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/m3,50 mg/m3 and 100 mg/m3, 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.
