CURRENT STATUS |OF CLAYEY SEEPAGE CONTROL SYSTEM |FOR |MUNICIPAL SOLID WASTE LANDFILL

The seepage control system in municipal solid waste (MSW) landfill is to prevent the spread of pollutants. This paper presents a literature review of the studies on clayey seepage control systems in MSW landfills. It further presents the mechanism of clayer seepage control system. The developments of the studies of the clayey seepage control systems in MSW landfills include the retardation characteristics, the contaminant transport, the modification and substitute, and the design on the seepage control system. It is pointed out that the unsaturated permeability, adsorption effect and optimize design based on adverse-adsorption are the key topics in the future study of clayey seepage control systems for MSW landfills.
