Abstract

An integrated soil vacuum extraction/ biofiltration system has been designed and installed at a gasoline‐contaminated leaking underground storage tank (LUST) site in southern Delaware. The system remediates contaminated moisture entrained in the air stream, employs automatic water level controls in the filters, and achieves maximum vapor extraction and VOC destruction efficiency with an optimum power input. In addition, the valving and piping layout allows the sequence of air flow through the filters to be reversed at given time intervals, which minimizes biofouling, thereby increasing efficiency by decreasing system backpressure. This integrated system achieves VOC destruction rates of up to 69%. The modular design allows for easy mobilization, setup, and demobilization at LUST sites throughout Delaware.

生物过滤与SVE的整合:一个案例研究

在特拉华州南部的一个汽油污染泄漏地下储罐(LUST)现场，设计并安装了一个集成的土壤真空提取/生物过滤系统。该系统可修复气流中被污染的水分，在过滤器中采用自动水位控制，并在最佳功率输入下实现最大的蒸汽提取和VOC破坏效率。此外，阀门和管道布局允许在给定的时间间隔内通过过滤器的气流顺序颠倒，从而最大限度地减少生物污染，从而通过降低系统反压来提高效率。该集成系统可实现高达69%的VOC破坏率。模块化设计允许在整个特拉华州的LUST站点轻松动员，设置和复员。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
