It provides a non-point pollution treatment apparatus using an active bio-carrier to be discharged into a trench, a river or a river.

In general, non-point pollution refers to agricultural land, grassland, forest land, construction sites, mines, logging sites, and wastes, which emits unspecified water pollutants in unspecified places, unlike pollutants such as household sewage, factory wastewater, livestock wastewater, etc. Discharge areas can be divided into nonpoint pollutants emitted from a wide range of nonpoint sources, such as treatment plants, landfills, urban areas, roads, and industrial sites.

These nonpoint sources pollute water by flowing into rivers or lakes without special refining facilities, with rainwater or snow melts of pollutants, but there is a difficulty in preventing pollution.

In particular, the non-point pollutants are heavy metals, pathogenic microorganisms, organic compounds, radioactive materials, toxic substances, and other contaminants, floating materials and oil strips, which are swept by rainwater during rainy weather, such as rivers, rivers, lakes, etc. Not only does it flow as a major contaminant of water quality, but also causes the destruction of ecosystems and ultimately seriously damages humans.
