Abstract

The invention provides a water quality pollutant tracing method based on wavelet analysis. The method comprises the steps: step a, determining a water area to be monitored; step b, monitoring the COD value and the pH value of a water area of an observation point and the illumination intensity of the preset water depth of the water area to be monitored in real time, and judging whether the water area to be monitored is polluted or not according to the COD value, the pH value and the illumination intensity; step c, after it is judged that the water area to be monitored is polluted, respectively obtaining pollutant concentration change spectrums of water samples at the observation point and the sampling point; and step d, comparing the pollutant concentration change spectrum frequency of the observation point with the pollutant concentration change spectrum frequency of each sampling point one by one to determine the pollution source. The pollutant concentration change rule is inversed through wavelet analysis, and the pollutant concentration change spectrum frequencies of the water samples at the observation point and the sampling point are compared one by one to determine the pollution source, so that the judgment accuracy of the pollution source can be effectively improved, and the accuracy of the tracing result and the working efficiency during tracing are effectively improved.

Description

technical field [0001] The invention relates to the technical field of traceability of water pollutants, in particular to a method for traceability of water pollutants based on wavelet analysis. Background technique [0002] At present, the illegal discharge of sewage and waste water and sudden water pollution accidents will cause serious pollution and damage to rivers and other water systems and the ecological environment. Strengthen the online monitoring of pollutants exceeding the standard in rivers and lakes and reservoirs, and use the data analysis technology platform to build an online traceability technology for online analysis of water pollution, so as to quickly identify and seriously investigate the responsibility of polluting enterprises so that they dare not re-offend, and for timely identification and proper emergency response It is of particular significance to deal with sudden water pollution incidents. [0003] At the same time, the application of wavelet an...
