测定固定污染源废气中非甲烷总烃的技术研究

Technical Study on the Determination of Non-methane Total Hydrocarbons in Waste Gas from Fixed Pollution Sources

为了提高挥发性有机物(VOCs)的检测水平,环境检测人员需要严格依据HJ38—2017标准测定固定污染源废气中非甲烷总烃(NMHC)。基于此,归纳总结了在监测和检测技术工作中需要注意的要点,对各步骤进行了分析,为从事环境污染监测及防治的技术人员提供了相关技术参考。

In order to improve the detection level of volatile organic compounds(VOCs),environmental inspectors need to strictly determine non methane total hydrocarbons(NMHC)in fixed pollution source exhaust gas according to the HJ 38-2017 standard.Based on this,the key points that need to be paid attention to in monitoring and detection technology work were summarized,and each step was analyzed,providing relevant technical references for technical personnel engaged in environmental pollution monitoring and prevention.
