网格化微型空气质量监测系统可行性研究

FEASIBILITY STUDY OF A GRIDDED MINIATURE AIR QUALITY MONITORING SYSTEM

为验证网格化微型空气质量监测系统(以下简称微站系统)可行性,于2021-10-01—20对西安高新区微站系统日均值浓度监测数据偏差进行系统评估。结果表明:高新西区国控站周围微站系统CO、NO_(2)、SO_(2)、O_(3)、PM_(2.5)及PM_(10)6类污染因子日均值平均浓度监测偏差程度基本满足±10%以内的要求。草堂基地省控制站、五星街办及兴隆街办省控站周围微站系统6类污染因子日均值平均浓度监测偏差程度基本满足±10%左右的要求。值得注意的是,环境空气湿度较大,可能会对微站系统监测结果产生一定影响,但整体仍在可控范围内,综上所述,网格化微型空气质量监测系统用于空气质量监测是可行的。

In order to verify the feasibility of the gridded micro-air quality monitoring system(hereinafter referred to as the micro-station system),the deviation of the daily average concentration monitoring data of the micro-station system in Xi’an High-tech Zone was systematically evaluated on 2021-10-01-10-20.The results show that the degree of deviation from the average concentration of the daily average concentration of six types of pollution factors,such as CO,NO_(2),SO_(2),O_(3),PM_(2.5)and PM_(10),around the state control station in the high-tech west district basically meets the requirements of±within 10%.The degree of deviation from the monitoring deviation of the average daily concentration of the six types of pollution factors in the micro-station system around the provincial control station of Caotang Base,the Five Star Street Office and the Xinglong Street Office basically meets the requirements of about 10%of the±.It is worth noting that the ambient air humidity is large,which may have a certain impact on the monitoring results of the micro-station system,but the overall is still within the controllable range,in summary,the grid micro air quality monitoring system is feasible for air quality monitoring.
