して緑藻類を死滅させる方法等が採られていた。2. Description of the Related Art Conventionally, in order to remove green algae that have propagated in lake water, a flocculant such as aluminum sulphate is put into lake water, and the green algae are allowed to agglomerate and then aerated if desired. There have been adopted a method of floating an object on the surface of water and then sucking it with a vacuum pipe to collect it, or a method of adding copper sulfate to the water of a lake to kill green algae.

る。However, in the method of aggregating green algae and collecting them with a vacuum pipe, it is necessary to install a vacuum device or the like on the shore of the lake, which cannot be performed without such room. In addition, a large amount of coagulant is required, which is uneconomical. Furthermore, there are problems such as environmental pollution of the lake and its surroundings due to the coagulant, and since the water of the lake and marshes is also sucked in a considerable amount from the vacuum pipe, the removal efficiency of green algae is poor and the water of the lakes and marshes will decrease There is also a problem.

Is a lake, and water (2) in the lake (1) contains green algae (3)
Are breeding. The water (2) of the lake (1) is filled with a streamer-like net bag (4), and a floating plate with a pump (5) installed.
(6) can be floated. And as shown in FIG.
An injection pipe (7) fed from the outlet side of the pump (5) is connected to the opening at one end of (4), and the opening is connected to the wire (8).
Etc. Further, the opening at the other end of the mesh bag (4) is closed by a clip (9). The water absorption pipe (10) is inserted from the inlet side of the pump (5) and inserted into the water (2) of the lake (1), and the water absorption pipe (10) has water absorption pipe at the tip thereof. Net basket (11) to prevent inhalation from (10)
Is attached, and a cloth bag (12) filled with a coagulant such as aluminum sulfate is placed in the net basket (11).

い。When the mesh bag (4) is filled with green algae (3) or the mesh bag (4) is clogged, the operation of the pump (5) is stopped and the other end of the mesh bag (4) is stopped. Remove the clip (9) at the opening and connect the suction pipe (15) that is pulled out from the suction box (14) to which the suction pump (13) is connected to the opening as shown in FIG. Operate the pump (13) to activate the mesh bag (4)
Suck the green algae (3) in the suction box (14) into the mesh bag
Play (4). If there is no room to install a suction box (14) on the shore of the lake (1), raise the net bag (4) to the shore and open it to extrude and remove the green algae (3) in the net bag (4). May be.
Conversely, if there is room, the pump (5) may be installed on the shore, or the pump (5) may be installed in the water of the lake (1).
