Description

Non-point source a contaminant purification apparatus of first rain}

The present invention relates to an apparatus for purifying nonpoint pollutants in rainwater initial runoff, and more particularly, the discharge area is reduced to a concentration of nonpoint pollutants included in the initial rainwater runoff during rainfall from a wide range of nonpoint sources. It relates to a non-point pollutant purification device of the initial excellent runoff water that can be discharged.

In general, pollutants include point pollutants and agricultural lands, grasslands, forest lands, construction sites, mines, logging sites, waste disposal plants, garbage, etc., which are discharged from defined and limited point sources such as domestic sewage, industrial wastes, and livestock wastes. Discharge areas such as landfills, urban areas, roads and industrial sites can be divided into nonpoint pollutants emitted from a wide range of nonpoint sources.

Contaminants emitted from the pollutant as described above are distributed in a variety of forms such as heavy metals, pathogenic microorganisms, organic compounds, radioactive materials, toxic substances and other salts. These pollutants are usually swept away in rainy weather and flow into public waters such as rivers, bays and lakes, or underground waters, causing water pollution, and eventually destroying ecosystems. It causes great harm.

On the other hand, in the case of point pollutants having a clear discharge point among the pollutants as described above, a separate purification device or wastewater treatment facility is installed in a home, factory, or livestock farm, but the pollutant is purified to some extent. In the case of pollutants, the discharge area is not only extensive but mostly remains on the surface of the earth, and it is the main cause of water pollution by entering the public water or groundwater such as rivers, bays and lakes with rainwater during rainy weather.

In particular, in the case of non-point pollutants, as described above, the rainwater that falls during rainy weather, especially during the initial rain, flows into public waters or groundwater such as rivers, bays, and lakes. It is of utmost importance not to let it flow into public waters or underground water without purification.

As mentioned above, non-point pollutants in the pollutants are caused by flooding in the quantitative aspect of Korea and water quality deterioration in public waters due to non-point pollutant outflow during rainfall. In particular, in urban areas, as the impermeable pavement ratio increases, the peak runoff during rainfall increases, and thus the mobility of non-point pollutants increases, requiring management in terms of water quality and quantity.

In addition, the non-point source described above refers to a pollution source generated from a non-fixed source such as a factory or domestic sewage as a relative concept of a point source, and generally refers to a pollution source that flows out as rainwater during rainfall. These nonpoint sources account for 22-37% of the pollutant loads of the four rivers, and in the case of Paldang Water, 44.5% of the pollutant loads are irradiated as nonpoint sources.

On the other hand, the pollutant outflow characteristics in the stormwater runoff show relatively high pollution concentrations in the initial stormwater runoff, so that only 80% of the rainfall can be treated with the stormwater treatment facility capacity for about 20mm of rainfall. It is becoming.

Therefore, it is difficult to install rainwater treatment facilities requiring large land area due to the difficulty of land acceptance in the existing urban areas. In order to use the device-type facilities such as the rainwater pumping station and the construction of a new city, in order to prevent the drastic change in the hydrologic discharge characteristics due to the increase in the impermeability rate of the area, the ratio of the impermeability rate of the city to a certain level or the excellent before and after development Compared with changes in runoff, if there is more runoff than before development, it is recommended to install infiltration and storage facilities to control the runoff, and the waterside area is an area that can directly affect river water quality when planning land use in urban areas. Restrain water and damage, It has been reported to use a buffer zone for reducing salt substances.

In addition to the rapid introduction of storm water runoff treatment facilities as described above, periodical city cleaning, inspection and cleaning of manholes and storm drainage facilities before the rainy season, dredging of sediment at the bottom of the reservoir, installation of storm drains in construction areas, etc. The plan to remove various nonpoint sources scattered in urban areas is also under consideration.

However, despite the various measures to treat the initial excellent runoff as described above, it is actually difficult because there are too many limiting factors such as difficulties due to land acceptance.

The present invention was devised to solve the problems described above, and cleans the non-point pollutants introduced with rainwater during rainy weather, especially during rainy weather, through various steps, such as public waters such as rivers, bays, lakes, and groundwater. It is an object of the present invention to provide a non-point pollutant purification device for initial excellent effluent that can prevent water pollution.

Furthermore, another object of the present invention is to purify the non-point pollutants contained in the initial rainwater runoff during rainy weather and to protect the natural ecosystem through prevention of water pollution caused by the non-point pollutants by flowing them to public water or groundwater. Of course, to reduce the harm to the end-user humans.
