针对好氧工艺与厌氧工艺单一修复污染土壤的不足, 设计组合工艺, 考察了不同污染物在该工艺下的降解率,对微生物土壤修复具有重要意义. 采用本组合工艺,分别以被二氯联苯;邻(对)硝基氯苯;滴滴涕(DDTs);六六六(HCHs)污染的4种污染土壤为对象,研究了各污染土壤在对应的厌氧与好氧菌共同作用下污染物的降解程度. 结果表明:最终污染物的降解率均达到95%以上,说明本工艺可以有效地对难降解有机污染土壤进行修复.铝加入量为硫化砷渣质量的15%时,砷的浸出质量浓度为1.25 mg/L,达到了危险废物填埋污染控制标准.

As efficiency of single soil rem ediation process is limited,the combination of aerobic and anaerobic process was studied. The soil samples, polluted by dichlorobenzene,ortho-nitrochlorobenzene,DDTs and HCHs respectively, were collected. The pollutants degradation of those samples was studied by the bio-degradation of anaerobic and aerobic bacteria. The results show that pollutants degradation rate is above 95%, which means that the combination of aerobic-anaerobic process is effective.
