Abstract

Three reaction media (zero valent iron, activated carbon and modified bentonite) were used to design four kinds of permeable reactive barriers (PRB) and study the feasibility and the efficiency of the PRB technology in the remediation of landfill leachate. The results indicated that PRB is highly effective for the treatment of landfill leachate. The ammonium removal rates in the two reaction media with zero valent iron and modified bentonite was 97.58% at maximum, the removal rate of COD in reactors with zero valent iron and activated carbon was 84.87% at maximum, and the removal rate of total phosphorus in PRB reactors was 80% at maximum.
