Description

technical field [0001] The invention belongs to the fields of hydrology, water conservancy and environmental monitoring, and relates to a water sample sampling device, in particular to a disturbance-free high-precision deep-water sampling device. Background technique [0002] In recent years, with the rapid development of the economy, domestic surface water has been polluted to varying degrees. These pollutions threaten the safety of the environment and ecology, and affect the development of cities and the health of the people. Therefore, the monitoring of surface water has been widely used. s concern. Based on the urgent needs of human development for water resources, it is necessary to conduct water quality testing on surface water, select representative indicators, build a water resource security evaluation index system according to the connotation of water resource security, and quantify the overall status of water resource security in the testing waters , Dynamic resea...
