The present invention relates to an initial rainwater treatment device using carbides, a feature of the present invention is to quickly treat rainwater (falling rain) early in rainy weather to prevent pollution of river water, thereby maintaining the ecosystem order .

In general, if the pollutants flowing into the public water are largely divided, they can be classified into regular point source pollutants and irregularly generated non-point source pollutants.

In the past, Korea's water quality management has implemented measures to reduce point source pollutants that occur relatively regularly such as domestic wastewater and factory wastewater.

This reduction measure is mainly because the discharge characteristics of point sources, such as domestic sewage and factory wastewater, which are generated on a regular basis, are continuously generated at a certain point, so there is almost no difference in emissions due to rainfall or rain.

However, non-point source pollutants are pollutants that are distributed in a relatively large area, compared to the above point sources, and lower air pollution in forests, grassland, urban land, construction sites, agricultural land, river sediments, roads and roofs. Including contaminants such as water, such contaminants are suddenly released during rainfall, so the change is relatively large between daily and seasonal, so it is very difficult to predict and regular quantification is difficult.

In particular, rainfall is irregular and unstable depending on the weather, so the road surface, surrounding conditions, the number of days ahead, traffic conditions, etc. Due to the influence of various factors, it contains a lot of indeterminate factors (不 確定 要 일정) has a characteristic that is difficult to identify the property uniformly.

Conventionally, non-point pollutants spilled out with rainfall are difficult to collect and flow into rivers without special treatment, contaminating river water quality, thereby destroying the water ecosystem.

In addition, the amount of nonpoint pollutant that enters rivers and small lakes by mixing with sudden rain or snow melt is closely related to rainfall conditions and regional characteristics such as rainfall and pre-drying days. For example, treatment through uniformly large-scale treatment plants, such as point sources, is very difficult and inefficient.

As the water impermeability (blocking of rainwater, such as concrete or asphalt, etc.) increases in recent years, the amount of rainwater is not absorbed into the soil during rainfall and increases in the amount of water, which increases the risk of flooding and decreases the amount of groundwater. It is a factor that usually causes dry weather of rivers.

In addition, floating materials such as earth and sand, nutrients such as nitrogen and phosphorus, and high concentrations of heavy metals are not processed, and the fish enters rivers and destroys habitats such as benthic organisms that die in groups or inhabit the bottom layer. Serious problems, such as to cause.

In order to solve these shortcomings, measures should be taken to manage point sources such as wastewater treatment facilities and sewage treatment facilities, while at the same time, measures should be taken to reduce nonpoint pollutants from the stage of land development planning.

Therefore, the present invention has been made to improve the above problems, the present invention is a device for treating the non-point source of pollution caused by the initial rainfall, can be installed immediately in the existing storm water, especially soil, stone, leaves, such as Coarse contaminants are treated first, and fine contaminants such as sand and mud are removed by rotational centrifugal force through rainwater port provided eccentrically and unilaterally, and then processed through a carbide fibrous filter using sewage sludge. It can be extended to a further, and on the other hand, it is possible to selectively process only the initial rainfall of high concentration by the amount of change in the flow rate, and in particular to increase the efficiency of the filtration by providing two stages of filtration to increase the treatment efficiency, the filtration To measure the replacement cycle due to the blockage of 1.2 filter medium, carbide embedded in the With the differential pressure part in the center, it is possible to know when to replace the filter media due to the differential pressure generated in the 1.2 primary filtration part, which makes it possible to treat the stable initial rainfall very efficiently.

Hereinafter, the structural features for achieving the above object of the present invention will be described with the accompanying drawings.

In the present invention, the rainwater can be moved to the road surface 19, the rainwater can be moved to a certain standard is provided, the rainwater drainage (12) in the rainwater inlet (11) and the manhole (10) is installed at regular intervals In structure,

At the bottom of the rainwater inlet 11 of the rainwater conduit 12 is provided with a contaminant treatment tank 13 as a structure, on the side to provide a rainwater movement port 16 to be eccentrically to the side, Install a rectifying wall 15 to block the movement of foreign matter.

In the lower portion of the manhole 10 next to the contaminant treatment tank 13, the cone portion 17 and the backflow prevention plate 18 is provided with a sediment storage unit 14 provided at the lower end, and the sediment storage unit 14 The upper part of the filter 20 is provided with a filter unit in two stages.

