On the other hand, the order of washing the disk filter 70 and the fiber filter 72 in the backwashing type non-point pollution reduction device having a multi-layered filter according to the present invention is as follows.

First, the disc filter 70 and the fiber filter 72 are checked through the observation part 90, and when the disc filter 70 and the fiber filter 72 need to be cleaned, the inlet pipe 28 and the filtered water are discharged. When the pipe 48 is switched to closed, and the inlet pipe 28 and the filtered water discharge pipe 48 are switched to closed, the cylinder 58 is operated as shown in FIG. 6 and the high pressure is supplied through the air supply hole 30. Air is supplied to the washing of the disc filter 70 and the fiber filter 72, and the cylinder 58 is operated several times up and down to facilitate smooth washing of the disc filter 70 and the fiber filter 72. When the cleaning of the disc filter 70 and the fiber filter 72 is finished, the washing water is discharged through the washing water discharge pipe 38.

At this time, the water for first washing the disk filter 70 and the fiber filter 72 is an initial good, and after the first cleaning of the disk filter 70 and the fiber filter 72, the water pump 74 is operated. After supplying the filtered initial good water inside the filtered water storage unit 82 to the filtered unit 36 through the filtered water receiving unit 46, the cylinder 58 is operated as shown in FIG. 6 and the air supply hole 30 is provided. The high pressure air is supplied to the second cleaning of the disc filter 70 and the fiber filter 72, and the cylinder 58 is operated several times up and down, of the disc filter 70 and the fiber filter 72. It is intended to facilitate smooth cleaning, and when the second washing is finished, the washing water is discharged through the washing water discharge pipe 38 as in the first.

Meanwhile, the second washing may be repeated several times by checking the states of the disk filter 70 and the fiber filter 72 through the observation unit 90.

The backwashing type non-point pollution reduction device having the multi-layered filter according to the present invention made as described above is simply formed, and the disk filter is formed by forming a multi-layered contaminant and soluble contaminants in the initial water flowing inward. (70) and can be easily collected by the fiber filter (72), when the contaminants on the multi-layered disc filter (70) and fiber filter (72) saturate, supplying water and air, as well as the disc filter The disk filter 70 and the fiber filter 72 can be easily washed and reused by reciprocating the filter 70 and the fiber filter 72 up and down using the cylinder 58, as well as the disc filter 70. And even when the fiber filter 72 is damaged, the disc filter 70 and the fiber filter 72 that are easily damaged can be replaced.
