污染源颗粒物监测结果偏离的原因探讨

对比玻璃纤维滤筒在不同温度下的前处理效果,对比滤筒、滤膜在特殊情况下采样的差别,综合现场采样及质量控制的因素,查找、分析低浓度污染源颗粒物监测数据出现较大误差、数据失实、缺乏代表性的原因,提出解决办法,确保监测数据的准确性。

To analyze the causes of the big errors,data inconsistent with the facts and lack of representation of the monitoring data on particulates in low concentration pollution sources by contrasting the pre-treatment effects of treating fiber-glass filter cartridges at different temperatures,also by contrasting the differences of filter cartridges and membranes sampled at special conditions,the general on-site sampling and the factors for quality control.The solutions are presented to ensure the accuracy of the monitoring data.
