生物滤池去除污水处理厂臭气的应用及展望

污水处理厂中恶臭气体污染已成为环境污染的重大问题，除臭技术的研究与应用已经成为一个热点。生物除臭法利用微生物的代谢作用转化致臭物质，不会产生二次污染，适于处理污水处理厂的臭气。生物滤池除臭技术在污水处理厂中应用广泛。介绍了污水处理厂恶臭物质的成分、来源及生物滤池工艺的概况，详细阐述了生物滤池的影响因素，与其他除臭工艺的比较以及最近几年的工程实例，最后概述了生物滤池工艺存在的问题以及发展方向。

Application and prospects of the biofilter for the removal of malodors in wastewater treatment plant

The malodor pollution has already become a very important problem of environmental pollution in the wastewater treatment plant and the study and application of deodorization technology have already become a focus. Biological deodorization method uses microbial metabolism to transform malodorous substances without secondary pollution, so it is suitable to deal with the malodor from wastewater treatment plants. The biofiher technology is widely used to control the malodor in wastewater treatment plant. The paper introduces the components and source of malodors and the overview of biofiher process and elaborates the influencing factors of the biofiher. At last, it summarizes the existing problems and development direction of biofilter technology by comparing with other deodorization technology and engineering practice in recent years.
