对上海、山东、四川地区的6家生活垃圾焚烧厂飞灰重金属特性进行了分析，结果表明：飞灰中重金属主要以硫酸盐和氯化物形式存在，含量较高的元素是 Zn、 Pb、 Ba、 Cu，含有量随地域和季节有一定波动。对6家焚烧厂飞灰采用醋酸缓冲溶液法（HJ/T 300—2007）做浸出实验发现浸出浓度易超标的重金属主要是 Cd 和 Pb，进一步通过Tessier 法研究飞灰中 Pb 的化学形态，发现其潜在浸出能力和生物可利用性非常大，在飞灰稳定化处理中需特别关注。

The characteristics of heavy metals in fly ash from 6 domestic waste incineration plants in Shanghai, Shandong and Sichuan were discussed. The results show that the heavy metals in fly ash are mainly in the form of sulfate and chloride. Zn, Pb, Ba and Cu takes a higher proportion and the proportion differs in accordance with regions and seasons. After leaching exper-iment with acetic acid buffer solution method (HJ/T 300—2007) on the fly ash from 6 domestic waste incineration plants, it’s found that the leaching concentration of Cd and Pb would easily exceed the standard level. The elemental speciation analysis of Pb in fly ash with Tessier method shows a considerable potential leaching ability and bioavailability, and hence should get more attention in stabilizing treatment of fly ash.
