摘    要:研究了中国垃圾焚烧飞灰中主要重金属在熔融过程的固定化机理,定义了固定率这个参数来表征此过程。采用了中国和美国的危险废物浸出毒性鉴别方法来判别飞灰及其熔融渣的浸出毒性。研究结果表明,固定率能够较好地表征重金属在熔融过程不同温度阶段的固定情况;按照中国和美国废物浸出毒性鉴别标准,飞灰熔融处理后的熔渣不属于危险废物,具备资源化利用的条件。

关 键 词:垃圾焚烧飞灰  重金属  固定率  浸出特性  熔融过程  固化机理  熔渣  浸出毒性  危险废物  资源化利用

Abstract:Solidification mechanism of main heavy metals in MSWI fly ash generated in China during melting process was studied. Solidification ratio was used for justification of the solidification effects. Extraction procedure of China and United States were used to determine characteristic of fly ash and its melting residues. The results showed that solidification ratio could well represent the solidification efficiency of heavy metals in different temperature phases during melting process. According to the Identification Standard for Hazardous Wastes in China and USA, melting residues of fly ash is not classified as hazardous waste.
Keywords:MSWI fly ash Heavy metal Solidification ratio Leaching characteristic
