남창천과 삼향천에 분포한 주요 수생식물의 수질정화능 = The nutrient removal capacity of four aquatic plants distributed in Namchang-chon and Samhyang-chon

다국어 초록 (Multilingual Abstract)

The nutrient removal-capacity of four major dominant species distributed in Namchang-chon polluted with livestock wastewater and Samhyang-chon polluted with industrial and domestic wastewater were investigated.
Water qualities and soil properties of three polluted sites were a quite different in concentration of nitrogen, SS and Ga. Dominant species in livestock wasetewater were Persicaria thunbergii, Zizania latiforia, Phragmites communis and Oenanthe japanica, those in industrial and domestic were Phragmites communis. Changes of NO₃-N, NH₄-N and P concentrations of culture solution are high in cultivor of Zizania latiforia and Oenanthe japanica. All four species removed NO₃-N most effectively. In experiment used directely polluted water from three areas ; all species from livestock wasetewater uptaked NO₃-N effectively. Phragmites communis from domestic, and Persicaria thunbergii and Oenanthe japanica from industrial and domestic wasetewater removed NH₄-N effectively. All species cultured in industrial waserewater removed P well, and Phragmites communis and Persicaria thunbergii cultured in domestic wastewater removed it moderately.
