    • An apparatus and method for supplying a vapor-phase nutrient to contaminated soil for in situ bioremediation. The apparatus includes a housing adapted for containing a quantity of the liquid nutrient, a conduit in fluid communication with the interior of the housing, means for causing a gas to flow through the conduit, and means for contacting the gas with the liquid so that a portion thereof evaporates and mixes with the gas. The mixture of gas and nutrient vapor is delivered to the contaminated site via a system of injection and extraction wells configured to the site. The mixture has a partial pressure of vaporized nutrient that is no greater than the vapor pressure of the liquid. If desired, the nutrient and/or the gas may be heated to increase the vapor pressure and the nutrient concentration of the mixture. Preferably, the nutrient is a volatile, substantially nontoxic and nonflammable organic phosphate that is a liquid at environmental temperatures, such as triethyl phosphate or tributyl phosphate.
    • 一种用于向污染土壤供应气相营养物质用于原位生物修复的装置和方法。 该装置包括适于容纳一定数量的液体营养物质的壳体,与壳体内部流体连通的导管,用于使气体流过导管的装置,以及用于使气体与液体接触的装置, 其部分蒸发并与气体混合。 气体和营养蒸气的混合物通过配置到现场的注射和提取井的系统输送到污染部位。 该混合物具有不大于液体的蒸气压的汽化营养物的分压。 如果需要,可以加热营养物和/或气体以增加混合物的蒸气压和营养物浓度。 优选地,营养物是在环境温度下为液体的挥发性,基本上无毒的和不可燃的有机磷酸盐,例如磷酸三乙酯或磷酸三丁酯。
