This this study was conducted with the aim of doing experiment on the effect of water purification by using an artificially built plant island, which is one of the eco-techniques, and aquatic plants as a plan for the reuse of water for obtaining water resources, thereby analyzing the removed quantity, and applying the experimental results to the reuse of water. As a result of doing experiments, this study obtained a good measured value of BOD (biochemical oxygen demand) 4.7mg/L, and COD (chemical oxygen demand) 7.2mg/L below the heavy water standard of BOD 10mg/L and COD 20mg/L, respectively. The chromaticity showed 89.2% removal efficiency, but final treated wastewater was found to show chromaticity 58 degrees exceeding chromaticity 20 degrees which are the water quality standard of the reuse of water. The results revealed that T-N produced 27% removal efficiency on an average while T-P produced 38% removal efficiency on an average, showing that the removal effect of N & P wasn't big. According to the currently enforced "Water Quality Standard of Heavy Water by Use", the use of water for sprinkling and landscaping was found to be available. Accordingly, this study suggested a nature-friendly, economically-efficient, and eco-technological water treatment technique which will make it possible to overcome the limit of the existing physio-chemical water treatment technology, reduce the costs for maintenance and facilities, and also reduce the limit of space restraint for installation of facilities.
