초록

본 연구는 다양한 유기물과 난분해성 물질들이 포함되어 있는 제약 폐수 내 미생물의 생화학적 특성을 이해하고자 생물학적 동력학 계수를 측정 하고자하였다. 생물학적 동력학 계수는 최대 비성장율과 수율계수, 그리고 반속도상수를 측정하였는데, 각각 10.49/day (0.437/hr), 0.655 그리고 38.89 mg/L로 나타났다. Monod 식의 비선형회귀분석으로 구한 ${\mu}_{max}$ 값 또한 10.63/day (0.443/hr)로 측정되어 두가지 경우에서 구한 값이 유사함을 알 수 있었다. 이러한 생물학적 동력학 계수를 제약 폐수 처리의 활성슬러지 공정의 산소요구량 및 용존 산소 농도 연구와 병행한다면 제약 폐수의 처리 효율 증진 효과를 기대할 수 있을 것으로 판단된다.

The aim of this research is to estimate the values of biological kinetic parameters of pharmaceutical wastewater for understanding biochemical properties. Maximum specific growth rate (${\mu}m$), yield coefficient (Y), and half-velocity coefficient (KS) were determined using oxygen uptake rate (OUR), and the results were 10.49/day (0.437/hr), 0.655, and 38.89 mg/L, respectively. Measured ${\mu}max$ by nonlinear regression of Monod equation was 10.63/day (or 0.443/hr), and this value was similar with above result. These parameters may be used to increase efficiency of pharmaceutical wastewater treatment and to determine amount of oxygen needed to removal BOD and dissolved oxygen in activated sludge process.
