高屋川の現地水路(接触酸化・植栽)における水質浄化効果と生物群の消長に関する相互評価

This study is one of the on-site experiments on purification of water quality by Plants Experiment and Contact Oxidation Material. The large-scale experimental channels were constructed in the Takaya river course. In this study, three channels were used for purification experiments by reeds, coal-ash grains, and nothing paved. The river water is conducted into 3 channels by pumping during about 6 months, from May to October, 2004. The purification effects were estimated by several items of water quality and biological. In this paper, items such as characteristics of nitrogen and phosphorus were especially considered from both particle component and the dissolved component. Biology were evaluated due to those population density, appearance genera, etc
