Method and system for digesting heavy metal in solid wastes with high organic matter content

The invention provides a method and a system for digesting heavy metals in solid wastes with high organic matter content, and the method comprises the following steps: adding hydrogen peroxide into the solid wastes for heating treatment, and then digesting the heavy metals. According to the technical scheme, after hydrogen peroxide is added, organic matter interference is removed through heating, the digestion process of heavy metal in the solid waste with the high organic matter content is safer, and the problem that digestion fails or liquid splashing is likely to happen due to gas expansion is solved; and meanwhile, the digestion is more complete, and low detection data caused by incomplete understanding is avoided. 本发明提供了一种有机物含量高的固体废物中重金属的消解方法及系统，所述方法向固体废物中加入双氧水加热处理，随后进行重金属的消解。本发明技术方案加入双氧水后加热去除有机物干扰，使有机物含量高的固体废物中重金属的消解过程更安全，避免了发生气体膨胀导致消解失败或容易发生液体喷溅的问题；同时消解更完全，避免了解不完全导致检测数据偏低。
