More specifically, the present invention relates to a side port for reducing non-point pollutants and an operation method thereof configured to store initial rainwater at an initial stage of rainfall and discharge and process it after the end of rainfall.

In general, water pollution sources can be divided into point sources and nonpoint sources. Among them, point source means pollutant source that is easy to collect due to the clear path of pollutant, and it is possible to predict yearly amount due to relatively little seasonal influence, so design and management of treatment facility such as treatment plant It's easy.

Non-point source is a source of pollutants washed out by rainwater during rainfall, and it is characterized by the fact that the outflow and discharge paths of pollutants are not clearly distinguished.

In the case of rainfall, the movement of the nonpoint source causes the first-flush effect, which has the highest concentration of pollutants discharged during the initial rainfall, as the particulate contaminants deposited on the surface are introduced into the stream due to the rainwater. Appears and the concentration decreases as the rainfall continues. As such, the rainfall runoff contains high concentrations of organic and various toxic substances, which may be the main causes of destruction of river ecosystems and water pollution, including fish population deaths.

Such a device for discharging rainwater outflow through sedimentation, filtration, etc. before being discharged to a river or a river is disclosed in Patent Registration No. 10-0896015.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Here, in adding reference numerals to the elements of each drawing, it should be noted that the same elements are denoted by the same reference numerals as much as possible even if they are shown in different drawings.

1 is a schematic cross-sectional view of a side opening for reducing non-point pollutants in accordance with an embodiment of the present invention.

The side opening (hereinafter, referred to as a side opening) for reducing nonpoint pollutants of the present invention stores initial rainfall effluent water (hereinafter, excellent) containing a large amount of nonpoint pollutants in the sidewall, and discharges it through sewage pipes or sewage pipes after the rainfall is finished. To be treated at the sewage treatment plant.

Side opening 10 of the present invention includes an inlet chamber (2), diaphragm (3), blocking plate (4), drain pipe (5), valve (6), overflow water outlet (7).

An inlet 1 through which rainwater flows is formed in the upper portion of the inflow chamber 2. The inlet 1 is usually connected to the storm receiver installed in the periphery of the road.

Inflow chamber 2 is provided with a diaphragm 3 for storing the initial rainfall at the beginning of the rainfall and minimizing mixing with later rainfall. Here, the initial stormwater refers to rainwater that is discharged at the beginning of the rainfall because a large amount of pollutants such as organic matter is contained, and the later stormwater spills after the initial stormwater refers to rainwater that contains relatively less pollutants. For example, since the rainfall of about 5 mm in the initial rainfall contains a large amount of pollutants, the rainfall that flows out to about 5 mm in the initial rainfall is called the initial storm, and the rainfall that flows out after about 5 mm in the initial rainfall is the rain storm. have.

Rainwater introduced through the inlet 1 is stored in the inlet chamber 2 along the diaphragm 3. The diaphragm 3 preferably has a slight inclination downward so that the initial stormwater easily enters the inlet chamber 2. Rainwater flows through the spaced space between the inlet chamber 2 wall and the diaphragm 3 and is stored in the inlet chamber 2.

The diaphragm 3 is attached at an appropriate position on the wall of the inlet chamber 2 so that the rainwater corresponding to the initial rainfall may be stored in the lower portion of the diaphragm 3 depending on the road conditions.

The blocking plate 4 is installed on the upper portion of the diaphragm 3. The blocking plate 4 is installed in the inflow chamber 2 to intersect with the diaphragm 3, so that the latter rainwater introduced into the inflow chamber 2 through the inlet 1 is stored in the inlet chamber 2. Do not fall directly on the surface of the water. Preferably, the barrier plate 4 extends a certain distance above the diaphragm 3 to help minimize the mixing of the initial storm and the latter storm. The blocking plate 4 may be installed to be slightly inclined downward.

The overflow water outlet 7 is provided at the upper portion of the inflow chamber 2. If the rainfall amount is large and the amount of rainwater flowing in is greater than the amount that can be accommodated in the inflow chamber 2, the excess rainwater is discharged through the overflow water outlet 7.

At present, sewage sewer is divided into combined and classified sewer. Combined conduit is a method of connecting sewage and rainwater to the same pipe to the sewage treatment plant. In the combined conduit, usually only sewage is sent to the sewage treatment plant, and during rainfall, only sewage and rainwater are combined, so that only the flow rate that can be transferred to the sewage treatment plant is sent to the sewage treatment plant, and the rest is overflowed and discharged into the stream. Classified conduits are a method of excluding sewage and rainwater into separate pipes. Rainwater is discharged to streams through storm drains, and sewage is treated by connecting to sewage treatment plants. Korea's conduits are mostly joined together, but recently, the share of classifications is increasing.

