| titleOfInvention | Method for characterizing organic pollution characteristics of water body by applying ultraviolet spectrum |
| abstract | The invention discloses a method for characterizing organic pollution characteristics of a water body by applying ultraviolet spectrum peak data, which is characterized by comprising the following steps of: establishing a database according to the absorption characteristics of different organic matters in the 200-400nm ultraviolet region; in actual monitoring, firstly, ultraviolet absorption spectrum determination is carried out on a water sample, then, characteristic extraction is carried out on the ultraviolet spectrogram after peak separation, the ultraviolet spectrogram is compared with absorption wavelengths in a database one by one, and comparison results are expressed in a vector form. Obtaining a group of vectors representing pollutants aiming at each group of water samples, and judging whether the pollutant compositions are similar or not by calculating the included angle of the two groups of vectors; for two groups of water samples with similar pollutant compositions, further judging whether the pollutant concentration changes greatly by comparing vector lengths; the method is high in universality, and monitoring of specific pollutants can be achieved by adjusting the types of the pollutants in the database. |
