化工园区日益成为化工发展的主流模式,园区的开发和建设对地区经济发展起到了很好的带动作用,但同时也带来挑战。环境污染是急待解决的问题之一,其中挥发性有机物(VOC)浓度超标成为环境投诉的重要原因之一,相关处理方案成为技术开发的重要热点。

滕州市浩瀚色谱仪器技术服务有限公司，测定了某化工园区空气中挥发性有机物(VOC)以及非甲烷总烃,测定结果显示化工园区空气中非甲烷总烃与VOC的定量关系可以通过有效碳质量浓度建立,即非甲烷总烃有效碳质量浓度和VOC有效碳质量浓度之和相等。并藉此定义总有效碳解析度(R)以表征空气自动监测选定项目对空气有机污染的覆盖率指标,计算结果表明该空气自动监测选定的11项指标平均可表征该区域空气有机污染的71%。

Chemical parks have increasingly become the mainstream mode of chemical development. The development and construction of parks have played a very good leading role in regional economic development, but they also brought challenges. Environmental pollution is one of the urgent problems to be solved. Excessive concentration of volatile organic compounds (VOC) has become one of the important reasons for environmental complaints, and related treatment schemes have become an important hot spot in technology development.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. has measured volatile organic compounds (VOC) and non-methane total hydrocarbons in the air of a chemical park. The measurement results show that the quantitative relationship between non-methane total hydrocarbons and VOC in the air of the chemical park can be determined by the effective carbon quality. The concentration is established, that is, the sum of the effective carbon mass concentration of non-methane total hydrocarbon and the effective carbon mass concentration of VOC is equal. And to define the total effective carbon resolution (R) to characterize the coverage index of air organic pollution by the selected items of air automatic monitoring. The calculation results show that the 11 indicators selected by the air automatic monitoring can represent the air organic pollution in the area on average. 71% of it.
