Abstract
|
|
|
Odor from sewage treatment plants have the potential to cause significant annoyance and to impact the amenity. In this
study, odor emission characteristics at unit process of 48 sewage treatment facilities in 39 plants were evaluated using
composite odor concentration and hydrogen sulfide (H2S) concentration. The values of composite odor concentration
(geometry mean) and H2S concentration (median) for sludge treatment processes are higher than those for the other treatment processes. The composite odor concentration and H2S concentration are distributed over a wide area in each process.
Composite odor concentration (dilution ratio) was found to have the significant correlation with H2S concentration
(p=0.000<0.05). The H2S concentration accounted for 67.1% of composite odor concentration.