The structure of the filter 20 is formed inside the filter case 21 having a substantially cylindrical shape, and having a differential pressure portion 23 through two filter nets 22 in the center, and having a filter material having different particle sizes of carbides at the upper and lower sides. One primary filter part 24 and a secondary filter part 25 are provided.

The differential pressure portion 23 provided between the filter net 22 is connected to the pressure gauge pipe 26 and connected to the micrometer 28 separately provided in the upper manhole 10 to the primary filtration portion 24 and 2. Lifting ring (27) to be able to identify the difference in the pressure generated in the charging portion 25 from the outside, and to help the lifting during the repair and replacement of the filter material on the filter case 21 (27) ).

The backflow prevention plate 18 and the cone portion 17 is configured to prevent the phenomenon that the relatively large foreign matter once moved to the deposit storage portion 14 is randomly introduced into the filter 20 side by the excellent vortex phenomenon, It is obvious that this should be designed in consideration of cleaning, and other components can be arbitrarily changed in design such as specifications or shapes to meet the functions thereof.

The present invention, which can be configured as described above, is a device for treating a nonpoint source of pollution caused by an initial rainfall, and can be immediately installed in an existing storm conduit 12, particularly, a coarse contaminant such as soil, stone, and leaves. Priority treatment in the treatment tank 13, the fine contaminants such as sand or mud is installed in the bottom by moving to the sediment storage unit 14 by the rotational centrifugal force through the rainwater moving port 16 provided eccentrically with one side After the backflow is prevented through the backflow prevention plate 18 and the cone part 17, the fine sludge is treated by passing through the fibrous filtrate of carbide with rainwater, which can further extend the service life of the filter material. On the other hand, it is possible to selectively treat only high initial rainfall by the change in flow rate, and in particular, to increase the treatment efficiency, Compared to the increase of the efficiency of filtration and to easily check from the outside by placing the differential pressure portion 23 in the center to measure the replacement cycle due to the clogging of the 1.2 filter medium, which is a carbide embedded in the filtration unit due to the occurrence of overload It can prevent life shortening.

Hereinafter, a process and an operation according to the above-described configuration of the present invention will be described with reference to the accompanying drawings.

The present invention is usually constructed in the state as shown in FIG. 2, and once it rains, the initial rainwater flows while sweeping water including the pollutant on the road surface as shown in FIG. 3 and flows through the rainwater inlet 11. do.

At this time, the rainwater falling in the early stage contains a large amount of pollutants on the road surface. This phenomenon includes a large amount of contaminants only at the beginning, and the greater the amount of rainwater, the less pollutants thereafter. It is very important to do.

As described above, in the same state as in FIG. 3, when rainwater containing a large number of pollutants initially flows through the rainwater conduit 12 through the rainwater inlet 11, coarse contaminants such as soil, stones, and leaves are treated as a contaminant treatment tank ( 13) is treated while sinking preferentially by its own weight, and fine contaminants such as sand or mud are formed with lateral sediment storage unit while generating instantaneous rotational centrifugal force through rainwater movement holes 16 provided eccentrically with one side. 14).

Even if a small amount of initial rainwater including a contaminant is moved to the storm drain 16, or even a large amount of stormwater moves, the storm drain may not move directly toward the storm drain 12 without being purified. The upper portion of the 16 is provided with a rectifying wall (15) can prevent the phenomenon of passing immediately to the storm conduit (12).

Since the cone portion 17 and the non-return plate 18 are inclined at the lower end side of the sediment storage unit 14, fine contaminants such as sand or mud having a specific gravity sink to the bottom of the sediment storage unit 14. do.

This phenomenon causes a vortex phenomenon while the rainwater including the pollutant moving in the contaminant treatment tank 13 passes through the rainwater port 16 eccentrically to one side, and despite this vortex phenomenon, 17) and the reverse flow prevention plate 18 once settles down as it is.

Fine suspended matter having little specific gravity remaining after being precipitated in the contaminant treatment tank 13 is moved through the filter 20 installed in the upper part to the storm conduit 12 due to the continuous inflow of rainwater.

The filter 20 passes through the primary filtration part 24 and the secondary filtration part 25 in which a filter medium of upper and lower carbide is interposed by a double filter net 22 in the inner center of the filter case 21 having a cylindrical shape. .

