title: [Odor emission rate of municipal solid waste from landfill working area].
abstract: Emission rates of volatile organic compounds (VOCs), H2S and odor unit from the surface of a municipal solid waste (MSW) landfill working area were measured with a wind tunnel sampler. The results show that the emission rate of odor from the non-point source of landfill is the function of environmental temperature and surface sweeping velocity. The emission rate measured in the high temperature season can be 6 times higher of that in the low temperature season. Within the experimental range of 0.6-4 m x s(-1) wind sweeping velocity, the emission rate shows a linear relationship with wind sweeping velocity. In summer, the emission rates of VOCs (measured by PID as isobutylene), H2S and odor unit are 385-680 microg x (m(2) x s)(-1), 4-7 microg x (m(2) x s)(-1), and 46.5-136 OU x (m(2) x s)(-1) respectively. The continuous sweeping experiment shows that the emission rate measured with clean air sweeping is the maximum possible emission rate, which needs to be adjusted when it is used to estimate the odor concentration of more than 10 min sample time or an area emission load.
