VOCs污染场地SVE修复系统尾气净化技术研究进展

Review on SVE System Exhaust Treatment Technology for VOCs Polluted Sites Remediation

摘要: 土壤气相抽提技术（SVE）日益受到人们的重视，SVE尾气的主要成分是危害性大的挥发性有机物（VOCs），目前国内外针对净化技术的进展报道较少。传统上一般采用燃烧、吸附、冷凝和吸收等方法处理VOCs废气，对比现有VOCs废气处理技术，综合分析发现生物法性能优良，对VOCs净化效果好且无二次污染，相对于其他方法更适用于SVE系统尾气的净化，可在完成尾气中VOCs有效净化的同时，解决现有SVE系统尾气净化装置填料后处理问题，是很具研究价值的尾气中VOCs净化方法。

Abstract: Nowadays，people pay more and more attention to soil vapour extraction technology（SVE）.The main component of SVE exhaust is volatile organic compounds（VOCs）and related purification technology research is needed in China.Conventional VOCs control technologies mainly include incineration，condensation，adsorption and absorption technologies.It has been found that biofilter was a promising method to purify SVE exhaust with good performance，effectively VOCs purification effect and save secondary pollution.It is more suitable to purify SVE system exhaust compared with other methods.
