Abstract
Solidified sludge can be regarded as a new type of earth cover material for domestic waste landfill. But the acidic environment result from the leachate in landfill is a potential threat to cement-based material. In order to evaluate the deterioration risk of solidified sludge in acidic environment, the leaching process of solidified sludge components under different pH conditions was investigated by taking Ni and Cr as the indexes of semi-dynamic leaching test. Under strongly acid environment (pH = 2), the leaching rate of Cr is significantly higher than that in the weakly acid environment or nearly neutral environment, and the diffusion coefficient increased by an order of magnitudes. The leaching and diffusion coefficients of Ni undergo a small influence from the adding amount of cement and pH value. Both Ni and Cr have relatively low migration ratio.
