Abstract

The continuous emissions of volatile organic compounds (VOCs) from the industrial process cause serious environmental problems and pose a threat to human health. Photodegradation technology and biofiltration technology are efficient to control VOCs emissions. Recently, the researches on combined photodegradation and biofiltration technology have been attractive, since it could overcome the challenges in the application of the separated technologies, such as toxic by-product emission, excess biomass accumulation, and shock loading. However, no review has published to report the development of the combined technology comprehensively. In this paper, the challenges of the separated photodegradation and biofiltration technology in treating VOCs are documented firstly. Then, the advantages of the combined technology are illustrated by comparing with the separated photodegradation and biofiltration technology, respectively. Finally, the interaction mechanisms between photodegradation and biofiltration are also discussed. The advantages of the combined technology could promote its application in practical engineering.

分离和组合光降解和生物过滤技术处理挥发性有机化合物的比较:批判性综述

摘要

工业过程中挥发性有机化合物 (VOC) 的持续排放会导致严重的环境问题,并对人类健康构成威胁。光降解技术和生物过滤技术可有效控制VOCs排放。最近,光降解和生物过滤联合技术的研究很有吸引力,因为它可以克服分离技术应用中的挑战,如有毒副产物排放、过量生物质积累和冲击载荷。但是,尚未发表评论来全面报告组合技术的发展。本文首先记录了分离式光降解和生物过滤技术在处理 VOCs 中的挑战。然后,通过分别与分离的光降解和生物过滤技术进行比较,说明了组合技术的优势。最后,还讨论了光降解和生物过滤之间的相互作用机制。组合技术的优势可以促进其在实际工程中的应用。
