摘　　要：生物通风法作为物理处理方法与生物处理方法相结合的一种土壤原位修复方法,因具有高效、处理费用和尾气处理成本低等特点而对挥发性有机物(Volatile Organic Compounds)污染土壤的治理具有广阔的应用前景。本文概述了生物通风系统的原理、适用范围、优点,并对生物通风的国内外研究现状进行了阐述,包括现场应用、实验室研究、模型模拟研究(非生物过程和生物降解过程模拟)及影响因素(土壤理化性状、污染物因素及微生物因素),提出了生物通风技术存在的问题及需要作的进一步研究。Bio-venting is an in-situ remediation technique combined with physical treatment and biological treatment for volatile organic compounds polluted soils.It has broad application prospects in soil contamination caused by volatile organic compounds due to its high-performance,low treatment cost and tail gas treatment cost.In this paper,the principle,applied range,advantages,studies of bio-venting in home and abroad were summarized,including the applications in fields,laboratory research,simulation study（non-biological process and biodegradation process simulation）,effect factors（the physical and chemical characteristics of the soil,contamination concentrations and microorganisms）.In addition,the problems and the further research about bio-venting were raised.
