%X A double layer Permeable Reactive Barrier (PRB) experiment was designed to study the feasibility of in-situ remediation of groundwater contaminated by landfill leachate. Zero valent iron (ZVI) was used in the first reactor as fillings to decompose complex non-degradable and less degradable organics such as halocarbon. Then the second reactor was used to treat organic compound completely. It was an ORC reactor filled with Oxygen Release Compounds. The results indicated that the value BOD5/COD increased from 0.32 to 0.75 after through the first reactor. The removal ratio of ammonium and nitrate went up to 85% and 80%, respectively; and the maximum concentration of dissolved oxygen (DO)released by the ORC reactor went up to 7.64mg·L-1. Hence, a double layer PRB to treat leachate-polluted groundwater is feasible to application.
