초록

자연정화공법을 이용한 인공습지 폐양액처리장에서 처리효율의 장기간 모니터링을 위해 선행연구를 통해 개발된 폐양액처리 시스템에 최적공법을 적용하여 시기별 수처리효율을 조사하였다. 또한 폐양액 처리장에서 오염물질의 처리경향을 파악하고, 이를 토대로 설계 및 시공시 부지면적 감소와 오염물질의 처리효율 극대화를 위한 기초자료를 제시하기 위하여 오염물질의 분해속도를 조사하였다. 폐양액 처리장에서 시기별 수처리효율 결과 최종 2차 방류수에서 BOD, COD, SS, T-N 및 T-P의 처리효율은 각각 88%, 79%, 92%, 64% 및 92%로서 처리시일이 경과 할수록 점점 안정화 되는 경향으로 특히, 3개월 이후부터는 안정적인 처리가 가능하였다. 폐양액처리장에서 오염물질의 분해속도 K ($day^{-1}$)는 1차 수평흐름조의 경우 SS (0.54) > BOD (0.39) > COD (0.27) > T-P (0.26) > T-N (0.06) 순으로 SS가 가장 빨리 분해되었고, 2차 수평흐름조의 경우 T-P (0.52) > BOD (0.28) > COD (0.15) > T-N (0.06) >SS (0.10) 순으로 전반적으로 T-P가 가장 빨리 분해되었다. 이들 결과를 미루어 볼 때, 본 현장 인공습지 폐양액처리장은 장기간 안정적으로 폐양액을 처리할 수 있을 것으로 판단된다.

In order to develop constructed wetlands for treating hydroponic wastewater in greenhouses, removal efficiencies and decomposition velocities of pollutants in constructed wetland were investigated for treating hydroponic wastewater. Removal rates of BOD, COD, SS, T-N and T-P in effluent in constructed wetlands were 88%, 79%, 92%, 64% and 92%, respectively. The decomposition velocities (K; $day^{-1}$) of pollutants in $1^{st}$ HF bed of constructed wetlands were higher in the order of SS ($0.54day^{-1}$) > BOD ($0.39day^{-1}$) > COD ($0.27day^{-1}$) > T-P ($0.26day^{-1}$) > T-N ($0.06day^{-1}$). In $1^{st}$ HF bed of constructed wetlands, the decomposition velocity of SS was rapid than that for BOD, COD, T-N and T-P in constructed wetland for treating hydroponic wastewater. The decomposition velocity (K; $day^{-1}$) of pollutants in $2^{nd}$ HF bed of constructed wetland were higher in the order of T-P ($0.52day^{-1}$) > BOD ($0.28day^{-1}$) > COD ($0.15day^{-1}$) > T-N ($0.06day^{-1}$) > SS ($0.10day^{-1}$). In $2^{nd}$ HF bed of constructed wetlands, the decomposition velocity of T-P was rapid than that for BOD, COD, SS and T-N in constructed wetland for treating hydroponic wastewater.
