Evaluation Method of Odor Pollution in Urban Sewage Treatment Plants Based on Electronic Nose Technology

摘要

In order to track the odor source and odor fingerprint characteristics of the sewage treatment plant, this studymakes quantitative analysis and evaluation. Based on the advantages of odor sensory evaluation and odorsource identification of electronic nose technology, this study focuses on the odor pollution of urban sewagetreatment plants. This study firstly introduces the principle and application of electronic nose technology, thentakes an urban sewage treatment plant in Wuhan as the sampling point and the (Malodorous Volatile OrganicCompounds (MVOCs) in the odor pollution as the research object; evaluates the fingerprint characteristics ofsingle component in MVOCs with electronic nose sensor, and tests the quantitative evaluation relationship ofodor. Finally, the contributions of each pollution source to the odor concentration in each sewage treatmentplant are analyzed through forecasting the odor in the surrounding environment. The theoretical research andpractical application of electronic nose technology in odor evaluation has a forward-looking guidingsignificance for odor detection and management of sewage treatment plants in the future.
