Description

Nonpoint Source Contaminant Treatment Apparatus of Road}

The present invention relates to an apparatus for treating nonpoint pollutants on a road. More specifically, the rainwater flows on a road during rainfall, and the initial rainwater containing nonpoint pollutants on the road surface is cleaned by vegetation. By separating separately, the present invention relates to an apparatus for treating non-point pollutants on roads, which is not only easy to maintain the facility, but also has a landscaping structure to reproduce various patterns of vegetation to achieve excellent environmental decoration.

In general, the sources of water pollution are classified into point sources and nonpoint sources. Point sources and nonpoint sources are relative concepts. Point sources are pollutants that are discharged from places where the contaminants are clearly discharged, such as domestic sewage or factory wastewater. Nonpoint source refers to a pollutant in which pollutants flow out unspecified along with rainwater during rainfall on roads, farmland, mountains, and construction sites in cities.

Therefore, the point pollution source is easy to collect because of its clear outflow route, and there is no big change in the discharge regardless of rainfall. Therefore, it is possible to predict the yearly amount as the seasonal influence is relatively small, so the design and management of treatment facilities such as conduits and treatment plants On the other hand, nonpoint pollutants are difficult to collect because they are leaked during rainfall at unspecified places, and their discharge paths are not clearly distinguished, and it is difficult to design and maintain treatment facilities because the amount is affected by weather conditions such as rainfall. .

Among these non-point sources, urban non-point pollutants include sediments and air pollutants on roads, all of which are swept away by rainwater and run out to rain gutters installed on the side of the road to treat road runoff. And as it enters the appeal, it acts as a cause of disturbance of the aquatic ecosystem by destroying the population death of fish or the habitat of benthic organisms due to water pollution.

In addition, due to the recent urbanization, facilities with water impermeable materials (for example, asphalt or concrete) are increasing, and the rainfall is continuously discharged to rivers or lakes without being absorbed into the soil or evaporated during rainfall. There was a problem such as the decrease in the induction of dryness of the river during rainy days.
