摘要
为评估VOCs在线监测设备原始监测数据的准确性,建立了一种VOCs在线监测设备数据识别能力的评估方法。结果表明:8种VOCs在线监测设备在数据识别方面的表现存在一定的差异,原始数据与人工审核数据的平均相对偏差为-100%~56652%;相较于高碳物种,低碳物种的原始数据与人工审核数据平均相对偏差更大;根据应用案例分析提出"数据识别指数",对不同VOCs在线监测设备的数据识别能力进行定量区分。该方法可为今后VOCs在线监测设备评估工作提供一种全新的考核指标,还可以科学评判其他在线监测设备的快速分析应用能力。
In order to evaluate the accuracy of the original data of VOCs online monitoring equipments,an evaluation method for data recognition capability of VOCs online monitoring equipments was established.The results showed that there were some differences in the performance of the eight VOCs online monitoring equipments in data recognition capability,and the average relative deviation between original data and manual audit data ranged from-100%to 56652%.Compared with high-carbon species,a greater mean relative deviation between the original data and the manual audit data occurred for low-carbon species.According to the application case analysis,the data recognition index(DRI)proposed in this study could quantitatively distinguish the data recognition capability of different VOCs online monitoring equipments.This method not only provided a new assessment index for the evaluation of VOCs online monitoring equipments in the future,but also could make a scientific evaluation for the rapid analysis and application capability of other online monitoring equipments.
