Abstract

Abstract

Odor dispersion in urban waste transfer stations is the focus of local residents attention. In this study, we numerically simulated the flow fields and odor dispersion around an urban waste transfer station to be constructed, by using computational fluid dynamics methods. The effect of wind speeds and wind directions on the flow and dispersion were investigated in detail. The results showed that normalized flow fields were almost the same, if we changed the wind speeds but kept constant wind direction. Wind speed, however, had great influence on the odor dispersion. The odor dispersed quite quickly at high wind speeds. But the odor dispersed slowly when winds were almost stationary, and it could spread to the building connecting to the waste transfer station and to the southern student accommodation, with the odor concentration three magnitude orders lower than initial one. For east and south wind, we find that the odor dispersed quite quickly, then the affected region was very small. The site selection of the investigated waste station was proved reasonable.
