Abstract:

Considering the complexity of volatile organic compounds (VOCs) treatment technology and the economic benefits in practical engineering applications, this paper introduces the main biological combined technologies, including UV photodegradation and biological process, non-thermal plasma and biological process, chemical and biological process, adsorption and biological process, combustion and biological process, and biological combination technology. The research progress and problems of biological combined technology are summarized. UV photodegradation, non-thermal plasma and chemical method are often used as pretreatment technology combined with biological technology, improving the overall degradation effect and making the bioreactor have better operating performance. The adsorption and the combustion method are usually combined as end treatment technology with biological method to ensure that the exhaust gas can reach the emission standards. In addition, the combination of different biological treatment technologies has formed a synergistic advantage, which makes it obtain better degradation results for industrial waste gas. It is pointed out that biological combined technology is a promising option in waste gas treatment. However, the research of biological combined technology is not deep enough, and its practical application is not mature enough, so it needs to be further explored.

摘要：

考虑到挥发性有机物（VOCs）治理技术的复杂性以及实际工程应用中的经济效益，生物联合治理技术成为了一种研究趋势。本文阐述了目前主要的生物联合治理技术，包括紫外光降解技术-生物法、低温等离子体技术-生物法、化学-生物法、吸附-生物法、燃烧-生物法以及生物法组合工艺。总结了生物联合治理技术的研究进展与存在的问题。紫外光、低温等离子体技术以及化学法常作为预处理技术与生物进行联合应用，在提高整体降解效果的同时也会使生物反应器具有更好的运行性能。吸附法、燃烧法通常作为末端处理技术与生物法进行联合治理，以保障废气可以达标排放。生物组合技术也通过将不同生物治理技术相结合形成协同优势使其对于工业废气取得更优的降解效果。文中指出了生物联合技术在废气治理方面是一个有前景的选择，但生物联合治理技术的研究还不够深入，实际应用也不够成熟，因而需要进行进一步的探究。
