Abstract
In this study, the major emission procedures and emission characteristics were identified atthe site of sewage treatment plant which is one of the major sources of ammonia. At the sametime the emission factors and emission rates were estimated. In order to calculate the emissionflux, we used a Dynamic Flux Chamber(DFC), which is found to be a proper sampling devisefor area sources such as sewage treatment plant.It was found that the most stable sampling condition was when the stirrer’s speed of DFCwas 120RPM, and it would be the best time to take a sample 60 minutes later after setting thechamber.The relatively higher flux was shown in Autumn compared to summer and winter.Annual ammonia emission rates procedures were calculated as 906.32 mg/activity-ton,1,114.72 mg/activity-ton and 437.53 mg/activity-ton each at the primary settling basin, aerationbasin and the final settling basin, respectively. The ammonia emission rate the highest at in theaeration basin according to this test. This results was due to that the surface of aeration basin orthe final settling basin is relatively wider than the primary settling basin.
