강우유출수의 중금속 제거(Cd, Cr, Cu, Pb 및 Zn)를 위한발포폴리프로필렌 여재를 사용한 EcoTankTM 시스템의 현장적용 : Ucertainty Analysis에 의한 위험도 평가 = Field Application of EcoTankTM System with the Expanded Polypropylene Media for Treating Heavy Metals(Cd, Cr, Cu, Pb and Zn) from Road Runoff : Performance Risk Assessment Using Uncertainty Analysis

다국어 초록 (Multilingual Abstract)

The EcoTankTM system is a part of the road runoff treatment which uses porous expanded polypropylene (EPP) media with a large surface area to treating the first-flush of stormwater from motorway in field. A series of studies have been carried out concerning the main mechanism of physical characteristics with the filtration and adsorption of EPP media in an EcoTankTM system in order to evaluate the performance risk for treating heavy metals (Cd, Cr, Cu, Pb and Zn) under uncertainty. Under the operating conditions with 0.55 h hydraulic retention time (HRT) and a capable of treating a maximum road runoff of 9.5 m3/h, the mean residual Cd, Cr, Cu, Pb and Zn were 0.3, 3.0, 17.6, 11.2 and 122.2 ㎍/L and the corresponding percentage mean removal values were 93.0, 93.1, 85.1, 91.0 and 84.7%, respectively. Predicting the treatment performance of an EcoTankTM system in stormwater treatment is associated with considerable uncertainty. In view of quantitative and qualitative risk analysis, this study assesses the uncertainty involved in predicting of treating heavy metals from road runoff using an EcoTankTM system. Results (risk probability, Class and risk level) of treatment performance estimation after the treatment of heavy metals (Cd, Cr, Cu, Pb and Zn) using an uncertainty analysis were 50.0% probability (Class 3; moderate) for Cd, 52.0% probability (Class 4; high) for Cr, 47.1% probability (Class 3; moderate) for Cu, 44.4% probability (Class 3; moderate) for Pb and 51.2% probability (Class 4; high) for Zn, respectively. The performance risk values or certainty ranges of all the heavy metal satisfied the acceptable criteria (Class 4; risk level (high); risk ranges (51~70%)). Thus, the performance risk assessment is deemed to be of rational, realistic and practical consideration for treatment system in the wider decision-making context of runoff control and operation management.
