为控制和治理汞污染,估算了近年来中国北方某大型竖罐锌冶炼厂冶炼过程中的大气汞排放量.测定了该厂两套生产线的原材料(锌精矿)、焙烧产物(焙砂)及各种炼锌相关产物中(烟尘、烟气净化水、湿尘和硫酸)的汞质量含量、近年来冶炼过程大气汞排放量.运用质量平衡原理,计算出汞在冶炼过程中的质量分布.结果表明:两套生产线大气汞排放因子(生产单位质量的锌向大气排放的汞质量)分别为38g·t-1、30g·t-1.锌冶炼是当地重要的人为汞排放源. |

Mercury emissions from two production lines of a retort Zn smelter in northern China were estimated to estimate the effects of atmospheric pollution prevention and control. The mercury mass concentrations were measured in the Zn concentrate, the calcine, and the other related products (dusts, waste gas cleaning water,wet dust and sulphuric acid). The Hg mass concentration in the feed Zn was calculated for different stages of the smelting process based on the mass balance. The Hg emission factors (defined as Hg emitted to the atmosphere per unit Zn produced) were 38 g·t-1 for the first line and 30 g· t-1 for the second line. Estimates of the mercury emissions from these Zn production lines in recent year show that the Zn smelting is an important anthropogenic Hg source to the local environment. |
