Abstract

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