As another technology, Korean Patent Publication No. 10-1826482 discloses a vertical pipe type rainwater filtering device.

In the above technology, rainwater flowing downward by the gravity of the vertical pipe is accelerated by gravity while receiving a deflection force along the inner surface of the funnel pipe of the Sanggwang Hagyeop (上廣下狹). The contaminants separated primarily along the downward slope of the mesh screen located at the bottom of the funnel tube are completely separated and drained to the outer space, and the rainwater from which the contaminants are removed is vertical through the mesh screen. It is directed to a vertical pipe-type rainwater filtration device that prevents clogging by contaminants in the pipe, and does not require frequent management, by dropping directly into the rainwater and flowing it into a separate rainwater storage tank.

Conventional non-point pollution source treatment facilities including the above-described technology have a complex structure for installing filters, so that maintenance is difficult.

Therefore, there is a need for a structure in which the filter installation is simple and at the same time secures the efficiency for the treatment of non-point pollution sources.

The sequence of performing filtration through the above-mentioned non-point pollution reduction facility is shown in [Table 4] below.

First, when rainwater flows in through the inlet, it flows into the pretreatment tank 1 and then flows into the filtration tank.

At this time, depending on design conditions, a rain sensor may be provided on one side of the inside or outside of the outer wall 10 to measure rain or rainfall to drive the facility according to the present invention.

Thereafter, the rainwater introduced into the filtration tank is granular filtered while passing through the fiber ball filter medium 100 due to the supply of air and the rise according to the accumulated amount of rainwater, and the filtered water is treated with clean water (treatment) in the backwashing tank 3 water) is introduced and discharged through the outlet (30).

On the other hand, depending on whether the rainfall sensor detects or not, when the detection is made by the rainfall sensor, it is determined that the water level rises, and the filtering process is continued.

Hereinafter, the backwashing process will be described with reference to [Table 5].

According to the backwashing fixation according to [Table 5], when 24 hours have elapsed from the end of detection by the rainfall sensor, the control panel operates the discharge pump 60 of the pretreatment tank 1 to drain the rainwater from the pretreatment tank .

At this time, rainwater and water from the filtration tank 2 may also be discharged together by the first communication hole, and when this procedure is completed, air is supplied through the air cleaning pipe 111 so that the lower plate 80 and The adsorbent remaining between the fiber ball media 100 stacked between the upper plates 90 or adsorbed on the surface is separated from the fiber ball media 100 .

After that, the discharge pump 60 is driven again to discharge the rainwater from the pretreatment tank and the filtration tank again, and then the water washing pump 70 of the backwashing tank 3 is driven to drive the water washing pump 70 from the upper side of the upper plate 90 to the filtration tank 2 ) to collect water to the lower side of the lower plate 80 , and operate the discharge pump 60 again to discharge water from the pretreatment tank 1 and the filtration tank 2 .

The characteristics of the fiber ball filter media 100 according to the present invention described above are shown in [Table 6].

On the other hand, in configuring the water washing pipe 71 described above, the bracket 200 is used at one side of the second communication hole of the second bulkhead so that the long pipe can withstand the vibration caused by the driving of the pump. The water washing pipe 71 may be fixed.

This is illustrated in FIG. 3 of the accompanying drawings.

3 shows another example of a non-point pollution treatment facility using a fiber ball filter material according to the present invention.

Meanwhile, according to other design conditions, the bracket 200 may be configured as shown in [Table 8].

The bracket 200 according to [Table 8] includes: a first body 210 including wings in both directions in a hemispherical shape; a second sieve 220 positioned in a direction symmetrical to the first sieve 210; a spring coupled (bolting, welding, bonding, etc.) between the opposite wing of the first sieve and the second sieve; and a coupling plate 230 positioned through a through hole formed in each of the other wing facing each other of the first sieve and the second sieve.

At this time, one side of the coupling plate 230 includes two bolt holes.

In addition, a coupling groove 51 corresponding to the size and shape of the coupling plate 230 of the bracket 200 is formed on the lower surface of the second partition wall 50; It is formed concavely upward from the coupling groove 51, and is configured to include two wing grooves 52 into which a portion of the wings of the first and second sieves are interpolated.

According to this configuration, first, after fixing the water washing pipe 71 using the bracket 200, and then inserting the coupling plate 230 into the coupling groove 51 while penetrating the through hole of the bracket, the bolt is tightened. By using the coupling plate 230 to the lower surface of the second partition wall, the bracket 200 is fixed.

At this time, the coupling plate 230 will be adjacent to the upper side of each through hole of the bracket by gravity, and the wings of the bracket will be interpolated so as not to completely fill the wing grooves 52 .

After that, when vibration is generated by the water washing pump 70, the through-hole of the bracket vibrates in the up/down direction, and the water washing pipe 71 maintains a predetermined durability despite the vibration caused by the driving of the water washing pump. It has the advantage of being able to have it.

What has been described above using the drawings is to describe only the main points of the present invention, and it is obvious that the present invention is not limited to the configuration of the drawings as much as various designs are possible within the technical scope.
