規模なものとなる。As a method of improving the water quality in a water area, it is well known that oxygen is supplied into water by aeration stirring to create a water flow. However, if the water is colored, or if there are many suspended solids in the water and it is cloudy, there is a limit to improving the water quality only by aeration and stirring. For this reason, it has been known that ozone treatment is very effective for coloring water and coagulating sedimentation treatment is extremely effective for removing turbidity. However, since equipment and facilities for this ozone treatment and coagulation sedimentation treatment are separately provided, the equipment cost becomes large and the equipment becomes large-scale.

In the figure, P is a pond, a lake or the like (hereinafter referred to as a pond) having a required shape, size, and capacity,
As shown in FIGS. 2 and 3, the aeration apparatus is installed in the pond P so that the water in the pond is stirred and a circulating water flow is generated. This aerator also aerates the water in the water area, and various types such as a propeller type mixer and a screw type aerator can be adopted, but the aerator shown in the figure floats on the main body frame 1 as shown in FIG. 2 is provided so that the entire aeration device can float.

The air is sucked in from the end of the ventilation pipe, and is discharged into the water through the hollow shaft.

The coagulant tank 13 storing the condensed coagulant liquid is connected, and the other branch pipe is connected to the ozone generator 10 via the switching valve 12 and the control valve 11, and the supply amounts of ozone and the coagulant are respectively controlled by the control valve. It is adjusted by 11, 14 and switching between ozone and a coagulant is performed by opening and closing the switching valves 12, 15.

調節弁１４を開いて凝集剤を所要量を添加する。Therefore, when the apparatus constructed as described above is arranged at a predetermined position in the water area P and the aeration apparatus is operated, the water in the water area is aerated by stirring and oxygen is supplied to the water, whereby the organic suspension is generated. The substance undergoes aerobic decomposition. However, pollutants suspended in water, mainly algae, repel each other and float because they have the same electric charge (usually negative) on their surface, and they do not settle easily. In order to accelerate this precipitation, the aeration device is driven and the switching valve 15,
The control valve 14 is opened and the required amount of flocculant is added.

多くなる。This is sucked from the coagulant storage tank 13 installed on the ground by the negative pressure in the water area by the aeration device,
Stir at the same time in the water. Then, the coagulant is added while stirring the water in the water area.At this time, the light transmittance of the water in the water area is detected by the spectrophotometer, and when the predetermined value is reached, the signal from this spectrophotometer is used. Thus, the switching valve 15 is closed to stop the addition of the coagulant, and the aeration device is also stopped for a certain period of time to allow the flocculated material to settle down due to the coagulant effect. Regarding the relationship between the coagulant addition rate and the stirring flow rate, the larger the stirring flow rate, the larger the amount of the coagulant added.

The flow rate is adjusted by the control valve 11 to supply the ozone amount suitable for the water quality of the water area. The suction of ozone is also carried out by utilizing the negative pressure of the screw as in the coagulant.
