generation and establishment of microorganisms must continue to settle naturally in the rubble, so a period of time is required until the purification action begins. It is difficult to prepare in consideration of transportation, cost, etc. In addition, the work of stacking rubble (stone) is also difficult, and there is a problem that takes a long construction period.
The present invention has been proposed in view of such problems, and an object thereof is to provide a water purification method that is easy to install, can be made in a short period of time, is inexpensive, and has a high water purification effect.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the water purification method of the present invention is a method of forming a three-dimensional void structure by intertwining resin linear bodies and laminating them in a hollow cylindrical shape , and placing a plurality of the three-dimensional void structures in the water . aged and / or while placed upright in the vertical direction, contaminant cleaning agent composed mainly some or all of the three-dimensional gap structure aerobic microorganisms to be installed in the water is accommodated that the It is characterized by.

In addition, since the three-dimensional void structure is formed by entangled resin linear bodies and laminated in a hollow cylindrical shape, there are innumerable voids communicating with each other, and these voids communicate with each other in the entire outer circumferential surface and the axial direction. The hollow portion communicates with the entire outer peripheral surface through the axial direction and the gap. Since some or all of the three-dimensional void structures installed in the water contain a pollutant cleaning agent mainly composed of aerobic microorganisms, the pollutant cleaning agent dissolves in the water and the microorganism The group settles and grows in the three-dimensional void structure, the bottom and the periphery. Therefore, the purification action is started early, and the aerobic microorganism group is fixed and proliferated on the surface of all the entangled resin linear bodies, so that the contact area with water is wide, and the bottom of the water and Combined with the aerobic microorganism group that has settled and proliferated in the vicinity, the purification action is performed efficiently. Moreover, the aerobic microorganism group that has settled and propagated on the bottom of the water (river bottom, lake bottom, sea bottom, etc.) decomposes and purifies sludge and sludge accumulated on the bottom of the water, thereby further promoting water quality purification. It is also useful for sludge treatment.
[0007]
In the water purification method of the present invention, a resin linear body is entangled and laminated into a hollow cylindrical shape to form a three-dimensional void structure, and a plurality of the three-dimensional void structures are laid sideways in water and / or A part or all of the three-dimensional void structure installed in the vertical direction contains a contaminant purifier containing aerobic microorganisms as a main component, and at least a three-dimensional object installed in water. Oxygen is supplied in the vicinity of the void structure.

In particular, since a weight is provided for each three-dimensional void structure, it is easy to stand in the vertical direction and the workability is good.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. FIG. 1 is an explanatory perspective view showing a first embodiment of the present invention.
In the embodiment shown in FIG. 1, a plurality of three-dimensional void structures 1 containing a pollutant purifying agent mainly composed of aerobic microorganisms are installed in the water of a river R. There is a method of decomposing pollutants and purifying the water quality by the contained pollutant purifier and microorganisms that have settled and propagated in the three-dimensional void structure 1, the riverbed and its surroundings, etc. with this pollutant purifier.
[0010]
The three-dimensional void structure 1 is formed by entwining resin linear bodies and laminating them into a predetermined shape having innumerable voids communicating with each other, and has high water permeability.
FIG. 2 is a perspective view showing an embodiment of a three-dimensional void structure, and FIG. 3 is an enlarged partial perspective view of the three-dimensional void structure. This three-dimensional void structure 1 is formed by intertwining resin linear bodies 2 and forming a cylindrical shape having a hollow portion 3 as shown in the figure, and there are innumerable voids communicating with each other. (Water permeability). That is, since the three-dimensional void structure 1 is formed by entangled the resin linear bodies 2 and laminated in a hollow cylindrical shape, there are innumerable voids communicating with each other, and the entire outer circumferential surface and the axial direction are interposed through the voids. The hollow portion 3 communicates with the entire outer peripheral surface through the axial direction and the gap.
[0011]
The pollutant cleaning agent is mainly composed of aerobic microorganisms (aerobic bacteria), and decomposes and detoxifies the pollutants. This may be solid such as powder, kneaded or liquid. As an example, an aerobic bacterium is cultured to form a powder, and “SUPER-K” (trade name) manufactured by AE Tech Co., Ltd. can be exemplified.
