4 is a state in which one media filling chamber 6 shown in FIG. 2 is opened, and FIG. 2 is a compartment in which the media filling bag 6 is built by two media screens 1. The sections are divided into three sections, but in FIG. 4, the media filling rooms 6 are divided into five sections by four media screens 13, and the media filling rooms 6a, 6b, 6c, 6d, and 6e are illustrated. As such, it is shown that the media screen 13 partitioning the media filling room 6 may be partitioned by various numbers.

As shown in FIG. 4, the particle diameters of the media materials respectively embedded in the media filling chambers 6a, 6b, 6c, 6d, and 6e divided by the four media screens 13 are determined in the first media filling chamber 6a. The porosities are increased toward the fifth media filling chamber 6e, which is the first to the inflows distributed through the outlet holes 16 described later in the inflow water distribution pipe 10 in parallel to the arrow direction. This is to prevent the porosity from being blocked when passing through the media material of charcoal in the fifth media filling chambers 6a, 6b, 6c, 6d, and 6e.

And FIG. 6 is a detailed cutaway perspective view of the inlet inlet tube 1 of the inner settling tank 2 which is the core of the present invention. That is, the induction inlet pipe 1 is a cylindrical tube, which guides the inflow of the inlet water in a tangential direction between the inner surface 2a of the inner sedimentation tank 2 and the circular baffle 5a (in the direction of the arrow in the drawing). A precipitate is settled in the tank 4, and the inflow water is supplied to the inner cylinder part 5 through the cavity part of the circular baffle 5a.

Meanwhile, the filling tank upper blocking film 21 and the filling tank upper cover plate 20 are installed at the upper portion of the processing apparatus 102 of FIG. 2, and the inner precipitation tank 2 is disposed at the upper end of the inner cylindrical portion 5. When there is a lot of inflow flowing through the overflow pipe 19 is installed to bypass the discharge without entering the median filling room.

Next, a method of purifying the non-point pollutant using the present invention made as described above will be described.

As shown in FIG. 1, the initial rainfall inflow water is first purified in a known manner through the initial rainfall separation device 100 and the shear precipitation tank 101, and then the inflow water passing through the shear precipitation tank 101 is illustrated in FIGS. 2 is introduced into the internal sedimentation tank 2 of the treatment apparatus 102 shown in FIG. 2, in which the inflow water has a drop energy due to a difference Δh between the shear sedimentation tank 101 and the installation height of the treatment apparatus 102. The state enters the induction pipe 1 of the internal settling tank 2.

As the induction inlet pipe 1 is in tangential communication with the inner surface 2a of the inner settling tank 2 to introduce the inflow water into the inner settling tank 2, the inlet water flows inwardly through the inlet inlet pipe 1. It has a strong rotational force in the tangential direction between the inner surface (2a) and the circular baffle (5a) of the sedimentation tank (2) to rise to the inner cylindrical portion (5) through the cavity of the circular baffle (5a), The suspended particulate matter precipitated is stored in the sediment collection tank (4) through the inclined plate (3).

On the other hand, the rising influent flows in the direction of the arrow along one passage of the inner cylindrical portion 5 to discharge the influent toward the influent distribution pipe 10 and the overflowed inflow is through the overflow pipe 19. Let it discharge.

At this time, since the purification structure having the median filling chamber 6 is divided into two tanks by the filling tank separating partition 7, the inflowed water is also nutrient-treated at the same time.

The inflow water introduced into each of the inflow distribution pipes 10 is distributed through the outflow holes 16 of the inflow distribution pipe 10 into the first media filling room 6a and the second media filling room 6b, After being filtered while passing through the third media filling chamber 6c, adsorption is carried out by multiple media filled in the media filling chamber, and after the boiling point contaminants are removed, the treated water outflow screen 8 and the sump pipe 12 Collected through the sump (11) through the purified water is discharged.

As described above, the internal sedimentation tank of the non-point contaminant raw water treatment device according to the present invention has the advantage that the installation structure is simple and the sedimentation efficiency of the sediment is improved, as the inflow water clogging phenomenon is eliminated compared to the conventional internal sedimentation tank.
