The present invention relates to an initial excellent purification treatment apparatus, and more particularly to an initial excellent purification treatment apparatus having an improved structure.

At present, global water shortage is a major issue in many countries, and Korea has also been unable to neglect it. In order to solve this water shortage, we have found ways to efficiently manage, secure and utilize water in various ways. There is a situation.

Therefore, in order to solve the water shortage phenomenon, various methods for efficiently using rainwater falling naturally have been researched and developed.

However, such rainwater is exposed to various pollutants in the atmosphere and falls down, including the rainwater, and the ground surface is permeated with various pollutants, and thus, the pollutants contained in the rainwater are removed to improve the water quality of the streams. In order to achieve this, there is a need for an excellent purification facility.

In general, pollutants include point pollutants and agricultural land, pastures, forest lands, construction sites, mines, logging sites, waste disposal plants, wastes, etc., which are discharged from defined and limited point sources such as rainwater, 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 the point pollutants having a clear discharge point among the pollutants as described above, a separate purification device or wastewater treatment facility is installed in homes, factories, livestock farms, etc. 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.
