Assessment of Odour Impacts of the Proposed Municipal Solid Waste Incinerating Plant

Odour gases are typical air pollutants emitted from municipal solid waste incinerators (MSWI). Concerns over their adverse health effects, the stringent emission limits for odour gases were constituted. The odour emission should be assessment before a MSWI be constructed. In this case study, according to analogy analyse, the odour gases H₂S and NH₃ are 0.036kg/h and 1.298kg/h, respectively. With strictly odour gases control system in garbage storage, transportation and incineration processes, the simulative calculated odour gases emission concentration lower than the limited values in Emission Standards for Odour Compounds. The calculated maximum ground concentration of H₂S and NH₃ are 0.0001mg/m³ and 0.0039mg/m³, respectively. The calculated distance of max ground concentration to the stack lower than the limited values in Hygienic standards for the Design of Industrial Enterprises (GBZ1-2002), are 591m and 594m, respectively. The modified calculate hygienic protection distance is 400m.
