SIMULATION OF ODOUR DISPERSION FROM DA PHUOC LANDFILL

Abstract

The purpose of this research is estimation rate of odorous gas emission from landfills and simulating the odour dispersion. The method used for the study was based on the methane emission model of Intergovermental Panel on Climate change and Gauss Model. The study results showed no discrepancies between calculated and measured data of odorous gas emission, Nash-Sutcliffe coefficient ranged from 0,642 to 0,770. The results of the odour intensity simulations show that there is no significant deviation from the actual data. The difference between the observation and the odor intensity simulation is usually less than one level.
