Abstract

This study employs sulphoaluminate cement as the primary solidifying agent and municipal solid waste incineration bottom ash as the auxiliary solidifying agent to conduct solidification treatment on leachate sludge from domestic waste landfills. The results indicate that: (1) Sulphoaluminate cement demonstrates superior solidification effects compared to ordinary Portland cement in treating leachate sludge; (2) The unconfined compressive strength of the solidified leachate sludge increases with the rise in cement content; (3) Municipal solid waste incineration bottom ash can serve as a skeleton-building material; (4) The synergistic use of waste incineration by-products with sulphoaluminate cement in solidifying leachate sludge for landfill disposal exhibits a certain volume reduction effect.