Since the rainwater discharged through the overflow water outlet 7 has a relatively low concentration of pollutants, the overflow water discharge port 7 is discharged to the stream in connection with the combined sewage drainage or the fractionated storm drainage.

In the lower part of the inflow chamber 2, a drain pipe 5 for discharging the stored rainwater and a valve 6 for opening and closing the drain pipe 5 are provided. The drain pipe 5 is connected with the combined sewage pipe or the sewage pipe. The valve 6 is normally closed and then opened after the end of the rainfall, preferably after 12 hours, and the rainwater stored in the inlet chamber 2 is sent to the sewage treatment plant via a combined sewage or sewage sewer for treatment. Can be. Opening and closing of the valve is done by manual or centralized transmission.

As described above, the side mouth 10 of the present invention stores the initial rainwater at the beginning of the rainfall by the diaphragm 3 in the inflow chamber 2, and then sends the wastewater to the sewage treatment plant through the drain pipe 5 after the rainfall is finished. For example, it is possible to prevent the initial rainwater with high concentration of pollutants from being discharged into the stream to contaminate the stream.

In addition, since the side opening 10 of the present invention is small in size and simple in structure and does not have a filter or the like having a complicated structure for filtering contaminants contained in rainwater, installation cost is reduced and maintenance is easy. have.

Hereinafter, a method of operating the non-point pollutant reducing side mouth according to the present invention will be described with reference to FIG. 1.

When the rainfall starts, rainwater is introduced into the inlet chamber 2 through the inlet 1 installed at the top of the side opening 10 through the rainwater receiver installed in the periphery of the road. The introduced rainwater is stored in the inflow chamber 2 along the obliquely installed diaphragm 3. As time goes by, the water level in the inlet chamber 2 rises, and the initial rainfall with high concentrations of contaminants is generally stored below the diaphragm 3. Later storms introduced after the initial storm are generally located on top of the diaphragm 3. In the inlet chamber 2 there is a diaphragm 3 and a barrier plate 4 to minimize mixing of the initial storm and the latter storm.

Excess rainwater exceeding the amount that can be stored in the inflow chamber 2 according to the rainfall is discharged to the stream through the overflow water outlet 7 in connection with the combined sewage drainage or the fractional storm drainage.

As such, the side opening 10 of the present invention stores the initial rainfall in the inlet chamber 2 so as to minimize the mixing of the initial rainfall at the beginning of the rainfall and the later rainfall at the end. After a certain period of time after the rainfall has ended, for example, after 12 hours, the valve 6, which was closing the drain pipe 5, is opened and stored in the inflow chamber 2 (including the initial storm and some later storms). ) Is discharged into a combined sewage or sewage sewer and treated at a sewage treatment plant.

The valve 6 is closed after the end of the rainfall, preferably before three days have elapsed. This is because when the clear day lasts more than 3 days after the end of the rainfall, contaminants accumulate on the road surface, so that the storage of the initial rainwater in the inflow chamber 2 should be possible.

2 is a schematic cross-sectional view of a side opening for reducing non-point pollutants according to another embodiment of the present invention.

A plurality of diaphragms 3a and 3b or blocking plates 4 may be provided in the inflow chamber 2 in the transverse direction or the longitudinal direction. In this embodiment, a plurality of diaphragms 3a and 3b are provided in the longitudinal direction. By providing a plurality of diaphragms 3a and 3b, it is possible to more easily prevent mixing of the initial rainwater and the later rainwater stored in the lower portions of the diaphragms 3a and 3b.

Figure 3 is a schematic cross-sectional view of the side port for reducing non-point pollutants in accordance with another embodiment of the present invention.

On the wall surface of the inflow chamber 2, a plurality of fasteners 8, 9 for detachably fixing the diaphragm 3 (including the blocking plate 4) are located in the longitudinal direction. Therefore, the diaphragm 3 can change the position fixed to the wall surface of the inflow chamber 2. In order to change the position where the diaphragm 3 is fixed in the inflow chamber 2, a position change is simply performed by detaching the diaphragm 3 attached to one fixture 8, and inserting it into another fixture 8, This becomes possible. This makes it possible to fix the diaphragm 3 in the most suitable position to store the initial rainwater by the diaphragm 3 depending on the situation.

Figure 4 is a schematic cross-sectional view of the side port for reducing non-point pollutants in accordance with another embodiment of the present invention.

The diaphragm 3 or the blocking plate 4 is installed so that the inclination can be adjusted suitably. In addition, the diaphragm 3 (including the blocking plate 4) is configured to be attached to the wall surface of the inflow chamber 2 so that it can be flipped vertically. This can facilitate maintenance such as cleaning the inside of the inflow chamber 2.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention will be.
