Sewage Sludge Management Program. Volume 3A: Odor Studies, 1975-1977. Diurnal Odor Evaluations at the Solid Storage Basins

摘要

Volume 3A of the Sacramento Regional County Sanitation District's Sewage Sludge Management Program contains two reports. The first report, 'Diurnal Odor Evaluations at the Solids Storage Basin,' concluded that the occurrence of high solid storage basins (SSB) surface odor emissions was related to thermal stratification, thermal mixing, and coalescence and volatilization of immiscible odorants. The second report, 'SSB Source Odor Control Study,' found that (1) vacuum vaporization is the most effective method of removing odors from liquid anaerobically digested sludge, (2) activated carbon adsorption provides the most effective means of removing the resultant odorants from the vaporization system exhaust, and (3) effective digested sludge odor control reduces SSB surface odor emissions rates by approximately 50 percent.
