化工園區(qū)日益成為化工發(fā)展的主流模式,園區(qū)的開(kāi)發(fā)和建設(shè)對(duì)地區(qū)經(jīng)濟(jì)發(fā)展起到了很好的帶動(dòng)作用,但同時(shí)也帶來(lái)挑戰(zhàn)。環(huán)境污染是急待解決的問(wèn)題之一,其中揮發(fā)性有機(jī)物(VOC)濃度超標(biāo)成為環(huán)境投訴的重要原因之一,相關(guān)處理方案成為技術(shù)開(kāi)發(fā)的重要熱點(diǎn)。

滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，測(cè)定了某化工園區(qū)空氣中揮發(fā)性有機(jī)物(VOC)以及非甲烷總烴,測(cè)定結(jié)果顯示化工園區(qū)空氣中非甲烷總烴與VOC的定量關(guān)系可以通過(guò)有效碳質(zhì)量濃度建立,即非甲烷總烴有效碳質(zhì)量濃度和VOC有效碳質(zhì)量濃度之和相等。并藉此定義總有效碳解析度(R)以表征空氣自動(dòng)監(jiān)測(cè)選定項(xiàng)目對(duì)空氣有機(jī)污染的覆蓋率指標(biāo),計(jì)算結(jié)果表明該空氣自動(dòng)監(jiān)測(cè)選定的11項(xiàng)指標(biāo)平均可表征該區(qū)域空氣有機(jī)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.
