Next, the rainwater passing through the rainwater separation filter part 5 finally passes through the fiber filter plate 84 of the fiber filter part 8 formed on the other side of the drain 12, and the oil component contained in the rainwater. After the solid is filtered again, the purified rainwater is drained through the drain hole 12.

Therefore, the rainwater treatment device according to the present invention is provided with the steel recovery portion 15 and the steel suction portion 16 in the inflow portion of the rainwater to recover and remove the iron, such as iron pieces, nails, wires mixed in the rainwater Accordingly, the vertical filters constituting the filter screen unit 2 or the filters constituting the rainwater separating filter unit 5 are prevented from being damaged by contact with pieces of iron, nails, wires, and the like.

And the rainwater is removed as described above, the solid is physically removed while passing through the filter screen portion 2, the oil component of the fine particles and the solids of the fine particles are removed through the rainwater separation filter (5). Next, the oil component and the solids included in the rainwater are finally removed from the fiber filter part 8 again, thereby further improving the purification performance of the rainwater.

In addition, when cleaning the interior of the processing tank 1 after the rainwater is treated as described above, the vacuum pump connected to the steel suction part 16 in a state where the rainwater inside the processing tank 1 is discharged. By recovering the iron attached to the outer circumferential surface of the magnet-mounted horizontal tube 151 through the operation to collect and collect to the outside collecting space. Therefore, the rainwater treatment device of the present invention is also advantageous in that it can separate and recover only steel.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is clear that the present invention can be suitably modified and applied in the same manner. Therefore, the above description does not limit the scope of the present invention, which is defined by the limitations of the following claims.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention.
