odour nuisance - Opis:
- Odour emission from Wastewater Treatment Plants (WWTP) is a common cause of odour nuisance to neighbouring areas and passive area sources such as primary clarifiers or sludge thickeners are the main objects contributing to odour nuisance of WWTP. Due to the peculiar character of those sources, odour emission from them can vary significantly depending on number of factors such as pH, temperature of sewage, wind velocity, BOD or COD load. Because of that, while estimating odour impact range of passive area sources by dispersion modelling it must be taken into consideration when odour emission data has been collected. This paper focuses on determining odour impact range of WWTP primary clarifiers for two various emission cases – maximum and minimum emission determined during 7 months of study. Maximum emission was observed during summer (August) and minimum one in winter season (February).The analysed object was mechanical biological wastewater treatment with full sludge treatment designed to collect sewage from one of the major polish cities.Collection of odour samples was carried out in accordance with the methodology described in VDI 3880 and PN-EN 13725. 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 Gasussian dispersion model for neighboring areas, which are exceptionally exposed to odours. Calculations showed big differences in odor impact range for two analysed emission scenarios – odour impact range calculated using emission data from August is almost two times greater than for calculations using emission data from February.
