Environment Friendly Constructed Wetland System For Nonpoint Source Polluted Water Treatment

摘要

The present invention creates an environment in which natural purification functions such as soil microorganisms can be activated to decompose pollutants attached to vegetation plants and topsoil, thereby maximizing the reduction of pollutants and allowing the inflow of water into wetlands even during continuous rainfall. An inlet formed to prevent the flood, and to purify the water in addition to the natural purification and discharge the water to maximize the water purification capacity, so that water mixed with non-point pollutants flows during rainfall; A first outlet located at an opposite side at a distance from the inlet and configured to allow the purified water to flow out naturally; A sedimentation basin is formed to temporarily store water introduced through the inflow portion until it is discharged to the first outflow portion, and a sedimentation basin in which suspended solids are mixed in water is formed. The wetland is provided with a vegetation wetland is planted, the wetland portion is formed in the position adjacent to the first outflow portion while the sedimentation pond is formed to reduce the flow rate of water while removing the soil; Provides an eco-friendly artificial wetland system for non-point pollutant treatment, including; a second outlet portion that is buried in the lower side of the first outlet portion and flows into the wetland portion and then naturally drains the purified water.
