Design and Application of Biofilter to Control Odor in Wastewater Treatment Plant

摘要

The biofilter was introduced to control odor gas in wastewater treatment plant through the analysis to the characteristics of odor gas and the process of biological deodorization.The collection and transportation of odorous gas and the operations of the odor control systems were described in detail. The running practice indicated that the process has steady and reliable treatment effect, and the pollutants can meet the requirement of the secondary standard of discharge standard of pollutants for municipal wastewater treatment plant (GB 18918-2002) in China.
