| 摘 要： | 生活垃圾焚烧炉渣富集了大量重金属，对环境有严重影响。对生活垃圾焚烧炉渣以（ HJ／T 299－2007）硫酸硝酸法浸提，在不同的pH浸提条件下对炉渣中重金属浸出特性进行了实验研究。结果表明重金属浸出量随着浸出pH的下降有明显上升趋势，尤其在酸性条件下有明显提升。炉渣在酸雨长期浸泡下会浸出大量重金属，对周边土壤及地下水造成严重影响。

| Abstract: | A lot of heavy metals enriched in domestic garbage slag .A sequential of domestic garbage slag leaching experi-ments was proposed according to HJ/T 299-2007 Sulfuric acid nitric& acid method .Leaching tests of heavy metals in different pH was studied in this research.The results showed that heavy metals concentration increased with the decreasing pH leaching condition,especially in acidic condition.With the extension of leaching time in acid rain, more heavy metals were leached, and it will have a persistent serious effect on soil and groundwater. |
