摘要： A method for removal of hydrocarbon materials from solid particulate soil contaminated with the hydrocarbon materials. The method comprises forming an aqueous slurry of a mixture of a hydrophobic adsorbent selected from foamed synthetic materials or natural materials which entrap gas, with the soil in the presence of water. The adsorbent has a density less than water. The slurry is mixed for a period of time, and a gravity separation of the adsorbent from the aqueous admixture thus obtained is effected.

摘要： The present invention relates to a process for cleaning mercury-contaminated soils that is simple, efficient and safe to use. This process can also be used to clean soils contaminated with additional metals, such as zinc, copper and lead, at a lower pH. The present invention involves screening the contaminated soil to remove unwanted materials, leaching the contaminated soils with hypochlorite in a screw reactor, thickening, leaching with hypochlorite and sodium chloride, thickening again and then separating the mercury-containing liquids from the clean soil. This invention also relates to a process which uses sulfide to treat the mercury-containing liquids.

摘要： A recycling system treats petrochemical types of hazardous waste for disposal. Such waste typically includes in large part, a mixture of hydrocarbons, water, solids (soil particulate), and metals. The recycling system separates the water, solids, hydrocarbons, and metals from one another. The recycling system includes the following processing steps:(1) mixing the hazardous waste with a water-miscible washing medium, and agitating the mixture for separating water and some hydrocarbons from solids;(2) removing hydrocarbons from solids by mixing the solid/hydrocarbons with a washing medium that is nonmiscible with water, and agitating the mixture for dissolving hydrocarbons in the solids;(3) removing metals from the separated solids by mixing the separated solids with an acidic washing medium, and agitating the mixture for dissolving metals from the separated solids into liquid solution; and(4) subjecting the separated solids to an alkaline washing solution for neutralizing acidity in the separated solids, and thereafter drying the separated solids for removal of moisture for disposal of the separated solids.Processing in accordance with the invention, provides separated water and soil particulate substantially free of contamination by hydrocarbons and/or toxic/RCRA metals, and thus may be reintroduced into the environment, the water sewered, and the metals recycled.

摘要： A method for treating a quantity of soil contaminated with lead, copper or mercury includes mixing the contaminated soil with an acid, chloride solution, to dissolve the contaminants in the chloride solution. Soil, essentially free of the contaminants, is separated from contaminant-containing chloride solution. Contaminants are precipitated from the contaminant-containing chloride solution by addition of one or more sulfides. Precipitated contaminants are separated from the remaining solution. The remaining solution may treated by adding chloride, acid, ORP adjusting agents and used to treat an additional quantity of soil.

摘要： A process for in situ remediation of contaminated soils and/or residues is disclosed. This process takes advantage of a horizontal radial flow irrigating/draining system and sensors (8) located at midspacing between parallel conduit lines (5) to create an environment propitious to the action of decontaminating agents (plants, microorganisms, salts, acids, bases, buffers, enzymes, substrates, surfactants, etc.). For example, a water-saturated zone may be created, the level of water containing decontaminating agents is raised, maintained and/or lowered, which water-saturated encourage desorption or solubilization of soluble contaminants, by adjusting and controlling all the parameters of reaction (time, temperature, pH, oxygenation, etc.) The process is easily adaptably for many classes of contaminants, including volatile compounds and light non-aqueous phase liquids, by further installing supplementary sets of conduit lines and pumping means at adequate levels. The site may be remedied by alternating gaseous and liquid modes to optimize the conditions of reaction, which alternation is advantageously achieved in a multi-unit arrangement, one unit being in gaseous mode while another is in liquid mode.
