Description

Technical Field

[0001] The invention relates to the technical field of riverbed sediment sampling, and in particular to a riverbed sediment sampling device containing organic pollutants. Background Art

[0002] Bottom mud is the sediment of rivers and lakes and is an important part of natural water bodies. When water bodies are polluted, some pollutants in the water can be stored in the bottom mud through precipitation or adsorption of particles. Under appropriate conditions, they are released again and become a secondary pollution source. This kind of pollution is called bottom mud pollution.

[0003] In the process of river and lake pollution control, sediment pollution control is one of the main difficulties and a common environmental problem. There is a dynamic balance of absorption and release between water bodies and sediments. When water bodies are seriously polluted, some pollutants can enter the sediments through precipitation, adsorption and other effects; when the pollution caused by external sources is controlled, various organic and inorganic pollutants accumulated in the sediments re-enter the overlying water bodies through physical, chemical and biological exchanges with the overlying water bodies, becoming a secondary pollution source that affects the water quality of the water bodies.

[0004] The exchange of pollutants between sediment and overlying water is very complex, which is not only affected by the underwater topography, sediment water content, pollutant content and concentration and other physical and chemical properties of the sediment itself, but also by the hydrodynamic characteristics of the overlying water and the physical and chemical properties of the overlying water such as the pH value, temperature, pollutant type and concentration of the overlying water itself. Moreover, pollutants are not only exchanged between sediment and overlying water, but different pollutants may also undergo physical and chemical reactions due to changes in external conditions, resulting in mutual transfer or transformation of pollutants.

[0005] At present, the sampling process for river sediment containing organic matter is relatively complicated, especially the lack of sampling devices that can walk on the riverbed and conduct flexible fixed-point sampling, which makes it difficult to adapt to the current sediment management needs.
