CONSTRUCTED WETLAND SYSTEM FOR NONPOINT SOURCE POLLUTED WATER TREATMENT

摘要

Artificial wetland system according to the present invention, the sedimentation tank for temporarily storing the contaminated water introduced from the outside to settle and remove the dirt contained in the contaminated water and a constant than the bottom surface of the sedimentation tank downstream of the sedimentation tank along the flow direction of the contaminated water A free water treatment type first purification treatment tank having a first wetland formed at a height and having a first wetland where the first purification plant is planted, and being supplied downstream from the first purification treatment tank along the flow direction of the contamination water; Subsurface flow treatment type 3 purification treatment having a second freezing treatment type second purification treatment tank having a second wetland in which the second purification plant is planted, and a permeation purification unit capable of purifying the contaminated water. The jaws are placed sequentially.;Purification, Polluted water, Artificial Wetland, Purification Tank, Artificial Buoy, Purification Mat, Purifying Plant, Gravel, Sand
