상수원 상류지역 인공습지의 5년간 수질 정화효율 평가

This study evaluates treatment efficiencies of pollutants in Boknae bio-park constructed wetlands surrounding Juam Lake for 5 years from January 2006 to December 2010, in order to treat non-point pollutants effectively. The analysis of monthly treatment efficiency of pollutants shows that the scope of BOD is –19.11∼ 37.72%, and of COD is 30.14∼27.38%, thus the monthly deviation COD is relatively higher than BOD, and the scope of SS is –54.07∼64.82%. Moreover, the analysis of seasonal treatment efficiency of pollutants shows that the treatment efficiency of TN is higher than 36.8% on average for 5 years in the spring and winter, and of TP relatively lower than other pollutants, however, the seasons don’t make much difference to the treatment efficiency of TP.
