Abstract
A device for in-situ measurement of substance migration and transformation on a sediment-water interface includes a floating platform. Three take-up and pay-off components are fixedly connected to the edge of a top surface of the floating platform. Each take-up and pay-off component comprises an L-shaped base, a cable take-up and pay-off assembly, vertical rods, a guide sheave wheel, an adjustment assembly and a first cable. Two DGT samplers are fixedly connected to bottom ends of two three take-up and pay-off components. Water quality monitoring sensors are fixedly connected to the two first cables fixedly connected to the two DGT samplers, respectively. A sediment collector is fixedly connected to a bottom end of the other take-up and pay-off component. Sampling can be performed in-situ directly through DGT flat plates to avoid the impact of environmental changes.
