Detection Of TVOC And Odor Using Electronic Nose

VOCs and odor will have great threat on our health. Conventional analysistechnologies take too long and the cost of measuring is too high. The risk assessmentof TVOC and odor exist the problems of data sparse and time delay. The electronicnose can be used to monitor quickly, in real-time, and more testing points, and is akind of potential, powerful tool of analysis VOCs and odor quickly.In this paper, the sensors arrary was chosen according to the type of VOCs andodor firstly. Then electronic nose system was constructed. In the laboratory, in orderto determine the state of the electronic nose, choose commonly reagents-ethanol,benzene, toluene, chlorobenzene and styrene to calibrate it.In this article, TVOC and odor was taken as the detection target. Combining withthe electronic nose and PCA analysis technology, the pollution indexes andcorresponding risk assessment technology were built for assessing the industrial park.And combination with the GIS technology, the applicability research was carried outin Zhapu chemical industrial park. The results show that the technology canpreliminary used to assess the air pollution of the industrial park rapidly.In this paper, TVOC and odor was taken as the detection target. Combining withthe electronic nose and the two pollution indexes for risk assessment, risk assessmenttechnology were built for assessing the sewage treatment. The applicability researchwas carried out in A company of Jiashan and B sewage treatment of Suzhou. Theresults show that the technology can preliminary used to assess the air pollution of thesewage treatment rapidly.In this article, TVOC and odor was taken as the detection target. Combining withthe electronic nose and the two pollution indexes for risk assessment, risk assessmenttechnology were built for assessing the field soil and groundwater remediation. Andcombination with the GIS technology, the applicability research was carried out in thefield soil and groundwater remediation of Shanghai S chemical plant and thesurroundings. The results show that the technology can preliminary used to assess theair pollution of the field soil and groundwater remediation rapidly.
