基于在线监测数据的青奥会废气重点污染源临时管控效果评估

Assessing the Effects of Temporary Control of the Major Waste Gas Sources during the Youth Olympic Games Based on the Online Monitoring Data

简述了南京市废气重点污染源在线监测系统的组成和工作原理。根据2014年南京青奥会废气重点污染源环境临时管控要求,利用在线监控点位对7月份(青奥会前)和8月份(青奥会期间)重点废气污染源在线监测数据进行了统计分析。结果表明,青奥会期间南京市管控废气重点污染源的SO2和NOX排放量虽有个别企业出现增加,但整体排放量均有所降低,环境空气中SO2和NOX的平均值也有所降低,基本达到了临时管控要求。

This paper briefly introduces the online monitoring system for major waste gas sources in Nanjing. In order to ensure the environmental air quality meet the requirements during the 2014 Youth Olympic Games （YOG） , some temporary control measures were adopted for monitoring major waste gas sources. The online monitoring data from major waste gas sources in June （before YOG） and August （during YOG） was statistically analyzed using the current online monitoring spots. The results showed that al- though a few of the waste gas sources had increased SO2 and NOx waste gas emission during the YOG period, general waste gas e- mission was decreased. The average value of SO2 and NOx in ambient air was also decreased, which basically met the requirements of the temporary control.
