が軽いので中心部に集まり、泡沫スカムＡは互いに付着
して塊つとなり、浮力によって泡沫スカムＡの塊りは上
部へと浮上する。(d) Due to the centrifugal separation effect in this circular motion, the liquid has a heavy specific gravity, so it gathers outward in the radial direction, and the foamy scum A, which has a low specific gravity, gathers in the center, and the foamy scum A adheres to each other and forms a clump, and due to buoyancy, A mass of foamy scum A floats to the top.

されるが、次の問題点があった。Problems to be Solved by the Present Invention> As described above, by using the flotation separation cyclone device @1 of Japanese Patent Application No. 57-127235, rapid treatment of a large amount of wastewater can be realized, but there are the following problems. Ta.
（ａ）前記浮上分離サイクロン装置１では、原水に泡沫

、泡沫の発生力が弱い（これは原水中の汚濁″ｐＩＪ￥
ｉ、が大きく重量が大であると、泡沫に付着しても、す
ぐ泡沫が壊れてしまうためである。）。(a) In the flotation separation cyclone device 1, foamy scum is generated in the raw water and introduced into the cyclone body 2 of the flotation separation cyclone device 1, but if the raw water is heavily contaminated, the foam generation power is weak ( This is pollution in raw water"pIJ￥
This is because if i is large and the weight is large, even if it adheres to the foam, the foam will break immediately. ).
従って、原水の汚れがひどいほど、泡沫スカムの発生量
が逆に少なくなり、このため、汚濁物資が充分に分離さ
れず、浄化の効率が悪かった。このため、汚れのひどい
原水の場合、浮上分離サイクロン装置１を数段以上設け
なければならなかった。Therefore, the more contaminated the raw water is, the less foamy scum is generated, and therefore, the pollutants are not sufficiently separated, resulting in poor purification efficiency. For this reason, in the case of heavily contaminated raw water, it is necessary to provide several stages or more of flotation separation cyclone devices 1.
（ｂ）らせんバイブロ内で原水中の汚濁物質は泡沫に付
着して泡沫スカムとなって、サイクロン本体２内へ導入

サイクロン本体２内で泡沫（二出会わずにそのまま沈降
してしまうので、浄化の効率が悪かった。(b) In the spiral vibro, the pollutants in the raw water adhere to foam and become foam scum, which is introduced into the cyclone body 2. However, inside the cyclone body 2, the foam continues from the tip 6a of the spiral vibro to the upper part. Therefore, the pollutants that did not adhere to the foam in the spiral vibro were deposited as they were in the cyclone body 2 without meeting the foam, resulting in poor purification efficiency.
（Ｃ）原水中には、各種薬剤による金属のマスキング化

If the raw water is heavily contaminated, odor-emitting substances and B
There are cases where a large amount of OD sources and COD sources are dissolved, and it is inconvenient to directly dispose of them as they are. For this reason, in the past, it was necessary to additionally provide an aeration device or a biological treatment device for treatment, which increased the size of the entire purification device and required land area for these devices.

いる。Means for Solving the Problems 1-1 In order to solve the problem of heat, the flotation separation cyclone device of the present invention takes out part of the liquid from which the foamy scum has been separated from the lower part of the cyclone body and adds it to the liquid. It is characterized by mixing and stirring the gas and circulating it inside the cyclone body.
〈作用〉
このようにしたために、サイクロン本体の下部からは、
泡沫スカムと分離されて浄化された液体の一部が取り出

生した液体がサイクロン本体内に環流される。<Function> Because of this arrangement, from the bottom of the cyclone body,
A portion of the clarified liquid is removed from the foam scum. Even if this purified liquid is heavily contaminated with the raw water initially introduced, it is less contaminated than when it was initially introduced into the cyclone body, so when the gas is mixed and stirred, a large amount of foam is generated. Occur. The liquid in which a large amount of foam has been generated is circulated into the cyclone body.
この環流した液体中の多量の泡沫は、サイクロン本体内
で、初めにサイクロン本体内に円周方向に導入された泡
沫スカムを上方へ浮力によって押し十ける働きをｊ−る

