Development of Constructed Wetlands Design Model for Water Quality Management in Rural Basins

농촌유역의 수질관리를 위한 인공습지 설계모형 개발

Constructed wetlands are among the recently proven efficient technologies for wastewater treatment. Compared to conventional treatment systems, constructed wetlands are low cost, are easily operated and maintained. Constructed wetlands are particularly sensitive to Nonp oint source pollution(NPSP) because they function as pollutant sinks. The objectives of this study were to review the necessary contents of survey and design factors for constructing constructed wetlands and develop a modified DSS-WQMRA model for design of constructed wetlands. From the results of the case studies, in order to attain BOD target water quality, 0.27%(SF), 0.66%(FWS) wetland area of the total basin is needed.
