Embodiment Construction
[0059] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0060] Such as Figure 1-2 As shown, the water pollution traceability and risk prediction and assessment method based on online spectral identification includes the following steps:
[0061] 1) Investigate possible pollutants and sources in the target waters;
[0062] Investigate potentially polluting sources of pollution, such as factories, sewage pipes, and gaps entering rivers from farmland near the target water area, and create a pollution fingerprint map to facilitate comparison and query to determine the possible source of pollutants;
[0063] 2) Place the immersion UV water quality online analyzer in the target water area to be monitored for a period of time to obtain the background value of the water quality of the local river and lake water;
[0064] The immersion UV water quality online analyzer needs to observe the water quality of...

The invention discloses a water body pollution traceability and risk prediction evaluation method based on online spectrum recognition, belongs to the technical field of surface water pollutant monitoring, traceability and risk evaluation, and includes exploring possible pollutant types and corresponding sources of a target water area and constructing a pollutant map; measuring a local river and lake water quality background value; carrying out real-time water quality monitoring and feeding back water quality data by utilizing an immersion type UV water quality online analyzer; constructing acloud computing platform to collect river and lake real-time water quality monitoring data fed back by the water quality analyzer and compare the water quality data in real time; according to the comparison result, if it is judged that pollutant leakage occurs, using a high-precision water quality traceability model based on a Kalman filtering method for pollutant traceability; performing pollution risk assessment rapidly according to the traceability result. The system constructed by the invention comprises a real-time online monitoring function and a cloud computing function, and a traceability and risk assessment target integrating the characteristics of data platformization, recognition accuracy, high computing speed, operation simplification and the like is realized.
Description
technical field [0001] The invention belongs to the technical field of surface water pollutant monitoring, traceability and risk assessment, and in particular relates to a water body pollution traceability and risk prediction and assessment method based on online spectral identification. Background technique [0002] In recent years, sudden water pollution incidents have been increasing year by year. Sudden water pollution incidents are uncertain and dangerous, and quickly affect the water supply system in a short period of time, leading to water outages, and through spread, transformation, coupling These mechanisms have seriously affected the urban ecosystem, and then caused complex social problems, becoming the primary threat to the safety of drinking water sources. In order to minimize the adverse effects of water pollution accidents, in addition to strengthening real-time monitoring of water quality, it is necessary to establish a system technology that can identify wate...
