In addition, although not shown in the transfer screw 12, a cleaning element such as a brush is additionally installed to transfer while sweeping coarse contaminants and sediment contaminants attached to the screen body (11).

That is, the screw screen 10 composed of such a screen body 11 and the transfer screw 12 is the initial that the screen body 11 is directly connected to the combined sewer pipe (2) containing coarse contaminants and sediment contaminants. The rainwater is excluded from the water supply, and the transfer screw 12 rotates without a force to transfer coarse contaminants and sediment contaminants that are excluded from the screen body 11.

Preferably, the screw screen 10 is provided to be mounted in the inner installation space 16 of the water supply unit 15 and the housing 14 formed in a structure capable of draining it, which is the external element transfer screw 12 In order to prevent the influence of the operation of the water supply and the initial excellent water supply only through the combined sewer pipe (2) to prevent the generation of the initial excellent water supply exceeding the expected design range.

Accordingly, the screw screen 10 is connected to the combined sewer pipe 2 through the water supply unit 15, and the upper and side surfaces of the screw screen 10 are closed to the inner installation space 16 of the housing 14 in which only a part of the lower part is opened. This will eliminate coarse contaminants that are included in the initial stormwater and sediment contaminants that joined during the initial stormwater supply.

The initial rainwater passing through the screen body 11 during the initial water supply of such excellent water falls and is supplied to the cylindrical screen 20, and the coarse contaminants and sediment contaminants caught by the screen body 11 are removed by the initial rainwater. It is fed by the driven screw 12 is supplied to the contaminant discharge pipe (17).

In the conveying process of the floating may not be smooth transfer.

In addition, the initial rainwater accumulated at the tip of the screen body 11 together with the coarse contaminants and sediment contaminants may be discharged through the contaminant discharge pipe 17, which may cause a variety of problems such as a burden on the sewage pipe 4 or the sewage treatment plant. have.

On the contrary, when the front end of the screw screen 10 is installed upwardly inclined upward, the initial excellent water does not accumulate at the front end of the screen body 11, thereby easily discharging coarse contaminants and sediment contaminants through the transfer screw 12. It can be done, and unnecessary drainage of the initial excellent water will not occur.

A more preferred embodiment for satisfying this is to form the tip of the screen body 11 in a wedge shape to double the tilting effect.

Therefore, the radial initial rainwater treatment device 1 buried in the natural river or the nearby sea where frequent storms frequently occur is installed with the screw screen 10 inclined upwardly, and coarse sediments and sediments included in the initial rainwater are deposited. It is desirable to avoid contamination of the contaminants and transportation.

When the screw screen 10 as described above is installed in a large number in the installation space 16 of the housing 14, in particular, when installed in parallel, it is obvious that the exclusion efficiency of the coarse coarse particles contained in the initial superiority can be further increased. That's one thing.

The clutter discharge pipe 17 has one end connected to the screen body 11, the other end is connected to the vortex 21 to be described later, the coarse contaminant and the sediment contaminant are transferred to the vortex 21 by the transfer screw 12. Finally it is utilized for the purpose of being discharged to the sewage treatment plant through the sewage pipe (4).

The contaminant discharge pipe 17 is a known transfer pipe, and the other end is connected to the vortex 21 in a state where one end is connected to the front end discharge pipe 11a protruding from the front end of the screen body 11 to transfer the screw 12. It has been shown to discharge the coarse coarse sediment and sediment contaminants transported through free fall.

Cylindrical screen 20 according to the present invention is to exclude the intermediate impurities in the initial excellent water supplied through the screw screen (10).

That is, the cylindrical screen 20 is provided with a screw screen 10 or a housing 14 mounted therein at the top in a state where the whole is formed into a net and receives an initial excellent water from which coarse contaminants of 5 mm or more are excluded. Less than 5mm in the initial excellent, 3mm or more intermediate contaminants are excluded, and this excluded intermediate contaminants are spontaneously settled and discharged inside the cylindrical screen 20.

