AI Technical Summary

Technical Problem

Existing technologies for rainfall runoff pollution early warning do not provide comprehensive analysis of the physical and chemical properties of samples, and fail to fully combine the pollutant concentration and composition data of road sediments and rainfall runoff samples. This leads to an incomplete understanding of the sources and characteristics of pollution, a lack of in-depth analysis of pollutant migration and transformation models, and a weak linkage between warning signal generation and pollution control measures, affecting the accuracy and timeliness of predictions.

Method used

A rainfall runoff pollution early warning system is provided, which includes a sample analysis module, a pollutant model construction module, a water quality prediction module and a pollution control module. By comprehensively analyzing the physical and chemical properties of road sediments and rainfall runoff samples, a pollutant migration and transformation model is constructed, pollution early warning signals are generated and corresponding control measures are triggered.

Benefits of technology

It has significantly improved the accuracy of runoff water quality change trend predictions and the timeliness of pollution control, achieved efficient connection between early warning and prevention and control, and improved the accuracy and effectiveness of rainfall runoff pollution early warning.
