摘要

"PROCESS FOR THE THERMO-CHEMICAL REMEDIATION AND DECONTAMINATION OF CONTAMINATED MATERIALS INCLUDING SEDIMENTS AND SOIL CONTAMINATED WITH ORGANIC MATERIALS, INORGANIC MATERIALS AND HEAVY METALS". This invention relates to the remediation and decontamination of sediments and soils contaminated with organic and inorganic contaminants. Environmentally stable products are produced when certain additives such as calcium oxides are mixed with contaminated materials. In the process, the mixture is heated to produce a reaction product melted with at least part of an excessive amount of oxygen or air mixture continuously bubbled through the melted material (16) in order to supply the mixture and achieve thermal destruction and removal high effects of organic contaminants. The molten material (16) is then rapidly cooled in moist air, steam or water to prevent the amorphous material from becoming crystals. Inorganic contaminants such as chromium, nickel and zinc are incorporated and completely immobilized within the amorphous silicate network. The amorphous material can be sprayed to yield a powder that shows the cement properties by mixing it with other materials for the production of mixed cements.
