Abstract

In this study, in order to analyze the water purification efficiency according to the influent water conditions of artificial wetlands, the purification efficiency was compared at two points where sewage treatment water flows in and one point where good effluent flows in. As a result of reviewing the results of the analysis of influent and effluent and the removal efficiency, the T-N and T-P removal efficiency was calculated at 54.7% and 77.4%, respectively, for the two points where sewage treatment water was treated, the treatment efficiency of SS 90.8%, BOD 51.1%, TOC 30.6%, T-N 38.8%, T-P 55.3% was shown. As a result, the efficiency of removing pollutants in the artificial wetland was found to be proportional to the concentration of influent water, and in order to create an efficient artificial wetland, it is judged that thorough review and management at the design stage are necessary considering that the removal efficiency of high-concentration contaminated water was high.

본 연구에서는 인공습지의 유입수 조건에 따른 수질정화 효율을 분석하기 위하여 하수처리수가 유입되는 2개 지점과 우수 유출수가 유입되는 1개 지점에 대해 정화효율을 비교하였다. 유입수 및 유출수 분석 결과와 제거효율을 검토한 결과, 하수처리수를 처리하는 2개 지점의 경우 T-N과 T-P 제거효율이 각각 54.7%, 77.4%로 산출되었으며 우수 유출수가 유입되는 1개 지점의 경우 SS 90.8%, BOD 51.1%, TOC 30.6%, T-N 38.8%, T-P 55.3%의 처리효율이 나타났다. 결과적으로 인공습지의 오염물질 제거효율은 유입수 농도에 비례하는 것으로 나타났으며, 효율적인 인공습지를 조성하기 위해서는 고농도 오염수에 대한 제거효율이 높았던 점을 고려하여 설계단계에서의 철저한 검토와 관리가 필요한 것으로 판단된다.