濁物質が、この環流された液体中の多量の泡沫に付着し
て、新らたに多量の泡沫スカムとなって、円周方向に回
遊して中央に集まって泡沫スカムの塊つとなって上昇す
る。A large amount of foam in the refluxed liquid serves to push away the foam scum, which was initially introduced circumferentially into the cyclone body, upwardly within the cyclone body by buoyancy. Not only that, the fine pollutants that are floating or trying to settle downward (without adhering to the foam introduced in the first place) adhere to the large amount of foam in this refluxed liquid and create new A large amount of foamy scum flows around in the circumferential direction, gathers in the center, and rises as a mass of foamy scum.
このため、サイクロン本体内に初めに円周方向に導入さ
れる液体の汚れがひどくて泡沫スカムの発生量が少なく
ても、サイクロン本体の下部から浄化水の一部を取り出
して、気体を混合撹拌して多量の泡沫を含んだ液体とし
て環流させ続けるので、初めに導入された泡沫に付着す
る機会を得すに浄化水中に残存した汚濁物質は順次、泡
沫に付着して除去されることになり、浄化の効率は飛躍
的に向上する。Therefore, even if the liquid initially introduced in the circumferential direction into the cyclone body is heavily contaminated and the amount of foam scum generated is small, a portion of the purified water is taken out from the bottom of the cyclone body and the gas is mixed and stirred. Since the purified water continues to be refluxed as a liquid containing a large amount of foam, the pollutants remaining in the purified water will gradually adhere to the foam and be removed once they have a chance to adhere to the foam that was first introduced. , purification efficiency is dramatically improved.
しかも、環流液体による泡沫は、液体中に残存する試薬
と相俟って１１強固な泡沫スカムとなり、サイクロン本
体から廃棄される浄化水は、−・段と浄化が進む。Moreover, the foam generated by the refluxing liquid, together with the reagent remaining in the liquid, becomes a solid foamy scum, and the purified water discarded from the cyclone body is further purified.
また、サイクロン本体の下部からの液体の環流において
、注入空気と激しく撹拌、混合され、気泡の微細粒子か
ら成る泡沫が多量発生し、処理水と空気との接触が充分
に行なわれるため、浄化水の嘔気作用も充分に行なわれ
る。In addition, during the reflux of liquid from the lower part of the cyclone body, it is vigorously stirred and mixed with the injected air, generating a large amount of foam consisting of fine air bubbles, and the treated water and air are in sufficient contact with each other. The nausea effect is also sufficiently carried out.

どい場合でも、浄化の効率は劣下しない。Effects of the Present Invention> As explained above, in the flotation separation cyclone device of the present invention, a part of the purified water in the cyclone body 12 is taken out from the circulation vibrator 17, and stirred and mixed with air again to generate foam. (a) Since the raw water is heavily contaminated, the cyclone body 12 is
Even if the amount of foamy scum generated from the liquid in the spiral vibrator 116 introduced into the cyclone is small, a portion of the purified water in the cyclone body 12 is taken out into the circulation vibrator 17 and mixed with air, so that the raw water is not severely contaminated. generates a large amount of foam,
Since contaminants in the liquid adhere to this large amount of foam from the circulation vibrator 17 and form foam scum, the efficiency of purification does not deteriorate even if the raw water is heavily contaminated.

The cleaning efficiency is dramatically improved because the water accumulates and floats to the surface as foamy scum.

躍的に向上ブる。(c) Since the foamy scum from the spiral vibrator 16 is pushed up from below by the floating blade of a large amount of foamy scum generated from the circulation vibrator 17, the force of pushing up the foamy scum to the liquid level at the upper end opening of the cyclone body 12 is increased. The dehydration and consolidation effect of the foamy scum is promoted, and the flotation separation effect is dramatically improved.

でき、設置スペースを著しく縮小できる。(e) In addition, during the recirculation of the liquid from the lower part of the cyclone body, the treated liquid is further violently stirred and mixed with air, and a large amount of foam consisting of fine air bubble particles is generated, and the treated water is mixed with the treated water. Because the contact with air is continuous, the aeration effect is strong, so there is less need to install special aeration equipment or biological treatment equipment than in the past. Therefore, the entire wastewater treatment system can be downsized, and the installation space can be significantly reduced.
