Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an eccentric type non-

The present invention relates to an eccentric nonpoint source pollution reduction device.

More specifically, it is installed horizontally on the bridge side of roads, bridges, and extended bridges, maximizes the purification of nonpoint pollution sources and pollutants from the polluted water flowing into the river during the precipitation, minimizes the damage caused by water pollution, And more particularly, to an eccentric type non-point pollution source abatement apparatus for smoothly discharging contaminated water to prevent flooding.

Generally, pollutants are pollutants such as dirty sewage, industrial wastewater, and livestock wastewater, which are discharged from point sources with limited clear point sources, and also pollutants such as agricultural lands, pastures, forests, construction sites, mines, Discharge areas, such as landfills, urban areas, roads and industrial sites, can be divided into nonpoint pollutants emitted from a wide range of nonpoint pollution sources.

Non-point pollutants are pollutants that come out along with surface runoffs when they are exposed to rain. These include fertilizers, pesticides, soil sprinkling plants, housing spills, traffic pollutants, dust and garbage in urban areas, Water, air pollutants falling on the earth's surface, and rainwater containing all pollutants are actually the main non-point pollutants.

In addition, pollutants emitted from the above-mentioned pollution sources are distributed in various forms such as heavy metals, pathogenic microorganisms, organic compounds, radioactive substances, toxic substances and other salts. Therefore, rainwater is washed away in rain, And the water pollution caused by the flowing into the public water or ground water, destruction of the ecosystem and ultimately to humans is very harmful.

Particularly, in the case of non-point pollutants, about 22-37% of pollution loads such as rivers, lakes, and other public water bodies and ground water, as well as rainwater falling during the initial rainfall, % Is a non-point pollution source, and it is the most important cause of water pollution. Therefore, it is most important that initial rainfall containing non-point pollutants is not poured into public water bodies such as rivers and lakes or ground water without purification.

Since these non-point pollutants usually flow out with a lot of rainfall, there is a large difference between daily and seasonal emissions, and it is difficult to forecast and quantify, and it has a characteristic of being influenced by weather conditions, geology, and topography which are difficult to manure. Therefore, the emission standard is not established systematically.

On the other hand, since the outflow characteristics of pollutants in the stormwater runoff described above show a relatively high pollutant concentration in the initial rainfall runoff, it is possible to treat more than 80% of the entire rainfall with the rainfall runoff capacity of about 20 mm alone Are reported.

As a result of the "Non-point Source Pollution Research Service" (conducted in June 2000) for the upper reaches of the Paldang Dam in the main water source of the Han River, which is the main water source of the residents of the metropolitan area, the total generated load (BOD standard) The pollutant loads generated from point sources such as sewage, industrial wastewater, and livestock wastewater were 130,650t / year, 80.4%, and the pollution load from nonpoint source was 19,3193t / year.

 The non-point pollutant sources were estimated to be 44.5% of the total discharge load (BOD standard), and non-point pollutants were found to have a significant impact on water pollution. Geum, Nakdong and Yeongsan It is expected to show a pattern. As a result, the proportion of nonpoint pollutant impacts on water quality is gradually increasing as regulations on point pollutants with regulatory standards are strengthened and environmental facilities are expanded.

Therefore, in the conventional non-point pollution natural purification system, a drainage channel is formed at a boundary portion connected from a slope surface to a lower roadside, and a drainage path is formed between one side wall of the drainage channel and the slope surface to smoothly discharge the flowing- A plurality of inflow holes are formed in the sidewall of the drainage line contacting with the soil layer, and the soil layer absorbs and cleans the nonpoint pollutant contained in the initial rainwater initially flowing from the slope surface, A second filter material layer having a predetermined size of gravel, a third filter material layer having a non-woven fabric, and a fourth filter material using an artificial filter material such as synthetic resin to allow the plants to be planted for discharging into the inflow hole of the filter material. And a layer including an intermediate layer.

However, the natural purification system according to the prior art can be applied only to a very limited extent due to the remarkably low efficiency, such as land acceptance for forming a sloping ground surface. Especially, when the sloping ground surface is pushed down to the soil layer, Not only the purification efficiency is reduced, but also the uncleaned stormwater is introduced through the drainage hole of the drainage channel, thereby mixing with the cleaned treatment water through the soil layer and the filter medium layer.

In addition, as the amount of rainfall increases, the number of pollutants flowing into the drainage channel overflows, and there is a fear of flooding damage, and there is a problem that the purification rate of polluted water is lowered.