The primary filtration part 24 and the secondary filtration part 25 are provided with a differential pressure part 23 by the filter network 22 installed in two stages, so that the rainwater introduced while the constant pressure difference occurs is moved upward.

The rainwater that has moved to the top is first filtered in the sediment treatment tank 13 and the second is filtered in the sediment storage unit 14, and the rainwater containing fine suspended matter is first and second filter part 24 and the second filter part ( 25) because only the rainwater in a clean state with little foreign matter is moved through the storm conduit 12, the rainwater discharged finally prevents the phenomenon of polluting the river or destroying the natural ecosystem.

In the present invention, since the process of transporting the contaminant remaining on the road surface 19 during rainfall in the early stage of the process is carried out, the rainwater is discharged through the storm conduit 12 so that there is almost no contaminant.

As described above, when the rainwater filter including the fine suspended matter remaining in the sediment storage unit 14 passes through the filter 20, the two-stage filter medium uses a filter medium made of carbide using sewage sludge. As the filter medium having different upper and lower particle sizes, a relatively large floating material is applied to the primary filtration part 24 and a very fine floating material is applied to the secondary filtration part 25, so that between the primary filtration part 24 and the secondary filtration part 25. In the differential pressure portion 23 provided in the pressure difference occurs.

When a difference occurs in the pressure generated by the differential pressure unit 23, its signal is displayed on the micrometer 28 connected thereto through the pressure gauge pipe 26 to check the difference in pressure from the outside, thereby checking the internal primary filter unit ( 24) and when to replace the filter medium of the secondary filter 25 can be confirmed.

As such, when the pressure signal generated by the differential pressure unit 23 confirms the replacement signal of the filter medium in the micrometer 28, the entire filter 20 is opened using the lifting ring 27 while the manhole 10 is opened. Separation from the sediment storage unit 14 to open the top, and then replace the filter medium, which is the carbide embedded in the primary filter part 24 and the secondary filter part 25 inside the filter case 21 may be installed again.

The present invention treats the various pollutants contained in the rainwater that initially falls as described above, and when it rains continuously or if it rains a lot at a time, the limited amount as shown in FIG. Because the rainwater is almost in the state of being treated, the condensate treatment tank 13 or the sediment storage unit 14 does not go through the filter 20 but immediately goes beyond the rectifying wall 15 to the storm conduit 12 for final discharge. do.

That is, since the rainwater falling at the beginning of rainy weather contains a large amount of pollutants such as foreign matter, the initial rainwater is excellent as it is quickly purified by the filter 20 of the contaminant treatment tank 13 and the sediment storage unit 14 as described above. When discharged to conduit (12), and subsequently falling down or a large amount of rain at once, further processing is required because the road surface (19) has already been cleaned by the first rain and the pollutants such as foreign substances have been washed down. As a result, only a few rainwater is treated as described above, and the remainder is moved through the stormwater conduit 12 immediately beyond the rectifying wall 15 as shown in FIG. 4 to be discharged into the stream to destroy the ecosystem or pollute the river. It is possible to prevent the end of the waste.

As described above, the present invention is a device for treating a nonpoint source of pollution caused by an initial rainfall, and can be immediately installed in an existing storm conduit 12, and particularly, a coarse contaminant such as soil, stones, and leaves is a contaminant treatment tank ( 13) is treated preferentially, the fine contaminants such as sand or mud is moved to the sediment storage unit 14 by the rotational centrifugal force through the rainwater movement port 16 provided to be eccentric with one side and the rainwater flow prevention plate installed at the bottom (18) and the concave portion (17) to prevent the backflow and settled in the lower part after removing the very fine sludge through the fibrous filtrate of carbide with rainwater can further extend the service life of the filter medium, on the other hand It is possible to selectively process only the initial rainfall of high concentration by the amount of change in flow rate, and in particular, it is provided with two stages of filtration to increase the treatment efficiency. To increase the efficiency of filtration and to check the replacement cycle due to clogging of the 1.2 filter medium, which is a carbide embedded in the filtration unit, it is possible to easily check from the outside by placing the differential pressure part 23 at the center. It is an invention of which the expected value is very excellent because it can prevent the shortening of life.
