Retartation Performance to Pollutants of Antiseepage Slurry for Waste Landfill Sites

Abstract:

Based on self-developed bentonite - fly ash - cement（BFC）slurry and flexible wall permeameter, infiltration test was conducted on slurry concretion samples of different height using heavy metal ions Solution and leachate from waste landfill site. Test proved that as a result of the infiltration deposition and adsorption residence performance, retardation by slurry concretion happened in about 30mm of initial infiltration to 95% of heavy metal ion pollutants(Hg, As, Pb, Cr, Cd etc.) and 60% of waste leachate pollutants (NH₄-N, TN, TP, COD_Cr, BOD₅ etc.). Moreover, blocking rate for all pollutants presents an increasing trend along with the increase of the height of slurry concretion samples in a defined way.
