Study and Application on Detection of Groundwater Water Quality On-line Monitoring Index

Due to the geological, hydrogeological feature along the main canal and construction characteristics of the inner drainage section engineering in the south-to-north water transfer project, pollutants might enter into the main canal with the groundwater, which may cause the main canal water quality risk. This study confirmed the rationality of the sensor research and guarantees the stability and accuracy of the groundwater detection based on the contrast of accuracy on the index of and comparison between groundwater sensor inspection and lab analysis data. For demonstration field monitoring at the same time, the running data was stable. Setting up demonstration project lays a solid foundation for building the key technology that is suitable for the water conveyance project of major water pollution control and water quality security system.
