    摘要： A method of removing organic contaminants from an aqueous composition contaminated therewith. The method comprises contacting the aqueous composition with a sufficient amount of organoclay for a sufficient amount of time to absorb a substantial portion of the contaminant, and to form an aqueous organoclay admixture. The organoclay and aqueous composition are then separated from each other. The method is particularly useful for separating oily contaminants from water toxic substance precursors, e.g. humic acid and toxic organics (e.g. PCB) from water.

    摘要： Procédé de traitement de compositions de fluides aqueux ou polaires contenant une quantité de contaminants organiques dans le but d'immobiliser le contaminant en formant une matrice non-coulable contenant le contaminant. La matrice non-coulable peut être facilement éliminée. Le procédé consiste à ajouter une quantité suffisante d'organo-argile à la composition fluide pour absorber sensiblement toute la substance contaminante organique. Une quantité suffisante d'adsorbants solides est ajoutée à la composition pour absorber ou réagir avec sensiblement la totalité du fluide polaire ou de l'eau pour former une matrice sensiblement non-coulable. D'une manière typique, de tels fluides polaires ou compositions aqueuses sont sous forme d'émulsions avec le contaminant organique, et l'adjonction des organo-argiles détruit l'émulsion, permettant l'extraction d'une partie de l'eau ou du fluide polaire de la composition pour réduire ainsi le volume à éliminer. Le procédé de la présente invention immobilise le contaminant organique de sorte qu'il ne peut pas suinter de la matrice.

    摘要： The invention relates to a refuse landfill impervious system capable of prolonging breakdown time of leachate and a manufacturing method thereof. The system comprises a leachate collection and drainage layer, a first HDPE (high-density polyethylene) geomembrane impervious layer, a clay layer and a groundwater collection and drainage layer which are sequentially stacked from top to bottom. The clay layer is composed of a lower clay layer, a middle clay layer and an upper clay layer which are sequentially arranged, wherein the middle clay layer is filled with a medium-fine sand layer laid with sands of particle sizes ranging from 0.1 mm to 0.5 mm and of water contents ≤ 3%, wherein the saturated permeability coefficient of the medium-fine sand layer varies from 1×10 -5 to 1×10 -3 cm/s. Therefore, breakdown time of the leachate can be greatly prolonged, and the imperious effects of a refuse landfill impervious layer can be enhanced; meanwhile, the medium-fine sands are readily available as they are low in cost and widely spread in China. The refuse landfill impervious system capable of prolonging breakdown time of the leachate has a simple structure and is able to effectively prevent the groundwater from permeating in order to saturate the medium-fine sand layer, keeping the medium-fine sand layer in an unsaturated state all the time.
