摘要
采用动态和静态试验相结合的方法,考察了零价铁(ZVI)、活性炭(GAC)、零价铁和活性炭的混合物(ZVI+GAC)对地下水中三氯乙烯(TCE)污染物的去除效果。试验结果表明,ZVI、GAC和ZVI+GAC均能有效地去除TCE,其中以质量比为1∶1的ZVI+GAC混合物在水流流速为25 mL/min时效果最佳,其对TCE的去除率超过85%。
Dynamic and static test methods are used to investigate the removal efficiency of trichloroethylene pollutants by different medium of zero - valent iron, activated carbon, the mixture of zero - valent iron and activated carbon. The test re suits show that： zero - valent iron, activated carbon and the mixture of zero - valent iron and activated carbon can effectively remove trichloroethylene, especially by using the mass ratio of 1 ： 1 mixture of zero valent iron and activated carbon, the efficiency is best and the removal rate of trichloroethylene is over 85% at flow rate 25 mL/min.
