化工固废酸渣鉴别分析

Identification and analysis of high quality of chemical solid waste acid residue

对固废酸渣进行急性毒性鉴别,并对固废酸渣由危险废物转变为非危险废物涉及因素进行探讨。结果表明,硫酸酸渣浸出液砷含量低于标准,由此判定通灵市某化工厂硫酸酸渣为非危险废物。在pH=3.2时浸出液氟含量更高,稳定性好。

The acute toxicity of solid waste acid residue was identified,and the factors involved in the transformation of solid waste acid residue from hazardous waste to non hazardous waste were discussed.The results showed that the arsenic content in the leaching solution of sulfuric acid residue was lower than the standard,so it was judged that the non hazardous waste of sulfuric acid residue was produced in Tongling chemical plant.When pH=3.2,the fluorine content in leaching solution is higher and the stability is better.
