Safe Analysis of Construction Material after Being Sintered

Abstract:

In this work, leaching toxicity of MSWI (municipal solid waste incineration) fly ash by HVEP (horizontal vibration extraction procedure) and ALT (available leaching toxicity) as a function of temperature was analyzed. MSWI fly ash was firstly sintered at 700°C, 800°C, 900°C, 1,000°C and 1,100°C respectively for 30 minutes, and then underwent leaching toxicity analysis of heavy metals. It was found that leaching toxicity of the heavymetals in fly ash sintered at temperatures over 900°C is lower than the limit value described in Identification Standard of Hazardous WasteIdentification of Leaching Toxicity. Therefore, 1000°C is recommended to treat MSWI fly ash.
