| Abstract: | Objective] This study was to research the treatment effect of different media in undercurrent wetland on contamination, so as to provide reference for rehabitating water body of river along small towns. Method] Three different media of gravel, cobblestone and shale were used to rehabilitate water quality of contaminated river. Result] Gravel, cobblestone and shale all performed well in removing TN, TP and CODMn in contaminated water, of which gravel stuffed undercurrent wetland run best, averagely removing 49.4% TN, 34.7% and 48.5% CODMn, respectively. Conclusion] Undercurrent constructed wetland can effectively improve the water quality of contaminated river, and it is cheaper in cost and simpler in operation, thus suitable for generalizing in small towns of China. |
