초록
정유폐수의 성상에 적합한 동역학적 모델을 적용하여 활성슬러지법으로 처리할 때 모델의 적합성을 검토하기 위하여 실제 정유폐수 처리장 포기조내의 환경인자의 변화와 유출수 특성을 비교하였다 활성슬러지 포기조내 DO, pH, MLSS, COD의 실제 측정값과 비교하였다. Simulation한 결과, 유출수 평균 COD가 19.0~19.4mg/L로 측정 COD 23.1mg/L와 잘 일치하였고, 포기조내 평균 DO는 1.9~2.4mg/L로 예측되었는데 측정된 평균 DO가 2.2mg/L로 잘 일치하여 모델의 정유폐수 처리장의 적용 가능성이 검토되었다.
A dynamic model was applied to compare the environmental parameters and effluent characteristics of refinery wastewater in activated sludge treatment. The measured DO, pH, MLSS, and COD values were compared with the simulated their results in the activated sludge reactor. As results of simulation. good agreements between the measured and simulated results were investigated. The simulated and measured effluent COD were 19.0~19.4mg/L and 23.1mg/L. respectively. The simulated and measured DO were 1.9~2.4mg/L and 2.2mg/L. respectively.
