Description

Non-point pollutant treatment device {Non-Point Source Contaminant Treatment Apparatus}

The present invention relates to a non-point pollutant treatment apparatus. More specifically, the non-point pollutants contained in the effluent during the initial rainfall can be treated through several filtration processes, and the treatment efficiency of the nonpoint pollutants can be maximized. The present invention relates to a non-point pollutant treatment device that minimizes contamination of clean waterfronts and groundwater, and prevents the destruction of the ecosystem by preventing the nonpoint pollutants from penetrating into the soil.

In general, pollutants include point pollutants and agricultural lands, grasslands, forest lands, construction sites, mines, logging sites, waste disposal plants, garbage, etc. 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.

The pollutants emitted from the pollutants as described above are distributed in various forms such as heavy metals, pathogenic microorganisms, organic compounds, radioactive substances, toxic substances and other salts, and are washed with rainwater during rainy weather, such as rivers and lakes. As water flows into public waters and underground water, it causes water pollution, which in turn destroys ecosystems and ultimately damages humans.

In particular, in case of non-point pollutants, the rainwater falls during the initial rainfall, as well as about 22-37% of the pollutant loads in public waters such as rivers, lakes, and groundwater. Since% is investigated as a nonpoint source, it acts as a major factor causing water pollution. Therefore, it is most important not to send the initial rainfall containing nonpoint pollutants without purification to public waters such as rivers, lakes, or groundwater.

On the other hand, the outflow characteristics of pollutants in stormwater runoff are relatively high in the initial rainfall runoff, so it is possible to treat more than 80% of the total rainfall with a stormwater runoff capacity of about 20mm rainfall. Is being reported.
