The arrangement and the number of package-type filtration device 220 located in the filter paper 200 is adjustable, it is preferable that the arrangement is provided in various ways depending on the situation of the field and influent, such as in series, parallel. Do.

Here, since the initial excellent water contains a high concentration of non-point pollutants in a short time and flows out, the filtration speed in the filter paper 200 should be fast, and thus, a medium having a high filtration speed and a high pollutant removal efficiency should be selected. 30, the particle size should be larger than a certain size, and the porous media 230 having a lot of internal pores of the particles is essential, and the porous media 230 has good filtration efficiency because filtration and adsorption of fine particles occur in the interior of the pores. Its use has a long effect.

Hereinafter, the process of the initial excellent water flowing into the pipeline-type initial excellent treatment device according to the present invention will be described in detail.

In the early stages of raining, various kinds of pollutants contained in roads, soils, etc. are introduced into rainwater pipelines. At this time, the characteristics of the initial rainwater introduced are mainly due to the high concentration of non-point pollutants and the low flow rate, so that the initial rainwater flowing into the rainwater pipe 500 flows into the pipeline-type initial rainwater treatment device installed at the bottom of the rainwater pipe, While flowing through the stepped aeration passage 110 formed in the inlet portion of 100 to precipitate a variety of heavy non-point pollutants.

At this time, by supplying air from a plurality of blowers 240 installed in the lower portion of the filter paper 200, it is possible to increase the filtration and adsorption efficiency of the treated water, where the sludge precipitated a certain interval between the wall and the bottom surface of the filter paper (200) It moves along the inclined bottom surface through the vacant space and is introduced into the sludge storage tank 120.

And the treated water treated in the sedimentation basin 100 is installed between the sedimentation basin 100 and filter paper 200 A plurality of package-type filtering devices 220 are introduced into the filter paper 200 by passing through the plurality of through-flow holes 260 formed in the wall of the rectifying wall 210 and installed in series or in parallel in the filter paper 200. ), Various non-point pollutants contained in the treated water are filtered and adsorbed by the filter medium (230) filled in the c) and discharged through the backflow prevention door (300) to the existing rain pipe (500).

That is, the initial excellent water containing the non-point pollutant introduced into the filter paper 200 passes through the media 230 accommodated therein through the lattice hole formed in the package-type filtration apparatus 220, and thus the non-point pollutant. After the material is removed by the filtration adsorption settling, the filtered treated water is discharged to the rain pipe to flow through the backflow prevention door (300).

In the present invention, the backflow prevention door 300 discharges the treated water treated in the filter paper 200 to the existing storm pipe as shown in FIG. 10, and the rainwater or pipe-type initial flows along the storm pipe 500. The treated water flowing out through the rainwater treatment device serves to block the flow back into the device in the reverse direction. The backflow prevention door 300 is connected to the distal end of the upper cover 400 is operated to open and close, and when rainwater is reverse flow rainwater pipe line 500 adjacent to penetrate the space discharged from the treated water of the filter paper (200) In order to prevent the backflow prevention door 300 to operate in the reverse direction by forming a catching jaw 420 in the position of the bottom of the rain pipe (500) corresponding to the position where the backflow prevention door 300 is located in the bottom surface of the. .

In this case, after the initial rainwater is treated through the above process, the rainwater flowing in due to the continuous rain contains less non-point pollutants unlike the initial rainwater, but the flow rate flowing into the rainwater pipe 500 is Since the treatment flow rate of the filter paper 200 is exceeded, the rainwater exceeding the treatment capacity is discharged through the upper portion of the filter paper 200 directly from the settler 100.

In other words, when the initial type excellent rainwater treatment device according to the present invention is introduced into the rainwater pipeline 500, the rainwater flows into the pipelined initial rainwater treatment device as shown in FIG. The upper cover 400 is formed so that the rainwater flow exceeding the design capacity on the upper portion of the filter paper 200 due to the treatment and continuous ratio is bypassed to the rainwater pipe like the B flow without passing through the filter paper 200. It provides a maintenance door 410 for the replacement of the package-type filtration device 220.

Therefore, the pipeline-type initial excellent treatment device according to the present invention having the structure as described above can protect natural ecosystems such as rivers, lakes, and ports through the prevention of water pollution caused by nonpoint pollutants discharged from a wide range of nonpoint sources. In particular, it is possible to efficiently secure the space of the installation site by installing the pipeline type initial excellent treatment device at the bottom of rainwater pipes, and it is easy to install and maintain. Due to this, it is possible to treat sewage that flows in.
