Embodiment Construction
[0027] A mine pit in Huainan City needs to be backfilled. At the same time, there is a large amount of river dredging silt that needs to be treated. The silt is rich in a large amount of pesticide residues (herbicides). Considering comprehensively, the dredged silt is used as the contaminated soil raw material to prepare fluidized mine pit backfill soil to backfill the mine pit. The specific implementation steps are as follows:
[0028] (1) Determine the raw material ratio for on-site construction: According to the laboratory test results, determine the raw material ratio of the contaminated soil. The control standards include the fluidity and the diffusion characteristics of soil pollutants after solidification. The components of the dredged silt are determined to be: contaminated soil 95~ 105 parts, 30 parts of curing agent, 50 parts of water, 20 parts of activated carbon powder, 5 parts of water reducing agent, 15 parts of quicklime, 20 parts of expansive soil, 15 parts of ...
