以典型氯代烃污染场地为试验基地，采用原位注入方法，研究了添加强化药剂对地下水氯代烃厌氧还原脱氯降解和化学环境变化的影响。结果表明，强化药剂能有效促进氯代烃污染地下水的原位还原修复，且对1，1，1-三氯乙烷、1，1-二氯乙烷的去除效果（平均去除率>99%）好于对1，1-二氯乙烯的效果（平均去除率78.9%）；药剂最佳作用时间为注入后90 d内，最佳作用半径为1.5 m，主要作用途径为药剂中缓释有机碳介导的厌氧生物还原脱氯。

A typical chlorinated hydrocarbon-contaminated site has been chosen as the test base. By using in site in-jection,the effects of adding strengthened chemicals on anaerobic reductive dechlorination degradation of chlorinat-ed hydrocarbons and chemical environmental changes in groundwater have been studied. The results show that the strengthened chemicals can efficiently facilitate the in situ reductive remediation of groundwater polluted by chlori-nated hydrocarbons,and the removing efficiency of 1,1,1-trichloroethane and 1,1-dichloroethane(average remov-ing rate>99%) is better than that of 1,1-dichloroethylene(average removing rate is 78.9%). The best reaction time period is within 90 d after injection,the optimal effect radius is 1.5 m,and the major action pathway is the pro-motion of anaerobic biological reductive dechlorination induced by controlled-release organic carbon in chemicals.
