SIMPLE METHOD FOR DETERMINING BREAKTHROUGH TIME FOR ANTI-SEEPAGE LINER OF LANDFILL
The present invention relates to a simple method for determining breakthrough time of anti-seepage liners in a landfill. The method includes the following steps: (a) detecting a leachate sample of the landfill to determine the initial concentration C 0 of typical pollutants, and monitoring the leachate head h of the landfill; (b) determining the harm-causing or pollution-causing concentration C A of the pollutants according to functional orientation of local groundwater of the landfill; (c) determining, through researches, related parameters of the anti-seepage liners and related parameters of pollutant migration, the related parameters of the anti-seepage liners including the thickness z of the seepage liners, the permeability coefficient k of the liners, and the porosity n of the material of the liners; and the related parameters of pollutant migration including the effective diffusion coefficient D a * and the mechanical dispersion coefficient D m of the pollutants in the anti-seepage liners, and the adsorption retardation factor R d of the anti-seepage liners on the pollutants; and (d) calculating the breakthrough time t of the anti-seepage liners according to a formula (1). The method can be widely applied to design, management, subsequent repairing and other work of anti-seepage liners in a landfill.
