The impact of heavy metal emissions from municipal solid waste incinerator on its designing operation life

This paper analyses the characteristics of various heavy metal pollution in surface soils surrounded a MSW incinerator located at the coastal areas using fuzzy cluster analysis, Kriging method and field investigation. And the designing operation life estimate of the incineration plant taken into account the national agriculture land use standards had been carried out. The results show that, in the surface soil of the coastal area, the Cr of the soil background structure, which is probably due to the influence of the waste incineration exhaust, is the background value of the downwind 18 times. Pb can be used as an indication of the pollution of exhaust gas, and its source analysis and pollution characteristics indicate that the total pollution in the surrounding area depends mainly on the emission of pollution sources. And the pollution distribution is closely related to the terrain and weather conditions. The use of the ground point source diffusion model and the actual value, to burn the surrounding soil environment for the exhaust of heavy metal pollution receptors, the coastal area incineration plant’s comprehensive environment life is about 29 years.
