中文摘要：

利用实验室土柱淋溶试验,模拟研究化学反应井对地下水中四氯化碳的去除机理和方法。结果表明,四氯化碳在土壤垂直迁移中有滞后现象,200 h后由于截流作用底部取样口浓度高于初始浓度;实验表明50目的铁粉对四氯化碳的转化效果高于其它2种;木炭的吸附效果高于焦炭和椰壳炭;研究发现在双金属共同作用中,铁锌组合优于铁铜组合、铁铅组合。同时采用响应曲面法对多因素进行了优化试验,结果表明：活性炭添加量25.7 g、环境pH值6.1、Fe0/Zn00.858条件下,四氯化碳转化率达到最高值69.4%。研究结果对地下水中有机物的治理具有积极意义。

英文摘要：

Leaching experiment in soil column was used to simulate mechanism and method of chemical reactions well for disintegrating carbon tetrachloride（CTC） in groundwater. Results showed that carbon tetrachloride has hysteresis in the vertical migration of soil, and due to the interception, concentrations of bottom sampling ports was higher than the initial concentration after 200 h. Conversion effect of carbon tetrachloride by iron powder of 50 mesh was higher than the other, and charcoal adsorption was higher than coke and coconut shell charcoal. It was found that combination of iron and zinc was higher than the combination of iron and copper as well as combination of iron and plumbum in bimetal joint. Response surface methodology was used to optimize multi-factor of the experiment. Results showed that CTC highest conversion rate was69.4% under the conditions of activated carbon 25.7 g, pH 6.1, Fe^0/Zn^00.858. The results have positive implications for the treatment of organic matter in groundwater.
