有机硫恶臭气体治理方法的研究进展

Research Progress of Treatment for Malodorous Organic Sulfur Compounds

恶臭是世界七大环境公害之一,其中具有极臭气味的有机硫气体是恶臭的重要贡献源,其污染控制技术已成为国内外研究的热点。通过介绍国内外当前研究较多的光催化氧化法、低温催化燃烧法、低温等离子体放电法、低温等离子体与其他方法(催化法、吸附法及生物法)的协同机制、活性炭吸附法、生物滴滤法、生物过滤法等各种有机硫气体的治理方法,归纳了它们的作用原理、适用对象及优缺点。随着学科交叉研究的不断深入,固定投入少、运行成本低、处理效率高、资源再生率高、二次污染小将是上述方法技术创新的发展方向。

Odor is one of the seven environmental hazards in the world. The malodorous organic sulfur com pound is an important source of odor and the treatment for organic sulfur has become a hot issue at home and abroad. A comprehensive review is made on the treatment methods of photo catalytic oxidation, catalyzed com bustion, non thermal plasma, the combination mechanism of non thermal plasma and other techniques such as catalysis, adsorption and biology, the adsorption of activated carbon and the purified technology of bi ological filter. The action principles, applicable objects and advantages＆disadvantages of the methods are gen eralized from the cases. With the development of the frontier science, the features of small fixed inputs, low operating cost, high removal efficiency, high resource reuse rate and low secondary pollution will be the inno vative development direction of the methods.
