硫铁矿制硫酸中部分重金属相关问题的探讨

Discussion on Some Heavy Metal Related Issues in Sulfuric Acid Production from Pyrite

文章分析以硫铁矿为原料制取工业硫酸的过程中,重金属元素(镉、汞、砷、铅、铬、铜、镍、锌、铊)的来源,及其在硫酸生产工艺中的物理、化学变化和最终去向,梳理国家在硫酸行业原料、产品及污染物排放标准中对重金属污染物指标的监控情况,讨论硫酸行业如何应对日益严苛的重金属排放控制要求,实现绿色健康发展。

The analysis of pyrite as raw material in the process ofindustrial sulfuric acid,heavy metals(cadmium,mercury,arsenic,lead,chromium,copper,nickel,zinc,thallium) source,and the physical and chemical changes and eventually,combing countries in sulfuric acid industry raw materials,products and pollutant emission standards in the monitoring of heavy metal pollutants indicators,discuss sulfuric acid industry how to deal with increasingly stringent heavy metal emission control requirements,and realize the green healthy development.