Therefore, the initial excellent water supplied through the screen body 11 in a state where coarse contaminants and sediment contaminants are excluded through the screw screen 10 is gradually filled in the inside of the cylindrical screen 20 and drained to be described below. Water is supplied to the curtain screen 30, in this process the intermediate contaminants in the initial excellent is to be excluded by the cylindrical screen (20).

Curtain screen 30 according to the present invention is radially installed around the cylindrical screen 20, the filtering element 31 is disposed inside the fine contaminant in the initial excellent water flowing through the edge of the cylindrical screen 20 It is used for the purpose of excluding by decreasing the flow velocity due to the increase of the cross-sectional area.

Although the curtain screen 30 is fixed to the circumference of the cylindrical screen 20 by welding or the like, it is possible to exclude fine contaminants, but in a preferred embodiment, as shown in FIGS. 1 to 3, the cylindrical screen 20 The curtain screen 30 is detachably installed on the fixing frame 32 while the radial fixing frame 32 is installed at the circumference.

The fixing frame 32 is rotatably installed around the cylindrical screen 20 through a rotating element 30b such as a bearing, so that the radial initial excellent treatment device 1 according to the present invention is placed in a narrow space such as a roadside or a sidewalk. When installing, in particular, the upper manhole cover for maintenance is to be able to separate the curtain screen 30 while rotating the fixing frame 32 from the outside, even if a small scale that does not expose the entire initial radial excellent water treatment device (1) to the outside .

Accordingly, if necessary, the curtain screen 30 can be easily and simply separated from the cylindrical screen 20 to be freely cleaned or replaced. To further facilitate the curtain screen 30, a handle 33 is formed on the top of the curtain screen 30. Is showing.

More preferably, the curtain screen 30 is divided and installed around the cylindrical screen 20, so that only a part of the curtain screen 30 can be replaced without replacing the entire curtain screen 30 when cleaning or replacing as necessary. Therefore, the replacement cost can be reduced, as well as the convenience of replacement.

The filtering element 31 disposed on the curtain screen 30 is attached to the carrier and the filter medium so as to effectively filter out fine contaminants smaller than 3 mm included in the initial excellent water. The carrier and the media are accommodated in the interior of the curtain screen 30 to allow the exclusion of sequential fine contaminants.

More preferably, as shown in FIGS. 3 to 4, the curtain screen 30 is disposed inside the curtain screen 30, that is, close to the cylindrical screen 20, and the curtain screen 30 has a significantly reduced flow rate. Outside the) will be placed a microcarrier or micro media.

It is apparent that the filtering element can also be easily replaced from the curtain screen 30, and for this purpose, the lid 30a of the curtain screen 30 is shown in FIG.

Therefore, the initial excellent water containing fine contaminants less than 3 mm supplied through the cylindrical screen 20 has a filtration element attached to the carrier and the media by decreasing the flow rate due to the increase in the cross-sectional area while passing through the curtain screen 30 ( 31, the fine contaminants are excluded, and thus the initial stormwater is finally treated water with improved water quality and flows to natural or nearby waters.

It is apparent that when the curtain screen 10 is disposed in the circumference of the cylindrical screen 20, the filtration efficiency of the fine contaminants included in the initial excellent water is further improved.

The vortex 21 according to the present invention is installed in the lower portion of the cylindrical screen 20, the coarse contaminants and sediment contaminants transferred through the contaminant discharge pipe 17 and the intermediate contaminants sedimented and removed from the cylindrical screen 20 sewage treatment plant. It is used for the discharge to the sewage pipe (4) connected to.

Preferably, the vortex 21 is formed to be inclined downward so that the cyclone phenomenon of the initial superiority occurs inside the cylindrical screen 20.

That is, the initial excellent water supplied to the cylindrical screen 20 gradually rises from the bottom of the vortex 21 because the lower portion of the cylindrical screen is open, and the bottom of the vortex 21 is formed to be inclined downward, The drain hole 22 is minutely formed in the center of the bottom, so that the vortex phenomenon occurs in the process of draining the initial excellent water through the drain hole 22.

