摘要： Process for soil remediation, the contaminated soil being excavated and separated in a screening stage into a coarse fraction and a fine fraction, the fine fraction being decontaminated in a suspension reactor for biological soil treatment, process water being returned to the circulation and the decontaminated soil, if appropriate after readdition of the coarse fraction, being backfilled, a soil analysis being carried out, taking into particular consideration the binding of the pollutants and the pollutant distribution over the grain size categories, a highly polluted soil fraction being separated off from the fine fraction by flotation and the flotated soil being passed to a suspension reactor known per se for biological soil treatment.

摘要： Contaminated soils are treated in that an aqueous slurry of the soil is separated into a coarse fraction and a fine fraction, the fine fraction is subjected to flotation, the resulting froth is dewatered and then carried away as a pollutant concentrate, and the underflow from the flotation is dewatered and is then carried away as purified soil. An emulsified oily vegetable oil is used as a collector agent for the selective flotation or an emulsified light mineral oil is used as a collector agent for the selective flotation and a light mineral oil is stirred as a conditioning agent into the fine fraction before it is subjected to the selective flotation.

摘要： A process has been developed in order to simultaneously remove the metals and the organic contaminants including pentachlorophenol (PCP) and dioxins and furans (PCDDF) present in contaminated soils and in the effluents emerging from the process. This process including physical and chemical technologies shows a good potential in terms of both inorganic and organic removal performances and economic feasibility. Firstly, the contaminated soils are screened through different sieves and the coarse particles are removed from the fine particles highly contaminated. The coarse fraction (> 0.250 mm) is treated by attrition in the presence of a surfactant. The solid/liquid separation is carried out by wet sieving and the attrition sludge are collected and then treated using a chemical leaching process. The effluents emerging from the attrition steps are collected and treated by flocculation-decantation in order to remove the contaminants and the organic matter. The leaching process developed for the decontamination of the fine particles (

摘要： Cutting wash apparatus includes a wash tank (11) having side walls (15) converging to an inclined lower floor (16) and containing an air agitated wash solution including a surfactant. A cyclone separator (27) receives an oil-based mud and cutting-containing slurry through inlet (30), passing mud to an outlet (31) and a cuttings-rich component to the wash tank (11). A skimmer (13) removes wash overflow and a mud and slurry fines raft floated by the agitation, and passes this to a separator (18). Separated wash liquid is aerated and returned by pump (19) to injection points (28, 29) to recycle wash and provide the agitation. An auger (23) operates in a casing (21) opening into the tank (11) and extending upward of the wash tank and having an upper end discharge outlet (38). Additional aeration and agitation air is injected through air injection bars (45).
