Abstract: Odour emission from wastewater treatment plants (WWTP) is a common cause of odour nuisance to neighbouring areas. The analysed object was mechanical biological WWTP designed for 1,200,000 population equivalent. Collection of the samples was carried out in accordance with the methodology described in VDI 3880 and PN-EN 13725 during the rainless weather. Odour concentration measurement was made using the method of dynamic olfactometry, in accordance with the procedures described in EN:13725 'Air Quality: Determination of odour concentration by dynamic olfactometry'. For selected emission sources model calculations were conducted using CALPUFF dispersion model for neighbouring residential areas, which are exceptionally exposed to odours. This study presents results of modelling in local scale, for different meteorological scenarios, respectively for winter and summer seasons.
