A pilot and field investigation on mobility of PCDDs/PCDFs in landfill site with municipal Solid waste incineration residue

摘要

A field investigation by boring was carried out in a landfill site primarily with municipal solid waste incineration residue. From the collected core samples, vertical profiles of homologous content of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans(PCDDs/PCDFs) in the landfill layer were traced and the behaviour of PCDDs/ PCDFs was examined. In addition, a pilot-scale study was conducted on the PCDDs/PCDFs leached from incineration Fly ahs and the treated one using large landfill simulation columns(lysimeters) and the leaching behavior of PCDDs/ PCDFs was examined.
