物から成る処理剤を注入し、この処理剤と上記送水され
た原水を処理枠１への流入直前混合しながら上記集合管
２の下部にあけられた多数の孔から落下せしめる。In the present invention, as shown in FIGS. 1 to 4, four side surfaces and a bottom surface are surrounded by a waterproof sheet, and a treated water outlet is formed on one side surface, for example, a rectangular shape having a length of 15 m, a width of 4 m, and a height of 1.2 m. The treatment frame 1 is installed at one end of the pond and the submersible pump 9 is installed at the other end of the pond.
Is arranged to feed the raw water (untreated water in the pond) to both ends of the collecting pipe 2 having a large number of lower holes arranged on the upper side of the treatment frame 1 on the side facing the treated water outlet. . A treating agent composed of a powdery reaction product of, for example, a clay mineral and an inorganic acid of Al 2 O 3 and Fe 2 O 3 is injected into the collecting pipe 2 through a treating agent injection pipe 3, The fed raw water is mixed immediately before flowing into the treatment frame 1 and dropped from a large number of holes formed in the lower part of the collecting pipe 2.
更に上記処理枠１内には上記集合管２からの混合液を処
理枠１の他の区域より仕切るための孔あき整流板４を設
け、上記混合落下した水をこの整流板４にあけた多数の
孔を通して処理枠１内の他の区域に導く。Further, a perforated rectifying plate 4 for partitioning the mixed liquid from the collecting pipe 2 from the other area of the processing frame 1 is provided in the processing frame 1, and a large number of the mixed and dropped water is opened in the rectifying plate 4. Through other holes in the processing frame 1.
この結果混合水は整流板４の前では急速攪拌、後では緩
速攪拌の状態を呈し極めて良い凝集条件を作り出すので
アオコの大きな凝集フロックが生ずる。As a result, the mixed water exhibits a state of rapid agitation before the straightening vanes 4 and a state of slow agitation afterwards and creates extremely good aggregating conditions, resulting in large agglomerated flocs of water-bloom.
更に上記処理枠１内の他の区域には上記整流板４に隣接

処理枠１内を上記処理水流出口に対向する側（上流側）
から上記処理水流出口が形成されている下流端に向かっ
て流れながら浮上するが、下流端に到着するまでには完
全に浮上が終了する。Further, a pressurized water jet pipe 5 is provided in the other area of the processing frame 1 adjacent to the straightening vane 4, and the flocculation flocs passing through the holes of the straightening vane 4 are provided with a pressurized water feed mechanism (not shown). Then, fine bubbles of the pressurized water ejected from the pressurized water ejection pipe 5 are adhered and forcedly levitated. The flocculation floc is a side in the treatment frame 1 that faces the treated water outlet (upstream side).
From the above to the downstream end where the treated water outlet is formed, while floating, but by the time it reaches the downstream end, the floating is completely completed.
従って処理枠１の下流端上部には水面より約2cm程度下
側に開口せしめた回収箱６を設け、この回収箱６内へ凝
集フロックを連続的に流し込み、それをバキューム機構
７で吸引し処理枠１外へ排出する。Therefore, a recovery box 6 opened about 2 cm below the water surface is provided above the downstream end of the processing frame 1, and flocculation flocs are continuously poured into the recovery box 6 and suctioned by a vacuum mechanism 7 for processing. Discharge out of the frame 1.
尚滅多にないことであるが、どうしても浮上しないアオ
コのため上記処理枠１内の下部に上記回収箱６に近接し
て底面から所定の高さに延びる流出防止膜８を設けて一
旦止めておき後で除去するようにするのが好ましい。Although it is rare, since the water-bloom does not float by any means, an outflow prevention film 8 extending from the bottom surface to a predetermined height is provided in the lower part of the processing frame 1 in the lower part of the processing frame 1 and temporarily stopped. It is preferable to remove it later.
又本発明においては第４図に示すように上記処理枠１に

うに両者間を仕切膜10で仕分ける。Further, in the present invention, as shown in FIG. 4, the treated water is treated by the treatment frame 1, and the treated water flows out of the treated frame 1 through the treated water outlet, but the treated water of the submersible pump 9 is not treated. The partition membrane 10 separates the raw water so that it does not mix with the raw water.

膜10を移動せしめるようにする。For example, as shown in FIGS. 5 and 6, the partition film 10 uses a waterproof sheet 13 having a float 11 on the upper portion and a chain 12 on the lower portion, and the waterproof sheet 13 can be replenished in the longitudinal direction by a fastener 14. Partition membrane for its use
10 is installed near the treatment frame 1 so that the partition membrane 10 can be moved as the treated water increases.
本発明のアオコの処理回収装置は上記の通りであるから
湖沼の条件に合わせて自由に処理枠の大きさを定めるこ
とが出来、この処理枠は水中に設置するものであるため
陸上の場所をとらず、又剛性も不要のため、従来方式に
比してコストの低減が出来る大きな利益がある。Since the apparatus for processing and recovering water-bloom of the present invention is as described above, the size of the processing frame can be freely determined according to the conditions of lakes and marshes. In addition, since it does not require rigidity, there is a great advantage that the cost can be reduced as compared with the conventional method.
