固定污染源废气低浓度颗粒物测定的方法验证实验

为验证《固定污染源废气低浓度颗粒物的测定重量法》(HJ 836—2017),选取某燃煤电厂一台低浓度颗粒物排放机组开展实例监测,对全程序空白、同步双样和实样进行测试验证。结果表明,方法的平行性、精密度、检测限均达到HJ 836—2017的要求,可以用于固定污染源废气低浓度颗粒物的测定。

In order to verify the Weight Determination Method for Low-Concentration Particulate Matter from Stationary Pollution Source Waste Gas(HJ 836-2017),a low-concentration particulate matter emission unit of a coal-fired power plant was selected to carry out example monitoring,the overall blank,paired train sample and actual sample are tested and verified.The results of the test verification show that the parallelism,precision and detection limit of the method meet the requirements of the determination of low-concentration particulate matter in the exhaust gas of fixed pollution sources,and can be used for the determination of low-concentration particulate matter in the exhaust gas of fixed pollution sources.