As a result, by the vortex phenomenon, the initial superiority causes the cyclone phenomenon to rise while the whirlwind gradually occurs inside the cylindrical screen 20. The cyclone phenomenon causes the centrifugal force inside the cylindrical screen 20 to generate the initial excellent internal pressure. The intermediate contaminants will flow quickly from the center of the cylindrical screen 20 to the edge.

The vortex 21 utilized for this purpose is installed in the lower portion of the cylindrical screen 20 in a state where a plurality of leg portions 23 are formed at the circumferential edges of the radial initial excellent treatment apparatus 1 according to the present invention. Or, when buried in a nearby sea area will also play a role of supporting in a floating state from the ground at the same time.

This allows the treated water to be completely removed from the contaminants can be drained to natural rivers or nearby waters.

Here, the process of the initial excellent through the radial initial excellent treatment device 1 according to the present invention as described above in detail.

As shown in FIG. 5, the initial rainwater including various contaminants of the ground in rainy weather flows into the confluence sewer pipe 2 in a first-excluded state through a known screen device 3, and the confluence sewer pipe 2 is internal. The initial excellent water is drained to the screw screen 10 in the state of the deposited sediment contaminated.

Radial initial water treatment device (1) according to the present invention so as to exclude in advance the contaminants and contaminants of the size exceeding the coarse contaminants contained in the initial excellent water supplied through the combined sewage pipe (2) in the buried area separately (5) can be installed and used.

In addition, the buried area in which the contaminant screen 5 is installed has a structure capable of separating and removing oil or grease in the initial rainwater that has passed through the contaminant screen, as shown in FIG. 5.

As such, the screw screen 10, which is supplied with the initial excellent water in which various kinds of contaminants and contaminants exceeding the coarse contaminants are pre-excluded, is removed through the screen body 11 to remove coarse contaminants and sediment contaminants of 5 mm or more. The screen 20 is drained.

The conveying screw 12 transfers the coarse contaminants excluded from the screen body 11 to the contaminant discharge pipe 17 connected to the front end discharge pipe 11a of the screen body 11, and the contaminant discharge pipe 17 is transferred. The coarse coarse matter freely falls into the vortex 21 to be discharged.

On the other hand, the initial excellent water supplied to the cylindrical screen 20 gradually rises from the bottom of the vortex 21, or when the bottom of the vortex 21 is formed to be inclined vortex phenomenon around the drain hole 22 It gradually rises as a result, and thus the cyclone phenomenon occurs in the cylindrical screen 20, and the initial excellent flow is formed from the center of the cylindrical screen 20 to the edge by the centrifugal force through the cylindrical screen 20.

In this process, the intermediate contaminants included in the initial excellent water are excluded by the cylindrical screen 20 and are discharged to the vortex 21 while being gradually settled when the initial excellent water supply is no longer made.

The initial excellent through the cylindrical screen 20 to remove intermediate contaminants of 3 mm or more is doubled by the carrier and the media to which the filtration element 31 is attached due to the decrease in flow rate due to the increase in the cross-sectional area of the curtain screen 30. Filtering excludes fine contaminants less than 3 mm.

As such, the treated water from which various contaminants are excluded through the radial initial excellent treatment device 1 according to the present invention is finally flowed into the natural river or the adjacent sea, and the contaminants contained in the initial excellent water are the bottom of the vortex 21. After discharged to the sewage pipe (4) through the drain hole formed in 22 is finally discharged to the sewage treatment plant.

On the other hand, after the initial excellent treatment is completed by washing the filtration element 31 and the like disposed on the curtain screen 30 as well as the inside of the radial initial excellent treatment device 1 according to the present invention through a spray nozzle or the like. It is to suppress the occurrence of water corruption and odor, and the wash water is discharged to the sewage treatment plant through the sewage pipe (4) because the bottom of the buried area is inclined.
