摘要
本文综述了污水处理厂硫化氢(H2S)臭气的主要来源以及浓度范围,然后介绍了生物滤池和生物滴滤池的脱臭机理和工艺,并着重介绍了生物过滤反应器所使用的填料,分析了各类生物脱臭填料在应用中的优缺点以及最近的研究动态。接着介绍了生物过滤系统的主要设计和操作参数,系统地总结了不同生物过滤反应器处理H2S的效果,最后指出了生物过滤系统处理H2S臭气面临的技术挑战和发展方向,包括开发新型填料、改善床层酸化等问题。
This paper reviews the source of hydrogen sulfide （H2S） and its normal concentration in wastewater treatment plants （WWTPs）. And then the removal mechanisms and process of biofilter and biotrickling filters are introduced. It introduced the paeklng materials used in the biofiher and analyzes the advantages and disadvantages of several kinds of packing material. Moreover, it introduces major parameters of design and operation and systematically summarizes the treatment effect of H2S adopting biofilters/ biotrickling filters. Finally, it points out the technical challenges and proposes future development of the biofilter technology for H2S control, including exploitation of novel packing materials and improvement of bed acidification.
