<p>PURPOSE:To surely capture an alga or the like generated in the neighborhood of a water surface by supporting a water collection body with a floating body in the neighborhood of the water surface. and performing purifying treatment by sucking water to be treated in the neighborhood of the water surface by a pump and introducing it to a treatment layer equipped with charcoal which carries a microorganism. CONSTITUTION:A drain pipe 38 is connected to the drain port of the pump 14 on which the floating body 36 is mounted, and also, the communication hole of a purifying treatment unit on which the floating body 36 is mounted is connected to the supply port of the pump 14 via a regular pipe 43. A purification treating device main body 12 comprised in such way is formed by setting the axial direction of a water collection pipe 21 in almost parallel with the water surface, and also, the drain pipe 38 is floated on the water surface by opening in the neighborhood of the bottom of a lake 11. A pump 14 is driven, and the water to be treated containing sufficient quantity of oxygen in the neighborhood of the water surface is sucked in the purification treating unit 13 with the alga or the like in the neighborhood of the water surface, and the purifying treatment is performed by running the water by supplying oxygen to the microorganism on the charcoal on the layer to be treat of the unit 13, and disposal water collected in the water collection pipe 21 is discharged from the drain pipe 38 to the neighborhood of the bottom of the lake.</p> |
