摘要
对某制药厂周边区域的SO_2、NO_2和PM2.5三项指标进行监测,对比污染治理前后3年期间的监测结果表明,污染治理效果明显,三项数据由2014年每小时最大超标倍数分别为3.3倍、5.7倍和4.5倍,到治理后2016年分别下降到1.7倍、1.06倍和1.08倍,现各项指标的日平均值已基本达到了空气质量二级标准。针对污染治理成效,分析了影响当地空气质量的因素,并对改善与提高空气质量提出了建议。
Three indicators of SO2,NO2 and PM2.5 in the surrounding area before and after 3 years of pollu- tion control in a pharmaceutical factory were monitored.The maximum multiple times per hour of the three items de- creased from 3.3 times, 5.7 times and 4.5 times in January 2014 to 1.7 times, 1.06 times and 1.08 times in Jan- uary 2016.The daily average of each indicator has basically reached the secondary standard of air quality. In view of the effectiveness of pollution control, the factors influencing the local air quality are analyzed and some sugges- tions are put forward to improve and enhance the air quality.
