Description

{Non Point Pollution Reducing System}

More particularly, the present invention relates to a non-point pollution abatement facility, and more particularly, to a non-point pollution abatement facility that is capable of preventing pollution of the water quality of the river by collecting and purifying pollutants from the ground surface Facilities.

Generally, water pollution sources are classified into point pollution source and nonpoint pollution source.

Here, the point source is relatively easy to trace the area and amount of occurrence such as domestic wastewater generated in general households or business areas, industrial wastewater discharged from factories, and livestock wastewater generated in large-scale livestock facilities, while non- It is not easy to track the area and the amount of the generation such as agricultural, grassland, forest, construction site, mine, logging paper, waste disposal site, waste landfill, urban area, road and industrial site.

Non-point pollutants generated from non-point pollution sources have a wider range of pollutants compared to point pollutants, and they are mostly present on the surface of the ground. However, the pollutants that enter the public waters such as rivers, It is becoming a main cause.

These non-point pollutants are reported to have a relatively high pollutant concentration in the early rain during rain, so it is important to remove the initial pollutant sources.

Techniques for reducing existing non-point pollutants include a technique of installing a horizontal screen to remove contaminants and installing a screen, and passing pollutants such as zeolites or activated carbon through the filter media to remove contaminants In addition, there is a technique of forming a filter medium such as sand, activated carbon, and zeolite to allow the filter medium to pass through the filter medium layer from the top to the bottom or through the filter medium layer from the bottom to the top.

However, techniques for reducing existing non-point pollutants have a problem that since the specific gravity of the media layer is larger than that of water and the media layer is fixedly packed, the media layer is frequently clogged by fine turbidity at the time of admission, There is a limit in reducing the amount of the material and there are problems in that various methods for treating the initial rainfall runoff are not effective in actual application.
