摘要

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。

Integrating biofiltration with SVE: A case study

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.

期刊介绍： When it comes to assessing and mitigating contaminated soils and sediments, there is no substitute for having the very latest tools, techniques and methodologies at your fingertips to help you deal with these issues efficiently and cost-effectively. This is just the kind of essential expertise you’ll only find in Soil and Sediment Contamination . This internationally, peer-reviewed publication focuses on soil and sediment contamination from: -Sludges- Petroleum- Petrochemicals- Chlorinated hydrocarbons- Pesticides- Lead and other heavy metals. Get detailed descriptions of all the latest and most efficient offsite and in situ remediation techniques, strategies for assessing health effects and hazards, and tips for dealing with everyday regulatory and legal issues. With the state-of-the-art tools that Soil and Sediment Contamination provides, you can successfully assess, mitigate, and solve both rural and urban soil contamination problems as efficiently and economically as possible.
