Abstract
|
|
|
In this study, field experiment, odor simulator, and dispersion modeling were used to evaluate the odor impact from J
sewage sludge treatment facility. The height and flow rate of exhaust stack at this facility were 22.3 m and 100 Nm3
/min. The mean odor concentrations of the wet scrubber inlet and exhaust stack were 267±160 and 93±44 OU/m3
, respectively. The odor removal efficiency of wet scrubber showed 65%. The odor simulator is used for the regulated standard calculation of the exhaust pipe(stack). Resulting odor emission rate(OER) by odor simulator was 2.4×106
(24,000 OU/m3). The forecasting result by Screen3 modeling showed that odor exhaust concentration up to 30,000 OU/m3
was’t exceeded maximum allowable emission level on site boundary(15 OU/m3
).
