In general, nonpoint source refers to a source that emits unspecified water pollutants at an unspecified place as a city, road, farmland, mountainous area, or construction site. On the other hand, point source refers to the source of pollutant that is easy to collect because the pollutant flow path is clear, and it is possible to predict the yearly amount due to the relatively small seasonal influence, so it is possible to design and manage treatment facilities such as treatment plants. On the other hand, non-point source is difficult to collect due to the inflow and discharge paths of pollutants, and it is difficult to collect, and the design and maintenance of treatment facilities is difficult because the amount of generation is highly dependent on weather conditions such as precipitation. There is a difficult problem.

In addition, the non-point source is a fertilizer and pesticides remaining in the farmland without being absorbed by crops, manure that is grazed on pasture, untreated livestock waste discharged from livestock farms, air pollutants mixed with rainwater, road surface sediment, etc. In case of rainfall, it flows down to the river with rainwater.

The nonpoint source is specifically classified into soil, nutrients, bacteria and viruses, which will be described in detail below.

The sediment is adsorbed by nutrients, metals, hydrocarbons, and other contaminants, and moves together, and is a contaminant that occupies a large part of rainfall runoff, causing aquatic life photosynthesis, respiration, growth, and reproduction. Affect

Nutrients are fertilizer residues, which are often spilled by rainwater to promote algae growth and worsen the quality of river water, and are flowed into the rivers by flowing out of lawns, farmlands, urban roads and sewers in houses and golf courses. . In addition, bacteria and viruses (Bacteria & Viruses) are detected in the discharge of excess from the animal waste and sewage, and in the United States there are cases where the stream is contaminated by the high concentration of bacteria and viruses contained in rainfall runoff.

Oil and grease can be fatal to aquatic organisms in small amounts, and contamination occurs during accidents such as leaks or rollovers, vehicle cleaning, and dumping of waste. Heavy metals such as lead, zinc, cadmium, copper, and nickel are commonly detected in rainfall runoff in urban areas, and over 50% of the total amount of metals flowing into rivers is discharged through soil, and it is fatal to aquatic ecosystems. Special care is required as this occurs and there is a possibility of drinking water contamination.

Organics are discharged from a wide range of places such as fields, rice fields, forests, and residential areas. Especially, in confluence, organic matters contained in the sewage that flows through the sewage pipes at low flow rates are usually deposited at the bottom of the conduit. In industrial areas, artificial organic compounds such as adhesives, cleaning agents, and solvents are widely used, resulting in improper storage and disposal. Insecticides such as herbicides, pesticides, and antifungal agents can accumulate in aquatic organisms such as plankton, causing bioconcentration through the food web, which can be fatal to fish and algae.

Gross Pollutants refers to heavy metals, pesticides, bacteria, etc. from garbage, remnants, and suspended solids generated at construction sites and worksites. Bacteria, viruses, etc. It is a carrier for rivers and reduces dissolved oxygen, causing fish to die.

These nonpoint sources listed above have a problem that the water flows into the river without any special treatment with rainfall, thereby polluting the water quality, causing fish to collectively die or destroy the habitats of benthic organisms, causing disturbance of the aquatic ecosystem.

Moreover, the recent increase in impermeable layers caused by land development increases the amount of rainwater that is not absorbed or evaporated into the soil during rainfall, increasing the risk of flooding and reducing the groundwater replenishment. It can also be a trigger.

In particular, in the case of non-point pollution in urban areas, the area of green and permeable layers is decreasing in urban areas, and the area of impermeable layers is increasing instead due to the development of residential lands, and due to the increase in traffic volume, population expansion, etc. The pollutants that have been adsorbed on the back descend during the rainy season, and they do not pass through the water impermeable surface and flow like rainwater at once. While the risk of flooding is increasing, there is a problem that the river becomes dry stream due to lack of river maintenance water during the dry season.

In addition, residential districts, roads, etc. generally emit not only suspended solids (SS) and nutrients but also bacteria and metals and some organic toxic substances.

On the other hand, when looking at the movement of the non-point source in rainy weather, the first-flush effect has the highest concentration of pollutants emitted during the initial rainfall as the particulate pollutants deposited on the surface of the surface are swept away by rainwater ) And concentration decreases as rainfall continues. That is, rainfall runoff contains high concentrations of organic and various toxic substances, which can be the main cause of destruction of river ecosystems such as fish population death and water pollution.

