Abstract

Potential of groundwater contamination by trichloroethylene (TCE) and other volatile organic compounds VOCs near car industry was conducted in this study. TCE, PCE, toluene, xylene, dichloromethane, cyclohexane, n-hexane and n-pentane were detected in all groundwaters. Mean TCE levels in groundwater ranged from 124.37 to 1,035.9 μg L⁻¹ with maximum level of 1,345.7 μg L⁻¹. Due to the data obtained from conventional wastewater treatment in car factory the TCE removal efficiency was only 24 percent which necessitates the TCE removal by advanced treatment processes before the use of well water.

摘要

本研究对汽车工业附近地下水中三氯乙烯（TCE）和其他挥发性有机化合物（VOCs）的潜在污染进行了研究。所有地下水中均检测到 TCE、PCE、甲苯、二甲苯、二氯甲烷、环己烷、正己烷和正戊烷。地下水中 TCE 的平均浓度范围为 124.37 至 1035.9μg/L，最高浓度为 1345.7μg/L。由于从汽车厂常规废水处理中获得的数据，TCE 的去除效率仅为 24%，因此在使用井水之前，需要采用先进的处理工艺去除 TCE。
