摘　　要：随着垃圾焚烧技术在各个城市生活垃圾处理中的广泛应用,对生活垃圾焚烧的残余物,主要是飞灰的处理、处置,已成为困扰人们生产生活的重要难题之一。飞灰的处理是控制重金属污染的关键,目前处理垃圾焚烧飞灰中重金属污染物的常用方法有:水泥固化法、化学药剂稳定法、飞灰热处理、化学浸提法等,生物淋滤法是近年新兴起来的金属浸提技术。经处理后的飞灰可进行填埋或资源化利用。因此,着重叙述了当前有关垃圾焚烧飞灰中重金属污染的控制方法与处置技术的研究现状。As incineration is increasingly used in the treatment of solid waste（SW） in China nowadays, it becomes a noteworthy problem to dispose fly ash. Treatment of flue gas ash has become the key measure of preventing pollution of heavy metals. This paper introduces the current methods to treat solid wastes abroad such as cement solidification, fly ash thermo - treatment, chemical solidification, chemical lixiviation and so on. Bioleaching is a new method that prevents pollution of heavy metals in recent years. The research status of related control methods and technologies of heavy metals in waste incineration flue gas ash are summarized.
