Description

Non-point pollution source treatment apparatus using the purifying unit

The present invention relates to a non-point pollutant purification device using a purification unit, and more particularly, to a non-point pollutant purification device using a purification unit united to facilitate the separation and installation of the purification unit.

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 such 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 air and falls down, and the surface is permeated with various pollutants to the rivers, so that the water quality of the streams is improved by removing the pollutants contained in the rainwater. In order to achieve this, there is a need for an excellent purification facility.

In general, pollutants include point pollutants and agricultural lands, grasslands, forest lands, construction sites, mines and logging sites, which are discharged from a limited and limited point source, such as domestic rainwater, industrial wastewater and livestock wastewater. Discharge areas can be divided into nonpoint pollutants emitted from a wide range of nonpoint sources, such as waste treatment plants, landfills, urban areas, roads and industrial sites.

If no action is taken on stormwater treatment facilities around non-point sources, or only the various rocks, oils, and heavy metals provided by nonpoint sources are removed, untreated organic matter flows into the rivers, acting as a major source of pollution.

Therefore, it is required to install a prevention facility for treating nonpoint source. During the development project, nonpoint source planning aims to minimize the area and duration of exposure to rainfall and to minimize surface soil bridge work in areas or slopes where nonpoint pollutants are likely to leak. In addition, the soil for backfilling to be used in the soil, aggregate collection process stored in the field is covered so as not to be exposed to rainfall and installed a drainage channel to allow the soil to be discharged during precipitation to be collected into a non-point source facility.

In the case of point pollutants, pollutants have been purified by installing separate purification devices or wastewater treatment facilities in homes, breakdowns, and livestock farms.However, in the case of nonpoint pollutants, the discharge area is not only extensive. Most of them remain on the earth's surface, but they are introduced into public waters and groundwater such as rivers, bays, and lakes with rainwater during rainy weather, which causes water pollution.

 Conventional techniques for treating such nonpoint sources include natural facilities such as reservoirs, artificial wetlands, infiltration facilities, vegetation-type facilities, filtration-type facilities, vortex-type facilities, and screen-type facilities.

In the case of storage tanks, heavy rains in summer require large-scale land or equipment, and if untreated water is kept, pests such as flies and mosquitoes are generated, which causes hygiene problems. Infiltration type causes soil clogging caused by inflow of soil or suspended materials generated during construction, and vegetation type requires more than a certain amount of land and conditions for maintaining vegetation, but Korea has four distinct seasons. Purification of boiling point contaminants is not constant.

The non-point source treatment apparatus installed in the conventional roadside removes foreign substances piggybacked in rainwater through sedimentation, and discharges rainwater treated through rainwater pipes into rivers, but in this case, only foreign matters separated by rainwater are separated. There was a problem.

The present invention is to solve the problems as described above, and an object thereof is to provide a non-point pollutant purification device using a purifying unit formed to remove foreign substances piggybacked in the rainwater is removed from the foreign matter through precipitation.
