Abstract
PURPOSE: To generate solidified material containing heavy metals from sludge by adding sodium silicate and thioalcohol to sludge containing heavy metals such as muddy sludge or the like.
CONSTITUTION: Sodium silicate or its hydrate and thioalcohol are added to sludge containing heavy metals such as muddy sludge or the like to adjust pH to 7 to 8 to thereby produce solidified material containing the heavy metals from the sludge. Then, the solidified material is separated from supernatant liquid. The solidified material thus separated is pressurized and dehydrated to form a cake for burying material or the like.