This contaminant purifying agent is accommodated in the hollow portion 3 of the three-dimensional void structure 1. For example, a powder contaminant purifier is placed in a water-permeable bag and accommodated in the hollow portion 3 of the three-dimensional void structure 1.
[0012]
A plurality of the three-dimensional void structures 1 are installed in the water of the river R as shown in FIG. 1, and the contaminant purifying agent is accommodated in a part or all of the three-dimensional void structures 1. In this example, piles 4 are driven into the riverbed, and a plurality of three-dimensional void structures 1 are gathered together and fixed to the piles 4 with the filaments 5, and a plurality of groups are provided. Each group preferably has a three-dimensional void structure 1 containing at least one contaminant purifier.
The installation position in the depth direction of the three-dimensional void structure 1 may be any of the water surface, the middle, the bottom, and a combination thereof. The installation position in the depth direction or the number of installations of the three-dimensional void structure 1, the positions of the installation groups, and the distance between them are the width of the river, the water depth, the amount of sludge and sludge deposited on the bottom, the degree of contamination, Determined by considering the degree of contamination.
In particular, when drainage or tributaries flow into rivers, lakes, seas, etc., it is preferable to install the three-dimensional void structure 1 in the vicinity of this inflow port because the contaminated water that flows in can be purified before it expands.
In addition, the pollutant purification agent may be accommodated in all or part of the three-dimensional void structure group installed in water, and this is optional.
[0013]
Therefore, according to this embodiment, a part or all of the three-dimensional void structure 1 installed in the water contains the contaminant purifier in the hollow portion 3, so that the contaminant purifier is submerged in the water. The aerobic microorganism group which dissolves in the water and is the main component of the pollutant purifier settles and proliferates in the three-dimensional void structure 1, the riverbed and the vicinity thereof. Steric void structure 1 placed in the water is entangled resin linear member 2 is formed by laminating into a cylindrical shape having a hollow portion 3, there are gaps in communication myriad each other, the gap Since the hollow portion 3 communicates with the entire outer peripheral surface through the axial direction and the gap and is permeable (water permeable), the water of the river R is installed in the three-dimensional void structure. It will flow through 1. Therefore, the contaminated water in the river R comes into contact with the dissolved pollutant purifier and the three-dimensional void structure 1, the bottom of the river, and the aerobic microorganisms that have settled and proliferated in the vicinity, and the pollutants are attached and supplemented. Disassembled and purified. At this time, the three-dimensional void structure 1 is formed by stacking the resin linear bodies 2 in a cylindrical shape having the hollow portions 3, so that the aerobic microorganism group is the surface of all the intertwined resin linear bodies. Since it settles and proliferates, the contact area with water is widened and the purification action is performed efficiently.
In addition, aerobic microorganisms colonized and proliferated on the riverbed (including lake and seabeds) also decompose and purify sludge and sludge deposited on the riverbed, thereby purifying the water quality.
[0014]
In this embodiment, the purification of the river R has been described, but this can also be applied to purification of lakes, bays, etc., and the present invention includes all of these.
[0015]
FIG. 4 is an explanatory perspective view showing a second embodiment of the present invention. In this example, the three-dimensional void structure 1 in which resin linear bodies 2 are entangled and stacked in a columnar shape having a hollow portion 3 is laid sideways in water, and is installed in a vertical direction. Are the same as in the above embodiment.
[0016]
FIG. 5 is an explanatory perspective view showing a third embodiment of the present invention. This example is a case where the three-dimensional void structure 1 in which resin linear bodies 2 are entangled and stacked in a columnar shape having a hollow portion 3 is installed in a vertical direction in water. It is the same. In the figure, reference numeral 9 indicates sludge deposited on the bottom.
In the second embodiment and the third embodiment, the same operations and effects as the first embodiment are achieved.
[0017]
As the three-dimensional void structure 1 that is erected in the vertical direction in the water, as shown in FIGS. 6 and 7, the three-dimensional voids in which resin linear bodies 2 are entangled and stacked in a cylindrical shape having a hollow portion 3. If the weight 1 is fixed to the lower end of the structure 1, the weight 6 can be submerged in the water and fixed to the bottom, so that other fixing means are unnecessary and effective. The weight 6 shown in FIG. 6 is cylindrical, and the weight 6 shown in FIG. 7 is conical, but the shape of this weight is not particularly limited. Further, the shape of the three-dimensional void structure 1 provided with the weight 6 is not limited to the columnar shape having the hollow portion 3 as in this example.
