摘　　要：传统污染源颗粒物监测方法虽保证了质量但耗时过长;而快速检测方法多以间接测量为主,测量信号与质量浓度量的对应关系无法现场进行校核。基于便携式振荡天平法采用标准膜重量直接验证方式解决了设备性能无法现场核查的难题,无需重新建立测量信号与质量浓度量的对应关系。研究表明:在水平振动为56.2~94.4 dB,垂直振动为58.4~96.5 dB条件下,测试前、后振荡天平称量值与标准滤膜定值的相对误差均不大于±3.5%,标准偏差均小于0.5%。该研究为固定污染废气颗粒物的现场快速监测提供了有效的质量保证。The traditional monitoring method of particulate matter from pollution source can guarantee the quality,but it takes too long.However,the rapid detection method is mainly indirect measurement,and the corresponding relationship between the measurement signal and the mass concentration can not be checked on the spot.Based on the portable oscillation balance method,this study solved the problem that the equipment performance could not be checked on site by directly verifying the standard membrane weight,and there was no need to re-establish the corresponding relationship between the measurement signal and the mass concentration.The results show that under the conditions of horizontal vibration of 56.2~94.4 dB and vertical vibration of 58.4~96.5 dB,the relative errors of the balance and the standard filter value before and after the test are not more than±3.5%,and the standard deviation is less than 0.5%.The study of this method provides an effective quality assurance measure for the field rapid monitoring of particulate matter in the fixed polluted exhaust gas.
