中文摘要:
      利用2016年6月-9月济南大气污染物连续监测数据和同期的降水数据,分析了夏季降水对大气污染物的清除效果。结果表明,降水对大气污染物的清除效率,最高的是PM10,PM2.5、SO2、NO2次之,对O3的清除效率最低。降水对颗粒物的清除效率高于对气态污染物的清除效率,两者的降水清除机制不同。降水量大于5 mm时,降水对污染物有一定的清除效果,且清除效果随雨量增大而增大。降水时长为10~15 h时,降水事件对大气污染物的清除效率最高。
英文摘要:
      The continuous monitoring data of air pollutants and precipitation data in Jinan from June to September in 2016 were used to analyze the effect of summer precipitation on air pollutants removal. Results showed that precipitation had the highest removal efficiencies on PM10, followed by PM2.5, SO2 and NO2, while it had the lowest removal efficiency on O3. The removal efficiency of precipitation on particulate matter was higher than that on gaseous pollutants due to differences in precipitation system. When precipitation was greater than 5 mm, it had a certain removal effect on pollutants, and the removal efficiency increased with the amount of rainfall. When precipitation last for 10~15 h, it had the highest removal efficiency on air pollutants.
