Description

OIL AND WATER SEPARATION APPARATUS}

The present invention relates to a purifier, and more particularly, to separate oil or foreign substances contained in rainwater flowing along the road, melted snow, and water sprayed from a cleaning vehicle in an environmentally friendly manner, so that oil or foreign substances are not included. It relates to an oil-water separation device for discharging only water that is not.

Generally, both side surfaces of the road are provided with a plurality of side openings for collecting water flowing in the road at a predetermined distance.

The water collected in these outlets is a mixture of oil and other contaminants that remain on the surface of the road.

Thus, unpurified water mixed with oil and other contaminants collected through the side opening is collected in a manhole having a predetermined size and depth through the inlet pipe of the manhole.

The water collected in the manhole is purified by natural self-purification and sent to the river or sewage treatment plant through the drain pipe.

That is, the conventional manhole has a predetermined size and a certain depth, the inlet pipe to which the unpurified water is introduced into the upper end, and the discharge pipe for discharging the water purified by the gravity-type manure method.

Therefore, the unpurified water collected through the inlet pipe flows into the manhole, and after a certain time, sand, soil, dust, tire dust, garbage, etc. do not go to the bottom of the collecting manhole, and the water collected in the collecting manhole When a certain level is reached, only the first purified water is discharged through the drain pipe.

Round manholes are used because the shape of these manholes often needs to be opened and closed when problems arise in terms of maintenance and management.

However, since most of the residues left on oils and foreign matters floating on the water remain in the purified water, which is discharged through the conventional manholes, the water flowing into nearby rivers or rivers or collected in sewage treatment plants Highly contaminated

However, the rotary flow generating unit installed in such a naturally-purified manhole was easily broken or malfunctioned by foreign matter or garbage contained in the inflow water collected in the manhole.

In addition, the method of fixing the aerobic microorganisms had a problem that can not ensure the survival of the microorganisms. That is, since the influent itself is already contaminated with oil and does not contain much oxygen, a device for supplying oxygen is required for the survival of microorganisms.

In addition, the oil residue contained in the influent or floating foreign matter floating on the water has not been purified and discharged.

An object of the present invention is to solve the problems of the prior art mentioned above, after collecting the unpurified water containing oil and other contaminants through the inlet pipe, floating the various oil residues and floating on the water It is to provide an oil-water separation device that separates foreign matters in an environmentally friendly natural manner and discharges water from which oil components or foreign matters are separated through a discharge pipe.
