| Abstract: | Based on the column experiment of transportation of TCE and PCE, and on the nyctrogeocnemical properties of groundwater in the study area, we set up a mathematical model of transportation and transformation of TCE and PCE with biodegradation, with the fate of TCE, PCE being simulated on computer. The coincidence of computation results with measured values shows that the mathematical model is reasonable, and that biodegradation does exist in study area. Through this study, the scientific basis for subsequent treatment of organic contaminants are well-established. |
