Reducing Secondary Environmental Risk from Municipal Solid Waste Incineration
During incineration of municipal solid waste (MSW),various environmentally harmful elements and heavy metals are liberated partly into bottom ash,and partly carried away with the off-gases and subsequently trapped in fly-ash.If these waste incineration residues are not properly processed and immobilized,it can lead to secondary environmental pollution to the air,soil and water.The stricter environmental regulations require a higher immobilization efficiency of the waste incineration residues,which is the main objective of the present cooperation research.Within the present project,a systematic scientific research on various MSWI residues has been carried out,including sampling,low or high temperature processing and leaching tests.In the present paper,the major results have been summarized.The research results reveal that through appropriate combined pre-processing and high temperature vitrification,the bottom ash and fly ash can be efficiently stabilized.The results achieved provide a valuable alternative route to treat the solid residues from incinerators,and to make efficient recycling and safe utilization possible.