As mentioned above, the problem of the treatment of nonpoint source is newly emerging as a necessity for environmental protection. The present invention focuses on the management of initial rainfall runoff in order to block the inflow of nonpoint source. It is an object of the present invention to provide an initial excellent non-point pollutant treatment facility that blocks inflow of rivers.

The overall structure of the salt treatment facility.

As shown in the figure, the present invention is a non-point pollutant treatment facility of the initial excellent excellently divided into the first filtration chamber 100, the second filtration chamber 200 and the third filtration chamber 300.

The first filtration chamber 100, the second filtration chamber 200, and the third filtration chamber 300 separate and filter the contaminants of the initial downpour during rain as part of a continuous channel.

The first filtration chamber 100 is the first sump can be introduced by the initial flow of rainwater during rain. It is mainly formed to filter large particles of sand, gravel, and floats. For this purpose, the first filtration chamber 100 is divided into two parts by a structure.

As shown in FIG. 1, the structure for dividing the first filtration chamber 100 into two parts includes a partition 10-1 and a wedge screen 10-2 positioned in the center of the first filtration chamber 100. .

The wedge screen 10-2 is a curved inclined plate having a drainage hole 130 formed at the bottom as shown in FIG. 2, and the surface of the curved inclined plate is formed such that a bar having a triangular cross section forms a small gap like a floor board. Arranged screen plate (The filter plate mainly filtering large particles of suspended matter is called a screen, and the chamber on which the screen is formed is also called a screen focusing on its function. In the present invention, the wedge in the first filtration chamber 100 is also used.) The chamber space formed by the screen 10-2 will be referred to as a screen).

As shown in FIG. 1, the space is divided into two parts based on the wedge screen 10-2 by the structure of the first filtration chamber 100, hereinafter as a chamber in which the drip inlet 20 is formed. The space divided by 10-1) will be referred to as the inlet chamber 110, and the space where the wedge screen 10-2 is formed will be referred to as the screen 120.

When the first downpour flows into the inflow chamber 110 through the downflow inlet 20, the incoming downflow is collected in the inflow chamber 110, and when the water level rises, the wall 10-1 overflows the wedge screen ( Flowing down the curved inclined plate of 10-2 falls into the gap formed in the wedge screen 10-2, the dropped water is dropped into the second filtration chamber 200 through the drain hole 130 formed in the bottom.

At this time, when looking at the flow of water, heavy sediment such as sand or gravel is precipitated in the inlet chamber 110 by the monthly flow, which is a moving method in the inlet chamber 110, and the light floating material such as the fallen leaves of the wedge screen 10-2. Collected in the screen 120 without exiting the narrow gap, water is relatively large particles are filtered in the first filtration chamber 100 and moved to the second filtration chamber 200 as described above.

On the other hand, the screen space is preferably separated by a height difference between the space in which the float is collected and the wedge screen 10-2 so that the wedge screen 10-2 is not blocked by the float. Do.

As shown in FIG. 3, the second filtration chamber 200 of the present invention is a water collecting space that is formed at the bottom of the first filtration chamber 100 and collects water that is drained from the first filtration chamber 100. It is also a buffer chamber connecting the first filtration chamber 100 and the third filtration chamber 300.

The inclined drainage plate 210 divides the water channel continuous with the third filtration chamber 300 as the inclined drain plate 210. The inclined drainage plate 210 is an inclined plate that separates the continuous second filtration chamber 200 and the third filtration chamber 300. When the angle of the inclined drain plate 210 is formed as shown in FIG. 3A, the upper layer water is guided to flow before the lower water by the inclination angle of the inclined plate so that the precipitate is filtered first, as shown in FIG. 3B. When the angle of) is formed, the lower water is guided to flow before the upper water by the inclination angle of the inclined plate so that the suspended matter is filtered first.

That is, the inclined drain plate 210 to adjust the desired drainage depth according to the inclination angle, as in the embodiment shown in Figures 3a and 3b inclined plate according to the desired design purpose of the floating first filtration or the precipitate first filtration. It is possible to determine the angle of, according to this principle is to include all the concepts for representing the technical idea of the present invention, such as using a continuous inclined pipe instead of the inclined plate.

