This study was construct Test bed of eco-friendly filtering system in Busan Eco Delta City. The purpose of T/B construction was to develop of eco-friendly innovation technology for improvement of river water quality and cleaning of water supply raw water. T/B consisted of Module 1 and Module 2. Module 1 consisted of pond-algae mat-roughing filter and module 2 consisted of pond-wetland?roughing filter. In each unit process, the pond was constructed to supply stable flow rate to the subsequent process and pre-treatment of particles such as algae. In the case of algae mats, it was constructed as a facility to remove phosphorus in the stream while propagating the mushy algae. It is designed as a facility to remove pollutants in an eco-friendly manner using vegetation, and additional phosphorus removal is considered through functional media. The last step, roughing filter is a horizontal flow filtration with medium velocity, and to collect the contaminants by the internal filtration method and to remove them by the attached microorganisms by densified the filtration particle size toward the downstream. The results of this study was as follows. The nitrogen and phosphorus removal efficiencies of Module 2 were higher than Module 1. Finally We derived design and operation factor and process decision tree for determination of combination process by water treatment purpose using Busan EDC eco-filtering test bed. |
