Permeable Reactive Barrier Technology for Landfill Leachate Polluted Groundwater Remediation Effect
In this paper seven reaction media zero valent iron (ZVI),activated carbon,zeolites,ceramsite,slag,anthracite,flyash were used to design seven kinds of permeable reactive barrier (PRB),viz.reactors 1,2,3,4,5,6 and 7.The feasibility and the efficiency of the PRB technology in the remediation of leachate-polluted groundwater were studied by successive experimental simulation.The removal effects to the pollutant of the reactors along with the variation of flow velocity,EC and Cl-were analysed to explore the removal mechanism.The results indicated that the COD,Cl-removal ratios were from 82.36%~88.17%,ease that the seepage velocity were from 80~150cm/d.It can be indicated that PRB technology is an efficient method for the treatment of leachate-contaminated groundwater,though it is expected to do further research.
