Three scientific and technological achievements of Anguang Institute passed the appraisal of achievements organized by the Provincial Department of Science and Technology

The three scientific and technological achievements of Anguang Institute have passed the appraisal of the achievements organized by the Provincial Department of Science and Technology. The monitoring instruments such as VOCs and greenhouse gas continuous automatic monitoring systems for key non-point source emissions, and the "Multiple Component Emission Flux Rapid Telemetry System" have passed the scientific and technological achievements appraisal organized by the Anhui Provincial Department of Science and Technology. The comprehensive performance indicators have reached the international advanced level. Experts of the appraisal committee thoroughly reviewed the three relevant materials and watched the operation of the instrument on the spot, fully affirmed and highly evaluated the research results, and recommended that the industrialization of the project results be accelerated as soon as possible. The successful development of these three monitoring instruments has provided advanced technical means for continuous automatic monitoring of organic pollutants in water, continuous automatic and accurate measurement of VOCs and greenhouse gas emissions from key pollution non-point sources, and rapid telemetry of vehicle emissions from industrial areas. "Quick monitor for low-concentration multi-component aromatic pollution in water bodies" is based on the pumping-type dynamic water sample collection update and three-dimensional fluorescence spectroscopy technology. The number of polluted components and different components in the mixed water samples are obtained by using the spectrum method and the alternating trilinear algorithm. The spectral load matrix of the paper proposes a comprehensive similarity index algorithm based on a sample database, which solves the analytical problem of overlapping three-dimensional fluorescence spectra of multi-component mixtures; a method of constructing a reference database for multi-component mixture correction by orthogonal mixing of sample concentrations is proposed. It effectively solves the problem of multi-collinearity between component samples; it realizes the rapid and automatic measurement of phenols, oils and polycyclic aromatic hydrocarbons in water and the alarm of exceeding the standard. "Key pollution non-point source VOCs and greenhouse gas continuous automatic monitoring system" has broken through the key technology of Fourier transform infrared spectrometer, designed the structure of the dual-arm scanning interferometer, and improved the stability and reliability of the system spectrometer; designed based on He -The precise scanning control circuit combined with Ne light and PSD improves the accuracy of the sampling interval of the interference signal; a quantitative analysis inversion algorithm based on synthetic analog calibration and instrument line shape correction is proposed to realize the emission of VOCs and non-point pollution from key pollution sources The greenhouse gas is continuously and accurately measured. "Air pollution multi-component emission flux rapid telemetry system" is based on the sunshade flux measurement technology, designed a solar automatic tracker combined with the initial positioning of the sun's position on the orbit and PSD photoelectric feedback accurate tracking, which realizes the rapid movement monitoring of the vehicle system ; Research on the diffusion characteristics of pollutant emissions from industrial areas, and propose a method for obtaining background spectrum of polluted gas measurement; based on the difference between normal and abnormal spectra, a linear correlation spectrum screening method is proposed; based on nonlinear least squares simulation calibration The column concentration inversion algorithm has been developed with independent intellectual property rights based on the sunshade method of pollutant gas emission flux calculation software, to achieve the industrial area VOCs, SO2, CO, NH3 and other multi-component gas emission flux rapid on-board measurement.
