The vegetation structure of non-point pollution water treatment system with reusing the rain water drainage}

The present invention relates to a non-point source water purification treatment system having a vegetation structure that reuses rainwater, and more particularly, purifying and filtering rainwater containing non-point contaminants to store purified water from which the boiling point contaminants have been removed and dried. By automatically supplying the stored rainwater to the vegetation plant in India, the vegetation plant grows well without dying out, and the treatment of rainwater containing pollutants and the beautiful urban aesthetic and city through the vegetation plant The present invention relates to a non-point source water purification system having a vegetation structure that reuses rainwater to create an ecological environment.

In general, plants are planted on the edges of India, providing a beautiful environment and clean air to the city so that people can live in a pleasant environment.

Plants installed along these roadsides are exposed to the outside environment, making it difficult to receive careful management, especially when there is no rain, such as droughts, which often lead to dryness or significant damage.

On the other hand, on the road where people and vehicles exist, a boundary block for dividing the sidewalk and the roadway is disposed, and a drainage system including a collecting pipe is installed at the edge of the road formed inside the boundary block to prevent rainwater from accumulating. In the construction, the rainwater flowing from the road is drained in real time through the collecting pipe to prevent rainwater from overflowing to the road and sidewalks.

The drainage system installed on the side of the road is to discharge rainwater through the sewer pipe, the rainwater is smoothly discharged to the drainage system while preventing a large amount of various wastes and garbage from entering the catchment, as well as vehicles or people A grating is installed to make this pass safely.

On the other hand, in case of rainwater, dust or garbage in urban areas, air pollutants that fall on the ground, traffic pollutants, animal and plant residues, soil erosion, barn spills, fertilizers or pesticides applied to farmland, etc. Runs off the ground

Rainwater, which is discharged with contaminants on the surface when it rains, is the main nonpoint source, especially when it rains.In particular, rainwater sources that contain large amounts of nonpoint pollutants such as oil, grease or tire dust on roads Since there is no water purification function, many problems occur such as environmental damage caused by water pollution.

However, the conventional drainage system simply drains rainwater flowing from the road in real time through the water collecting pipe to prevent rainwater from overflowing into the road and sidewalk, so that the nonpoint pollutant containing nonpoint pollutants is discharged to the river. Causing secondary environmental pollution by nonpoint pollutants.

In addition, rainwater is wasted because it is discharged in real time without storing or reusing rainwater, and it is drained through sewage pipes and rainwater does not flow smoothly into the road ground, resulting in low water content of the ground, which leads to depletion of groundwater and urban areas. Problems causing desertification have been pointed out.