In the second filtration chamber 200, since the water below the water flows into the third filtration chamber 300 by the inclined drain plate 210, fine suspended matter such as oil flowing from the first filtration chamber 100 may be formed in the second filtration chamber 200. Filtration is carried out in the state of floating on the water surface of the filtration chamber 200.

As shown in FIGS. 3 and 4, the third filtration chamber 300 of the present invention is a continuous channel communicating with the second filtration chamber 200 and the inclined drainage plate 210. It blocks the relatively small particles flowing through the first filtration chamber 100 and the second filtration chamber 200 directly to the filter plate 310.

Therefore, the water in the third filtration chamber 300 is discharged after being filtered through the filter plate 310, the filter plate 310 is a plate-shaped in the center of the window-shaped frame 312, the filter membrane 311 is formed Structure.

The filter plate 310 in the present invention should be formed to obtain the maximum filtration efficiency with respect to the flow direction of the water.

Accordingly, the present invention proposes a deep basic structure that arranges the plurality of filter plates 310 in series as shown in FIG. 3B to allow the flowing water to be deeply filtered several times.

On the other hand, good filtration capacity is also important in the matters to be considered in the filtration of initial rainwater, but fast drainage is also an important consideration in order to prevent flooding due to rainfall.

Therefore, in the present invention, in order to improve the filtration efficiency while realizing rapid drainage, as shown in FIGS. 3A and 4, the filter plate 310 is parallel to the flow direction of the water (column crosswise with respect to the flow direction of the water). The arranging structure is also presented. In detail, as illustrated in FIG. 4, the plurality of filter plates 310 of the third filtration chamber 300 are arranged in parallel with respect to the flow direction of the flowing water, but one side of the filtration membrane is one across the joint wall 320. The other side is connected to the joint wall 320 one by one across the filtration membrane that is not connected from the one side, to form a maximum filtration area with respect to the flow direction of the flow of water, the third filtration chamber 300 by this structure ) All the channel space is used as the filtration space.

On the other hand, the filter plate 310 is convenient to manage, such as cleaning should be inserted and detached structure on the joint wall 320. Therefore, the present invention forms a guide groove 321 in which the side frame 312 of the filtration membrane 311 is slid to the joint wall 320 in a straight line.

Hereinafter, the filter plate 310 will be described in detail. The filter plate 310 is formed with a filtration membrane 311 that performs a filtration function in the middle of the window-shaped frame 312. (In the description of the present invention, the filtration membrane ( 311), the expression 'membrane' is used, but as described below, it is merely named with a focus on the filtration function and is not limited to the actual membrane.)

The filter membrane 311 portion of the filter plate 310 may be a variety of structures for realizing the filtration. In the description of the present invention, examples of the particulate filter media and the fibrous filter media, which are representative filter media, will be described.

When the filter membrane 311 is formed of the particulate filter material, a filling structure for filling the particulate filter material should be formed in the frame 312.

In the present invention, as shown in Figure 5a by forming a plate-shaped filter cylinder by overlapping the porous plate on both sides of the rectangular frame 312 of the filtration membrane to realize the filling structure, the particulate filter material filled in the filter cylinder is Schiropol particles Was used.

On the other hand, the filter plate 310 is preferably because the filtration capacity is to be adjusted according to the required purpose, in the present invention, by adjusting the schiropol particles filled in the filter cylinder from above by controlling the pores to control the filtration capacity.

To this end, the present invention is formed by the upper and lower double lid of the frame 312 of the filter barrel as shown in Figure 5, through the screw 316 by forming a screw thread on the upper lid 313 of the double lid The combined length adjusting part 315 is formed so that the lower lid 314 has a separation distance formed by the length of the screw.

That is, the upper lid 313 is screwed to the screw, the lower lid to form a through-hole through the screw, the through screw portion is coupled to the lower lid 314 with a washer or nut to the length The adjusting unit 315 will be formed, and the structure of the length adjusting unit 315 is merely an exemplary structure, but is not necessarily limited thereto.

On the other hand, in order to smoothly move up and down by the adjustment of the length adjustment unit 315, the lower lid 314 as shown in Figure 6 to form sliding projections (314-1) at both ends and both sides of the filter barrel A sliding groove 312-1 through which the sliding protrusion 314-1 is guided is formed in a frame.

