【摘要】：以钢铁环境统计数据为基础,分析了2012年钢铁行业二氧化硫、氮氧化物、烟粉尘、二氧化碳等排放情况;基于发达国家钢铁产业结构现状,建立了未来我国工业化后的钢铁产业结构优化调整情景,分析钢铁行业大气污染物减排情况。经计算,2012年中国钢铁企业排放二氧化硫、氮氧化物、烟粉尘、二氧化碳分别为191.88万,51.84万,59.14万,15.04亿t,河北省二氧化硫、氮氧化物、烟粉尘、二氧化碳排放量最大,分别占全国总排放量的22.59%、30.35%、35.54%、25.19%;预测产业结构调整后,中国钢铁行业排放二氧化硫、氮氧化物、烟粉尘、二氧化碳排放量分别为16.8万,18.9万,13.86万,6.62亿t,与2012年现状情景相比,分别减少91.24%、63.54%、76.56%、55.98%。
[Abstract]:Based on the statistical data of iron and steel environment, this paper analyzes the emission of sulfur dioxide, nitrogen oxide, smoke dust and carbon dioxide in the iron and steel industry in 2012, and based on the present situation of iron and steel industry structure in developed countries, The situation of optimizing and adjusting the structure of iron and steel industry after industrialization in the future is established and the emission reduction of atmospheric pollutants in iron and steel industry is analyzed. It has been calculated that in 2012, Chinese iron and steel enterprises emitted 1.9188 million, 518400, 591400, 1.504 billion tons of sulphur dioxide, nitrogen oxide, smoke dust and carbon dioxide respectively. Hebei Province has the largest emissions of sulfur dioxide, nitrogen oxide, smoke dust and carbon dioxide. After the adjustment of the industrial structure, the iron and steel industry in China discharged 168000, 189000, 138600 and 662 million tons of sulphur dioxide, nitrogen oxide, smoke dust and carbon dioxide, respectively, which decreased respectively by 91.240.63.54 and 76.5655.98, compared with the current situation in 2012.
