The oil and water separation body 10 is made.

As shown in the prior art, the mixer 3, the pressurized tank 4 and the oil / water separator main body 10 are provided separately, and water, air and oil are separated into the three phases in the pressurized tank, followed by oil / water separation. It is supplied to the main body 10 so that the oil component is floated to separate the oil water.

However, in the case of the prior art, all the major components are separated, and since the water, air and oil must be separated into three phases in the pressure tank, there is a problem in that the configuration is complicated and the apparatus is too large.

In addition, the related art has a problem in that an air compressor must be provided because the compressed air is mixed with the waste water by supplying compressed air by the air compressor 1 to the mixer and simultaneously pressurizing the waste water.

In addition, it is impossible to generate fine bubbles by supplying compressed air to the wastewater, and the air has a problem of contacting only part of the wastewater.

The contaminated water flowing into the second flow path P2 flows downward and is moved to the third flow path P3 formed between the second partition wall 140 and the third partition wall 150. That is, in the third flow path P3, the contaminated water flows upward again.

The contaminated water moving along the third flow path P3 is mixed with the microbubbles generated by the microbubble generator 160, and the contaminants contained in the contaminated water are separated from the water by contact with the microbubble and thus the third bubble. It is collected in the upper portion of the flow path (P3).

The contaminated water moving along the third flow path P3 flows over the baffle 151, which is the upper end of the third partition wall 150, to the fourth flow path P4, and is disposed on the upper portion of the third flow path P3. Pollutants that are collected are forcibly sucked through the intake pipe 170 and discharged. Therefore, the water moved to the fourth flow path (P4) is treated water in a state in which a considerable amount of pollutants have been removed, and once again passing through the second filter 20 provided in the fourth flow path (P4), the pollutants are removed. Removed. The treated water that has passed through the second filter 20 is discharged through the treated water outlet 120.

Through the above process, the contaminated water can be purified to the treated water very smoothly, and this process occurs in one chamber to generate the treated water, thus providing a very compact oil-water separator for treating contaminated water. .
