The controller 50 drives the compressor 46 with the power generated by the solar cell 17 and switches the switching valves 47, 48, 49.

The switching valve 47 is connected to the discharge side of the compressor 46, the connecting pipe 52, and the connecting pipe 53, so that the discharge side of the compressor 46 communicates with the connecting pipe 53 without communicating with the connecting pipe 52. The state is switched to a state in which the discharge side of the compressor 46 communicates with the connecting pipe 52 without communicating with the connecting pipe 53. The switching valve 48 is connected to the connecting pipe 53, the air introducing pipe 31, and the air introducing pipe 32. The switching valve 48 communicates with the air introducing pipe 32 without communicating the connecting pipe 53 with the air introducing pipe 31.

The state is switched between a state of communicating with the pipe 54 and a state of communicating the connecting pipe 54 with the open-to-atmosphere pipe 55 without communicating with the connecting pipe 52.

Next, the operation of the water purification device 11 of the first embodiment will be described. When power generation is started in the solar cell 17, the driving of the controller 50 is started. Then, the controller 50 allows the switching valve 47 to communicate the discharge side of the compressor 46 to the connecting pipe 53 without communicating with the connecting pipe 52, and allows the switching valve 48 to introduce air without connecting the connecting pipe 53 to the air introducing pipe 32. A purification state is established to communicate with the pipe 31. Then, the power generated by the solar cell 17 is supplied to the compressor 46 so that the compressor 4
6 is driven.

Then, the compressed air generated by the compressor 46 is ejected from an air ejection hole (not shown) at the lower end of the air introduction tube 31 through the connection tube 53 and the air introduction tube 31, and becomes bubbles. The water moves upward from the bottom in the pumping pipe 28, so that an upward water flow is generated in the pumping pipe 28, the water in the internal gap 27 is pumped up from the lower end opening 28 a of the pumping pipe 28, and the upper opening 28 b Is discharged to the outside.

As a result, the purification processing unit 1
5, the water to be treated near the water surface 12a, which particularly contains a lot of algae such as blue-green algae, flows through the water passage holes (not shown) of the outer cylindrical portion 19, the water passage holes (not shown) of the upper plate portion 22, and the lower portion. The processing unit 2 reaches the processing unit 26 from a water passage (not shown) of the plate unit 20.
6 and moves inward to reach the internal gap 27 from a water collecting hole (not shown) of the water collecting pipe 23. Then, the processing unit 26
At the time of passing, aerobic microorganisms carried on the charcoal constituting the processing unit 26, algae such as blue-green algae and organic suspended matter,
The water to be treated is purified by decomposing the soluble organic substances and the like. In this way, the water to be treated, which has been purified by the treatment section 26, is again discharged to the outside from the pumping pipe 28, and the water area 12 to be purified is purified by such a reflux of the water to be treated.

On the other hand, at an appropriate washing timing during the cleaning process, the controller 50 causes the switching valve 47 to communicate the discharge side of the compressor 46 to the connecting pipe 53 without communicating with the connecting pipe 52 and to switch the connecting pipe 48 to the connecting pipe 53. 53
Without being connected to the air introducing pipe 31.
It is in a washing state to communicate with. Then, compressor 4
6 is connected to the connecting pipe 53 and the air introducing pipe 3.
The air is ejected from an air ejection hole (not shown) of the cleaning nozzle 34 via the nozzle 2, and the air becomes bubbles and moves mainly upward in the processing unit 26. Due to the friction caused by the movement of the bubbles,
Substances decomposed by microorganisms attached to the charcoal constituting the treatment unit 26 and suspended inorganic substances contained in the water to be treated are:
The processing unit 26 is separated from the charcoal by a water flow generated by the movement of bubbles.
Is transported outside. In this way, the substances accumulated in the processing section 26 are removed, and the processing section 26 is cleaned.

The compressor 46, the connecting pipe 5
3. The air introduction pipe 31 and the pumping pipe 28 constitute an air lift pump 56, and the compressor 46, the connecting pipe 53, the air introduction pipe 32, and the washing nozzle 34 constitute a washing device 57.

When a command signal for floating the anchors 36, 36 is sent from the outside to the controller 50, the controller 50 operates the switching valve 47 without connecting the discharge side of the compressor 46 to the connecting pipe 53. An anchor floating state is provided in which the connecting pipe 52 is communicated with the connecting pipe 54 without being connected with the atmosphere opening pipe 55 by the switching valve 49. Then, until then, Figure 2
As shown in (a), air from the compressor 46 is filled into the anchor float 38 on which the anchor 36 has been placed on the water bottom 12b with the air inside being evacuated, and the anchor float 38 has buoyancy. Occurs. As a result, as shown in FIG.
8 rises, and the anchor 36 also rises near the water surface 12a via the net 39.

Here, the controller 50 stops the compressor 46 when the compressor 46 is driven in the floating state of the anchor for a predetermined time required for filling the air in the anchor float 38 with air. Then, by setting the anchors 36, 36 in a floating state as described above, the water purification device 11 can be easily moved.

On the other hand, after moving the water purification device 11 to a predetermined position, when a command signal for lowering the anchors 36, 36 is sent from the outside to the controller 50, the controller 50 stops the compressor 47. As it is
The switching valve 49 allows the connecting pipe 54 to communicate with the atmosphere open pipe 55 without communicating with the connecting pipe 52. Then, the air filled in the anchor float 38 is released to the atmosphere from the atmosphere opening pipe 55, the buoyancy of the anchor float 38 decreases, and the weight of the anchor 36 increases.
Anchor 36 is net 39 and anchor 3
8 and settled on the water bottom 12b. By placing the anchors 36, 36 on the water bottom 12b in this manner, the water purification device 11 can be moored at a predetermined position. Then, after that, the controller 50 sets the switching valves 47 and 48 to the purification state, and drives the compressor 46 to perform the purification processing.

According to the water purification apparatus 11 of the first embodiment described above, when air is filled into the anchor float 38 when moving the same, the buoyancy of the anchor float 38 is increased. Then, the buoyancy causes the anchor float 38 to float together with the anchor 36. For this reason, it is possible to eliminate the manual work of lifting up the ropes 37, 37 connecting the anchors 36, 36 and the apparatus main body 13. Therefore, workability can be greatly improved.

Further, by using the above-described anchor float 38, when the compressor 46 is used on the apparatus main body 13 side as in this embodiment, the compressor 46 can be used, so that the cost is increased. Can be suppressed. In the case where the compressor 46 is not used on the apparatus body 13 side, the anchor 3 is used.
At the time of floating, a separate compressor is brought into the apparatus main body 13 and connected to the hose 41 to fill the anchor float 38 with air. In such a case, during normal cleaning processing and cleaning, It is preferable to provide a lid member that closes an opening for connecting the hose 41 to the compressor so that water does not enter the anchor float 38 during processing.

The winch 60 has a winch main body 61 for winding and unwinding the rope 37, and a handle 62 detachably attached to the winch main body 61.

If it becomes necessary to lift the anchor 36, the handle 62 is inserted into the winch main body 61 and the handle 62 is turned so that the rope 3
7 is wound up from one end, and the anchor 36 attached to the other end is floated up to near the water surface 12a.
In this way, the water purification device 11 can be moved by making the anchors 36, 36 float. On the other hand, after moving the water purification apparatus 11 to a predetermined position, the handle 37 is turned to pull out the rope 37 to settle the anchor 36 and place it on the water bottom 12b. In this way, the anchors 36, 36 are
The water purification device 11 can be moored at a predetermined position.
