| Abstract |
Presently, attempts are being made to use aquatic plants for the water purification at an inland water body, however, many problems exist in regard to the techniques and costs involved. In this study, the experiments of water purification using various kinds of aquatic plants at an inland water body site were carried out. Moreover, the application to the site of the water purification techniques using aquatic plants based on the experiment results was examined. The result indicated that some of the aquatic plants showed high removal rate of nitrogen, but it was difficult to achieve stable treatment due to differences of seasonal conditions. In the case of a real application of water purification technique using aquatic plants, it is shown that a very large site is necessary for water purification. Additionally, it is pointed out that using aquatic plants requires a high cost for the water treatment compared to the estimation of the cost of a traditional sewerage treatment system. Aquatic plants for polluted water treatment should be applied to support water purification, to improve the site environment and to construct a healthier biotope as a form of ecomanagement. |
