A Water Monitoring and Early Warning System of COD Using UV-Vis Spectroscopy

A distributed remote water monitoring and early warning system was proposed, which used the UV-Vis spectroscopy, GPS, GIS, 4G network, COD solution and database technology, to solve the problems including long detection cycle, limited scale and the lack of early warning mechanism of the water monitoring. 50 groups of original water sample from Ciqikou to Chaotianmen of Jialing River in Chongqing, China (every 5 km decorate a monitoring node, every 60 minutes collect data) was selected to study distributed remote water monitoring and early warning system of COD in UV-Vis spectroscopy based on 4G networks. The results indicated that through the system, not only the real-time display and storage, historical data query and warning function of water quality monitoring information could be achieved, but also the status of the water quality environment on the basis of COD can be reflected, which has a strong practicability and can provide environmental monitoring departments with real-time water quality information.
