Abstract

The invention belongs to a sampler of water body sediment pore water and overlying water like lakes, rivers and reservoirs. The sampler comprises a manifold for lowering to a sampling area, a polypropylene membrane collection pipe is wound on a body of the manifold, an operation handle is arranged at the upper end of the manifold, two ends of the polypropylene membrane collection pipe are communicated with a pipe cavity of a solution collection pipe, the solution collection pipe is positioned in a cavity of the manifold, and the end of the solution collection pipe is guided out from the upper end of the manifold and is communicated with a drawing collection device. The manifold can be conveniently lowered to sediment and the overlying water by utilizing the operation handle, and convenience is brought to sampling operation of an operator; after the manifold is lowered to the sampling area, due to low permeability of the polypropylene collection pipe, interference of disturbance of a water body in the sampling area on sampling accuracy can be reduced, and a sample obtained by sampling is ensured to meet requirements of analysis testing of inorganic matters like metal elements, nitrogen and phosphor and other organic matters.

Description

technical field

[0001] The invention belongs to the technical field of environmental engineering, in particular to a sampler for sediment pore water and overlying water in lakes, rivers, reservoirs and other water bodies. Background technique

[0002] The water-sediment interface is an important place for physical, chemical and biological reactions between the sediment phase and the water phase in the water environment, and plays an important role in the migration and transformation of pollutants in the water body. Usually, the adsorption and release of pollutants in sediments are the source and sink of pollutants in the overlying water. Therefore, accurate acquisition and determination of pollutant content in sediment pore water and overlying water is beneficial to the study of biogeochemical cycle processes and provides theoretical guidance for water pollution and governance.

[0003] At present, there are mainly two ways to obtain sediment pore water: active and passive....
