Research On The Method Of Monitoring Oil Spill Pollution Based On Spectrometer

With the continuous development of spectral technology and remote sensing imaging technology,the application of spectral technology has become more and more perfect,which makes the water pollution monitoring,especially in the water surface oil spill monitoring effect obvious.In addition,in response to the call of the country to build a beautiful China,more and more projects are being put into the oil spill monitoring research.Timely and accurate monitoring of the spectral data of the oil spill area is of great significance to the pollution control,which can minimize the adverse effects on the environment.But the oil spill film spectral data in the actual measurement surface,various traditional methods affected by the precision of data processing,such as geographical environment factors,resulting in the lower accuracy of the film recognition,and characteristics of oil spill oil and oil film thickness are difficult to analyze.Therefore,in order to ensure the guidance effect of oil spill monitoring results on the actual pollution control,we need to increase the research of oil spill target and improve the recognition ability of oil spill film thickness.First of all,this paper discusses the principle of several typical oil spill monitoring methods,and compares the advantages and disadvantages of various monitoring methods.The application of spectral method in the monitoring of oil spill oil film and the development of oil spill accident monitoring are analyzed.Secondly,the paper studies the types matching and thickness identification principle of oil film spectroscopy,and introduces the process of spectral data fitting analysis by software.Thirdly,in order to explore the characteristic band of oil film spectrum,the experiment of oil film spectroscopy in the laboratory was designed.The results obtained in infinite deep water of simulated natural environment show that there is a high linear relationship between the thickness of the oil film and the reflectivity of the oil film spectrum when the oil film is thinner.The spectral characteristics are mainly concentrated in the visible ultraviolet,green Light and red light band.Finally,in order to obtain the function of the oil film thickness and the spectral reflectance in the characteristic band,the spectral data of the oil film of the water surface are measured for the second time in the selected field environment.Based on the results of laboratory spectral measurements,the results of the fitting analysis of the field spectral data show that the oil film thickness and the corresponding spectral reflectance have a strong exponential function relationship under the thin film thickness.The experimental results show that it is feasible to determine the thickness of water surface oil spill film according to the results of the water film spectrum measurement.
