A unique type of waste--air pollution control (APC) residues--has received increasing attention in China since the first large-scale incinerator, Shanghai Yuqiao municipal solid waste (MSW) incineration plant, was installed in the country in 2002. The APC residues of this particular plant are similar to other residues that will be produced in other incineration plants under construction in China. This work examines for the first time the benchmark contaminants of APC residues from the Yuqiao Plant, with reference to soluble salts, heavy metals and dioxins. Experimental findings reveal that the residues contained a marked amount of soluble salts, of up to 17.4-21.9% (mostly chlorides), 0.98-1.5 ngTEQ/gash of dioxins and various heavy metals. Lead is of particular concern, and requires stabilization before disposal. Heavy metal speciation schemes were implemented herein to determine the leaching characteristics. The correlation between the amounts of soluble salts or chemical speciation of the heavy metals and the leaching toxicity of these heavy metals in the residues is considered.
自2002年中国首座大型焚烧炉——上海御桥生活垃圾焚烧厂建成以来，一种独特的废弃物——大气污染控制（APC）残渣在中国受到了越来越多的关注。该特定工厂的APC残渣与中国其他在建焚烧厂产生的其他残渣相似。这项工作首次参照可溶性盐、重金属和二噁英，对御桥工厂APC残渣的基准污染物进行了研究。实验结果表明，这些残渣含有大量可溶性盐，含量高达17.4% - 21.9%（主要是氯化物），二噁英含量为0.98 - 1.5 ngTEQ/g灰，以及各种重金属。铅尤其值得关注，在处置前需要进行稳定化处理。本文采用重金属形态分析方案来确定浸出特性。考虑了残渣中可溶性盐的含量或重金属的化学形态与这些重金属浸出毒性之间的相关性。