When the filter membrane 311 part of the filter plate 310 is a fibrous filter material, as shown in FIG. 5B, the filter membrane 311 is formed of a fiber filter material that extends up and down the window frame 312.

Also in the fibrous filter medium, the filtration membrane 311 is formed in the upper and lower double frame of the frame 312, the upper frame 312 is formed by the length adjusting portion 315 through which the screw through the lower frame A sliding groove to adjust the separation distance to the lower frame, and to combine the fiber filter medium in the lower frame to form a sliding projection (314-1) at both ends and to guide the sliding projection (314-1) to the side frame (312) ( 312-1), it is possible to control the air gap of the fiber filter medium by the adjustment of the length adjuster (315).

In addition, at least one horizontal bar 330 is formed at the center of the side frame 312 in the filtration membrane 311 so that the fiber filter medium is supported. Because the present invention is formed in the channel with the flow of running water, even if the fiber filter medium is inflated with sufficient tension, the desired voids are not formed due to problems such as splitting and expansion of the fiber by the power of running water. Since it is not possible to rely on the fiber in the horizontal bar as described above is to compensate for the tension of the fiber filter medium.

The method for supporting the fiber filter medium in the horizontal bar 330 may be a variety of embodiments, such as a bilateral compression type bar method for compressing the fiber filter medium to the horizontal bar from both sides of the fiber filter medium, one side bar system zigzag between the horizontal bar formed the fiber filter medium.

The present invention described above is a filtration apparatus for purifying the contaminants contained in the initial rainwater, as described above, the matters to be considered in the initial rainwater filtration are also important, but the rapid drainage is also an important consideration.

In addition, the need for the apparatus of the present invention also eliminates the contaminants contained in the initial rainwater, so that it is not necessary to operate the apparatus of the present invention in the continuous rain state beyond the range of the initial rainwater polluting the stream.

Therefore, the non-point pollutant treatment facility of the initial excellent rainwater of the present invention is drained immediately without going through the non-point pollutant treatment facility of the initial excellent in the case of rain that has passed a certain rainfall.

To this end, the present invention forms a bypass channel 400 directly connected to the drain channel of the initial excellent non-point pollutant treatment facility outside the downfall inlet 20, as shown in Figure 7 and the bypass channel 400 ) To open and close the door 40 to be opened and closed depending on the weather conditions.

The opening and closing door 40 detects the level of water formed in the second filtration chamber 200 or the third filtration chamber 300 of the non-point pollutant treatment facility of the initial excellent to determine whether the rain conditions are satisfied. The water level detection buoy 220 is installed in the second filtration chamber 200 or the third filtration chamber 300, and the opening and closing door 40 of the bypass channel 400 is formed to be opened and closed by the water level detection buoy. do.

The opening and closing door 40 is preferably formed as a reverse side of the flow of water in order to prevent the reverse flow due to flooding downstream of the drainage channel.

As a simple example of this, as shown in FIG. 7, the opening and closing door 40 is installed as a revolving door 43 that is rotated by a hinge 45 on the bypass channel 400, and the contact with the revolving door 43 is performed. A stopper 42 is formed on the sidewall of the waterway side to prevent the opening of the revolving door (backflow prevention) on the storm water inlet side of the bypass channel 400, and to the storm water outlet sidewall of the bypass channel 400. It may be mentioned to form the clamp 41 is driven by the water level detection buoy 220.

According to this, during the initial rain, the opening and closing door 40 is closed so that the initial rainwater is guided to the inlet 20 of the present invention to filter the non-point contaminants included in the initial rainwater, and the initial rainfall of the present invention is the initial rainwater of the present invention. Since the internal water level of the non-point pollutant treatment facility is increased, the opening and closing door is opened, so that the downpour is directly drained through the bypass channel 400, and even if the rainfall is serious, the reverse displacement characteristic of the opening and closing door 40 is caused. Because of this, the backflow of water is blocked.

Embodiments shown for the purpose of the present invention described above are only one embodiment in which the present invention is embodied, and as shown in the drawings, it can be seen that various forms of combinations are possible to realize the gist of the present invention.

Therefore, the present invention is not limited to the above-described embodiments, and various changes can be made by any person having ordinary skill in the art without departing from the gist of the present invention as claimed in the following claims. It will be said that the technical spirit of this invention is to the extent possible.
