METHOD OF PROCESSING CONTAMINATED SOIL

摘要

To separate the contaminated soil into a cleaned fraction and a pollutant concentrate, the contaminated soil is ground in a drum with the addition of loose fragments like grinding bodies with a net power consumption of 4 to 16 kWh/t throughput, the rotational speed being 50 - 90 % of the critical rotational speed of: …… …The suspension discharged from the drum is separated by screening into a coarser and a finer fraction, the coarser fraction is removed as cleaned fraction and the finer fraction is desludged. The separated sludge is removed as pollutant concentrate after dewatering, and the desludged residue of the finer fraction is removed as cleaned soil after dewatering. ……
