中国石灰工业大气污染物排放标准现状研究

Study on the emission standards of air pollutants for lime industry in China

介绍了中国石灰工业适用的污染物排放国家标准和河北、山东等地方性污染物排放标准,分析了标准规定的基准氧含量值,以及颗粒物、二氧化硫、氮氧化物三种污染物的排放浓度限值水平及变化趋势。结果显示:目前三种污染物的最严限值分别为10 mg/m^3、50 mg/m^3、100 mg/m^3,标准中石灰窑的基准氧含量值集中在8%~10%。石灰工业企业应根据自身条件执行正确的排放标准及政策要求,做好生产管理和环境保护工作。

This paper introduces the existing national and local pollutants emission standards in Hebei,Shandong and other provinces for lime industry in China,and analyzes the reference oxygen content,the emission concentration limits and the change trends of particulate matter,sulfur dioxide and nitrogen oxide.The result shows that the most stringent limits for the above three pollutants are respectively 10 mg/m^3,50 mg/m^3 and 100 mg/m^3,the value of reference oxygen content ranges from 8%to 10%.Based on their own conditions,lime industry enterprises should implement correct emission standards and policy requirements and do a good job in production management and environmental protection.
