Design And Implementtation Of River Pollution Tracking System Oriented To Sudden Accidents

For a long time,although the management of heavy metal pollution in rivers in China has been continuously strengthened,due to illegal discharges of some factories and enterprises,the problem of heavy metal pollution in rivers in China is still serious.Rivers are the fresh water resources on which we live,so when sudden river heavy metal pollution accidents occur,we should take corresponding measures in time to prevent greater environmental pollution consequences.How to use the existing monitoring data to quickly and accurately find the pollution source company is very meaningful in reality.This article designs and implements an emergency-oriented river pollution tracking system that will realize the informationization of heavy river pollution sources in a certain river in a certain province,and can more accurately track and locate river heavy metal pollution source companies,thereby reducing the consumption of human,material and financial resources.Protect rivers from the source and reduce pollution.According to the current actual demand for the tracking of sudden heavy metal water pollution sources,this paper determines the use of hydrodynamic inversion method to track and trace the source of sudden heavy metal water pollution in onedimensional rivers through the study of the source of water pollution traceability,combined with modern information technology Design and implement the system.Firstly,according to the characteristics of heavy metals,the time-space change equations of heavy metal pollutants in one-dimensional river channel are determined;the time-space traceability model and pollutant emission model are constructed,and the emission time and position of the pollution source are obtained by solving the two models using the improved AFSA algorithm And the three parameters of emissions;an investigation method is designed for the investigation of pollution source enterprises.Then the system is designed for architecture,specific function design and database design,and the development-oriented tools and programming languages are used to implement the tracking system for sudden water pollution.Finally,by testing the system and analyzing the results,the results show that the system meets the user's needs and achieves the expected goals.
