WASTE-TREATING MATERIAL

摘要

Disclosed herein is a waste-treating material which comprises cement and at least one reducing metal, effective for stabilizing industrial wastes containing harmful metals like a heavy metal and the like and cyanides. A preferred example of the reducing metal is iron. Additionally the wastetreating material may also contain at least one member selected from a group consisting of a reducing agent, aluminum sulfate, allophane, and bentonite as the auxiliary. The use of this waste-treating material makes it possible to stabilize the hazardous heavy material and the cyanides contained in the industrial wastes, thereby remarkably contributing to a stabilizing treatment ofthe industrial wastes.
