And a pretreatment pump 123 connected between the supply pipe 122 and pumping the raw water of the raw water storage tank 110 to the first ejector 130. Therefore, when the pretreatment pump 123 is operated, the raw water of the raw water storage tank 110 is supplied to the first ejector 130 while flowing through the suction pipe 121.

The first ejector 130 supplies ozone to the raw water to sterilize the raw water supplied by the raw water transfer unit 120. As shown in FIG. 2, the first ejector is positioned at the bottom of the reduction tube 131 and the reduction tube 131 where the end of the supply pipe 122 is connected and the neck portion of the upper portion is gradually reduced. It is positioned between the enlarged tube 133 and the reduced tube 131 and the enlarged tube 133 to be enlarged and consists of an ozone inlet 132 through which ozone is introduced. Accordingly, when the raw water flowing into the first ejector 130 through the supply pipe 122 passes through the reduced diameter portion of the reduction pipe 131, the flow rate becomes very fast, and a vacuum phenomenon (critical phenomenon) occurs instantaneously, and ozone inflow. The ozone flowing into the unit 132 is strongly sucked and mixed. Thereafter, the ozone water passing through the enlarged tube 133 passes through the neck portion which is gradually enlarged, and a strong flow rate is changed to a pressure to oxidize contaminants contained in the raw water while the ozone mixed in the raw water is dissolved under pressure.

The filtration device 440 is for discharging the third treatment water separated from the ozone bubble separator 430 to the outside, and the primary filtration tank 441 and the secondary filtration tank for filtering the sludge contained in the third treatment water ( 442).

The primary filtration tank 441 is pumped by the filtration water pump 443 to filter the sludge from the tertiary treated water. In this case, the primary filtration tank 441 may include a sand layer in which sludge is filtered. Therefore, the supernatant passes through the sand layer of the primary filtration tank 441 from the top to the bottom, and the sludge is filtered by the sand layer.

The secondary filtration tank 442 filters the fine sludge in the filtered water filtered in the primary filtration tank 441. Here, the secondary filtration tank 442 may be configured to include an activated carbon layer to filter fine sludge. Therefore, the first filtered filtrate passes through the activated carbon layer from the top to the bottom, so that the fine sludge is filtered by the activated carbon layer once more.

Filtrate discharge pipe 450 is connected in the secondary filtration tank 442 to finally discharge the filter filtration filtrate to the outside.

In this way, the supernatant is continuously filtered by the primary filtration tank 441 and the secondary filtration tank 442, so that sludge and fine sludge are filtered out, so that clean water can be discharged to the outside.
