FIELD-TEST AND MATHEMATICAL-MODELING OF BIOREMEDIATION OF AN OIL-CONTAMINATED SOIL .2. MATHEMATICAL-MODELING

A mathematical model was developed to describe the oxygen transfer fro m the air, the oil transfer from the soil, and the bio-reaction in the aqueous phase. Important parameters used in this model were obtained independently either in the laboratory or from the literature. The oil transfer rate constant, K(i)a, was found to be a function of time dur ing the remediation. The oil transfer rate controlling in this bioreme diation process is confirmed again by the parameters obtained from sim ulation results for each plot. An example of calculation was used to i llustrate the oil transfer controlling step in the bioremediation of o il contaminated soil.
