摘  要:
分别用堆肥、零价铁、堆肥-零价铁作为反应介质,对PRB处理铬污染地下水的可行性和有效性进行了研究。结果表明:以堆肥-零价铁作为反应介质的反应柱去除Cr(Ⅵ)的效果比单独以堆肥或铁粉为介质的反应柱好;增加铁粉或堆肥的用量均有利于Cr(Ⅵ)的去除;堆肥时间对Cr(Ⅵ)的去除效果影响不大;出水总铁含量符合《生活饮用水卫生标准》要求。

摘  要:
With compost,ZVI,and ZVI-compost as reaction media respectively,the feasibility and effectiveness of Cr-polluted groundwater by PRB were studied.The results showed that the reactor packed with ZVI-compost had a better performance than that with compost or ZVI alone;increasing the amount of compost ZVI could increase the removal effects; moreover the removal effects were little influenced by the time of composting;totle iron of effluent meet the requirement of standards for drinking water quality.
