淘汰落后产能可以显著降低由工业热过程排放的非故意产生类持久性有机物染物. 对该类政策带来的二(左口右恶)英类污染物减排进行估算可以客观评价我国在履行《关于持久性有机污染物的斯德哥尔摩公约》所做出的努力和贡献. 作者曾对2006~2010年间淘汰落后产能政策的减排影响作过分析,本研究拟在此基础上根据我国2010~2013年关停的落后产能情况,估算得出电力行业、 焦炭行业和钢铁行业(含铁合金)由于关闭落后产能累计带来的二(左口右恶)英类向大气减排(以I-TEQ计,下同)分别约86.13、 133.94和78.78 g·a~(-1). 除了上述提到的重点工业部门,关闭落后产能涉及到的水泥、 电石、 金属冶炼、 造纸等行业也会由于政策的实施而减少二(左口右恶)英类的排放,该研究为以后进行全面评估提供了思路和方法支持. |

Phase-out of backward production facilities can significantly reduce the emissions of unintentional persistent organic pollutants from the industrial thermal process. An estimation of reduced dioxin emissions due to closure of backward production capacities is valuable to objectively evaluate China's efforts in and contribution to performing the Stockholm Convention on Persistent Organic Pollutants. Our group previously evaluated environmental effects of the phase-out of backward production facilities on dioxin emissions from 2006 to 2009. Based on the above study, due to the phase-out of backward production capacities from 2010 to 2013, the reductions in dioxin emissions to air from power generation sector, coke sector, and iron & steel (including ferroalloy) sector were estimated to be 86.13, 133.94 and 78.78 g·a~(-1), respectively. Because the emission factors used in this paper are a little bit conservative, the actual reduced emissions may be greater than the estimated values. Besides the industrial sectors mentioned above, reduced dioxin emissions can also be estimated in more industrial sectors such as cement, calcium carbide, metal smelting and papermaking sectors. The paper also provided methods for the future comprehensive evaluation of dioxin reduction. |
