Automatic Monitoring Method for VOCs Emissions from Fixed Pollution Sources in Multiple Industries
Volatile organic compounds(VOCs)are one of the main pollution sources.Therefore,an automatic monitoring method for VOCs emissions from multi-industry stationary pollution sources is proposed.This study constructs a sampling tube using activated car-bon adsorbent for sampling,and analyzes other pollution characteristics using gas chromatography.Various different substances are sam-pled and analyzed separately under specified chromatographic conditions,each volatile organic compound can be well separated.The re-search draws standard curves for each substance,obtains VOC emissions from fixed pollution sources in multiple industries,and achieve automatic monitoring of VOC emissions from fixed pollution sources in multiple industries.The experimental results show that the pro-posed method can achieve real-time monitoring of VOCs emissions from fixed pollution sources in multiple industries,obtaining accurate automatic monitoring results of VOCs emissions and providing effective basis for the control of VOCs in multiple industries.
