Subsequently, the rainwater that extends over time is introduced into the oil adsorption tank 300 formed by the first partition 240 and the second partition 340 beyond the upper end of the first partition 240. At this time, the rainwater introduced is purified by the oil filter 310, the oil contained in the rainwater.

The first purified rainwater is discharged to the filter support plate 320 formed at the lower end of the oil filter 310. Subsequently, the discharged rainwater flows in the direction of the second partition wall 340 by the inclination of the fermentation plate 320, and the second partition wall 340 has an outlet hole 330 formed therein to be primarily purified. Can be discharged through the outlet hole 330.

At this time, the location of the outlet hole 330 is formed in the contact portion of the second partition wall 340 and the fertilization plate 320 is not discharged to the discharge hole 330 without remaining in the fertilizer plate 320. .

Subsequently, the rainwater discharged to the outlet hole 330 is introduced into the purification filter 450 inserted into the center of the purification base plate 420 once again to perform secondary purification.

At this time, the rainwater accumulated on the top of the purification plate 420 over time is introduced into the purification filter 450 along the flow path groove 460 having the inclination angle formed of the purification plate 420, the purification plate. Water is not always accumulated at the top of 420.

At this time, the purification filter 450 inserted in the center of the purification plate 420 is a purge filter protruding from the upper end of the purification filter 450 inserted in the center of the purification plate 420 because rainwater flows from the bottom surface ( The rainwater does not flow into the 450, and secondary purification is performed through the purification filter 450 protruding from the lower end thereof.

The rainwater that has been purified second is discharged to the lower end of the purification base plate 420, and is discharged through the discharge port 410. At this time, the inclined plate 440 having a predetermined inclination angle is installed on the bottom surface of the filter filtration tank 400 so that all the rainwater on the bottom surface is discharged to the outlet 410 along the inclined plate 440.

In this case, water is not accumulated in the oil adsorption tank 300 and the filter filtration tank 400 so that the water is always frozen in winter to freeze and prevent freezing.
