摘　　要：实验采用还原性铁基矿物、碳源和微生物菌剂对六六六污染土壤进行修复研究。结果表明,还原性铁基矿物和菌剂联用和单独使用均对六六六产生明显降解效果,其中还原性铁基矿物+有机碳源处理效果最佳,添加还原性铁基矿物也能取得较好效果。实验组降解产物中1,2,4-三氯苯浓度变化较为明显,随着剩余六六六的降解,在3 d时,所有处理组1,2,4-三氯苯浓度均有所增大,在7 d时所有处理组均能完全还原降解六六六及其含氯降解产物。The experiment used reducing iron-based minerals,carbon sources,and microbial agents to study the remediation of soil contaminated with hexachlorocyclohexane.The results showed that the combination and individual use of reducing iron-based minerals and microbial agents had a significant degradation effect on hexachlorocyclohexane.Among them,reducing iron-based minerals+organic carbon source treatment had the best effect,and adding reducing iron-based minerals could also achieve good results.The concentration of 1,2,4-trichlorobenzene in the degradation products of the experimental group showed significant changes.As the remaining hexachlorocyclohexane was degraded,the concentration of 1,2,4-trichlorobenzene increased in all treatment groups after 3 days.At 7 days,all treatment groups were able to completely reduce and degrade hexachlorocyclohexane and its chlorine containing degradation products.
