In this study, water hyacinth plants(Eichhornia crassipes), water parsley(Oenanthe javanica) and Lemna paucicostate were used to treat contaminants such as COD, T-N and T-P in far m·fishing village wastewater. The results were as follows : In the batch system experiment, water hyacinth was showed at the high removal efficiency in the 173∼412kgCOD/ha·day concentration that is rather than 260mg/1 of the high concentration. The next is Oenanthe javanica, Lemna. Oenanthe javanica was showed the high removal efficiency in the 96∼173kgCOD/ha·day concentration that is less than 260mg/1 of the low concentration.
