Electrokinetic Transport of Bacteria In Situ for Bioremediation of Ground Water

在许多地下水污染的情况下， 可能是唯一一种既省钱又省时的治疗方法 技术. 然而，成功的治疗可能需要 污染目标中存在具有代谢能力的细菌 区 在没有有利的地下水梯度的情况下， 安装足够的注入和回收装置成为一个问题 威尔斯井以吸取营养物或代谢活性细菌通过 污染区。 电动力学已经被提出作为一种 用于抽取带电污染物的原位处理技术 通过土壤和含水层固体进入回收井。 初步 研究表明，人们可以使用同样的技术， 通过模型含水层定向输送微生物 固体 Envirogen公司建议优化和展示这一点， 三氯乙烯降解菌技术 (TCE、氯乙烯、二氯乙烯及其他有关 污染物从含水层材料的表面。

In many cases of ground water pollution, in situ bioremediation may be the only cost-effective, time-efficient treatment technology. Successful treatment, however, may require the presence of metabolically capable bacteria in the polluted target zone. In the absence of a favorable ground water gradient, the problem becomes one of installing enough injection and recovery wells to draw nutrients or metabolically active bacteria through the contaminated zone. Electrokinetics has been proposed as an in situ treatment technology for drawing charged contaminants through soil and aquifer solids to a recovery well. Preliminary studies have shown that one can use this same technology directionally to transport microorganisms through model aquifer solids. Envirogen Inc. proposes to optimize and demonstrate this technology with bacteria capable of degrading trichloroethylene (TCE, vinyl chloride, dichloroethylene and other related contaminants from the surface of aquifer materials.
