铅锌冶炼企业二氧化硫烟气泄漏扩散影响浅析

Analysis on the Influence of Sulfur Dioxide Fume Leakage and Diffusion in Lead-Zinc Smelting Enterprises

以我国西北地区某冶炼厂为例,结合企业的工程特征,设定突发环境事件的最坏情景,确定情景源强,采用AFTOX模型预测焙烧炉烟气泄漏环境影响范围,并进行定量预测、评价,对SO 2泄漏采取科学预测,并制定有效的环境风险防控措施,可为铅锌冶炼行业二氧化硫泄漏的环境风险提供参考。

This paper,taking a smelter in northwest China as an example,combined with the engineering characteristics of the enterprise,the worst scenario set emergency environmental accidents,determine the scene source is strong,AFTOX model is adopted to predict environmental impact scope of baking furnace flue gas leakage,and quantitative prediction and evaluation,a scientific prediction on SO 2 leakage and and formulate effective measures of prevention and control of environmental risk for lead and zinc smelting industry sulfur dioxide leak to offer reference to the environmental risk.
