The large-scale experimental channels were constructed in the Takaya river course which a branch of the Ashida river, in Fukuyama-city. This study is one of the experiments by plants purification method. In this study, three channels were used for purification tests by plants such as reed, sweet yellow flag and another channel which called a control channel were paved by nothing. The polluted river water is conducted into 3-plants channels by pumping during about 6 months, from May to October, 2003. The purification effects were estimated by several items of water quality and biological analyses. At three points so as upstream, midstream and downstream in the three experimental channels. In this paper, items such as characteristics of BOD, nitrogen and phosphorus were especially considered from both particle component and the dissolved component Epiphytic algae was evaluated due to those population density, appearance genera, etc.
