摘要: Successful bioremediation of contaminated soils is controlled by the ability to deliver additives, such as bacteria and/or nutrients, zone. Because hydraulic advection not practical for delivery in clays, electrokinetic (EK) injection an alternative efficient and uniform additive into low-permeability soil heterogeneous deposits. EK-enhanced bioaugmentation remediation clays with chlorinated solvents evaluated. Dehalococcoides (Dhc) bacterial strain lactate ions are uniformly injected clay complete dechlorination ethene observed laboratory experiments. The can survive, grow, promote effective under EK conditions after application. distribution Dhc within suggests that transport primarily driven electroosmosis. In addition biodegradation due Dhc, EK-driven ethenes clay, which accelerates cleanup from anode side. Compared conventional advection-based delivery, significantly more establishing microbial reductive capacity soils.
