ABSTRACT OF THE DISCLOSURE: When a bituminous emulsion is added to a water- containing sludge, the sludge is instantaneously separated into an aqueous layer and a solid layer. But, heavy metal and other poisonous pollutants cannot be removed from the separated aqueous layer. In contrast, when a sulfur-containing compound or colloidal sulfur is added to such sludge in combination with a bituminous emulsion, heavy metals and other poisonous pollutants are converted to water-insoluble or hardly soluble sulfur compounds and they are readily removed from the separated water layer. When an inorganic coagulant or organic polymeric coagulant is added in combination, the coagulating and solidifying effects can be further increased. Moreoever, the heavy metals and other pollutants fixed in the solid layer are hardly dissolved out and therefore, the separated solid cakes can be used for reclaiming or as water shielding walls.
