针对目前钢铁行业大气污染物清单编制和管理过程中存在的问题和需求,利用全国污染源排放在线监测(CEMS)数据、环境影响评价数据、环境统计数据、污染源普查数据等资料,建立了基于生产工艺的全国钢铁行业大气污染物排放清单管理系统,实现了排放清单的动态化管理和编制等功能。以山东省为例,验证了系统清单生成、输出等功能,结果显示2012年山东省钢铁企业SO_2、NO_x、烟粉尘排放量分别为15.23万、18.16万、8.97万t,其中烧结和高炉工艺是主要排污环节;从空间分布来看,莱芜、日照两市的钢铁企业污染排放量最大,SO_2、NO_x、烟粉尘排放量合计占山东省排放总量的50%左右。
Aiming at the existing problems and demands in preparation and management of air pollutants inventory in the steel industry, the author used the CEMS data, environmental impact assessment data, environmental statistics data and census data of pollution sources to establish the production process Of the national steel industry air pollutant emissions inventory management system, to achieve the dynamic inventory management and inventory preparation and other functions. Taking Shandong Province as an example, the functions of system inventory generation and output verification were verified. The results showed that the emissions of SO_2, NO_x and smoke dust in Shandong iron and steel enterprises in 2012 were 152,300, 181,600 and 89,700 tons, respectively. The sintering and blast furnace processes were From the perspective of spatial distribution, the iron and steel enterprises in Laiwu and Rizhao cities have the largest pollution discharges, and SO2, NO_x and smoke dust emissions together account for about 50% of the total discharges of Shandong Province.