[0018]
FIG. 8 is an explanatory perspective view showing a fourth embodiment of the present invention. This example is characterized in that an aerator (aeration device) 7 is installed in water and aeration is used in combination. In other words, a plurality of three-dimensional void structures 1 are placed in the water and laid sideways, and an aerator (aeration device) 7 is provided at an appropriate position in this installation group, and the others are the same as in the above embodiment. The aerator 7 may include a built-in air supply device, or may be provided with a compressor 8 as shown in FIG.
According to the fourth embodiment, aeration can be performed by the aerator 7 or air can be supplied to the water. Therefore, in addition to the same effect as the first embodiment, the pollutant gas can be separated and released into the atmosphere by aeration, and oxygen (air) can be supplied even if the dissolved oxygen in the water is insufficient. Since activities can be activated, the effect of water purification is further improved.
[0019]
Although the installation position of the aerator 7 in water is arbitrary, the lower position of the installed three-dimensional void structure 1 as shown in FIG. It is preferable because oxygen can be supplied to the vicinity of the pollutant cleaning agent contained in the container and the activity of microorganisms can be activated. The aerator 7 may be operated continuously, at an appropriate interval, or only when necessary, and may be determined in accordance with the degree of water quality contamination. In FIG. 9, the code | symbol 9 shows the sludge deposited on the bottom.
[0020]
FIG. 10 is an explanatory perspective view showing a fifth embodiment of the present invention. In this example, a plurality of three-dimensional void structures 1 each having a weight 6 at the lower end are vertically installed in water, and an aerator 7 is installed at an appropriate place to be clustered. It is. In the fifth embodiment, the same effects as in the fourth embodiment are obtained.
[0021]
The above embodiment does not limit the present invention, and various modifications are allowed without departing from the spirit of the present invention. For example, the pollutant purifying agent need not be accommodated in all the three-dimensional void structures 1 installed in water, and may be arbitrary. This is because the contaminant purifying agent of the three-dimensional void structure 1 containing the contaminant purifying agent dissolves, settles, and proliferates also in the three-dimensional void structure 1 that does not contain the contaminant purifying agent. Moreover, although this invention is a water quality purification method, it also includes the case where the sludge and sludge deposited on the bottom are decomposed and purified to purify the water. Further, the shape of the three-dimensional void structure 1 is not limited to the above embodiment. For example, shapes such as a sphere, a cone, and a cube can be exemplified.
[0022]
【The invention's effect】
As described in detail above, the water purification method of the present invention has the following effects.
(1) Since some or all of the three-dimensional void structures installed in water contain a pollutant cleaning agent mainly composed of aerobic microorganisms, the pollutant cleaning agent dissolves in water, The microorganism group settles and grows on the three-dimensional void structure, the bottom and the periphery thereof. Therefore, the purification action is started early, and the aerobic microorganism group is fixed and proliferated on the surface of all the entangled resin linear bodies, so that the contact area with water is wide, and the bottom of the water and Combined with the aerobic microorganism group that has settled and proliferated in the vicinity, the purification action is performed efficiently. Moreover, the aerobic microorganism group that has settled and propagated on the bottom of the water (river bottom, lake bottom, sea bottom, etc.) decomposes and purifies sludge and sludge accumulated on the bottom of the water, thereby further promoting water quality purification. It is also useful for sludge treatment.
[0023]
(2) The three-dimensional void structure is formed by intertwining resin linear bodies and laminating them into a predetermined shape, so that it can be easily manufactured at low cost, is easy to prepare, and is light and easy to transport and install. is there.
[0024]
(3) In the present invention, oxygen can be supplied and aerated, or the amount of dissolved oxygen can be secured. Therefore, the polluted gas in the water can be aerated and released into the atmosphere to purify the water, and the water can be purified. The amount of oxygen can be secured and the activity of the microorganism group can be activated. Therefore, efficient purification can be achieved by a synergistic effect with the activities of the microorganism group.
[0025]
(4) If the three-dimensional void structure is provided with a weight, it can sink into the water and be fixed to the bottom with the weight, so that no other fixing means is required.
