Sewage Sludge Management Program. Volume 3B: Odor Studies, 1975-1977. Development of Odor Criteria for Large Emission Areas

摘要

The objective of this study was to develop odor criteria for solids storage basins (SSB) which are now being incorporated into a new 136-mgd regional wastewater treatment plant. The study establishes the relationship between SSB surface odor emission rates and total emission rates for large areas and documents the close relationship between micrometeorological conditions in the vicinity of large emission areas and the dispersion rates which govern the transport of odors from these areas to downwind locations. Frequency distribution curves are developed for SSB downwind dispersion coefficients under strong inversion conditions and SSB surface odor emission rates. These curves are then used to estimate the probable 'at least' and 'at most' frequency of downwind (property line) odor concentrations.
