摘要
阐述了城市生活垃圾焚烧飞灰的物理化学特征,其主要污染物为二噁英类有机物和重金属。为了控制和减少飞灰污染物的含量,介绍了7类飞灰处理技术。对飞灰处理技术的优缺点进行了对比,提出飞灰处理技术的综合应用应契合工艺经济性以及环境亲和性。并对未来飞灰无害化处理作出了展望。
This article describes the physical and chemical characteristics of municipal solid waste incineration fly ash.The main pollutants are dioxins and heavy metals.In order to control and reduce the content of fly ash pollutants,seven types of fly ash treatment technologies are introduced.The advantages and disadvantages of fly ash treatment technology are compared,and it is proposed that the comprehensive application of fly ash treatment technology should be compatible with process economics and environmental compatibility.Finally,prospects for the future harmless treatment of fly ash are made.
