摘要
采用现场调研取样和理化分析检测的方法,对上海市生活垃圾中的重金属含量进行研究,分析了重金属在产生源、物流链以及最终处置环节的变化特征。结果表明:商业垃圾是生活垃圾中重金属的主要产生源;物流过程中重金属含量有所改变;堆肥处理后的垃圾不能直接进行农用;焚烧前的自然干化使重金属富集。
By using on-site sampling and physical-chemical analysis, the contents of heavy metals in Shanghai domestic waste were researched, and the change characteristics of heavy metals from the aspects of sources, logistics chain and final disposal process were analyzed. The result showed that commercial waste was the important source of heavy metal pollution. The contents of heavy metals changed in logistics chain. The product of waste composting could not be used in agriculture directly. And waste natural drying before incineration would increase the contents of heavy metals.
