Abstract:

The ability of type II portland cement, hydrated lime, and AC-10 asphalt to solidifystabilize municipal solid waste MSW incinerator residues was evaluated. Leachate withdrawal was controlled at 0.13 mlmin until final liquidsolid ratios of 0.6, 0.4, and 0.9 was achieved in the cement, lime, and residue control columns, respectively. The leachates were analyzed for metal Pb, Ni, Zn, Al, Ca, Mn, Na, Cd, Cu, Fe and anion Cl, SO4, NO3, PO4, Br concentrations, alkalinity, pH, redox potential, and conductivity. Successful immobilization of all tested metals except lead, aluminum, and nickel, were seen in the cement amended leachates, while only zinc and manganese were leached from the lime amended columns in concentrations exceeding those found in the residue control. The test results revealed little differences in metal mobility between wastes of varying percent amendment addition. In general, cement, lime, and asphalt amended residues demonstrated reduced mobility for cadmium, manganese, and aluminum relative to the concentrations measured in the control leachates. Compressive strength tests were performed on replicate specimens of all cement, lime, and asphalt amended matrices as a measure of residue solidification. Theses.
