Fuguang water source water quality early warning system ensures the timeliness and effectiveness of water source pollution warning

but the existing water quality monitoring technology can not quickly determine the source of pollution and early warning water quality changes. In order to maintain the accuracy of residents' drinking water keyword cement strength, the accuracy of last month's Diao cement strength test results is the fundamental guarantee of cement quality safety, and provides data guarantee for water quality monitoring and management, Fuguang water has developed a set of water quality early warning system for this purpose, which realizes the timeliness and effectiveness of water pollution warning

[new instrument] as we all know, water is the source of life and a necessary factor for human survival and social development. However, since the reform and opening up, although China's economic level, comprehensive national strength and people's living standards have been significantly improved, it has also brought many environmental problems. Among them, the source water pollution is one of the most serious problems

at present, the task of water supply security in China mainly includes three aspects: first, ensuring sufficient water supply, second, ensuring the quality of water supply, and third, ensuring the availability of water supply. In recent years, the government has built centralized drinking water sources and key river sections for automatic water quality monitoring, which has normalized the monitoring of surface water quality

however, the existing water quality monitoring technology can not quickly determine the source of pollution and early warning the change of water quality. In order to maintain the safety of residents' drinking water and provide data guarantee for water quality monitoring and management, Fuguang water has developed a set of water quality early warning system for water sources, The timeliness and effectiveness of water pollution warning are realized

system introduction

the so-called water quality early warning system refers to the digital collection and storage of many information such as landform, ecological environment, water quality and water resource distribution of the target water source by making full use of high-tech means such as geographic information system, remote sensing, multimedia, network and computer simulation on the basis of information technology and water quality simulation technology, At the same time, monitor and dynamically simulate the migration and transformation process of source water pollutants, form specific information and publish it to the public, becoming a scientific system integrating monitoring, prediction, simulation, calculation, decision-making and management

the water quality early warning system of the water source can be used to diagnose the sudden change of the water quality of the source water, and can take measures to deal with this sudden change, so as to realize the scientific decision-making and effective management of the water quality environment of the target water source by the policy-making department

cockpit of water source water quality early warning system

at present, Fuguang water source water quality early warning system has been successfully applied in some water quality automatic monitoring projects constructed by Fuguang water. In addition, Fuguang water has also established long-term good cooperative relations with many scientific research institutions and universities. After a large number of applications, the water quality early warning technology has been further improved, and water quality abnormalities have been found and reported in real time for many times, which adds a strong security guarantee for the water quality safety of water sources

water quality early warning

traditional deterministic water quality mathematical models usually require a large number of parameters of hydrology and water quality, which are more difficult to determine, This limits the accuracy of widely used and deterministic water quality mathematical models. The water quality early warning system developed by Fuguang water can significantly improve the generalization ability of the learning system by training multiple BP neural networks and synthesizing their conclusions

in the system, the LM (Levenberg Marquardt) algorithm is used in the prediction model to improve the convergence speed of the network, the early stop method is used to improve the generalization ability of the network, and the Leida criterion method is used to eliminate the abnormal data of the sample set. Many application results show that the BP neural network model has high prediction accuracy and fast prediction speed, and can get better prediction values for most water quality indicators. This BP neural network can be effectively applied to water quality indicators. In addition, because the material of this component is metal prediction and early warning and prediction system of water quality trend

system characteristics

compared with the water quality early warning system relying on traditional mathematical models, the water quality early warning system of Fuguang water source has the following characteristics: (1) it can be monitored by using historical monitoring data, and the investment cost is low. (2) The early warning sensitivity is high, and the system can reproduce the recent and 6. Results: the experimental results can be accessed arbitrarily, and the long-term water quality can be predicted, especially the recent water quality, and the error rate can be controlled at 8%

product application scenario

the water quality early warning system of Fuguang water source can be applied to: (1) reservoir drinking water source. A more comprehensive and sensitive water quality early warning ability can detect the hidden dangers of safety accidents earlier. (2) Small watershed monitoring. Divide the whole basin into governance units, actively monitor and take measures in time. (3) Cross section. Quickly predict the spread of water pollution and warn of cross-border pollution disputes

in recent years, sudden pollution of water sources has occurred frequently, which has had a great impact on our lives. The water quality early warning system of Fuguang water source can not only grasp the basic situation of drinking water source in a timely, comprehensive and accurate manner, but also prepare conditions for dealing with sudden pollution events of water source in time, which plays an important role in water quality monitoring and early warning of water source

Fuguang water has been pursuing to improve water ecology, optimize water system and ensure water safety. In the future, Fuguang water will continue to strengthen cooperation with scientific research institutions, closely follow the market development trend and policy release, do a good job in technological innovation and research, and continue to protect the safety of drinking water for residents
