【摘要】：采用情景分析的方法,建立了不同情景下中国有色金属冶炼行业的汞排放趋势,并分析了主要控制措施对该行业大气汞减排的贡献.研究发现,中国有色金属冶炼行业2030年的最大减排潜力将达到122.3t,比2012年降低82.9%.其中,锌、铅和铜冶炼的大气汞排放量将分别减少77.8t、42.7t和1.8t.为减少大气汞排放,锌冶炼将主要通过完善大气污染控制措施实现.其中2020年和2030年采用该措施将分别减少51.0t和23.9t的大气汞排放量.铜冶炼主要通过增加再生铜比例实现大气汞减排.2020年和2030年,该措施大气汞减排量分别占铜冶炼总减排量的61.1%和72.5%.2020年前,铅冶炼的大气汞减排主要通过淘汰落后产能和完善协同控制设备实现,将贡献88.8%的总减排量.2020~2030年,铅冶炼通过增加再生铅比例贡献65.3%的总减排量.
[Abstract]:Using scenario analysis method, the mercury emission trends of China's non-ferrous metal smelting industry under different scenarios are established, and the contribution of main control measures to atmospheric mercury emission reduction in this industry is analyzed. In 2030, the maximum emission reduction potential of China's non-ferrous metal smelting industry will reach 122.3 t, which is 82.9 t lower than 2012. Among these, atmospheric mercury emissions from zinc, lead and copper smelting will be reduced by 77.8 t / t 42.7 t and 1.8 t respectively. Zinc smelting will mainly be achieved by improving air pollution control measures. In 2020 and 2030, the atmospheric mercury emissions will be reduced by 51.0 t and 23.9t respectively. Copper smelting will achieve atmospheric mercury emission reduction mainly by increasing the proportion of recycled copper. Before 61.1% and 72.5.2020 of the total reduction of atmospheric mercury in copper smelting, the reduction of atmospheric mercury in lead smelting was mainly realized by eliminating backward production capacity and perfecting cooperative control equipment, and the total emission reduction of 88.8% would be achieved from 20 to 2030. Lead smelting contributes 65.3% of the total emission reduction by increasing the proportion of recycled lead.
