Description

Collection-type non-point pollution reduction device {CONTAMINANT PURIFICATION APPARATUS OF NON-POINT SOURCESBY THE EARLY-STAGE STORM RUNOFF}

The present invention relates to a catchment type non-point pollution reduction device. In particular, the catchment type non-point pollution reduction that purifies pollutants of rivers by filtering pollutants accumulated on the ground in unspecified areas such as urban areas, construction sites, and general roads Relates to a device.

Generally, on the road surface, in addition to the particulates contained in the exhaust gas emitted by the driving of automobiles, especially diesel engine cars, the dust from the friction between asphalt and tires, the smoke and dust of factories, etc. After the rain, the pollutants flow into the sewer manhole at the same time, and the polluted water and pollutants flow into the sewage in various directions and flow into the final large river.

In particular, inside the sewer manhole, the contaminant is filtered by filtering the contaminated water contained in the sewage, and only the remaining treated contaminated water flows to the stream. Looking at the prior art data on the manhole of the sewer as described in the Korean Patent Registration No. 0869140, the chamber cover is formed on the top of the chamber and the through hole for allowing contaminated water to pass through, and the contamination disposed inside the chamber and introduced into the chamber. It consists of a filter bag for filtering contaminants from the water and a fixing device for fixing the filter bag to the chamber. When the contaminated water flows into the chamber cover, the contaminated water is filtered by the filter bag to filter the contaminants contained in the contaminated water. And the filtered contaminated water is discharged to an outlet.

However, in the above, the function of the chamber cover is to filter large contaminants contained in the contaminated water, where small contaminants passed through without filtering are collected in the filter bag at a second time. In case of rain, secondary pollutants are instantly accumulated by the filter bag, and even if the upper fixing device and the lower filter support are installed, the filter bag does not overcome the weight of the pollutant and has a defect.

The present invention has been made to solve the above problems, the purpose of the contaminants having large particles of cigarette butts, leaves, or other garbage is filtered as before in the first screen formed in the manhole, relatively small particles Soil or suspended matter is filtered through a second screen formed in the collecting section, so that only the final particulate contaminants are collected in the filtration filter.

Still another object is to provide that the entire filter cloth is accommodated inside the filter frame, thereby preventing the filter cloth from being damaged by the weight of the contaminants in advance.

The present invention for achieving the above object is a locking jaw formed so that the manhole (M) having the primary screen 12 is seated on the inlet 11 and the inlet 11 edge in which the contaminated water generated by the non-point source is introduced In the water collecting filtration type non-point pollution reducing device, comprising: a chamber 10 including a discharge port 14 through which a filtered treatment water is discharged;

A collecting part 20 for collecting contaminated water into one place on the chamber 10;

A lower portion of the water collecting portion 20 and a filtering portion 30 for discharging only the treated water filtered through the contaminated water; It is achieved by consisting of a filter support portion 40 for supporting the filter portion 30 at the bottom.

The present invention filters the soil or suspended matter, which are relatively small particles, with the second screen formed in the collecting section and collects only the final particulate contaminants in the filtration filter. Thus, when the contaminated treated water is further purified and drained into the river, the filtration frame is particularly filtered. Since the whole is wrapped, it is effective to prevent damage caused by overweight of the filtration filter.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

First, as illustrated in FIGS. 1 and 2, the inlet 11 into which the contaminated water generated by the non-point source is introduced, and the inlet 11 have a plurality of inlet holes 12a and screen bars 12b at the edges thereof. It may be composed of a chamber 10 including a locking projection 13 formed so that the manhole M including the car screen 12 can be seated, and a discharge port 14 through which the filtered treated water is discharged.

Between the manhole M and the locking jaw 13, the collecting panel 21 of the upper part of the collecting part 20 is seated, and the collecting panel 21 has an inclined surface 21a and a chamber for collecting contaminated water in one place. 10) formed by a handle 21b for detaching the water collecting panel 21 to inspect the inside, and the lower part integral with the water collecting panel 21 is provided with soil or floating particles, which are relatively small particles contained in contaminated water. The second screen 22 has a plurality of outlet holes 22a and a screen bar 22b for filtering.

The lower edge of the second screen 22 is seated on the catching jaw 31a of the upper end of the filtration frame 31 in the filtration unit 30, and the filtration filter formed of a unitary body 32 inside the filtration frame 31. (33) The upper part is inserted.

Here, the unit assembly 32 may be one of a method of sewing and a method of attaching with an adsorbent.

The filtration frame 31 is formed with a plurality of filtration holes (31b) for discharging the treated water treated with contaminants to the discharge port (14).

Here, it is preferable that the filtration hole 31b is perforated over the whole and bottom surfaces of the filtration frame 31. As shown in FIG.

Here, the filtration frame 31 may be one of circular or square or rectangular.

The filter support part 40 supporting the filtration frame 31 at the bottom is disposed, but the space support member 41 protrudes from the center of the filter support part 40 so that the contaminated water filtered by the filtration part 30 is filtered. (31) The movement path S is formed so that it may move below.

And the separation prevention member 42 which protrudes from the four corners of the filter support part 40 so that the filtration frame 31 cannot move is protruded.

The operation of the present invention configured as described above is as follows.

Contaminated water generated by nonpoint pollution flows into the manhole (M). At this time, contaminants having large particles of cigarette butts or leaves or other garbage in the contaminated water are filtered out of the primary screen 12.

The first filtered contaminated water moves along the inclined surface 21a of the collecting panel 21 of the collecting unit 20 and naturally flows into the filtration filter 33 of the filtering unit 30.

The contaminated water introduced into the filtration filter 33 is discharged from the contaminated water treated by the discharge port 14 via the filtration filter 33. At this time, the filtration filter 33 collects small particles in the contaminated water.

As shown in FIG. 2, the contaminated water introduced by the initial rainfall is discharged as the contaminated water treated by the filtration holes 31b having a height of (L) and discharged beyond the capacity of the filtration filter 33 due to the continuous rainfall. When the contaminated water flows in, the filtration filter 33 is filled so that the contaminated water according to the late rainwater overflows to the outlet hole 22a of the second screen 22 formed at the height of (H), and thus the bottom surface of the chamber 10. Falling to and drained to the discharge port 14 along the movement path (S).

In the above, even when the contaminated water overflows into the outflow hole 22a, the soil and suspended matter, which are small particles remaining in the contaminated water, are filtered out.

On the other hand, even if the filtration filter 33 is filled with contaminants to increase the weight, the filtration filter 33 is not damaged by the external filtration frame 31, and the separation prevention member disposed below the filtration frame 31. By 42 the filter frame 31 is always in place.

In addition, when contaminants contained in the contaminated water are collected by the rainy season as described above, a predetermined period of time is selected to separate the manhole M from the inlet 11 and using the handle 21b of the water collecting panel 21 to collect the water collecting panel.
