Water pollution traceability method based on ultraviolet-visible spectrum data

Abstract

The invention provides a water pollution traceability method based on ultraviolet-visible spectrum data. The method comprises the following steps: S1, establishing a normalized water pollution traceability spectrum library; S2, obtaining a three-dimensional ultraviolet-visible-to-be-traced water quality fingerprint spectrum of a to-be-traced water pollutant; and S3, tracing the to-be-traced water pollutants intelligently. The principle is as follows: obtaining known water samples of known pollution sources of rivers, lakes and multiple industries (processing plants), and obtaining ultraviolet-visible-water pollution water quality fingerprint spectrum data under different dilution concentrations through detection and pretreatment; carrying out nonlinear fitting to obtain a three-dimensional ultraviolet-visible-water pollution water quality fingerprint spectrum of each known water sample; carrying out normalization processing on the obtained three-dimensional ultraviolet-visible-water pollution water quality fingerprint spectrum to form a normalized water pollution traceability spectrum library; and comparing the spectral features of the to-be-traced water pollutants with the spectral features of the known water sample in a traceability simulation mode, and obtaining a potential pollution list, and therefore, the method has the advantages of being high in traceability efficiency, high in timeliness and high in accuracy.

Description

technical field [0001] The invention relates to the technical field of water pollution traceability, in particular to a water pollution traceability method based on ultraviolet-visible spectral data. Background technique [0002] Water resources are one of the key resources for human production and life. With urbanization and economic and social development, the massive discharge of pollutants has caused varying degrees of pollution to the atmospheric environment and water environment, and the ecological environment has been severely damaged. my country's water resources and water environment are mainly faced with three problems: the shortage of fresh water resources, serious waste of water resources, and serious water pollution. There is a sharp contradiction between the actual situation of water environment and the demand for water environment in economic and social development. Protection and governance of water pollution have become the most concerned issues in modern soc...

Problems solved by technology

[0004] Traceability of water pollution is to determine the source of pollution. At present, most of the traceability of water pollution is done manually. This method is time-consuming and laborious and has poor accuracy.

At the same time, the method of simulating water quality by using information such as water ripples, rain and sunshine needs to collect a large amount of water ripples, rain and sunshine information, and its calculation is complex, limited and time-sensitive

The calculation methods for water pollution traceability include factor analysis, cluster analysis and chromatographic analysis. Among them, cluster analysis is a multivariate statistical analysis method that classifies samples or variables according to their degree of closeness in nature. It cannot accurately locate The data provided by the Water Pollution Environmental Monitoring Center is not accurate enough
