Bioremediation Through Enhancement of Soil Microbial Populations

这个小企业创新研究第一阶段项目将通过使用创新的电化学增强土壤微环境，为改善生物修复工作提供技术基础。原位工程生物修复可用于快速、更经济地减少或破坏底土中的有机污染物，并且与目前可用的其他去污方法相比，对环境运行的干扰较小。工程生物修复中最大的问题是缺乏污染物降解微生物。该提案描述了一项研究，该研究将证明一种新的原位电化学系统的可行性，该系统将增强土壤微生物种群，从而促进有机污染物的更有效降解。这种方法的优点包括：（1）污染物降解发生在地下环境中;（2）化学添加剂成本低且对环境无害;（3）场地净化的资本成本相对较低。第一阶段的实验将使用实验室规模的系统进行，包含不同成分和特性的天然土壤。

This Small Business Innovation Research Phase I project will provide a technical foundation for the improvement of bioremediation efforts through the use of innovative electrochemical enhancement of the soil microenvironment. In situ engineered bioremediation can be used to reduce or destroy organic contaminants in subsoils quickly, more economically, and with less disruption of operation of the environment than other decontamination methods currently available. The great concern in engineered bioremediation is the absence of contaminant degrading microbes. This proposal describes research that will demonstrate the feasibility of a new in situ electrochemical system that will enhance the soil microbial population thus promoting the more efficient degradation of organic contaminants. Advantages offered by this approach include: (1) contaminant degradation occurs in the subsurface environment; (2) the chemical additives are low cost and environmentally benign; and (3) relatively low capital cost for decontamination of site. Phase I experiments will be conducted using bench scale systems, containing natural soils of varying compositions and characteristics.
