江苏省PM2.5污染现状分析及建筑室外PM2.5设计质量浓度确定

Analysis of PM2.5 Pollution in Jiangsu Province and Determination of Building Outdoor PM2.5 Design Concentration

根据"中国空气质量在线监测分析平台"发布的2014—2016年的PM2.5监测数据,从空气质量指数、PM2.5日均极大值、年均值及日均质量浓度的分布情况综合分析了江苏省2014—2016年PM2.5污染状况。在统计分析3年的数据的基础上,采用"保证率"的概念,计算并绘制江苏省13个地级市的PM2.5保证率曲线。按此保证率曲线确定的PM2.5室外设计质量浓度,对通风空调系统过滤器设计选型过程有一定的工程实际应用价值。

The concentration data of PM2.5 from 2014 to 2016 is obtained on the ＂China Air Quality Online Monitoring and Analysis Platform＂.The pollution status in Jiangsu area is evaluated and analyzed on the aspects of air quality,daily maximum,annual average concentration and daily average frequency of PM2.5.Based on the research of three years data,＂guarantee rate＂is used to calculate and plot the PM2.5 guarantee rate curve of 13 prefecture-level cities in Jiangsu.The outdoor design concentration of PM2.5 is confirmed by that curve,which has significant engineering reference value for the filter design in air condition system.
