摘要
根据室内三氯乙烯(TCE)、四氯乙烯(PCE)运移转化的土柱实验和研究区地下水化学特征,建立了研究区微生物作用下TCE、PCE迁移转化的数学模型,并进行了计算机数值模拟,模拟结果与实测值基本一致,表明本次研究建立的数学模型是正确的,研究区地下水中存在生物降解作用,为下一步有机污染的治理提供了科学依据。
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.
