The property of municipal solid waste incineration(MSWI) fly ash from Shanghai

MSWI fly ash is a new problem in development of new municipal solid waste incineration technology. Fly ash contains a high degree of toxic substance and must be disposed safely. The property of fly ash is very important to how to dispose it and disposal effect. The property of fly ash is very different in different clime. We detected some property of fly ash from S.H. Yuqiao municipal solid waste incinerators, such as chemical composition, leachability of heavy metals, volatility of heavy metals, etc.and then analysed the results. The results indicate: There was a high degree of SiO 2 in fly ash from Shanghai. So it is propitious to vitrification. But we must also notice that volatility of heavy metals is very high in course of vitrification.
