    摘要:

    分別用堆肥、零價鐵、堆肥-零價鐵作為反應介質,，對PRB處理鉻污染地下水的可行性和有效性進行了研究,。結果表明:以堆肥-零價鐵作為反應介質的反應柱去除Cr(Ⅵ)的效果比單獨以堆肥或鐵粉為介質的反應柱好；增加鐵粉或堆肥的用量均有利于Cr(Ⅵ)的去除；堆肥時間對Cr(Ⅵ)的去除效果影響不大；出水總鐵含量符合《生活飲用水衛(wèi)生標準》要求。

    Abstract:

    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. 
