Description
【発明の詳細な説明】 （産業上の利用分野） 本発明はアオコの処理方法に関するものである。[Detailed description of the invention] (Industrial application field) The present invention relates to a method for treating blue-green algae.
（従来技術）
従来アオコ処理は湖沼の原水を陸上に設置した処理槽に
導き、そこでフィルターやベルトプレス等で濾過するか
、又は浮上分離法による処理が行われているが、アオコ
を除去した後の清澄な水は再び湖沼に戻すものである為
、折角湖沼をきれいにしても原水が希釈されるだけで、
実際の浄化処理能力は不十分なものであった。(Prior art) Conventionally, algal bloom treatment involves directing raw water from lakes and marshes to a treatment tank installed on land, where it is filtered using a filter, belt press, etc., or by flotation separation method. Since the clear water of the lake is returned to the lake, even if we take the trouble to clean the lake, the raw water will only be diluted.
The actual purification capacity was insufficient.
（発明の目的）
本発明の目的は上記のような欠点を除去したアオコの処
理方法を得るにある。(Object of the Invention) The object of the present invention is to obtain a method for treating blue-green algae that eliminates the above-mentioned drawbacks.

ことを特徴とする。(Structure of the Invention) The method for treating blue-green algae of the present invention includes a step of spouting a treatment agent into a lake or marsh from which blue-green algae is to be collected via a treatment boat, a step of stirring this spouted portion through a treatment boat, and a step of stirring the sprayed part through a treatment boat. The method is characterized by comprising a step of ejecting pressurized water to the part via a processing vessel to create fine air, and a step of moving the processing vessel.
（発明の実施例） 以下図面によって本発明の詳細な説明する。(Example of the invention) The present invention will be explained in detail below with reference to the drawings.

パイプを通して散布ノズル５より湖沼内に噴出せしめる
。In the present invention, as shown in FIGS. 1 to 3, a pressurized water tank 2 and a treatment agent tank 3 are placed on the upper part of a barge l equipped with a propeller 9, and from the treatment agent tank 3, for example, clay minerals and Ah ( h and F
A treatment agent consisting of a powdered reaction product of e and O with an inorganic acid is sprayed into the lake from a spray nozzle 5 through a pipe.
又噴出と同時にモーター７によって攪拌機４を駆動し、
処理剤を湖沼内の原水と混合せしめる。Also, at the same time as the ejection, the agitator 4 is driven by the motor 7,
The treatment agent is mixed with the raw water in the lake.
次に空気を溶解した加圧水を加圧水槽２より導き集合管

上する速度が加速されるようになる。Next, pressurized water containing dissolved air is introduced from the pressurized water tank 2 and is ejected into the lake from a valve 8 provided in the collecting pipe 6 to create fine air. This fine air adheres to the flocculated blue-green algae and increases the buoyancy of the blue-green algae.As a result, the apparent specific gravity of the blue-green algae decreases, and the speed at which the blue-green algae floats to the surface of the lake is accelerated. become.
向上記台船は速度１〜２ｍ／分程度で前進、後進を繰り
返すことにより散布、攪拌浮上を連続的に行うことが出
来、又散布、攪拌・浮上の装置に昇降装置を組み合わせ
ることで水深の変化に対応出来る。By repeatedly moving forward and backward at a speed of about 1 to 2 m/min, the barge can continuously perform spraying and stirring and flotation, and by combining the spraying, stirring and flotation equipment with a lifting device, it is possible to adjust the depth of the water. Able to respond to change.

プの下部に水平に配置したものとするのが好ましい。The above-mentioned dispersion nozzles 5 are vertically spaced apart from each other in pipes vertically installed in parallel with each other and spaced apart from each other.
Preferably, a large number of blades are provided on a pipe arranged in parallel with the pipe provided with the spray nozzle 5, and the collecting pipe 6 is arranged horizontally below these pipes.
（発明の効果）
本発明方法は上記の通りであるから湖沼の大小に拘らず
直接湖沼の原水を処理の対象とすることが出来、従来の
方法に比べて大量の水を処理することが出来る大きな利
点がある。(Effects of the Invention) Since the method of the present invention is as described above, it is possible to directly treat the raw water of lakes and marshes regardless of the size of the lake, and it is possible to treat a large amount of water compared to conventional methods. There are big advantages.
